;Tip: Use [https://translate.google.com/translate?hl=en&sl=en&tl=de&u=https%3A%2F%2Fwiki.gnucash.org%2Fwiki%2FTranslation&sandbox=1 Google translation] and select your language to get a translation of this document.
The concept of this document is to give you step-by-step instructions on how to create or update ''translation''s and other ''localization'' tasks for the gnucash project.  See [[Translation Status]] for the current status of the project with respect to translation contributions.

== Overview ==

GnuCash has several separate areas that need translations or localization, which are by priority:
;The [[#The glossary file|Glossary]]: A reference in form of a ''message catalog'' with roughly '''200''' terms that are commonly used throughout GnuCash and their '''explanation'''. Preferably it should be translated first for each new language to define a consistent terminology for the other parts.
:[https://hosted.weblate.org/engage/gnucash/ https://hosted.weblate.org/widgets/gnucash/-/glossary/287x66-grey.png]
;The [[#Translating the Program|Program]]: Its ''message catalogs'' contain all text messages for the application's user interface. It currently consists of roughly '''5000''' strings. Not all are equally important though.
: Some languages are currently maintained at the [[#translationproject.org]]: [{{URL:GH}}Gnucash/gnucash/blob/maint/po/CMakeLists.txt#L4-L5]
: For any other language [https://hosted.weblate.org/engage/gnucash/ https://hosted.weblate.org/widgets/gnucash/-/gnucash/287x66-grey.png]
:Please read at least [[#Adjust special messages]] and [[#Special characters and other tips]], if you use one of that services.
;The [[Windows Installer Translation|Windows Installer]]: It contains some '''20''' strings.
;The [[#How to translate the files containing the new account hierarchies|Account Templates]]: A set of ready to use account chart snippets ''for personal users'' that can be mixed and matched into a full chart of accounts during the creation of a new a new GnuCash file with currently '''115''' translatable account names.
:*If your government or other authorities offer specific templates ''for business users'', you can create them, too.
;The [[#Translating the GnuCash Guide and Help|Documentation]]: The Help Manual and the [[Concept Guide|Tutorial and Concepts Guide]]. These documents explain how to use GnuCash. They are written in DocBook, an XML variant.
;The [[#How to translate the website|Website]]: While mostly written in PHP/HTML, it uses ''message catalogs'', too. Currently it has '''430''' messages.
:[https://hosted.weblate.org/engage/gnucash/ https://hosted.weblate.org/widgets/gnucash/-/website/287x66-grey.png]
:* In theory one could also translate recent announcements from the '''news''' directory into the language specific subfolder, but ususally there are more important tasks around.
;The [[#How to create localized Income Tax Tables|Income Tax Tables]]: They require some knowledge of your regional tax rules and are related to ''account templates''.
;Currencies: GnuCash uses the translation of the ISO 4217 '''currency''' codes and names. This are maintained by the [https://salsa.debian.org/iso-codes-team/iso-codes ISO Codes Team]. If your language is missing or has issues contact them or contribute: [https://hosted.weblate.org/engage/iso-codes/?utm_source=widget https://hosted.weblate.org/widgets/iso-codes/-/iso-4217/287x66-white.png]
* Optionally you can [[#Check Files in Repo gnucash's doc Directory]] files, too.

== Available Resources ==
There are many resources to support you at gnucash.org and other places. Don't hesitate to use them.

=== gnucash.org ===
We have collected a bunch of useful information for you here in '''this wiki''' -
:''navigate'' from the [[GnuCash|main page]], or the [[Special:Categories]] or use the ''search'' function -
and on the '''website''' {{WebURL}}.

And we have several '''channels of communication''' and a few other useful tools:
:;IRC: The fastest way to get help is using the '''internet relay chat''' [[IRC]], as many of the developers hang out there and are eager to help.
:;Mailing lists: Translators will probably find two or three gnucash mailing lists of interest. If you can not find the answers to your questions in their [[Mailing_Lists#Mailing List Archives]], feel free to ask them.
::* For ''language and region specific questions'', where you should discuss terms and ask for proofreading of your work, use your languages mailing list. Currently we have
::*: '''gnucash-'''[pt_]'''br''',''' de''',''' es''',''' fr''',''' it''',''' nl'''.
::: If none exists for your language or nobody has an answer there, use the english lists:
::* ''General use questions'' and answers are found on the '''gnucash-users''' mailing list,
::* specific ''development questions'' go to the '''gnucash-devel''' list.
::* If you dislike the heavy traffic on the above lists, you should at least subscribe the [{{ListURL}}/mailman/listinfo/gnucash-announce gnucash-announce] list to get informed about new :releases.
:To ''subscribe'' or ''view archives'' of these lists follow the links to the [[Mailing Lists]].

=== translationproject.org ===
The [{{URL:TP}} Translation Project] coordinates the ''message cataloges'' of several '''programs'''
;Hosted Languages: See which languages they host on their [{{URL:TP}}domain/gnucash.html GnuCash page].
;Process: Learn about their process [{{URL:TP}}html/translators.html here].

If you want to help with an existing Translation Project translation or add a new translation under their aegis, please contact the ''language team'' using the information on their [{{URL:TP}}team/ team page].

;Coordinating Message Catalog Translations:
:;New Message Catalogs: The Translation Project requires that you use either an existing translation or <tt>gnucash.pot</tt> from the latest release as the basis for your translation.

:;Updating Message Catalogs: Usually you will use your po file from their site, but sometimes we apply global changes like removing the trailing colon from GUI labels. In that case you can save time by merging such updates from [{{URL:GH}}/Gnucash/gnucash/tree/maint/po our version].

;Other Components: The Translation Project handles only message catalogs of the program, so if you have ''glossaries'', ''account templates'' or ''documentation translations'' … you'll submit them by one of the following ways.

=== weblate.org  ===
Since 2020-12-14 the translations of some components, currently ''Glossary'', ''Program'' and ''Website'', are available at [{{URL:wl}} GnuCash @ Hosted Weblate]. Note that languages of the program managed by [[#translationproject.org]] are not listed at weblate.
* Only a web browser, no additional software required to contribute.
* Already as '''anonymous''' you can add ''suggestions'' and ''comments''.
* After you created there an '''account''', you can edit the translations.
** If you also have a [{{URL:GH}} GitHub] account, we can give you some feedback on your contributions.
* If you already have been a '''GnuCash translator''', tell us
*: on {{IRC-URL}} ([[IRC|help about IRC]]) or
*: by a mail to the gnucash-devel list your Weblate name to become a weblate/GnuCash reviewer there.
* We appreciate any help on the optimal configuration by '''experienced weblate users'''. You can contact the GnuCash team by {{IRC-URL}} or [[Mailing Lists]].

==== Other Web Based Translation Tools ====
Several services for translation coordination exist, see [[Improve Localization Process#Web Based Translation Tools]]. As we have no experience with them contact the gnucash-devel mailing list before using them.

=== Classical Direct Contribution ===
If you want to work on a translation that's not coordinated by the Translation Project or a new translation and you want to submit it directly to GnuCash, read on. If it's an existing translation please try to contact the last translator first using the contact information in the message catalog.

If you're starting a new translation it's much easier to begin with a tarball, which will include <tt>po/gnucash.pot</tt>; if you start from a [[Git]] clone you'll have to [[Building|build]] Gnucash yourself first to generate <tt>gnucash.pot</tt>.

=== On Other Sites ===
;Technical Reference: For many components we use the '''Gettext''' package. If you need help with <tt>msg*</tt> commands, read it's [{{URL:Gnu}}software/gettext/manual/gettext.html manual].
;General Translations Guidelines and Tips: General information about how to approach the translation of software can be found here:
:;TranslationProject:
::* {{URL:TP}}html/translators.html
::* {{URL:TP}}html/software.html
:;Weblate:
::* {{URL:wl doc}}
:;Gnome: As GnuCash is [[GTK]] based we follow their rules for consistency.
::* Human Interface Guide https://developer.gnome.org/hig/stable/ is multilingual. The most important section is ''writing-style'', but also ''keyboard-input'' is of interest for the program.
::* GNOME ''Documentation'' Style Guide https://developer.gnome.org/gdp-style-guide/
::* {{URL:GTP}}
::* {{URL:GTP}}/LocalisationGuide
:;KDE:
::* [https://l10n.kde.org/docs/translation-howto/index.html The KDE Translation HOWTO]

;Other Useful Sites:
:* Often, but not always, {{URL:wp}} has a good explanation and proper language links for special terms.
:* There are many online dictionaries, use a search engine like google, to find the best fitting.
:* An index of on-line dictionaries and a lot of other resources can be found at www.yourdictionary.com. 
:* Comparing articles on wikipedia in your language and english can be helpful.
:* In special cases the terminology database of the European Union [https://iate.europa.eu/info/documentation Inter Active Terminology for Europe] can be used, too.

== How to submit changes directly to GnuCash ==
Once you've got a translation ready for submission, there are three options:

=== Pull Requests at GitHub ===
Pull requests are the fastet way to get your work applied.

If you already are a [{{URL:GH}} github] user you can publish your work as a separate branch on your gnucash[-{[ht]docs|on-windows}] fork and send a pull request to the GnuCash team. If you wish to continue your work before the request was completed, simlply create a new working branch. After the pull request was completed you can delete the related branch again. See [[Git]] for details.
;Commit messages:
:# Start your commit message with <tt>L10N:<LL>: </tt>
:#: were <LL> - or ${LL} below - is your language code.
:# Append the output of <Syntaxhighlight lang="sh" inline>msgfmt -c --statistics ${LL}.po</Syntaxhighlight>
:;Example: <tt>L10N:de: 5423 übersetzte Meldungen.</tt>

=== Patches at Bugzilla ===
The easiest is to use [[Bugzilla]]: 
* [{{BugURL}}/createaccount.cgi Create an account] if you still have none or [{{BugURL}}/index.cgi?GoAheadAndLogIn=1 login],
* [{{BugURL}}/enter_bug.cgi?product=GnuCash&component=Translations&bug_severity=enhancement create an ''request for enhancement'' bug against the Gnucash ''component translations''], choose the version on which your patch is based and
* attach a patch
:containing the diff between the old files - if any - and your new files:
:* If you have [[Git]] installed, the easiest way to create the patch is <code>git format-patch origin/maint..maint</code>.
:* Else you can use ''diffutils'': <code>diff -u[r] <original path> <modified path> > <name>.patch</code>. See <code>info diff</code> for details.

=== Mailing lists ===
You can simply email your completed message catalog (<tt>.po</tt> file) to the developers at the [mailto:gnucash-devel@gnucash.org gnucash-devel] mailing list. We'd really rather you use Bugzilla or Github because those are much less likely to get lost or forgotten, but if you really find those too hard we'll try to accommodate you on the list.

== Translating the Program ==
To begin a translation you need either the message template file (gnucash.pot) if you're starting a new translation or the existing message catalog (xx.po or xx_YY.po, where xx is the ISO code for your language and YY the ISO code for a language-variant locale, see [[#Naming Convention|Naming Convention]]). These files are in the gnucash sources, which you can obtain either from our [{{URL:GH}}gnucash.git git repository] or by downloading the latest '''release''' tarball from [https://www.sourceforge.net/projects/gnucash/files/gnucash%020(stable) Sourceforge].

=== Get the source from Git ===
GnuCash uses [[Git]] as a version control system. [[Git|Click here]] for an introduction to Git.

The first thing to do is ''usually'', to download the latest STABLE branch, called '''maint''', of gnucash from git and get it to compile.  '''See [[Translation Status]] to choose which branch to use for translations'''.  Do not use the ''master'' branch ''unless specifically mentioned in [[Translation Status]]''.  Because the text in the ''master'' branch changes so much it would be a waste of time to translate  it.  Do not worry, when the ''master'' branch becomes stable the existing  translations in the STABLE branch will be merged.  Your work will not be lost.

Normally checkout the current stable branch:
<Syntaxhighlight lang="sh">
git clone https://github.com/Gnucash/gnucash ${SOURCEDIR}
cd ${SOURCEDIR}
git checkout maint
</Syntaxhighlight>

The argument '''${SOURCEDIR}''' above can be whatever you want your local directory to be called,
and is optional in the first line. If you leave it out, you'll have a directory called <tt>gnucash</tt> created
containing all the source code ''below your current working dir''.

