Description:

jsonschemacli2 1.3.1

This is based on the frok from jsonschema-cli.
JsonSchema CLI
A thin wrapper over Python Jsonschema to allow validating shcemas easily using simple CLI commands.
Installing
pip install jsonschema-cli2
Security
The $ref resolving will automatically resolve to any path using basic $ref notation:
{"$ref": "my-custom.json#...."}

That means that when using this tool, an attacker may do the following:
{"$ref": "../../../../all-my-secrets.json"}

To make sure this doesn't happen:

When using this tool in a backend server, make sure the file access is scoped.
Don't run JSONSCHEMAS without sanitizing paths.
Treat all un-knwon user input as evil.

This has no actual current affect other than loading the contets of secrets into memory of the process.
But may lead to misfortune if not addressed.

Examples
# Returns no errors on stdout, no output needed on success (just exit code 0 is enough)
jsonschema-cli validate '{"properties": {"number": {"type": "integer"}}, "required": ["number"]}' '{"number": 123}'
# Has an error, "number" is now "123" instead of 123, an integer is expected.
jsonschema-cli validate '{"properties": {"number": {"type": "integer"}}, "required": ["number"]}' '{"number": "123"}'
> '123' is not of type 'integer'
>
> Failed validating 'type' in schema['properties']['number']:
> {'type': 'integer'}
>
> On instance['number']:
> '123'

Load YAML
The CLI command can read YAML and validate both schema and data written in YAML
# Returns no errors on stdout, no output needed on success (just exit code 0 is enough)
SCHEMA="
properties:
number:
type: integer
"
DATA="
number: 123
"
jsonschema-cli validate "$SCHEMA" "$DATA"
# Has an error, "number" is now "123" instead of 123, an integer is expected.
SCHEMA="
properties:
number:
type: integer
"
DATA="
number: \"123\"
"
jsonschema-cli validate "$SCHEMA" "$DATA"
> '123' is not of type 'integer'
>
> Failed validating 'type' in schema['properties']['number']:
> {'type': 'integer'}
>
> On instance['number']:
> '123'
