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.

#[logos(subpattern b = r"(?&a)|[0-9+\-.@]")]
pub enum Token {
#[error]
Error,
// ...
}Currently, this is not supported and causes a regex parse error.

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
For fun, I'd like to create an animated demo of formatting (or any text transformation):
Script Input for producing text images:
- A batch of (unformatted) text files
- Any transformation command, like sed
- Some configuration of how to render text (font, size, foreground/background color) as an image
Input for animation:
- Configuration of duration for each image (before/after trans
