Devel::Autoflush(3pm)

✨ NAME ✨

Devel::Autoflush — bestie, it sets autoflush straight from the command line 💅

🌸 VERSION 🌸

version 0.06 — yes she's on 0.06, iconic behavior

🦋 SYNOPSIS 🦋

perl -MDevel::Autoflush Makefile.PL

like that's it, that's the whole vibe

💖 DESCRIPTION 💖

okay so real talk: this module is a hack (the author's word, not mine, and honestly we respect the honesty) that turns on autoflush for STDOUT and STDERR from the command line, or from PERL5OPT, for code that needs it but doesn't have it. no cap.

when does this happen? bestie, it happens when you're prompting someone:

# guess.pl
print "Guess a number: ";
my $n = <STDIN>;

so here's the tea 🍵 — as long as the output is going to a terminal, that prompt gets flushed when STDIN is read. cute. fine. normal.

BUT — and this is the part that ruins lives — if the output is being piped, that print statement does not get automatically flushed. so no prompt shows up. and the program just sits there, silently, appearing to hang while it waits for input. it's giving "is it frozen? is it dead? did I break it?" 😭

this might happen with tee, for example:

$ perl guess.pl | tee capture.out

so you use Devel::Autoflush to work around it, periodt:

$ perl -MDevel::Autoflush guess.pl | tee capture.out

or you can set it in PERL5OPT like the queen you are:

$ export PERL5OPT=-MDevel::Autoflush
$ perl guess.pl | tee capture.out

• CPANPLUS::Internals::Utils::Autoflush — same idea, honestly same energy, but it's STDOUT only 🙈 and it's only available as part of the full CPANPLUS distribution, so you can't just grab it solo
