=head1 DESCRIPTION
Capture::Tiny provides a simple, portable way to capture almost anything sent
to STDOUT or STDERR, regardless of whether it comes from Perl, from XS code or
from an external program. Optionally, output can be teed so that it is
captured while being passed through to the original filehandles. Yes, it even
works on Windows (usually). Stop guessing which of a dozen capturing modules
to use in any particular situation and just use this one.
=head1 USAGE
The following functions are available. None are exported by default.
=head2 capture
($stdout, $stderr, @result) = capture \&code;
t/lib/Capture/Tiny.pm view on Meta::CPAN
Caution: STDOUT and STDERR output in the merged result are not guaranteed to be
properly ordered due to buffering.
=head2 tee
($stdout, $stderr, @result) = tee \&code;
$stdout = tee \&code;
The C<<< tee >>> function works just like C<<< capture >>>, except that output is captured
as well as passed on to the original STDOUT and STDERR.
When called in void context, C<<< tee >>> saves memory and time by
not reading back from the capture handles, except when the
original STDOUT OR STDERR were tied or opened to a scalar
handle.
=head2 tee_stdout
($stdout, @result) = tee_stdout \&code;
$stdout = tee_stdout \&code;
The C<<< tee_stdout >>> function works just like C<<< tee >>> except only
STDOUT is teed. STDERR is not teed (output goes to STDERR as usual).
t/lib/Capture/Tiny.pm view on Meta::CPAN
Note that this reopening will happen even for STDIN or a filehandle not being
captured to ensure that the filehandle used for capture is not opened to file
descriptor 0, as this causes problems on various platforms.
Prior to Perl 5.12, closed STDIN combined with PERL_UNICODE=D leaks filehandles
and also breaks tee() for undiagnosed reasons. So don't do that.
B<Localized filehandles>
If code localizes any of Perl's standard filehandles before capturing, the capture
will affect the localized filehandles and not the original ones. External system
calls are not affected by localizing a filehandle in Perl and will continue
to send output to the original filehandles (which will thus not be captured).
B<Scalar filehandles>
If STDOUT or STDERR are reopened to scalar filehandles prior to the call to
C<<< capture >>> or C<<< tee >>>, then Capture::Tiny will override the output filehandle for
the duration of the C<<< capture >>> or C<<< tee >>> call and then, for C<<< tee >>>, send captured
output to the output filehandle after the capture is complete. (Requires Perl
5.8)
Capture::Tiny attempts to preserve the semantics of STDIN opened to a scalar
