# Schenesort v2.4.1

![Collage example](docs/collage.png)

A cli tool for managing wallpaper collections with model generated metadata, sweet tui, and sql metadata querying.

schenesort takes a directory of random wallpapers, with random filenames, and uses olama with a decent vision model to:

- look at each wallpaper
- rename the wallpaper to something sensible
- drop a XMP sidecar with metadata about the file

Once you have a collection of wallpapers re-named with metadata sidecars, run the indexer over it to create a sqlitedb
that can be queried to retrieve suggestions based on tags, colours, names and the like. Then use `get` to get a
wallpaper path `feh $(schenesort get -1 -p)` or `hyprctl hyprpaper wallpaper "eDP-1,$(schenesort get -1 -p)"`

## Installation

```bash
uv tool install schenesort
```

For development:

```bash
git clone https://github.com/sthysel/schenesort.git
cd schenesort
uv sync
```

## Quick Start

To generate metadata you need a olama server serving llava nearby, it takes a minute to set one up see [ollama
setup](./ollama-setup.md).

```bash
# Generate metadata for images
schenesort metadata generate ~/wallpapers -r

# Index the collection
schenesort index ~/wallpapers

# Generate thumbnails for gallery
schenesort thumbnail ~/wallpapers -r

# Browse with gallery (thumbnail grid with filters)
schenesort gallery

# Browse single images with TUI
schenesort browse ~/wallpapers

# Query wallpapers
schenesort get --mood peaceful --screen 4K
schenesort get -1 -p | xargs feh  # random wallpaper
```

**Keyboard shortcuts:**

| Key          | Action         |
|--------------|----------------|
| `j` / `Down` | Next image     |
| `k` / `Up`   | Previous image |
| `g` / `Home` | First image    |
| `G` / `End`  | Last image     |
| `+` / `-`    | Zoom in/out    |
| `q`          | Quit           |

The TUI uses textual-image for rendering, which auto-detects terminal graphics support (Sixel, iTerm2, Kitty).

## Gallery Browser

![Gallery example](docs/gallery.png)

Browse your indexed collection with a thumbnail grid and filter panel:

```bash
# Open gallery browser
schenesort gallery

# Pre-filter results
schenesort gallery --mood peaceful
schenesort gallery --tag nature --style photography
```

The gallery requires an indexed collection (`schenesort index`) and cached thumbnails for fast loading.

### Generate Thumbnails

```bash
# Generate thumbnails for a directory
schenesort thumbnail ~/wallpapers

# Recursive with progress bar
schenesort thumbnail ~/wallpapers -r

# Force regenerate all thumbnails
schenesort thumbnail ~/wallpapers --force

# Clear thumbnail cache
schenesort thumbnail ~/wallpapers --clear
```

Thumbnails are cached at `~/.cache/schenesort/thumbnails/` (320x200 JPEG).

**Gallery keyboard shortcuts:**

| Key              | Action                |
|------------------|-----------------------|
| `j` / `Down`     | Move down             |

|------------------|-----------------------|
| `j` / `Down`     | Next image            |
| `k` / `Up`       | Previous image        |
| `Escape` / `q`   | Back to grid          |

## Collection Indexing and Querying

Build a SQLite index for fast querying across your entire collection:

```bash
# Build/update the index
schenesort index ~/wallpapers
schenesort index ~/wallpapers --rebuild   # rebuild from scratch
schenesort index ~/wallpapers --prune     # remove deleted files

# Query wallpapers
schenesort get --tag cyberpunk
schenesort get --mood peaceful --style photography
schenesort get --screen 4K --subject landscape
schenesort get --color blue --time sunset
schenesort get --min-width 3840
schenesort get -q "mountain"              # text search

# Random selection
schenesort get --random -n 10             # 10 random wallpapers
schenesort get -1                         # single random wallpaper
schenesort get -1 --mood dramatic         # random with filter

# Browse results in TUI
schenesort get --mood peaceful --browse   # open matches in browser
schenesort get --style photography -b     # short form

# For scripting (paths only)
schenesort get -1 -p                      # just the path
feh $(schenesort get -1 -p)               # set random wallpaper
hyprctl hyprpaper wallpaper "eDP-1,$(schenesort get -1 -p)"

# View collection stats
schenesort stats
```

The database is stored at `$XDG_DATA_HOME/schenesort/index.db` (default: `~/.local/share/schenesort/index.db`).

## Collage Generation

Create a collage grid from wallpapers matching query criteria:

```bash
# Create a 6x6 collage (default)
schenesort collage output.png --mood peaceful

# Create a 4x4 collage of landscape images
schenesort collage wall.png --subject landscape --cols 4 --rows 4

# Custom tile size (default: 480x270)
schenesort collage collage.png --tile-width 640 --tile-height 360

# Combine filters
schenesort collage night_cities.png --time night --subject urban --cols 3 --rows 2
```

`schenesort collage landscape.png --cols 4 --rows 4 --tile-width 640 --tile-height 360 --tag landscape`

![Collage example](docs/landscape.png)

| Option          | Description                          | Default |
|-----------------|--------------------------------------|---------|
| `--cols`        | Number of columns                    | 6       |
| `--rows`        | Number of rows                       | 6       |
| `--tile-width`  | Width of each tile in pixels         | 480     |
| `--tile-height` | Height of each tile in pixels        | 270     |
| `--random`      | Select images randomly               | True    |

All `get` query filters are supported: `--tag`, `--mood`, `--color`, `--style`, `--subject`, `--time`, `--screen`, `--min-width`, `--min-height`, `--search`.

