Extract path of source without frame number

I seem to feel like this already exists...

 

I'm trying to determine the path of a source without baked in frame numbers.  When users use shell expansion, frame numbers are explicitly baked it; and I imagine there's many other ways of specifying frames that will result in various formats.

 

So before I try to cover them all on my own, is there any sort of mu/python command that can extract the name of a path sans explicit frame numbers for use in accompanying scripts?

    Hi Michael,

    Are you trying to take something like:

    image.1.exr, image.2.exr, ... image.N.exr

    and get back:

    image.1-N@.exr

    Is that what you are trying to do? If not can you please give me a before and after kind of thing.

    Thanks,
    Jon

    Yeah; that's the sort of thing; only the expansion is happening from the shell.

     

    An artist types rv *.exr in a directory; which is essentially doing rv image.1.exr image.2.exr, image.N.exr...

    Hi Michael,

    I found this in the Help -> Mu Commands API Browser...

    Path: commands.contractSequences

    contractSequences (string[]; 
                   string[] files)

    Description

    Given an array of file names, the function will attempt to contract them into image sequence notation. For example, the files:

     foo.0001.tif
 foo.0002.tif
 foo.0003.tif
 foo.0004.tif

    would result in a single sequence named foo.#.tif. See the rv user's manual for information about sequence notation.

    Please let me know if that works.

    Thanks,
    Jon

    Hi Jon and Michael,

    rv.commands.sequenceOfFile("image.0001.exr")
    also tries to attempt to return "image.1-110#.exr"

     

    cheers
