1 # This file is a minimal clang-format sublime-integration. To install:
2 # - Change 'binary' if clang-format is not on the path (see below).
3 # - Put this file into your sublime Packages directory, e.g. on Linux:
4 # ~/.config/sublime-text-2/Packages/User/clang-format-sublime.py
6 # { "keys": ["ctrl+shift+c"], "command": "clang_format" },
8 # With this integration you can press the bound key and clang-format will
9 # format the current lines and selections for all cursor positions. The lines
10 # or regions are extended to the next bigger syntactic entities.
12 # It operates on the current, potentially unsaved buffer and does not create
13 # or save any files. To revert a formatting, just undo.
15 from __future__ import print_function
20 # Change this to the full path if clang-format is not on the path.
21 binary = 'clang-format'
23 # Change this to format according to other formatting styles. See the output of
24 # 'clang-format --help' for a list of supported styles. The default looks for
25 # a '.clang-format' or '_clang-format' file to indicate the style that should be
