This file contains instructions that will help you work with the source code. The distribution is managed with Dist::Zilla. This means than many of the usual files you might expect are not in the repository, but are generated at release time, as is much of the documentation. Some generated files are kept in the repository as a convenience (e.g. Makefile.PL or cpanfile). Generally, **you do not need Dist::Zilla to contribute patches**. You do need Dist::Zilla to create a tarball. See below for guidance. ### Getting dependencies If you have App::cpanminus 1.6 or later installed, you can use `cpanm` to satisfy dependencies like this: $ cpanm --installdeps . Otherwise, look for either a `Makefile.PL` or `cpanfile` file for a list of dependencies to satisfy. ### Running tests You can run tests directly using the `prove` tool: $ prove -l $ prove -lv t/some_test_file.t For most of my distributions, `prove` is entirely sufficient for you to test any patches you have. I use `prove` for 99% of my testing during development. ### Code style and tidying Please try to match any existing coding style. If there is a `.perltidyrc` file, please install Perl::Tidy and use perltidy before submitting patches. If there is a `tidyall.ini` file, you can also install Code::TidyAll and run `tidyall` on a file or `tidyall -a` to tidy all files. ### Patching documentation Much of the documentation Pod is generated at release time. Some is generated boilerplate; other documentation is built from pseudo-POD directives in the source like C<=method> or C<=func>. If you would like to submit a documentation edit, please limit yourself to the documentation you see. If you see typos or documentation issues in the generated docs, please email or open a bug ticket instead of patching. ### Installing and using Dist::Zilla Dist::Zilla is a very powerful authoring tool, optimized for maintaining a large number of distributions with a high degree of automation, but it has a large dependency chain, a bit of a learning curve and requires a number of author-specific plugins. To install it from CPAN, I recommend one of the following approaches for the quickest installation: # using CPAN.pm, but bypassing non-functional pod tests $ cpan TAP::Harness::Restricted $ PERL_MM_USE_DEFAULT=1 HARNESS_CLASS=TAP::Harness::Restricted cpan Dist::Zilla # using cpanm, bypassing *all* tests $ cpanm -n Dist::Zilla In either case, it's probably going to take about 10 minutes. Go for a walk, go get a cup of your favorite beverage, take a bathroom break, or whatever. When you get back, Dist::Zilla should be ready for you. Then you need to install any plugins specific to this distribution: $ cpan `dzil authordeps` $ dzil authordeps | cpanm Once installed, here are some dzil commands you might try: $ dzil build $ dzil test $ dzil xtest You can learn more about Dist::Zilla at http://dzil.org/ PK ��[ pm_to_blibnu �[��� PK ��[ O/6' 6' Changesnu �[��� Revision history for Capture-Tiny 0.48 2018-04-22 09:01:08+02:00 Europe/Oslo - No changes from 0.47-TRIAL 0.47 2017-07-26 10:34:24-04:00 America/New_York (TRIAL RELEASE) [Fixed] - Appends PID to random file names for tee signalling to avoid random name collision when used in multiple forked children. 0.46 2017-02-25 14:19:22-05:00 America/New_York - No changes from 0.45-TRIAL 0.45 2017-02-23 13:22:43-05:00 America/New_York (TRIAL RELEASE) [Internal] - Avoid variable shadowing to improve debuggability. 0.44 2016-08-05 13:40:33-04:00 America/New_York [Docs] - Note that dropping privileges during a capture can lead to temporary files not cleaned up. 0.42 2016-05-31 12:40:10-04:00 America/New_York - No changes from 0.41 0.41 2016-05-23 11:58:15-04:00 America/New_York (TRIAL RELEASE) [Fixed] - Fixed some failing tests when STDIN is routed to /dev/null 0.40 2016-05-23 11:42:35-04:00 America/New_York - No changes from 0.39 0.39 2016-05-02 10:21:48-04:00 America/New_York (TRIAL RELEASE) [Fixed] - Fix in 0.37 tickled a very obscure regular expressions bug in perl < 5.18; should now be fixed. 0.37 2016-05-02 07:08:31-04:00 America/New_York (TRIAL RELEASE) [Fixed] - Skip some tests if locale can't be determined. 0.36 2016-02-28 21:36:57-05:00 America/New_York [Docs] - Fixed typos. 0.34 2016-02-18 23:26:13-05:00 America/New_York [Fixed] - Removed spurious JSON::PP dependency added by a broken Dist::Zilla plugin. 0.32 2016-02-18 10:12:02-05:00 America/New_York [Docs] - Changed internal formatting of documentation [Changes] - No functional changes from 0.31 0.31 2016-02-14 07:33:50-07:00 America/Mazatlan (TRIAL RELEASE) [Fixed] - Application of layers to handles during and after capture now attempts to more accurately duplicate the original layers, including potential duplicate layers.

