Defined in:

Overview

Validates the structural integrity of a TTC/OTC/dfont collection (TODO 74). Complements ValidateCommand, which runs profile-based checks against a single face. This command runs collection-level checks: face count, per-face glyph cap, optional cmap-union size.

Returns an integer exit code (0 = all checks passed, 1 = any check failed) suitable for use as the CLI's exit status.

The command is intentionally narrow: it does not subclass BaseCommand (which eagerly loads a single font at construction time) because the input here is a collection, not a single face. It owns its own loading via Fontisan::Collection::Reader.

    required face count, or nil to skip

  • max_glyphs (Integer) (defaults to: DEFAULT_MAX_GLYPHS) —

    per-face glyph cap (default 65,535)

  • expected_cmap_union (Integer, nil) (defaults to: nil) —

    minimum cmap-union size, or nil to skip
