This is what I have in my emacs.d/init.el:
(global-set-key (kbd "C-x RET") 'compile)
So it's CTRL-C M and I get the compile prompt, which defaults to "make
-k", then enter. Of course I have a Makefile that contains ./rebar
compile in the default target.
Emacs knows how to go to the source line on error with CTRL `
I personally would not want my compiler to auto-compile when I saved
the file, though I realize some IDEs not only do that, but try to
compile as you type! Everyone has a different thing though.
