Trigger snippet completion only in commented lines?

[rodhash]

For instance this custom snippet to ignore Typescript errors which we need to add in a commented line:

  "tsignore": {
    "prefix": "@ts",
    "body": [
      "@ts-ignore"
    ],
    "description": "Suppresses @ts-check errors on the next line",
    "scope": "typescript"
  },

This is triggering also when I'm typing an user email address when I hit @.

Any way to trigger this only on a line commented out?

UPDATE: increased keyword_length and now it's not triggering with just one char (which was annoying). But I'm wondering if forcing a snippet to trigger only in a particular situation (comment) is a thing. I saw a vid from TJ but it doesn't seem to be the case.

Oh yeah, it is a thing, check condition.
But you'll have to define your snippet in lua for this to work, it is not available for vscode-like snippet sources.

(the general blueprint is to find the current cursor position in condition, then check if the cursor is inside a comment by simple parsing or by querying treesitter)
