I’ve been working on a new vs code exention for MEL (Medical Expression Lanaguage) and I’m running into some issues with it not working with uppercase Syntax. Most of the existing code has uppercase syntax and I would love to be able to copy and paste it into vs code and have syntax highlighting. I’ve been creating an extension to do just that but I’m running into an issue where is it is highlighting the syntax but only if it is completely lowercase. Here are my yo code files:

mel.tmLanguage.json

{
    "$schema": "https://raw.githubusercontent.com/martinring/tmlanguage/master/tmlanguage.json",
    "name": "Mel",
    "patterns": [
        {
            "include": "#keywords"
        },
        {
            "include": "#strings"
        }
    ],
    "repository": {
        "keywords": {
            "patterns": [{
                "name": "keyword.control.mel",
                "match": "/b(IF|if|then|THEN|ELSE|else|EndIf|ENDIF|FOR|for|COND|cond|CASE|case|ENDCOND|endcond|EndFor|ENDFOR|While|while|endWhile|ENDWHILE|Do|do)b/"
            }]
        },
        "strings": {
            "name": "string.quoted.double.mel",
            "begin": """,
            "end": """,
            "patterns": [
                {
                    "name": "constant.character.escape.mel",
                    "match": "\\."
                }
            ]
        }
    },
    "scopeName": "source.mel"
}

package.json

{
  "name": "mel",
  "displayName": "MEL Language Support",
  "description": "Medical Expression Language Support",
  "version": "0.0.1",
  "engines": {
    "vscode": "^1.89.0"
  },
  "categories": [
    "Programming Languages"
  ],
  "contributes": {
    "languages": [{
      "id": "mel",
      "aliases": ["Mel", "mel"],
      "extensions": [".mel"],
      "configuration": "./language-configuration.json"
    }],
    "grammars": [{
      "language": "mel",
      "scopeName": "source.mel",
      "path": "./syntaxes/mel.tmLanguage.json"
    }]
  }
}

Any suggestions will be helpful, I’m honestly completely stuck and not sure why this isn’t working. thank you in advance 🙂 If you need any other files just lmk please.
