copyparty/bin/hooks/README.md

standalone programs which are executed by copyparty when an event happens (upload, file rename, delete, ...)

these programs either take zero arguments, or a filepath (the affected file), or a json message with filepath + additional info

note: in addition to event hooks (the stuff described here), copyparty has another api to run your programs/scripts while providing way more information such as audio tags / video codecs / etc and optionally daisychaining data between scripts in a processing pipeline; if that's what you want then see mtp plugins instead

after upload

• notify.py shows a desktop notification (example)
• discord-announce.py announces new uploads on discord using webhooks (example)
• reject-mimetype.py rejects uploads unless the mimetype is acceptable

before upload

• reject-extension.py rejects uploads if they match a list of file extensions

on message

• wget.py lets you download files by POSTing URLs to copyparty
