Could we have more different color for syntax highlighting?

[pmattei]

Hello

Would it be possible to have some syntax highlighting customization options or an explanation of how to change that?
In particular I would like that my module names have different color than the language keywords.
Enumerated types are also not language keywords so should have different color for me
The code structures could be in different colors, in order to identify the beginning and the end at a glance.
(I think about begin / end or match and |)

Thank

Regards

This is only a problem with the default VSCode theme. The extension doesn't define any colors, only token names.

If you would like your syntax highlighting to use different colors, you need to use a different theme. Either choose one of the other preinstalled themes or install a theme from the marketplace: https://marketplace.visualstudio.com/search?target=VSCode&category=Themes&sortBy=Installs

The syntax isn't currently specific enough for this. Both begin and match are recognized as keyword.other.ocaml:

vscode-ocaml-platform/syntaxes/ocaml.json

Lines 501 to 505 in 35903d7

	{
	"comment": "reserved ocaml keyword",
	"name": "keyword.other.ocaml",
	"match": "\\b(and|as|assert|begin|class|constraint|do|done|downto|else|end|exception|external|for|fun|function|functor|if|in|include|inherit|initializer|lazy|let|match|method|module|mutable|new|nonrec|object|of|open|private|rec|sig|struct|then|to|try|type|val|virtual|when|while|with)\\b(?!')"
	}

If begin and match had different token names, it would still require you to either find or make a theme yourself that supports different colors per language construct.

Thank you for your reply
I thought Ocaml platform had defined the highlighting
I didn't think it was the default of VS Code, sorry
