Glue is a parser combinator framework for parsing text based formats, it is easy to use and relatively fast too.
Use the test method to see if your input matches a parser:
use glue::prelude::*;
if take(1.., is(alphabetic)).test("foobar") {
println!("One or more alphabetic characters found!");
}
Use the parse method to extract information from your input:
use glue::prelude::*;
assert_eq!(take(1.., is(alphabetic)).parse("foobar"), Ok((
ParserContext {
input: "foobar",
bounds: 0..6,
},
"foobar"
)))
Write your own parser functions:
use glue::prelude::*;
#[derive(Debug, PartialEq)]
enum Token<'a> {
Identifier(&'a str),
}
fn identifier<'a>() -> impl Parser<'a, Token<'a>> {
move |ctx| {
take(1.., is(alphabetic)).parse(ctx)
.map_result(|token| Token::Identifier(token))
}
}
assert_eq!(identifier().parse("foobar"), Ok((
ParserContext {
input: "foobar",
bounds: 0..6,
},
Token::Identifier("foobar")
)));
