I will have a look at it again in the afternoon 🙂

	injection-regex = "umka"

Do you know if the language provides a formatting or lsp program?

While we only require highlights.scm queries for a new language it would be great to have as many of the other queries we use supported as well. I do not know anything about the language at all, but played a bit around with adding rainbows.scm queries to it.

[
  (literal)
  (builtinCallFmt)
  (qualIdent)
  (constDecl)
  (rcvSignature)
  (parameterList)
  (switchStmtDisambiguated)
  (exprSwitchStmt)
  (builtinCallBasic)
  (fullVarDecl)
  (typeOf)
  (block)
  (functionCall)
  (builtinCallMake)
  (returnType)
  (import)
] @rainbow.scope

[
  "{" "}"
  "(" ")"
  "[" "]"
] @rainbow.bracket

I do not think I have covered all the language constructs. If you put it in runtime/queries/umka/rainbows.scm and do HELIX_RUNTIME=$PWD/runtime hx file.um you can see it in effect. Could you go over it and add remaining patterns missing? I have not covered enums and map/index literals, and probably some I am not aware about.
