This project is free and open-source under the MIT license. Anyone can fork this repository and submit a pull request, however all pull requests are subject to review and approval by this project's authors. All merged code becomes part of this project, and thus is subject to the same license as the rest of the code in this project. Any code in this repository may be deleted, modified, or rewritten at any time. Ultimately the authors of this project, the Florida Space Institute, and NASA have final control over this project's code. By submitting a pull request, you voluntarily surrender all the rights you possess over your code to the Florida Space Institute, NASA, and the authors of this project (with the good-faith expectation that your contributions will be adequately credited to you). New authors may be named periodically, depending on contribution size and project demands.

DEVELOPMENT INSTRUCTIONS

Before you begin developing, you must first install ROS and the ROS build tools (these instructions are in the `readme`_). Clone the repository with the following command:

git clone https://github.com/FlaSpaceInst/EZ-RASSOR.git
cd EZ-RASSOR

The next thing you should do is install the dependencies for all of the packages in this repository, which can be done using the develop.sh script like so:

sh develop.sh setup
sh develop.sh link
sh develop.sh resolve
** RESTART TERMINAL **

Finally, you'll need to get familiar with the develop.sh script, which is designed to help developers improve this software with ease. This script is intended to completely wrap Catkin and this project's ROS workspace. It is important that you use this script instead of making changes to the workspace or calling Catkin directly. Read the script if you want gory details about how it works.

Its general syntax looks like this:

sh develop.sh <mode> [arguments...]

The modes supported by the script are listed below:

setup

Set up a Catkin workspace in your home directory to develop and compile ROS nodes. This workspace is named .workspace by default. This mode also sources the new workspace's build directory in your shell's configuration files.

new <superpackage> <package> [dependencies...]

Create a new ROS package in the packages folder, under the appropriate superpackage. If the superpackage doesn't exist it is created. All arguments after package are passed to catkin_create_pkg (these arguments are usually dependencies of the package). The newly created package is then symlinked into your workspace's src folder. If you've never run setup ensure that you do that before trying to make a new package, otherwise you won't have a workspace to develop in!

link [-e, --except <packages...> | -o, --only <packages...>]

Create a symlink from all packages in the packages directory to the src directory of your workspace (so that you can build and test your software, without having to copy it into the workspace each time). You should execute this mode after creating a new workspace, or if you've renamed/reorganized the packages in packages. If you've done this, you'll want to purge before running this command (see below), otherwise your src directory could contain broken symlinks to removed/renamed packages. Exclude specific packages with the -e or --except flag. Link specific packages with the -o or --only flag.

purge

Remove all symlinked packages from src.

relink [-e, --except <packages...> | -o, --only <packages...>]

Purge all symlinked packages from src, and then link all packages in packages. Ignore specific packages with the -e or --except flag. Relink specific packages with the -o or --only flag.

resolve

Install all required dependencies for currently linked packages.

build

Call catkin_make in your workspace.

install

Install all built packages into the install target in your workspace (via catkin_make install).

kill

Kill all running ROS nodes and roscore.

test

Run integration tests for all linked packages.

reversion <version>

Update the version of every package in this repository.

Here are some example commands to get started.

# Set up a new Catkin workspace.
sh develop.sh setup

# Create a new package in the superpackage 'autonomy' called 'ezrassor_swarm'.
sh develop.sh new autonomy ezrassor_swarm

# Link only your new package and 'ezrassor_launcher', plus install dependencies.
sh develop.sh link --only ezrassor_swarm ezrassor_launcher
sh develop.sh resolve

# Build your linked packages.
sh develop.sh build

# Something went wrong... relink all packages except 'ezrassor_swarm'.
sh develop.sh relink --except ezrassor_swarm

# Build and install your linked packages.
sh develop.sh build
sh develop.sh install
