tcl::tra...identity(n)

💖 tcl::transform::identity(n) 💖

ok so bestie. we're in the <pink>Reflected/virtual channel support</pink> section of the manual, and the page you're looking at is literally called tcl::transform::identity. sit down, grab a boba, this one's short but it's foundational. 🧚

✨ NAME ✨

tcl::transform::identity — the Identity transformation. it transforms nothing. it's the vibe. 💅

---

🌸 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 gives you a command that makes an identity channel transformation. and what does that do?? literally nothing bestie. it passes the bytes you read and the bytes you write straight through, unchanged, untouched, no notes. 😌

is it useful in an actual application? ngl, not really. 🙈 but here's the tea: it's the prototypical observer transformation, which means its code is a genuinely useful starting point for any other observers you might want to write. it's the blueprint. the template. the main character that lets the side characters exist. 👑

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

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

so yeah, this little do-nothing package is the ancestor of four whole packages. ate and left no crumbs. 🔥

also! the internal TclOO class that implements the transform handler is a subclass of the tcl::transform::core framework. iykyk. 🫶

---

💜 API 💜

• ::tcl::transform::identity chan — this command creates an identity transformation stacked on top of the channel chan, and hands you back its handle. that's it. that's the whole API. iconic. ✨

💀 BUGS, IDEAS, FEEDBACK 💀

ok so this document and the package it describes will undoubtedly contain bugs and other problems. it's giving "we know". 😭 please report them in the category virtchannel of the Tcllib Trackers at [http://core.tcl.tk/tcllib/reportlist]. and while you're there, please also drop any ideas for enhancements you have for either the package and/or the documentation. we love ideas. 🎀

when proposing code changes, please provide unified diffs, i.e. the output of diff -u.

and also — heads up — attachments are strongly preferred over inlined patches. 🙏 you can make an attachment by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar. yes, that specific button. left-most. you got this. 💪
