cargo-snippet

A snippet extractor for competitive programmers.

You can manage code snippet with test and bench !!

Installing

You need nightly rust.

$ cargo install cargo-snippet --features="binaries"

Usage

Create a project for snippet.

$ cargo new mysnippet

Add dependencies to Cargo.toml.

toml [dependencies] cargo-snippet = "0.1"

Add this to src/lib.rs.

```rust

![feature(plugin)]

![plugin(cargo_snippet)]

```

Write some snippet codes and tests.

```rust

![feature(plugin)]

![plugin(cargo_snippet)]

// Annotate snippet name

[snippet = "mymath"]

[snippet = "gcd"]

[allow(dead_code)]

fn gcd(a: u64, b: u64) -> u64 { if b == 0 { a } else { gcd(b, a % b) } }

// Also works

[snippet(name = "mymath")]

[allow(dead_code)]

fn lcm(a: u64, b: u64) -> u64 { a / gcd(a, b) * b }

[test]

fn testgcd() { asserteq!(gcd(57, 3), 3); }

[test]

fn testlcm() { asserteq!(lcm(3, 19), 57); } ```

You can test.

$ cargo test

Extract snippet !

``` $ cargo snippet snippet gcd #[allow(dead_code)] fn gcd(a: u64, b: u64) -> u64 { if b == 0 { a } else { gcd(b, a % b) } }

snippet mymath #[allow(deadcode)] fn gcd(a: u64, b: u64) -> u64 { if b == 0 { a } else { gcd(b, a % b) } } #[allow(deadcode)] fn lcm(a: u64, b: u64) -> u64 { a / gcd(a, b) * b } ```
