Bash snippet to create and remove ROS workspaces

.bash_aliases

# ~/.bash_aliases
# ...

# Assuming you already have ROS installed...

# First create an empty file ~/.ros_workspaces using:
# `touch ~/.ros_workspaces`
# (I used this file to automatically source the devel/setup.bash
# script from all my ROS workspaces on startup)

alias dirros='cd <path>'
# path = path to the folder that will contain all your ROS workspaces.
# (I used to store all my ROS workspaces in ~/ros folder)

# Create and initialise ROS workspace
# Usage:
# `roscreate myworkspace`
roscreate() {
        dirros
        if [ -d `pwd`/$1 ];
        then
                echo "Workspace $1 already exists."
        else
                mkdir $1 && cd $1
                mkdir src && cd src
                catkin_init_workspace
                cd ..
                catkin_make
                echo "source `pwd`/devel/setup.bash" >> ~/.ros_workspaces
                source ./devel/setup.bash
        fi
}

# Delete ROS workspace
# Usage:
# `rospurge myworkspace`
rospurge() {
        dirros
        if [ -d ./$1 ];
        then
                rm -r ./$1
                grep -v "`pwd`/$1/devel/setup.bash" ~/.ros_workspaces > tmpfile
                cp -f ./tmpfile ~/.ros_workspaces
                rm ./tmpfile
                echo "Workspace $1 removed."

                echo "Workspace $1 does not exist."
