Syntax coloring/highlighting in the REPL #4223

Open scabug opened 13 years ago

scabug commented 13 years ago

= problem = Currently there is no syntax coloring/highlighting in the REPL.

= analysis = Having syntax coloring/highlighting in the REPL would be very helpful for reading the code, spotting typos and other mistakes.

It would also be a great thing for beginners who are still learning the language and need some visual guidance.

= enhancement recommendation = Add syntax coloring/highlighting to the REPL.

Luigi Plinge (rbj2001) said: Something like they have on StackOverflow would be a lot better than nothing. Their scheme seems pretty simple: keywords dark blue, anything beginning with a capital letter light blue, numbers / anything between quotes or < > dark red, everything else black. (I haven't done more than a few minutes of analysis but this covers all examples I've looked at.)

@soc said: A simple, incremental improvement would be to have colored prompts, so that at least the definition and its results can be visually differentiated.

@puffnfresh said: Sounds like [~retronym] is happy to target the -Dscala.color flag for 2.11 but then change to JLine auto-detection in 2.12 so that we can get feedback on the bikeshed paint before committing to it?

scabug commented 10 years ago

@puffnfresh said: Think I'll write the auto-detection for Typelevel's scalac for our 2.11 compatible release, so we can test it out there.

@retronym said: Sounds GTM. wrt the color choice, it would be important to find defaults that works on dark and light terminals.

Ammonite has it, Dotty has it.
