Module syntax 

Syntax highlighting described by a config file, one per language.

A language file is a flat list of key value lines read by kv_parser:

extensions rs
line_comment //
block_comment /* */ nested
strings " \
keywords fn let mut if else match impl pub struct
types u8 u32 usize String Vec Option Result

Every key is optional. Syntax::spans scans a text once and reports what it found; picking colours for the Classes is left to the frontend.

Structs

Enums

Class

Error

Why a language file could not be read.

Functions

directory
