# 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("<crate name>");
    bundler.run();
}
```

You can use the code inside the *example* directory of this repository
as a starting point.
