A TextMate bundle for the Lean language. This is also used by github/linguist to syntax-highlight Lean code in github.com.

After installing TextMate2, please execute the following instructions:

mkdir -p ~/Library/Application\ Support/Avian/Bundles
cd ~/Library/Application\ Support/Avian/Bundles
git clone https://github.com/leanprover/Lean.tmbundle.git

• Open TextMate

• Bundles >> Edit Bundles

  

• Lean >> Language Grammars

  

• Note: TextMate saves grammar files (.tmLanguage) in Apple's PLIST format, which makes it very difficult to edit them outside of TextMate. It rejects to save any mal-formed/incomplete files. While saving grammar files, TextMate also clean up any comments inside of them.
