short and sweet LISP editing

Table of Contents


This package reimagines Paredit - a popular method to navigate and edit LISP code in Emacs.

The killer-feature are the short bindings:

   command                |   binding        |  binding     | command

——————————|——————|————–|——————- paredit-forward | C-M-f | j | lispy-down paredit-backward | C-M-b | k | lispy-up paredit-backward-up | C-M-u | h | lispy-left paredit-forward-up | C-M-n | l | lispy-right paredit-raise-sexp | M-r | r | lispy-raise paredit-convolute-sexp | M-? | C | lispy-convolute paredit-forward-slurp-sexp | C-) | > | lispy-slurp paredit-forward-barf-sexp | C-} | < | lispy-barf paredit-backward-slurp-sexp | C-( | > | lispy-slurp paredit-backward-barf-sexp | C-{ | < | lispy-barf

Most of more than 100 interactive commands that lispy provides are bound to a-z and A-Z in lispy-mode. You can see the full command reference with many examples here.

The price for these short bindings is that they are only active when:

The advantage of short bindings is that you are more likely to use them. As you use them more, you learn how to combine them, increasing your editing efficiency.

To further facilitate building complex commands from smaller commands, lispy-mode binds digit-argument to 0-9. For example, you can mark the third element of the list with 3m. You can then mark third through fifth element (three total) with 2> or >>. You can then move the selection to the last three elements of the list with 99j.

If you are currently using Paredit, note that lispy-mode and paredit-mode can actually coexist with very few conflicts, although there would be some redundancy.

Relation to vi

The key binding method is influenced by vi, although this isn't modal editing per se.

Here's a quote from Wikipedia on how vi works, in case you don't know:

vi is a modal editor: it operates in either insert mode (where typed text becomes part of the document) or normal mode (where keystrokes are interpreted as commands that control the edit session). For example, typing i while in normal mode switches the editor to insert mode, but typing i again at this point places an “i” character in the document. From insert mode, pressing ESC switches the editor back to normal mode.

Here's an illustration of Emacs, vi and lispy bindings for inserting a char and calling a command:

              | insert "j"     | forward-list

——————|—————-|————– Emacs | j | C-M-n vi in insert mode | j | impossible vi in normal mode | impossible | j lispy | j | j


Of course it's not magic, lispy needs to have normal/insert mode to perform both functions with j. The difference from vi is that the mode is explicit instead of implicit - it's determined by the point position or the region state:

So people who generally like Emacs bindings (like me) can have the cake and eat it too (no dedicated insert mode + shorter key bindings). While people who like vi can still get an experience that's reasonably close to vi for LISP editing (since vi's line-based approach isn't very appropriate for LISP anyway).

But if you ask:

What if I want to insert when the point is before/after paren or the region is active?

The answer is that because of the LISP syntax you don't want to write this:

   (forward-char 1))k

Also, Emacs does nothing special by default when the region is active and you press a normal key, so new commands can be called in that situation.


Some pictures here. - Code manipulation: - i prettifies code (remove extra space, hanging parens …) - xi transforms cond expression to equivalent if expressions - xc transforms if expressions to an equivalent cond expression - xf flattens function or macro call (extract body and substitute arguments) - xr evals and replaces - xl turns current defun into a lambda - xd turns current lambda into a defun - O formats the code into one line - M formats the code into multiple lines - Misc. bindings: - outlines navigation/folding (J, K, I, i) - narrow/widen (N, W) - ediff (b, B) - ert (T) - edebug (xe)

Getting Started

Installation instructions


It's easiest/recommended to install from MELPA. Here's a minimal MELPA configuration for your ~/.emacs:

(add-to-list 'package-archives '("melpa" . ""))

Afterwards, M-x package-install RET lispy RET (you might want to M-x package-refresh-contents RET beforehand if you haven't done so recently).

via el-get

el-get also features a lispy recipe. Use M-x el-get-install RET lispy RET to install.

Configuration instructions

Enable lispy automatically for certain modes

After installing, you can call M-x lispy-mode for any buffer with a LISP dialect source. To have lispy-mode activated automatically, use something like this:

(add-hook 'emacs-lisp-mode-hook (lambda () (lispy-mode 1)))

Enable lispy for eval-expression

Although I prefer to eval things in *scratch*, sometimes M-: - eval-expression is handy. Here's how to use lispy in the minibuffer during eval-expression:

(defun conditionally-enable-lispy ()
  (when (eq this-command 'eval-expression)
    (lispy-mode 1)
    (local-set-key "β" 'helm-lisp-completion-at-point)))
(add-hook 'minibuffer-setup-hook 'conditionally-enable-lispy)

Customization instructions

If you want to replace some of the lispy-mode's bindings you can do it like this:

(eval-after-load "lispy"
     ;; replace a global binding with own function
     (define-key lispy-mode-map (kbd "C-e") 'my-custom-eol)
     ;; replace a global binding with major-mode's default
     (define-key lispy-mode-map (kbd "C-j") nil)
     ;; replace a local binding
     (lispy-define-key lispy-mode-map "s" 'lispy-down)))

Operating on lists

How to get into list-editing mode (special)

The plain keys will call commands when: - the point is positioned before paren - the point is positioned after paren - the region is active

When one of the first two conditions is true, I say that the point is special. When the point is special, it's very clear to which sexp the list-manipulating command will be applied to, what the result be and where the point should end up afterwards. You can enhance this effect with show-paren-mode or similar.

