Project

autocomplete-clang will look for a .clang_complete file as used by vim's clang_complete plugin, by searching up the directory tree. If it finds one, it'll use this to add parameters passed to clang. Use this for adding project-specific defines or include paths. The format is simply one parameter per line, e.g.

  -I/opt/qt/5.3/clang_64/lib/QtWebKitWidgets.framework/Versions/5/Headers
  -I/opt/qt/5.3/clang_64/lib/QtMultimedia.framework/Versions/5/Headers
  -DSWIFT_EXPERIMENTAL_FT

  'cmd-ctrl-alt-e': 'autocomplete-clang:emit-pch'

Misc

  • Motivation of the original author is C++, So that tests for C/Objective-C may be not enough.
