There is a mapserver-mode for Emacs available at: https://github.com/AxxL/mapserver-emacs-mode This mode allows syntax-highlighting and code-indentation when a MapServer mapfile is opened in Emacs.
Please report issues directly via GitHub or via the mapserver-users list. There are still some issues around.
You can grab the necessary file at: https://github.com/AxxL/mapserver-emacs-mode/blob/master/mapserver-mode.el
Put it into: $HOME/.emacs.d/lisp/
You need to add the following lines to your $HOME/.emacs.d/init.el
(autoload ‹mapserver-mode «mapserver-mode» «Mode for editing UMN MapServer files.» t) (add-to-list ‹auto-mode-alist ‹(»\.map\›» . mapserver-mode))
If you haven’t specified your load-path it is a good idea to do it now. Put the following line before the other two lines.
(add-to-list ‹load-path «~/.emacs.d/lisp»)
Some help for Emacs is available at the Emacs Wiki
This file is a fork of Hal Muellers mapserver-mode which he announced nearly 10 years ago at the mapserver-users list. I simply updated the keywords and constants to the newest version and adjusted the regular expressions a bit.
In combination with yasnippet and auto-complete-mode you should have a nice way to edit mapfiles in your beloved Emacs environment.
