# 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.
