NC Filtered Git Diff

Compare NC files against their Git HEAD version, with all noise patterns defined in your NCComparisonConfig.json hierarchy filtered out before the diff is shown.

Features

• Right-click any .nc file in the Explorer → Compare with Git HEAD (filtered)
• Automatically loads and merges the 3-level NCComparisonConfig.json hierarchy:
  1. Global — {Git-Root}/_SOFTWARE/DATA/NCComparisonConfig.json
  2. PTA-level — {PTA-Folder}/NCComparisonConfig/NCComparisonConfig.json
  3. PP-specific — {PTA-Folder}/NCComparisonConfig/{PP-Name}/NCComparisonConfig.json
• Opens the VS Code built-in side-by-side diff editor with cleaned text
• Graceful degradation: if a config level is missing, it is silently skipped

Folder Structure Expected

{Git-Root}/
├── _SOFTWARE/DATA/NCComparisonConfig.json          ← Level 1 (global)
└── {PTA-Folder}/                                   ← identified by "Baseline Output" subfolder
    ├── Baseline Output/
    │   └── {PP-Name}/                              ← post-processor name
    │       └── *.nc                                ← files to compare
    └── NCComparisonConfig/
        ├── NCComparisonConfig.json                 ← Level 2 (PTA)
        └── {PP-Name}/
            └── NCComparisonConfig.json             ← Level 3 (PP-specific)