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. .SH "USAGE" .IX Header "USAGE" The following functions are available. None are exported by default. .SS "capture" .IX Subsection "capture" .Vb 2 \& ($stdout, $stderr, @result) = capture \e&code; \& $stdout = capture \e&code; .Ve .PP The \f(CW\*(C`capture\*(C'\fR function takes a code reference and returns what is sent to \&\s-1STDOUT\s0 and \s-1STDERR\s0 as well as any return values from the code reference. In scalar context, it returns only \s-1STDOUT.\s0 If no output was received for a filehandle, it returns an empty string for that filehandle. Regardless of calling context, all output is captured \*(-- nothing is passed to the existing filehandles. .PP It is prototyped to take a subroutine reference as an argument. Thus, it can be called in block form: .PP .Vb 3 \& ($stdout, $stderr) = capture { \& # your code here ... \& }; .Ve .PP Note that the coderef is evaluated in list context. If you wish to force scalar context on the return value, you must use the \f(CW\*(C`scalar\*(C'\fR keyword. .PP .Vb 4 \& ($stdout, $stderr, $count) = capture { \& my @list = qw/one two three/; \& return scalar @list; # $count will be 3 \& }; .Ve .PP Also note that within the coderef, the \f(CW@_\fR variable will be empty. So don't use arguments from a surrounding subroutine without copying them to an array first: .PP .Vb 4 \& sub wont_work { \& my ($stdout, $stderr) = capture { do_stuff( @_ ) }; # WRONG \& ... \& } \& \& sub will_work { \& my @args = @_; \& my ($stdout, $stderr) = capture { do_stuff( @args ) }; # RIGHT \& ... \& } .Ve .PP 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: .PP .Vb 3 \& my $out_fh = IO::File\->new("out.txt", "w+"); \& my $err_fh = IO::File\->new("out.txt", "w+"); \& capture { ... } stdout => $out_fh, stderr => $err_fh; .Ve .PP The filehandles must be read/write and seekable. Modifying the files or filehandles during a capture operation will give unpredictable results. Existing \s-1IO\s0 layers on them may be changed by the capture. .PP When called in void context, \f(CW\*(C`capture\*(C'\fR saves memory and time by not reading back from the capture handles. .SS "capture_stdout" .IX Subsection "capture_stdout" .Vb 2 \& ($stdout, @result) = capture_stdout \e&code; \& $stdout = capture_stdout \e&code; .Ve .PP The \f(CW\*(C`capture_stdout\*(C'\fR function works just like \f(CW\*(C`capture\*(C'\fR except only \&\s-1STDOUT\s0 is captured. \s-1STDERR\s0 is not captured. .SS "capture_stderr" .IX Subsection "capture_stderr" .Vb 2 \& ($stderr, @result) = capture_stderr \e&code; \& $stderr = capture_stderr \e&code; .Ve .PP The \f(CW\*(C`capture_stderr\*(C'\fR function works just like \f(CW\*(C`capture\*(C'\fR except only \&\s-1STDERR\s0 is captured. \s-1STDOUT\s0 is not captured. .SS "capture_merged" .IX Subsection "capture_merged" .Vb 2 \& ($merged, @result) = capture_merged \e&code; \& $merged = capture_merged \e&code; .Ve .PP The \f(CW\*(C`capture_merged\*(C'\fR function works just like \f(CW\*(C`capture\*(C'\fR except \s-1STDOUT\s0 and \&\s-1STDERR\s0 are merged. (Technically, \s-1STDERR\s0 is redirected to the same capturing handle as \s-1STDOUT\s0 before executing the function.) .PP Caution: \s-1STDOUT\s0 and \s-1STDERR\s0 output in the merged result are not guaranteed to be properly ordered due to buffering. .SS "tee" .IX Subsection "tee" .Vb 2 \& ($stdout, $stderr, @result) = tee \e&code; \& $stdout = tee \e&code; .Ve .PP The \f(CW\*(C`tee\*(C'\fR function works just like \f(CW\*(C`capture\*(C'\fR, except that output is captured as well as passed on to the original \s-1STDOUT\s0 and \s-1STDERR.\s0 .PP When called in void context, \f(CW\*(C`tee\*(C'\fR saves memory and time by not reading back from the capture handles, except when the original \s-1STDOUT OR STDERR\s0 were tied or opened to a scalar handle. .SS "tee_stdout" .IX Subsection "tee_stdout" .Vb 2 \& ($stdout, @result) = tee_stdout \e&code; \& $stdout = tee_stdout \e&code; .Ve .PP The \f(CW\*(C`tee_stdout\*(C'\fR function works just like \f(CW\*(C`tee\*(C'\fR except only \&\s-1STDOUT\s0 is teed. \s-1STDERR\s0 is not teed (output goes to \s-1STDERR\s0 as usual). .SS "tee_stderr" .IX Subsection "tee_stderr" .Vb 2 \& ($stderr, @result) = tee_stderr \e&code; \& $stderr = tee_stderr \e&code; .Ve .PP The \f(CW\*(C`tee_stderr\*(C'\fR function works just like \f(CW\*(C`tee\*(C'\fR except only \&\s-1STDERR\s0 is teed. \s-1STDOUT\s0 is not teed (output goes to \s-1STDOUT\s0 as usual). .SS "tee_merged" .IX Subsection "tee_merged" .Vb 2 \& ($merged, @result) = tee_merged \e&code; \& $merged = tee_merged \e&code; .Ve .PP The \f(CW\*(C`tee_merged\*(C'\fR function works just like \f(CW\*(C`capture_merged\*(C'\fR except that output is captured as well as passed on to \s-1STDOUT.