text in text editors gets scrambled after defining set_prompt
I've set set_prompt to print prompt always on a new line.
set_prompt() {
local curpos
stty -echo
while read -t 0; do :; done
echo -en "33[6n"
IFS=';' read -s -d R -a curpos
stty echo
(( curpos[1] > 1 )) && printf "n"
}
but now, if I edit a file in text editors like emacs or nano, the text gets scrambled like printing character at wrong place or cursor jumps ahead or back while navigating, making text overlap.
at this point
PS1=[]$(git rev-parse --git-dir > /dev/null 2>&1 && git rev-parse --abbrev-ref HEAD 2>/dev/null || echo ${HOSTNAME})[]:[]W[] Necktwi[]$[]
PROMPT_COMMAND=set_prompt
Instead of setting the set_prompt, one can also do
PS1='$(printf "%$((COLUMNS-1))sr")'$PS1
but even this gives the glitch in emacs, not tested nano, but not as bad as the above. I was able to correct this much less scrambled text by deleting the generated spurious characters.

The purpose of the[and]are to contain non-printing characters. If there is nothing in between them, they are useless, so you can tidy up your PS1. You need to add them to the set_prompt funtion:echo -en "[33[6n]"

I am curious about the purpose of that function. Why do you have it?
