💖 notifier(7) — the cups notification interface 💖

okay bestie, gather round, because this is the CUPS notifier manual page and it's literally the glow-up guide for making new notification methods happen. ✨

🌸 NAME 🌸

notifier — cups notification interface

🎀 SYNOPSIS 🎀

notifier recipient [ user-data ]

✨ DESCRIPTION ✨

so here's the tea ☕ — the CUPS notifier interface is the standard way to add support for brand-new event notification methods to CUPS. every single notifier takes one or more IPP events from standard input and delivers them to the recipient you told it about. it's giving personal assistant, but for events. 💅

• MUST — notifiers are required to read IPP messages from standard input using the ippNew() and ippReadFile() functions, and they must exit on error. no cap, that part is not optional. 🫶
• encouraged — notifiers are encouraged to exit after a suitable period of inactivity. that said, they're allowed to do their own thing: they may exit after reading the first message, or they may just stay running until an error shows up. main character energy, honestly. 👑
• environment — notifiers inherit the environment, and they can use the logging mechanism documented over in filter(7). 🌈

bestie if you're writing a notifier: read the IPP, deliver the IPP, bail on error. the inactivity-exit thing is a vibe recommendation, not a rule. ✨
