ecp

easily build compiler plugins.

Document

Prerequisites

ecp required latest Nightly Rust.

Why use "compiler plugin" instead of "Macros 1.1"?

I need not only "custom derive", but also more "compiler plugin" features. Currently "Macros 1.1" is also unstable.

Usage

Add dependencies to Cargo.toml

toml [dependencies] ecp = "^0.1"

In your main.rs or lib.rs:

```rust

![feature(quote, pluginregistrar, rustcprivate)]

extern crate syntax; extern crate ecp; ```

Examples

Create a simple macro which prints "Hello world!":

```

![feature(quote, pluginregistrar, rustcprivate)]

extern crate syntax; extern crate ecp; use ecp::prelude::*;

[plugin_registrar]

pub fn register(reg: &mut Registry) { reg.register_macro("test", test); }

pub fn test(cx: &mut ExtCtxt, : Span, _: &[TokenTree]) -> Box { MacEager::expr(quoteexpr!(cx, println!("Hello world!"))) } ```
