yasnippet and autopair/paredit conflict

Julien Cubizolles — 2013-03-06T22:58:19

I'm trying to define a snippet to insert \left( \right) structures in
LaTeX. I'd like it to be able to choose between parentheses, brackets,
square brackets with something like:

--8<---------------cut here---------------start------------->8---
\left$1$0\right$1
--8<---------------cut here---------------end--------------->8---

The thing is that I'm also using paredit and/or autopair modes in all
LaTeX buffers and if I type "(" during the snippet expansion, the
matching ")" is also inserted.

I've tried to temporarily disable paredit/autopair from within the
snippet template with no success so far. Any idea how I should go about
setting this up ?

Hello,
If you test the code below, you will notice that there is a small problem: 
" / yas / text " what appears, what I do not want.
How to correct the code?
Thank you.

# -*- mode: snippet -*-
# name:ensemble 
# key: ens
# --
${1:$$(yas/choose-value '("N" "Z" "D" "Q" 
"R"))}${1:$(yas/latex-choose-group yas/text)} $0

(defun yas/latex-choose-group (text)
  (cond ((string= text "N") "\$\\\mathbb{N}\$" )
        ((string= text "Z") "\$\\\mathbb{Z}\$" )
        ((string= text "D") "\$\\\mathbb{D}\$" )
        ((string= text "Q") "\$\\\mathbb{Q}\$" )   
        ((string= text "R") "\$\\\mathbb{R}\$" )))

http://code.google.com/p/yasnippet/issues/detail?id=197

When I write the following snippet, as I want to run some buffer clean-up
code after executing the snippet,


It didn't run the `do-some-cleanup' function.
It works when I execute (setq yas-after-exit-snipped-hook 'do-some-cleanup)

Is there any way to run arbitary elisp code in editing buffer
after I finished expansion?

Problem encountered when using auto-complete

F.YE — 2012-12-19T15:30:11

Transfer from yasnippet-bundle to yasnippet because the latter is easier to 
expand. But with yasnippet, one could not use "TAB" to complete the words 
provided by ac-dict (from auto-complete, also a fancy tool of which I fond 
a lot) while with yasnippet-bundle everything's OK. It's very embarrassing 
only to use "RET"(enter) to keep auto-complete working. Therefore, I wonder 
that out there might be somewhere a bug or something. The version of 
yasnippet I'm using is the lastest, I mean the very up-to-date. The version 
yasnippet-bundle is yasnippet-bundle-0.6.1c, which's also the lastest, it 
seems there's no more new bundle version. 

Thanks in advance for any possible help.

Problem with backslashes

Jim Burton — 2012-11-15T11:24:08


Hi, I have installed yasnippet 0.8 from elpa on emacs 24 and I want to 
write a snippet that inserts this text into a LaTeX document (using AUCTeX):

\\

\vspace{10pt}

So I have this snippet:

# -*- mode: snippet -*-
# name: para
# key: para
# binding: direct-keybinding
# expand-env: ((some-var some-value))
# type: command
# --
\\\\

\\vspace{10pt}

but when I type para<TAB> all that happens is that the text para is 
removed. What am I doing wrong?

Thanks!

Changelog for 0.7.0 and up?

shjk — 2012-07-25T14:20:07

Hi,

the changelog at http://capitaomorte.github.com/yasnippet/changelog.html stopped 
getting updated after the move to Github. I can't find any other place 
listing changes for 0.7.0 and 0.8.0, is this not documented anymore?

How to hide/overriding other snippet with same name defined for parent mode?

shjk — 2012-07-25T14:26:48

Hi,

I've got a hl snippet to produce a horizontal line up to the fill column 
which is defined for text-mode. For some modes that have text-mode as 
parent (via .yas-parent) I want to replace this with a different snippet. 
In 0.5.* this was possible by just adding a snippet with the same name in 
the more specific mode. In 0.7.0 I get asked which of the two snippets I 
want to expand (without making it possible to see which is which). Is it 
possible to tell yasnippet to always use the more specific one in 
0.7.0/0.8.0? I can create a work-around by having a more complex snippet 
that expands to different things depending on the major-mode but this is a 
bit inconvenient and a hacky non-solution.

Locating Python 2.x command for compiling doc

Dirk Ullrich — 2012-07-25T12:35:30

Hello,

I've noted that the Python script `doc/compile-doc.py' used for
generating HTML documentation works only with Python 2.x. Furthermore
it is called in the rake file by `sh doc/compile-doc.py ...'. Thus
locating of the Python command to use relies on the
`#!/usr/bin/python' line in the script.

Therefore the working of `doc/compile-doc.py' makes the asumption that
there is a Python 2 command at `/usr/bin/python'. This does not work,
for instance, for Arch Linux: On such a system `/usr/bin/python' is
Python 3; the Python 2 command would be at `/usr/bin/python2'. It
would also not work with Python 2 installation below `/usr/local'.

