Much like with Git, its easy to use TextMate as the editor that Mercurial will use for commit messages.

1. Open your ~/.hgrc file (create it if it doesn’t exist).
2. Add this entry to the [ui] section:

    [ui] editor = mate -w 

3. Save the ~/.hgrc file

Next time you do hg commit TextMate will open a temporary file you write your commit message into. Type your message, save the file and then close the window to finish the commit. The -w flag on the mate command tells TextMate not to return control to the command line until the editor window has been closed.
