A plugin for Sublime Text for automatically unindenting the line when inserting a preprocessor directive in the [Objective]C/C++ code.
The plugin automatically unindents the line on pressing the '#' character if the cursor is preceded by a whitespace only.
The easiest and recommended way to install is through Package Control plugin. Once it's installed, restart Sublime Text and press CTRL+SHIFT+P on Windows/Linux or CMD+SHIFT+P on OS X to bring up the Command Pallete. From there look for Install Package and then for UnindentPreprocessor. Package Control will keep the plugin up to date automatically.
Otherwise it can be installed by cloning this repo while inside Sublime's Packages directory.
