add ability to run pre-load config #107

Closed cg505 closed 6 years ago

cg505 commented 6 years ago

At work I run emacs on WSL, using vcxsrv as my X server. This requires a line of emacs lisp in order to be able to even display the frame [1]. Putting this in my machine-local config meant that any time I broke the emacs config, my frame would not even display. This PR allows for adding arbitrary emacs lisp to a file ~/.emacs-emergency, which will be loaded if it exists before any of the rest of the config begins to load.

The name of ~/.emacs-emergency is somewhat arbitrary, but the location is not. In an effort to make sure this is always loaded, I wanted to keep the code as simplistic as possible. When loading the machine-local configuration, we have a function or two to figure out where the dot config is (though usually it is just ~/.config/dot/). I didn't want to do that, and hardcoding ~/.config/dot/emacs-emergency.el also seemed like a bad idea in case someone redefines $XDG_CONFIG_HOME.

Comments or suggestions welcome, this is a basic idea at this point and both design and implementation feedback are needed.

Also, a bit off topic, but this got me thinking about writing some sort of shell-script tests for things like running emacs with a different $XDG_CONFIG_HOME, running with/without .config/dot/emacs/init.el and ~/.emacs-emergency (or whatever), which can be executed by Travis.
