Implement comprehensive weather parsing capabilities following Clean
Architecture principles with composite parser pattern for routing between
aviation and weather messages.
## Features Added
- Weather report parsing (METAR, SPECI, TAF)
- Composite parser pattern for message routing
- Lenient parsing with warnings for unrecognized tokens
- Support for PROB and RMK sections in TAF
- Rich domain modeling with typed weather elements
## Architecture
**Domain Layer** (internal/domain/weather/):
- WeatherMessage interface with Metar and Taf implementations
- Weather elements: Wind, Visibility, Cloud, Temperature, Altimeter, Phenomenon
- Domain errors: ErrInvalidFormat, ErrMissingStation, ErrMissingTime
**Port Layer** (internal/port/weather_parser.go):
- WeatherParser interface with CanParse and Parse methods
**Adapter Layer** (internal/adapter/parser/weather/):
- WeatherParserImpl with classification and parsing logic
- Comprehensive regex patterns for weather elements
- METAR/SPECI parser with element extraction
- TAF parser with period handling (FM, TEMPO, BECMG, PROB)
- Helper functions for time parsing and unit conversions
**Composite Parser** (internal/adapter/parser/composite.go):
- Routes weather reports to weather parser
- Falls back to aviation parser for telegrams
- Converts WeatherMessage to ParsedTelegram format
## Integration
- Updated ProvideParser to create composite parser with weather parser
- Added weather parser to Wire DI configuration
- Updated processor_bench_test.go for weather parser integration
- Documentation added in docs/weather-parser.md
## Testing
- 29 comprehensive tests for weather parsing (all passing)
- Tests for classification, METAR, SPECI, TAF, and composite routing
- Benchmark compatibility maintained
## Fixes Applied
- TAF PROB parsing: Include PROB/RMK in special section detection
- Composite test: Updated to use properly formatted AFTN telegram
- Linter issues: Switch statement refactor, removed unused patterns
- Ineffective break statement fixed in TAF parser
## Coverage
~1,743 lines of new code with:
- Complete METAR/SPECI parsing
- TAF parsing with period support
- Lenient error handling with warnings
- Unit conversions and time utilities

The code changes introduce a new `Index` field in the `FlightSchedule` struct and update the parsers in `aviation_parser.go` and `schedule_parser.go` to handle this field. This addition allows for the extraction and parsing of the `Index` value from flight schedule messages. The changes improve the functionality and accuracy of the code when working with flight schedules.
The code changes in `pln.go` introduce a new `FlightSchedule` struct and validation logic. This struct represents a flight schedule and includes various fields such as date, category, flight number, aircraft registration, passenger configuration, ILS category, departure airport, departure time, schedule info, arrival time, arrival airport, comments, and reference. The `Validate` method ensures that the required fields are populated and returns an error if any field is missing. This addition improves the overall functionality and data integrity of the code.
The code changes in `aviation_parser.go` and `aviation_parser_test.go` enhance the CNL message parsing logic in the `BodyParser` module. This ensures accurate extraction of data from CNL messages, including the category, aircraft ID, departure airport, and destination airport. The improvements improve the overall functionality and accuracy of the code.
The code changes in `aviation_parser.go` and `aviation_parser_test.go` add CNL message parsing logic to the `BodyParser` module. This allows for the correct extraction and parsing of CNL messages, including the category, aircraft ID, departure airport, and destination airport. This enhancement improves the overall functionality and accuracy of the code.
The code changes in `pattern_test.go` update the ARR body parsing logic. The message body parsing now correctly handles ARR bodies with a different pattern format. This ensures accurate extraction of data based on patterns and improves the overall functionality of the code.
The code changes in config.dev.toml and sub.go update the configuration and message handling for integrating with Hasura. The config.dev.toml file now includes a new section for Hasura configuration, specifying the endpoint and secret. In sub.go, the UUID field is set to the UUID of the received message, ensuring proper tracking of parsed messages. This refactor enables seamless integration with Hasura and improves the functionality of the code.
The code changes in fpl.go update the Flight Plan (FPL) structure fields. The FlightNumber, AircraftID, SSRModeAndCode, CruisingSpeedAndLevel, DepartureAirport, DepartureTime, Route, DestinationAndTotalTime, AlternateAirport, EstimatedArrivalTime, SELCALCode, and EstimatedElapsedTime fields are modified to reflect the new values. This refactor ensures accurate representation of the FPL data and improves the overall functionality of the code.
The code changes remove the unused fields in the `aviation.go` file, specifically the `CallSign`, `FlightPlanID`, `Route`, `Altitude`, `Speed`, `Position`, `EmergencyIndicator`, `ReportType`, `SupplementaryInfo`, `FilingTime`, `OriginatorIndicator`, `ServiceInformation`, and `NavigationAidInfo` fields. These fields were no longer needed and were causing unnecessary clutter in the codebase. This refactor improves code cleanliness and maintainability.
The code changes rename the "Text" field in the AFTN struct to "Body" to improve clarity and consistency. This change aligns with the naming convention used in other parts of the codebase and enhances code readability.
The code changes remove the unused `SurveillanceEquipment` field in the `FPL` struct and the `TelegramCategory` field in the `DEP` struct. These fields are no longer needed and can be safely removed. This commit improves code cleanliness and reduces unnecessary complexity.
The code changes in `config.go` remove the commented code for printing a validation message and update the fields of the `FPL` struct in `fpl_test.go`. The commented code is no longer needed and can be safely removed. The updated fields in the `FPL` struct reflect the latest requirements and improve the accuracy of the test cases. This commit enhances code readability and maintainability.
