NAME

IO::MultiPipe - Allows for error checking on a command involving multiple pipes.

CONTENTS

VERSION

Version 0.0.0

SYNOPSIS

Normally if a part of a pipe fails, depending on the location, it won’t be detected. This breaks down a command involving pipes and runs each command seperately.

It uses open3 to run each chunk of the pipe.



    use IO::MultiPipe;

    my $pipes = IO::MultiPipe->new();
   
    #This sets the pipe that will be run.
    $pipes->set(sed s/-// | sed s/123/abc/ | sed s/ABC/abc/);
    if ($pipes->{error}){
        print "Error!\n";
    }
   
    #123-ABCxyz through the command set above.
    my $returned=$pipes->run(123-ABCxyz);



FUNCTIONS

    new

Initializes the object.

    run

This runs the data through the pipe.

    set

Sets the command that will be used.



    $pipes->set(sed s/-// | sed s/123/abc/ | sed s/ABC/abc/);
    if ($pipes->{error}){
        print "Error!\n";
    }



    errorBlank

This blanks the error storage and is only meant for internal usage.

It does the following.



    $self->{error}=undef;
    $self->{errorString}="";



ERROR CODES

This is contained in ’$pipe->{error}’. Any time this is true, there is an error.

    1

No command passed to the set function.

    2

Command contains null section.

    3

No command has been set yet. The ’set’ needs called first before calling ’run’.

    4

Opening the command failed.

    5

The command errored.