Thus I've implemented a in the rake file a search for a Python 2
command following the following heuristics: First we try to locate
`python2' whithin $PATH, and if this fails, we are looking for
`python' in $PATH. The diff appended patches `Rakefile' for doing
this.

Two caveats for my patch. I am not a Ruby programmer, so my
implementation my be a little bit clumsy. And and works only for
UNIX-like systems - but could easily enhanced for platform
independence (by enhancing the `which' function - see, for instance,
http://stackoverflow.com/questions/2108727/which-in-ruby-checking-if-program-exists-in-path-from-ruby).

Nested Snippets behaviour: Value of yas/text

OMF — 2012-07-22T17:09:32

I have written the following snippet for expanding the \sqrt function in 
latex. But There are problems when calling the snippet from within itself 
or any other snippets. ( I have yas/triggers-in-field set)

This function can be called as \sqrt{x} for a square root, or as 
\sqrt[n]{x} for an nth root. Calling it as \sqrt[]{x} causes problems, so 
the code below only prints the [] when n is a non-empty string

# -*- mode: snippet -*-
# key: rt
# group: math
# name : \sqrt[n]{x} or \sqrt{x}
# --
\sqrt${1:$(if (string-equal "" yas/text) "" "[")}${1:}${1:$(if 
(string-equal "" yas/text) "" "]")}{$2}$0

Now, this snippet works perfectly on its own, in latex-mode or using 
tryout-snippet. Typing
"rt TAB 3 TAB 2 TAB" produces \sqrt[3]{2}
and typing
"rt TAB TAB 2 TAB" produces \sqrt{2}
as expected

However, if it is called from within itself or another snippet, the snippet 
will not produce the square brackets. For example typing
"rt TAB 3 TAB rt TAB 5 TAB 2 TAB TAB"
produces
\sqrt[3]{\sqrt5{2}}

The yas/text field in the elisp code appears to have been detected as null 
in the nested snippet call.

Is there a workaround for this behaviour? Is there another yas/variable 
which contains the text that the elisp could should be calling? Any help 
would be appreciated.

How to insert conditionnal text

Paul Pichaureau — 2012-07-22T09:42:24

Hi,

I'm a new user of yasnippet, and I really enjoy it! It helps me *a lot* !

I use a lot of command on LaTeX with key syntax. I would like to make some 
part of snippet disappear if the I don't enter a string. For example

test<Tab>

will produce

\test[title={_}]

(the underscore is the cursor)

Now if I type <Tab>, the resulting text in the buffer should be

\test 

But if i type 'doo', I would like to see

\test[title={doo}]

Do you know if it's possible ?

Thank you very much !

Snippet for delimiters for LaTeX

Dror Atariah — 2012-07-19T08:35:22

In LaTeX you have several options for delimiters:

*\left< \right>*
*\left( \right)*
*\left\{ \right\}*
*...*
*
*
I want to write a snippet which will expand to these delimiters; I want it 
to be interactive, namely using "yas/choose-value". I encounter two 
problems:
1. Say that I chose the "<" delimiter, then at the end of the expression 
">" should appear. How can I do it?
2. The second problem relates to the usage of chars like "{" and "(". Is 
the following: *${2:$$(yas/choose-value '("<" "\{" "("))}* valid?

Thanks!

Moving one char backward when expanding the snippet

Dror Atariah — 2012-07-12T14:10:13

I'm trying to write a snippet which will expand to "\footnote{}" in LaTeX. 
The problem is the final code should look like:
*Hello World\footnote{The footnote}*
*
*
The goal is to be able to type the following:
*w o r d SPC f o o t TAB*
which will expand to:
*word\footnote{}*
I manage to get the following result:
*word \footnote{}*
*Note the space after 'word' which must not be there.*
*
*
I'm trying to use the *backward-char* function in the following way:
*`(backward-char 1)`\footnote{$1}$2*
but this doesn't work... I keep getting the space after the last word.

How can I avoid this? What is the right way to go?

snippets are not loading

Jakub Arnold — 2012-06-28T08:48:17

I'm having trouble with my custom snippets being loaded. My config for 
yasnippet is

(require 'yasnippet)
(setq yas/snippet-dirs
      '("~/.emacs.d/el-get/yasnippet/snippets"))
(yas/global-mode 1)

I've created a "new spec" snippet via (yas/new-snippet) which is in ~/.emacs.d/el-get/yasnippet/snippets/ruby-mode/new 
spec

It contains the following

# -*- mode: snippet -*-
# name: new spec
# key: spec
# --
require "spec_helper"

describe ${1:Class} do

  it "${2:spec description}" do
    $0
  end

end

If I invoke (yas/find-snippets) it puts me in 
~/.emacs.d/el-get/yasnippet/snippets where I can go to ruby-mode and open 
the new spec snippet and invoke C-c C-c it will load properly into the 
ruby-mode and work from that point on.

But it doesn't get loaded when I start emacs for the first time. I wasn't 
really able to find a guide that would explain yasnippet autoloading and 
creating new snippets.
