Using OS user name / git user name inside code snippets

I’d like to add the following code snippet and share it with the whole team:

{
  "Comment todo": {
    "prefix": "//",
    "body": [
        "// TODO (${MY_NAME}) [${CURRENT_YEAR}-${CURRENT_MONTH}-${CURRENT_DATE}]: $1"
    ]
  }
}

This should produce // TODO (Alexander Kachkaev) [2018-12-07]: ... on my computer and // TODO (John Smith) [2018-12-07]: ... on John Smith’s.

Looking at VSCode snippet docs and VSCode variable reference does not suggest that there is any variable like MY_NAME. Could it be added? The value can either be taken from the OS user name or from the git user name. Similarly, there could be a variable for the current user’s email address (possibly taken from the git config).

WDYT?

If environment variables could be inserted into snippets, there would at least be a work around. Feels like it shouldn’t be a difficult update?

i’d also like to use git user values (specifically author / email) to include those in my changelog snippet. if not possible/wanted with git, at least let use store those values in vscode settings and use those.

but in the long run, support for extension settings values would be neat anyways. like ${git:username} or ${myext:sourcedir}

everything else i need is already in place and that’s so awesome =)
