Thank you for your clarification and updates.

Can you create a more detailed issue with your thoughts and explaining what you expect when reading the terminal state? I confess I'm still figuring out the interactions between terminfo, tput, tcgetattr, etc. but given what I understand, I'll probably come across the state reading issue soon (I'm developing a project that incorporates something similar to fzf) and I would love to contribute with a PR then :)

Yes, you can close the current issue.

I added a longer description in #4. Feel free to comment there if you are interested.
Regarding your project -- sounds interesting and like it could benefit both you and tput.cr
. Feel free to open tickets for any discussion or help you'd need from me. Thanks!

I tried a variant without the listen() loop that works perfectly. Same thing with break
instead of exit
.
It seems that exiting from the listen loop creates the terminal state corruption (maybe because of a raw mode access to the terminal for reading events ?)

Heya, let me check and I will report back shortly.

Hey,
Yes, you are right, break
helps a lot because it properly ends the with_raw_input
block which returns the terminal mode back to what it was. So that solves the first part of the issue.
The second part is that even after mode is restored, cursor color remains red, and not even reset
helps. Obviously that's because reset
doesn't touch the cursor itself. Unfortunately tput.cr
currently does not support any escape sequences that read data from the terminal -- including the one which reads the complete terminal state.
(I am referring to some equivalent of function _bindResponse
in Blessed's file https://github.com/chjj/blessed/blob/master/lib/program.js , on line 1040).
(I would be very much interested in receiving a PR that adds this; that would be amazing!)
In any case, because of inability to read terminal state, it is not possible to return the cursor color and blink to what it was before running the program; what we can do is just assume that the color before was white, and set it to white.
I've updated the README example to show this, and to fix some other things -- for example, terminal type and features were printed at the top of example, but weren't visible on screen because after print the screen was switched to alternate buffer. And I've made a number of smaller clarifications/improvements in code comments.
Hope it helps and thanks for the report!
Feel free to continue the discussion, or close the ticket if your question was adequately covered.
