python-editor is a library that provides the editor module for
programmatically interfacing with your system's $EDITOR. The user can
then enter a commit message for example.
.
Editor first looks for the ${EDITOR} environment variable. If set, it
uses the value as-is, without fallbacks. If no $EDITOR is set, editor
will search through a list of known editors, and use the first one that
exists on the system. For example, on Linux, editor will look for the
following editors in
order:
* vim
* emacs
* nano
