Guidance to set triggers

[carlitux]

If I have this

  ls.parser.parse_snippet(
    {
      trig = "te",
      name = "ternary",
      dscr = ""
    },
    "${1:cond} ? ${2:true} : ${3:false}"
  ),

  ls.parser.parse_snippet(
    {
      trig = "e",
      name = "module export",
      dscr = ""
    },
    "export ${1:member}"
  ),

and I have editing

te|

must expand to |cond ? true : false but was expanded as texport |member

where | is the cursor

By default Luasnip just matches all snippet-triggers to the cursor position and expands whichever snippet matches first, disregarding word boundaries.
It's possible to only have snippets expand when they match the entire word before the cursor (conditional expansion, take a look at this snippet, you'd of course have to write a different function that checks if the word before the cursor matches the trigger), but not yet when parsing snippets.
As this is pretty common, I think I'll add some way to have parsed snippets behave that way aswell

Maybe add a key at the first argument that accepts out-the-box functions or a custom one? into the parser function

Yeah, that's the most comfortable way I think.

Alright, you can now set 'wordTrig' to only have snippets expand if the entire word matches, example here.
