I'm using xacro's new ability to load a yaml file into a property in order to update a URDF with new calibration data.
The file in the example is local. Is there any way to hook this up to rospack so I can include this xacro file in another one? I tried an inner $( ) but it didn't work.
You apparently only need one set of ${} per property. So rather than trying to double up with
<xacro:property name="filename" value="$(find package)/file.yaml"/>
<xacro:property name="dictionary" value="${load_yaml(${filename})}"/>
or
<xacro:property name="dictionary" value="${load_yaml($(find package)/filename.yaml)}"/>
like I tried to do, use two different properties, like so:
<xacro:property name="filename" value="$(find package)/file.yaml"/>
<xacro:property name="dictionary" value="${load_yaml(filename)}"/>
The filename will be substituted already since it's already in curly brackets. You don't need two sets.
Thanks to [Robert Haschke] for this answer.
