[Discussion] support for SIGWINCH?

[huijunchen9260]

Dear all:

This is a discussion thread for possible support for SIGWINCH, which makes the TUI response to the change of the font size of the terminal.

I've tried the following script with no luck:

awk '
BEGIN{
srand()
system("stty -isig -icanon -echo")
printf "\033\1332J\033\133H" >> "/dev/stderr" # clear screen
printf "\033\133?1049h" >> "/dev/stderr" # alternate buffer
printf "\033\1337" >> "/dev/stderr" # save cursor
printf "\033\133?25l" >> "/dev/stderr" # hide cursor
printf "\033\133?7l" >> "/dev/stderr" # line wrap
while (1) {
    system("trap \"echo \"YES\"\"; WINCH")
    system("sleep 1")
}
printf "\033\1332J\033\133H" >> "/dev/stderr" # clear screen
printf "\033\133?7h" >> "/dev/stderr" # line wrap
printf "\033\1338" >> "/dev/stderr" # restore cursor
printf "\033\133?25h" >> "/dev/stderr" # hide cursor
printf "\033\133?1049l" >> "/dev/stderr" # back from alternate buffer
system("stty isig icanon echo")

}'