Checkout the documentation (optional, but recommended):
<Syntaxhighlight lang="sh">
git clone https://github.com/Gnucash/gnucash-docs gnucash-docs
cd gnucash-docs
git checkout maint
</Syntaxhighlight>

==== Update your repository ====
After this initial git checkout, you can later update your local repository using
<Syntaxhighlight lang="sh">
git pull --rebase
</Syntaxhighlight>
from anywhere in the tree of ${SOURCEDIR}. We recommend to do it daily when you start your work.

=== Get packages, which are used while building  ===
* [[Dependencies]] contains the list of packages, which are used while building GnuCash. If some are missing the configuration by <tt>cmake</tt> or the build by <tt>make</tt> or <tt>ninja</tt> will fail.
* For working on .po files we use several commands starting with <tt>msg</tt>. This are part of '''gettext-tools'''.
:;Caution: Gettext versions < 0.20 are known not to extract the 'developer_name' xml node, which contains the msgid "GnuCash Project". Do not remove this msgid!
Under Linux use your package manager and install them.

=== Steps in the Build System ===
GnuCash uses the [https://cmake.org cmake] build generator to control the build of all components. Details are described in [[Building]]. The following short-form instructions work on Unix systems and assume that you have already set up the dependencies according to [[FAQ#Q:_I_heard_it_is_too_hard_to_compile_GnuCash.21|the FAQ]]. If you are building the unstable or master branches you'll need to use your package manager to install two more development packages, boost-all-devel and googletest.

==== Configuration ====
It's generally preferred to use a separate build directory. For translators it's convenient to make this a hidden directory in the source directory as that provides the least complicated paths in the translation template; hiding the directory prevents the extraction tool from including build products in the files searched for translatable strings. We'll call the directory <code>.build</code>. You can call it anything you like, just remember to start the name with a dot so that it's hidden.

Change directories to your ''build directory'' and run cmake to configure the build. In most cases translators will not need to install GnuCash and it will build any arguments: <Syntaxhighlight lang="sh">
cd ${BUILDDIR} # e.g. .build
cmake ..
</Syntaxhighlight>
tells cmake to configure the current directory using the CMakeLists.txt in the parent directory. If configuration fails or if you want to refine your build consult [[Building]]. 
  
==== Optional Compile ====
It is suggested that you compile the gnucash source code. It is a good idea to actually run gnucash with your new translations because it is quite helpful to see the phrases in the context of the running program. 

===== make =====
;Note: Advanced users might consider to use [[Build_Tools#Ninja|Ninja]] instead of [[Build_Tools#Make|Make]], but that is behind the scope of this page.
Next, compile gnucash in the ''build directory'':
<Syntaxhighlight lang="sh">
cd ${BUILDDIR} # e.g. .build
make
</Syntaxhighlight>

GnuCash can be run from the ''build directory'' as follows:
<Syntaxhighlight lang="sh">
cd ${BUILDDIR} # e.g. .build
GNC_UNINSTALLED=1 GNC_BUILDDIR=`pwd` bin/gnucash
</Syntaxhighlight>

It is a good idea to use absolute paths like this to insure you run 
the proper gnucash executable.  To run your distributions pre-installed version of
gnucash, under Linux usually you can type:
<Syntaxhighlight lang="sh">
/usr/bin/gnucash
</Syntaxhighlight>
<!--FIXME: Other OSes-->

In either case, you can easily switch between the various languages the 
gnucash has available by placing the LANG env var before the call to the
executable. You can find details in [[Locale Settings]].

==== Documentation ====
The ''GnuCash Help Manual'' and the ''Tutorial and Concepts Guide'' can either use the same [[CMake]] build system as the code or the older [[Build_Tools#Autotools|Autotools]].

* To make a browsable documentation set with Autotools:
*# <code>git clone gnucash-docs</code> or unpack a gnucash-docs tarball
*# create a hidden build directory just as you did for GnuCash itself
*# run autogen.sh <Syntaxhighlight lang="sh">
./autogen.sh
</Syntaxhighlight>
*# change directory into the build directory <Syntaxhighlight lang="sh">
cd .build
</Syntaxhighlight>
*# run the following commands <Syntaxhighlight lang="sh">
../configure
make html
</Syntaxhighlight>

* To make a browsable documentation set with CMake:
*# <code>git clone gnucash-docs</code> or unpack a gnucash-docs tarball
*# create a hidden build directory just as you did for GnuCash itself
*# change directory into the build directory <Syntaxhighlight lang="sh">
cd .build
</Syntaxhighlight>
*# run the following commands <Syntaxhighlight lang="sh">
cmake ..
make html
</Syntaxhighlight>

The new documentation home pages will be
:<code>guide/<locale>/gnucash-guide/index.html</code> and
:<code>help/<locale>/gnucash-help/help.html</code>,
where <locale> is one of <code>C, de, it, ja, or pt</code> (English, German, Italian, Japanese, or Portuguese respectively). You can use the <code>file:</code> URL scheme to point your browser to one of them; the links will work from there.

=== Naming Convention ===
The language code is of the following form:
:;<language>[_<REGION>][.<Charset>][@modifier]:using the well known ISO codes [{{URL:wp}}List_of_ISO_639-1_codes 639-1] for '''language'''s and [{{URL:wp}}ISO_3166-1 3166-1] for '''region'''s, which are in most cases countries .
:* Only ''if no 2 letter code exists'' for your language in ISO_639-1, use the 3 letter code from [{{URL:wp}}List_of_ISO_639-2_codes ISO_639-2].
* If you are the first translator for your language, you should
** name your files and directories ''only with your language code''.
** set <tt>Language:</tt> in the header of your po file with the full (language and region) code, if significant.
: So all people using your language despite of their region will benefit from your work.
* If there are parts, which are ''specific for your region'', e.g. business account templates respecting local law, then they should be in a <language>_<REGION> directory.
* The common '''charset''' in gnucash is [{{URL:wp}}Utf8 utf8].
* In the rare case ''different scripts'' are used for the same language like kyrilic and latin add for the less used the '''modifier''' e.g. <tt>sr@latin</tt>.

In the following parts of this document 'XXXX' and 'LL' refer to your language code.

=== Contact the maintainer of your language ===

To find out who is the last person to work on your language, look near the 
top of the po/XXXX.po file which corresponds to your language.   If your 
language does not have a .po file available, see the next section.

The beginning of your .po file should look something similar to this:
<syntaxhighlight lang="po" highlight="13">
# Localization for Portuguese-Brazil
# Copyright (C) 2003 Free Software Foundation, Inc.
# Jon Lapham <lapham@extracta.com.br>, 2003
# Jose Carlos Nascimento - <joseca@psabs.com>, 2001.
# 
msgid ""
msgstr ""
"Project-Id-Version: GnuCash 1.8.3\n"
"Report-Msgid-Bugs-To: https://bugs.gnucash.org/enter_bug.cgi?"
"product=GnuCash&component=Translations\n"
"POT-Creation-Date: 2003-05-16 16:42-0300\n"
"PO-Revision-Date: 2003-06-02 12:00-0300\n"

"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=n != 1;\n"
</syntaxhighlight>

Look to see who the "Last-translator" was, and send an email to that person 
and ask what you can do to help.  This is important because if there already 
is an active maintainer of the translation file, you should interact directly
with him or her.  If there is no Last-Translator, or that person is not 
maintaining the file actively (and tells you to take over or does not answer in reasonable time), you will become 
the maintainer and you should change the "Last-Translator" to your name and 
email address.

=== The glossary file ===
Inside the po/glossary/ directory should be a "glossary" file for your 
language.  This file contains a bunch of ''commonly used terms'' found in GnuCash - and the explanation of a few very specific for GnuCash like the disambiguation between ''bill'', ''invoice'' and ''voucher''.
It is recommended that you '''get this file translated first''', and use it as a 
guide when translating the real .po file or the documentation.  Please keep in mind that this file will ''never be visible to a user''! The glossary file is only a tool for you, the translators! I repeat: The strings from the glossary file will ''never'' be user-visible, they are only used by you, the translator.

::;Todo: The current files have a very informal form. To make them more useful like conversion in tool specific glossary formats, we should replace <syntaxhighlight lang="po">
msgid "generic term: term"
</syntaxhighlight> by <syntaxhighlight lang="po">
msgctxt "generic term"
msgid "term"
</syntaxhighlight>

# Go into the glossary directory: <Syntaxhighlight lang="sh">
cd po/glossary/
</Syntaxhighlight>
# If your .po glossary file ''does not exist'' or ''is older than'' <tt>gnc-glossary.txt</tt>, create the template: <Syntaxhighlight lang="sh">
./txt-to-pot.sh gnc-glossary.txt > gnc-glossary.pot
</Syntaxhighlight>
# Create or update your language's glossary file:
#* If your .po glossary file ''does not exist'', 
## use this gnc-glossary.pot file to create it with <Syntaxhighlight lang="sh">
msginit # add -l<locale> if different from your settings
</Syntaxhighlight>
## Add your file into the <tt>set_dist_list(po_glossary_DIST ...)</tt> command in <tt>glossary/CMakeLists.txt</tt> <Syntaxhighlight lang="sh">
set_dist_list(po_glossary_DIST CMakeLists.txt bg.po ca.po da.po de.po el.po es_NI-policy.txt es.po fr.po gnc-glossary.txt he.po
        hr.po hu.po it.po nb.po nl.po pl.po pt_BR.po pt.po ru.po rw.po sk.po sv.po txt-to-pot.sh vi.po zh_CN.po zh_TW.po)
</Syntaxhighlight> to get it in the tarball.
## After changing CMakeLists.txt you have to rerun <Syntaxhighlight lang="sh">
cmake # add your options
</Syntaxhighlight>
#* If your .po glossary file ''exists'', but is older than <tt>gnc-glossary.txt</tt> use the msgmerge program to update it: <Syntaxhighlight lang="sh">
msgmerge --previous -U LL.po gnc-glossary.pot;
</Syntaxhighlight>
# Now open your language's glossary file and translate it completely.
# Don't forget to [[#Check syntax and statistics of your .po file]].

==== Terms missing or inadequate in the glossary file ====
If you detect an important term which is missing or could be better explained,
* create a pull request at github or
* [[Bugzilla#Using_Bugzilla|open a bug]] for Product:GnuCash, Component:Translation and add a [[Git#Patches|patch]]
: for the ''source file'' '''gnc-glossary.txt'''.
With the exception of the header the lines of this file are alphabetical sorted and have the form: <Syntaxhighlight lang="text">
Msgid<TAB>Comment
</Syntaxhighlight>
:;Reminder: Does your editor enter <TAB>s or will it replace them with <Space>s?
To test it, run the following steps after you changed gnc-glossary.txt:
# To generate a new gnc-glossary.pot: <Syntaxhighlight lang="sh">
./txt-to-pot.sh gnc-glossary.txt > gnc-glossary.pot</Syntaxhighlight>
# run above ''msgmerge'' command for your LL.po,
# check and translate the new string in this updated glossary file.
# If successful, update all *.po files with: <Syntaxhighlight lang="sh">
for i in *.po; do echo -n "$i:"; LANG=C msgmerge --previous -U $i gnc-glossary.pot ; done
#old form: find *.po -exec /usr/bin/msgmerge --previous -U '{}' gnc-glossary.pot \;
</Syntaxhighlight>
;Note: The last step can also be done by a maintainer.
:<tt>LANG=C</tt> is only recommend for maintainers to get english error messages.

=== Get a fresh template ===
The ''Portable Object Template'' (.pot file) is a collection of all translatable strings.

It is important, to repeat this step e.g. after you asked a developer to change an insufficient string or you got an announcement about changed strings like commit messages starting with "<tt>I18N: </tt>" or containing a "<tt>[I18N]</tt>" flag.

:;Tip: If you have problems with this section, you download instead the "current template" from [{{URL:TP}}domain/gnucash.html the translationproject.org]. But keep in mind it is based on the last release and does not contain recent changes.

