Surely it’s not just me… Does anyone else feel that the syntax highlighting for Julia on Discourse looks a bit dull compared to other languages? For instance, here’s some simple Julia code: struct Vec{T<:Real} x::T # foo y::T # bar end Base.:+(a::Vec, b::Vec) = Vec(a.x + b.x, a.y + b.y)…

Clear your cache and try again. I believe it should be enabled for all themes.

Thanks. Will post here to not ping everybody on that thread [image] Does everyone's code highlight on Discourse look so bland? Meta Discussion To my knowledge, Fredrik’s branch has not (yet) been upstreamed into highlights.js. It’d be great if it could! Just to be clear…

I prefer “dull” to “so flashy as to hinder readability”. Definitely prefer the way Julia code is highlighted to your JavaScript example, the latter is much less readable to me.

It’s definitely too dull now, imo. I especially dislike that it only seems to highlight some predefined list of types, e.g. foo(x::Real) foo(x::Vec) And zero highlighting here? Base.:+(a::Vec, b::Vec) = Vec(a.x + b.x, a.y + b.y)

[image] DNF: I especially dislike that it only seems to highlight some predefined list of types Agree, special-casing is ugly. However, given that types are normal values in Julia, I think the only choice is not to attempt to treat types differently than other kinds of values.

We could do a poll Is the syntax highlighting of Julia: poll
