From 8246b93c9e16879ae46e6a5123765c8358d793ca Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 15:12:52 +0000 Subject: [PATCH 1/5] Add comprehensive mypy type annotations with strict configuration This commit adds complete type annotations to all Python files in the prance codebase and configures mypy with strict type checking settings. Key changes: - Configure mypy in pyproject.toml with strict settings: - disallow_untyped_defs=true - disallow_untyped_calls=true - disallow_incomplete_defs=true - warn_return_any=true - Other strict type checking options - Add type annotations to all modules: - prance/util/exceptions.py: Type-annotated raise_from function - prance/util/iterators.py: Added JsonValue and PathElement type aliases - prance/util/path.py: Complete type annotations for path operations - prance/util/__init__.py: Typed utility functions - prance/util/fs.py: File system operation types - prance/util/formats.py: Format parsing and serialization types - prance/util/url.py: URL handling with proper ParseResult types - prance/util/resolver.py: Reference resolution with full typing - prance/util/translator.py: Reference translation types - prance/mixins.py: Mixin classes with proper typing - prance/__init__.py: Core parser classes fully typed - prance/convert.py: Conversion functions typed - prance/cli.py: CLI interface types - Type design principles: - Used specific types instead of Any wherever possible - Defined JsonValue type alias for JSON-like structures - Properly handled optional dependencies with type: ignore comments - Added type narrowing with isinstance checks - Used Union, Optional, Sequence, Mapping appropriately - Mypy configuration: - Added CLI module override to allow untyped decorators from click - All files now pass mypy strict checking All type checking now passes: mypy prance/ returns success. --- prance/__init__.py | 92 ++++++++++++++++++++----------------- prance/cli.py | 38 ++++++++-------- prance/convert.py | 31 +++++++++---- prance/mixins.py | 17 ++++--- prance/util/__init__.py | 21 +++++---- prance/util/exceptions.py | 6 ++- prance/util/formats.py | 50 +++++++++++---------- prance/util/fs.py | 22 ++++----- prance/util/iterators.py | 21 +++++++-- prance/util/path.py | 51 ++++++++++++--------- prance/util/resolver.py | 88 ++++++++++++++++++++++-------------- prance/util/translator.py | 71 ++++++++++++++++++----------- prance/util/url.py | 95 ++++++++++++++++++++++++--------------- pyproject.toml | 20 +++++++++ 14 files changed, 389 insertions(+), 234 deletions(-) diff --git a/prance/__init__.py b/prance/__init__.py index 63222fc..75f0e71 100644 --- a/prance/__init__.py +++ b/prance/__init__.py @@ -7,16 +7,21 @@ ResolvingParser that additionally resolves any $ref references.
