YASnippet is a template system for Emacs. It allows you to type an abbreviation and automatically expand it into function templates. Bundled language templates include: C, C++, C#, Perl, Python, Ruby, SQL, LaTeX, HTML, CSS and more. The snippet syntax is inspired from TextMate's syntax, you can even import most TextMate templates to YASnippet. Watch a demo on YouTube or download a higher resolution version.
Install the most recent version
Clone this repository somewhere
$ cd ~/.emacs.d/plugins $ git clone --recursive https://github.com/capitaomorte/yasnippet
Add the following in your
(add-to-list 'load-path "~/.emacs.d/plugins/yasnippet") (require 'yasnippet) (yas-global-mode 1)
Add your own snippets to
~/.emacs.d/snippets by placing files there or invoking
Install with el-get
El-get is a nice way to get the most recent version, too. See https://github.com/dimitri/el-get for instructions. Be sure to install the "master" branch since the 3.x series still use the old googlecode code, base. Consider using this "local" recipe.

yas-minor-mode on a per-buffer basis
To use YASnippet as a non-global minor mode, replace
(yas-global-mode 1) with
(yas-reload-all) to load the snippet tables. Then add a call to
(yas-minor-mode) to the major-modes where you to enable YASnippet.
(add-hook 'prog-mode-hook '(lambda () (yas-minor-mode)))
Where are the snippets?
Yasnippet no longer bundles snippets directly, but it's very easy to get some!
If you git-cloned yasnippet with the
--recursive option you'll also
download "git submodules" and find two subdirs under the main tree.
The default configuraiton already points to this dir, so to use them, just make sure the submodule really was downloaded (i.e. there are some files under
Points to a github repo of the yasmate tool, which is dedicated to converting textmate bundles into yasnippet snippets.
To use these snippets you have to run the tool first, so see its doc), and then point the
yas-snippet-dirsvariable to the
If you have a working ruby environment, you can probably get lucky directly with
Naturally, you can point
yas-snippet-dirs to good snippet collections out
there. If you have created snippets for a mode, or multiple modes,
consider creating a repository to host them, then tell users that it
should be added like this to
(setq yas-snippet-dirs '("~/.emacs.d/snippets" ;; personal snippets "/path/to/some/collection/" ;; foo-mode and bar-mode snippet collection "/path/to/yasnippet/yasmate/snippets" ;; the yasmate collection "/path/to/yasnippet/snippets" ;; the default collection )) (yas-global-mode 1) ;; or M-x yas-reload-all if you've started YASnippet already.
Manual, issues etc
Important note regarding bug reporting
Your bug reports are very valuable.
The most important thing when reporting bugs is making sure that we have a way to reproduce the problem exactly like it happened to you.
To do this, we need to rule out interference from external factors like other Emacs extensions or your own customisations.
Here's an example report that "sandboxes" an Emacs session just for reproducing a bug.
$ emacs --version Emacs 24.3 $ cd /tmp/ $ git clone https://github.com/capitaomorte/yasnippet.git yasnippet-bug $ cd yasnippet-bug $ git log -1 --oneline 6053db0 Closes #527: Unbreak case where yas-fallback-behaviour is a list $ HOME=$PWD emacs -L # This "sandboxes" your emacs, melpa configuration, etc (require 'yasnippet) (yas-global-mode 1) When I open a foo-mode file I can't expand foo-mode snippets! OR I can't get yasnippet to load because frankinbogen!
emacs -Q or temporarily moving your
.emacs init file to the side
is another way to achieve good reproducibility.
Here's a another example of a bug report. It has everything needed for a successful analysis and speedy resolution.
Also, don't forget to state the Emacs version (use
M-x emacs-version) and
the yasnippet version you are using (if using the latest from github,
git log -1 in the dir).
Any more info is welcome, but don't just paste a backtrace or an error message string you got, unless we ask for it.
There is also a YASnippet google group. I will keep the group open for reference and for discussion among users. Unfortunately I can't guarantee a timely response, so maybe it's better to create a github issue clearly marking your intent (user support/bug/feature request).
Finally, thank you very much for using YASnippet!
