rosie_ros2_deps

A rebar plugin to fetch ROS packages and repos for ROSIE;

Internally this plugin uses rebar_git_resource to fetch the ROS repositories.

Build

rebar3 compile

How to add a ros package to your rebar3 deps

To fetch a ros package from this list:

% rebar.config

{deps, [ { ros_pkg_name, {ros2, galactic}} ]}.

To fetch a ros package local installed:

% rebar.config

{deps, [ { ros_pkg_name, {ros2, local}} ]}.

How It Works

• The pluging will search for a ros package for the galactic distribution that matches the app name.

• If it finds one, will fetch it's repository.

• It will extract from the repository all the ros interfaces contained in the package directory; than it will parse its package.xml file to discover its dependancies.

• Eventual dependencies will be listed as above in the erlang.config file of the newly generated app. They will also be part of the .app.src to be included in releases.

• The generated app will use this same plugin so that rebar can chain this operations recursively to satisfy any dependancy tree.

• If one dep has a dependancy not listed in the distribution the missing dep is ignored and not added in the rebar.config file; a warning is printed.

• The rebar.config of the generated app will use the rosie_interface_compiler, this will trigger a compilation of all ros interfaces in the app directory.
