❔ Writing VS Extension to Support Language with TextMate Grammar File

Hello, I am trying to write extension to support BNF(Backus–Naur form) metalanguage files. I am trying to add Syntax Highlight. I find this https://www.youtube.com/watch?v=ftug7sL-5kw but it doesn't seem to work for me. My best ques is that I have a something wrong in tmLanguage file. I added only comments (one line). To what I understood the name should define the style, I used just comment thinking that it will make my comments green like they are in my VS Theme. I didn't find the tmTheme definition for the defaults VS Themes if anybody found them, that might be helpfull. Here is my tmLanguage file:

! as a 1st character in regex has a special meaning. I never heard about that VS regex dosn't use it either. If an exclamation mark (!) occurs as the first character in a regular expression, all magic characters are treated as special characters. An exclamation mark is treated as a regular character if it occurs anywhere but at the very start of the regular expression.

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
