Clang Format

What it does

Clang-format is a tool for formatting C++, built on LLVM. This is a package that allows you to run it easily from within Sublime Text.

About

In this package, we provide an alternative wrapper around clang-format for use within Sublime Text 3. Whilst LLVM does provide a very simple plugin to work with Sublime Text here, it doesn't really exploit any of the Sublime Text package functionality. We add new features such as customising the style from a settings file, selecting styles using the Command Palette, and easier installation.

Installing

• Install clang-format in one of the following ways:
  • Install using your package manager, e.g. sudo apt-get install clang-format or sudo apt-get install clang-format-5.0.
  • Download the entire LLVM toolchain and extract the clang-format binary. Just extract the .tar.xz file and copy bin/clang-format into your PATH (e.g. /usr/local/bin).
• Install this package through Package Control in the usual way.
• Set the path to the clang-format binaries. You can do this from within Sublime Text by choosing Clang Format - Set Path from the command palette. Hint: the path should look something like this [path/to/clang]/clang/bin/clang-format. If clang-format is in your system path, you shouldn't need to do anything.

Use

• Default shortcut is super+option+a on OSX and option+cmd+a otherwise. This will apply clang-format to the selection.
• From the command palette, you can select the formatting type by using Clang Format: Select Style. You will find the small number of defaults, and also a new 'Custom' entry. Selecting this entry allows you to customise the style through a settings file. You can access it from the main menu, under Package Settings. In this file you can add custom rules, such as Allmen style braces, and different indents. For examples see http://clang.llvm.org/docs/ClangFormatStyleOptions.html.
• Settings for the 'Custom' format and others are available through the Sublime Text preferences.
• It is possible to run the formatter on every save to a file, change settings to "format_on_save": true.
• To run the formatter in one stroke, press ctrl+e for windows and linux or super+e for OSX. You can always change the keybinding in the keymap to your liking.
• To change settings on a per-package basis, add them under ClangFormat key, example project.sublime-settings:

{
  "folders": [],
  "settings": {
    "ClangFormat": {
      "format_on_save": true
    }
  }
}
