[Message part 1 (text/plain, inline)]

Hi,

Whenever I run `guix environment <package>`, the shell I get has
problems when I write commands that span multiple lines. The most basic
glitch is that when I get to the end of the first line, the next
characters end up at the beginning of the same line, overwriting
everything I wrote so far. One of the wilder scenarios is the one where
each new character is added on a new line, _on top_ of the one I'm
currently writing.

Steps to reproduce:
1. $ guix environment neovim
2. Write stuff that is longer than a single line.

I attached a screenshot for the first situation. You can see how the
text has overwritten my prompt.

Cheers,

What shell do you use?

Could you check if this is somehow due to PS1?  For instance run:

  guix environment neovim
  export PS1='\u\$ '
  write a loooong line

Thanks in advance,
Ludo’.

That fixed it, so it isn't a Guix bug. Thanks a lot!

It was something wrong with how I set the colors with tput that only
manifested when I entered an environment cause that appends a colored
"[env]" to my PS1.
