=head1 DESCRIPTION

Capture::Tiny provides a simple, portable way to capture almost anything sent

t/lib/Capture/Tiny.pm  view on Meta::CPAN

The following functions are available.  None are exported by default.

=head2 capture

   ($stdout, $stderr, @result) = capture \&code;
   $stdout = capture \&code;

The C<<< capture >>> function takes a code reference and returns what is sent to
STDOUT and STDERR as well as any return values from the code reference.  In
scalar context, it returns only STDOUT.  If no output was received for a

t/lib/Capture/Tiny.pm  view on Meta::CPAN

context, all output is captured -- nothing is passed to the existing filehandles.

It is prototyped to take a subroutine reference as an argument. Thus, it
can be called in block form:

   ($stdout, $stderr) = capture {
     # your code here ...
   };

Note that the coderef is evaluated in list context.  If you wish to force
scalar context on the return value, you must use the C<<< scalar >>> keyword.

   ($stdout, $stderr, $count) = capture {
     my @list = qw/one two three/;
     return scalar @list; # $count will be 3
   };

Also note that within the coderef, the C<<< @_ >>> variable will be empty.  So don't
use arguments from a surrounding subroutine without copying them to an array
first:

   sub wont_work {
     my ($stdout, $stderr) = capture { do_stuff( @_ ) };    # WRONG
     ...
   }
 
   sub will_work {
     my @args = @_;
     my ($stdout, $stderr) = capture { do_stuff( @args ) }; # RIGHT
     ...
   }

Captures are normally done to an anonymous temporary filehandle.  To
capture via a named file (e.g. to externally monitor a long-running capture),
provide custom filehandles as a trailing list of option pairs:

   my $out_fh = IO::File->new("out.txt", "w+");
   my $err_fh = IO::File->new("out.txt", "w+");
   capture { ... } stdout => $out_fh, stderr => $err_fh;

The filehandles must be readE<sol>write and seekable.  Modifying the files or
filehandles during a capture operation will give unpredictable results.
Existing IO layers on them may be changed by the capture.

t/lib/Capture/Tiny.pm  view on Meta::CPAN

   $stdout = capture_stdout \&code;

The C<<< capture_stdout >>> function works just like C<<< capture >>> except only
STDOUT is captured.  STDERR is not captured.

=head2 capture_stderr

   ($stderr, @result) = capture_stderr \&code;
   $stderr = capture_stderr \&code;

The C<<< capture_stderr >>> function works just like C<<< capture >>> except only
STDERR is captured.  STDOUT is not captured.

=head2 capture_merged

   ($merged, @result) = capture_merged \&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.

t/lib/Capture/Tiny.pm  view on Meta::CPAN

   $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).

=head2 tee_stderr

   ($stderr, @result) = tee_stderr \&code;
   $stderr = tee_stderr \&code;

The C<<< tee_stderr >>> function works just like C<<< tee >>> except only
STDERR is teed.  STDOUT is not teed (output goes to STDOUT as usual).

=head2 tee_merged

   ($merged, @result) = tee_merged \&code;
