Reporting issues

Before reporting a bug, please take a look at:

To understand what’s going on, we need a reproducible bug scenario. It is important that we can rule out interference with other Emacs packages or customizations, therefore use emacs -Q to bypass your init file.

This shortcut will start emacs -Q for you with ivy-mode already loaded:

git clone https://github.com/abo-abo/swiper/
cd swiper
make plain

Contributing code

Here are the important settings for code style:

(setq indent-tabs-mode nil)
(require 'cl-indent)
(setq lisp-indent-function #'common-lisp-indent-function)
(put 'if 'common-lisp-indent-function 2)
(put 'defface 'common-lisp-indent-function 1)
(put 'defalias 'common-lisp-indent-function 1)
(put 'define-minor-mode 'common-lisp-indent-function 1)
(put 'define-derived-mode 'common-lisp-indent-function 3)
(put 'cl-flet 'common-lisp-indent-function
     (get 'flet 'common-lisp-indent-function))
(put 'cl-labels 'common-lisp-indent-function
     (get 'labels 'common-lisp-indent-function))

The setting for indent-tabs-mode is automatically applied by .dir-locals.el. Emacs produces a warning when setting lisp-indent-function in .dir-locals.el, so that line is commented out. Please uncomment it and add the following code to disable the warning:

(add-to-list 'safe-local-variable-values
             '(lisp-indent-function . common-lisp-indent-function))

Before submitting a change, run:

  • make compile - check for new compilation warnings
  • make test - check for failing tests
  • make checkdoc - check documentation guidelines

Use your own judgment for the commit messages, I recommend a verbose style using magit-commit-add-log.
