For Vim version 7.0 or later.
|
||
|
This plugin only works if 'compatible' is not set.
|
||
|
{Vi does not have any of these features.}
|
||
|
|
||
|
SnipMate depends on vim-addon-mw-utils and tlib.
|
||
|
|
||
|
==============================================================================
|
||
|
DESCRIPTION *SnipMate-description*
|
||
|
|
||
|
SnipMate implements snippet features in Vim. A snippet is like a template,
|
||
|
reducing repetitive insertion of pieces of text. Snippets can contain
|
||
|
placeholders for modifying the text if necessary or interpolated code for
|
||
|
evaluation. For example, in C, typing "for" then pushing <Tab> could expand
|
||
|
to: >
|
||
|
|
||
|
for (i = 0; i < count; i++) {
|
||
|
/* code */
|
||
|
}
|
||
|
|
||
|
SnipMate is inspired by TextMate's snippet features.
|
||
|
|
||
|
==============================================================================
|
||
|
USAGE *SnipMate-usage*
|
||
|
|
||
|
Every snippet consists of an expansion and a trigger. Typing a trigger into
|
||
|
your buffer and then hitting your trigger key (<Tab> by default, see
|
||
|
|SnipMate-mappings|) will replace the trigger with the expansion text.
|
||
|
|
||
|
The expansion text can optionally include tab stops. When it does, upon
|
||
|
expansion of the snippet, the cursor is placed at the first one, and the user
|
||
|
can jump between each tab stop. Each of these tab stops can be represented by
|
||
|
default placeholder text. If such a placeholder is provided, then the text of
|
||
|
the placeholder can be repeated in the snippet at specified mirrors. Any edits
|
||
|
to the placeholder are instantly updated at every mirror.
|
||
|
|
||
|
SnipMate allows multiple snippets to use the same trigger. When triggered,
|
||
|
a list of all snippets with that trigger is provided and prompts for which
|
||
|
snippet to use.
|
||
|
|
||
|
*SnipMate-scopes*
|
||
|
SnipMate searches for snippets inside a directory named "snippets" inside each
|
||
|
entry in 'runtimepath'. Which files are loaded depends on 'filetype' and
|
||
|
'syntax'; see |SnipMate-syntax| for more information. Snippets are loaded and
|
||
|
refreshed automatically on demand.
|
||
|
|
||
|
Note: SnipMate does not ship with any snippets. In order to use it, the user
|
||
|
must either write their own snippets or obtain some from a repository like
|
||
|
https://github.com/honza/vim-snippets
|
||
|
|
||
|
==============================================================================

INTERFACE AND SETTINGS *SnipMate-interface* *SnipMate-settings*
|
||
|
|
||
|
*SnipMate-commands*
|
||
|
Commands~
|
||
|
|
||
|
*:SnipMateOpenSnippetFiles*
|
||
|
:SnipMateOpenSnippetFiles Opens a list of all valid snippet locations
|
||
|
based on the current scope |SnipMate-scopes|.
|
||
|
Only existing files and non-existing .snippets
|
||
|
files will be shown, with the existing files
|
||
|
shown first.
|
||
|
|
||
|
*SnipMate-options*
|
||
|
Options~
|
||
|
|
||
|
g:snips_author A variable used in some snippets in place of
|
||
|
the author's (your) name. Similar to
|
||
|
$TM_FULLNAME in TextMate. For example, >
|
||
|
snippet name
|
||
|
`g:snips_author`
|
||
|
< creates a snippet "name" that expands to your
|
||
|
name.
|
||
|
|
||
|
g:snipMate This |Dictionary| contains other SnipMate
|
||
|
options. In short add >
|
||
|
let g:snipMate = {}
|
||
|
< to your .vimrc before setting other SnipMate
|
||
|
options.
