Code Review

This pull request introduces the functionality to export trips.trip_id, which is a valuable addition. The implementation is well-executed, with new classes MTripId and MTripIds that are consistent with existing patterns for handling IDs. The integration into the data loading, generation, and dumping processes is clean. I appreciate the refactoring done in MSchedule, MFrequency, and MServiceDate to centralize logic into MServiceIds.convert() and MTripIds.convert(), which improves code maintainability. The replacement of the hardcoded EXPORT_TRIP_ID flag with a feature flag is also a good improvement. I have one minor suggestion to improve consistency in naming. Overall, this is a great contribution.

Pull request overview

This PR adds support for exporting trips.trip_id as integers similar to the existing service ID integer export functionality. The changes enable tracking and converting trip IDs between string and integer representations, controlled by a feature flag.

Key changes:

• Introduces MTripId data class and MTripIds object for managing trip ID mappings
• Adds convert() methods to both MTripIds and MServiceIds for conditional formatting
• Updates schedule file generation to use the new trip ID conversion system

Code Review

This pull request successfully implements the export of trips.trip_id, controlled by a new feature flag. The introduction of MTripId and MTripIds is consistent with the existing architecture for handling IDs.

Beyond the main feature, this PR includes valuable refactoring that improves code quality and maintainability:

• Code Consolidation: The file reading logic in MReader.kt has been nicely refactored into a generic readFile function, reducing code duplication. Similarly, schedule serialization in MSchedule.kt is now handled by a single toFile method.
• Bug Fixes & Clarity: A bug in GSpec.java related to service ID cleanup has been fixed, and variable names have been improved for clarity (e.g., mTripsList to mDirectionsList).
• Enhanced Logging: The addition of prefixes to log messages throughout DefaultAgencyTools.java will make debugging easier.

I've provided a couple of suggestions to further improve code clarity and fix a minor logging issue. Overall, this is a solid contribution.
