Checklist:

• I am adding a new language.
  • The extension of the new language is used in hundreds of repositories on GitHub.com.
    • Search results for each extension:
      • https://github.com/search?q=(path%3A*.edge)+AND+(content%3A%40section+OR+content%3A%40if+OR+content%3A%40end+OR+content%3A%3Cdiv%3E)+NOT+is%3Afork&type=code
  • I have included a real-world usage sample for all extensions added in this PR:
    • Sample source(s):
      • https://github.com/adocasts/adocasts/blob/a8be4869db1355f77f2280744e50741b0e2aa694/resources/views/pages/pricing.edge
    • Sample license(s): https://github.com/adocasts/adocasts/blob/main/LICENSE
  • I have included a syntax highlighting grammar: https://github.com/edge-js/edge-vscode
  • I have added a color

    • Rationale: Color used in official Edge logo found on https://edgejs.dev
  • I have updated the heuristics to distinguish my language from others using the same extension.

One question I have is the grammar includes source.js#expression which is not available in the atom javascript textmate grammar, but is available in the microsoft grammar. I think GitHub uses the treesitter grammar for javascript, but I assume it will use the textmate grammar when being included by another textmate grammar. Can you confirm if my assumption is correct about using the textmate grammar when included by another textmate grammars, and if so which version of the grammar is in use.

@thetutlage If the atom grammar is being used I'd recommend updating the edge grammar to include source.ts#expression instead.

Correct a denoted by the 🐌 in the list of grammers README.md

but I assume it will use the textmate grammar when being included by another textmate grammar. Can you confirm if my assumption is correct about using the textmate grammar when included by another textmate grammars,

It is.

and if so which version of the grammar is in use.

The latest SHA of the repo the submodule points to.

Thanks for the confirmations @lildude

I've made the required updates to the edge grammar, so everything should be fine from our end now. I've tested the updated grammar with nova lightshow and all seems to be working great :)

Looking good, just one request: please change the sample for a real-real world sample; this appears to be a "Hello World" type example.

Done 🙂
