| 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 |
|---|
| 5 | # - Add a key binding: |
|---|
| 6 | # { "keys": ["ctrl+shift+c"], "command": "clang_format" }, |
|---|
| 7 | # |
|---|
| 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. |
|---|
| 11 | # |
|---|
| 12 | # It operates on the current, potentially unsaved buffer and does not create |
|---|
| 13 | # or save any files. To revert a formatting, just undo. |
