Development Tricks

Background
This page shows a list of time-saving workflow tips for Devs who are developing for Scribus. Feel free to add your shortcuts

Minimize compile time by specifying preferred language

 * Reduce the number of files copied in the "make install" step by limiting the number of used languages to the minimum necessary. For this, add:
 * to your cmake command if you only want english language GUI.

Manually copying object file to binary directory

 * If you know that only a single object file has been written by "make" (as an example when you're modifying the source of a plugin), if you're on a slow computer you can speed up the compile/run/tweak cycle by manually copying the object file to the binary directory, instead of doing "make install"

Use all CPU cores

 * Use all the cores of your CPU to compile faster. That's the -j option. If you got 8 cores, use : 'make -j8' and 'make install -j8' and you will make lot faster.

Traces in the terminal
Whenever you need to understand what happens in the code, it's possible to output traces in to the terminal using  function :

Note: Don't forget to CLEAN YOU CODE before issuing a patch

Qt
Add your Qt related tricks below:
 * Qt Creator is a powerfull IDE.
 * Check out QtCreator - workflow for Scribus and Git repos under Linux

Coding standards
Please look at used standard in scribus's code and reproduce them. Sample : See Official:Coding_Standards for a very detailed list and lots of advices.
 * use tabs not spaces
 * correct { and } positionning
 * use spaces where needed

How to get them approved faster
Patches should be in plain text. is the best way of sending them. Please do not send patches to the main list. Remember to use -u (unified diff) as other types of diff are painful to use.

'svn diff --revision 18833 > mypatch.diff' creates the patch from the revision 18833 to the version of your working dir.

Clean the patch so as to delete useless changes as tabs vs spaces.

Please ensure that when you have changed something in the code you put a comment immediately before the change. Ensure you put a date and who made the change and what the change is for. Over time, these will be weeded out, but it useful to see what has been altered.

Applying the right diff flags
To apply a .diff file do. Option '-px' enables to skip x levels of the path of the files as specified in the patch, in case the patch includes some parasite path root levels.