## Metadata Management

Store metadata in XMP sidecar files (`.xmp`) alongside images without modifying the original files.

### Generate Metadata using ollama

```bash
# Preview what would be generated
schenesort metadata generate ~/wallpapers --dry-run

# Generate metadata and rename files
schenesort metadata generate ~/wallpapers -m llava

# Generate without renaming
schenesort metadata generate ~/wallpapers --no-rename

# Overwrite existing metadata
schenesort metadata generate ~/wallpapers --overwrite

# Use remote Ollama server
schenesort metadata generate ~/wallpapers --host http://server:11434
```

### Update Dimensions Only

Add dimensions to existing sidecars without re-running AI inference:

```bash
schenesort metadata update-dimensions ~/wallpapers -r
```

### Manual Metadata

```bash
# Show metadata
schenesort metadata show image.jpg

# Set fields manually
schenesort metadata set image.jpg -d "Mountain sunset landscape"
schenesort metadata set image.jpg -t "nature,sunset,mountains"
schenesort metadata set image.jpg -a "peaceful"  # add tag
schenesort metadata set image.jpg -s "https://unsplash.com/..."
```

### Embed into Image Files

Write metadata directly into images (requires `exiftool`):

```bash
schenesort metadata embed ~/wallpapers -r
```

## Filename Sanitation

The `sanitise` command makes filenames Unix-friendly:

```bash
schenesort sanitise ~/wallpapers --dry-run
schenesort sanitise ~/wallpapers -r
```

| Rule                        | Example                             |
|-----------------------------|-------------------------------------|
| Lowercase                   | `HelloWorld.JPG` → `helloworld.jpg` |
| Spaces → underscore         | `my file.jpg` → `my_file.jpg`       |
| Remove punctuation          | `file(1)!.jpg` → `file1.jpg`        |
| Collapse underscores        | `a___b.jpg` → `a_b.jpg`             |
| Strip leading/trailing `_-` | `_file_.jpg` → `file.jpg`           |

## Cleanup Orphaned Sidecars

Delete XMP sidecar files that have no corresponding image:

```bash
schenesort cleanup ~/wallpapers --dry-run
schenesort cleanup ~/wallpapers -r
```

## Configuration

Schenesort follows XDG Base Directory spec:

- Config: `$XDG_CONFIG_HOME/schenesort/config.toml` (default: `~/.config/schenesort/config.toml`)
- Data: `$XDG_DATA_HOME/schenesort/index.db` (default: `~/.local/share/schenesort/index.db`)

```bash
# Show current config
schenesort config

# Create default config file
schenesort config --create
```

Config file format:

```toml
[ollama]
# Ollama server URL (leave empty for localhost:11434)
host = "http://server:11434"

# Default vision model
model = "llava:13b"

[paths]
# Default wallpaper collection path
wallpaper = "~/wallpapers"
```

Command-line options override config file settings.

## Ollama Setup (Arch Linux)

```bash
# Install
yay -S ollama ollama-cuda  # for NVIDIA GPU

# Start service
sudo systemctl enable --now ollama

# Pull a vision model
ollama pull llava           # ~4GB
ollama pull llava:13b       # ~8GB, better quality

# List available models
schenesort models
```

## Yazi Plugin

A [Yazi](https://yazi-rs.github.io/) previewer plugin that displays XMP metadata alongside image previews.

### Installation

```bash
# Copy plugin
mkdir -p ~/.config/yazi/plugins/schenesort.yazi
cp schenesort.yazi/main.lua ~/.config/yazi/plugins/schenesort.yazi/

# Install exiftool config for custom namespace
mkdir -p ~/.config/ExifTool
cp schenesort.yazi/schenesort.config ~/.config/ExifTool/

# Install exiftool
sudo pacman -S perl-image-exiftool  # Arch
```

Add to `~/.config/yazi/yazi.toml`:

```toml
[plugin]
prepend_previewers = [
    { mime = "image/*", run = "schenesort" },
]
```

See [schenesort.yazi/README.md](schenesort.yazi/README.md) for details.

## XMP Sidecar Format

```text
~/wallpapers/
├── mountain_sunset.jpg
├── mountain_sunset.jpg.xmp   ← metadata stored here
├── cyberpunk_city.png
└── cyberpunk_city.png.xmp
```

Metadata is stored in standard XMP format, compatible with digiKam, darktable, and Lightroom.

## Screen Size Recommendations

Images are tagged with recommended screen sizes based on resolution:

| Screen          | Resolution |
|-----------------|------------|
| 8K              | 7680x4320  |
| 5K              | 5120x2880  |
| 4K              | 3840x2160  |
| Ultrawide 4K    | 5120x2160  |
| Ultrawide 1440p | 3440x1440  |
| 1440p           | 2560x1440  |
| 1080p           | 1920x1080  |
| 720p            | 1280x720   |

An image is recommended for a screen size if it can cover the screen without upscaling.
