A template system for Emacs

Intro

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.

Installation

Manual install from Git

Clone this repository somewhere

$ cd ~/.emacs.d/plugins
$ git clone --recursive https://github.com/joaotavora/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.

Install with package-install

In a recent emacs M-x list-packages is the recommended way to list and install packages. It's available from GNU ELPA. If you need a very recent snapshot, you can get it from GNU-devel ELPA as well as MELPA (see http://melpa.org/#installing).

Install with el-get

El-get is another nice way to get the most recent version, too. See https://github.com/dimitri/el-get for instructions.

Use yas-minor-mode on a per-buffer basis

To use YASnippet as a non-global minor mode, don't call yas-global-mode; instead call yas-reload-all to load the snippet tables and then call yas-minor-mode from the hooks of major-modes where you want YASnippet enabled.

(yas-reload-all)
(add-hook 'prog-mode-hook #'yas-minor-mode)

Where are the snippets?

YASnippet no longer bundles snippets directly, but it's very easy to get some!

1. yasnippet-snippets - a snippet collection package maintained by AndreaCrotti.

   It can be installed with M-x package-install RET yasnippet-snippets if you have added MELPA to your package sources.

2. yasmate a 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-dirs variable to the .../yasmate/snippets subdir.

3. textmate-to-yas.el

   This is another textmate bundle converting tool using Elisp instead of Ruby.

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 yas-snippet-dirs:

(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
        ))

(yas-global-mode 1) ;; or M-x yas-reload-all if you've started YASnippet already.

Manual, issues etc

There's comprehensive documentation on using and customising YASnippet.

There's a list of support issues, with solutions to common problems and practical snippet examples.

The Github issue tracker is where most YASnippet-related discussion happens. Nevertheless, since YASnippet is a part of Emacs, you may alternatively report bugs to Emacs via M-x report-emacs-bug or sending an email to [email protected], putting "yasnippet" somewhere in the subject.

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/joaotavora/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 don't see foo-mode under the "YASnippet" menu!
OR
When loading yasnippet I see "Error: failed to frobnicate"!

Using 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, do 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.

Finally, thank you very much for using YASnippet!

yasnippet's Issues

Default Ruby snippets insert an extra empty line

The Ruby snippets all have a single line-feed (\n) character at the end of them. This is a bit annoying when you insert a snippet between two lines, cause you always endup with an extra empty line after the inserted snippet code.

Deal with multiple minor-mode conflict

Some other minor-mode is also defining key bindings: this might conflict
with yas/minor-mode (e.g. orgtbl ?). Try to deal with this problem.

I have added a another key support to snippet template file called as #key.
Some templates may will be named with characters unsupported by the
filesystem. The key if defined used as the template trigger.

For example: template named lt

No global snippets are available.

What steps will reproduce the problem?

1. I have following directory layout:
   .emacs.d
   +-> conf
   +-> snippets
   +-> c-mode
   | +-> php-mode
   +-> fundamental-mode
   | +-> css-mode
   +-> text-mode
   | +-> ...
   ...

2. It is possible to create snippets for the whole text-mode tree or the
   whole fundamental-mode tree, but not for all subtrees.

3. For example email would be a candidate for a global snippet. I want to
   insert my email address in .c files and in .el files. Now there is only the
   option to copy the files.

Another issue is the fact, that modes must be listed explicity before
snippets are applied. (I guess this is the same problem)
For example:

1. I have a snippet email in my directory .emacs.d/conf/snippets/c-mode and
   the folder .emacs.d/conf/snippets/c-mode/php-mode exists.
2. Then the snippet will work in php-mode.
3. If I delete or do not create the folder php-mode inside c-mode then the
   snippet will not work.

What is the expected output? What do you see instead?
It would be nice if snippets in .emacs.d/conf/snippets (in my scenario) are
globally available and modes do not need to be put explicitly in the tree
to inherit snippets.

What version of the product are you using? On what operating system?
Version 0.5.5 on Windows Vista

Please provide any additional information below.
I guess the key would be to look recursively what modes the currend mode
extends and look for snippets there.

[svn repo] indent-according-to-mode does not work properly due to narrowing

In yas/expand-snippet (narrow-to-region start start) hides indentation of
the line where a template is being expanded. This indentation is taken into
account by c-indent-line. For example:
template
if (${1:condition}) {
$0$&gt;
}$>
expands to:
if (condition) {
_
}

I suggest you to swap 'Step 13' and 'Step 14' in yas/expand-snippet and use
(overlay-end ...) as a limit for (re-search-forward ...):

    ;; Step 13: remove the trigger key
    (widen)
    (delete-char length)

    ;; Step 14: Do necessary indenting
    (save-excursion
      (let ((ovst (overlay-start (yas/snippet-overlay snippet)))
            (oven (overlay-end (yas/snippet-overlay snippet))))
        (when (and ovst oven)
          (goto-char ovst)
          (while (re-search-forward "$>" oven t)
            (replace-match "")
            (indent-according-to-mode)))))

What steps will reproduce the problem?

