Replace singleline comments with `//` or `/*...*/`, and also multi-line comments in json files.

ECMAScript (JavaScript)
This has been validated against a tsconfig.json file that i'm using and nothing else. It should work fine though. You can use this to replace comments with vscode find and replace, but using the regex in the search field, and '$2' without quotes in the replace field.

Description

Pattern for matching actually valid RGB values.

  • validate separator (mixing spaces and commas between values is not valid)
  • validate if comma is used as separator if alpha channel is set
  • validate units (mixing percentage with integers is not valid)
  • extract r, g, b, a, separator and unit with named groups