|
||
|
|
||
|
g:snipMate.scope_aliases A |Dictionary| associating certain filetypes
|
||
|
with other scopes |SnipMate-scopes|. The
|
||
|
entries consist of a filetype as the key and
|
||
|
a comma-separated list of aliases as the
|
||
|
value. For example, >
|
||
|
let g:snipMate.scope_aliases = {}
|
||
|
let g:snipMate.scope_aliases['ruby']
|
||
|
\ = 'ruby,ruby-rails'
|
||
|
< tells SnipMate that "ruby-rails" snippets in
|
||
|
addition to "ruby" snippets should be loaded
|
||
|
when editing files with 'filetype' set to
|
||
|
"ruby" or contains "ruby" as an entry in the
|
||
|
case of dotted filetypes.
|
||
|
|
||
|
g:snipMate['no_match_completion_feedkeys_chars']
|
||
|
A string inserted when no match for a trigger
|
||
|
is found. By default a tab is inserted
|
||
|
according to 'expandtab', 'tabstop', and
|
||
|
'softtabstop'. Set it to the empty string to
|
||
|
prevent anything from being inserted.
|
||
|
|
||
|
*SnipMate-mappings*
|
||
|
Mappings~
|
||
|
|
||
|
The mappings SnipMate uses can be customized with the |:map| commands. For
|
||
|
example, to change the key that triggers snippets and moves to the next
|
||
|
tabstop, >
|
||
|
|
||
|
:imap <C-J> <Plug>SnipMateNextOrTrigger
|
||
|
:smap <C-J> <Plug>SnipMateNextOrTrigger
|
||
|
|
||
|
The list of possible <Plug> mappings is as follows:
|
||
|
|
||
|
<Plug>SnipMateNextOrTrigger Default: <Tab> Mode: Insert, Select
|
||
|
Jumps to the next tab stop or, if none exists,
|
||
|
try to expand a snippet. Use in both insert
|
||
|
and select modes.
|
||
|
|
||
|
<Plug>SnipMateBack Default: <S-Tab> Mode: Insert, Select
|
||
|
Jump to the previous tab stop, if it exists.
|
||
|
Use in both insert and select modes.
|
||
|
|
||
|
<Plug>SnipMateShow Default: <C-R><Tab> Mode: Insert
|
||
|
Show all available snippets (that start with
|
||
|
the previous text, if it exists). Use in
|
||
|
insert mode.
|
||
|
|
||
|
<Plug>SnipMateVisual Default: <Tab> Mode: Visual
|
||
|
See |SnipMate-visual|.
|
||
|
|
||
|
Additionally, <CR> is mapped in visual mode in .snippets files for retabbing
|
||
|
snippets.
|
||
|
|
||
|
==============================================================================
|
||
|
SYNTAX *snippet-syntax* *SnipMate-syntax*
|
||
|
|
||
|
SnipMate looks inside of each entry of 'rtp' (or |SnipMate-snippet-sources|)
|
||
|
for a directory named /snippets/. Based on the 'filetype' and 'syntax'
|
||
|
settings (taking into account the dotted syntax), the following files are read
|
||
|
for snippets: >
|
||
|
|
||
|
.../snippets/<scope>.snippets
|
||
|
.../snippets/<scope>/<name>.snippets
|
||
|
.../snippets/<scope>/<trigger>.snippet
|
||
|
.../snippets/<scope>/<trigger>/<description>.snippet
|
||
|
|
||
|
where <scope> is an entry in 'filetype' or 'syntax', <name> is an arbitrary
|
||
|
name, <trigger> is the trigger for a snippet, and <description> is
|
||
|
a description used for |SnipMate-multisnip|.
|
||
|
|
||
|
A .snippet file defines a single snippet with the trigger (and description)
|
||
|
determined by the filename. The entire contents of the file are used as the
|
||
|
snippet expansion text.
|
||
|
|
||
|
Multiple snippets can be defined in *.snippets files. Each snippet definition
|
||
|
looks something like: >
|
||
|
|
||
|
snippet trigger optional description
|
||
|
guard left_from_cursor='^\s*'
|
||
|
expanded text
|
||
|
more expanded text
|
||
|
|
||
|
< *SnipMate-multisnip*
|
||
|
The description is optional. If it is left out and a second snippet inside the
|
||
|
same .snippets file uses the same trigger, the second one will overwrite the
|
||
|
first. Otherwise multisnip is used.
