Pomsky

To learn about the pomsky language, please read the book.

The pomsky macro can be found here.

Usage

This library can parse a pomsky expression and generate a regex string:

use pomsky::Expr;
use pomsky::options::{CompileOptions, RegexFlavor};

let options = CompileOptions { flavor: RegexFlavor::Java };
let (regex, _warnings) = match Expr::parse_and_compile("'test'", Default::default(), options) {
    Ok(regex) => regex,
    Err(_) => {
        eprintln!("The input is not a valid pomsky expression");
        return;
    }
};

You can get fancy error messages with miette by enabling the diagnostics feature:

use pomsky::Expr;
use pomsky::options::{CompileOptions, RegexFlavor};
use pomsky::error::Diagnostic;

pub fn compile(input: &str) -> miette::Result<String> {
    let options = CompileOptions { flavor: RegexFlavor::Java };
    let (compiled, _warnings) = Expr::parse_and_compile(input, Default::default(), options)
        .map_err(|e| e.diagnostic(input))?;
    Ok(compiled)
}
