Make -s|--schema take path or add new --schema-file option to point to schema.json file

[yarikoptic]

ATM the option seems to take only some hardcoded set of versions

  -s, --schema                    BIDS specification schema version to use for
                                  validation, e.g. "v1.6.0" (beta)
         [choices: "disable", "v1.6.0", "v1.7.0", "master"] [default: "disable"]

(note: current release is 1.9.0!).

That precludes to point to a specific schema.org e.g. produced while working on a BEP. Ref:

• Rework CONTRIBUTING:BEPs section for schema-driven approach #1828

Quick resolution would be appreciated to proceed with

• BIDS-2.0 bids-specification#1775

The schema validator shows:

❯ deno run --allow-read --allow-env https://deno.land/x/bids_validator/bids-validator.ts --help

  Usage:   bids-validator <dataset_directory>
  Version: alpha                             

[...]

    -s, --schema          <type>  - Specify a schema version to use for validation                          (Default: "latest")   

This appears to be an experimental addition to the legacy validator. Probably best just to remove it.

[yarikoptic]

But how to specify not by "version" but by the path to the schema???

[effigies]

deno run --allow-read --allow-env --allow-net https://deno.land/x/bids_validator/bids-validator.ts -s https://bids-specification.readthedocs.io/en/v1.9.0/schema.json /path/to/dataset

oh, will it work with file:// URLs? (happen you could check quickly... if not -- I will try later). Just need to wrap it all up into
https://github.com/bids-standard/bids-specification/pull/1775/files#diff-340dd8fa4a5cba6b30520d676d1831fd82628971874ea46396e3ace6c6ef0f03R111 but also then also into bep032 etc ... I feel like we need a github action to reuse here... Filed

• github action to run bids-validator on bids-examples #1931

WDYT @effigies ?

File URLs or a path to a local file should work.

[yarikoptic]

just for clarity -- https://github.com/bids-standard/bids-examples/blob/master/.github/workflows/validate_datasets.yml aren't using new validator yet?

[effigies]

Correct.

[effigies]

Resolved in #1932.

I wasn't able to get -s to work with file:// Is this a me problem/has anyone else had luck with it?

[effigies]

I have BIDS_SCHEMA=file://$HOME/Projects/bids/specification/src/schema.json bids-validator micr_SPIM in my history. I'm not sure if I've tried with -s or if things have stopped working since I last did that.
