YAML error messages are not helpful #8

Open evanmiller opened 7 years ago

evanmiller commented 7 years ago

I have a project with ~50 templates. There's an error somewhere in a YAML snippet, but all Uzu tells me is:

Couldn't parse YAML
  in sub build at /Users/emiller/Code/rakudo/install/share/perl6/site/sources/B64B70030D8DC8D24494E45C38BA972A87CF0732 (Uzu::Render) line 267

I would like to know what file is failing, and (ideally) on what line number the parse fails.

Hi @evanmiller, I have added a catch to spit out the template name that it dies on for now. I am going to look into a solution for validating the yaml before trying to parse it. YAMLish doesn't support this yet.

Uzu will still die, but you should now see a message like this:

Invalid template yaml [/example_project_tt/pages/index.tt]

Thanks, much better! I will leave this open until line numbers are provided.
