# rust-sourcebundler

Bundle the source code of a rust cargo crate in a single source file.

Very useful for sending the source code to a competitive programming site that

accept only a single file ([codingame](https://codingame.com), I'm looking at

you) and still keeping the cargo structure locally.

## Usage

Add the following snippet to your *Cargo.toml*:

```toml

[package]

(...)

build = "build.rs"

[build-dependencies]

rustsourcebundler = { git = "https://github.com/lpenz/rust-sourcebundler" }

```

And create the file *build.rs* with the following:

```rust

//! Bundle mybin.rs and the crate libraries into singlefile.rs

use std::path::Path;

extern crate rustsourcebundler;

use rustsourcebundler::Bundler;

fn main() {

    let mut bundler: Bundler = Bundler::new(Path::new("src/bin/mybin.rs"),

                                            Path::new("src/bin/singlefile.rs"));

    bundler.crate_name("");

    bundler.run();

}

```

You can use the code inside the *example* directory of this repository

as a starting point.
