Following our short discussion, I'm reposting here:
I just tried opening a Julia project, here are some quick comments (I could make those in your repo if you preferred):

--> ideally the :name should be highlighted as strings, the const keyword should be highlighted too as well as function indicators (like LittleDict) though that last one matters less. Also the nothing, false, etc keywords

--> keywords like function, if, end, etc should be highlighted, functions should ideally be highlighted, modules (e.g. Base. and Core. should too + missing keyword

--> text between """ should be highlighted as string, #= ... =# indicates a multi-line comments
I could give you more detailed feedback on this at the main repo if that's useful?
Note: I think the most up to date description of the syntax is in highlights.js (https://github.com/highlightjs/highlight.js/blob/master/src/languages/julia.js)

Thanks. lexer was updated now.
please check it again?

that looks great! and I understand for the font, I'll adjust, thanks!
I just updated it (update in Plugins/ Addon Manager/ update).
so that julia.js keywords are all used now.
I was not sure how to highlight these words from this line
{
className: 'keyword',
begin:
'\\b(((abstract|primitive)\\s+)type|(mutable\\s+)?struct)\\b'
},
this shows words: abstract, primitive, type, mutable, struct. how to highlight them?
the same way:

that was added, lexer updated. I leave the issue opened for few days (maybe you 'll comment).
@tlienart It will be good if you annouce that lexer for Cud was reworked. i made lot of changes today. I mean at https://discourse.julialang.org/t/is-anyone-using-textadept-as-their-editor-of-choice-for-julia/41255/1
done :-)
thanks; closing.
