Quick start
|
|
||||||
===========
|
|
||||||
|
|
||||||
*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](#import-textmate)
|
|
||||||
|
|
||||||
YASnippet is an original creation of [pluskid][pluskid] who also wrote its predecessor
|
|
||||||
[smart-snippet][smart-snippet].

|
|
||||||
Installation
|
|
||||||
------------
|
|
||||||
|
|
||||||
Clone this repository somewhere
|
|
||||||
|
|
||||||
$ cd ~/.emacs.d/plugins
|
|
||||||
$ git clone https://github.com/capitaomorte/yasnippet
|
|
||||||
|
|
||||||
Add the following in your =.emacs= file:
|
|
||||||
|
|
||||||
(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`.
|
|
||||||
|
|
||||||
Import textmate snippets (rails example)
|
|
||||||
----------------------------------------
|
|
||||||
|
|
||||||
YASnippet lets you use TextMate bundles directly:
|
|
||||||
|
|
||||||
$ cd ~/.emacs.d/plugins
|
|
||||||
$ git clone https://github.com/capitaomorte/yasnippet
|
|
||||||
$ cd 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. Consider that this is a work-in-progress and many snippets/commands
|
|
||||||
might not work. Patches welcome!
|
|
||||||
|
|
||||||
Contributing snippets
|
|
||||||
---------------------
|
|
||||||
|
|
||||||
Please *do not ask me* to add snippets to the default collection under
|
|
||||||
`/snippets`. This collection is considered frozen. 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.
|
|
||||||
I'm focusing on developing it and the accompanying `yas-setup.el` files that
|
|
||||||
guide it with more difficult importations. The idea is to deprecate `/snippets=
|
|
||||||
and replace it with =extras/imported`.
|
|
||||||
|
|
||||||
Documentation, issues, etc
|
|
||||||
--------------------------
|
|
||||||
|
|
||||||
Please refer to the comprehensive [documentation](docs) for full
|
|
||||||
customization and support. If you think you've found a bug, please report it
|
|
||||||
on [the GitHub issue tracker](issues). (please **do not** submit new
|
|
||||||
issues to the old [googlecode tracker](googlecode-tracker))
|
|
||||||
|
|
||||||
If you run into problems using YASnippet, or have snippets to contribute,
|
|
||||||
post to the [yasnippet forum](forum). Thank you very much for using

