I'm working on project that implements PaperJS library and I want to add syntax highlighting. From my understanding, I need to modify the ***html.json*** file of VSCode located in the following path: 
`C:\Users\user\AppData\Local\Programs\Microsoft VS Code\resources\app\extensions\html\syntaxes`

When I went to that folder, two different JSON files were there: ***html.tmLanguage*** and ***html-derivative.tmLanguage***. I checked out the initial file and found what seemed to be the right place to edit the code according to Perry Dyball answer in this question thread: [Visual Studio Code: Paperscript](https://stackoverflow.com/questions/44256968/visual-studio-code-paperscript).

However, the lines of code to edit are full of `\t`:

I expected to be able to add syntax highlighting for PaperJS by modify this JSON file according to Perry Dyball's answer for the question thread mentioned in this post, but I am conflicted on the way to do that and there seems to be no answer online for the different file names or the lines full of `\t`.
