The original script (J621-Django/extras/fish_greeting system) downloaded
image bytes from /random/?rating=X and read the X-File-* headers. The new
API answers with JSON and a signed link, so the greeting now:
- asks /api/random/?fastfetch=1&rating=<mode> for JSON;
- parses url/j_id/filename/md5 with jq, python3, or a grep/sed fallback;
- downloads the signed link and keeps the original display path (fastfetch
kitty/kitty-icat logos, gifsicle preprocessing for GIFs, recursion guard,
logging with rotation, greeting_mode 0/1/2 = NSFW/SFW/Questionable);
- is configured through ~/.config/j621Greeting/config.fish or universal
variables (J621_BASE, J621_WEB, J621_TOKEN, J621_FASTFETCH_CONFIG) instead
of a hardcoded host, and prints the /detail/<J-ID> link on J621_WEB;
- reports the API's own 404 message when a rating has no images, and keeps
curl quiet so failures do not spill into the greeting.
extras/fish_greeting/ contains the function, an install.fish (copies it into
the fish functions dir, creates the config once, checks dependencies) and a
README with the old-vs-new table and troubleshooting. The existing
gm-switch helper and .desktop launchers keep working (same mode file).
Tested with fish 4.9.3: syntax check on every file, guest and token runs
against the dev API (unsigned vs signed URLs), the empty-rating and
unreachable-API paths, and the grep/sed fallback with jq and python3
unavailable.
Backend: GET /api/random/ (aliases /random and /random/) returns a random
library image with:
- rating=s,q,e filtering (comma separated, default any);
- fastfetch mode (?fastfetch=1 or any User-Agent containing "fastfetch")
that only considers png/jpg/gif - what terminal viewers can show;
- JSON with j_id, filename, extension, rating, size, e621 id plus absolute
url/download_url/thumbnail_url. Authenticated callers get signed URLs so
fastfetch and image viewers can load them without headers; guests get
unsigned URLs and never receive hidden_from_guests items.
Tests: apps/library/tests/test_random.py (8 tests) covering the response
contract, guest signatures, image-only default, the fastfetch format
restriction (flag and User-Agent), rating filters, guest visibility and the
short alias.
Frontend: /random page with rating pills, R to roll, Open/Download and a
library link, plus navigation and command palette entries; needs a backend,
hidden in local mode.
nginx: /random negotiates on Accept so browsers keep getting the SPA while
scripts get the JSON (verified with the proxy and frontend containers).
Also fixes a regression from the SSRF change: the guest download proxy
still referenced the removed 'parsed' variable on its success path, so
every proxied download would have 500'd. Redirect hops are now covered by
tests with a mocked requests.get.

a termination-on-breach clause with a 30-day cure, and a clearer
'no licence' wording in section 0. README gains a Licence section.
Backend (Django 6.1 + DRF):
- Token auth with a custom User model (register/login/logout/me)
- Library models (MediaItem, MediaLocation) and REST endpoints
- File list/detail with search, rating filter, sorting, pagination
- Multipart upload with optional rating/tags/notes
- Range-aware media serving (video seeking) and ffmpeg thumbnails
- scan_files management command for the watched folder
Frontend (React 19 + Vite + TypeScript):
- Catppuccin Mocha design tokens from the design docs
- App shell, token persistence, protected routes
- Library grid with filters, file detail with custom data editor
- Upload page with per-file progress via XHR
- Dev proxy to the Django API
