DESCRIPTION *UltiSnips-description*
|
|
|
|
UltiSnips aims to provide a snippets solution that users came to expect from
|
|
editors. A Snippet is a short piece of text which is either typed very often
|
|
or which contains a lot of redundant text. Such snippets are very often
|
|
encountered in structured text like Source Code but I also use them for email
|
|
signatures and to insert the current date or time into the text while typing.
|
|
|
|
UltiSnips is an implementation that is developed with in the philosophy of TDD
|
|
(Test driven development). This guarantees that features do not disappear and
|
|
bugs do not reappear after they have been fixed once.
|
|
|
|
Acknowledgments: *UltiSnips-acknowledgments*
|
|
|
|
UltiSnips is inspired by the snippets solution implemented in TextMate
|
|
(http://macromates.com/). The idea of implementing snippets for vim is not new
|
|
and I want to thank Michael Sander (Author of snipMate) for some
|
|
implementation details I stole from him and for the permission to use some of
|
|
his snippets.
|
|

=============================================================================
|
|
2. INSTALLATION AND UPDATING *UltiSnips-installnupdate*
|
|
|
|
|
|
2.1 Installation *UltiSnips-installation*
|
|
----------------
|
|
|
|
UltiSnips has only been tested on Mac OS X and Linux. Like TextMates Snippets
|
|
it also relies heavily on shell integration, therefore Windows users will have
|
|
only a part of the functionality.
|
|
|
|
To use UltiSnips, you need a python enabled Vim 7. You have python if
|
|
:echo has("python")
|
|
yields '1'.
|
|
|
|
If you have Python, you only need to install UltiSnips. The recommended way to
|
|
do so is by using bzr (http://bazaar-vcs.org/). It is in all major linux
|
|
distribution (either package bzr or bazaar) and can be easily installed under
|
|
Mac OS X: >
|
|
$ easy_install bzr
|
|
|
|
To get UltiSnips, check it out into a directory of your choice. Then add this
|
|
directory to your Vim runtime path: >
|
|
$ cd ~/.vim/
|
|
$ bzr get lp:ultisnips ultisnips_rep
|
|
$ vim ~/.vimrc
|
|
|
|
add the line: >
|
|
set runtimepath+=~/.vim/ultisnips_rep
|
|
|
|
Restart vim. UltiSnips should work now. To access the help, use >
|
|
:helptags ~/.vim/ultisnips_rep/doc
|
|
:help UltiSnips
|
|
|
|
2.2 Deinstallation *UltiSnips-deinstallation*
|
|
------------------
|
|
|
|
To Uninstall UltiSnips, remove the directory you installed it to and remove
|
|
the path from your vim runtimepath: >
|
|
$ rm -rf ~/.vim/ultisnips_rep
|
|
$ vim ~/.vimrc
|
|
|
|
remove the line: >
|
|
set runtimepath+=~/.vim/ultisnips_rep
|
|
|
|
2.3 Updating *UltiSnips-updating*
|
|
------------
|
|
|
|
To Update an installation, simply pull the latest revision: >
|
|
$ cd ~/.vim/ultisnips_rep
|
|
$ bzr pull
|
|
|
|
=============================================================================
|
|
3. SETTINGS *UltiSnips-settings*
|
|
|
|
3.1 Commands *UltiSnips-commands*
|
|
------------
|
|
|
|
*:UltiSnipsEdit*
|
|
UltiSnipsEdit opens or creates your private snippet definition file for the
|
|
current filetype. You can easily open them manually of course, this is just a
|
|
shortcut. There is also a variable called: >
|
|
g:UltiSnipsEditSplit
|
|
which can be set to "normal" (default), "horizontal" or "vertical" that
|
|
defines if a new window should be opened for the edit. There is also a
|
|
variable called: >
|
|
g:UltiSnipsSnippetsDir
|
|
that, when set to a directory like "~/.vim/mydir/UltiSnips", becomes the base
|
|
directory for the snippet file to open. For example, if it is set to
|
|
"~/.vim/mydir/UltiSnips" and the current 'filetype' is "cpp", then
|
|
:UltiSnipsEdit will open "~/.vim/mydir/UltiSnips/cpp.snippets".