# If your repository is no fresh checkout, you should first [[#Update your repository]]: <Syntaxhighlight lang="sh">
git pull --rebase
</Syntaxhighlight>
# Only on the first run see [[Building]] to set up your build environment depending on your OS.
#;Note: As you can use <tt>make</tt> or <tt>ninja</tt>, on this page we write always <tt>make <target></tt>. If you decided to use ninja, execute <tt>ninja <target></tt> instead.
# Then in gnucash, a specific command ''at the '''top-level''' of the build tree'' (or source tree, if you do not use a separate build directory) will perform all necessary steps for this: <Syntaxhighlight lang="sh">
cd ${BUILDDIR} # adjust ${BUILDDIR}
make pot
</Syntaxhighlight>
# If make complains <Syntaxhighlight lang="console" inline>make: *** No rule to make target `<path/to/missing-source-file>', needed by `gnucash.pot'.  Stop.
</Syntaxhighlight> there are obsolete relicts from a previous build. Just run <Syntaxhighlight lang="sh">
make clean  # remove obsolete files
make pot    # try it again
</Syntaxhighlight>
# Now go into the po directory: <Syntaxhighlight lang="sh">
cd ${SOURCEDIR}/po # adjust ${SOURCEDIR}
</Syntaxhighlight>
If your language file ''already exists'', continue with [[#Update an existing .po file]].

=== Build a new .po file ===

If there is no .po file for your language, then you can start a new one. Start by 
<SyntaxHighlight lang="sh">
msginit [-lLL[_RR]] [-i<path/to/>gnucash.pot]
</SyntaxHighlight>
where <tt>LL</tt> is your language and <tt>RR</tt> your region code, if there is already a different LL.po like e.g. ''pt'' and ''pt_BR''. 
: -i<path/to/>gnucash.pot is required, if you use a separate build dir,
: -l... is only required, if your target is different from your environments current language.
This will initialize the meta information with values from your user environment.
;Note: msginit  0.19.3 is querying an obsolete address of the translation project for language teams, but that doesn't matter.

If that does not work you can copy the file <tt>gnucash.pot</tt> into a work file named <tt>LL.po</tt> and just edit this file.

==== Adjust the header ====
The top of the .po file should be edited somewhat. Most of this adjustments should already be done by <tt>msginit</tt>, but if you copied the template, you will have to adjust all.

* The comments at the top of the file should be changed to be current: <SyntaxHighlight lang="po">
# Messages in Deutsch fuer GnuCash
# Copyright (C) 1999 Free Software Foundation, Inc.
# Jan-Uwe Finck <Jan-Uwe.Finck@bigfoot.de>, 1999.
</SyntaxHighlight>
:Expand the copyright comment by a list of <code><Translator name> <email address>, year[ range]</code> in ''reverse'' historical order. Then you can later copy the list into <tt>translator-credits</tt>.
:* This is also a good place to record ''typographic conventions'', if more than one person work on the file: <SyntaxHighlight lang="po">

* The first, empty msgid "" contains information for you and the gettext tools. Each line of the msgstr contains a '''capitalized entry''', a colon and a value. ''Replace all uppercase words'' with something appropriate. In this case, you will be the first author of the translation, and also the

==== Adjust special messages ====
* There is currently one '''special string''': <SyntaxHighlight lang="po">

msgid "translator-credits"
msgstr ""
"Joachim Wetzig, 2019\n"
:
"Jan-Uwe Finck, 1999\n"
"\n"
"Verbesserungsvorschläge zur Übersetzung an gnucash-de@gnucash.org"

</SyntaxHighlight>
:This will appear in <tt>Help->About->Credits->Translation</tt>. So you should enter your ''name'' or that of your team and an ''email'' address where users can contact you for typos and gifts.
:;Tip: After some time more persons would have worked on the translation. Then you can expand it from your header comments to: <SyntaxHighlight lang="po">
msgstr ""
"<current translator>, <years>\n"
"<previous translator>, <years>\n"
:
"<first translator>, <years>\n"
"\n"
"Send suggestions, critizism and questions about this translation to\n"
"Klingon speaking GnuCash community <gnucash-tlh@gnucash.org>\n."
"To avoid moderation we recommend to subscribe at\n"
"<a

# Don't forget to replace Klingon (tlh) by your language and translate the rest!
</SyntaxHighlight> If a list exists, we suggest to remove the email address of individuals for data protection reasons.

==== Prepopulate your file with translations from your glossary and other projects ====
The basic idea is decribed in [{{URL:Gnu}}software/gettext/manual/html_node/Compendium.html#Compendium Gettext Manual: Using Translation Compendia]. Your translator tools might already support compendia. If not, i.e you are using a plain text editor, here is the manual way:

There are in total 3 programms in use:
:;msgcat: Concatenates and merges the specified PO files.
:;msgmerge: Merges two or more Uniforum style .po files together.
:;msgattrib: Filters the messages of a translation catalog according to their attributes or manipulates their attributes.

:;Example: To merge a compendiumn like our glossary:
<SyntaxHighlight lang="sh">
cd ${SRCDIR}/po
# Gettext manual's suggestion to merge compendia without old po file:
msgmerge --compendium glossary/${LL}.po -o ${LL}.po /dev/null ${BUILDDIR}/po/gnucash.pot
# Perhaps better:
msgmerge -U ${LL}.po --compendium glossary/${LL}.po ${BUILDDIR}/po/gnucash.pot
</SyntaxHighlight>

===== GOffice =====
Gnucash has borrowed a couple of source files from [{{URL:GH}}GNOME/goffice goffice]. Those files contain a number of translatable strings. The goffice translation teams have already put effort in translating those in many languages. To reduce our translation effort, the script linked in [[I18N#Borrowing Code]] can be used to import these translations into our own po files.

If the goffice part for your language is incomplete, you might consider to offer them to update their file with your work.

===== GTK3 =====
Stock buttons became deprecated in their version 3.10. They included:
# a label with mnemonic,
# for which the translation was already done in the gtk domain,
# a unique icon was associated. 

So they are no longer used since gnucash 3.0. We use still the same labels, but the GTK translation is not directly used.

You can save some work by merging the po file of your language from GTK3, i.e. from https://gitlab.gnome.org/GNOME/gtk/tree/gtk-3-24/po into your gnucash po file.

:;Example: To merge fitting translations from GOffice and GTK:
<SyntaxHighlight lang="sh">
#Example to merge common parts from po files in GOffice and GTK

# Variant A: in single steps to watch their results
## 1. join 3. party translations
msgcat --use-first -o tmp.po ${LL}.po ${GOFFICEPATH}/po/${LL}.po ${GTKPATH}/po/${LL}.po
## 2. Remove unused messages. Authoritativ is gnucash.pot:
msgmerge tmp.po ${BUILDDIR}/po/gnucash.pot | msgattrib --no-obsolete > {$LL}.po
rm tmp.po

# Variant B: in one command:
msgcat --use-first ${LL}.po ${GOFFICEPATH}/po/${LL}.po ${GTKPATH}/po/${LL}.po | \
msgmerge ${BUILDDIR}/po/gnucash.pot | \
msgattrib --no-obsolete > {$LL}.po
</SyntaxHighlight>

==== Adjust po/CMakeLists.txt ====
Also include your language code into the ''NEW_LINGUAS variable'' in the '''CMakeLists.txt''' file in the ''po folder'' of your ''source directory'':

<SyntaxHighlight lang="sh" highlight="8">
# Set of available languages:
# * managed at the Translation Project (TP):
set (TP_LINGUAS az ca cs da eu fa ja nl rw sk sr sv tr uk zh_CN)
# * already marked as external at TP:
set (GC_LINGUAS ar bg de el en_GB es fi fr gu he hi hu it kn ko lt lv mr nb ne pl pt pt_BR ro ru ta te ur vi zh_TW)
# * New or unmarked: The release manager should announce them to TP 
# and when listed there move in the respective group above.
set (NEW_LINGUAS as brx doi es_NI kok kok@latin ks mai mni mni@bengali)

set (ALL_LINGUAS ${TP_LINGUAS} ${GC_LINGUAS} ${NEW_LINGUAS})
</SyntaxHighlight>

''CMakeLists.txt'' is a file, which controls the configuration of the build process. So after changing it, you have to '''rerun cmake'''. Some IDEs like [[Eclipse]] will do it automagical for you. 

As part of the build your <tt>LL.gmo</tt> file is generated in the po directory of your build tree. Finally ''make install'' will copy it to the place, where it will be found at runtime. If you forget one of the steps, your translated language will not appear.

Continue with [[#Translating the .po file]].

=== Update an existing .po file ===

Before you begin actual translation work, you should update the gnucash.pot 
file and use this to update your .po file.  This process will insure that 
you have the latest translatable strings.

If your language file ''already exists'', update it using the ''msgmerge'' program. This will move the old translations of unchanged strings in the new file: <syntaxhighlight lang="sh">
msgmerge --previous -U LL.po gnucash.pot
</syntaxhighlight>
;Note: If you had choosen a ''separate build directory'', e.g. <tt>.build</tt>, adjust the path in above command: <syntaxhighlight lang="sh">
cd ${SRCDIR}/po # adjust ${SRCDDIR}
export BUILDDIR=../build # adjust this
msgmerge --previous -U LL.po ${BUILDDIR}/po/gnucash.pot 
</syntaxhighlight>

;Separate commits for "noise" and real work: You should now run <tt>git commit</tt> or ''create a patch'' <tt>"L10N:<locale>: Merge recent template"</tt>.
: This will contain only the "noise" from the updated pot file as usually many line numbers change.
:; Diff example after msgmerge: <syntaxhighlight lang="diff">
 #. Business options
-#: ../src/app-utils/app-utils.scm:303
-#: ../src/business/business-gnome/gncmod-business-gnome.c:117
+#: ../src/app-utils/app-utils.scm:322
+#: ../src/business/business-gnome/gncmod-business-gnome.c:119
 msgid "Business"
 msgstr "Geschäft"
</syntaxhighlight>
:Hiding your real changes in hundreds of such sections will make it really hard for your coworkers to find them.

After having done your [[#Translate the strings|translation]] you [[#Submitting|submit]] a second commit or patch containing your actual work <tt>"Update <locale>.po"</tt>.

You should also do it, if your current translation tool uses '''other format settings''' like line breaks as the previous tool. In this case just open the file, save it and <tt>git commit</tt> or ''create a patch'' <tt>"L10N:<locale>: Preparation: Reformating"</tt>.
:;Example in KBabel format: <syntaxhighlight lang="po">
#: ../src/app-utils/business-prefs.scm:33
msgid "The format string to use for generating customer numbers. This is a printf-style format string."
msgstr "Используемая строка форматирования для создания номеров клиентов. Её формат соответствует printf."
</syntaxhighlight>
:;Example in PoEDit format: <syntaxhighlight lang="po">
#: ../src/app-utils/business-prefs.scm:33
msgid ""
"The format string to use for generating customer numbers. This is a printf-"
"style format string."
msgstr ""
"Используемая строка форматирования для создания номеров клиентов. Её формат "
"соответствует printf."
</syntaxhighlight>

;Review the file header:
* <tt>Project-Id-Version should be ''GnuCash {{Version}}'' and
: <tt>POT-Creation-Date</tt> should be recent. If they are not, you probably forgot [[#Get a fresh template]] or [[#Updating an existing .po file]].
* The <tt>PO-Revision-Date</tt> should be >= <tt>POT-Creation-Date</tt>.
Some, but not all tools will do this reliably for you.

=== Translating the .po file ===

Finally.  You are ready to do some translating!

The .po source files are plain text files.

