Julia: Syntax highlighting in the REPL?

[Aerlinger]

I wanted to submit a pull request for this, but first wanted to get some feedback on how useful syntax highlighting in the REPL would be to other developers. Personally, I find it very useful for readability, especially when giving demonstrations or taking screenshots.

I would certainly like that :+1

I really like syntax highlighting wherever possible, I don't think you're going to find any pushback against the idea itself, so submitting a PR is a good idea. :)

[StefanKarpinski]

Yeah, this would be very cool so if someone wants to tackle it, that would be great.

I would like to see this for example for the "less" function output. For example:
less(+,(Int, Int))

[ufechner7]

Would it make sense to create a separate issue for syntax highlighting of the output of "less"?

[mbauman]

That's actually something that could probably be resolved quite simply and outside of Julia. The less() function/macro punt to run($(get(ENV, "PAGER", "less")) +$(line)g $file). So if your $PAGER and terminal support syntax highlighting it'll just work. I think. Some breadcrumbs here: http://stackoverflow.com/questions/5316360/syntax-highlighting-pager

FWIW https://github.com/KristofferC/OhMyREPL.jl provides syntax highlighting for the REPL.

Seems unlikely to happen in Base.
