NAME IPC::Run3::Simple - Simple utility module to make the easy to use IPC::Run3 even more easy to use. VERSION This document describes v0.004 of IPC::Run3::Simple - released February 15, 2012 as part of IPC-Run3-Simple. SYNOPSIS use IPC::Run3::Simple; # Dead simple, ignoring system error and getting rid of the final newline in # the output. IPC::Run3::Simple::chomp_out( 1 ); my ( $out, $err ) = run3( [qw( ls -AGlh )] ); die $err if $err; # Manipulate $out however you want. # Dump file listing into array, then chomp the array, ignoring any errors. IPC::Run3::Simple::chomp_out( 1 ); my $args = { 'cmd' => [qw( ls -AGlh )], 'stdout' => \my @files, }; for my $file ( @files ) { print "filename: $file\n" } METHODS chomp_err If a false value is passed, run3 will not chomp any error if it's stored in a scalar or array ref. Default is to chomp any error. chomp_out If a false value is passed, run3 will not chomp the result if it's stored in a scalar or array ref. Default is to chomp any result. croak_on_err If a false value is passed, run3 will return instead of croaking on error. Default is to croak on error. default_stdin Set the default stdin to be used. default_stdout Set the default stdout be used. default_stderr Set the default stderr to be used. run3 This method is exported into the calling namespace. Expects either a reference to an array or a reference to a hash. If a reference to an array is passed in then it is assumed to be a list of the command and option(s) to be run. A list containing the results, errors and exit code (in that order) will be returned. See SYNOPSIS for an example. If a reference to a hash is passed in, the following information is expected: See IPC::Run3 documentation for possible values for each of these keys. 'cmd' Required 'stdin' Optional 'stdout' Optional 'stderr' Optional 'options' Optional Note: If any of stdin, stdout or stderr are not passed in the hash 'undef' will be used in their place. In addition, the following variables can be set, either in the hash passed in or globally via $IPC::Run3::Simple::VARIABLE. CROAK_ON_ERR If true, run3 will 'croak $stderr' instead of returning if $stderr contains anything. Default is to return instead of croaking. CHOMP_OUT If true, run3 will 'chomp $$stdout' if stdout is a scalar reference or 'chomp @$stdout' if stdout is an array reference. Otherwise, it has no effect. If false, nothing will be done to the output of the call. Default is true. CHOMP_ERR If true, run3 will 'chomp $$stderr' if stderr is a scalar reference or 'chomp @$stderr' if stderr is an array reference. Otherwise, it has no effect. If false, nothing will be done to the error output of the call. Default is true. INSTALLATION See perlmodinstall for information and options on installing Perl modules.