==== Tools ====
Some ''plain text editors'' offer a specific ''syntax highlighting for .po file''s, but there are also specific tools you can use:
* [{{URL:wp}}Emacs Emacs] has a po-mode to edit po files.
* [{{URL:wp}}Geany Geany], an editor with sytax highlighting and a little bit more
* [{{URL:wp}}Gtranslator GTranslator] is another tool but we recommend not to use it because the version of 2006 doesn't support all of the interesting elements inside the po file. Update this, if you know it is fixed.
* ''Lokalize'' is the successor of KBabel since KDE4.
* ''[https://poedit.net/ Poedit]'' to finish the PO file edit and build.
: [{{ListURL}}/pipermail/gnucash-devel/2018-September/042808.html Version 2.1.1 had issues]
* ''[https://poeditor.com/ POEditor]'' can be used online.
* ''[{{URL:wp}}Translate_Toolkit translate-toolkit]'' is a python based suite. It is also used by sevices like weblate.
* Wikipedia:

** [{{URL:wp}}Comparison_of_computer-assisted_translation_tools Comparison of computer-assisted translation tools]
(feel free to add more tools here)

==== Gettext source (.po) file format ====
===== Record Format =====
A record in a po file has the following form:
<syntaxhighlight lang="po"><empty or only white-space>
#  translator-comments
#. extracted-comments
#: reference…
#, flag…
#| msgctxt previous-message-context
#| msgid previous-untranslated-string
msgctxt optional-message-context
msgid untranslated-string
msgstr translated-string
</syntaxhighlight>
*The ''empty or only white-space'' line is the record separator.
*In ''translator-comments'' you can put your own notes.
*The ''extracted-comments'' are notes from the programmers for you.
* One or more ''reference''s tell you, where the message appears in the sources.
* The most important ''flags'' will be explained below in [[# Common Flags]] and [[#Special characters and other tips|source language format flag]] will be explained below.
* The ''previous-*'' entries will only appear, after <tt>msgmerge --previous …</tt> for fuzzy messages to show what changed.
* An ''optional-message-context'' has the purpose to distinguish equal msgids with different meanings.
* The ''msg*'' should explain themself above.

;Example:Here is an example of translating some text into German:

Before:<syntaxhighlight lang="po">
#: messages-i18n.c:11
msgid ""
"The GnuCash personal finance manager.\n"
"The GNU way to manage your money!"
msgstr ""
</syntaxhighlight>
After, the translation in the de.po file:
<syntaxhighlight lang="po">
#: messages-i18n.c:11
msgid ""
"The GnuCash personal finance manager.\n"
"The GNU way to manage your money!"
msgstr ""
"GnuCash: Ihr persoenlicher Finanzmanager.\n"
"Der GNU-Weg, ihr Geld zu verwalten!"
</syntaxhighlight>
You should read through every translation in the .po file at least once.

===== Common Flags =====
====== Fuzzy Flag ======
If you see a string that has the phrase <code>#, fuzzy</code> in the flags comment above it, review the translation and confirm it by removing
* the <tt>, fuzzy</tt> flag, but no other flags like <tt>, c-format</tt>,
* the <tt>#| msgid</tt> lines, and in some cases
* the <tt>#| msgctxt</tt> line.
A fuzzy translation means that the translation will be ignored by the program.

There are at least 2 reasons for the fuzzy flag:
# one of the <tt>msg*</tt> programs took some guess about what the translation might be from similar msgids,
# in a previous version you had a valid translation, but a programmer changed (parts of) the msgid.

After you finish translating, you should not have any "<tt>#, fuzzy</tt>" strings left. Remember, a string marked as "fuzzy" means it will not be translated in the program. You can filter for fuzzy messages by running <syntaxhighlight lang="sh">
cd ${SOURCEDIR}/po
msgattrib --fuzzy ${YOUR_LANGUAGE}.po
</syntaxhighlight>

;Example fuzzy message: <syntaxhighlight lang="po" highlight="2-3,5">
#: messages-i18n.c:35
#, fuzzy, c-format
#| msgid "There was an error opening the file %s."
msgid "There was an error writing the file %s."
msgstr "Es gab einen Fehler beim Oeffnen der Datei %s."
</syntaxhighlight> Here the msgid was changed from "opening" to "writing". You need to correct the translated string, remove the line(s) with the old msgid "<tt>#| msgid …</tt>" and the 'fuzzy' flag, because only then the translation will actually appear in the program.
;Example fuzzy fixed: <syntaxhighlight lang="po" highlight="2,4">
#: messages-i18n.c:35
#, c-format
msgid "There was an error writing the file %s."
msgstr "Es gab einen Fehler beim Schreiben der Datei %s."
</syntaxhighlight> Notice that <code>#, c-format</code> was ''not removed''.  That is correct, you should leave that.
:;Tip: If all fuzzy strings were fixed (<syntaxhighlight lang="sh" inline>msgattrib --fuzzy $LL.po</syntaxhighlight> returns nothing), you can also bulk remove the previous messages with <syntaxhighlight lang="sh">msgattrib --clear-previous -o $LL.po $LL.po</syntaxhighlight>

====== Format Flags ======
Because parts of GnuCash were written in different programming languages, there appear at least 2 different format flags:
;c-format: Format specifier: <code>%</code>
:When you see the comment "c-format", it means that the format codes in the translatable string are referring to C formatting codes.  So, '%s' means text, '%d' means an integer, etc...
;scheme-format: Format specifier: <code>~</code>
;Todo: Which parts of [[#Special_characters_and_other_tips]] would better stay here?

===== Orphaned Records =====
At the end of your file you might see records like <Syntaxhighlight  lang="po">
#~ msgid "Enter an Online Direct Debit Note"
#~ msgstr "Online-Lastschrift eingeben"

#~ msgid "Debited Account Number"
#~ msgstr "Konto-Nr. des Zahlungspflichtigen"

</syntaxhighlight>
They have no reference line. This records are no longer in use and you can remove them.

==== Translate the strings ====
Each message to translate is then given in turn in the PO file. For example, an untranslated entry might be:
<syntaxhighlight lang="po">
#: lib/error.c:88
msgid "Unknown system error"
msgstr ""
</syntaxhighlight>

The empty '''msgstr''' string has to be filled with the translation for the string shown after '''msgid'''. If you were a German speaker, say, the entry once translated might look like:
<syntaxhighlight lang="po">
#: lib/error.c:88
msgid "Unknown system error"
msgstr "Unbekannter Systemfehler"
</syntaxhighlight>

You just produce a translation for all entries in the PO file, one after another, respecting the overall file format and the quoting needed for special characters, when needed. Observation and intuition may allow you to grasp what the format should be; the precise rules for PO files are given in the GNU gettext manual. The msgfmt program is helpful for pinpointing formatting errors.

===== Contexts =====
;Important: With Gnucash 3.7 the first 2 forms got replaced by [[#Message Context]]. The description of the old types is only kept for some time to help updating older catalogs.

At some places, GnuCash uses "disambiguation prefixes" in translatable strings. Here is an old explanation:
{{ListURL}}/pipermail/gnucash-devel/2005-October/014236.html ; more explanation is also here: https://wiki.gnome.org/GnomeI18nDeveloperTips.

There are at least 2 ''use cases'':
* '''Abbreviations''', i.e. for columns and their headers:
<SyntaxHighlight lang="po" highlight="2,5">
msgid "Reconciled"
msgstr "Abgeglichen"
:
msgid "Reconciled:R"
msgstr "Reconciled:A"
</SyntaxHighlight>
* '''Sample text''' to determinate the size of the output cell. ''Instead of a translation'' the "worst case" of expected text in your language is required here.
:For the following example the german tranlators copied ''the longest path'' of account names from their business account templates as shown in the accounts tab of Gnucash: <SyntaxHighlight lang="po" highlight="2">
msgid "sample:Expenses:Automobile:Gasoline"
msgstr "sample:Aufwendungen 2/4:Reparatur/Instandhaltung:4805 Reparatur u. Instandh. von Anlagen/Maschinen u. Betriebs- u. Geschäftsausst."
</SyntaxHighlight>
:;Important: ''Keep'' the part before the colon ''untranslated''.

Another form - without need to insert the prefix - was <SyntaxHighlight lang="po">
#. Translators: This string has a context prefix; the translation
#. must only contain the part after the | character.
#: gnucash/gnome-utils/dialog-options.c:722
#: gnucash/gnome-utils/gnc-tree-view-account.c:908
msgid "Column letter for 'Placeholder'|P"
msgstr "P"
</SyntaxHighlight> and became
<SyntaxHighlight lang="po">
#: gnucash/gnome-utils/dialog-options.c:719
#: gnucash/gnome-utils/gnc-tree-view-account.c:906
msgctxt "Column header for 'Placeholder'"
msgid "P"
msgstr "P"
</SyntaxHighlight>
;Tip: A tool like kdiff3 can help you to recover your previous translation.
====== Message Context ======
In more recently written parts we use a message context: <SyntaxHighlight lang="po" highlight="2-3">
#: libgnucash/app-utils/gnc-ui-util.c:903
msgctxt "Reconciled flag 'not cleared'"
msgid "n"
msgstr ""
</SyntaxHighlight>

===== Special characters and other tips =====
''Depending on the context'' a few characters have a special meaning and need some special treatment:
;"#" (hash): In English it is often used as abbreviation for "Number". You should replace it by "No.", "Nr." or whatever is common in your language.
;"_" (underline): In ''menu and dialog entries'' the following character will become the '''accelerator''', '''mnemonic''' or '''hotkey''', which can be used together with a superkey [ctrl] or [alt] to jump to the entry. While in [[GTK2]] they have always been visible, in [[GTK3]] they appear only after holding the superkey. More specific under ''Linux'' you reach a main '''menu''' entry with <code>[alt]+[key]</code> and its submenus and other menu entries with <code>[key]</code>. In '''dialogs''' always use <code>[alt]+[key]</code>.
: The terminology is not unique here: while 
::[[#Desired|msgfmt]] has a <code>--check-accelerator</code> option and 
::DocBook uses <accel> tag for ''a letter used with a meta key'' and <shortcut> for ''a key combination'', but 
::GTK+ distinguishes the underline marked character of the label as ''mnemonic'' and the hotkeys like F1 for Help as ''accelerator''.
: So the key should be ''unique in its context'' and you should control it by [[#Running GnuCash]] with your file after [[#Compile & Install]]. See also (probably on your language) [https://developer.gnome.org/hig/stable/keyboard-input.html Gnome's HIG about keyboard input].
::''wrong:''
:::"do _this" # Hotkey: t
:::"do _that" #  Hotkey: t => not directly reachable 
::''right:''
::: "do th_is" # Hotkey: i
:::"do th_at" # Hotkey: a
::That is one of the reasons why you should [[#Optional Compile & Install|run the program with your translation]]: to see duplicate accelerators.
::;Characters to avoid: 
:::Already used on buttons like in English: '''C'''lose, '''H'''elp. Others depend on the context.
:::Characters breaking the baseline like in latin script: '''j''','''p''','''q''','''y'''. At least in some fonts the underline becomes invisible - leaving the user clueless.
:;In the headers of exported files: here it is used to link multiple words to one identifier together. Example:
<syntaxhighlight lang="po">
#: ../src/import-export/csv-exp/csv-tree-export.c:155
msgid "full_name"
msgstr "Vollständige_Bezeichnung"
</syntaxhighlight>

