I am trying to run the 'console show' command. But Tk is not having it.

Error in startup script: invalid command name "console"
while executing
"console show"
(file "p1.tcl" line 4)
Compilation failed.

To my dismay, the manual says,

"Except for TkAqua, this command is not available when Tk is loaded
into a tclsh interpreter with 'package require Tk' as a conventional
terminal is expected to be present in that case."

I guess I will never understand that decision. So what if a terminal
is expected to be present? How about letting that decision up to us?

Anyway, I try to run the script with wish and the same error happens

Any solution to that?

It is also only available on Windows (and maybe Mac) builds.

Linux (Unix) builds don't include it because a 'console' is already
available as the terminal emulator you launch the script from.

So if you are launchin p1.tcl on Linux, you'll get that error if you
try to do 'console show'.

The typical replacement under Linux is tkcon

You don't say.

Then I can't follow the guidance that Michael Niehren gave me
yesterday regarding capturing the output of a tclexecomp packed
executable.

Hello,
regarding console,
there are also differences between wish and tclsh on Windows:
http://www.tcl.tk/man/tcl/UserCmd/wish.htm#M14

One solution would be:
https://wiki.tcl-lang.org/page/console+for+Unix
a wrapper for console.tcl in $tk_library

Also works with Windows.

Thanks.

I ended up just making a text widget and using it as a debugger
pad.

Then I realized it's not possible to do what I wanted to do.
I was hoping I could look inside the internal tclexecomp
file system. I want to source a packed file. I'm not sure that
can be done. Freewrap does that. I think tclexecomp doesn't.

the "console" command is also availiable in the linux version of tclexecomp

call your script with without wrapping
tclexecomp64 p1.tcl

so the "console show" command will work and an extra console window will
be opened. There you can see the Output of stdout and stderr.

Hi Luc,

you have access to the internal tclexecomp filesystem over the
/cvfs
mountpoint. It is mounted read-only on runtime. To take a look you can use
the "normal" filesystem commands like glob, file copy, ...

Greetings,
Michael
