rebar ===== rebar is an Erlang build tool that makes it easy to compile and test Erlang applications, port drivers and releases. [![Build Status](https://travis-ci.org/tsloughter/rebar.svg?branch=rebar3)](https://travis-ci.org/tsloughter/rebar) rebar is a self-contained Erlang script, so it's easy to distribute or even embed directly in a project. Where possible, rebar uses standard Erlang/OTP conventions for project structures, thus minimizing the amount of build configuration work. rebar also provides dependency management, enabling application writers to easily re-use common libraries from a variety of locations (git, hg, etc). 3.0 ==== This is an experimental branch. ### Commands | Command | Description | |----------- |------------ | | compile | Build project | | clean | Remove project apps beam files | | ct | Run Common Test suites | | do | Higher-order provider to run multiple tasks in sequence | | help | Print help for rebar or task | | new | Create new rebar project from templates | | pkgs | List available packages | | release | Build release of project | | tar | Package release into tarball | | shell | Run shell with project apps in path | | update | Update package index | | upgrade | Fetch latest version of dep | | version | Print current version of Erlang/OTP and rebar | The following commands are still in the works. | Command | Description | |----------- |------------ | | eunit | | ### Changes * Fetches and builds deps if missing when running any command that relies on them * Automatically recognizes `apps` and `libs` directory structure * `escriptize` requires `escript_top_level_app` set in `rebar.config` * Relx for releases ### Gone * Reltool integeration ### Providers Providers are the modules that do the work to fulfill a user's command. Example: ```erlang -module(rebar_prv_something). -behaviour(rebar_provider). -export([init/1, do/1]). -define(PROVIDER, something). -define(DEPS, []). %% =================================================================== %% Public API %% =================================================================== -spec init(rebar_state:state()) -> {ok, rebar_state:state()}. init(State) -> State1 = rebar_state:add_provider(State, rebar_provider:create([{name, ?PROVIDER}, {module, ?MODULE}, {bare, false}, {deps, ?DEPS}, {example, "rebar dummy"}, {short_desc, "dummy plugin."}, {desc, ""}, {opts, []}])), {ok, State1}. -spec do(rebar_state:state()) -> {ok, rebar_state:state()}. do(State) -> %% Do something {ok, State}. ``` Building -------- Information on building and installing [Erlang/OTP](http://www.erlang.org) can be found [here](https://github.com/erlang/otp/wiki/Installation) ([more info](https://github.com/erlang/otp/blob/master/INSTALL.md)). ### Dependencies To build rebar you will need a working installation of Erlang R13B03 (or later). Should you want to clone the rebar repository, you will also require git. #### Downloading You can download a pre-built binary version of rebar from: https://github.com/rebar/rebar/wiki/rebar #### Building rebar ```sh $ git clone git://github.com/rebar/rebar.git $ cd rebar $ ./bootstrap/bootstrap Recompile: src/getopt ... Recompile: src/rebar_utils ==> rebar (compile) Congratulations! You now have a self-contained script called "rebar" in your current working directory. Place this script anywhere in your path and you can use rebar to build OTP-compliant apps. ``` Contributing to rebar ===================== Please refer to [CONTRIBUTING](CONTRIBUTING.md).
