Overview

Pre-flight validation for a universal-set build. Runs the three checks TODO 31 specifies:

  1. Source config loads cleanly. SourceConfig.new(path:) returns a map without raising, and the file exists.
  2. All fonts present. Every source in the map resolves to a file on disk (kind=path) or via fontist's index (kind=fontist, install: false). Missing fonts are listed.
  3. Coverage assertion runs. TODO 29's CoverageAssertion walks every assigned codepoint; gaps are surfaced but do not abort (expected for residual curation cases).

The check raises UniversalSetPreBuildError when missing_fonts is non-empty or the config fails to load. The CLI catches this and renders the failing checks; the build never starts with known-bad inputs.

Constructor Details

#initialize(source_config_path:, database:, cmaps: nil, font_locator: RealFonts::FontLocator.new) ⇒ PreBuildCheck

Returns a new instance of PreBuildCheck.

Parameters:

  • source_config_path (String, Pathname)
  • database (Ucode::Database) —

    open database for the target Unicode version. Used by CoverageAssertion.

  • cmaps (#covers?) (defaults to: nil) —

    defaults to RealFonts::CmapCache. Injectable for testing (e.g. StaticCmaps).

  • font_locator (#locate) (defaults to: RealFonts::FontLocator.new) —

    defaults to a fresh FontLocator. Injectable for testing.