|
|
|
|
3.2 Triggers *UltiSnips-triggers*
|
|
------------
|
|
|
|
You can freely define the keys used to expand a snippet and jump forward and
|
|
backwards in it. There is also a key to list all snippets available for the
|
|
current expand situation. The variables with the default values are: >
|
|
g:UltiSnipsExpandTrigger <tab>
|
|
g:UltiSnipsListSnippets <c-tab>
|
|
g:UltiSnipsJumpForwardTrigger <c-j>
|
|
g:UltiSnipsJumpBackwardTrigger <c-k>
|
|
|
|
It is possible to set the Expand and Forward trigger to the same value. You
|
|
can get a more TextMate like configuration by adding the next three lines to
|
|
your vimrc: >
|
|
let g:UltiSnipsExpandTrigger="<tab>"
|
|
let g:UltiSnipsJumpForwardTrigger="<tab>"
|
|
let g:UltiSnipsJumpBackwardTrigger="<s-tab>"
|
|
|
|
3.3 Snippet Search Path *UltiSnips-snippet-search-path*
|
|
-----------------------
|
|
|
|
UltiSnips lets you override the name of the directories that are searched
|
|
for snippets. You need to set the variable g:UltiSnipsSnippetDirectories,
|
|
which defaults to: >
|
|
g:UltiSnipsSnippetDirectories ["UltiSnips"]
|
|
|
|
Snippet definition files are searched in 'runtimepath', but the 'runtimepath'
|
|
variable is traversed in reversed order (last item first). In each directory,
|
|
UltiSnips will search for the folder names in the order they appear in
|
|
g:UltiSnipsSnippetDirectories. If you keep your snippets in a folder called
|
|
"mycoolsnippets" in your .vim directory and you want the snippets that ship
|
|
with UltiSnips to be available as well, use >
|
|
let g:UltiSnipsSnippetDirectories=["UltiSnips", "mycoolsnippets"]
|
|
If you do not want the shipped snippets to be available, only use
|
|
"mycoolsnippets".
|
|
|
|
By default, UltiSnips will check for updates to .snippets files whenever
|
|
it is activated. This behavior can be disabled as follows: >
|
|
let g:UltiSnipsDoHash=0
|
|
|
|
See |UltiSnips-adding-snippet| for an introduction which files are parsed for
|
|
which file type.
|
|
|
|
3.4 Warning About Select Mode Mappings *UltiSnips-warning-smappings*
|
|
--------------------------------------
|
|
|
|
The help for vim's *mapmode-s* states: >
|
|
NOTE: Mapping a printable character in Select mode may confuse the user.
|
|
It's better to explicitly use :xmap and :smap for printable characters. Or
|
|
use :sunmap after defining the mapping.
|
|
|
|
But most vim plugins (even the ones shipped with vim) do not adhere to this.
|
|
As UltiSnips uses select mode to mark tabstops in snippets for overwriting
|
|
these wrong mappings get in the way. UltiSnips therefore defaults to
|
|
*:sunmap* all mappings for printable characters in select mode. It will not
|
|
touch any other mappings, especially not normal, insert or visual mode
|
|
mappings.
|
|
|
|
If this behaviour is not desired, you can disable it via >
|
|
let g:UltiSnipsRemoveSelectModeMappings = 0
|
|
|
|
If you want to keep certain mappings, you can modify the list of ignores for
|
|
this feature. For example >
|
|
let g:UltiSnipsMappingsToIgnore = [ "somePlugin", "otherPlugin" ]
|
|
|
|
will not unmap any mapping that contains the string "somePlugin" or
|
|
"otherPlugin" in its complete definition as listed by *:smap* .
|
|
|
|
|
|
3.5 Functions *UltiSnips-functions*
|
|
-------------
|
|
|
|
UltiSnips provides two functions for extending core functionality.
|
|
|
|
3.5.1 UltiSnips_AddSnippet *UltiSnips_AddSnippet*
|
|
|
|
The first function is UltiSnips_AddSnippet(trigger, value, description,
|
|
options, ...) which adds a new snippet to the current list of snippets with
|
|
the provided trigger, value, description, and options, see |UltiSnips-syntax|
|
|
for details on the meaning of those. All of the arguments are strings. You can
|
|
also specify the filetype for the new snippet with the final optional
|
|
argument.
