[Github-comments] [geany/geany] Colon styling in Ruby lexer (#1121)

[Trent McPheron]

I've noticed a peculiarity in regards to how the Ruby lexer styles colons. A literal that starts with a colon is of course a symbol, but colons are used in other contexts as well, most notably for hash literals, like this snippet from the Ruby docs:

`options = { font_size: 10, font_family: "Arial" }`

If you put this in Geany, it will style the colons as symbol literals and not as operators as it should.

This is more important for the Ruby-like static language Crystal, in which the Ruby lexer is almost totally sufficient--aside from the fact it only supports primary keywords and not secondary, class, or type keywords--where this notation is used for named tuples, as well as for type annotation for functions: `def square(n: Int32): Int32'

TL;DR: A colon at the start of a word should indicate a symbol literal, but a colon by itself or at the end of a word should be styled as an operator or punctuation.