|
||
|
|
||
|
The guard condition line is also optional. It can be used to make a snippet
|
||
|
available only in some cases. The value should be a VimL expression.
|
||
|
|
||
|
Note: Hard tabs in the expansion text are required. When the snippet is
|
||
|
expanded in the text and 'expandtab' is set, each tab will be replaced with
|
||
|
spaces based on 'softtabstop' if nonzero or 'shiftwidth' otherwise.
|
||
|
|
||
|
Comments can be made in .snippets files by starting a line with a # character.
|
||
|
However these can't be used inside of snippet definitions: >
|
||
|
|
||
|
# this is a correct comment
|
||
|
snippet trigger
|
||
|
expanded text
|
||
|
snippet another_trigger
|
||
|
# this isn't a comment!
|
||
|
expanded text
|
||
|
|
||
|
This should hopefully be clear with the included syntax highlighting.
|
||
|
|
||
|
*snipMate-extends*
|
||
|
Borrowing from UltiSnips, .snippets files can also contain an extends
|
||
|
directive, for example: >
|
||
|
|
||
|
extends html, javascript, css
|
||
|
|
||
|
will tell SnipMate to also read html, javascript, and css snippets.
|
||
|
|
||
|
*SnipMate-tabstops*
|
||
|
Tab stops~
|
||
|
|
||
|
A tab stop, specified by ${#} where # is a number, tells SnipMate where to
|
||
|
position the cursor next. The special tab stop ${0} denotes the last cursor
|
||
|
position; in its absence, the cursor is placed at the end of the snippet.
|
||
|
|
||
|
For example, to place the cursor first on the id of a <div> tag, allow
|
||
|
the user to press <tab> to go to the middle of it, and finally end after
|
||
|
</div>: >
|
||
|
|
||
|
snippet div
|
||
|
<div id="${1}">
|
||
|
${2}
|
||
|
</div>
|
||
|
|
||
|
< *SnipMate-placeholders* *SnipMate-mirrors*
|
||
|
Placeholders and Mirrors~
|
||
|
|
||
|
Placeholder text can be supplied using "${#:text}", where # is the number of
|
||
|
the tab stop. This text then can be copied throughout the snippet using "$#",
|
||
|
given # is the same number as used before. So, to make a C for loop: >
|
||
|
|
||
|
snippet for
|
||
|
for (${2:i}; $2 < ${1:count}; $1++) {
|
||
|
${4}
|
||
|
}
|
||
|
|
||
|
This will cause "count" to first be selected and change if the user starts
|
||
|
typing. When <tab> is pressed, the "i" in ${2}'s position will be selected;
|
||
|
all $2 variables will default to "i" and automatically be updated if the user
|
||
|
starts typing.
|
||
|
|
||
|
NOTE: "$#" syntax is used only for mirrors, not for tab stops as in TextMate.
|
||
|
|
||
|
Mirrors can also be used inside of placeholders. For instance: >
|
||
|
|
||
|
snippet opt
|
||
|
<option value="${1:option}">${2:$1}</option>
|
||
|
|
||
|
Will, as usual, cause "option" to first be selected and update all the $1
|
||
|
variables if the user starts typing. Since one of these variables is inside of
|
||
|
${2}, this text will then be used as a placeholder for the next tab stop,
|
||
|
allowing the user to change it if he wishes.
|
||
|
|
||
|
To copy a value throughout a snippet without supplying default text, simply
|
||
|
use the "${#:}" construct without the text, e.g.: >
|
||
|
|
||
|
snippet foo
|
||
|
${1:}bar$1
|
||
|
|
||
|
< *SnipMate-visual*
|
||
|
There is a special placeholder called {VISUAL}. If you visually select text,
|
||
|
then press <Tab> Vim switches to insert mode. The next snippet you'll expand
|
||
|
will replace {VISUAL} by the text which was selected previously.