1. Install Emacs 22.1.1 under Linux
2. Install yasnippet
3. Open a new .cpp file and expand the `class' snippet.
4. Type the class name.

It should move the overlay when I type behind the field. But it didn't: the
insert-behind-hook is not being called after text is inserted.

set after-change-functions' to '() can fix this problem. but not proper way. Maybe I need to investigatec-after-change' and
jit-lock-after-change' (and event').

Provide after-exit-hook (and maybe similar hooks)

Sometimes you want to call a function before or after exit the snippet. For
example: call indent-region after exit the snippet. Maybe three level

Executing lisp code after TAB

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

I use MSF abbrevs since long for LATEX templates. I could replace it with
YASnippets (especially the compilation to one file etc.) if the elisp would
be (optionally) executed after going to the next field with TAB instead of
entering a single key.

e.g.:

# --
\section{${1:Name}}%
\index{${1:$(reftex-label)}}%

The reftex funktion takes a (depending on the files) long time to evaluate
the input $1, which makes the template useless to work with. msf abbrev
evaluates after finishing the field with tab, so the function is called once.

So my proposal would be to add some switch (or command) to have this behaviour.

Thank you

So, could you explain in what yasnippet differ from msfabbrev ?
Are you aware of anything like a comparative chart of all the
available modes ?

Why did you feel the need to rewrite smart-snippet ? How does it
work internally ? Why did you need to write your own templating
system (serious question since I find it is pretty closed to what
Msf Abbrev does).

Recursive snippet-editing

It would be really nice to have yasnippet work recursively. That is, when
editing a snippet 'tab' would, instead of just skipping to the next
snippet, first try to see if there is a new snippet in the current field,
and if so, insert that and start a 'stacked' snippet editing process.

I dont know if it's clear what I mean, but maybe this use case explains it
better:

There's two snippets:
'if' inserts a regular 'if' statement
'testx' insert 'test_for_x()'

ideally, when I want to insert the code
if (test_for_x()) {
// do something
}

I would type 'if', press tab (inserts the 'if' snippet'), type 'testx',
press tab (would insert the 'x' snippet!), and press tab again would jump
inside the curly braces of the if, exiting the snippet.

transform later in the snippet, obviously jumping to the first
non-transformed field instead would be preferable.

What version of the product are you using? On what operating system?

yasnippet 0.5.6 on Gnu Emacs 23.0.60

Please provide any additional information below.

Default code assigned to yas/buffer-local-condition does not work

(equal "font-lock-comment-face" (get-char-property (1- (point)) 'face))
is always nil because get-char-property returns a symbol not a string.
At least in GNU Emacs 23.

Certain snippets don't work properly with fci-mode enabled.

The and cls snippet and similar don't work properly with fci-mode enabled. The generated class name that's auto-inserted by the snippet gets inserted right at the end of the snippet, so you endup with:

class 

endMyAwesomeClass

Instead of:

class MyAwesomeClass

end

Aside from that, Yasnippet now works great for me with fci-mode :)

it can not work with python-mode.el on my machine.

hi,it is so cool!
but it it can not work with python-mode.el on my machine.
and the default python mode is not so well.

Snippet condition is evaluated twice

What steps will reproduce the problem?

1. Define snippet "test" in text-mode folder as below (also attached):

condition: (progn (message "hello!") (insert "foo") nil)

--

content

1. eval (yas/load-directory "~/lisp/snippets")
2. Get to text-mode buffer, type "test" and press TAB

What is the expected output? What do you see instead?

Expect to see "testfoo", with one "hello!" message in Messages. Actually
see "contentfoofoo" with two "hello!" messages in Messages. So in
addition to being evaluated twice, it's "succeeding" when it shouldn't
(because it returns nil).

Killing a snippet leaves garbage overlays behind

What steps will reproduce the problem?

1. insert a c 'for' snippet
   2.C-a C-k to "give up"
   3.start typing sthg else, green overlays appears

Just wondering if you already took care of this, the version I use is svn from a couple weeks
ago. I'll upload a patch that fixes it and goes well with your very nice coding style, tomorrow,
tonight I'm just trying out typing in iPhone hehehe.

Keep up the amazing work !

':' or '>' keys in c++-mode would break the snippet

Steps to reproduce,

1. type 'once' in c++ mode, and followed a tab
2. input 'test', and input '<' and '>'
   Then another 'test<>' is committed
3. type 'beginend' in c++ mode, and followed a tab
4. input 'a', and ':'
   Then the cursor moves to 'e'

snippet-local exit-hook

Quote from rubikitch's mail:

I want snippet-local yas/after-exit-snippet-hook.
Then I hacked up it using condition system.

