rebar3_oscmd

Run custom shell commands with rebar3 oscmd <shell command>

Purpose

The goal of this plugin is to allow rebar3 to run additional commands via the system shell, so that one can use it solely to manage everything in an Erlang project.

Whether it is bringing Docker containers up, tagging a new Git release or deleting log files, you should be able to use a single build tool.

Note about the fork: this project differs from the original in a few minor ways:

• No uncessary, old, or broken deps
• Latest version of Erlang is supported in CI/CD
• More explicit project name (mostly just to avoid confusion in Hex.pm)

How it works

This is a very simple and straightforward plugin. Simply describe your command in rebar.config and execute (just like you would Linux aliases) with rebar3 oscmd <shell command>.

Usage

Add the plugin to your rebar.config:

    {plugins, [
        {rebar3_oscmd, "0.5.0"}
    ]}.

    {commands, [
        {docker_up, "docker-compose up -d"},
        {sync, "git fetch upstream && git merge upstream/master"}
    ]}.

The example above shows you how to describe a command to bring your Docker containers up, as well as another one to sync a Git repository with remote master.

Some options are available, as described below:

• [{timeout, <Ms>}] (defaults to 15000)
• [{verbose, <Verbose>}] (defaults to false)

e.g. you could change the previous docker_up command to have it fail after 5s with {docker_up, "docker-compose up -d", [{timeout, 5000}]},. You could also get more info from the shell for the above command sync with {sync, "git fetch upstream && git merge upstream/master", [{verbose, true}]}
