Error messages the compiler currently prints could be nicer:

  • Colorize code that has an error (when it isatty)
  • Suggest possible solutions
  • Link to a relative docs
  • Structured error codes

Any more ideas?

We could learn many things about this topic from the Elm compiler.

I think it is nice to see an informative error message when the required field is missing on package.toml.

$ nirum -t docs -o ./out/docs/ .
Metadata error: FieldError "targets.docs.title"
