Source formatter (line breaks)

[The_Immortal]

Hi there!

Guys, I'm wondering is there an option that allows to put a line break for long code statements automatically?

Look at the picture please:



I never found any related to the problem option in Source formatter...


Could you help me please?



Thank you!

Probably you could write a script to do it on a menu/key command.

See here for details: http://wiki.codeblocks.org/index.php?title=Scripting_Code::Blocks

Actually I'm looking for some ready solutions...

Maybe you I have something regarding this?

Thank you!

Well, possibly.  The last version of astyle added this ability.  However, I do not believe the feature has yet made it into Code::Blocks' formatter plugin (or has it?).

Oh, guys... I just downloaded the latest version of AStyle (2.03) but have no idea how to involve it into CodeBlocks because there is no *.cbplugin file.

If you want to convert a single C file at a time; you might wish to try this link

It is a GUI that wrap the AStyle; it either that, wait till the CB team integrates it, or learn to use the command line version you downloaded.

Edit2: A second GUI cite http://universalindent.sourceforge.net/

Edit3: You could also patch CB to use the newer AStyle; but, that is beyond my ability, so, I did not think of it, at first.

Edit4: Looks like the CB AStyle version is "2.04 beta" found in file astyle_main.cpp. So, likely just the GUI code needs added to CB to use the feature. If you are good at wxWidgets you might be able to do it. I am still bad at wxWidgets and have no time to learn how to do it.

tested on win7 64bit
not many chages so it should work anywhere. (no boundary checking is performed for max line length value)

Please post the patch at the project's page on berlios.

i have made a short patch to add this feature:

Thanks for your patch. However, next time please consider to follow or coding guidelines, like format of brackets (i.e. in if-then clauses) and naming of methods: like "OnCheckBoxEvt" does not mean anything; use something as "OnPreview" instead which is easy to understand. This will make is easier for us to integrate proposed functionalities.
