To configure emacs you can use the customize interface
M-x customize, but I’ll often provide bits of code to put into your emacs config file. This is a file containing pieces of emacs lisp (the language emacs is written in) that alter the behaviour of emacs.
Your emacs config file is probably in one of three places:
~/.emacsthough this is now a bit outdated and instead it will usually be in
- but, if you are using my recommended set up prelude then your emacs config file will be in
.elfile in that directory will be read when emacs starts.
Once you make a change to your emacs config file, you can highlight the section of code and run
M-x eval-region, or if it is a big change, you might need to restart emacs for it to take effect properly.
