[lit]: source maps #12
Description
Is your feature request related to a problem? Please describe.
Currently the parser doesn't provide any source maps. This causes trouble in downstream tools like Jest when it comes to line numbers. Test results don't point to the right line number and column
Describe the solution you'd like
If the parser properly provided source maps I believe this issue would be resolved
Describe alternatives you've considered
It wouldn't be possible to make the parser output files of the same number of lines as the /** jsdoc comment already adds extra lines and is a feature I don't wanna break
Additional context
I think creating the source map shouldn't be too difficult with https://github.com/mozilla/source-map
as far as plugging that into Babel I am confused. You can tell babel to make source maps https://babeljs.io/docs/en/options#inputsourcemap
but I don't know how to tell it I made source maps for a file I parsed
https://github.com/talon/javascript-registry/blob/master/packages/lit/lib/babel.js#L43
typescript I'm pretty sure does this so maybe that repo would help maybe
