rebar3_otp_install_plugin

A rebar3 plugin for installing OTP applications

Description

This plugin makes it possible to restore the OTP bundle as it looked before OTP-20, i.e. the applications that have been moved out of the OTP repository can be installed into /usr/local/lib/erlang/lib/ or $HOME/.local/lib/erlang/lib or any other suitable place where erl can find them again.

The decoupled applications are proper rebar3 applications, but since they are used in legacy project, this plugin is provided to allow continued use without converting the projects to using rebar3 for packaging.

The plugin is implemented in the otp namespace.

Build

$ rebar3 compile

Usage

rebar3 otp install [<app>] [-r <repo>] [-v <version>] [-t <tag>]
                      [-r <ref>] [-b <branch>] [-o <target>]
                      [--nodeps]

<app>          The application to install. If not given, the application
               found in the current directory is installed.
-r, --repo     Git repository to fetch application from. Default is the
               official erlang/OTP repository for the given application.
-v, --version  Application version. Default is the latest from master
               branch.
-t, --tag      Git tag for application. Default is the latest from
               master branch.
-r, --ref      Git ref for application. Default is the latest from
               master branch.
-b, --branch   Git branch for application. Default is master.
-o, --target   Directory where the apps shall be installed. A
               subdirectory named erlang will be created under the given
               target directory. Default is $HOME/.local/lib.
--nodeps       Install only the primary application, no dependecies.

Example

Add the plugin to your rebar config (typically your global config $HOME/.config/rebar3/rebar.config):

{plugins, [{rebar3_otp_install_plugin,
            {git, "[e-mail]:erlang/rebar3_otp_install_plugin.git",
             {tag, "0.1"}}}
          ]}.

Then just call your plugin directly in any directory:

$ rebar3 otp install typer -v 0.9.13
  ===> Compiling rebar3_otp_install_plugin
  ===> Verifying dependencies...
  ===> Verifying dependencies...
  ===> Fetching typer ({git,"[e-mail]:erlang/typer.git",
                                   {tag,"0.9.13"}})
  ===> Fetching rebar3_appup_plugin ({pkg,<<"rebar3_appup_plugin">>,
                                             <<"2.2.0">>})
  ===> Downloaded package, caching at ....
  ===> Compiling rebar3_appup_plugin
  ===> Compiling rebar3_otpdoc_plugin
  ===> Compiling typer
  ===> Compiling typer.appup.src
  ===> Building escript...
  ===> Installing applications: [typer]

or inside a OTP application directory:

$ rebar3 otp install
  ===> Verifying dependencies...
  ===> Compiling typer
  ===> Compiling typer.appup.src
  ===> Building escript...
  ===> Installing application from current project
  ===> Installing applications: [typer]

Make sure that you start your erlang node with additional paths to installed libs and executables.
