"""Validate packages, or run the correction gate on proposals against a package.
|
|
|
|
Non-normative tooling.
|
|
Usage: python3 tools/validate.py PACKAGE [PACKAGE ...]
|
|
python3 tools/validate.py --correction PROPOSALS PACKAGE
|
|
A package is a folder, or a zipped package (`.sct.zip`), which is unpacked under the rules of spec/12 §12.2
|
|
before it is checked. Each is checked as spec/22 §22.2 describes, and each failure printed as
|
|
`package: where: rule: message`.
|
|
With --correction, PROPOSALS is a JSON file holding one proposed correction, or a JSON Lines file of several
|
|
applied in order. Each runs through the gate (spec/11 §11.4) against the package's current state, and the record
|
|
it would append to corrections.jsonl is printed, until one is refused. Nothing is written.
|
|
Exit status: 0 when everything is valid, 1 when something is refused, 2 for a usage error.
