Hi,<div><br></div><div>If we discuss roslaunch extension, one very important thing would be to add dependencies, i.e. launch prog X once Y is running...</div><div>I know this raises all kind of complicated issues especially when respawning but it would avoid developing the corresponding logic in each node.</div>

format?<br>
<br>
I would like to propose modifications to the &lt;launch&gt; tag by adding a<br>
&#39;name&#39; and &#39;description&#39; attributes or elements. Icon information might<br>
also be nice as well, but isn&#39;t really as important. These will help<br>
make it easier to figure out what your launch files do in a way that is<br>
machine readable for other applications.<br>
<br>
For example, one idea is to be able to double click on a launch file<br>
have it start without a terminal, then it could call libnotify with the<br>
name and description of the launch file that was started.<br>
<br>
This would provide helpful feedback to the user as some launch files<br>
take a while to actually start.<br>
<br>
One issue I see is that libnotify/dbus seem designed to work on the<br>
local machine and multi master will probably fail. One fix for this<br>
might be to have roslaunch broadcast the Name and Description of each<br>
launch file it starts on a topic. Another node could then bridge this<br>
topic to libnotify.<br>
<br>
tl;dr<br>
launch file as a desktop icon, click it, too long to start.<br>
What is the easiest way to fix?<br>
