From a39c7943daa071b9ef7d524d90b9376e73c209c9 Mon Sep 17 00:00:00 2001 From: Ibrahim Hadzic Date: Sun, 16 Nov 2025 17:43:49 -0500 Subject: [PATCH 1/9] Remove CLI module in favor of manual parsing pattern MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove the built-in CLI parsing utilities (`Config.from_cli()`, `parse_override()`, `parse_overrides()`) to simplify the library and encourage users to handle their own argument parsing with standard libraries like argparse, click, typer, or fire. **Why:** - Reduces library complexity and maintenance burden - Users have full control over CLI behavior and flags - Works better with diverse CLI frameworks - The recommended pattern is simple: just 3 lines of code for basic CLI override parsing **Migration path:** ```python # Old way config = Config.from_cli("config.yaml", sys.argv[1:]) # New way (3 lines) config = Config() config.update("config.yaml") for arg in sys.argv[1:]: if "=" in arg: key, value = arg.split("=", 1) try: value = ast.literal_eval(value) except (ValueError, SyntaxError): pass config.set(key, value) ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/sparkwheel/cli.py | 159 -------------------- tests/test_cli.py | 338 ------------------------------------------ 2 files changed, 497 deletions(-) delete mode 100644 src/sparkwheel/cli.py delete mode 100644 tests/test_cli.py diff --git a/src/sparkwheel/cli.py b/src/sparkwheel/cli.py deleted file mode 100644 index e612041..0000000 --- a/src/sparkwheel/cli.py +++ /dev/null @@ -1,159 +0,0 @@ -""" -CLI utilities for Sparkwheel configuration overrides. - -This module provides utilities for parsing command-line configuration overrides -in the format "key::path=value".

type coercion system for schema validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce automatic type coercion to convert compatible types during validation, making configs more flexible and user-friendly. **Features:** - String to numeric conversion (`"123"` → `123`, `"3.14"` → `3.14`) - Numeric type conversion (`1` → `1.0` for float fields) - String to bool parsing (`"true"`, `"yes"`, `"1"` → `True`) - List/tuple interconversion - Dict to dataclass conversion (nested structures) - Preserves None values and handles Optional types correctly **Example:** ```python @dataclass class Config: port: int rate: float config = Config() config.update({"port": "8080", "rate": "0.5"}) # Strings coerced! config.validate(Config) # ✓ Works! port=8080, rate=0.5 ``` **Implementation:** - `coerce_value()`: Core coercion logic with recursive support - Smart type detection and conversion with fallback to original value - Integration with `_validate_field()` in schema.py 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/sparkwheel/coercion.py | 140 ++++++++++++++++++ tests/test_coercion.py |

4d06ee8c3da9a72a608e3c4b1800f646fb34d351 Mon Sep 17 00:00:00 2001 From: Ibrahim Hadzic Date: Sun, 16 Nov 2025 17:45:38 -0500 Subject: [PATCH 3/9] Enhance config API with freeze/unfreeze and MISSING support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add advanced configuration features for better control and partial config support. **New Features:** 1. **Frozen Configs** - Prevent mutations after initialization: ```python config.freeze() # Lock config config.set("key", "value") # Raises FrozenConfigError config.unfreeze() # Allow mutations again ``` 2. **MISSING Sentinel** - Support partial configs with required-but-not-yet-set values: ```python config = Config(allow_missing=True) config.update({"api_key": MISSING}) # Placeholder for later config.set("api_key", os.getenv("API_KEY")) # Fill in config.validate(schema) # Ensure complete (allow_missing=False by default) ``` 3. **Continuous Validation** - Validate on every mutation when schema provided: ```python config = Config(schema=MySchema) # Enable continuous validation config.update(data) # Validates immediately! config.set("port", "invalid") # Raises ValidationError ``` **API Changes:** - Add `freeze()`, `unfreeze()`, `is_frozen()` methods - Add `MISSING` sentinel constant - Add `allow_missing` parameter to `Config()` and `validate()` - Integrate type coercion into validation pipeline - Enhanced error messages with field paths **Tests:** - Comprehensive test coverage for freeze/unfreeze behavior - MISSING sentinel edge cases - Continuous validation scenarios - Updated existing tests for new API patterns 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/sparkwheel/__init__.py | 11 +- src/sparkwheel/config.py | 401

4/9] Comprehensive documentation updates for v0.0.5 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Update all documentation to reflect the new API design, removed CLI module, and new features (type coercion, freeze/unfreeze, MISSING sentinel). **Major Changes:** 1. **Installation Guide** (`installation.md`): - Simplified just installation instructions (use package managers) - Removed optional dependencies section (minimal deps by design) - Cleaner setup instructions 2. **Quickstart Guide** (`quickstart.md`): - Update to new API: `Config()` + `.update()` pattern (no more `.load()`) - Show manual CLI override parsing (3-line pattern with ast.literal_eval) - Method chaining examples for cleaner code 3. **CLI Overrides** (`cli.md` - major rewrite): - Remove `Config.from_cli()`, `parse_override()` references - Show auto-detection pattern: `.update()` handles both files and overrides - Examples for argparse, Click, Typer, Fire - Manual override parsing with `parse_overrides()` for advanced use - Simplified mental model: just loop over args! 4. **Core User Guides**: - `basics.md`: Update all examples to `Config().update()` pattern - `operators.md`: Add composition decision flow diagram - `advanced.md`: Add frozen configs and MISSING sentinel sections - `schema-validation.md`: Document continuous validation and type coercion - `references.md`: Update API references 5. **Index Page** (`index.md`): - Update feature descriptions (continuous validation) - Modernize all code examples - Show new patterns throughout 6. **Examples Cleanup**: - Delete outdated examples: `simple.md`, `deep-learning.md`, `custom-classes.md` - Add new `quick-reference.md` with concise API overview 7. **MkDocs Config** (`mkdocs.yml`): - Remove examples section from navigation - Add quick-reference to user guide - Update structure for clearer organization **Documentation Philosophy:** - Show the simplest pattern first (Config().update()) - Encourage users to use their preferred CLI library - Emphasize composition-by-default with explicit operators - Highlight continuous validation benefits 🤖 Generated with [Claude

Fix YAML syntax in check_pull_request_title.yml - Remove problematic types parameter (not needed with custom subjectPattern) Type Checking Fixes (66 errors resolved): - Keep strict mypy flags enabled (disallow_any_generics, warn_unreachable) - Add explicit type parameters throughout (dict[str, Any], list[Any], set[Any]) - Add type annotations to helper functions (_is_union_type, etc.) - Fix PathLike type parameter (Union[str, os.PathLike[str]]) - Add proper type hints to levenshtein_distance and ensure_tuple - Add type assertions for dataclass field types - Handle false positive unreachable warnings with targeted type ignores Files modified: - schema.py, coercion.py: Type annotations and assertions - config.py, loader.py, items.py: Dict/list/set type parameters - preprocessor.py, operators.py, resolver.py: Type parameters - utils/types.py, utils/misc.py, utils/module.py: Type fixes -
