# ip-macro [![Build status](https://api.travis-ci.org/lfairy/ip-macro.svg)](https://travis-ci.org/lfairy/ip-macro) [![Cargo](https://img.shields.io/crates/v/ip-macro.svg)](https://crates.io/crates/ip-macro) Macros for writing literal IP addresses. See <https://github.com/rust-lang/rfcs/issues/1926> for the background behind this crate. ## Rust nightly This crate uses the recently implemented [procedural macros] feature, and so requires a nightly version of the compiler. If you use [rustup][] (recommended), then you can install Rust nightly using [these instructions][nightly howto]. [procedural macros]: https://github.com/rust-lang/rust/issues/38356 [rustup]: https://rustup.rs/ [nightly howto]: https://github.com/rust-lang-nursery/rustup.rs#working-with-nightly-rust ## Example ```rust #![feature(proc_macro)] // <- Don't forget this!!! extern crate ip_macro; use ip_macro::ip; fn main() { println!("There's no place like {}", ip!("127.0.0.1")); } ```
