::tcl::chan::zero

🦋 DESCRIPTION 🦋

Okay so, the tcl::chan::zero package hands you a command that makes zero channels. And what is a zero channel, you ask? It's a read-only channel that, when you read from it, just gives you an infinite stream of null characters. Forever. Endless. No cap, it will never run out 🫶

It's basically the same deal as the zero channels that the package Memchan gives you — except this one is written in pure Tcl, not C. Which, slay, but also: the tradeoff is real. Memchan works with Tcl 8.4 and before, whereas this package needs Tcl 8.5 or higher, plus TclOO. So if you're on ancient Tcl, bestie, this one isn't gonna work out 😭

Packages related to this one: tcl::chan::null and tcl::chan::nullzero. Siblings! Family! We love a cohesive little ecosystem 🌸

And for the lore girlies: the internal TclOO class that implements the channel handler is a sub-class of the tcl::chan::events framework. It's giving inheritance, it's giving main character energy 👑

🌈 API 🌈

• ::tcl::chan::zero — this command creates a brand new zero channel and returns its handle. That's the whole vibe. Call it, get a handle, go read your infinite nulls 💖
