Singularity: 3.0.0 singularity pull no long accepts --name, but this is not mentioned in the changelog

[mr-c]

Hello and congratulations on the new Singularity release!

Version of Singularity:

3.0.0

Expected behavior

Conventional command line invocations that worked in v2.[56].x continue to work in v3.0.0, except as documented at https://github.com/sylabs/singularity/blob/master/CHANGELOG.md

Example from the CWL reference runner, cwltool

['singularity', 'pull', '--force', '--name', 'kernsuite-prefactor.img', 'docker://kernsuite/prefactor']

(Singularity downloads the docker container and saves it as a Singularity image using the value of --name)

Actual behavior

--name is not listed on the v3.0.0 changelog

['singularity', 'pull', '--force', '--name', 'kernsuite-prefactor.img', 'docker://kernsuite/prefactor']
Error: unknown flag: --name
Usage:
singularity [global options...] pull [pull options...]

Steps to reproduce behavior

Install Singularity v3.0.0

singularity pull --force --name kernsuite-prefactor.img docker://kernsuite/prefactor

Hi @mr-c , thanks for pointing this out. The syntax to preform this action is now singularity pull <name> <uri>. In your example, singularity pull kernsuite-prefactor.img docker://kernsuite/prefactor will work as expected. Sorry for the confusion

[mr-c]

Can you accept the old syntax?

+1 for having --name option as alternative syntax as @mr-c is suggesting. Application invoking singularity tool programmatically are not aware of the underling version therefore cannot switch to the new syntax without breaking existing applications.

it works like a charm. Well done folks!
