Provided said 'graphic consoles' are based off the Tk text widget, then
yes, as the text widget already supports inserting and display of Tk
images.

So you'd need to modify the console to include a display command to
display an image.

Doing "puts [image data]" would just get you the text encoded image
data, so better to have something like:

display image

Where 'display' is built in to the console and includes the small
amount of code to insert the image named 'image' into the next line of
the console text widget.

Ok, and how can I get the "widget" associated with the graphic
console? for example, if I run tkcon and try to get the window name
with:

winfo name .

On that I suggest you look into how the console is implemented. Tkcon
is just a Tcl/Tk script. I've not gone looking because I do my Tk
programming on Linux, where I already have a proper, real, console (xterm/rxvt/urxvt/etc.) and so I seldome ever use Tkcon. And the few
times I do it is only to connect to a running Tk instance for a quick inspection.

I get a message saying Tk is not loaded and asking me to retry the
command after loading Tk, doing so a new Tk main window named "tkcon"
appears and now tk commands refer to that window, not to the window
of Tkcon console itself.

Tkcon's probably running the console in an interpreter separate from
the one that handles Tkcon's own windows. Again, inspect the Tkcon
source, it is all just Tcl.

So assuming wish console is a Tk window itself, how can I get its
widgets and send tk commands to them?

Also, unsure. Look for the Tcl script that is lauched to make that
console and inspect how it is built to do its job. It is probably
running in a separate interpreter, so you'd need to find out the name
and then send commands into that interpreter.

If wish console is a graphic program but not a tk program, then I
suppose I have to use graphic API beneath (windows, gtk...) to
provide access to wish painting area and provide commands to interact
with it like the one you suggest to diplay an image.

Tkcon is just a Tcl/Tk script. I believe the basic 'console' that is
provided for windows builds is just a Tcl/Tk script as well. Dig into
the files installed for Tcl/Tk and see what you find.

A maybe better alternative is to program a console in Tk itself,

I.e., just what Tkcon is, and what the basic console is as well (I
believe).

I assume wish is a window program ie a graphic one, at least this seems to be true in the case of windows OS, like is said in tk docs:

"Note that on Windows, the wishversion.exe program varies from the tclshversion.exe program in an additional important way: it does not connect to a standard Windows console and is instead a windowed program. Because of this, it additionally provides

access to its own console command."

https://www.tcl.tk/man/tcl/UserCmd/wish.html

So, it should be possible to write an image to the main window of wish and get displayed in the wish window.

For example, it would be cool if you can write code like this:

% image create photo -file "anImage.png"
image1
% puts [image1 data]

and you get below the last line the image displayed in the wish console in similar way that it works in racket repl or smalltalk transcript window or factor listener.

In tcl/tk 8.7 and 9.0 both toplevel and frames can include background images (TIP 262). For demo code, see here:

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

One thing this can do is allow "skins", perhaps along with using the the place geom manager.

The windows console can be tweaked using the console eval command to add images. See

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

and open the first discussion. Also, you can get a linux console if you use the code in

https://wiki.tcl-lang.org/page/console+for+Unix

I have added a few images to my consoles just for fun, for a few fancy buttons.

If you use tkcon, which is much better than the built-in console
anyway, it is right here in the front page of it:

interesting links, specially the info about console

The windows console can be tweaked using the console eval command to add images. See

yes, reading your links and the one by C.Gollwitzer and tkcon source I realized tkcon provides an api with several commands, in particular it provides tkcon console to access to the text widget... it would be easier simply to extend this api with the

commands you like

I use the built in console to be certain I have somewhere to output a message log. No package require, no sourcing, etc. Even androwish has a console. Only unix is left out, but in under 200 lines of code, which I just include in my own programs, I can
be sure of having a console everywhere my programs will run. Tkcon is 6500 lines, and it's not always available. I think of it more as a debugger than a simple console.

I suspect your needs are different and so tkcon may very well be the ticket for you.
