This commit adds support for proper float32 (f32) and float64 (f64) precision handling in CEL expressions and serialization: Changes: - Added new `float()` conversion function that applies f32 precision and range rules, converting values through f32 to properly handle subnormal floats, rounding, and range overflow to infinity - Enhanced `double()` function to properly parse special string values like "NaN", "inf", "-inf", and "infinity" - Updated serialize_f32 to preserve f32 semantics when converting to f64 for Value::Float storage - Registered the new `float()` function in the default Context The float() function handles: - Float32 precision: Values are converted through f32, applying appropriate precision limits - Subnormal floats: Preserved or rounded according to f32 rules - Range overflow: Out-of-range values convert to +/-infinity - Special values: NaN and infinity are properly handled Testing: - Added comprehensive tests for both float() and double() functions - Verified special value handling (NaN, inf, -inf) - All existing tests continue to pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
This commit addresses 4 conformance test failures by implementing proper validation for: 1. **Undefined field access**: Enhanced member() function in objects.rs to consistently return NoSuchKey error when accessing fields on non-map types or when accessing undefined fields on maps. 2. **Type conversion range validation**: Added comprehensive range checking in the int() and uint() conversion functions in functions.rs: - Check for NaN and infinity values before conversion - Use trunc() to properly handle floating point edge cases - Validate that truncated values are within target type bounds - Ensure proper error messages for overflow conditions 3. **Single scalar type mismatches**: The member() function now properly validates that field access only succeeds on Map types, returning NoSuchKey for scalar types (Int, String, etc.) 4. **Repeated field access validation**: The existing index operator validation already properly handles invalid access patterns on lists and maps with appropriate error messages. Changes: - cel/src/functions.rs: Enhanced int() and uint() with strict range checks - cel/src/objects.rs: Refactored member() for clearer error handling These changes ensure that operations raise validation errors instead of silently succeeding or producing incorrect results. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
- Add EnumType struct to represent enum types with min/max value ranges - Implement convert_int_to_enum function that validates integer values are within the enum's valid range before conversion - Add comprehensive tests for: - Valid enum conversions within range - Out-of-range conversions (too big) - Out-of-range conversions (too negative) - Negative range enum types - Export EnumType from the public API This implementation ensures that when integers are converted to enum types, the values are validated against the enum's defined min/max range. This will enable conformance tests like convert_int_too_big and convert_int_too_neg to pass once the conformance test suite is added. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
Fixed 6 failing tests related to timestamp operations by implementing proper timezone handling for getDate, getDayOfMonth, getHours, and getMinutes methods. Changes: - Added optional timezone parameter support to timestamp methods - When no timezone is provided, methods now return UTC values - When a timezone string is provided (e.g., "+05:30", "-08:00", "UTC"), methods convert to that timezone before extracting values - Added helper functions parse_timezone() and parse_fixed_offset() to handle timezone string parsing - Added comprehensive tests for timezone parameter functionality The methods now correctly handle: - getDate() - returns 1-indexed day of month in specified timezone - getDayOfMonth() - returns 0-indexed day of month in specified timezone - getHours() - returns hour in specified timezone - getMinutes() - returns minute in specified timezone All tests now pass including new timezone parameter tests. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
This commit implements comprehensive support for protobuf extension fields in CEL, addressing both package-scoped and message-scoped extensions. Changes: - Added ExtensionRegistry and ExtensionDescriptor to manage extension metadata - Extended SelectExpr AST node with is_extension flag for extension syntax - Integrated extension registry into Context (Root context only) - Modified field access logic in objects.rs to fall back to extension lookup - Added extension support for both dot notation and bracket indexing - Implemented extension field resolution for Map values with @type metadata Extension field access now works via: 1. Map indexing: msg['pkg.extension_field'] 2. Select expressions: msg.extension_field (when extension is registered) The implementation allows: - Registration of extension descriptors with full metadata - Setting and retrieving extension values per message type - Automatic fallback to extension lookup when regular fields don't exist - Support for both package-scoped and message-scoped extensions This feature enables proper conformance with CEL protobuf extension specifications for testing and production use cases. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
- Add explicit loop condition evaluation before each iteration - Ensure errors in loop_step propagate immediately via ? operator - Add comments clarifying error propagation behavior - This fixes the list_elem_error_shortcircuit test by ensuring that errors (like division by zero) in list comprehension macros stop evaluation immediately instead of continuing to other elements 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

This commit merges the conformance test harness infrastructure from the conformance branch into master. The harness provides: - Complete conformance test runner for CEL specification tests - Support for textproto test file parsing - Value conversion between CEL and protobuf representations - Binary executable for running conformance tests - Integration with cel-spec submodule The conformance tests validate that cel-rust correctly implements the CEL specification by running official test cases from the google/cel-spec repository. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

This commit adds comprehensive tests for two conformance test scenarios: 1. **list_elem_type_exhaustive**: Tests type checking in list comprehensions with heterogeneous types. The test verifies that when applying the all() macro to a list containing mixed types (e.g., [1, 'foo', 3]), proper error messages are generated when operations are performed on incompatible types. 2. **presence_test_with_ternary** (4 variants): Tests has() function support in ternary conditional expressions across different positions: - Variant 1: has() as the condition (present case) - Variant 2: has() as the condition (absent case) - Variant 3: has() in the true branch - Variant 4: has() in the false branch These tests verify that: - Type mismatches in macro-generated comprehensions produce clear UnsupportedBinaryOperator errors with full diagnostic information - The has() macro is correctly expanded regardless of its position in ternary expressions - Error handling provides meaningful messages for debugging All existing tests continue to pass (85 tests in cel package). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
The conformance package was attempting to use a 'proto' feature from the cel crate that doesn't exist, causing dependency resolution to fail. Removed the non-existent 'proto' feature while keeping the valid 'json' feature. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

This commit fixes the broken build when running 'cargo test --package conformance'. The conformance tests were failing to compile due to missing dependencies: 1. Added Struct type to cel::objects: - New public Struct type with type_name and fields - Added Struct variant to Value enum - Implemented PartialEq and PartialOrd for Struct - Updated ValueType enum and related implementations 2. Added proto_compare module from conformance branch: - Provides protobuf wire format parsing utilities - Supports semantic comparison of protobuf Any values 3. Enhanced Context type with container support: - Added container field to both Root and Child variants - Added with_container() method for setting message container - Updated all Context constructors 4. Fixed cel-spec submodule access in worktree by creating symlink The build now completes successfully with cargo test --package conformance. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
Fix build broken: Add missing Struct type and proto_compare module
This commit implements full support for list comprehension syntax in the CEL parser
to resolve 79 failing conformance tests.
Changes:
- Updated ANTLR grammar (CEL.g4) to support list comprehension syntax: [result | var in range && filter]
- Added PIPE token ('|') to the lexer
- Regenerated parser from updated grammar using ANTLR4
- Implemented visit_ListComprehension() to transform comprehension syntax into Comprehension AST nodes
- Updated parser tests to expect correct error messages for pipe token
The implementation transforms list comprehensions into the existing Comprehension expression type,
following the same pattern as the map() and filter() macros. List comprehensions now support:
- Basic transformation: [x * 2 | x in [1, 2, 3]]
- Filtering with &&: [x | x in list && x > 2]
- Map iteration with optional second variable
- Empty list handling
