Preserve backslash in regexp #375

Closed mhaagens closed 6 years ago

Any way I can preserve the backslash in the regexp of "test", as seen here? It just returns test: /.js$/ when I run it through parseModule.

That's a normal JavaScript string escaping thing, nothing to do with Shift. By the time Shift sees it, there's no backslash there:

`\.` === '.' // true

Just put another backslash in front of it, or tag your template with String.raw.

Thank you so much for helping me out, and sorry for opening an unrelated issue!
