I think maybe should post this topic to "Developer Chat", but I can't... :-( Recently I put my script on github. But github not show au3 file with syntax highlighting, just raw text no color - https://github.com/zackz/PuTTYAssist/blob/master/PuTTYAssist.au3 After some digging I found: * github use pygments for syntax highlighting, and github will support au3 if pygments support it, http://help.github.com/common-issues-and-questions/ * dozens of autoit project are already on github, they need syntax highlighting, https://github.com/search?langOverride=...it&repo=&start_value=1&type=Re * pygments 1.4 (released Jan 03, 2011) starts support Autohotkey, so ahk file in github has syntax highlighting, https://bitbucket.org/birkenfeld/pygments-main/src/81d98983fd7f/CHANGES Don't know whether autoit team are working on or considering about pygments. Hope github support au3 highlighting soon.. If there is a problem with github/pygments or python about highlighting, please let me know, maybe I can help
