ExtEdit is a Thunderbird/Icedove extension to allow editing an email in an external editor, such as Vim or Emacs. It is based on Alexandre Feblot’s External Editor extension.
This extension is in a very preliminary state, and has been updated just enough to get it working in modern versions of Thunderbird. Further work will aim to improve the codebase and add new features.
To build, simply type
make. You can then install the XPI in Thunderbird.
ExtEdit is licensed under your choice of the Mozilla Public License, version 1.1 or the GNU General Public License, version 2 or later.
Pull requests are welcome. The standard is to use hard tabs, aligned at four spaces. The current codebase is moving in that direction, even if it isn’t there yet.
