Class Method Details

.run(mode, *files) ⇒ Object

Open files by mode (:gui/:cui) mode. Launch emacs daemon if necessary. Create new frame if necessary. You can edit ~/.config/cmd_tools/config.yaml to specify an emacs executable. For example, if you are a Mac user who uses MacPorts, following modification will be useful.

- :emacs: emacs
+ :emacs: /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs
