trackloom 0.1.0

Safe CLI for comparing and merging music libraries

trackloom

trackloom is a safe CLI for comparing two music libraries and merging tracks from library A into library B without overwriting existing files or deleting data.

It extracts normalized artist, album, and song fields from file paths and embedded tags, compares exact and fuzzy matches, builds a copy/add plan, lets you review ambiguous matches, and applies the plan with dry-run and reporting support.

Why use it

• Safe by default: no overwrite, no delete, confirmation required for writes
• Workflow-oriented: compare, plan, review, apply
• Handles fuzzy matching and duplicate preference logic
• Supports dry-run, JSON output, reports, and quarantine-based replacement flow
• Works with common music formats via mutagen

Install

From PyPI:

python3 -m pip install trackloom

From a source checkout:

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install --upgrade pip setuptools wheel
python3 -m pip install -e .

After install:

trackloom help

Quickstart

trackloom compare /path/to/A /path/to/B --json > /tmp/compare.json
trackloom plan /path/to/A /path/to/B --write-plan-json /tmp/plan.json
trackloom review /path/to/A /path/to/B --decisions-file /tmp/decisions.json \
  --write-plan-json /tmp/reviewed-plan.json
trackloom apply /path/to/A /path/to/B --from-plan-json /tmp/reviewed-plan.json --dry-run

For a real run, replace the final command with --yes after checking the plan and dry-run output.

Commands

• parse: catalog parsed fields from one or two directories
• compare: find exact and fuzzy matches and recommended actions
• plan: build copy/add operations to bring A into B
• review: resolve manual_review items interactively
• apply: execute the plan safely, with dry-run and reports
• doctor: run environment and CLI diagnostics

Safety model

• Existing destination files are never overwritten.
• Delete operations are never performed.
• Replacement cleanup is quarantine-only and only applies to replace_in_b_with_a.
• Real writes require confirmation by default.
• apply continues past per-file I/O failures and reports them.
