Subversion Repositories QNX 8.QNX8 LLVM/Clang compiler suite

# This file is a minimal clang-format sublime-integration. To install:

# - Change 'binary' if clang-format is not on the path (see below).

# - Put this file into your sublime Packages directory, e.g. on Linux:

#     ~/.config/sublime-text-2/Packages/User/clang-format-sublime.py

# - Add a key binding:

#     { "keys": ["ctrl+shift+c"], "command": "clang_format" },

#

# With this integration you can press the bound key and clang-format will

# format the current lines and selections for all cursor positions. The lines

# or regions are extended to the next bigger syntactic entities.

#

# It operates on the current, potentially unsaved buffer and does not create

# or save any files. To revert a formatting, just undo.

# a '.clang-format' or '_clang-format' file to indicate the style that should be

# used.
