jsonschema_diff.core.tools.context¶

Attributes¶

`RULE_KEY`
`CONTEXT_RULES_TYPE`
`PAIR_CONTEXT_RULES_TYPE`

Classes¶

RenderContextHandler

Expand context comparators based on pair- and directed-dependency rules.

Module Contents¶

type RULE_KEY = str | Type['Compare'][source]¶

type CONTEXT_RULES_TYPE = Mapping[RULE_KEY, Sequence[RULE_KEY]][source]¶

type PAIR_CONTEXT_RULES_TYPE = Sequence[Sequence[RULE_KEY]][source]¶

class RenderContextHandler[source]¶

Expand context comparators based on pair- and directed-dependency rules.

static resolve( *, pair_context_rules: PAIR_CONTEXT_RULES_TYPE, context_rules: CONTEXT_RULES_TYPE, for_render: Mapping[str, jsonschema_diff.core.parameter_base.Compare], not_for_render: Mapping[str, jsonschema_diff.core.parameter_base.Compare], ) → Dict[str, jsonschema_diff.core.parameter_base.Compare][source]¶

Build the final ordered context for rendering.

Parameters:

pair_context_rules (Sequence[Sequence[RULE_KEY]]) – Undirected groups: if one member is rendered, pull the rest (order preserved).
context_rules (Mapping[RULE_KEY, Sequence[RULE_KEY]]) – Directed dependencies: source → [targets...].
for_render (Mapping[str, Compare]) – Initial items, order defines primary screen order.
not_for_render (Mapping[str, Compare]) – Optional items that may be added by the rules.

Returns:

dict – Ordered {name -> Compare} ready for UI.
Algorithm (high-level)
———————-
* Walk through *for_render keys.*
* While iterating, append new candidates to the tail of the scan list.
* A candidate is added once when first matched by any rule.
