More useful parser-combinators for nom.

WARNING! This project is still in development.

If a parser looks useful, it may be more practical to copy it to your project.

To add this library to your project run:

cargo add snacks

combinators

find all

Run the parser at each found substring.

let input = "This is a {text} with some {special} {words}!";
let result = find_all::<_, _, _, nom::error::Error<_>>(
    "{",
    delimited(char('{'), alphanumeric1, char('}')),
)(input);
assert_eq!(Ok(("!", vec!["text", "special", "words"])), result);

find_all_into This method can be used to push the items into a buffer, for saving allocations.

recognize separated

Runs the item parser interlaced by the separator parser.

The main difference to the separated_list0 parser from nom is, that this parser returns the recognized string without allocating a list.

let input = "comma,separated,words other";
let result = recognize_separated0::<_, _, _, nom::error::Error<_>>(alphanumeric1, char(','))(input);
assert_eq!(Ok((" other", "comma,separated,words")), result);

take all

Takes the items from the item parser, preceded by a prefix parser.

let input = "An example #sentence with #cool tags!";
let result = take_all::<_, _, nom::error::Error<_>>(
    is_not("#"),
    preceded(one_of("#"), is_not(" ")),
)(input);
assert_eq!(Ok((" tags!", vec!["sentence", "cool"])), result);

take_all_into This method can be used to push the items into a buffer, for saving allocations.

values

Takes a link from the input.