|
|
|
|
3.5.2 UltiSnips_Anon *UltiSnips_Anon*
|
|
|
|
The second function is UltiSnips_Anon(value, ...), which expands an anonymous
|
|
Snippet. The snippet that gets expanded doesn't get added to the global list
|
|
of snippets, so it can't be expanded a second time unless the function is
|
|
called again. The value argument is the same as |UltiSnips_AddSnippet|. There
|
|
are also optional arguments, which are 1) the trigger, 2) the description of
|
|
the snippet, and 3) the options. All of the optional arguments are the same as
|
|
the |UltiSnips_AddSnippet| function. The description is unused right now,
|
|
whereas the trigger and options can change the way the snippet expands.
|
|
|
|
This feature is frequently used in .vimrc. A typical use case from my
|
|
restructured text file looks like this:
|
|
|
|
inoremap <silent> $$ $$<C-R>=UltiSnips_Anon(':latex:\`$1\`', '$$')<cr>
|
|
|
|
This expands the snippet whenever I type two $ signs. Note that In the right
|
|
hand site of the mapping, I retype the '$$' trigger and also inform UltiSnips
|
|
about the trigger; if I do not do this or give an empty trigger, vim will
|
|
trick UltiSnips by unreliably claiming that there is already one or zero '$'
|
|
signs before the snippet is expanded.
|
|
|
|
=============================================================================
|
|
4. SYNTAX *UltiSnips-syntax*
|
|
|
|
This chapter describes where to add new snippets and how to write them. I'll
|
|
provide many examples to make things clearer.
|
|
|
|
4.1 Adding Snippets *UltiSnips-adding-snippets*
|
|
-------------------
|
|
|
|
See |UltiSnips-snippet-search-path| for an explanation of where directories
|
|
with snippet definitions are expected.
|
|
|
|
While iterating over the snippet definition directories found, files are
|
|
looked for called ft.snippets or *_ft.snippets where "ft" is the current
|
|
'filetype', and the "*" matches anything, for example: >
|
|
ruby.snippets
|
|
c.snippets
|
|
my_c.snippets
|
|
perl.snippets
|
|
These files contain the snippet definitions for the various file types. A
|
|
special file is >
|
|
all.snippets
|
|
which contains snippets that are always expanded, no matter what file type is
|
|
defined. For example, I keep mail signatures and date insertion snippets here.
|
|
|
|
The dotted file type syntax of vim is supported. For example, for my cpp or
|
|
CUDA files, I keep the file type set to ":set ft=cpp.c" or ":set
|
|
ft=cuda.cpp.c". This activates all snippets for each file type in the order
|
|
specified.
|
|
|
|
As an alternative, a snippet file may contain a line that looks like this: >
|
|
extends ft1, ft2, ft3
|
|
For example, the first line in cpp.snippets looks like this: >
|
|
extends c
|
|
This means, first check all triggers for c, then add the triggers from this
|
|
file. This is a convenient way to add more special cases to more general ones.
|
|
Multiple "extends" lines are permitted throughout the snippets file.
|
|
|
|
The snippets file format is simple. A line starting with # is a comment, each
|
|
snippet starts with a line in the form of: >
|
|
snippet tab_trigger [ "description" [ options ] ]
|
|
The following lines are the snippets definition; a line starting with >
|
|
endsnippet
|
|
marks the end of the snippet. The trailing newline is chopped from the
|
|
definition. In the starting line, the description and options are optional.
|
|
|
|
If you want to use a multi-word trigger, you can surround the trigger with any
|
|
single character on each side. e.g. >
|
|
snippet "tab trigger" [ "description" [ options ] ]
|
|
or >
|
|
snippet !"tab trigger"! [ "description" [ options ] ]
|
|
if you actually want to include the double-quote characters in the trigger.
|
|
|
|
The description is only needed when more than one snippet is defined with the
|
|
same tab trigger. The user is then given a choice and the description is
|
|
displayed for the user as helper.
|
|
|
|
The options is a word of characters, each turning a specific option for this
|
|
snippet on. The options currently supported are >
|
|
! Overwrite - This snippet will overwrite all previously defined
|
|
snippets with this tab trigger. Default is to let the user choose at
|
|
expansion which snippet to expand. This option is useful to overwrite
|
|
bundled tab stops with user defined ones.
