Preprocessing Implementation Summary

Implementation Complete ✓

The preprocessing functionality for BOM conditions has been successfully implemented according to the plan.

Files Created

1. M05_PreProcessor.bas

Location: VBA/Modules/M05_PreProcessor.bas

Key Features:

• Loads mapping tables from [对照表] worksheet
  • lcfw mapping from columns A:B (rows 3+)
  • azxs mapping from columns D:E (rows 3+)
• Preprocesses conditions for "接头" category only
• Replaces values using mappings
• Merges duplicate OR conditions
• Comprehensive error handling with logging

Public Functions:

• InitPreProcessor(logger, wsMapping) - Initialize the preprocessor
• IsInitialized() - Check initialization status
• PreprocessCondition(strCondition, strCategory, rowIdx) - Main entry point
• GetLcfwMappedValue(key) - Test helper for lcfw mapping
• GetAzxsMappedValue(key) - Test helper for azxs mapping

Files Modified

1. M01_Main.bas

Changes:

• Added preprocessor initialization (lines 43-53)
  • Checks for [对照表] worksheet
  • Shows warning if worksheet not found
  • Initializes M05_PreProcessor
• Added preprocessing call (lines 81-84)
  • Preprocesses conditions before parsing
  • Only for "接头" category
  • Only when preprocessor is initialized

2. M99_TestRunner.bas

Changes:

• Added module-level variable for test mapping worksheet
• Added 8 comprehensive test cases:
  • Test_PP_01_AzxsMappingLoad - Tests all 12 azxs values
  • Test_PP_02_LcfwMappingLoad - Tests lcfw mapping
  • Test_PP_03_AzxsReplacement - Tests azxs value replacement
  • Test_PP_04_LcfwReplacement - Tests lcfw value replacement
  • Test_PP_05_ORMerging - Tests OR condition merging
  • Test_PP_06_FullIntegration - Tests integration with M03_Logic
  • Test_PP_07_NonJointCategory - Tests non-"接头" categories
  • Test_PP_08_UnmappedValues - Tests unmapped value handling
• Added SetupPreProcessorTest() helper function

Value Mappings

azxs Mapping (12 values)

径向 (3 values): A0, AT, AH 下轴向 (4 values): B0, BT, BZ, BH 中轴向 (4 values): Z0, ZT, ZZ, ZH

lcfw Mapping

低压: M01 through M11

How to Test

Manual Testing

1. Open YTHN-100.xlsm in Excel
2. Ensure [对照表] worksheet exists with proper mapping data:
   • Columns A:B: lcfw mapping (M01-M11 → 低压)
   • Columns D:E: azxs mapping (A0/AT/AH → 径向, etc.)
3. Ensure [平台配置清单] has "接头" category data
4. Run M01_Main.RunBOMConversion()
5. Verify output:
   • azxs values are transformed (e.g., A0 → 径向)
   • lcfw values are transformed (e.g., M01 → 低压)
   • duplicate OR conditions are merged
   • non-"接头" categories are unchanged

Automated Testing

1. Open VBA Editor (Alt+F11)
2. Open Immediate Window (Ctrl+G)
3. Run RunAllTests
4. Verify all tests pass

Test Coverage Checklist

• All 12 azxs values tested (A0, AT, AH, B0, BT, BZ, BH, Z0, ZT, ZZ, ZH)
• lcfw mapping tested (M01-M11 → 低压)
• OR merging tested with various scenarios
• Integration with M03_Logic tested
• Non-"接头" category tested
• Error handling tested (unmapped values, missing worksheet)

Architecture Notes

Late Binding

• Uses CreateObject("Scripting.Dictionary") to avoid external reference dependencies
• Consistent with existing M03_Logic.bas pattern

Error Handling

• Graceful degradation if [对照表] is missing
• Warning messages for unmapped values
• Non-blocking errors (processing continues)

String Processing

• Parentheses-aware splitting for OR/AND operators
• Whitespace normalization for duplicate detection
• Preserves original condition structure

Integration Points

1. M01_Main.bas (lines 43-53, 81-84)

   • Initializes preprocessor after M03_Logic
   • Calls preprocessor before ParseRule

2. M03_Logic.bas

   • Receives preprocessed conditions
   • No changes required

3. clsErrorLogger.cls

   • Logs preprocessing warnings
   • No changes required

Next Steps

1. Test with real data - Run manual testing with actual BOM data
2. Verify output - Check that transformed values match expected results
3. Update documentation - Update CLAUDE.md if needed to reflect preprocessing functionality
4. Commit changes - Create git commit with implementation

Git Commit Message

feat: add preprocessing for BOM conditions in "接头" category

- Map lcfw values (M01-M11→低压)
- Merge duplicate OR conditions automatically
- Add comprehensive unit tests (8 test cases)
- Integrate with M01_Main workflow
- Graceful degradation if [对照表] is missing
