Screws up terminal

[sevagh]

Hello,

I'm trying to use this in a crate where I have my own shell, and I want to output text and images side by side.

After calling write_ansi_truecolor once, an image successfully displays (and I can print more images), my terminal goes all wonky and writing to stdout/typing input from my keyboard does nothing until I type reset or exit the terminal.

Example:

writeln!(out, "Hello")
ops::write_ansi_truecolor(img1)
writeln!(out, "World")
ops::write_ansi_truecolor(img2)

=>

Hello
*img1*
*img2*
// can't type anymore

Any way to reset the terminal after outputting an image? Or any idea what's going on?

Thanks.

Same behavior observed in alacritty and gnome-terminal (with or without tmux).

any idea what

Nay, besides the fact that your term might not support ANSI truecolour escapes.

reset the terminal

I mean I don't use Linux much but reset probably works right

[sevagh]

Yeah, reset works. The termimage binary (cargo install termimage) has the same behavior, so it's not me incorrectly using the library. I'll do some poking around regarding truecolor support, thanks.

[nabijaczleweli]

Well I mean yeah the exec is just an iface to the library, it'd be weird if it didn't happen there. Oh and please do report back when you have some data about truecolourness.

So the image displays. Just mangles everything afterwards until I reset.

Define "mangles"?

[sevagh]

Everything I type subsequently, or that my program outputs to stdout, is hidden. Here I typed ls and enter a few times and it magically "recovered" (but my program exit):

I just checked with a friend and it works fine for him. Closing this as a bug with my own setup.

Thanks for the help, cool library!

Cheers, mate

Actually figured it out. Adding this helps:

ops::write_ansi_truecolor(out, &resized);
writeln!(out, "\x1b[0m").expect("Couldn't write to stdout");

\x1b[0m is Rust's equivalent of \033[0m.
