Announcing a new sub-project in gnucash: GUI in C++, Qt, CMake.

Cutecash. Easy to develop, easy to use

Announcing a new sub-project in gnucash: The non-GUI parts are re-used in the state they are, in the C language. This means the double-entry principles and all of the other achievments in the "engine" and xml-backend and eventually other backends can be re-used. But the GUI is rewritten completely new, from scratch, in C++ and using the Qt toolkit. Fun again. The build system is CMake because its configuration runs magnitudes faster. Fun again. And as a final bonus, for MS windows more compiler than before are supported, namely this whole new project can be compiled by MS Visual Studio as well.

Vision

This finance software will be developed with the following two goals:

1. Create the best possible user experience in a finance management software
2. Have the highest possible amount of fun during development

Because of this, design decisions during development will have to be measured firstly by the point of view of the user, and radically so. Which one out of many possible design options will give the best user experience? Which option will best fulfill the currently known user requirements? This option is what we will implement. No more, no less. In particular, we will radically ignore all requirements which are currently not yet known, or are not based on the user's point of view.

If this first measure still leaves multiple options to choose from, we will generously choose the option which promises the most fun during development for us, the developers.

If this second measure still leaves multiple options, we arbitrarily but boldly choose one option for now (like Wikipedia's "Be Bold") and move ahead. We might revise the decision later, but then, software has been rewritten many times already, so that's nothing uncommon or to be afraid of. We will just make the decision for now and move on.

Some of these thoughts have been inspired by the book "Getting Real" by 37signals, see http://gettingreal.37signals.com for an on-line copy.

Build Instructions

Linux

On Linux, install qt4 (>= 4.5.0) and CMake (>= 2.6.0), grab the gnucash sources from SVN, change into its top-level directory and run

mkdir build-cutecash
cd build-cutecash
cmake ..
make
./src/gnc/cutecash

The qt4 development package is called libqt4-dev on Debian-related distributions.

Windows / MSVC

The sub-project Cutecash can be developed with the Microsoft Visual Studio compiler (MSVC) as well. Visual Studio 2008 Express was tested, but others might work as well. However, the Cutecash project needs a large number of dependency libraries which are not built by MSVC, but by the Windows-Mingw compiler (gcc).

The recommended process goes as follows:

• Let the dependencies be build by the mingw installation process which is being used for the "normal" gnucash, explained here: Windows, in particular Windows#Instructions_for_an_.28almost.29_automated_build
• Once all of this is built, you start CMake from http://www.cmake.org. Select the top-level folder of the gnucash source code as source folder; select some new empty folder as build folder. Then click "Generate" and choose a "Visual Studio 2008 project". Subsequently, you will have to select some header file locations and library locations until CMake does not complain about anything anymore, but those have all been installed by the automatic build from Windows#Instructions_for_an_.28almost.29_automated_build
• Next, you open the MSVC2008 project file that was created by CMake, then build this project. The resulting executable can be run and built again and debugged and developed in the normal Visual Studio way.
