tcl::chan::fifo2(3tcl)

✨ tcl::chan::fifo2 ✨

okay bestie, you're in the tcl::chan::fifo2 page of the Reflected/virtual channel support manual (that's the 3tcl section, iykyk) 💅 and it's literally all about in-memory interconnected fifo channels. no cap. let's go 🦋

🌸 NAME 🌸

tcl::chan::fifo2 — in-memory interconnected fifo channels 🎀

---

✨ SYNOPSIS ✨

package require Tcl 8.5 9

package require TclOO

package require tcl::chan::events ?1.1?

package require tcl::chan::halfpipe ?1.1?

package require tcl::chan::fifo2 ?1.1?

::tcl::chan::fifo2

like, that's the whole vibe right there 💖

---

💜 DESCRIPTION 💜

so the tcl::chan::fifo2 package hands you a command that creates pairs of channels that live purely in memory 🧠✨ and are connected to each other in a fifo manner. what you write into one half of the pair, you can read out of the other half — in the same order. first in, first out, periodt 💅

one particular application for this is communication between threads, where you move one half of the pair over to the thread you want to talk to 📬🫶

and like, this is equivalent to the fifo2 channels that the Memchan package provides — except this one is written in pure Tcl, not C 👑. on the other hand, Memchan is usable with Tcl 8.4 and before, whereas this package requires Tcl 8.5 or higher, and TclOO. so, tradeoffs, bestie 😭

also, the internal TclOO class implementing the channel handler is a sub-class of the tcl::chan::events framework 🌈

---

🎀 API 🎀

• ::tcl::chan::fifo2 — this command creates a new connected pair of fifo channels and returns their handles, as a list containing two elements 📝✨