|
||||||
Organizing snippets
|
|
||||||
===================
|
|
||||||
|
|
||||||
Basic structure
|
|
||||||
---------------
|
|
||||||
|
|
||||||
Snippet collections can be stored in plain text files. They are arranged by
|
|
||||||
sub-directories naming *snippet tables*. These mostly name Emacs major names.
|
|
||||||
|
|
||||||
.
|
|
||||||
|-- c-mode
|
|
||||||
| `-- printf
|
|
||||||
|-- java-mode
|
|
||||||
| `-- println
|
|
||||||
`-- text-mode
|
|
||||||
|-- email
|
|
||||||
`-- time
|
|
||||||
|
|
||||||
The collections are loaded into *snippet tables* which the triggering
|
|
||||||
mechanism (see [Expanding snippets](#expand-snippets)) looks up and
|
|
||||||
(hopefully) cause the right snippet to be expanded for you.
|
|
||||||
|
|
||||||
Setting up `yas-snippet-dirs`
|
|
||||||
-----------------------------
|
|
||||||
|
|
||||||
The emacs variable `yas-snippet-dirs` tells YASnippet
|
|
||||||
which collections to consider. It's used when you activate
|
|
||||||
`yas-global-mode` or call
|
|
||||||
`yas-reload-all` interactively.
|
|
||||||
|
|
||||||
The default considers:
|
|
||||||
|
|
||||||
- a personal collection that lives in `~/.emacs.d/snippets`
|
|
||||||
- the bundled collection, taken as a relative path to `yasnippet.el` localtion
|
|
||||||
|
|
||||||
When you come across other snippet collections, do the following to try them
|
|
||||||
out:
|
|
||||||
|
|
||||||
;; 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 snippets with same names
|
|
||||||
appearing in collections later in the list. `yas-new-snippet` always stores
|
|
||||||
snippets in the first collection.
|
|
||||||
|
|
||||||
The `.yas-parents` file
|
|
||||||
-----------------------
|
|
||||||
|
|
||||||
It's very useful to have certain modes share snippets between themselves. To do
|
|
||||||
this, choose a mode subdirectory and place a `.yas-parents` containing a
|
|
||||||
whitespace-separated list of other mode names. When you reload those modes
|
|
||||||
become parents of the original mode.
|
|
||||||
|
|
||||||
.
|
|
||||||
|-- c-mode
|
|
||||||
| |-- .yas-parents # contains "cc-mode text-mode"
|
|
||||||
| `-- printf
|
|
||||||
|-- cc-mode
|
|
||||||
| |-- for
|
|
||||||
| `-- while
|
|
||||||
|-- java-mode
|
|
||||||
| |-- .yas-parents # contains "cc-mode text-mode"
|
|
||||||
| `-- println
|
|
||||||
`-- text-mode
|
|
||||||
|-- email
|
|
||||||
`-- time
|
|
||||||
|
|
||||||
The `.yas-make-groups` file
|
|
||||||
---------------------------
|
|
||||||
|
|
||||||
If you place an empty plain text file `.yas-make-groups` inside one of the mode
|
|
||||||
directories, the names of these sub-directories are considered groups of
|
|
||||||
snippets and [the menu](snippet-menu) is organized much more cleanly:
|
|
||||||
|
|
||||||
(TODO image)
|
|
||||||
|
|
||||||
Another alternative way to achieve this is to place a `# group:` directive
|
|
||||||
inside the snippet definition. See [Writing Snippets](#writing-snippets)
|
|
||||||
|
|
||||||
|
|
||||||
$ tree ruby-mode/
|
|
||||||
ruby-mode/
|
|
||||||
|-- .yas-make-groups
|
|
||||||
|-- collections
|
|
||||||
| |-- each
|
|
||||||
| `-- ...
|
|
||||||
|-- control structure
|
|
||||||
| |-- forin
|
|
||||||
| `-- ...
|
|
||||||
|-- definitions
|
|
||||||
| `-- ...
|
|
||||||
`-- general
|
|
||||||
`-- ...
|
|
||||||
|
|
||||||
|
|
||||||
Yet another way to create a nice snippet menu is to write into
|
|
||||||
`.yas-make-groups` a menu definition. TODO
|
|
||||||
|
|
||||||
TODO The `.yas-setup.el` file
|
|
||||||
-----------------------------
|
|
||||||
|
|
||||||
*** TODO
|
|
||||||
|
|
||||||
TODO The `.yas-compiled-snippet.el` file
|
|
||||||
----------------------------------------
|
|
||||||
|
|
||||||
*** TODO
|
|
||||||
|
|
||||||
The `.yas-skip` file
|
|
||||||
--------------------
|
|
||||||
|
|
||||||
Expanding Snippets
|
|
||||||
==================
|
|
||||||
|
|
||||||
This section describes how YASnippet chooses snippets for expansion at point.
|
|
||||||
|
|
||||||
Maybe, you'll want some snippets to be expanded in a particular
|
|
||||||
mode, or only under certain conditions, or be prompted using
|
|
||||||
|
|
||||||
Triggering expansion
|
|
||||||
--------------------
|
|
||||||
|
|
||||||
To make a snippet expand after the cursor:
|
|
||||||
|
|
||||||
* Type an the snippet's *trigger key* then press the key defined in
|
|
||||||
`yas-trigger-key`.
|
|
||||||
|
|
||||||
* Use the snippet's *keybinding*.
|
|
||||||
|
|
||||||
* Call [`yas-insert-snippet=](#yas-insert-snippet) (use `M-x
|
|
||||||
yas-insert-snippet`= or its keybinding =C-c & C-s`).
|
|
||||||
|
|
||||||
* By expanding directly from the "YASnippet" menu in the menu-bar
|
|
||||||
|
|
||||||
* Using hippie-expand
|
|
||||||
|
|
||||||
* Use m2m's excellent [auto-complete](http://github.com/m2m/autocomplete)

|

|
** Setting up =yas-snippet-dirs=
|
||||||
|
|
||||||
|
The emacs variable [[#yas-snippet-dirs][=yas-snippet-dirs=]] tells YASnippet
|
||||||
|
which collections to consider. It's used when you activate
|
||||||
|
[[#yas-global-mode][=yas-global-mode=]] or call
|
||||||
|
[[#yas-reload-all][=yas-reload-all=]] interactively.