\s0 .PP Caution: \s-1STDOUT\s0 and \s-1STDERR\s0 output in the merged result are not guaranteed to be properly ordered due to buffering. .SH "LIMITATIONS" .IX Header "LIMITATIONS" .SS "Portability" .IX Subsection "Portability" Portability is a goal, not a guarantee. \f(CW\*(C`tee\*(C'\fR requires fork, except on Windows where \f(CW\*(C`system(1, @cmd)\*(C'\fR is used instead. Not tested on any particularly esoteric platforms yet. See the \&\s-1CPAN\s0 Testers Matrix <http://matrix.cpantesters.org/?dist=Capture-Tiny> for test result by platform. .SS "PerlIO layers" .IX Subsection "PerlIO layers" Capture::Tiny does its best to preserve PerlIO layers such as ':utf8' or \&':crlf' when capturing (only for Perl 5.8.1+) . Layers should be applied to \&\s-1STDOUT\s0 or \s-1STDERR\s0 \fIbefore\fR the call to \f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR. This may not work for tied filehandles (see below). .SS "Modifying filehandles before capturing" .IX Subsection "Modifying filehandles before capturing" Generally speaking, you should do little or no manipulation of the standard \s-1IO\s0 filehandles prior to using Capture::Tiny. In particular, closing, reopening, localizing or tying standard filehandles prior to capture may cause a variety of unexpected, undesirable and/or unreliable behaviors, as described below. Capture::Tiny does its best to compensate for these situations, but the results may not be what you desire. .PP \fIClosed filehandles\fR .IX Subsection "Closed filehandles" .PP Capture::Tiny will work even if \s-1STDIN, STDOUT\s0 or \s-1STDERR\s0 have been previously closed. However, since they will be reopened to capture or tee output, any code within the captured block that depends on finding them closed will, of course, not find them to be closed. If they started closed, Capture::Tiny will close them again when the capture block finishes. .PP Note that this reopening will happen even for \s-1STDIN\s0 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. .PP Prior to Perl 5.12, closed \s-1STDIN\s0 combined with PERL_UNICODE=D leaks filehandles and also breaks \fBtee()\fR for undiagnosed reasons. So don't do that. .PP \fILocalized filehandles\fR .IX Subsection "Localized filehandles" .PP 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). .PP \fIScalar filehandles\fR .IX Subsection "Scalar filehandles" .PP If \s-1STDOUT\s0 or \s-1STDERR\s0 are reopened to scalar filehandles prior to the call to \&\f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR, then Capture::Tiny will override the output filehandle for the duration of the \f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR call and then, for \f(CW\*(C`tee\*(C'\fR, send captured output to the output filehandle after the capture is complete. (Requires Perl 5.8) .PP Capture::Tiny attempts to preserve the semantics of \s-1STDIN\s0 opened to a scalar reference, but note that external processes will not be able to read from such a handle. Capture::Tiny tries to ensure that external processes will read from the null device instead, but this is not guaranteed. .PP \fITied output filehandles\fR .IX Subsection "Tied output filehandles" .PP If \s-1STDOUT\s0 or \s-1STDERR\s0 are tied prior to the call to \f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR, then Capture::Tiny will attempt to override the tie for the duration of the \&\f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR call and then send captured output to the tied filehandle after the capture is complete. (Requires Perl 5.8) .PP Capture::Tiny may not succeed resending \s-1UTF\-8\s0 encoded data to a tied \&\s-1STDOUT\s0 or \s-1STDERR\s0 filehandle. Characters may appear as bytes. If the tied filehandle is based on