Will cloud-volume support the new Neuroglancer $PROTOCOL://$BUCKET/$DATASET/$LAYER|$FORMAT:?

[chourroutm]

Neuroglancer has introduced $PROTOCOL://$BUCKET/$DATASET/$LAYER|$FORMAT: as an alternative to $FORMAT://$PROTOCOL://$BUCKET/$DATASET/$LAYER. Is it something that will be supported in the near future by cloud-volume?

I just added some support to cloudfiles for dealing with "|neuroglancer-precomputed:" specifically, but it'll need a bit more work.

Okay, thanks!

As a workaround, would this work?

import re
import cloudvolume

def _legacy_source_url(source_url):
    match = re.match(r'^(.*)\|(.*)\:$', source_url)
    if match:
        protocol_url = match.group(1)
        pipe_format = match.group(2)
        if pipe_format == "neuroglancer-precomputed":
            pipe_format = "precomputed"
        return f"{pipe_format}://{protocol_url}"
    return source_url

vol = cloudvolume.CloudVolume(_legacy_source_url(source.url), parallel=True, progress=True, use_https=True)
