Tips on how to edit lisp code efficiently.

Built-in modes

With evil-mode

Lispy, a vi-like paredit

Lispy makes it easier to edit lisp code when we use evil-mode.

It offers very short keybindings. For example, going to the next parenthesis is bound to j, s moves down the current expression, e to eval and xe to edebug, xd turns current lambda into a defun, etc

The price to pay is that the bindings are only active when:

  • the point is before an open paren: (, [ or {
  • the point is after a close paren: ), ] or }
  • the region is active



   M-x package-install RET lispy RET

(you might want to M-x package-refresh-content beforehand).

Tips and tricks

Make "dd" delete an expression

di( or da( isn't specific to lisp, they are just evil text objects.
