Bug report

Expected behavior and actual behavior

When staging an input file in a subdirectory with input: path x, stageAs: 'my-dir/*', then x.name gives my-dir/filename instead of just filename.

Steps to reproduce the problem

process my_proc {
    input: path x, stageAs: 'my-dir/*'
    script:
    print(x.name)
    """
    """
}

workflow {
    Channel.fromPath('my-file.txt')
    | my_proc
}

It looks like TaskPath just has a slightly different API from Path. The getName() method returns the entire filename. You can get the base name with x.fileName.name.

I will make a note to document TaskPath in the Nextflow docs.

[julibeg]

I see, thanks for clarifying!

[julibeg]

is there a difference between x.fileName.name and x.alias?

[bentsherman]

Yes, x.alias is equivalent to x.name so it's not what you want.
