Crate sourcemap [−] [src]

This library implements basic processing of JavaScript sourcemaps.

Installation

The crate is called sourcemap and you can depend on it via cargo:

[dependencies]
sourcemap = "*"

If you want to use the git version:

[dependencies.sourcemap]
git = "https://github.com/mitsuhiko/rust-sourcemap.git"

This crate can load JavaScript sourcemaps from JSON files. It uses serde for parsing of the JSON data. Due to the nature of sourcemaps the entirety of the file must be loaded into memory which can be quite memory intensive.

Usage:

use sourcemap::SourceMap;
let input: &[_] = b"{
    \"version\":3,
    \"sources\":[\"coolstuff.js\"],
    \"names\":[\"x\",\"alert\"],
    \"mappings\":\"AAAA,GAAIA,GAAI,EACR,IAAIA,GAAK,EAAG,CACVC,MAAM\"
}";
let sm = SourceMap::from_reader(input).unwrap();
let token = sm.lookup_token(0, 0).unwrap(); // line-number and column
println!("token: {}", token);Run