|
|
b Beginning of line - This snippet will only be expanded if you are at
|
|
the beginning of a line (that is if there are only whitespaces in front
|
|
of the cursor). Default is to expand snippets at every position, even
|
|
in the middle of a line. Most of my snippets have this option set, it
|
|
keeps UltiSnips out of the way.
|
|
i Inword expansion - Normally, triggers need whitespace before them to be
|
|
expanded. With this option, triggers are also expanded in the middle of
|
|
a word.
|
|
w Word boundary - Normally, triggers need whitespace before them to be
|
|
expanded. With this option, the trigger will be expanded at a "word"
|
|
boundary as well, where word characters are letters, digits, and the
|
|
underscore character ('_'). This enables expansion of a trigger that
|
|
adjoins punctuation (for example) without expanding suffixes of larger
|
|
words.
|
|
r Regular expression - This uses a python regular expression for the
|
|
match. The regular expression MUST be surrounded like a multi-word
|
|
trigger (see above) even if it doesn't have any spaces. The resulting
|
|
match is also passed to any python code blocks in your snippet
|
|
definition as the local variable "match".
|
|
t Don't expand tabs - By default, UltiSnips tries to expand leading tabs
|
|
in a snippet to match the results of automatic indentation. If this
|
|
option is set, UltiSnips will not try to do this expansion, and will
|
|
leave the tabs alone. This can be useful for snippets dealing with
|
|
tab delimited formats, etc.
|
|
f Do not turn 'formatoptions' off when expanding the snippet. Normally,
|
|
UltiSnips will disable the 'c' and the 't' option of 'formatoptions'
|
|
because otherwise, Vim might break a line without UltiSnips noticing
|
|
and this might mess up the snippet completely. This is useful for
|
|
snippets that need paragraphs in their tabstops.
|
|
<
|
|
|
|
4.1.1 Character Escaping: *UltiSnips-character-escaping*
|
|
|
|
In the snippet descriptions, various characters have special meaning
|
|
(e.g. '`{$\). If you want to insert any one of these characters literally,
|
|
prepend them with a single backslash (\).
|
|
|
|
4.2 Plaintext Snippets *UltiSnips-plaintext-snippets*
|
|
----------------------
|
|
|
|
Lets start with a simple example. Add this to your all snippets file: >
|
|
~/.vim/UltiSnips/all.snippets
|
|
|
|
------------------- SNIP -------------------
|
|
snippet bye "My mail signature"
|
|
Good bye, Sir. Hope to talk to you soon.
|
|
- Arthur, King of Britain
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
|
|
UltiSnips will pick up that you added/changed this file automatically, so just
|
|
try it in insert mode:
|
|
bye<tab> -->
|
|
Good bye, Sir. Hope to talk to you soon.
|
|
- Arthur, King of Britain
|
|
|
|
4.3 Interpolation *UltiSnips-interpolation*
|
|
-----------------
|
|
|
|
4.3.1 Shellcode: *UltiSnips-shellcode*
|
|
|
|
You can enter shellcode in your snippets in nearly all places. Shell code is
|
|
written to a script and then executed. The output is inserted into the snippet
|
|
instead of the shell code itself. Since the code is executed as a shell
|
|
script, you can use #!/bin/ notation to feed the input of your code to every
|
|
program you like. Let's consider an example that inserts the current date.
|
|
|
|
------------------- SNIP -------------------
|
|
snippet today
|
|
Today is the `date +%d.%m.%y`.
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
|
|
today<tab> ->
|
|
Today is the 15.07.09.
|
|
|
|
Another example doing the same using perl
|
|
------------------- SNIP -------------------
|
|
snippet today
|
|
Today is `#!/usr/bin/perl
|
|
@a = localtime(); print $a[3] . '.' . $a[4] . '.' . ($a[5]+1900);`.
