Overview

Produces one Models::Audit::BlockSummary per touched Unicode block for a font's cmap codepoint set, compared against a CoverageReference.

Pure transformation: takes a reference + the font's codepoint list, returns BlockSummary. No I/O beyond the reference's lookups, no mutation of inputs.

The "assigned" set for a block comes from reference.entries_for_block(name). For a UcdOnlyReference that's every codepoint in the block's UCD ranges. For a UniversalSetReference it's every codepoint the universal glyph set built a glyph for in that block — each entry carries tier + source provenance that gets attached to the missing-codepoint list (TODO 25).

Constructor Details

#initialize(reference) ⇒ BlockAggregator

Returns a new instance of BlockAggregator.

Parameters:

  • reference (CoverageReference, Ucode::Database, nil) —

    pluggable baseline. For backwards compatibility a raw Ucode::Database is still accepted and wrapped in a UcdOnlyReference at construction time. When nil, #call returns an empty array.
