rust-bundler-cp

This project is based on rust-bundler

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

I'm using rust-bundler-cp with my codeforces template https://github.com/Endle/rust_codeforce_template,

Features

• Uses 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 needs to be available in PATH, i.e. dnf install rustfmt. I'll consider bundle rustfmt in my code later.

Example

Input:

// src/internal.rs:
pub fn hello_world() {
    println!("Hello, world!");
}

// src/lib.rs:
mod internal;
pub use internal::hello_world;

// src/main.rs:
extern crate example;
fn main() {
    example::hello_world();
}

Output:

mod internal {
    pub fn hello_world() {
        println!("Hello, world!");
    }
}
pub use internal::hello_world;
fn main() {
    hello_world();
}

More examples in tests/testdata.
