# looking for the package in yaml file

Hey,

Is there a way to look through yaml file a path to a file?

So basically I'd like to do something like this.

I have launch file:

<launch>
<node pkg="123" type="1234" name="1234">
<param name = "fileOut"       value = "output.pcd" />
<param name = "folder_path"   value = "$(find pcjoiner)/point_clouds/" /> </node> </launch>  and I'd like to $(find pcjoiner)/point_clouds/ place in yaml file. So to have it very flexible? Maybe it doesn't make sense? What do you think?

Edit: So in my case in yaml file should I have:

parameter1:$(find package)/folder/folder2/folder3  or parameter1: package parameter2: /folder/folder2/folder3  ? edit retag close merge delete ## 1 Answer Sort by » oldest newest most voted This should be supported by roslaunch if you use rosparam with the subst_value set to true.

Yes, according to the docs I linked, that should work.
