Allow interpolation coloring in template literal strings when using new JS/TS grammar

[waderyan]

• VSCode Version: 1.7.0 (or pre-1.7 with new grammar extension)
• OS Version: Windows 10

Steps to Reproduce:

1. Write a template literal string with interpolation: `test ${var}`
2. Before the new grammar was introduced, interpolation received special coloring
3. Post new grammar, interpolation is colored the same as the rest of the string

Personally, I find this far less readable when scanning template strings; I have to look more carefully than before to pick out where I'm interpolating an expression. Is there a way we can return the old coloring while respecting the new design decisions behind the grammar rewrite?

this is what i see now:

what is the desired behavior?

The desired behavior colors the interpolation tags to be blue:

Hey,

Believe I am seeing what @waderyan is seeing (image below) in a pure JS project on MacOS 10.12.1 running VSCode 1.7.1.

Thanks

There was already microsoft/vscode#13166 to track this which seems to be closed. @aeschli can you please take a look and see whats going on here. Our grammar has already scoped out the punctuations.. is there something I am missing

I pushed a fix for VSCode. See microsoft/vscode#13166. Ok to close.
