How can I use several triggers for the same snippet?

Question

I have made a snippet which I want to give different triggers, so instead of say trigger I also want to trigger it with myothertrigger:

snippet trigger "just an example" 
my text ...
endsnippet

Is there an easy way to do this instead of copying the snippet?

Edit: To be clear, I am using UltiSnips, but if there is a better plugin I might look into that.

Answer 1

Currently there is no way to do this in UltiSnips. There is an open feature-request on Github for it though. Personally, I would like an alias functionality for triggers as indicated here too.

Let's hope SirVer (the maintainer of UltiSnips) will think so too and include it in the future :)

Answer 2

Although there is no specific syntax for aliases you can achieve the same effect by using post_jump:

# c.snippets
global !p
def expand(snip):
    if snip.tabstop != 1:
        return
    vim.eval('feedkeys("\<C-R>=UltiSnips#ExpandSnippet()\<CR>")')
endglobal

snippet incstdlib "#include <stdlib.h>" !b
#include <stdlib.h> /* exit(), malloc(), free() */
$0
endsnippet

post_jump "expand(snip)"
snippet incexit "#include <stdlib.h>" !b
incstdlib$1
endsnippet

In this snippets file the trigger incexit is an "alias" of trigger incstdlib. In reality incexit expands to incstdlib and the expand(snip) is called when UltiSnips moves to the tabstop $1. The expand(snip) just executes the VimScript function UltiSnips#ExpandSnippet which will expand incstdlib into it's final expanded form #include <stdlib.h>.

Another options is to use UltiSnips regular expression support instead:

snippet "inc(true|false|bool)" "#include <stdbool.h>" r
#include <stdbool.h> /* true, false */
endsnippet

Here you will have three triggers inctrue, incfalse and incbool that are effectively the same. The only drawback is that autocompletion plugins like YouCompleteMe will not autocomplete those.

Plugin neosnippet.vim support multiple trigger by keyword 'alias',
e.g. there have three triggers if myif myif2:

snippet     tcl::if
options     head
alias       if myif myif2
abbr tcl::if
    if { ${0:#:TARGET} } {
    }
