duplicate
=============================

[![Build Status](https://api.travis-ci.org/Emoun/duplicate.svg?branch=master)](https://travis-ci.org/Emoun/duplicate)
[![Latest Version](https://img.shields.io/crates/v/duplicate.svg)](https://crates.io/crates/duplicate)
[![Rust Documentation](https://img.shields.io/badge/api-rustdoc-blue.svg)](https://docs.rs/duplicate)

attribute macro for code duplication with substitution.

This document is meant for contributors to the crate. The documentation is hosted at [docs.rs](https://docs.rs/duplicate).

# Testing

This crate uses [macrotest](https://crates.io/crates/macrotest) for testing expansion. 
Therefore, before running tests the nightly compiler must be installed together with `rustfmt` and `cargo-expand`:

```
cargo install cargo-expand
rustup toolchain install nightly
rustup component add rustfmt
```

The tests can then be run as any other tests:

```
cargo test
```

# Formatting

We use `rustfmt` to manage the formatting of this crate's code.
To have cargo format the code for you, you must have the nightly compiler installed (but not necessarily the default) and then run the command:

```
cargo +nightly fmt
```

Travis-CI will check the formatting and fail if it isn't formatted correctly.

# Release Deployment

Deployment of new versions of this crate is managed by Travis-CI using git tags. 
To trigger a new release, simply push a tag to the repository containing only the version number:

```
git tag 1.0.0
git push --tags
```

We do not use the `Cargo.toml` to manage the versioning of this crate.
The version given in it should not be changed! 
It must remain as `0.0.0` so Travis-CI can correctly change it for every release.
