Overview

Produces one Models::Audit::BlockSummary per touched Unicode block for a font’s cmap codepoint set, compared against a ucode UCD baseline.

Pure transformation: takes the resolved baseline Database + the font’s codepoint list, returns BlockSummary[]. No I/O beyond the database lookups, no mutation of inputs.

The “assigned” set for a block is derived from the Database’s ranges-with-that-name. The Database stores coalesced runs of consecutive assigned codepoints grouped by block name, so the union of those ranges IS the assigned set for that block.

Constructor Details

#initialize(database) ⇒ BlockAggregator

Returns a new instance of BlockAggregator.

Parameters:

  • database (Ucode::Database, nil) —

    resolved baseline. When nil, #call returns an empty array — caller should treat that as “no UCD baseline available” and surface a warning.