Here's an illustration to this effect, with lispy-clone (here, | represents the point):

before | key | after ——————–|————–|———————— (looking-at "(")| | c | (looking-at "(") | | (looking-at "(")|

before | key | after ——————–|————–|———————— |(looking-at "(") | c | |(looking-at "(") | | (looking-at "(")

You can use plain Emacs navigation commands to get into special, or you can use some of the dedicated commands:

Key Binding | Description —————-|———————————————————– ] | lispy-forward - move to the end of the closest list, analogous to C-M-n (forward-list) [| lispy-backward - move to the start of the closest list, analogous to C-M-p (backward-list) C-3 | lispy-right - exit current list forwards, analogous to up-list ) | lispy-right-nostring exit current list forwards, but self-insert in strings and comments

These are the few lispy commands that don't care whether the point is special or not. Other such bindings are DEL, C-d, C-k.

Special is useful for manipulating/navigating lists. If you want to manipulate symbols, use region selection instead.

Digit keys in special

When special, the digit keys call digit-argument which is very useful since most lispy commands accept a numeric argument. For instance, 3c is equivalent to ccc (clone sexp 3 times), and 4j is equivalent to jjjj (move point 4 sexps down).

Some useful applications are 9l and 9h - they exit list forwards and backwards respectively at most 9 times which makes them effectively equivalent to end-of-defun and beginning-of-defun. Or you can move to the last sexp of the file with 999j.

How to get out of special

To get out of the special position, you can use any of the good-old navigational commands such as C-f or C-n. Additionally SPC will break out of special to get around the situation when you have the point between the open parens like this


and want to start inserting; SPC will change the code to this:

List commands overview

Inserting pairs

Here's a list of commands for inserting pairs:

key | command ——————|——————————————————————- ( | lispy-parens { | lispy-braces } | lispy-brackets " | lispy-quotes

Reversible commands

A lot of Lispy commands come in pairs - one reverses the other:

key | command | key | command —————-|————————–|———————————-|———————- j | lispy-down | k | lispy-up s | lispy-move-down | w | lispy-move-up > | lispy-slurp | < | lispy-barf c | lispy-clone | C-d or DEL | C | lispy-convolute | C | reverses itself d | lispy-different | d | reverses itself M-j | lispy-split | + | lispy-join O | lispy-oneline | M | lispy-multiline S | lispy-stringify | C-u " | lispy-quotes ; | lispy-comment | C-u ; | lispy-comment xi | lispy-to-ifs | xc | lispy-to-cond

Keys that modify whitespace

These commands handle whitespace in addition to inserting the expected thing.

key | command —————-|————————— SPC | lispy-space : | lispy-colon ^ | lispy-hat C-m | lispy-newline-and-indent

Command chaining

Most special commands will leave the point special after they're done. This allows to chain them as well as apply them continuously by holding the key. Some useful hold-able keys are jkf<>cws;. Not so useful, but fun is /: start it from |( position and hold until all your Lisp code is turned into Python :).

Navigating with ace-jump-mode-related commands

key | command —————-|————————– q | lispy-ace-paren Q | lispy-ace-char a | lispy-ace-symbol H | lispy-ace-symbol-replace - | lispy-ace-subword

q - lispy-ace-paren jumps to a “(” character within current top-level form (e.g. defun). It's much faster than typing in the ace-jump-mode binding + selecting “(”, and there's less candidates, since they're limited to the current top-level form.

a - lispy-ace-symbol will let you select which symbol to mark within current form. This can be followed up with e.g. eval, describe, follow, raise etc. Or you can simply m to deactivate the mark and edit from there.

- - lispy-ace-subword is a niche command for a neat combo. Start with:


Type c, -, b and C-d to get:


Fill end to finish the statement.

Operating on regions

Sometimes the expression that you want to operate on isn't bounded by parens. In that case you can mark it with a region and operate on that.

Ways to activate region

While in special: - Mark a sexp with m - lispy-mark-list - Mark a symbol within sexp a - lispy-ace-symbol.

While not in special: - C-SPC - set-mark-command - mark a symbol at point with M-m - lispy-mark-symbol - mark containing expression (list or string or comment) with C-M-, - lispy-mark

Move region around

The arrow keys j/k will move the region up/down within the current list. The actual code will not be changed.

Switch to the other side of the region

Use d - lispy-different to switch between different sides of the region. The side is important since the grow/shrink operations apply to current side of the region.

Grow/shrink region

Use a combination of: - > - lispy-slurp - extend by one sexp from the current side. Use digit argument to extend by several sexps. - < - lispy-barf - shrink by one sexp from the current side. Use digit argument to shrink by several sexps.

The other two arrow keys will mark the parent list of the current region:

To do the reverse of the previous operation, i.e. to mark the first child of marked list, use i - lispy-tab.

Commands that operate on region

IDE-like features

These features are specific to the Lisp dialect used. Currently Elisp and Clojure (via cider) are supported. There's also basic evaluation support for Scheme (via geiser) and Common lisp (via slime).


Bound to C-1. Show the doc for the current function inline.

C-h f is fine, but the extra buffer, and having to navigate to a symbol is tiresome. C-1 toggles on/off the inline doc for current function. No extra buffer necessary:


Here's how it looks for Clojure:



Bound to C-2. Show arguments for current function inline.

eldoc-mode is cool, but it shows you arguments over there and you're writing over here!. No problem, C-2 fixes that:


As you see, normal, &optional and &rest arguments have each a different face. Here's how it looks for Clojure:



Bound to g.

Use helm to select a symbol to jump to from all top-level symbols in the in current directory.

Works out of the box for Elisp, Scheme and Common Lisp. clojure-semantic is required for Clojure.