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
today<tab> ->
|
|
Today is 15.6.2009.
|
|
|
|
4.3.2 VimScript: *UltiSnips-vimscript*
|
|
|
|
You can also use VimScript (also sometimes called VimL) in interpolation. This
|
|
works very much the same as interpolation of shellcode, expect that it must be
|
|
started by using `!v `. Let's consider a simple example, that counts the
|
|
indent of the current line:
|
|
|
|
------------------- SNIP -------------------
|
|
snippet indent
|
|
Indent is: `!v indent(".")`.
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
(note the 4 spaces in front): indent<tab> ->
|
|
(note the 4 spaces in front): Indent is: 4.
|
|
|
|
4.3.3 Python: *UltiSnips-python*
|
|
|
|
By far the most powerful interpolation is by using python code. The syntax is
|
|
similar to the one for Vimscript, but in python code the value of the property
|
|
"rv" on the "snip" object is inserted at the position of the code. Also, the
|
|
code is inside a `!p ` block. Python code gets some special variables defined
|
|
which can be used: >
|
|
|
|
fn - The current filename
|
|
path - The complete path to the current file
|
|
t - The values of the placeholders, t[1] -> current text of ${1} and so on
|
|
snip - Provides easy indentation handling.
|
|
|
|
The snip object provides the following methods: >
|
|
|
|
snip.mkline(line="", indent=None):
|
|
Returns a line ready to be appended to the result. If indent
|
|
is None, then mkline prepends spaces and/or tabs appropriate to the
|
|
current tabstop and expandtab variables.
|
|
|
|
snip.shift(amount=1):
|
|
Shifts the default indentation level used by mkline right by the
|
|
number of spaces defined by shiftwidth, 'amount' times.
|
|
|
|
snip.unshift(amount=1):
|
|
Shifts the default indentation level used by mkline left by the
|
|
number of spaces defined by shiftwidth, 'amount' times.
|
|
|
|
snip.reset_indent():
|
|
Resets the indentation level to its initial value.
|
|
|
|
snip.opt(var, default):
|
|
Checks if the vim variable "var" has been set, if so, it returns it,
|
|
otherwise it returns "default".
|
|
|
|
The snip object provides some properties as well: >
|
|
|
|
snip.rv:
|
|
the text that will fill this python block's position, it always starts
|
|
out as an empty string. This deprecates the "res" variable.
|
|
|
|
snip.c:
|
|
the text currently in the python block's position in the snippet
|
|
in it. You can check if snip.c is != "" to make sure that the
|
|
interpolation is only done once. This deprecates the "cur" variable.
|
|
|
|
snip.fn:
|
|
the current filename.
|
|
|
|
snip.basename:
|
|
the current filename without it's extension.
|
|
|
|
snip.ft:
|
|
the current filetype.
|
|
|
|
The snip object also provides some operators to make python snippets
|
|
easier: >
|
|
|
|
snip >> amount:
|
|
is equivalent to snip.shift(amount)
|
|
snip << amount:
|
|
is equivalent to snip.unshift(amount)
|
|
snip += line:
|
|
is equivalent to "snip.rv += '\n' + snip.mkline(line)"
|
|
|
|
Any variables set in a python block can be used in any following blocks.
|
|
Also, the vim, re, os, string and random modules are already imported inside
|
|
the snippet code. This allows for very flexible snippets. For example, the
|
|
following snippet mirrors the first Tab Stops value on the same line in
|
|
uppercase and right aligned:
|
|
|
|
------------------- SNIP -------------------
|
|
snippet wow
|
|
${1:Text}`!p snip.rv = (75-2*len(t[1]))*' '+t[1].upper()`
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
wow<tab>Hello World ->
|
|
Hello World HELLO WORLD
|
|
|
|
4.3.4 Global Snippets: *UltiSnips-globals*
|
|
|
|
Global snippets provide a way to take common code out of snippets. Currently,
|
|
only python code is supported. The result of executing the contents of the
|
|
snippet is put into the globals of each python block in the snippet file. To
|
|
create a global snippet, you use the keyword "global" in place of "snippet",
|
|
and for python code, you use "!p" for the trigger, for example, the following
|
|
is identical to the previous example, except that "upper_right" can be reused:
|
|
|
|
------------------- SNIP -------------------
|
|
global !p
|
|
def upper_right(inp):
|
|
return (75 - 2 * len(inp))*' ' + inp.upper()
|
|
endglobal
|
|
|
|
snippet wow
|
|
${1:Text}`!p snip.rv = upper_right(t[1])`
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
wow<tab>Hello World ->
|
|
Hello World HELLO WORLD
|
|
|
|
|
|
4.4 Tab Stops and Placeholders *UltiSnips-tabstops* *UltiSnips-placeholders*
|
|
------------------------------
|
|
|
|
Very often, it is convenient to quickly add some text snippet and jump on to
|
|
the next point of interest. This is were tabstops come in:
|
|
|
|
------------------- SNIP -------------------
|
|
snippet jump
|
|
I $1 I was a $2.
