# sourcemap
This library implements basic processing of JavaScript sourcemaps.
## Installation
The crate is called sourcemap and you can depend on it via cargo:
```toml
[dependencies]
sourcemap = "*"
```
If you want to use the git version:
```toml
[dependencies.sourcemap]
git = "https://github.com/getsentry/rust-sourcemap.git"
```
## Basic Operation
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:
```rust
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);
```
## Features
Functionality of the crate can be turned on and off by feature flags. This is the
current list of feature flags:
* `ram_bundle`: turns on RAM bundle support