|
||
|
|
||
|
*SnipMate-eval*
|
||
|
Interpolated Vim Script~
|
||
|
|
||
|
Snippets can also contain Vim script commands that are executed (via |eval()|)
|
||
|
when the snippet is inserted. Commands are given inside backticks (`...`); for
|
||
|
TextMates's functionality, use the |system()| function. E.g.: >
|
||
|
|
||
|
snippet date
|
||
|
`system("date +%Y-%m-%d")`
|
||
|
|
||
|
will insert the current date, assuming you are on a Unix system. Note that you
|
||
|
can also (and should) use |strftime()| for this example.
|
||
|
|
||
|
Filename([{expr}] [, {defaultText}]) *SnipMate-Filename()*
|
||
|
|
||
|
Since the current filename is used often in snippets, a default function
|
||
|
has been defined for it in SnipMate.vim, appropriately called Filename().
|
||
|
|
||
|
With no arguments, the default filename without an extension is returned;
|
||
|
the first argument specifies what to place before or after the filename,
|
||
|
and the second argument supplies the default text to be used if the file
|
||
|
has not been named. "$1" in the first argument is replaced with the filename;
|
||
|
if you only want the filename to be returned, the first argument can be left
|
||
|
blank. Examples: >
|
||
|
|
||
|
snippet filename
|
||
|
`Filename()`
|
||
|
snippet filename_with_default
|
||
|
`Filename('', 'name')`
|
||
|
snippet filename_foo
|
||
|
`Filename('$1_foo')`
|
||
|
|
||
|
The first example returns the filename if it the file has been named, and an
|
||
|
empty string if it hasn't. The second returns the filename if it's been named,
|
||
|
and "name" if it hasn't. The third returns the filename followed by "_foo" if
|
||
|
it has been named, and an empty string if it hasn't.
|
||
|
|
||
|
==============================================================================
|
||
|
SNIPPET SOURCES *SnipMate-snippet-sources*
|
||
|
|
||
|
SnipMate is configurable.
|
||
|
|
||
|
plugin/SnipMate.vim assigns three important keys: >
|
||
|
|
||
|
" default implementation collecting snippets by handlers
|
||
|
let g:SnipMate['get_snippets'] = SnipMate#GetSnippets
|
||
|
" default handler:
|
||
|
let g:SnipMateSources['default'] = SnipMate#DefaultPool
|
||
|
" default directories containing snippets:
|
||
|
let g:SnipMate['snippet_dirs']
|
||
|
\ = funcref#Function('return split(&runtimepath,",")')
|
||
|
|
||
|
You can override all of those settings.
|
||
|
|
||
|
You can see that the default set of snippets is determined by Vim's 'rtp'.
|
||
|
|
||
|
Example 1:~
|
||
|
autoload/SnipMate_python_demo.vim shows how you can register additional
|
||
|
sources such as creating snippets on the fly representing python function
|
||
|
definitions found in the current file.
|
||
|
|
||
|
Example 2:~
|
||
|
Add to your ~/.vimrc: For each know snippet add a second version ending in _
|
||
|
adding folding markers >
|
||
|
|
||
|
let g:commentChar = {
|
||
|

|
||
|
\ 'cpp': '//',
|
||

|
||
|
==============================================================================
|
||
|
DISADVANTAGES *SnipMate-disadvantages*
|
||
|
|
||
|
SnipMate.vim currently has the following disadvantages to TextMate's snippets:
|
||
|
- Nested placeholders are not currently possible. E.g.: >
|
||
|
'<div${1: id="${2:some_id}}">${3}</div>'
|
||
|
< In TextMate this would first highlight ' id="some_id"', and if
|
||
|
you hit delete it would automatically skip ${2} and go to ${3}
|
||
|
on the next <tab>, but if you didn't delete it it would highlight
|
||
|
"some_id" first. You cannot do this in SnipMate.vim.
|
||
|
- Regex cannot be performed on variables, such as "${1/.*/\U&}"
|
||
|
- Placeholders cannot span multiple lines.
|
||
|
- Activating snippets in different scopes of the same file is
|
||
|
not possible.
|
||
|
|
||
|
Perhaps some of these features will be added in a later release.