(defvar yas/after-expand-sexp nil)
(defmacro yas/after-expand (&rest body)
 `(progn
    (setq yas/after-expand-sexp
          '(progn
             (save-restriction
               (narrow-to-region yas/snippet-beg yas/snippet-end)
               (goto-char yas/snippet-beg)
               ,@body
               (setq yas/snippet-end (point-max))
               (goto-char (point-max)))))
    t))
(setq yas/before-expand-snippet-hook nil)
(add-hook 'yas/after-exit-snippet-hook
         (lambda ()
           (eval yas/after-expand-sexp)
           (setq yas/after-expand-sexp nil)))

(defun yas/delete (regexp)
 (while (re-search-forward regexp nil t)
   (replace-match "")))

Rationale: I want to write snippets for Mocha, such as `mock' and `stub'.
Mock synopsis is "$1.expects(:$2).with($3).returns($4).times($5)".
`with', `returns' and `times' are optional.

mock = mock()
mock.expects(:method).returns(1)
mock = mock()
mock.expects(:method).with(1,2).returns(3)
mock = mock()
mock.expects(:method).with(1,2).returns(3).times(2)

So I wrote the snippet like this:

#name : mock
#condition: (yas/after-expand (yas/delete "\\.[a-zA-Z0-9]+(IGNORE)"))
# --
${1:mock} = mock()
$1.expects(:${2:method}).with(${3:IGNORE}).returns(${4:IGNORE}).times(${5:IGNORE})

For readability, a new snippet variable should be introduced, such as `after'.

Let different modes share some common snippets

One way is to support meta-information for modes:
{{{
import * from common-mode; // import all
import while from common-mode; // import only `while'
import while from common-mode as while2; // import and alias
}}}

Another way is to use complex directory hierarchy:
{{{
common-mode/
for
while
c-mode/
struct
c++-mode/
class
template
}}}

Suggestions

Hi!

I thought it would be better if we continued or discussion from
smart-snippet here.

I have tried it some more, and I really like it! I have found some things I
don't like though. Maybe you are working on them, but I will mention them
anyway.

1. Say I have the following snippet:

name : do if condition

--

if ${1:condition}

When I expand it I will at the end automaticly end up on a new line when
entered a condition. Sure I can do this:
if ${1:condition}$0

But it would have been more nice if you by default ended up after the last
character on the same row and instead do this:

name : do if condition

--

if ${1:condition}
$0

when you want to end up on the next row. I guess you more often want to en
up on the same line as the last char. At least I do. One example is shown
in point 3 where it actually can be seen as a bug.

2. Say I have more than one snippet with the same name. Then I get the nice
   menu. But it would have been even more nice if the first row in the menu
   was selected.

3. Say I have this:
   Model.find(:all)
   and now wants to add a condition (which I have a snippet for). Since the
   snippet behave like in point 1 I will get this:
   Model.find(:all, :conditions => ''
   )

with the right parenthesis on the next row.

4. I have discovered that lines with no text on wont get indented. This
   snippet will for example not indent line number 2 (the line with this on: $0).
   if ${1:condition}
   $0
   end

Other than the things mentioned above it's really nice!

Snippet files with diacritics not recognized properly

Hi!

What steps will reproduce the problem?

1. Create a snippet file with diacritics in its name. Eg.
   "snippets/text-mode/html-mode/hě".
   Contents of the file:

   $0

2. Start Emacs and open some HTML file.
3. Write "hě" and press TAB.

What is the expected output? What do you see instead?
Expected output is

. But it does nothing.

What version of the product are you using? On what operating system?
yasnippet 0.5.2, Emacs 22.1.1., Microsoft Windows XP Professional SP2 CZ.
Also not working with same yasnippet and emacs on Ubuntu Gutsy server.

Please provide any additional information below.

• snippets with diacritics in their name work if defined in elisp code.
  Eg.: (yas/define 'html-mode "hě" "

  $0

  " nil) works.
• Snippets with diacritics are useful for people, who write non-English
  documents. The example above: the letter 'ě' is in czech layout on the same
  position as '2' on english layout.

Error on expansion of snippets in html-mode

Hi!

As you might now Emacs has a cool feature in html-mode so that when you for
example do a "u-tag" Emacs will show an underline on the word in it. And if
you do a "h1-tag" Emacs will make it a bit larger and bold.

I have noticed that you cannot expand snippet when in one of those special
tags.
For example if I have:

My name %%{cursor here}

(%% is an expansion for <%= %>)

If I then try to expand I'll get this:
[yas]error in condition evaluation: Wrong type argument: stringp, (bold
underline)

"Bug", question and problem

Hi!

I have one problem, one question and "maybe" one bug. I don't know if it's
a bug or not but I don't like the behavior.

Bug)

# name : :conditions => {}
# --

:conditions => { :${1:attribute} => ${2:value} }

I want to use the name attribute, so I press TAB. But what if I have (I do)
a snippet for the ":" character. Then this would expand again to something
like this (in my case):
:conditions => { :symbol => attribute => value }

(":" is a snippet for ":symbol => ")

Maybe not a bug. But it would be nice to be able to turn off snippet
expansions when in a snippet expansion.

Problem)
The problem is about dropdown-menu.el
Maybe this is a bug to. I don't know. But when I use this, expand a snippet
and have several Emacs windows. All other windows than the one you are
working in disappears until I have chosen a snippet.

And also how do you chose a snippet you are on? I have only succeded that
by presses the number of it. The RETURN key would be the logic choise, but
nope...

Question)
A while ago I read somewhere about sharing snippets between modes. But I
cant find it now.

Thanks!
