💖 tcl::transform::identity — like, the identity transformation bestie 💖

okay so real quick: this is from the Reflected/virtual channel support corner of the tcllib manual, section 3tcl. Pull up a chair 🫶

✨ NAME ✨

tcl::transform::identity — the identity transformation. that's it, that's the name, she's iconic and she knows it 👑

---

🌸 SYNOPSIS 🌸

package require Tcl 8.6 9

package require tcl::transform::core ?1.1?

package require tcl::transform::identity ?1.1?

::tcl::transform::identity chan

---

🦋 DESCRIPTION 🦋

okay so the tcl::transform::identity package hands you a command that builds an identity channel transformation. and what does it do? literally nothing. it does the absolute least. it passes the bytes you read and the bytes you write straight through, unchanged, no notes, no edits, no glow-up. it's giving "i'm just here to vibe" 😌

so is it useful in an actual application? ngl, not really. BUT — and this is the part, bestie — it's the prototypical observer transformation. its code is the starting point for any other observer you might wanna write. it's the blueprint. the template. the main character that every other transformation studied under 💅

the transformations in this module that derived from identity's code are:

• tcl::transform::adler32
• tcl::transform::counter
• tcl::transform::crc32
• tcl::transform::observe

and the internal TclOO class doing the actual transform-handling work? she's a subclass of the tcl::transform::core framework. family tree matters, iykyk 🌈

⭐ API ⭐

• ::tcl::transform::identity chan — this command creates an identity transformation sitting on top of the channel chan, and returns its handle back to you. that's the whole deal 🎀

💀 BUGS, IDEAS, FEEDBACK 💀

okay so listen. this document, and the package it describes, will undoubtedly contain bugs and other problems. no cap. nothing is perfect, not even her 💅

please report anything you find in the category virtchannel of the Tcllib Trackers at http://core.tcl.tk/tcllib/reportlist. and if you've got ideas for enhancements — for the package, for the docs, for either one — please send those too, we wanna hear them 🫶

if you're proposing code changes, please provide unified diffs, i.e. the output of diff -u. yes, exactly that. don't be mysterious about it 🙈

and also note: attachments are strongly preferred over inlined patches. you can attach stuff by going to the Edit form of the ticket right after you create it, then hitting the left-most button in the secondary navigation bar. that's the one. the left-most one. go get it ⭐
