Install Dependencies
Two surfaces:
- System binaries — required:
ImageMagick, exiftool. Optional: libvips-tools, libheif-examples, oxipng, pngquant, jpegoptim, mozjpeg, libavif-bin, libjxl-tools, realesrgan-ncnn-vulkan, darktable-cli.
- Python tools —
imagehash, Pillow (perceptual dedupe). Installed into a plugin-owned uv venv at <data-dir>/venv/.
The plugin invokes Python via <data-dir>/venv/bin/python, so the user's system Python stays untouched and PEP 668 / externally-managed-environment errors never occur.

VENV_DIR="$PLUGIN_DATA_DIR/venv"
Procedure
1. Detect host
uname -s
which apt-get apt brew dnf pacman 2>/dev/null
which uv 2>/dev/null
Record what's available; this drives which install commands you propose.
2. Ensure uv is available
uv is the only hard prerequisite for the Python side. If missing, propose:
curl -LsSf https://astral.sh/uv/install.sh | sh
Ask before running. Fall back to system pip with --break-system-packages only if the user declines — prefer uv.
3. Walk the system-binary matrix
| Tool | Detect | Required? | Install (apt) | Install (brew) |
|---|
magick / convert / identify | which magick || which convert | required | sudo apt install imagemagick | brew install imagemagick |
exiftool | which exiftool | required | sudo apt install libimage-exiftool-perl | brew install exiftool |
fdupes | which fdupes | optional | sudo apt install fdupes | brew install fdupes |
vips / vipsthumbnail | which vips | optional (recommended >500 images) | sudo apt install libvips-tools | brew install vips |
heif-convert | which heif-convert | optional | sudo apt install libheif-examples | brew install libheif |
oxipng | which oxipng | optional | sudo apt install oxipng | brew install oxipng |
pngquant | which pngquant | optional | sudo apt install pngquant | brew install pngquant |
jpegoptim | which jpegoptim | optional | sudo apt install jpegoptim | brew install jpegoptim |
mozjpeg (cjpeg-mozjpeg) | which cjpeg-mozjpeg | optional | cargo install mozjpeg-cli (or binary) |
For each: if missing, stage the install command tagged required/optional. Required tools that are missing block the install — surface that clearly.
realesrgan-ncnn-vulkan and mozjpeg are not in apt — for those, point the user at the upstream releases page rather than auto-downloading. Ask before placing binaries under ~/bin/.
4. Provision the venv
If <VENV_DIR> doesn't exist:
uv venv "$VENV_DIR" --python 3.11
If it exists, leave it.
5. Install Python packages into the venv
| Package | Required? | Used by |
|---|
Pillow | required | dedupe (perceptual), inspection |
imagehash | required | dedupe (perceptual) |
numpy | required (Pillow/imagehash dep) | dedupe |
cairosvg | optional | svg-to-raster (SVG → PNG/PDF). Needs system libcairo2 (preinstalled on most Linux/macOS). |
vtracer | optional | vectorize (raster → SVG). Self-contained wheel (bundled Rust binary). |
Stage:
source "$VENV_DIR/bin/activate"
uv pip install Pillow imagehash numpy
uv pip install cairosvg vtracer
If cairosvg import fails at runtime with a libcairo error, prompt the user to install the system lib: sudo apt install libcairo2 (Linux) / brew install cairo (macOS).
6. Verify
After installs, re-run the detect commands and report a green/red status table per tool. Surface install commands the user still needs to run themselves (sudo, cargo).
Output
Single status report:
- Required system bins: present / missing.
- Optional system bins: present / missing (with one-line reason to install each).
- Venv: provisioned at
<VENV_DIR>, Python <version>.
- Python packages: installed.
Refuse to mark "OK" if any required tool is missing.