Tie::StdHandle, then Capture::Tiny will attempt to determine appropriate layers like \f(CW\*(C`:utf8\*(C'\fR from the underlying filehandle and do the right thing. .PP \fITied input filehandle\fR .IX Subsection "Tied input filehandle" .PP Capture::Tiny attempts to preserve the semantics of tied \s-1STDIN,\s0 but this requires Perl 5.8 and is not entirely predictable. External processes will not be able to read from such a handle. .PP Unless having \s-1STDIN\s0 tied is crucial, it may be safest to localize \s-1STDIN\s0 when capturing: .PP .Vb 1 \& my ($out, $err) = do { local *STDIN; capture { ... } }; .Ve .SS "Modifying filehandles during a capture" .IX Subsection "Modifying filehandles during a capture" Attempting to modify \s-1STDIN, STDOUT\s0 or \s-1STDERR\s0 \fIduring\fR \f(CW\*(C`capture\*(C'\fR or \f(CW\*(C`tee\*(C'\fR is almost certainly going to cause problems. Don't do that. .PP \fIForking inside a capture\fR .IX Subsection "Forking inside a capture" .PP Forks aren't portable. The behavior of filehandles during a fork is even less so. If Capture::Tiny detects that a fork has occurred within a capture, it will shortcut in the child process and return empty strings for captures. Other problems may occur in the child or parent, as well. Forking in a capture block is not recommended. .PP \fIUsing threads\fR .IX Subsection "Using threads" .PP Filehandles are global. Mixing up I/O and captures in different threads without coordination is going to cause problems. Besides, threads are officially discouraged. .PP \fIDropping privileges during a capture\fR .IX Subsection "Dropping privileges during a capture" .PP If you drop privileges during a capture, temporary files created to facilitate the capture may not be cleaned up afterwards. .SS "No support for Perl 5.8.0" .IX Subsection "No support for Perl 5.8.0" It's just too buggy when it comes to layers and \s-1UTF\-8.\s0 Perl 5.8.1 or later is recommended. .SS "Limited support for Perl 5.6" .IX Subsection "Limited support for Perl 5.6" Perl 5.6 predates PerlIO. \s-1UTF\-8\s0 data may not be captured correctly. .SH "ENVIRONMENT" .IX Header "ENVIRONMENT" .SS "\s-1PERL_CAPTURE_TINY_TIMEOUT\s0" .IX Subsection "PERL_CAPTURE_TINY_TIMEOUT" Capture::Tiny uses subprocesses internally for \f(CW\*(C`tee\*(C'\fR. By default, Capture::Tiny will timeout with an error if such subprocesses are not ready to receive data within 30 seconds (or whatever is the value of \&\f(CW$Capture::Tiny::TIMEOUT\fR). An alternate timeout may be specified by setting the \f(CW\*(C`PERL_CAPTURE_TINY_TIMEOUT\*(C'\fR environment variable. Setting it to zero will disable timeouts. \fB\s-1NOTE\s0\fR, this does not timeout the code reference being captured \*(-- this only prevents Capture::Tiny itself from hanging your process waiting for its child processes to be ready to proceed. .SH "SEE ALSO" .IX Header "SEE ALSO" This module was inspired by IO::CaptureOutput, which provides similar functionality without the ability to tee output and with more complicated code and \s-1API.\s0 IO::CaptureOutput does not handle layers or most of the unusual cases described in the \*(L"Limitations\*(R" section and I no longer recommend it. .PP There are many other \s-1CPAN\s0 modules that provide some sort of output capture, albeit with various limitations that make them appropriate only in particular circumstances. I'm probably missing some. The long list is provided to show why I felt Capture::Tiny was necessary. .IP "\(bu" 4 IO::Capture .IP "\(bu" 4 IO::Capture::Extended .IP "\(bu" 4 IO::CaptureOutput .IP "\(bu" 4 IPC::Capture .IP "\(bu" 4 IPC::Cmd .IP "\(bu" 4 IPC::Open2 .IP "\(bu" 4 IPC::Open3 .IP "\(bu" 4 IPC::Open3::Simple .IP "\(bu" 4 IPC::Open3::Utils .IP "\(bu" 4 IPC::Run .IP "\(bu" 4 IPC::Run::SafeHandles .IP "\(bu" 4 IPC::Run::Simple .IP "\(bu" 4 IPC::Run3 .IP "\(bu" 4 IPC::System::Simple .IP "\(bu" 4 Tee .IP "\(bu" 4 IO::Tee .IP "\(bu" 4 File::Tee .IP "\(bu" 4 Filter::Handle .IP "\(bu" 4 Tie::STDERR .IP "\(bu" 4 Tie::STDOUT .IP "\(bu" 4 Test::Output .SH "SUPPORT" .IX Header "SUPPORT" .SS "Bugs / Feature Requests" .IX Subsection "Bugs / Feature Requests" Please report any bugs or feature requests through the issue tracker at <https://github.com/dagolden/Capture\-Tiny/issues>.

