Hate the fact that you can cannot revert the termtitle to it's previous value. A mechanisme like push/pop titles would be more convenient. Anchoring metadata to some text (like <a> links in HTML) for terminal emulator to understand instead of regex.

I would suggest asking authors of libraries like python_prompt_toolkit who likely have ideas.

changing terminal-titles is just a google search away. or perhaps i am missing something fundamental. may you please elaborate? thanks!

Yes I'm aware of the ansinescape sequence to _set_ the termtitle. But you can't _restore_ previous termtitle without knowing them (or existing current program). In my case with IPython I want a termtitle that say "busy" when computation is in progress otherwise get back to it's initial value of before starting IPython. I can't do that, because I would have to exit my IPython shell for bash to set the previous value. So I want termtitle to technically be a stack, on which I can push a title or pop-it without having to know what the previous one was. See for example https://github.com/ipython/ipython/issues/9722, which is recurrent. Without a getter (which is a security issue) or introducing global state or passing the values all around you can't set a temporary value for the title. Is that clearer ?

yes, it is. thank you ! one simple solution might be to wrap this thingy within an 'xprop(1)' invokation. for example, i can do the following:

    signal11@fatcat networking % xprop -id 0x2c00022 | grep WM_NAME
    WM_NAME(STRING) = "fatcat:~/source-code/c/networking"
    signal11@fatcat networking % cd ~/source-code/c/quick-hacks 
    signal11@fatcat quick-hacks % xprop -id 0x2c00022 | grep WM_NAME
    WM_NAME(STRING) = "fatcat:~/source-code/c/quick-hacks"
    signal11@fatcat quick-hacks % 

WM_NAME(STRING) points to the current title. and when i change the directory, i can query the new name. fitting this mechanism for aforementioned usecase is left as an exercise for the reader :) fwiw, the value for '-id' argument comes from 'xwininfo(1)'

That is a nice hack thanks! Though it is not really portable to all OS, and AFAIU not working if you ssh to a remote host ! It may give a potential way to work partially around that limitation. I feel like an actual push/pop solution would be better.

X being a network protocol at heart, it positively is weird. i tried that thingy on both local machine, and ssh'ed xterm to remote-machine (with X sessions correctly forwarded locally), and it all seems to work just fine for me.

edit-001 : these are linux machines at both ends, so, i dunno...

Yes, I'm on Mac OS so that's likely it, and the server I was trying had no X anyway. Thanks for investigating.
