lexer
A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.

It would be nice if subpatterns could be used within subpatterns.
#[derive(Logos, Copy, Clone, Debug)]
#[logos(subpattern a = r"[a-zA-Z!$%&*/:<=>?^_~]")]
#[logos(subpattern b = r"(?&a)|[0-9+\-.@]")]
pub enum Token {
#[error]
Error,
// ...
}Currently, this is not supported and causes a regex parse error.
Prepare the parser to PHP 8 :

Would it be possible to have the regex parser support character classes like \w within other character classes? I had a regex pattern earlier that used the character class [0-9a-zA-Z_\.-], and I attempted to simplify it with [\w\.\-]. I didn't notice this library doesn't support doing that, and was wondering just how difficult that would be to implement. For the time being i'm just expanding

Example, we'd want something like:
foo #(
.aaaa(111), // this line
.bb (22) // and this line
) bar (
.xx(x),
.y (yy)
);Two-columns should be sufficient, just aligning on the ( on each parameter.
This implementation should be very similar to named port connections of instances (also in the above example).