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; $stdout = capture \&code; The C<capture> function takes a code reference and returns what is sent to STDOUT and STDERR as well as any return values from the code reference. In scalar context, it returns only STDOUT. If no output was received for a filehandle, it returns an empty string for that filehandle. Regardless of calling context, all output is captured -- nothing is passed to the existing filehandles. It is prototyped to take a subroutine reference as an argument. Thus, it can be called in block form: ($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 => $err_fh; The filehandles must be read/write and seekable. Modifying the files or filehandles during a capture operation will give unpredictable results. Existing IO layers on them may be changed by the capture. When called in void context, C<capture> saves memory and time by not reading back from the capture handles. =head2 capture_stdout ($stdout, @result) = capture_stdout \&code; $stdout = capture_stdout \&code; The C<capture_stdout> function works just like C<capture> except only STDOUT is captured. STDERR is not captured. =head2 capture_stderr ($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; $merged = capture_merged \&code; The C<capture_merged> function works just like C<capture> except STDOUT and STDERR are merged. (Technically, STDERR is redirected to the same capturing handle as STDOUT before executing the function.) Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. =head2 tee ($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; $stdout = tee_stdout \&code; The C<tee_stdout> function works just like C<tee> except only STDOUT is teed. STDERR is not teed (output goes to STDERR as usual). =head2 tee_stderr ($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; $merged = tee_merged \&code; The C<tee_merged> function works just like C<capture_merged> except that output is captured as well as passed on to STDOUT. Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. =head1 LIMITATIONS =head2 Portability Portability is a goal, not a guarantee. C<tee> requires fork, except on Windows where C<system(1, @cmd)> is used instead. Not tested on any particularly esoteric platforms yet. See the L<CPAN Testers Matrix|http://matrix.cpantesters.org/?dist=Capture-Tiny> for test result by platform. =head2 PerlIO layers Capture::Tiny does its best to preserve PerlIO layers such as ':utf8' or ':crlf' when capturing (only for Perl 5.8.1+) . Layers should be applied to STDOUT or STDERR I<before> the call to C<capture> or C<tee>. This may not work for tied filehandles (see below). =head2 Modifying filehandles before capturing Generally speaking, you should do little or no manipulation of the standard IO filehandles prior to using Capture::Tiny. In particular, closing, reopening, localizing or tying standard filehandles prior to capture may cause a variety of unexpected, undesirable and/or unreliable behaviors, as described below. Capture::Tiny does its best to compensate for these situations, but the results may not be what you desire. =head3 Closed filehandles Capture::Tiny will work even if STDIN, STDOUT or STDERR have been previously closed. However, since they will be reopened to capture or tee output, any code within the captured block that depends on finding them closed will, of course, not find them to be closed. If they started closed, Capture::Tiny will close them again when the capture block finishes. 