|
|
$0
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
jump<tab>wish<c-j>hunter<c-j>more text ->
|
|
I wish I was a hunter.
|
|
more text
|
|
|
|
You can use <c-j> and <c-k> to jump to the next tab or the previous. <Tab> was
|
|
not used for jumping forward because many people (like myself) use <tab> also
|
|
for completion. $0 is a special tab: This is the last tab in the snippet, no
|
|
matter how many tabs were defined before.
|
|
|
|
Most of the time it is more useful to have some default text for a tabstop and
|
|
sometimes it is also useful to have a tab stop in a tab stop. Consider the
|
|
next example which could be a real life scenario from a HTML snippet:
|
|
|
|
------------------- SNIP -------------------
|
|
snippet a
|
|
<a href="$1"${2: class="${3:link}"}>
|
|
$0
|
|
</a>
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
|
|
Here, $1 marks the first tabstop; it is assumed that you always want to add a
|
|
url as href. After entering it you jump to $2 which has the default text '
|
|
class="link"'. Now, you can either hit backspace, because you do not want to
|
|
enter a class attribute for this tag or you hit <c-j> to change the class name
|
|
(which is tab stop $3). When you are satisfied with the first line you hit
|
|
<c-j> again to finish this snippet and continue inside the anchor.
|
|
|
|
a<tab>http://www.google.com<c-j><BS><c-j>hi ->
|
|
<a href="http://www.google.com">
|
|
hi
|
|
</a>
|
|
|
|
a<tab>http://www.google.com<c-j><c-j>visited<c-j>hi ->
|
|
<a href="http://www.google.com" class="visited">
|
|
hi
|
|
</a>
|
|
|
|
Default tab stop text can also contain mirrors, transformations or
|
|
interpolation.
|
|
|
|
4.6 Mirrors *UltiSnips-mirrors*
|
|
-----------
|
|
|
|
Mirrors simply repeat the content of a tabstop. A classical example would be a
|
|
TeX Environment which needs a \begin{} and an \end{} tag:
|
|
|
|
------------------- SNIP -------------------
|
|
snippet env
|
|
\begin{${1:enumerate}}
|
|
$0
|
|
\end{$1}
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
env<tab>itemize ->
|
|
\begin{itemize}
|
|
|
|
\end{itemize}
|
|
|
|
Another typical example is #ifndef block in C code:
|
|
------------------- SNIP -------------------
|
|
snippet ifndef
|
|
#ifndef ${1:SOME_DEFINE}
|
|
#define $1
|
|
$0
|
|
#endif /* $1 */
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
ifndef<tab>WIN32 ->
|
|
#ifndef WIN32
|
|
#define WIN32
|
|
|
|
#endif /* WIN32 */
|
|
|
|
4.7 Transformations *UltiSnips-transformations*
|
|
-------------------
|
|
|
|
A complete description of the features follows, the chapter closes with some
|
|
demos, because this feature is rather mighty and hard to understand.
|
|
|
|
Transformations are like mirrors. But instead of just verbatim copying text
|
|
from the original tab stop, a regular expression is matched to the content of
|
|
the referenced tab stop and a transformation is then applied to the matched
|
|
pattern. UltiSnips follows the syntax and features of TextMate very closely
|
|
here.
