If I try to add a keyword in filetypes.langage.conf who start by the symbol, @, he will not be colored. For example, the Zig language use builtins function who start by @, but I can't color them. I used C coloration as base for custom Zig coloration, but with Rust lexer and tag parser, maybe a ctag problem ? I don't know. I join my configuration file if you want to try. [filetypes.ZigBasicSupport.zip](https://github.com/geany/geany/files/14948356/filetypes.ZigBasicSupport.zip) And also, is it possible to define a coloration for every u or i followed by a number ? Zig can use them to specify any size of integer.