;"\" (backslash): It is the escape character in many programming languags. The following character has a special meaning like e.g.:
:;"\n" (New line): The most often used special character in our strings. If msgid contains "\n" keep the layout and add them to msgstr too - at the same places.
:;"some \"quoted\" text": Because " terminates the messages, you must precede it by a backslash inside of the messages or use other quoting characters like:
::*"some 'quoted' text"
::*"some »quoted« text"
::*"some „quoted” text"
::You are free to use the conventions which are common or suggested in your language, but stay consistent. For that purpose you should add a translator comment about the convention at the beginning of the file for better cooperation.
:Use <tt>"\\"</tt> to print a backslash.
;"%" (percent): In C based programming languages "%" marks the beginning of a '''format specifier''', e.g. "%d6" means insert the next variable here ''in decimal format with 6 digits''. Such format specifiers should be copied into your translated message, at the appropriate spot for your language, see {{URL:Boost}}doc/libs/release/doc/html/date_time/date_time_io.html#date_time.format_flags Boost's list of format flags for date and time].
:;Non-ASCII digits: As a special feature for Farsi (Persian) and maybe Arabic, translators can insert an ‘I’ flag into numeric format directives. For example, the translation of "%d" can be "%Id". The effect of this flag, on systems with GNU libc, is that in the output, the ASCII digits are replaced with the ‘outdigits’ defined in the LC_CTYPE locale category. On other systems, the gettext function removes this flag, so that it has no effect. 
:;Note: If a string is marked with c-format and has a % mark that does '''not''' start a format specifier, [{{BugURL}}/enter_bug.cgi?product=GnuCash&component=Translations file a bugreport] and tell the developers the location of the string (the lines above the msgid). The developers should fix this in the code. One way to do so is to insert a comment containing '''<tt>xgettext:no-c-format</tt>''' before the gettect call.
::In order to continue without having to wait for the developers' fix to propagate you can remove the <tt>c-format</tt> flag from the <tt>#,</tt> comment line above. If no other flags are in the line, simply remove the line.
:* To output "%" if a string contains format specifiers, use "%%" in your string.
:;Reordering parameters: Assume a string <tt>"In %d cases the result will be %d."</tt>, but in your language you would prefer to write <tt>"%d will be the result in %d cases."</tt> Now you would get the wrong numbers.
::;Solution: Insert the ordinal number of the parameter, followed by "$" in the format specifier: <tt>"%2$d will be the result in %1$d cases."</tt>.
;"~" (tilde): like "%", but for <code>scheme-format</code>. The basic scheme-format uses ~a or ~s to format subsequent variables within code and should be copied in the translated message, in the same order. Guile's <tt>(ice-9 format)</tt><ref>{{URL:guile-manual}}Formatted-Output.html</ref> does reordering with the ~@* and ~#* arguments, but it's a bit tricky to use:<syntaxhighlight lang="scheme">
  (format #t "~@*1~a's ~@* from ~@*2~a to ~a" "Balance Sheet" "Yoyodyne Pty" "1 Oct 2018" "30 Sept 2019")
</syntaxhighlight> would print <syntaxhighlight lang="console">
  Yoyodyne Pty's Balance Sheet from 1 Oct 2018 to 30 Sept 2019
</syntaxhighlight>
:;Note: ~a will insert a contents using "human readable" <tt>(display var)</tt> whereas ~s will insert contents using <tt>(write var)</tt>. This is an important difference which means ~a and ~s cannot be interchanged.<ref>{{URL:guile-manual}}Scheme-Write.html</ref>
<References />
;"{''num'',''optional other specifiers''}": this is a format specifier for C++ code. You cat either copy it verbatim somewhere in your translated message or you may [{{URL:Boost}}doc/libs/release/doc/html/date_time/date_time_io.html#date_time.format_flagsdoc/libs/release/libs/locale/doc/html/localized_text_formatting.html adapt it to your language].
;"&" (ampersand): is the starting  character of [{{URL:wp}}Character_encodings_in_HTML HTML encoding], which is used in some reports. E.g. <syntaxhighlight lang="html">&nbsp;</syntaxhighlight> means NonBreakableSpace.
;"<" (less): is the starting  charcter of tags in several markup languages.  E.g. <syntaxhighlight lang="html"><b>Text</b></syntaxhighlight> results in bold '''Text'''.
;See also: [[GUI Guidelines]] is the related programmers view.

===== Almost Done =====
If you are almost done it becomes harder to find the last untranslated messages. Then you can use <syntaxhighlight lang="sh">
msgattrib --untranslated ${LL}.po
</syntaxhighlight> and then search your file for the content of the msgid.

==== Check syntax and statistics of your .po file ====
===== Required =====
<syntaxhighlight lang="sh">
msgfmt -c --statistics ${LL}.po
</syntaxhighlight>
If that program reports one or more ''fatal errors'' for your language, you should review the criticized lines of your file.
:;Tip: A successful call will create a file <tt>messages.mo</tt>. If you are not using a build environment, you can move that file to
::;Linux: <tt>[[Building On Linux#Locations to which GnuCash may be installed|${PREFIX}]]/share/locale/${LL}/LC_MESSAGES/gnucash.mo</tt>
:: and restart gnucash to test the program with your translation.
===== Desired =====
In a second run you might wish to see, where you forgot to add an [[#Special characters and other tips|accelerator]]:
<syntaxhighlight lang="sh">
msgfmt -c --check-accelerators="_" --statistics ${LL}.po
</syntaxhighlight>
The users will love you if you fix them, too.

==== Current status ====
See [[Translation Status]] for the current status of the project with respect to translation contributions.

To see some over all statistics how many strings are translated, you can run
 for i in *.po; do echo -n "$i:"; msgfmt -c --statistics $i;done
in your po directory.

==== Priority ====
As you might have noticed, the po file for GnuCash is rather big by containing more than 4000 strings. It is somewhat helpful to look into different priorities for the different strings there. However, unfortunately the po file format doesn't enable any easy way for the GnuCash project to make the import strings differently from the less important ones. However, for a few files the developer team can give you some guidelines for the general priorities.

The ''source code location'' aka [[#Record Format|ref[erence]]] of a string gives you some hint about its priority. In particular, the following file suffixes or file locations imply a certain priority:
* '''High Priority:''' Strings from all '''*.glade''' files will be presented by the GnuCash user interface (UI) somewhere for the user. This may imply a somewhat higher priority to those strings - however, some UI elements are rarely used, so the actual location of the .glade file has an influence as well, but there isn't an easy rule for that anymore.
:;Tip: If you wish to see the string from a *.glade file in it's context, but don't know, where it is hidden in gnucash, if
::* the gnucash source files and
::* the Gnome's interface builder [https://glade.gnome.org/ Glade]
::are installed on your system, you can preview them for instance with <syntaxhighlight lang="sh">
LANG=C glade-previewer -f ${SOURCEDIR}/gnucash/gtkbuilder/${FILENAME}
</syntaxhighlight><ref>Without <tt>LANG=C</tt> you would see localized standard buttons, but for now you want to see everything in US English.</ref>
* '''Low Priority:''' Strings from all '''*.schemas.h''' files will '''not''' appear in the gnucash UI. Instead, they are shown only inside the 
:* Linux: ''dconf-editor'',
:* {{Mac}}: ''defaults'' or
:* Windows: ''regedit'' program when the user wants to set particular [[Glossary#G|GSettings]] keys of GnuCash. You can safely consider the .schemas.h strings with lower priority than the others.
**  '''Register2 feature''' is a stalled developement. The strings are only visible, if you [[#configure]]<tt> --enable-register2</tt>. Some, but not all strings are marked with a "Register2 feature" comment.

Unfortunately, there is no such simple rule for strings from *.c files or the single large intl-scm/guile-string.c file. The strings from there may be of higher or lower priority, but this isn't easily visible. We can only recommend to start GnuCash on your own with your updated translation, and then check for strings which you see but are not yet translated. Those are for sure of high priority.

Two additional source code locations can be noted as low priority:
* Everything from the file ''src/bin/gnucash-bin.c'' is of '''low priority''' because those are the command line options when running gnucash with different options from the command line. This is a use case that is performed only by highly experienced users which are accustomed to using the English-language command line commands. Therefore, translations here are of lower priority.
* Everything from the folder ''src/tax'' or from the intl-scm/guile-string.c file with a comment indicating some file in ''src/reports/locale-specific'' is related to tax preparation in the U.S. or in Germany. Hence, those strings are uninteresting for anyone living in different countries, and you can safely consider those with very '''low priority'''.

=== Testing and submitting your translations ===

You must check that your new translations are programatically correct (ie: 
that there are no unclosed quotes, etc).  To do this, use the msgfmt program

 msgfmt -c --statistics LL.po

Above call will report most important errors in your .po file and ''must not fail'', while the call below
 msgfmt -c --check-accelerators="_" --statistics LL.po
whill additionally check if you missed some keyboard accellerators aka hotkeys.

;Note for developers: Another python based tool is '''i18nspector''' - checking tool for gettext POT, PO and MO files. It is stricter and shows also warnings about expected entries which our .pot file is currently missing. That can be discussed e.g. in [[#Background]].

If you want to see your translations within a running version of gnucash,
simply place your .po file in the po/ directory of your local gnucash repository (which
you have previously installed) and from within the po/ directory type (you
may need to be root to do this):

 make install

Now you can run gnucash with your new translations:

 LANG=XXXX /opt/gnucash-git/bin/gnucash

To review the schema strings you can use
:;since 2.6: dconf-editor
:;until 2.4: gconf-editor.


==== Alternative Way with Poedit ====

If you use Poedit while working on .po file, you would notice that it saves file in .mo format, the very format that GnuCash uses itself. So one would just need to copy this LL.mo file into appropriate subdirectory under /opt/gnucash-git:
  cp LL.mo /opt/gnucash-git/share/locale/LL/LC_MESSAGES/gnucash.mo

The only thing that needs to be changed here is LL which stands for your language code (ka Georgian, de German etc). The rest is as in above method:
 LANG=XXXX /opt/gnucash-git/bin/gnucash

=== Submitting ===
Only if
* you want to send your file to the Translation Project or
* it did not exist before and you want to send it via mailing list, create a gzipped version of it:
<SyntaxHighlight lang="sh">gzip XXXX.po</SyntaxHighlight>
:Do the same with your [[#The glossary file]].

In all other cases just push your commit ([[Git#Pull Requests]]) or upload the [[Git#Patches]] of the files.
There should be one commit/patch containing the noise as described in [[#Update an existing .po file]] and a second one containing your actual work.

Then follow [[#How to submit changes directly to GnuCash]].

Alternatively, you could submit the finished translation via the GNU Translation Project. See the instructions on {{URL:TP}} and the first section of this document about how to do that.

See [[Translation Status]] for the current status of the project with respect to translation contributions.

See also {{ListURL}}/pipermail/gnucash-devel/2009-January/024700.html [FIXME: obsolete?]

==== Committers ====
* Check in which branch the translation should be submitted: [[Translation_Status]]
* Did you get [[#The glossary file]], too?
* Ideally [[#Updating an existing .po file]]
* Checks:
**[[#Check_syntax_and_statistics_of_your_.po_file]]!
*:Notify the statistics for the commit message.
** The Python tool <tt>i18nspector</tt> finds many additional errors, particular bad header lines. But its language list is incomplete as it knows not many 3-letter-languages. 
**Some common mistakes:
::;msgid "translator-credits": should contain at least the "Last-Translator:" from the header.
::;msgid "gnucash-icon": do not translate, we have only one.

* If the language is ''new''
** [[#Adjust po/CMakeLists.txt]] already done?
** and not handled by the [[#translationproject.org]], they need a '''note about the external handling'''. Else it can happen e.g. as of 2015-03  {{URL:TP}}team/ar.html shows: <syntaxhighlight lang="console>
gnucash 	2.6.5 	0 / 4628
</syntaxhighlight>
::If you there click on 2.6.5 you will get a fresh gnucash-2.6.5.pot, while we have already an ar.po with 2031 translated and 4 fuzzy messages. By contrast on the as external marked {{URL:TP}}team/de.html, you see: <syntaxhighlight lang="console>
gnucash 	2.6.5 	unknown 	external
</syntaxhighlight>
::and will not get a new pot file.
::But we can bundle this notes with the release announcement, if you add the language to [[Release Process#TP Status changes]].
* On committing add the name and email address of the last translator from the file as author, e.g.
<syntaxhighlight lang="sh">
 git commit --author="Lieutenant Worf <lt.worf@starfleet.org>" --message="L10N:tlh[: optional status or other details]

4677 translated messages." # << The msgfmt statistics
</syntaxhighlight>
* If you check in a new language, remove a language or see the status of the language changes from partial to (almost) complete, update the numbers in ''<sect2 id="oview-featuresintl2">'' in file '''guide/C/ch_oview.xml''' of ''gnucash-docs''.

=== Problems===

==== Gtk-CRITICAL messages ====
'''Note:''' Fixing this problem is quite difficult. We keep the explanation here in case some developers need it in the future, but if you have no idea what we are talking about in the next sentences, you should rather ignore these Gtk-CRITICAL messages and our explanation here!

If you see any "Gtk-CRITICAL" messages while running gnucash, it is probably
because you translated a string differently than how it exists in some other
gnome library.  You must discover which string you translated differently, and
change the translation to exactly match that of the gnome libraries.

