# Curator
Curator is a PySide6 desktop app for managing a **Jellyfin-first movie and series
library**. You import video files into a managed **pool**; Curator identifies them
through **TMDb**, names and lays them out the way Jellyfin expects, and can
generate a genre-split **miniDLNA / Filmotéka** tree of hardlinks for dumb DLNA
players — without ever duplicating the video data on disk.

Metadata (posters, plots, `.nfo` files) is Jellyfin's job; Curator owns the files,
their names and the library structure.

- **Pool index** — Curator's own metadata (TMDb id, ČSFD link, versions, tags,
library settings) lives in one `.Curator.!index` JSON file at the pool root.
- **miniDLNA output** — a generated tree of **hardlinks** into the pool, built
from the genres/years/ratings in Jellyfin's NFO files. It is disposable: delete
it and regenerate it at any time.

## Features
- Import movies and episodes with a mandatory **TMDb id**; Czech titles come from
TMDb, with **ČSFD** as a fallback and as a bridge for finding the right TMDb id.
- **Multiple versions** of one film (2D/3D, 4K, director's cut) and **multi-part**
films and episodes, named so Jellyfin groups them.

- Subtitle sidecars follow their video through renames.
- Duplicate check, video integrity check (FFmpeg), library statistics.
- Jellyfin integration: trigger a library scan, read what Jellyfin has.

- Jellyfin integration: trigger a library scan, verify the pool against it.
- miniDLNA tree scoped per library, with "Tipy dne" and "Nově přidané" folders.
## Requirements
- [uv](https://docs.astral.sh/uv/) — manages Python 3.14 and all dependencies
- Rust 1.85+ (`rustup`), for building
- `ffmpeg` / `ffprobe` on `PATH` — optional, for the integrity check

| `ENV_DEBUG` | `true` enables debug mode |
| `ENV_DEBUG` | `true` enables debug logging and the `-DEV` title |

the global config (`~/.config/curator/.Curator.!gtag` on Linux, overridable with

## Running
```bash
uv sync
uv run python Curator.py
cargo run --release
```
## Development
```bash
uv run pytest # tests
uv run ruff check # lint
uv run ruff format # format
uv run mypy # type checking
cargo fmt # format
cargo clippy -- -D warnings # lint
cargo test # unit tests + headless UI tests
cargo doc --open # API reference
```
Detailed documentation — architecture and a per-module reference — is in
[`docs/`](docs/README.md).
`cargo run --example screenshot -- out.png [--action edit]` renders the window
offscreen to a PNG. Architecture and module overview: [`docs/`](docs/README.md).
## Building a standalone executable
## Building
```bash
uv run python prebuild.py
uv run pyinstaller Curator.spec --noconfirm
cargo build --release
```
The result is a single self-contained `dist/Curator` executable.
The result is `target/release/curator`, plus `target/release/tipy-dne` — a
standalone "Tipy dne" refresher meant for a systemd timer (see
`scripts/tipy-dne.service` / `.timer`).
