Re: [TCLCORE] Report of biweekly telco on 3rd of November at 12:00 UTC

Hi Harald:

Regarding,  TIP 561: Console command for Linux/Unix

In my testing, via a source console.tcl, it does in fact allow input both
from the console and the terminal. It even works with rlwrap. What I fixed
in the most recent version is the opening and closing of the console
window. While the console window is open, no prompts go to the terminal,
however. But you can type in commands and the output will go to the console
window.

On closing, stdout, and stderr both revert to the terminal, and a prompt
returns in the terminal window. On issuing another console show, it will
now re-open, just where it was and further output to stderr (in red) and
stdout go to the console again. That was in my latest fix. Prior to that I
was deleting the console window on closing it, which was a mistake. Please
try the latest code.

I also changed the font size shortcuts to also allow for control-keypad +
and - and also control = which is a non-shifted + for convenience.

The wrapper code in the tip would provide backward compatibility, i.e. no
console would open automatically when running wish, since linux/unix users
wouldn't expect that. On the first console show command the wrapper will
invoke the contents of console.tcl and then remove itself.
