Creating these files were out of the desire to have more features and better capabilities for writing and editing mel scripts. There wasn't much of this for the Mac, so why not use Apple's own development environment that allows for this sort of configuration. The desire to share this was to hopefully fill this need for other Mac users.
Since Xcode version 3, Apple has changed the method they use for configuration files, so these configuration files will only work with version 3 and above. This was only tested with Xcode 3.2.1, so there could be issues with earlier versions.
This is the first version of the configuration files and there could be rules that are not included that may lead to inaccurate color coding, so if anything is missed please make a comment, and mention the version of Maya, and the version of Xcode. Also Xcode will not automatically open MEL script files. This can be changed by changing the default application for the MEL files, or merely open the file from within Xcode.
First and foremost, make sure the Apple Developer tools are installed. They can be downloaded from Apple's Developer site
(download is free, but requires a an ADC registration, which is also free)
Download the xcodemelfiles.zip from here. This includes 3 files: mel.xclangspec, mel.xcspec, mel.xcsynspec
Place these files into the following directory:
If this directory doesn't exist, just create it.
