Skrooge

Skrooge is a personal finances manager for KDE4, aiming at being simple and intuitive. It allows you to keep track of your expenses and incomes, categorize them, and build reports of them. Learn more...

Skrooge is a part of KDE Extragear, in the Office module

This page is dedicated to developpers or advanced users who wish to have a deeper understanding of Skrooge.

Compiling

Before we start, please consider using a precompiled package for your distro. You should only be compiling yourself if there is no package yet for your distro, or if you want the latest version, directly from the developpers.

Get the Sources

First, you will need to get the Skrooge source code. There are two ways to do this.

Latest Release

You can download the archive file containing the source code, and extract its content using your favorite extraction tool, such as Ark.

Development Version

Skrooge code is stored in KDE's git system. It can be found in http://projects.kde.org/projects/extragear/office/skrooge

Dependencies

To be able to compile and run Skrooge, you will need some additional components

KDE4 Headers

Skrooge being a KDE4 application, it depends on many things in the KDE headers. You can get them from your distribution's packages (name usually contains KDE4+devel, KDE4+headers), or directly from KDE repositories.

QCA

Qt Cryptographic Architecture. Get it from your distribution packages.

libofx

A library to handle import for OFX files. Get it from your distribution packages.

Build & Install

Place yourself in the directory containing the source code, and create a directory named "build" (This is useful to segregate built files from the source code). Open a Konsole in this directory, and run the following commands (as a normal user) :

<syntaxhighlight lang="text"> mkdir build && cd build cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` make

(please note the backquotes in the cmake command, they are important...)

Then, with root privileges :

<syntaxhighlight lang="text"> make install

Uninstall

Tried Skrooge but didn't like it ? Sorry to hear this... You can uninstall it by running this command in the aforementionned "build" directory, with root privileges :

<syntaxhighlight lang="text"> make uninstall

Debugging

Trace activation

To activate traces, you need to export an environment variable in your console:

export SKGTRACE=XX

XX is the level of traces you want. It should be an integer between 0 and 20. The higher the number, the higher the quantity of information you get. 10 is good compromise.

Then, start Skrooge from this console. This will display a lot of information in your terminal, giving you hints as to what could be going wrong if you face issues.

Profiling

To activate the basic profiling mechanism included in Skrooge, you need to export an environment variable in your console:

export SKGTRACEPERFO=1

Once Skrooge is started from this console, you can find two new commands:

Restart profiling (CTRL+Pause) to initialize the profiling
Open profiling (ALT+Pause) to open the result of the profiling

Profiling results look like this:

method , nb call , millisecondes , average , min , max , own time , average own time 
SKGMainPanel::setNewTabContent-addTab , 1 , 38.26897848 , 38.26897848 , 38.26897848 , 38.26897848 , 25.6370585 , 25.6370585
SKGObjectModelBase::refresh , 2 , 8.741794825 , 4.370897412 , 0.9698964357 , 7.771898389 , 8.147958875 , 4.073979437 
SKGMainPanel::setNewTabContent , 1 , 49.36599612 , 49.36599612 , 49.36599612 , 49.36599612 , 3.772916079 , 3.772916079 
SKGOperationBoardWidget::SKGOperationBoardWidget , 1 , 3.179117203 , 3.179117203 , 3.179117203 , 3.179117203 , 2.963078141 , 2.963078141 
SKGMainPanel::onOpenContext , 1 , 50.43999612 , 50.43999612 , 50.43999612 , 50.43999612 , 1.074000001 , 1.074000001
...

Remark: If SKGTRACE is set then you will be able to find the execution time of each methods in traces.

To profile only sql instructions, you can export an environment variable in your console:

export SKGTRACESQL=XX

Only sql order with an execution time greater then XX ms will be displayed in console.

In the console, you will get something like:

executeSqliteOrder : SELECT t_name, t_TYPENLS, f_CURRENTAMOUNT, t_close from v_account_display WHERE (t_type='C' OR t_type='D' OR t_type='I' OR t_type='O') ORDER BY t_TYPENLS, t_name TIME='441 ms'
