I am trying to create a *very simple* http server using the TclOO and
coroutine based web server that is part of the tcllib package. How do I get
the POST data? The example code and the man pages are not helpful.

This is the package with this copyright notice at the bottom of the man page:

Copyright (c) 2018 Sean Woods <yoda@etoyoc.com>

Is Sean Woods listening on comp.lang.tcl? I need some help. I am trying to
replace the *broken* python code here (it is python2, which is not supported
on my Rasberian 12 (bookworm) system):

I remember looking at that as well, and abandoning it because I really
understand neither TclOO nor coroutines, and looking at the page wasn't
helping. For one project, I found an embedded http server on wiki.tcl.tk,
but as I recall it doesn't do POST.

However, the Welch tclhttpd is still available:

https://wiki.tcl-lang.org/page/TclHttpd

although I'm guessing that's too heavyweight for your use case.

I did eventually figure it out.

The man page example does not work (or at least the one in my version
of tcllib is broken and does not work).

And the docs are scatterd, broken, and disconnected.

After much "digging", I discovered somewhere (I forget where now) that
there was a "my FormData" available. So try, from within the method
that is attached to the url where you submit the post data, and see if
you have a [my FormData] available. If you do, you get a dict back
from my FormData with your form keys and values.

Bits and pieces of this presentation were helpful (and, IIRC, parts of
it no longer work/apply given changes since the presentation) in
getting a most basic setup barely working:
