When you use a open/pipe command like [open "| xyz ...]", is it possible
to configure it in both read and write modes? So I can write to it to
send info to xyz and read its output?

This is trivial for you to discover on your own:

$ rlwrap tclsh
% set fd [open "|cat -" {RDWR}]
file5
% fconfigure $fd -buffering none
% puts $fd hello
% gets $fd
hello
% exit

Note that the '-buffering none' is to be sure that the first puts of
'hello' got flushed to cat to be returned.

You are right; give it to mental fog.

I have been using the gemini AI (gemini.google.com) a lot more lately, since I was surprised by how well it knows Tcl coding.

I gave it the same question from your first post, and then I provided the text of this thread and asked it what it thought about it.

It then said:

"I'd be glad to provide a response that incorporates the best aspects of previous responses, addresses potential issues, and aims to be superior to a human response that might be dismissive:"

It followed that up with some info on buffering in tcl pipes, and a complete explanation of this thread's responses, and some recommendations.

The only thing it left out was,

I'll be back!
