I think it would be difficult.

Racket has macros, and it allows shadowing on anything. The attached image
shows how `(if 1 2 3)` is colored differently by Check Syntax due to the
interaction with macros and shadowing.

[image: Screen Shot 2020-10-10 at 10.07.00.png]

To identify which context `(if 1 2 3)` is in, you need to macro-expand the
program and then analyze the expanded program (this is exactly what the
Check Syntax button does). However, macro expansion could be very
expensive. Syntax highlighting on the other hand is supposed to be very
cheap and done immediately as you edit the program. I believe this is why
DrRacket doesn't support syntax highlighting that you described.

If you are OK with a delay (you type something and it's colored, say, 10
seconds later), I think it's possible to use the result from the online
Check Syntax, which macro-expands your program continuously in the
background, to color the program.

Looks interesting. Do you know any package of this type for DrRacket (or
another program) that works semantically while you program? (not just as a
checking tool like View Syntax)

Re: [racket-users] Clearer code in DrRacket?

[Shu-Hung You]

Here is an example that provides different colors for some particular
forms such as define, require, lambda etc. However, these forms
('keywords') are recognized literally by the lexer instead of
semantically as in Check Syntax. Therefore it will classify
non-keywords as keywords from time to time.

The colors of most things in DrRacket are adjustable: see Preferences in 
the Edit menu.  There are several general color schemes and/or you can 
set colors individually for most syntax items.


Note that there are multiple (2nd level) tabs under Color [and also 
under Editing].

Re: [racket-users] Clearer code in DrRacket?

[Sam Tobin-Hochstadt]

If you'd like to see different colors for imported identifiers, then
you can click the "Check Syntax" button in DrRacket. The attached
picture shows what it looks like.

Note that there's not a difference between `cons` and `null?` because
those are both functions.

You can adjust the particular colors chosen in the Preferences dialog,
under the Check Syntax tab.

Can you give an example of which things you'd like to be different? We
usually use "variable" and "identifier" for very similar meanings when
discussing Racket, for example.

[racket-users] Clearer code in DrRacket?

[Adam El Mazouari]

Hello everyone.

I've started using DrRacket a couple of weeks ago and I can't get used to 
the color theme. Variables, identifiers, methods, all of them are in blue. 
It's really unintuitive. Does anybody know a good plugin that 
differentiates these in a clear way for the human eye? 

Or, if you know something better than DrRacket in that regard, feel free to 
write down.

Thanks in advance!
