Complete rewrite of filename parser to support new field order where
Subject/Asset moved up and Country/Language moved down, plus new
Social Media field.
BREAKING CHANGE: V2.1 Structure (November 2025)
Old (V1):
[JOB]_[BRAND]_[COUNTRY]_[LANG]_[SUBJECT]_[ASSET]_[SPOT]_[DUR]_[RATIO]_[TRACKING]
New (V2.1):
[JOB]_[BRAND]_[SUBJECT]_[ASSET]_[DUR]_[RATIO]_[SPOT]_[COUNTRY]_[LANG]_[SOCIAL]_[TRACKING]
Field Position Changes:
- Subject Title: Position 5 → 3 (MOVED UP)
- Asset Type: Position 6 → 4 (MOVED UP)
- Duration: Position 8 → 5 (MOVED UP)
- Aspect Ratio: Position 9 → 6 (MOVED UP)
- Spot Version: 7 → 7 (SAME)
- Country Code: Position 3 → 8 (MOVED DOWN)
- Language Code: Position 4 → 9 (MOVED DOWN)
- Social Media: NEW → Position 10
- Tracking ID: Position 10 → 11
New Social Media Field:
- Field: social_media_version
- Position: 10 (after language, before tracking)
- Format: 3 uppercase letters
- Codes: FBP, FBR, IGF, IGR (expandable)
- Optional: Only present for social media assets
Parse Algorithm Changes:
- Positions 1-4 now: Job, Brand, Subject, Asset (fixed)
- Positions 5-11: Pattern-based detection (flexible)
- Duration detected by \d+S pattern
- Aspect ratio detected by \d+x\d+ or contains 'x'
- Spot detected by MST/REF
- Country detected by 2 upper alpha (after ratio)
- Language detected by 2-3 lower alpha (after country)
- Social detected by known codes (after language)
- Tracking ID detected by 6 alphanumeric + optional -N
strip_upload_components() Updated:
Now outputs: [BRAND]_[SUBJECT]_[ASSET]_[DUR]_[RATIO]_[SPOT]_[COUNTRY]_[LANG]_[SOCIAL]
- Includes social media version if present
- Still strips job number and tracking ID
Testing:
All 7 test cases from specification passed:
✅ All fields present
✅ Minimal (no duration/social/tracking)
✅ No duration
✅ No spot version
✅ With -N tracking (folder-only mode)
✅ No social media (most common)
✅ No tracking ID
Example:
Input: 1234567_RAF_TEST_OLV_6S_1x1_REF_GL_it_IGF_abc123.mp4
Parsed: brand=RAF, subject=TEST, country=GL, lang=it, social=IGF
Clean: RAF_TEST_OLV_6S_1x1_REF_GL_it_IGF.mp4
Backward Compatibility:
None - system not live yet, clean cutover to V2.1 format only.
Backup: filename_parser_v1_backup.py contains old version for reference.
