Is it possible to set a customizable variable when I start Emacs? E.g. I have a project name variable, which I usually set interactively using
M-x customize-variable, but I'd like to set it already when starting Emacs. I.e. so I can choose a project from the command line.
You can run
to do this. Or you could edit your settings file in such a way that it reads the customization from some environment variable, and set that on the command line.
