Install

Package manager

You can either install evil-lisp-state from MELPA:

 M-x package-install evil-lisp-state

Or add it to your Cask file:

(source melpa)

(depends-on "evil-lisp-state")

Manually

Add evil-lisp-state.el to your load path. evil-lisp-state requires both evil, bind-map and smartparens to be installed.

Principle

To execute a command while in normal state, a leader key is used. The leader has to be defined with the function evil-lisp-state-leader. By default any command when executed sets the current state to lisp state.

Examples:

• to slurp three times while in normal state:

  3 s

• to wrap a symbol in parenthesis then slurping two times:

  w 2 s

Configuration

No default binding comes with the package, you have to explicitly bind the lisp state to a key with the function evil-lisp-state-leader For instance:

(evil-lisp-state-leader ", l")

Key bindings are set only for emacs-lisp-mode by default. It is possible to add major modes with the variable `evil-lisp-state-major-modes'.

It is also possible to define the key bindings globally by setting evil-lisp-state-global to t. In this case `evil-lisp-state-major-modes' has no effect.

If you don't want commands to enter in lisp state by default set the variable evil-lisp-state-enter-lisp-state-on-command to nil. Then use the . to enter manually in lisp state