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. =head3 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). =head3 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 reference, but note that external processes will not be able to read from such a handle. Capture::Tiny tries to ensure that external processes will read from the null device instead, but this is not guaranteed. =head3 Tied output filehandles If STDOUT or STDERR are tied prior to the call to C<capture> or C<tee>, then Capture::Tiny will attempt to override the tie for the duration of the C<capture> or C<tee> call and then send captured output to the tied filehandle after the capture is complete. (Requires Perl 5.8) Capture::Tiny may not succeed resending UTF-8 encoded data to a tied STDOUT or STDERR filehandle. Characters may appear as bytes. If the tied filehandle is based on L<Tie::StdHandle>, then Capture::Tiny will attempt to determine appropriate layers like C<:utf8> from the underlying filehandle and do the right thing. =head3 Tied input filehandle Capture::Tiny attempts to preserve the semantics of tied STDIN, but this requires Perl 5.8 and is not entirely predictable. External processes will not be able to read from such a handle. Unless having STDIN tied is crucial, it may be safest to localize STDIN when capturing: my ($out, $err) = do { local *STDIN; capture { ... } }; =head2 Modifying filehandles during a capture Attempting to modify STDIN, STDOUT or STDERR I<during> C<capture> or C<tee> is almost certainly going to cause problems. Don't do that. =head3 Forking inside a capture Forks aren't portable. The behavior of filehandles during a fork is even less so. If Capture::Tiny detects that a fork has occurred within a capture, it will shortcut in the child process and return empty strings for captures. Other problems may occur in the child or parent, as well. Forking in a capture block is not recommended. =head3 Using threads Filehandles are global. Mixing up I/O and captures in different threads without coordination is going to cause problems. Besides, threads are officially discouraged. =head3 Dropping privileges during a capture If you drop privileges during a capture, temporary files created to facilitate the capture may not be cleaned up afterwards. =head2 No support for Perl 5.8.0 It's just too buggy when it comes to layers and UTF-8. Perl 5.8.1 or later is recommended. =head2 Limited support for Perl 5.6 Perl 5.6 predates PerlIO. UTF-8 data may not be captured correctly. =head1 ENVIRONMENT =head2 PERL_CAPTURE_TINY_TIMEOUT Capture::Tiny uses subprocesses internally for C<tee>. By default, Capture::Tiny will timeout with an error if such subprocesses are not ready to receive data within 30 seconds (or whatever is the value of C<$Capture::Tiny::TIMEOUT>). An alternate timeout may be specified by setting the C<PERL_CAPTURE_TINY_TIMEOUT> environment variable. Setting it to zero will disable timeouts. B<NOTE>, this does not timeout the code reference being captured -- this only prevents Capture::Tiny itself from hanging your process waiting for its child processes to be ready to proceed. =head1 SEE ALSO This module was inspired by L<IO::CaptureOutput>, which provides similar functionality without the ability to tee output and with more complicated code and API. L<IO::CaptureOutput> does not handle layers or most of the unusual cases described in the L</Limitations> section and I no longer recommend it. There are many other CPAN modules that provide some sort of output capture, albeit with various limitations that make them appropriate only in particular circumstances. I'm probably missing some. The long list is provided to show why I felt Capture::Tiny was necessary. =over 4 =item * L<IO::Capture> =item * L<IO::Capture::Extended> =item * L<IO::CaptureOutput> =item * L<IPC::Capture> =item * L<IPC::Cmd> =item * L<IPC::Open2> =item * L<IPC::Open3> =item * L<IPC::Open3::Simple> =item * L<IPC::Open3::Utils> =item * L<IPC::Run> =item * L<IPC::Run::SafeHandles> =item * L<IPC::Run::Simple> =item * L<IPC::Run3> =item * L<IPC::System::Simple> =item * L<Tee> =item * L<IO::Tee> =item * L<File::Tee> =item * L<Filter::Handle> =item * L<Tie::STDERR> =item * L<Tie::STDOUT> =item * L<Test::Output> =back =for :stopwords cpan testmatrix url annocpan anno bugtracker rt cpants kwalitee diff irc mailto metadata placeholders metacpan =head1 SUPPORT =head2 Bugs / Feature Requests Please report any bugs or feature requests through the issue tracker at L<https://github.com/dagolden/Capture-Tiny/issues>.

