NAME

       Devel::Autoflush - Set autoflush from the command line

VERSION

       version 0.06

SYNOPSIS

        perl -MDevel::Autoflush Makefile.PL

DESCRIPTION

       This module is a hack to set autoflush for STDOUT and STDERR from the command line or from
       "PERL5OPT" for code that needs it but doesn't have it.

       This often happens when prompting:

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

       As long as the output is going to a terminal, the prompt is flushed when STDIN is read.
       However, if the output is being piped, the print statement will not automatically be
       flushed, no prompt will be seen and the program will silently appear to hang while waiting
       for input.  This might happen with 'tee':

         $ perl guess.pl | tee capture.out

       Use Devel::Autoflush to work around this:

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

       Or set it in "PERL5OPT":

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

       •   CPANPLUS::Internals::Utils::Autoflush -- same idea but STDOUT only and

           only available as part of the full CPANPLUS distribution