The default considers:

||||||
|
- a personal collection that lives in =~/.emacs.d/snippets=

It's very useful to have certain modes share snippets between themselves. To do
|
||||||
|
this, choose a mode subdirectory and place a =.yas-parents= containing a
|
||||||
|
whitespace-separated list of other mode names. When you reload those modes
|
||||||
|
become parents of the original mode.
|
||||||
|
|
||||||
|
#+begin_example
|
||||||
|
.
|
||||||
|
|-- c-mode
|
||||||
|
| |-- .yas-parents # contains "cc-mode text-mode"
|
||||||
|
| `-- printf
|
||||||
|
|-- cc-mode
|
||||||
|
| |-- for
|
||||||
|
| `-- while
|
||||||
|
|-- java-mode
|
||||||
|
| |-- .yas-parents # contains "cc-mode text-mode"
|
||||||
|
| `-- println
|
||||||
|
`-- text-mode
|
||||||
|
|-- email
|
||||||
|
`-- time

** TODO The =.yas-make-groups= file
|
||||||
|
|
||||||
|
If you place an empty plain text file =.yas-make-groups= inside one of the
|
||||||
|
mode directories, the names of these sub-directories are considered groups of
|
||||||
|
snippets and [[snippet-menu][the menu]] is organized much more cleanly:
|
||||||
|
|
||||||
|
(TODO image)
|
||||||
|
|
||||||
|
Another alternative way to achieve this is to place a =# group:= directive
|
||||||
|
inside the snippet definition. See [[#writing-snippets][Writing Snippets]]
|
||||||
|
|
||||||
|
#+begin_example
|
||||||
|
$ tree ruby-mode/
|
||||||
|
ruby-mode/
|
||||||
|
|-- .yas-make-groups
|
||||||
|
|-- collections
|
||||||
|
| |-- each
|
||||||
|
| `-- ...
|
||||||
|
|-- control structure
|
||||||
|
| |-- forin
|
||||||
|
| `-- ...
|
||||||
|
|-- definitions
|
||||||
|
| `-- ...
|
||||||
|
`-- general
|
||||||
|
`-- ...
|
||||||
|
#+end_example
|
||||||
|
|
||||||
|
Yet another way to create a nice snippet menu is to write into
|
||||||
|
=.yas-make-groups= a menu definition. TODO
|
||||||
|
|
||||||
|
** TODO The =.yas-setup.el= file
|
||||||
|
|
||||||
|
*** TODO
|
||||||
|
|
||||||
|
** TODO The =.yas-compiled-snippet.el= file
|
||||||
|
|
||||||
|
*** TODO
|
||||||
|
|
||||||
|
** The =.yas-skip= file
|
||||||
|
|

* Expanding Snippets

This section describes how YASnippet chooses snippets for expansion at point.
|
||||||
|
|
||||||
|
Maybe, you'll want some snippets to be expanded in a particular
|
||||||
|
mode, or only under certain conditions, or be prompted using
|
||||||
|
|
||||||
|
** Triggering expansion
|
||||||
|
|
||||||
|
To make a snippet expand after the cursor:
|
||||||
|
|
||||||
|
* Type an the snippet's *trigger key* then press the key defined in
|
||||||
|
[[#yas-trigger-key][=yas-trigger-key=]] (usually to "TAB").
|
||||||
|
|
||||||
|
* Use the snippet's *keybinding*.
|
||||||
|
|
||||||
|
* Call [[#yas-insert-snippet][=yas-insert-snippet=]] (use =M-x
|
||||||
|
yas-insert-snippet== or its keybinding =C-c & C-s=).
|
||||||
|
|
||||||
|
* By expanding directly from the "YASnippet" menu in the menu-bar
|
||||||
|
|
||||||
|
* Using hippie-expand
|
||||||
|
|
||||||
|
* Use m2m's excellent auto-complete
