Hi all,
after watching "DEF CON 31 - Terminally Owned - 60 Years of Escaping - David
Leadbeater" [1] I wrote this recipe to test our message behavior.
SUMMARY = "Test escape sequences"
DESCRIPTION = "Test escape sequences"
LICENSE = "MIT"
python do_compile() {
bb.plain("\033[31;1;4mHello\033[0m\n");
}
do_install() {
bbwarn "\033[31;1;4mHello\033[0m\n"
}
At least on my terminal it will print a red Hello with a newline.
Dmesg and sytemd both escape unprintable characters by default.
I propose that we should do the same.
We could still offer an option to just print those, for all people who want to
have shiny color outputs.
As a second step we could even try to escape them before writing them to the
logfile? This would help people who don't know about cat -v and so on?
What is your opinion about that?
Greets,
Bernhard
