docker-emacsen

Build a Docker image with multiple versions of Emacs. Currently, versions 22.3, 23.4, 24.5, 25.3, and the latest development snapshot are supported. They are installed in separate directories under /usr/local.

The image is published in Docker Hub as larsbrinkhoff/emacsen. These are the binaries provided:

• /usr/local/emacs-22.3/bin/emacs
• /usr/local/emacs-23.4/bin/emacs
• /usr/local/emacs-24.5/bin/emacs
• /usr/local/emacs-25.3/bin/emacs
• /usr/local/emacs-snapshot/bin/emacs

Among other things, it can be used to test Emacs packages. For an example, see how forth-mode is tested in Wercker: https://github.com/larsbrinkhoff/forth-mode/blob/master/wercker.yml
