Dependencies

The inventory CLI uses Python 3.12's standard library: ast for source structure, tokenize for Python encoding detection, xml.etree.ElementTree for UI/qrc structure, hashlib for exact original hashes, and argparse/json/pathlib for explicit local inputs and portable output. It has no Qt runtime dependencies. Port-state regeneration adds no packages. It projects existing manifest metadata and checks source hashes without accessing the private archive. State-dependent tests use pytest.skip, with clean_room_pending as their only relocation skip condition. Official AST, tokenize and ElementTree documentation were checked before implementation.

pytest supplies owned-fixture tests and committed-catalog acceptance checks; pytest-cov is optional coverage tooling. Ruff provides scoped lint and formatting. Use uv run --no-project --with pytest and uvx ruff to run them without adding dependencies to FontLab's embedded interpreter. Upstream dependency imports and requirements declarations are inventory evidence, not packages installed here.

The first four ports require FontLab's own PythonQt and existing QApplication. fontlab-fontlabapp supplies fontlabapp.widgets.OwnedWidget; the launcher imports that dependency only for launch, so catalog/help work outside the host. No PyQt/PySide, Qt.py or second Qt runtime is required. Standard-library importlib loads the four catalog-mapped port paths; pathlib resolves the exact UI resource. fontlab-remopy is optional on the external controller only, used by examples/remopy.py and tools/native_cleanroom.py to execute ordinary Python in an already configured FontLab. The acceptance driver requires Python 3.11 and adds no host dependencies. Its phases use the current local Remopy FontLab.run result contract and the existing Fontlabapp ownership implementation.

Consumer calls were checked against the current local fontlabapp/widgets.py and Remopy control.py/execution.py, and official PythonQt documentation, QUiLoader, QDialog open/modality and QApplication documentation. Native prerequisite receipts confirm FontLab's actual clicked callback and original Designer load/connections. Port interaction acceptance remains separate.

No additional FontLab dependency is installed. All implemented ports retain PythonQt and fontlab-fontlabapp ownership requirements. QSoundEffect, QtQml, QtQuick, QtSql and the standalone fbs/PyQt6 freezer are recorded host capability gaps.

Batch 4 adds no packages. Standard-library csv, pathlib, pickle, math and a local random.Random preserve the upstream data/animation behavior. Pickle is limited to string dictionaries in an owned temporary directory and denies global/class loading. Qt's QBuffer/QDataStream QVariant methods replace unsupported Python stream operators. API names were checked against the host's QtCore/QtGui/private stubs; PythonQt datatype documentation confirms QByteArray.data() and QVariant conversions. Exact overload and virtual callback behavior still requires the controller's native acceptance.

Re-evaluation 2026-10-15 (R046)

  • No pip packages are installed into FontLab for the examples. Ports use FontLab's PythonQt only.
  • examples/recipes/ import sibling workspace packages: fontlab-fontlabapp, fontlab-glyport (including its synthesized GlyphsApp/Foundation modules) and, from the external controller, fontlab-remopy. The native drivers put the real checkouts on FontLab's sys.path in a guarded call and restore it afterwards.
  • Development tools: pytest (uv run --no-project --with pytest), pytest-cov (optional) and ruff (uvx ruff). None of them run inside FontLab.
