From 824194dc87bf5e86ef0aadb69e946a7b68a4a3d8 Mon Sep 17 00:00:00 2001 From: Ronald Tse Date: Sat, 27 Jun 2026 15:59:56 +0800 Subject: [PATCH 1/2] feat: Opal payload generator, boot file, and loader Under Opal, autoload declarations do not lazy-execute, so consumers (plurimath-js) need an explicit boot file that eager-requires every autoloaded entry point in dependency order. unitsml is unique among the moxml-dependent gems: it ships a large unitsdb YAML database that must be pre-serialized as a Ruby hash under Opal (no filesystem). This change adds the full Opal toolchain for unitsml: - lib/unitsml/opal.rb: boot file eager-requiring every autoloaded entry point. Requires upstream boot files (unitsdb/opal, mml/opal, omml/opal) and the payload file so Database.from_db can satisfy without a filesystem. - lib/unitsml/opal/payload_generator.rb: Unitsml::Opal::PayloadGenerator class that reads unitsdb-ruby YAML data on MRI and emits a Ruby source file defining Unitsml::Unitsdb::Database::DATABASE as a frozen hash. Invoked via rake unitsml:generate_opal_payload. - lib/unitsml/opal/database_payload.rb: AUTO-GENERATED output committed to the gem. Loaded by the boot file under Opal. - lib/unitsml/unitsdb/database.rb: adopts the loader mechanism from fix/opal-database-payload-loader (load_opal_payload, opal_payload, reset_opal_payload) so tests can inject small payloads and the committed DATABASE constant is found via const_defined?(:DATABASE, false). Supersedes PR #65. - lib/unitsml/unitsdb.rb, lib/unitsml/model.rb and the four nested model parent files: convert require_relative and __dir__-interpolated autoloads to plain load-path-relative autoload declarations, per the global rule. Removes a dangling autoload (Unitsml::Model:: Namespace) whose target file never existed; MRI never tripped on it because nothing referenced the constant, but Opal eager-loads every autoload and would have crashed. - Rakefile: adds the unitsml:generate_opal_payload task. - Gemfile: adds nokogiri and opal so the boot-file spec can compile the boot file end-to-end via Opal::Builder with native deps stubbed. - .rubocop.yml: excludes the generated payload file from lint. - spec/unitsml/opal_boot_spec.rb: verifies the boot file structure and that Opal::Builder compiles it end-to-end with stubs. - spec/unitsml/payload_sync_spec.rb: verifies the committed payload matches what the generator produces from the current unitsdb gem and that it round-trips through from_hash. - spec/unitsml/opal/payload_generator_spec.rb: verifies the generator produces evaluable Ruby that reproduces the source database. - spec/unitsml/unitsdb/database_spec.rb: extends coverage to the new loader mechanism (load_opal_payload, DATABASE fallback). -

The committed payload file is generated on whichever Ruby the maintainer runs, but the payload_sync_spec runs on every supported Ruby in CI -- so a 3.3 maintainer committing the file would fail CI on 3.4, and vice versa. Replace Hash#inspect with a recursive serializer that produces byte-identical output across Rubies. Strings still use inspect (which is stable for UTF-8 clean data). --- lib/unitsml/opal/database_payload.rb | 2 +- lib/unitsml/opal/payload_generator.rb | 23 ++++++++++++++++++++++- 2 files changed, 23 insertions(+), 2 deletions(-) diff --git a/lib/unitsml/opal/database_payload.rb b/lib/unitsml/opal/database_payload.rb index 5da4d73..1e16f7f 100644 --- a/lib/unitsml/opal/database_payload.rb +++ b/lib/unitsml/opal/database_payload.rb @@ -4,4 +4,4 @@ # Do not edit by hand.
