Syntax highlighting: symbols about vscode-wolfram HOT 3 CLOSED

A lot of these questions are about VSCode in general, and not this extension specifically, but I will try to respond.

For the side note:

I googled "VSCode customize color theme" and this:

https://code.visualstudio.com/docs/getstarted/themes#_customizing-a-color-theme

may be helpful for you.

It is an open issue for VSCode to enable different themes for different filetypes:

microsoft/vscode#20652

The different colors for UpdateTarget are because the WL syntax highlighting has special handling of function application syntax.

Symbols like foo in foo[] are highlighted different than just foo by itself.

But this does not extend to x // foo syntax because it would be too cumbersome to implement inside the syntax highlighting rules.

It is important to understand that syntax highlighting is only an approximation to the actual semantics of the language.

No real parsing or analysis is being done; only tokens are being examined with regexes.

Attributes is a function and HoldAll is a constant (for lack of a better term for symbols that are not functions). That's why they are colored differently.

Square brackets have different colors because that is what VSCode does:

A very useful command is available on the command palette:

Developer: Inspect Editor Tokens and Scope

This opens a popup where the cursor is and gives information about the currently selected token:

the various scopes and the specific color that it has

Also, it looks like you do not have semantic highlighting enabled.

If you turn on the setting for Wolfram: Semantic tokens, you will see things like Module variables being colored differently and other nice additions.

@bostick Thanks for feedback, indeed after posting I noticed that my problem's nature is mostly vscode related. I will try to come up with a custom theme then.

Yes, I was confused about Module variables as well because I did enable it but maybe something went of in chaos of trying to make it work.

Now I am getting somewhere:

An issue I faced is that I can't distinguish With variables/parameters from function patterns:

Btw, it became a discussion so you can close this issue at any time if you feel like it.

Right, I gave both With variables/parameters and function patterns the scope of variable.parameter.

I could certainly work to give them different scopes, since it seems like you are interested in giving them different colors (I presume).
