Crate media_query_parse 

A pure-Rust parser for the CSS Media Queries grammar.

Tokenizer (CSS Syntax Level 3) plus a Media Queries Level 4 grammar/AST/parser, including the <mf-range> comparison syntax. See plan/ for the roadmap.

Example

use media_query_parse::{parse_media_query, parse_media_query_list};

// A single, syntactically valid media query.
assert!(parse_media_query("screen and (min-width: 400px)").is_ok());

// An invalid media query reports a `ParseError` instead of panicking:
// `only` requires a following `<media-type>`, which is missing here.
assert!(parse_media_query("only").is_err());

// `parse_media_query_list` splits a comma-separated list and parses
// each entry independently, returning one `Result` per entry.
let results = parse_media_query_list("screen, only");
assert!(results[0].is_ok());
assert!(results[1].is_err());