|
|
|
|
A Transformation has the syntax >
|
|
${<tab stop no/regular expression/replacement/options}
|
|
|
|
with >
|
|
tab stop no - The number of the tab stop to reference
|
|
regular expression - The regular expression to match to the value of the
|
|
tab stop
|
|
replacement - The replacement string, see below
|
|
options - options for the regular expression
|
|
|
|
The options can be any combination of >
|
|
g - global replace, replaces all matches of the regular expression, not
|
|
just the first
|
|
|
|
Regular expressions are not handled here. Python regular expressions are used
|
|
internally, so the reference for matching is the re module of python:
|
|
http://docs.python.org/library/re.html
|
|
|
|
The replacement string is using a own syntax and is handled in the next paragraph.
|
|
|
|
4.7.1 Replacement String: *UltiSnips-replacement-string*
|
|
|
|
The replacement string can contain $no variables to reference matched groups
|
|
in the regular expression, $0 is special and yields the whole match. The
|
|
replacement string can also contain special escape sequences: >
|
|
\u - Uppercase next letter;
|
|
\l - Lowercase next letter
|
|
\U - Uppercase everything till the next \E
|
|
\L - Lowercase everything till the next \E
|
|
\E - End upper or lowercase started with \L or \U
|
|
\n - A newline
|
|
\t - A literal tab
|
|
|
|
Last, but not least the replacement string might contain conditional
|
|
replacements with the following syntax (?no:text:other text). This reads as
|
|
follows: if the group $no has matched, insert "text", otherwise insert "other
|
|
text". "other text" could be skipped and would default to "", that is the
|
|
empty string. This is a very powerful feature to add optional text into
|
|
snippets.
|
|
|
|
4.7.2 Demos: *UltiSnips-demos*
|
|
|
|
The transformations are very powerful but yield often a convoluted snippet
|
|
syntax. Therefore I offer for each feature a simple example below.
|
|
|
|
This shows uppercasing one character
|
|
------------------- SNIP -------------------
|
|
snippet title "Titelize in the Transformation"
|
|
${1:a text}
|
|
${1/\w+\s*/\u$0/}
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
title<tab>big small ->
|
|
big small
|
|
Big small
|
|
|
|
|
|
This shows uppercasing one character and global replace:
|
|
------------------- SNIP -------------------
|
|
snippet title "Titelize in the Transformation"
|
|
${1:a text}
|
|
${1/\w+\s*/\u$0/g}
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
title<tab>this is a title ->
|
|
this is a title
|
|
This Is A Title
|
|
|
|
This is a clever c-like printf snippet, the second tabstop is only shown
|
|
when there is a format (%) character in the first tab stop.
|
|
------------------- SNIP -------------------
|
|
snippet printf
|
|
printf("${1:%s}\n"${1/([^%]|%%)*(%.)?.*/(?2:, :\);)/}$2${1/([^%]|%%)*(%.)?.*/(?2:\);)/}
|
|
endsnippet
|
|
------------------- SNAP -------------------
|
|
printf<tab>Hello<c-j> // End of line ->
|
|
printf("Hello\n"); // End of line
|
|
|
|
But
|
|
printf<tab>A is: %s<c-j>A<c-j> // End of line ->
|
|
printf("A is: %s\n", A); // End of line
|
|
|
|
|
|
There are many more examples of what can be done with transformations in the
|
|
bundled snippets.
|
|
|
|
4.8 Clearing snippets *UltiSnips-clearing-snippets*
|
|
|
|
To remove snippets for the current file type, use the "clearsnippets"
|
|
directive:
|
|
------------------- SNIP -------------------
|
|
clearsnippets
|
|
------------------- SNAP -------------------
|
|
|
|
Without arguments, "clearsnippets" removes all snippets defined so far for the
|
|
current file type. UltiSnips travels in reverse along the 'runtimepath', so
|
|
"clearsnippets" removes snippet definitions appearing later in the
|
|
'runtimepath' than the ".snippets" file in which it's encountered.
|
|
|
|
Instead of clearing all snippets for the current file type, one or more
|
|
individual snippets may be cleared by specifying a space-separated list of
|
|
their triggers, e.g.:
|
|
|
|
------------------- SNIP -------------------
|
|
clearsnippets trigger1 trigger2
|
|
------------------- SNAP -------------------
|
|
|
|
This is useful if you only want to override a few triggers or all triggers
|
|
that came with UltiSnips with your own definitions. Note that you can
|
|
overwrite individual triggers when redefining them using the '!' option
|
|
(see |UltiSnips-adding-snippets| for the options).