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; $stdout = capture \&code; The C<capture> function takes a code reference and returns what is sent to STDOUT and STDERR as well as any return values from the code reference. In scalar context, it returns only STDOUT. If no output was received for a filehandle, it returns an empty string for that filehandle. Regardless of calling context, all output is captured -- nothing is passed to the existing filehandles. It is prototyped to take a subroutine reference as an argument. Thus, it can be called in block form: ($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 => $err_fh; The filehandles must be read/write and seekable. Modifying the files or filehandles during a capture operation will give unpredictable results. Existing IO layers on them may be changed by the capture. When called in void context, C<capture> saves memory and time by not reading back from the capture handles. =head2 capture_stdout ($stdout, @result) = capture_stdout \&code; $stdout = capture_stdout \&code; The C<capture_stdout> function works just like C<capture> except only STDOUT is captured. STDERR is not captured. =head2 capture_stderr ($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; $merged = capture_merged \&code; The C<capture_merged> function works just like C<capture> except STDOUT and STDERR are merged. (Technically, STDERR is redirected to the same capturing handle as STDOUT before executing the function.) Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. =head2 tee ($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; $stdout = tee_stdout \&code; The C<tee_stdout> function works just like C<tee> except only STDOUT is teed. STDERR is not teed (output goes to STDERR as usual). =head2 tee_stderr ($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; $merged = tee_merged \&code; The C<tee_merged> function works just like C<capture_merged> except that output is captured as well as passed on to STDOUT. Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. =head1 LIMITATIONS =head2 Portability Portability is a goal, not a guarantee. C<tee> requires fork, except on Windows where C<system(1, @cmd)> is used instead. Not tested on any particularly esoteric platforms yet. See the L<CPAN Testers Matrix|http://matrix.cpantesters.org/?dist=Capture-Tiny> for test result by platform. =head2 PerlIO layers Capture::Tiny does its best to preserve PerlIO layers such as ':utf8' or ':crlf' when capturing (only for Perl 5.8.1+) . Layers should be applied to STDOUT or STDERR I<before> the call to C<capture> or C<tee>. This may not work for tied filehandles (see below). =head2 Modifying filehandles before capturing Generally speaking, you should do little or no manipulation of the standard IO filehandles prior to using Capture::Tiny. In particular, closing, reopening, localizing or tying standard filehandles prior to capture may cause a variety of unexpected, undesirable and/or unreliable behaviors, as described below. Capture::Tiny does its best to compensate for these situations, but the results may not be what you desire. =head3 Closed filehandles Capture::Tiny will work even if STDIN, STDOUT or STDERR have been previously closed. However, since they will be reopened to capture or tee output, any code within the captured block that depends on finding them closed will, of course, not find them to be closed. If they started closed, Capture::Tiny will close them again when the capture block finishes. 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. =head3 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). =head3 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 reference, but note that external processes will not be able to read from such a handle. Capture::Tiny tries to ensure that external processes will read from the null device instead, but this is not guaranteed. =head3 Tied output filehandles If STDOUT or STDERR are tied prior to the call to C<capture> or C<tee>, then Capture::Tiny will attempt to override the tie for the duration of the C<capture> or C<tee> call and then send captured output to the tied filehandle after the capture is complete. (Requires Perl 5.8) Capture::Tiny may not succeed resending UTF-8 encoded data to a tied STDOUT or STDERR filehandle. Characters may appear as bytes. If the tied filehandle is based on L<Tie::StdHandle>, then Capture::Tiny will attempt to determine appropriate layers like C<:utf8> from the underlying filehandle and do the right thing. =head3 Tied input filehandle Capture::Tiny attempts to preserve the semantics of tied STDIN, but this requires Perl 5.8 and is not entirely predictable. External processes will not be able to read from such a handle. Unless having STDIN tied is crucial, it may be safest to localize STDIN when capturing: my ($out, $err) = do { local *STDIN; capture { ... } }; =head2 Modifying filehandles during a capture Attempting to modify STDIN, STDOUT or STDERR I<during> C<capture> or C<tee> is almost certainly going to cause problems. Don't do that. =head3 Forking inside a capture Forks aren't portable. The behavior of filehandles during a fork is even less so. If Capture::Tiny detects that a fork has occurred within a capture, it will shortcut in the child process and return empty strings for captures. Other problems may occur in the child or parent, as well. Forking in a capture block is not recommended. =head3 Using threads Filehandles are global. Mixing up I/O and captures in different threads without coordination is going to cause problems. Besides, threads are officially discouraged. =head3 Dropping privileges during a capture If you drop privileges during a capture, temporary files created to facilitate the capture may not be cleaned up afterwards. =head2 No support for Perl 5.8.0 It's just too buggy when it comes to layers and UTF-8. Perl 5.8.1 or later is recommended. =head2 Limited support for Perl 5.6 Perl 5.6 predates PerlIO. UTF-8 data may not be captured correctly. =head1 ENVIRONMENT =head2 PERL_CAPTURE_TINY_TIMEOUT Capture::Tiny uses subprocesses internally for C<tee>. By default, Capture::Tiny will timeout with an error if such subprocesses are not ready to receive data within 30 seconds (or whatever is the value of C<$Capture::Tiny::TIMEOUT>). An alternate timeout may be specified by setting the C<PERL_CAPTURE_TINY_TIMEOUT> environment variable. Setting it to zero will disable timeouts. B<NOTE>, this does not timeout the code reference being captured -- this only prevents Capture::Tiny itself from hanging your process waiting for its child processes to be ready to proceed. =head1 SEE ALSO This module was inspired by L<IO::CaptureOutput>, which provides similar functionality without the ability to tee output and with more complicated code and API. L<IO::CaptureOutput> does not handle layers or most of the unusual cases described in the L</Limitations> section and I no longer recommend it. There are many other CPAN modules that provide some sort of output capture, albeit with various limitations that make them appropriate only in particular circumstances. I'm probably missing some.

