How to add keywords for autocompletion?

[erosman]

How can specific keywords be added to JavaScript for autocompletion (and styling)?

The goal is to add Greasemonkey keywords e.g.

'GM_getValue', 'GM_setValue', ... 
'GM.getValue', 'GM.setValue', ...
'unsafeWindow', 'exportFunction', 'cloneInto'

You can use this example as a guide for adding random completion items.

For "dynamic" syntax highlighting you will need to look into the semantic tokens API. Perhaps you can follow-up in #4863 and ask about it over there.

Good luck with your project.
