FUNCTION::WARN(3stap)

💖 FUNCTION::WARN(3stap) — the Logging Tapset one 💖

okay bestie, so this is FUNCTION::WARN from the Logging Tapset, and it's literally the "hey, heads up" function. no cap, she's simple and she's iconic for it.

---

✨ NAME ✨

function::warn — send a line to the warning stream 🫶

---

🌸 SYNOPSIS 🌸

warn(msg:string)

---

🎀 ARGUMENTS 🎀

• msg — the formatted message string. that's the whole vibe, that's the message you're sending out into the world 💅

---

🦋 DESCRIPTION 🦋

so here's what she does: this function sends a warning message immediately to staprun. like, no waiting around, no queue, she goes straight there. main character energy fr fr.

and ALSO — if the bulk transport (relayfs) is being used, the message gets sent over that too. so it can go both ways, she's flexible like that ✨

one lil detail that's actually so thoughtful: if the last character of your message is not a newline, then a newline gets added for you. automatic. chef's kiss. no more cursed run-together log lines 💖
