💖 tkerror(3tk) — Tk Built-In Commands 💖

okay bestie, buckle up, because this one is a little vintage situation. we're talking about tkerror, from the Tk built-in commands era. she's iconic but she's also, like, retired. let's get into it 🫶

---

✨ NAME ✨

tkerror — the command that gets invoked to process background errors. yes, background errors. the sneaky ones that pop off when you're not even looking 💀

---

🌸 SYNOPSIS 🌸

tkerror message

---

🎀 DESCRIPTION 🎀

⚠️ note, and this is important: as of Tk 4.1, the tkerror command has been renamed to bgerror. why? because the event loop (which is literally the thing that usually invokes it) is now part of Tcl. so yeah, using the tkerror name is deprecated. it's giving "still here but on thin ice" 🧊

but here's the tea for the nostalgia girlies: for backward compatibility, the bgerror provided by the current Tk version still tries to call tkerror if there is one — or an auto loadable one — so an old script defining that error handler should still work. slay for legacy code, honestly 💅

that said? you should anyhow modify your scripts to use bgerror instead of tkerror, because that support for the old name might vanish in the future. no cap. don't build your whole personality on a deprecated name, bestie 😭

and if that call fails, bgerror posts a dialog showing the error and offering to see the stack trace to the user. very "here's what went wrong, want the receipts?" energy 🧾

now, if you want your own error management, the move is to directly override bgerror instead of tkerror. periodt. that's the assignment 👑

documentation for bgerror is available as part of Tcl's documentation, so go read that one, she's the current main character 💜
