#  [![Stand With Ukraine](https://raw.githubusercontent.com/vshymanskyy/StandWithUkraine/main/badges/StandWithUkraine.svg)](https://stand-with-ukraine.pp.ua) rust-bundler-cp

This project is based on [rust-bundler](https://github.com/slava-sh/rust-bundler/)

Creates a single-source-file version of a Cargo package. It's designed for Competitive Programming like Codeforces.

## Features

* Uses [Syn](https://docs.rs/syn/latest/syn/) to parse and manipulate a complete syntax tree, instead of doing replacement with regular expression.  

* Replaces `extern crate my_lib;` in `main.rs` with the contents of `lib.rs`.

* Expands `mod my_mod;` declarations into `mod my_mod { ... }` blocks.

* [rustfmt](https://github.com/rust-lang/rustfmt) needs to be available in `PATH`, i.e. `dnf install rustfmt`. I'll consider bundle `rustfmt` in my code later.

* Unsupported: External `[dependencies]` in `Cargo.toml`  

## Example

 

[Endle's codeforces template](https://github.com/Endle/rust_codeforce_template) is co-evoloved with [rust-bundler-cp](https://github.com/Endle/rust-bundler-cp), and is considered as the example of it.  

## Usage

Install:

```sh

$ cargo install rust_bundler_cp

```

Run:

```sh

$ rust_bundler_cp --input path/to/project >output.rs

$ rust_bundler_cp --input path/to/project --binary a

```