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. USAGE The following functions are available. None are exported by default. capture ($stdout, $stderr, @result) = capture \&code; $stdout = capture \&code; The "capture" function takes a code reference and returns what is sent to STDOUT and STDERR as well as any return values from the code reference. In scalar context, it returns only STDOUT. If no output was received for a filehandle, it returns an empty string for that filehandle. Regardless of calling context, all output is captured -- nothing is passed to the existing filehandles. It is prototyped to take a subroutine reference as an argument. Thus, it can be called in block form: ($stdout, $stderr) = capture { # your code here ... }; Note that the coderef is evaluated in list context. If you wish to force scalar context on the return value, you must use the "scalar" keyword. ($stdout, $stderr, $count) = capture { my @list = qw/one two three/; return scalar @list; # $count will be 3 }; Also note that within the coderef, the @_ variable will be empty. So don't use arguments from a surrounding subroutine without copying them to an array first: sub wont_work { my ($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 => $err_fh; The filehandles must be read/write and seekable. Modifying the files or filehandles during a capture operation will give unpredictable results. Existing IO layers on them may be changed by the capture. When called in void context, "capture" saves memory and time by not reading back from the capture handles. capture_stdout ($stdout, @result) = capture_stdout \&code; $stdout = capture_stdout \&code; The "capture_stdout" function works just like "capture" except only STDOUT is captured. STDERR is not captured. capture_stderr ($stderr, @result) = capture_stderr \&code; $stderr = capture_stderr \&code; The "capture_stderr" function works just like "capture" except only STDERR is captured. STDOUT is not captured. capture_merged ($merged, @result) = capture_merged \&code; $merged = capture_merged \&code; The "capture_merged" function works just like "capture" except STDOUT and STDERR are merged. (Technically, STDERR is redirected to the same capturing handle as STDOUT before executing the function.) Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. tee ($stdout, $stderr, @result) = tee \&code; $stdout = tee \&code; The "tee" function works just like "capture", except that output is captured as well as passed on to the original STDOUT and STDERR. When called in void context, "tee" saves memory and time by not reading back from the capture handles, except when the original STDOUT OR STDERR were tied or opened to a scalar handle. tee_stdout ($stdout, @result) = tee_stdout \&code; $stdout = tee_stdout \&code; The "tee_stdout" function works just like "tee" except only STDOUT is teed. STDERR is not teed (output goes to STDERR as usual). tee_stderr ($stderr, @result) = tee_stderr \&code; $stderr = tee_stderr \&code; The "tee_stderr" function works just like "tee" except only STDERR is teed. STDOUT is not teed (output goes to STDOUT as usual). tee_merged ($merged, @result) = tee_merged \&code; $merged = tee_merged \&code; The "tee_merged" function works just like "capture_merged" except that output is captured as well as passed on to STDOUT. Caution: STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering. LIMITATIONS Portability Portability is a goal, not a guarantee. "tee" requires fork, except on Windows where "system(1, @cmd)" is used instead. Not tested on any particularly esoteric platforms yet. See the CPAN Testers Matrix <http://matrix.cpantesters.org/?dist=Capture-Tiny> for test result by platform. PerlIO layers Capture::Tiny does its best to preserve PerlIO layers such as ':utf8' or ':crlf' when capturing (only for Perl 5.8.1+) . Layers should be applied to STDOUT or STDERR *before* the call to "capture" or "tee". This may not work for tied filehandles (see below). Modifying filehandles before capturing Generally speaking, you should do little or no manipulation of the standard IO filehandles prior to using Capture::Tiny. In particular, closing, reopening, localizing or tying standard filehandles prior to capture may cause a variety of unexpected, undesirable and/or unreliable behaviors, as described below. Capture::Tiny does its best to compensate for these situations, but the results may not be what you desire. Closed filehandles Capture::Tiny will work even if STDIN, STDOUT or STDERR have been previously closed. However, since they will be reopened to capture or tee output, any code within the captured block that depends on finding them closed will, of course, not find them to be closed. If they started closed, Capture::Tiny will close them again when the capture block finishes. 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.
