Taskjuggler (http://www.taskjuggler.org) is a project planning software which uses a plain text file for the definition of tasks which is then processed to create the schedule.

Unfortunately the built-in editor is Kate, which makes me scream. Any other editor than Emacs is hard to swallow for me.

Taskjuggler ships with a small emacs mode which does some highlighting and indention. From that I took the indention function and rewrote the rest from scratch.


I started this 2008-07-15 and finished it 2008-07-16 so it's probably pretty beta. But I will used it for quite some time. I only ever used it with TJ2x, not TJ3. Personally, I don't use TJ anymore so I can really tell.

Download and Install

Download taskjuggler-mode.el and call

  (require 'taskjuggler-mode)

from your init-file.

Since 2021 there's also a repo over at GitHub: https://github.com/ska2342/taskjuggler-mode.el

Emacs Version

This does NOT work in XEmacs. It shouldn't be too hard to port it, though. So, if you need this to support XEmacs, drop me a line.


C-c C-scheck syntax using taskjuggler backend
C-c C-ccompile using taskjuggler backend
C-c C-dInsert dependency with completion and (hopefully) correct relative path
C-c C-rInsert resource (with completion and context keywords)
C-c rRescan current buffer completely
C-c i tInsert task template
C-c i rInsert resource template


This mode highlights many words but without any knowledge of the context and the list is probably not complete.
