Yet another snippet extension

Quick start
Organizing snippets

YASnippet is a template system for Emacs. It allows you to type an abbreviation and automatically expand it into function templates. Bundled language templates includes: 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 snippets

YASnippet is an original creation of /ld/yasnippet/src/commit/bdcecc0fe5af910f7e775e68e59e647ea4aaf72e/doc/pluskid who also wrote its predecessor /ld/yasnippet/src/commit/bdcecc0fe5af910f7e775e68e59e647ea4aaf72e/doc/smart-snippet.

Install the most recent version with git

Clone this repository somewhere

$ cd ~/.emacs.d/plugins $ git clone https://github.com/capitaomorte/yasnippet

Add the following in your .emacs file:

example (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 `yas/new-snippet`.

## Install yasnippet with el-get

El-get is a nice way to get the most recent version, too

Import textmate snippets (rails example)

Clone the yasnippet repository to `~/.emacs.d/plugins/yasnippet`

cd ~/.emacs.d/plugins/yasnippet git submodule init git submodule update gem install plist trollop rake convert_bundles # will convert ruby, rails and html bundles from drnic

Then, in your .emacs file

(add-to-list 'load-path "~/.emacs.d/plugins/yasnippet") (require 'yasnippet) (setq yas/snippet-dirs '("~/.emacs.d/snippets" "~/.emacs.d/extras/imported")) (yas/global-mode 1)

Open some rails file (model, app, etc) and start using the textmate snippets.

Contributing snippets

Please do not ask me to add snippets to the default collection under /snippets. This is considered frozen and by customizing yas/snippet-dirs you can point yasnippet to good snippet collections out there.

The extras/textmate-import.rb tool can import many actual Textmate snippets. See /ld/yasnippet/src/commit/bdcecc0fe5af910f7e775e68e59e647ea4aaf72e/doc/import-textmate.

I'm focusing on developping textmate-import.rb tool and the yas-setup.el files that guide it with more difficult importation. In the future /snippets snippets will be deprecated and replaced with extras/imported.

Documentation, issues, etc

Please refer to the comprehensive documentation for full customization and support. If you think you've found a bug, please report it on the GitHub issue tracker. (please do not submit new issues to the old googlecode tracker)

If you run into problems using YASnippet, or have snippets to contribute, post to the yasnippet forum. Thank you very much for using YASnippet!

Organizing snippets

Setting up `yas/snippet-dirs` before calling `yas/global-mode`

Snippet collections are stored in specially organized file hierarchies. These are loaded by YASnippet into snippet tables which the triggering mechanism (see Expanding snippets) looks up and (hopefully) cause the right snippet to be expanded for you.

An emacs variable yas/snippet-dirs tells YASnippet which collections to consider.

If you don't tweak it the default value of yas/snippet-dirs considers:

a personal collection that YASnippet decides lives in ~/.emacs.d/snippets
the bundled collection, taken as a relative path to yasnippet.el localtion

You might and probably want to try out more snippet collections though:

  ;; Develop in ~/emacs.d/mysnippets, but also
  ;; try out snippets in ~/Downloads/interesting-snippets
  (setq yas/snippet-dirs '("~/emacs.d/mysnippets"
                             "~/Downloads/interesting-snippets"))

  ;; OR, keeping yasnippet's defaults try out ~/Downloads/interesting-snippets
  (setq yas/snippet-dirs (append yas/snippet-dirs
                                 '("~/Downloads/interesting-snippets")))

Collections appearing earlier in the list shadow any conflicting snippets from collections later in the list. yas/new-snippet always stores snippets in the first collection.
