Very nice but for one feature

This is fantastically useful, very well-made tool even in its first version. There’s only one critical feature missing that would be great to add ASAP: debug messages report line numbers that have errors (e.g. missing comma in JSON) but source file doesn’t show line numbers, and there’s no way to make it do so, which makes debugging unnecessarily painful.

Please add that feature and it will be perfect.

Thanks!
