A simple add-in to integrate AStyle into the IDE.
Install the add-in DLL, copy astyle.exe and astyle.cfg (both included) into Pelles C bin folder, tweak astyle.cfg (optional) and you'll have "AStyle" option in the editor context menu (in "Source" menu too).
I hope this is useful for someone besides myself. Maybe someone with more C/Windows API experience could clean the code and improve things here and there. If anyone does it, please post the improved add-in here.
BTW: Is there any way to assign a keyboard shortcut to an add-in?
