TutCatalogPy2

https://gitlab.com/iborco-software/tutcatalog/tutcatalogpy2

The second Python iteration (2021–2022, Python/PySide2). Described in its own README as "the fourth incarnation" of TutCatalog. Leans into the SQLite cache for fast access/search and adds proper OS integration (Linux .desktop files + a .tc MIME type), but stayed read-only — editing info.tc and the viewer app were both still TODO when it stopped.

File formats

• info.tc — per-tutorial YAML sidecar (a full example ships in examples/info.tc): the familiar field set — publisher, title, author list, released, duration, level, url, the boolean flags (complete/todo/viewed/keep/online), tags/extraTags, learning_paths, rating, and a Markdown description.
• SQLite cache — scanned catalog index (SQLAlchemy; catalog/config.py). Rebuildable.
• .ini — QSettings app state.
• MIME: registers application/x-tc for .tc (Linux user-extension-tc.xml) so the file type is recognized by the desktop.

What it did

Scan folders, parse and display info.tc in a cached, searchable catalog. Editing was not yet implemented. Carried a dedicated scrapper tool for seeding metadata from publisher pages.

Feature ledger

Feature	TutCatalogPy2	rehuco
info.tc sidecar	YAML	Built — .rehu (JSON); .tc read and converted
Display fields	Yes	Built
Edit fields	Never landed	Built
Tags dock: authors and publishers with counts, and flags (complete, error, has info.tc, cover, checked, disk online); click cycles ignore / include / exclude	Yes (tags_dock.py)	TBD as a dock. Filtering: Built for typed tokens (folder, authors, tags, publishers, type) in the table browsers' filter line; click-to-filter only for authors (right-click an authors cell, #460). Not built: filtering by collection or learning path, include/exclude, saved filters. Filtering by flag is not built either
SQLite cache and search	Yes	Built — .rehudb and the filter line
.tc file-type association	Linux MIME	Built for .rehu on Windows, macOS and Linux (application/x-rehuco)
Scraping (scrapper tool)	Yes	Built — ArtStation and Udemy, plus a user script
Duration via ffprobe	Yes	Built
learning_paths, rating, viewed/todo/keep/online flags	Yes	Built as fields

Importing its data

examples/info.tc is the field set rehuco's field schema lists; the adapter applies the renames (tags → advertised_tags, extraTags → extra_tags) and the title/publisher/url → sources fold. The cache needs no import.
