HOM to expand/condense point lists "8 10-13 2" <-> &#3

[cruiserandmax]

Are there any convenience functions in the python HOM to expand/condense "group" type lists of geometry? Or do I have to write my own python functions to handle this?

 

For example I want to change:

 

1 5 8-11 13  into  1 5 8 9 10 11 13

 

or the other way around.

 

Also I'd like to be able to clean up:

 

1-10 5-12 20  into  1-12 20

 

Before I deal with it myself I figured there might be something in HOM that helps since it's such a standard way of listing geometry in Houdini.

 

Thanks!

If you have the actual geometry, then for expanding, you can make use of hou.Geometry's globPoints(), globPrims(), etc. that returns you back a tuple. So untested code would be something like:

" ".join([str(pt.number()) for pt in geo.globPoints("1 5 8-11 13")])

I'm not sure if there's an easy one liner for condensing though.

Thanks, that is an elegant combination of python and globPoints()!