To do this, you need to run gnucash under gdb:

 LANG=XXXX /opt/gnucash-git/bin/gnucash-env gdb /usr/bin/guile

Then, from within gdb, issue:
 run -e main -s /opt/gnucash-git/libexec/gnucash/overrides/gnucash --g-fatal-warnings

Eventually, gnucash should crash (because of the --g-fatal-warnings 
directive), when it does, issue from within gdb:

 backtrace

You should see some output that looks like this:

 #0  0xffffe002 in ?? ()
 #1  0x42028a73 in abort () from /lib/tls/libc.so.6
 #2  0x4019d3d8 in g_logv () from /usr/lib/libglib-1.2.so.0
 #3  0x4019d414 in g_log () from /usr/lib/libglib-1.2.so.0
 #4  0x40500fdd in gtk_type_check_object_cast () from 
 /usr/lib/libgtk-1.2.so.0
 #5  0x407292e5 in gnc_mdi_tweak_menus (mc=0x825adb0) at gnc-mdi-utils.c:574
 #6  0x40729d13 in gnc_mdi_child_changed_cb (mdi=0x8266fd8, prev_child=0x0,
      data=0x8265fd8) at gnc-mdi-utils.c:861

Notice position #5 which has "gnc_mdi_tweak_menus at 
gnc-mdi-utils.c:574"?  Open that source file and find line 574:

 573:  widget = gnc_mdi_child_find_menu_item(mc, "_View/_Toolbar");
 574:  gtk_signal_handler_block_by_data(GTK_OBJECT(widget), info);

So, the problem is with the translation of "_View/_Toolbar".  The "/" is a 
menu seperator, so you now know that the problem is with either the 
translation of "_View" or "_Toolbar".  By switching to an English gnucash (LANG=C) 
and looking through your .po file, you should be able to find out the problem.
Change the offending translation to whatever you see in the gnucash app.
Remember that the translations must contain the proper underscores.

==== Watch File accesses ====
To follow gnucash as it access files, 
 strace /opt/gnucash-git/bin/gnucash

=== Thank You ===
Thanks so very much to all the translators for their hard effort and
excellent work.

== Check Files in Repo gnucash's doc Directory ==
;Note: The content of this directory got some cleanup by <s>[{{BugURL}}/show_bug.cgi?id=797111 bug 797111]</s>.

In theory one could create localized man pages (<command>.<man-section>[.in]). But their content is almost the same as <tt><command> --help</tt>, which are translated for <tt>gnucash</tt> and <tt>gnucash-cli</tt>.
;Task: We should use gettext also  in the perl modules.

* If you add files add them to <tt>set(doc_DATA ...)</tt> in [{{URL:GH}}Gnucash/gnucash/blob/maint/doc/CMakeLists.txt CMakeLists.txt].

== Translating the GnuCash Guide and Help==

This section describes the actions needed to translate the manuals. There are currently 2 parts:
* ''Tutorial and Concept '''Guide''''': This is an introduction in the basic principles of double entry accounting and their application in GnuCash. This text is really useful for new users. 
* '''Help''': This is the context sensitive help system. 

If you are interested in translating these documents, please decide whether you want ''only'' to translate the existing text or whether you want also to improve and cross-check the text with the actual status in the program in your language. It is less effort only to translate the text, but you also run into the risk of doing unnecessary work if you translate explanations which are no longer correct. It might be more effort to create a new text in your language, using the English text only as an inspiration, but it will surely lead to more useable and more helpful documentation. We, the programmers, encourage you to do the latter and create a new text in your language. As you are the one doing the work, the decision is up to you.

Both documents consist of 
* '''text''' files in an XML format called [{{URL:wp}}DocBook DocBook], where the complete document is split into a collection of xml files by chapter, and
* '''images''':
** In the few ''scalable vector graphics'' (SVG) you can replace the text in you localized file.
** But most are ''screenshots'' stored as [{{URL:wp}}Portable_Network_Graphics Portable Network Graphics] (png) files in the subdirectory figures/. The xml files will contain links to the png files where they should appear in the text.
:;See also: [[Documentation Update Instructions#Screenshots And Other Images]]
At the beginning you might wish to concentrate on the text. If desired, you could link the english pictures from <tt>C/figures</tt>.

You can find an introduction to DocBook in [{{URL:dbk-tdg}}ch02.html Creating DocBook Documents].

Please use a ''unified terminology'': The translator of the program messages should have created [[#The glossary file]] for the translations of the key wordings in the program. Please make sure to use the same terms in the documents, too.

You can check the [{{BuildURL}}/docs/ nightly builds] - in particular after your updates were committed.

=== Prerequisites ===

==== Linux ====

In addition to the software for running autogen.sh, the following additional software is needed for the development on Linux. From the [{{URL:GH}}Gnucash/gnucash-docs/blob/maint/README gnucash-docs/README] file as of 2019-02-19:

:* libxml2
:* libxslt [Debian packed the required xsltproc in a separate package, 
::          which depends on libxslt]
:* docbook-xsl
:* rarian or
:: scrollkeeper >=0.3.4 (its ancestor)
:* yelp (for viewing)

:Optional:
:* gnome-doc-utils (contains <tt>xml2po</tt> for the use of po editors like in the it translation)

:Additional Requirements for Generating Mobipocket:
:* Calibre (https://www.calibre-ebook.com/)

:Additional Requirements for Generating chm:
:* Mingw (http://www.mingw.org)
:* Html Help Workshop ({{URL:MS}}en-us/download/details.aspx?id=21138 for Win XP - 8)

:Additional Requirements for Generating PDF:
:* Apache fop  >= 0.95
:For the Japanese PDF, Japanese fonts are included. If you want to use other Japanese fonts you can use the --with-japanese-fonts-dir, --with-japanese-mincho-ttf, and --with-japanese-gothic-ttf configure options to select them. fop's TTFReader can't, as of version 1.1 anyway, handle OpenType fonts.

'''Note for wiki editors:''' Keep above section in sync with [{{URL:GH}}Gnucash/gnucash-docs/blob/maint/README gnucash-docs/README]

==== Other Operating Systems ====

Wm says the section below is being edited and not yet complete, see the thread "Help with help" in gnucash-devel for more info
----

===== {{Mac}} =====

At present we do not know of a suitable DocBook file toolset for ''{{Mac}}'' though a *nix on Mac approach may / should work.  We encourage solutions so if someone could document this we would be grateful [Wm: aside is this redundant? Don't most modern Macs include *nix so instructions similar to those I have provided for Win might apply?]

===== Windows =====

One way of being able to edit and produce DocBook files on ''Windows'' is to use the *nix instructions under cygwin.  Instructions for obtaining a suitable toolset follow

*Get cygwin by going to https://www.cygwin.com and pressing the link for the setup-*.exe file suited to your system
*save it, virus scan it, etc. as you see fit then run it
*type "libxslt" into the search box
*expand Libs and press Skip so that it shows a version for all 3 GNOME XSLT Library options, you want the most recent which it will offer by default, cygwin will work out the gndependencies
*you may follow similar steps to obtain git, i.e. type "git" into the search box, expand and tick the obvious candidates
*Note: because these are *nix type text based utilities you are downloading hundreds of kiloBytes not megaBytes; relax, this isn't Windows Update, a few extra progs won't kill your system, promise
*click next at the bottom rhs and let cygwin do its stuff; this may take some time depending on connection speeds at both ends
*Aside: if you get a msg about "Package: Unknown package / inetutils.sh exit code 1" you may ignore it, after reading the full blurb, of course, my advice is not to try and track it down unless you have a lot of spare time on your hands
*When it is done fire up cygwin and do stuff as per the *nix instructions

Further details:

*don't look for
:*yelp (the viewer)
*on cygwin: it isn't there; it is an old prog (last updated in 2007, I think
:: wrong, see https://download.gnome.org/sources/yelp/ for the origin and https://cygwin.com/packages/summary/yelp.html for cygwin. --[[User:Fell|Fell]] 17:21, 26 October 2013 (EDT)
:) and should probably not be regarded as current though it may be useful if you have it on another OS
: [Wm: 
::* I wonder how many current *nix users have it?
::: AFAIK it is still part of the GNOME desktop: [https://www.google.de/search?q=yelp+gnome google search for yelp+gnome] --[[User:Fell|Fell]] 17:21, 26 October 2013 (EDT)
: Should ref to yelp be made less prominent?
:: It is the only way I know to get some context sensitive help from inside GnuCash. --[[User:Fell|Fell]] 17:21, 26 October 2013 (EDT) 
: ]

Wm says the section above is being edited and not yet complete, see the thread "Help with help" in gnucash-devel for more info

===== Java (all OS) =====

[[Eclipse]] has 
* several Git plugins,
* a C Development Tool with autotools support,
* a feature rich, builtin XML editor and a few plugins like XML WYSIWYG editors
or in other words, all what is needed here, available.

=== The Procedure ===

First, you have to download the most recent version of the gnucash-docs package. This is done as follows:

