#BBUncrustifyPlugin-Xcode

Xcode plugin to uncrustify code in Xcode.

Requirements

Tested with Xcode 4.6+ (also works in Xcode 5) on OS X 10.7 or higher.

PS: This fork works with Xcode 3.

Installation

• Build the Xcode project. The plug-in will automatically be installed in ~/Library/Application Support/Developer/Shared/Xcode/Plug-ins.

• Relaunch Xcode.

To uninstall, just remove the plugin from ~/Library/Application Support/Developer/Shared/Xcode/Plug-ins and restart Xcode.

How does it work?

• Use the menu Edit > Uncrustify Selected Files to uncrustify the selected items in the project navigator.

• Use the menu Edit > Uncrustify Active File to uncrustify the source file actually opened in the editor.

• Use the menu Edit > Uncrustify Selected Lines to uncrustify the selected source code (multiple selection is supported). The selection is automatically extended in full lines. If the selection is empty, it uses the line under the cursor.

PS: Modifications are recorded in the undo. So undo reverts the modifications.

You can create keyboard shortcuts for the menu items in the Keyboard Preferences of OS X System Preferences.

How to customize the uncrustify configuration?

By default, the plugin uses the configuration file uncrustify.cfg found in the bundle.

Per user configuration

To customize the configuration, copy the file uncrustify.cfg or your own to:

1. ~/.uncrustifyconfig or
2. ~/uncrustify.cfg or
3. ~/.uncrustify/uncrustify.cfg

Per project configuration

A configuration file named uncrustify.cfg or .uncrustifyconfig can be defined for a project, a workspace or a Xcode container folder (folder with the yellow icon in the Xcode files navigator).

The lookup of the configuration file is made in this order:

1. Closest Xcode container folder ancestor.
2. Closest Xcode project file ('.xcodeproj') folder ancestor.
3. Closest Xcode workspace file ('.xcworkspace') folder ancestor.

Example:

|-- workspace.xcworkspace
|-- uncrustify.cfg
|-- project folder
|---- project.xcodeproj
|---- Third Party Library Folder
|------ uncrustify.cfg
|-- An other project folder
|---- An other project.xcodeproj
|---- uncrustify.cfg

Using UncrustifyX

A more easy way to edit the configuration is to use the Mac appplication UncrustifyX.

Once UncrustifyX is installed, the plugin will add a menu item Open with UncrustifyX to open the actual source code and configuration in UncrustifyX.

Xcode Normalization

After uncrustification, the plugin:

• performs a syntax-aware indenting if checked in the Xcode preferences (Preferences > Text Editing > Indentation > Syntax-aware indenting).

• Trims trailing whitespaces and white-only lines if checked in the Xcode preferences (Preferences > Text Editing > Editing).

You can disable this feature by setting the default key uncrustify_plugin_codeFormattingSchemeto 1 (0 or not defined means enabled).

defaults write com.apple.dt.Xcode uncrustify_plugin_codeFormattingScheme -int 1
