Smartparens is a minor mode for dealing with pairs in Emacs.
It can automatically insert pairs:
wrap, unwrap and rewrap pairs:
expand and contract pairs:
and much more!
We generally target GNU Emacs version 24.3 and newer, however, everything should work mostly fine on anything newer than version 24.
You can now use smartparens with
M-x smartparens-mode. To
automatically enable smartparens in a programming mode:
;; Always start smartparens mode in js-mode. (add-hook 'js-mode-hook #'smartparens-mode)
You may want to try
smartparens-strict-mode. This enforces that
pairs are always balanced, so commands like
kill-line keep your code
M-x sp-cheat-sheet will show you all the commands
available, with examples.
We love pull requests. Please include tests. Smartparens uses ert-runner for testing. To run all the tests, run:
$ cask exec ert-runner
Alternatively, you can open the individual files in Emacs, then
You can learn more about how we test on the testing wiki page.
Smartparens has a default configuration that works well for most
languages. For language-specific behaviour, smartparens has a separate
smartparens-FOO.el file for every language and
smartparens-config.el loads these automatically.
If you want to support this project, you can:
Contribute code. If you have an idea that is not yet implemented and will benefit this project, feel free to implement it and submit a pull request. If you have any concerns whether your contribution will be accepted, ask beforehand. You can email the author or start an issue on the tracker.
Contribute ideas. Even if you can't code Emacs Lisp, you can still contribute valuable ideas for other programmers to implement. Simply start new issue on the tracker and submit your suggestion.
You can make a financial donation through PayPal or Patreon. If you like smartparens and can spare a modest amount on a donation, feel free to do so. These donations are expressions of your gratitude and are used for my personal "rewards" (books, games, music etc.). You can also gift me a game on Steam or buy something on Amazon. Regardless of the donations, smartparens will always be free both as in beer and as in speech.

Smartparens aims to provide a superset of these features, in all programming languages.