# Checkout the documentation in a directory ''gnucash-docs'':
#: <code>git clone <nowiki>{{URL:GH}}Gnucash/gnucash-docs</nowiki> -b maint gnucash-docs</code>
# Create your working branch. If you plan to use pull requests, you should use unique names like ''guide-LL-chapter-x-part-n'' instead of working-branch.
#: <code>git checkout -b working-branch</code>
# Create a new directory (if it doesn't already exist) in guide/<locale> where <locale> is of the form <language>[_<region>] e.g. es, en_GB, or pt_PT. See [[#Naming Conventions]].
#:See [[Locale_Settings#IETF_language_tags]] for details.
#:If your translation is the first for your language do not add a region code. So also other regions benefit from your translation.
#:And copy the files from guide/C into this directory:
#: <code>cp -r guide/C guide/LL</code>
#:;Not in latin letters written languages: They need additinal files to process printing to pdf. See <code>ja</code> or <code>ru</code> as examples.
# Add the directory you created to [gnucash-docs/]'''configure.ac''' (as a new line ''guide/<language>[_<region>]/Makefile'' under AC_OUTPUT) and [gnucash-docs/]guide/Makefile.am (at the end of SUBDIRS).
# Notify git about the new directory and files. "*" is quoted by "\".
#: <code>git add guide/LL/\*.\*</code>
# Now the real work: 
## Edit '''all the xml files''' (see [[#DocBook xml editors]] below for suitable editor programs) and translate them into your language.
##* In the event the english documents get updated, it might be useful to have a comment in the header of each chapter in  the form:
##: <syntaxhighlight lang="xml"><!-- Translation based on maint/master commit 1234567 2014-01-01 10:00 UTC --></syntaxhighlight>
##: Then you can later view a diff between the current and that version of the english file in one window to locate the changes and adjust the translation in  another window. Some translators like to do also the translation in a graphical diff program like KDiff3 between english and their language because the <code><sectN id></code>s will synchronize the text.
##* Use the same terminoloy as in [[#The_glossary_file]]. If you did not [[#Get_the_source_from_Git]], you can simply download your languages .po file from the [{{URL:GH}}Gnucash/gnucash/tree/maint/po/glossary glossary directory at GitHub].
## Adjust  '''<tt>gnucash-{guide|help}-<lang>.omf</tt>'''. This file follows [https://www.ibiblio.org/osrt/omf/ Open Metadata Framework] (OMF), a subset of the [https://dublincore.org/ Dublin Core] description for metadata. See [http://scrollkeeper.sourceforge.net/documentation/writing_scrollkeeper_omf_files/index.html Writing ScrollKeeper OMF Files] for details like mandatory standard elements. Without this file your document will not show up in ''yelp''s index page. At some point in the future we might extract this data automaticly from the docs using  [[Gnome Doc Utils]].
##: Currently it is also necessary to replace in <tt>{guide|help}/<lang>/Makefile.am</tt> the "C" in both occurrences of <tt>$(docname)-C.omf</tt> by <lang>.
## There are some general headers, which do not appear in the xml-files in your locale directory. But they can be translated by adding ''a section in '''xsl/l10n.xml'''''. Obey the comment at the beginning. If you use non-ASCII characters, you should run <code>recode -d <input_encoding>..h0 l10n.xml</code>, where input_encoding might be u8 for UTF8, to get them right encoded.
## In addition to the text, you need to ''recreate the image files in '''guide/C/figures''''' so that they are appropriate to your language. For details (size, style,...) see [[Documentation_Update_Instructions#Screenshots And Other Images]].
### Most of them are '''screenshots''' of a gnucash session - save them as png files because this will use a lossless compression. In theory some of the files in gnucash/doc/examples could be a starting point therefor, but they are currently - 2010-09-17 - broken.
### A few figures are in '''scalable vector graphic''' (svg) format. Here you can edit the files e.g. in ''Libre/OpenOffice'' and translate the strings and adjust the size.
## Watch out: The documentation itself is ''probably outdated in many places'', as it has been written for the 1.8.0 version of gnucash. You can watch the current progress in [[Concept_Guide#Ongoing_work]]. If you encounter any description that is wrong for the current version of gnucash, do not hesitate to ignore the english original text and instead describe the situation of the current version of gnucash in your translation. It would be even better if you have the time to change the english original text as well, or at least ''file a bug against it'', but even if you can't do that, feel free to describe the actual state of gnucash in your translation and simply ignore the original english text.
##: If you file a patch against the english text, you can also file a patch, which adds your name and email address to AUTHORS, so you will become famous. ;-) Ask to apply this latter patch also against gnucash/DOCUMENTERS because both files should have the same content. More details about editing the english text can be found in the [[Documentation Update Instructions]]. 
# Test your xml files for syntax errors by running ''xmllint'' on the '''main file''' ''gnucash-{guide|help}.xml'', e.g.:
#: <code>xmllint --valid --noout gnucash-guide.xml</code>
#: The program ''xmllint'' is part of the package '''libxml'''.
#: '''Tip:''' Some ''xml aware editors'' have a menu entry like ''validate'' to run this test. 
# Optional: test your work with yelp - there are build system methods to support you. The exact steps differ based on the build system you choose:
## Using a terminal, go to your gnucash-docs directory<SyntaxHighlight lang="sh">
cd /path/to/gnucash-docs # replace the example path with your real path
</SyntaxHighlight>
## Make a build directory and go into it<SyntaxHighlight lang="sh">
mkdir build
</SyntaxHighlight>
## Setup a build system of choice<SyntaxHighlight lang="sh">
# Run this for the autotools based build system (deprecated!)
./autogen.sh
cd build
../configure --PREFIX=../install
# Or run this for the cmake based build system (preferred)
cd build
cmake -D CMAKE_INSTALL_PREFIX=../install
</SyntaxHighlight>
##: There are plenty of other options you can pass to either configure or cmake, but that's outside of the scope of this wiki page.
#: The steps above only have to be run once (though running it more than once is safe). What follows can be repeated as often as needed while working on the docs.
## To check your work while editing you can run<SyntaxHighlight lang="sh">
make check
</SyntaxHighlight> in the build directory. That will However check ''all'' documentation, not just the one you're working on.
## If you want to check only your work a different command is needed depending on your build system. Each command starts from the top-level of the build directory and in this example we will check work on the German version of the guide:<SyntaxHighlight lang="sh">
# Run this for the autotools based build system (deprecated!)
(cd guide/de && make check)
# Or run this for the cmake based build system (preferred)
make de-gnucash-guide-check
</SyntaxHighlight> This will run the <code>xmllint</code> command above over the full directory structure. As an aside you can generate the documentation in other formats, like pdf or html by replacing ''check'' in the commands above with ''pdf'' or ''html'' respectively:<SyntaxHighlight lang="sh">
# Run this for the autotools based build system (deprecated!)
(cd guide/de && make pdf)
# Or run this for the cmake based build system (preferred)
make de-gnucash-guide-pdf
</SyntaxHighlight>
## In order to be able to see your work in yelp you still have to install it. From the build directory run:<SyntaxHighlight lang="sh">
make install
</SyntaxHighlight>
## To see your work in yelp use the following command<SyntaxHighlight lang="sh">
# In the command below, replace
# <language> with the language of the doc you want to view, for example C (for English), de (for German),...
# /path/to/gnucash-docs with the real path to the source directory for your documentation
# <docname> with the document you wish to view, either gnucash-help or gnucash-guide
LANG=<language> XDG_DATA_DIRS=/path/to/gnucash-docs/install/share:${XDG_DATA_DIRS}:/usr/local/share:/usr/share yelp gnome-help:<docname>
# Example:
LANG=pt XDG_DATA_DIRS=/path/to/gnucash-docs/install/share:${XDG_DATA_DIRS}:/usr/local/share:/usr/share yelp gnome-help:gnucash-guide
</SyntaxHighlight>This uses yelp's built-in mechanism to select the proper language.
## Alternatively you can open the installed document directly via:<SyntaxHighlight lang="sh">
yelp /path/to/gnucash-docs/install/share/gnome/help/<docname>/<language>/<docname>.xml
</SyntaxHighlight>You need to make the same replacements as in the other form.
## Repeat these steps until you're satisfied with the result.
# Update the branches of your local repo often:
#:<code> git checkout maint              # switch to maint</code>
#:<code> git pull --rebase               # update it</code>
#:<code> git rebase maint working-branch # update working-branch</code>
#:<code> git checkout working-branch     # switch back to working-branch</code>
# Follow [[#Submitting your work direct to GnuCash]].

To translate the help files, repeat steps 2-10 but replace the "guide"
directory with "help".

'''Committers:''' If it builds fine, add the directory changes from 2. also to <tt>gnucash/maint/packaging/win32/install-impl.sh</tt> and merge the change to master, if required.

=== DocBook xml editors ===

For editing these DocBook xml files, various editors can be used: {{URL:wp}}DocBook might contain pointers to some, or also https://www.tldp.org/LDP/LDP-Author-Guide/html/tools-edit.html.
:Some developers use [[Eclipse]].
:The [[{{URL:wp-de}}OmegaT german wikipedia] says the translation tool [https://omegat.org/ OmegaT] can work on docbook.

People have said that AbiWord and OpenOffice / LibreOffice have support for DocBook available, in which case you could directly edit gnucash's xml files with those. However, those editors will probably not work with the current multi-file setup where each chapter is in a separate XML file and the main XML file contains points to the chapters' files. As a workaround, you can copy the relevant parts of the main XML file into the chapter's file by a plain text editor so that it "looks like" one single DocBook document. This can be opened with OpenOffice/LibreOffice and edited as normal. After that, the added parts from the main file need to be removed again, and then you have the edited chapter text.

=== Using po editors ===

Some translators are more familiar with using po file editors like poedit, Kbabel, Gtranslator etc. For those people, it is possible to convert the content of the help documents (the DocBook XML files) into po files, translate the messages in the po file, and convert the result back into xml. This section describes how to use this approach for the gnucash help documents.

;The downside of this approach: It will be much harder for the documenters to fix e.g. broken links in times where you are inactive.

In order to use po files you have first to convert xml files to po files, translate them and then convert back to xml.

First you have to install a fresh version of gnome-doc-utils. For example in a Fedora 13 system
 <code> yum install gnome-doc-utils</code>.

#Do the conversion with the following commands (xx is your language code, example: el for Greek): 
#: <code>xml2po -o helpfile.xml.pot helpfile.xml</code>
#: <code>mv helpfile.xml.pot helpfile.xml.xx.po</code>
#Translate helpfile.xml.xx.po using your favorite po editor.
#Convert back to xml:
#: <code>xml2po -e -p helpfile.xml.xx.po -o xx_helpfile.xml helpfile.xml</code>
#Test your translated xml file as mention above:
#: <code>xmllint --valid --noout xx.helpfile.xml</code>
#Remove xx from xx_helpfile.xml and you are ready to commit it in your language help directory

=== Workaround for the broken OpenSuse help system ===

As in OpenSuse 10.x and 11.x the help system is broken, there is a workaround, to review the result of your work. Locate gnucash-guide.xml in your system, probably /usr/local/share/gnome/help/gnucash/C. Then from that directory do 

 xmlto -o /path-to-where-you-want-to-store-docs/ html gnucash-guide.xml

which will make an html copy of the docs.

Copy over the 'figures' directory with contents to your html directory above
and set a bookmark in browser to the index.html so that you get the docs
any time you need them. The context sensitive facility is lost, but for
general reading it works.[{{ListURL}}/pipermail/gnucash-user/2008-September/026699.html]

=== GnuCash Maintainer Tasks ===
For new languages the core developers have some additional tasks:

==== New Script ====
Check <code>make pdf</code>! Do we need additional TTFs?

==== First Nightly ====
Ask the admin of {{BuildServer}} to create the new directory.

==== First Release ====
Adjust htdocs ...

== How to translate the files containing the new account hierarchies==

This section describes the actions needed to translate the files
containing the new account hierarchies.

=== Preliminary Considerations ===
:However, please take a moment to think about the intention of the account hierarchy templates. The intention of those files is much more language-related than any other of the files inside gnucash. A string-by-string translation is not the best thing to do here. Instead, you can and should find out an actual recommended account structure which makes sense in your language, and implement that one in your language. By this, I mean several of the english accounts make sense only in the U.S., but probably not in other countries. Hence, your translated account template should not contain them. Also, you can add additional parts of the account templates for your language as well, if the users are likely to need it. 

:For example, in the U.S., users are likely to own a car, and for this reason there is an account structure template for "Car". If in another hypothetical region users are likely to own, say, a spaceship instead of a car, you should remove the "Car" template and instead create a new account structure that represents all accounts related to the ownership of a spaceship, and offer this as additional "Spaceship" template.

:In other words, you should feel free to create a completely new account template structure that is most suited to your language. The english-language templates are just a proposal, but will need further adaption and not a string-by-string translation.

Having said that, here is how you would start for a direct translation of the English templates:

In this section always replace <tt><locale></tt> with your [[#Naming Convention|language code]] and ''optional'' your region code, if there are multiple countries with the same language and your templates are fitting only to one of them.

=== Prerequisite ===
* If not done before, [[#Get the source from Git]].

=== Initialize accounts/<locale> ===
* If it does not already exists, execute the following steps to initialize your <tt>accounts/<locale></tt> directory:
# Copy the directory <tt>accounts/C</tt> to <tt>accounts/<locale></tt>
# In the directory <tt>accounts/</tt> change the file CMakeLists.txt and add your <locale> to both alphabetical sorted lists:
## <syntaxhighlight lang="CMake">
add_subdirectory(C)
:
add_subdirectory(<locale>)
:</syntaxhighlight>
## <syntaxhighlight lang="CMake">set(accounts_DIST ${C_DIST} ...  ${<locale>_DIST} ... ${dist_list} PARENT_SCOPE)</syntaxhighlight>
# In <tt>accounts/<locale>/CMakeLists.txt</tt> adjust the <locale>:<syntaxhighlight lang="CMake">
:
set_dist_list(<locale>_DIST ${dist_account_DATA} CMakeLists.txt)

install(FILES ${dist_account_DATA} DESTINATION ${ACCOUNTS_INSTALL_DIR}/<locale>)
file(COPY ${dist_account_DATA} DESTINATION ${ACCOUNTS_BUILD_DIR}/<locale>)
</syntaxhighlight>
#;Note: The next 2 steps are are discussed in [[#Localize the Account Charts]] below.
# Localize <tt>acctchrt_full.gnucash-xea</tt>. This is only a helper file where you have all accounts in their context.
# Now create the real modules by merging the respective parts from <tt>acctchrt_full.gnucash-xe</tt> in the other acctchrt_*.gnucash-xea files.
* If you remove or create new files, adjust in <tt>accounts/<locale>/CMakeLists.txt</tt> the list<syntaxhighlight lang="CMake">
set(dist_account_DATA
  ...)
</syntaxhighlight>
* Whenever you changed one or more <tt>CMakeLists.txt</tt> files, you have to rerun <syntaxhighlight lang="sh">
cd ${SOURCEDIR}
cmake <your options>
cd ${BUILDDIR} # e.g. .build
make # or ninja</syntaxhighlight>

=== Localize the Account Charts ===
'''Tip:''' <tt>C/acctchrt_full.gnucash-xea</tt> is a helper file. Because we prefer modularization it usually is not part of the distribution. It contains the full tree of the ''personal en_US accounts''. The other <tt>acctchrt_*.gnucash-xea</tt> files contain single branches of that. So after translating it you can copy&paste the respective parts in the other files to ensure consistency between them.

If you modularize the templates you should start with <tt>acctchrt_common.gnucash-xea</tt> - it is the most basic.

For each ''desired'' <tt>acctchrt_*</tt> file in that directory:
# Change the <tt>gnc-act:title</tt>, <tt>gnc-act:short-description</tt>, and <tt>gnc-act:long-description</tt> to contain appropriately translated text. Do not add any newlines in the long description except at the end and begining of the string.
# For each <tt>gnc:account</tt> in the file
## translate the <tt>act:name</tt>, and <tt>act:description</tt> fields.
## Optionally you can
### assign an '''account number''' <tt><act:code>1234</act:code></tt> after <tt><act:commodity-scu></tt> or
### add a '''note''' as i.e. in <syntaxhighlight lang="xml" highlight="6-9">   <act:slots>
    <slot>
      <slot:key>hidden</slot:key>
      <slot:value type="string">true</slot:value>
    </slot>
    <slot>
      <slot:key>notes</slot:key>
      <slot:value type="string">Some additional text about the usage of this account</slot:value>
    </slot>
    <slot>
      <slot:key>placeholder</slot:key>
      <slot:value type="string">true</slot:value>
    </slot>
  </act:slots>
</syntaxhighlight>
#:  Please do ''not translate'' any other fields or the internally used ROOT account.
# To avoid typos, run the [[Account Hierarchy Template#Syntax Check]].
# New files to be shown to the user must be added to the <tt>account_DATA</tt> section,
#:helper files like ''acctchrt_full.gnucash-xea'' to <tt>EXTRA_DIST</tt> in <tt>Makefile.am</tt>.

'''Note again:''' You absolutely don't need to translate all of the files from
<tt>accounts/C</tt>.  A subset of those are fine as well. Probably several of
them will not apply to your local legislative/economic system anyway.
For a really customized account hierarchy you might better create a
new account hierarchy file in GnuCash, and then, by hand-editing the
xml code, split it up into several files and cut&paste the appropriate
tags from the accounts/C/acctchrt_* files.

If you wish to add '''new accounts''' manually, you will need some additional ''guids'', those funny random numbers. To get them you can use:
<SyntaxHighlight lang="sh">uuidgen | sed -e 's/-//g'</SyntaxHighlight>
or use an online uuid generator like [https://www.guidgenerator.com/ this one] (any other one will do as well). Be sure to untick "Hyphens" to generate gnucash compatible guids. If you forget or the site you use doesn't offer that option, simply remove the hyphens yourself.
;Dependencies:''uuidgen'' is in a package ''''util-linux'''', '''sed''' has its own package. <!-- on opensuse; add different names for other distris -->

[[Account Hierarchy Template]] describes, how to create new templates e.g. for business purpose according local rules.

=== Test your Work ===
To test your work under real conditions, you should finally [[#Compile_.26_Install|Compile & Install]] it. But before you need an adjusted '''Makefile.am''' in your accounts/<locale> directory. If none exists, copy that from <tt>accounts/c</tt> and adjust it:
* 1. Line (accountdir): adjust the locale.
* If you removed accountcharts, remove their line from <tt>account_DATA</tt>,
* if you added new files, insert lines with their names and "\" (the line continuation symbol).

== How to create localized Income Tax Tables ==
;Note: This section is under developement and mostly untested!

As of the beginning of 2015 there is an nice US tax module with a report and export in TXF format.
Additional there is a small de_DE derivate for the monthly VAT declaration. you can compare them to see, how you can tweak them to get something else.

=== Tax Table ===
Because it is also used by <tt>Edit->Tax Report Options</tt>it is part of the [{{URL:GH}}Gnucash/gnucash/tree/maint/libgnucash/tax/ GnuCash library]:
# Copy <tt>us</tt> into a new subfolder with the lowercased  ISO code of your region.
#:It contains the following files
## tax.scm - is only a linking element, where you have to replace <tt>us</tt> by your region twice.
## txf.scm - the tables, and
## txf-help.scm - the descriptive help strings for each TXF code. This is also used to get a table in gnucash-docs/help/
#They have relative simple table structures: <syntaxhighlight lang="scm">
(define txf-tax-entity-types 
</syntaxhighlight>
#:contains a list of forms for different entities (person, company …). <syntaxhighlight lang="scm">
(define txf-income-categories …
(define txf-expense-categories …
</syntaxhighlight>
#: contain for each of the above lists the entries. If you compare this file with the respective files in <tt>de</tt>, you can see an example localization with additional categories: <syntaxhighlight lang="scm">
 (define txf-asset-categories …
 (define txf-liab-eq-categories …
</syntaxhighlight>
#: It should be possible to adapt the lists for your tax forms.

=== Report and Export===
Probably you need to have other export reports. That are in
{{URL:GH}}Gnucash/gnucash/tree/maint/gnucash/report/reports/locale-specific/us like
* txf-export.scm
* us.scm is unused
Here you might probably need some help from a programmer.

== How to translate the website ==
:;Note about OS: These instructions are written for linux. They will probably work on other unix-like systems as well, but not on Windows. On Windows you may be able to do this if you set up a linux-like environment (with cygwin or MinGW[-w64]), but that's untested so far. Please report your findings here.

* Get a checkout of {{URL:GH}}Gnucash/gnucash-htdocs
* Run the command <syntaxhighlight lang="sh">make pot</syntaxhighlight>
* Then depending on whether or not a translation for you language exists already (complete or not):
*;Existing translation:<br>Run the command <Syntaxhighlight lang="sh">
msgmerge --previous -U po/LL.po po/gnucash-htdocs.pot
</syntaxhighlight> where LL is your language code, see [[#Naming Convention]] above.
*:;Alternative: <syntaxhighlight lang="sh">make msgmerge</syntaxhighlight> will update ''all'' .po files
*;New translation:<br> In the po directory run 
*:;As translator: <syntaxhighlight lang=sh>msginit</syntaxhighlight> This will insert your name, email and locale settings into the new file. If that fails copy the newly created file po/gnucash-htdocs.pot to po/LL.po, where LL is your language code, see [[#Build a new .po file]] earlier. 
*:;As maintainer: <syntaxhighlight lang=sh># Set LL=<language code>
msginit --no-translator --locale=$LL</syntaxhighlight> This will create  a new file $LL.po without personal data. Continue with [[#Maintainers Task]].
* Translate the po/LL.po file as described in [[#Translating the .po file]].
*;Priority:
::;High: Startpage: {index|externals/*}.phtml
::;Low: sizing.phtml (outdated) search/templates/NMZ.* (unused)
::;Medium: the rest depends on you.
* Run <syntaxhighlight lang="sh">msgfmt -c --statistics po/LL.po</syntaxhighlight> to see your success.
* Optionally run <Syntaxhighlight lang="sh">recode -d <input_encoding>..h0 po/LL.po</Syntaxhighlight> to get special characters HTML quoted.
* Send your LL.po either as
** GitHub Pull Request or
** attachment of a Bugzilla enhancement request to the mainteiner team.

===Maintainers Task===
Moved to [[Language_Administration#Website]].

== Tips for Developers ==
This section moved to [[I18N]].

==Project Maintainers==
Moved to [[Language_Administration]].

== Background ==
This section was started to get some overview, '''work in progress!'''
Beyond it helped to get rid of the outdated [[#IntlTool]] in version 2.7.6.
For details see the [{{URL:Gnu}}software/gettext/manual/gettext.html GetText Manual].

=== Packages ===
In our build process we use beneath self written scripts the following packages:
* glib2-devel: glib-gettextize      
* gettext, probably broken in:
** -runtime: msgfmt, ...
** -tools: (autopoint), gettextize, msg*, xgettext, ...
** -runtime-tools-doc: manuals etc.
* (only up to 2.7.5) intltool: Intltool*

=== Our Build Process ===
This was the old (upto 2.6) autotools build process, which went through the following scripts:
 
====== autogen.sh ======
;Note: Autotools were only used up to 2.6 branch. 2.7 and later use [[CMake]] instead.
;glib-gettextize: helps to prepare a source package for being internationalized through gettext. It is a ''variant of the gettextize'' that ships with gettext. 
:glib-gettextize differs from gettextize in that it doesn't create an intl/ subdirectory and doesn't modify po/ChangeLog (note that newer versions of gettextize behave like this when called with the --no-changelog option).

»Note that on GNU systems, you ''don't need to link with libintl'' because the '''gettext library functions are already contained in GNU libc'''.« (glibc) [{{URL:Gnu}}software/gettext/manual/gettext.html#Overview]

====== configure.ac ======
* Sets
 ALL_LINGUAS= ...
In recent versions it can be substituted by LINGUAS files in the po directories. We should consider this to distinguish TP vs. GC maintained translations.
 GETTEXT_PACKAGE=gnucash
This is intltool style. Gettext uses PACKAGE=...
 AC_SUBST(GETTEXT_PACKAGE)
 AC_DEFINE_UNQUOTED(GETTEXT_PACKAGE, "$GETTEXT_PACKAGE",
    [GetText version number])

AM_GNU_GETTEXT_REQUIRE_VERSION|AM_GNU_GETTEXT_VERSION(x.yy.zz) can be used to require a version. We should use it to avoid ...
* TP expects > 0.11.
* gnulib expects >= 0.17
* RHEL7 offers 0.18.2 (RHEL6 0.17)
* Debian Stable offers 0.18.1 and in backport 0.19.3
* '''Glade2 msgctxt''' and Glade3 were implemented in 0.18.3 - July 2013
* '''GSettings''' and '''Desktop''' entries are implemented in 0.19 - June 2014
* and got bugfixes until Version 0.19.3 - October 2014
* '''Scheme''' format strings got a fix in 0.19.4 - December 2014
* '''AppData''' support: [https://lists.gnu.org/archive/html/info-gnu/2015-09/msg00003.html gettext-0.19.6 released] - 2015-09
* ? custom XML formats in 0.19.7
:<gjanssens> GtkUIManager files don't contain translatable strings as far as I know. They're not in POTFIILES.in either.
* at the time of our last update: [https://lists.gnu.org/archive/html/info-gnu/2016-06/msg00006.html gettext-0.19.8.1 released] - 2016-06
* [{{BugURL}}/show_bug.cgi?id=725296#c21 gjanssens sv->swedish patch for Windows] is in gettext 0.20. It is also the first version , which extracts <developer_name> from appdata.xml. [{{ListURL}}/logs/2020/01/15.html#T15:20:46 IRC log]
* recent: [https://lists.gnu.org/archive/html/info-gnu/2019-05/msg00011.html GNU gettext 0.20.1 released] - May 12, 2019

This setting then can be used by autoPoInt. Watch the caveaets from https://www.gnu.org/software/gnulib/manual/html_node/gettextize-and-autopoint.html:
: On the other hand, if your package is not as concerned with compliance to the latest standards, but instead favors development on stable environments, the steps are:
:# Determine the oldest version of gettext that you intend to support during development (at this time, gnulib recommends going no older than version 0.17). Run autopoint (not gettextize) to copy infrastructure into place (newer versions of gettext will install the older infrastructure that you requested).
:# Invoke gnulib-tool, and import the gettext-h module. # Fixme: Meaning?

:Regardless of which approach you used to get the infrastructure in place, the following steps must then be used to preserve that infrastructure (gnulib’s bootstrap script follows these rules):
:# When a script of yours run autopoint, invoke gnulib-tool afterwards.
:# When you invoke autoreconf after gnulib-tool, make sure to not invoke autopoint a second time, by setting the AUTOPOINT environment variable, like this:
::<pre>$ env AUTOPOINT=true autoreconf --install</pre>

 .potfiles:

====== make-gnucash-potfile.in ======
This is a self written perl script from the time as gettext had several issues. It creates '''po/potfiles.in''', the "list of files which contain translatable strings". This script is not used in a cmake based build environment for gnucash. As gnucash 2.7.4 and more recent is cmake only, this file has been removed starting from that release.

====== xgettext ======

;xgettext: Extract translatable strings from given input files. See --language for supported list:
:;--language=NAME: recognise the specified language ('''C''', '''C++''', ObjectiveC, PO, Shell, ''Python'', Lisp, EmacsLisp, librep, '''Scheme''', Smalltalk, Java, JavaProperties, C#, awk, YCP, Tcl, ''Perl'', PHP, GCC-source, NXStringTable, RST, '''Glade''', Lua, JavaScript, Vala, '''Desktop''') 
:Options, which we should check:
:;--copyright-holder=STRING: set copyright holder in output
:;--foreign-user: omit FSF copyright in output for foreign user
:;--msgid-bugs-address=EMAIL@ADDRESS: set report address for msgid bugs
