NAME

       App::Yath::Util - General utilities for yath that do not fit anywhere else.

DESCRIPTION

       This package exports several tools used throughout yath that did not fit into any other
       package.

SYNOPSIS

           use App::Yath::Util qw{
               find_pfile
               find_in_updir
               is_generated_test_pl
               fit_to_width
               isolate_stdout
               find_yath
           };

EXPORTS

       Note that nothing is exported by default, you must request each function to import.

       $path_to_pfile = find_pfile($settings, %params)
           The first argument must be an instance of Test2::Harness::Settings.

           Currently the only supported param is "vivify", when set to true the pfile will be
           created if one does not already exist.

           The pfile is a file that tells yath that a persistent runner is active, and how to
           communicate with it.

       $path_to_file = find_in_updir($file_name)
           Look for $file_name in the current directory or any parent directory.

       $bool = is_generated_test_pl($path_to_test_file)
           Check if the specified test file was generated by the "yath init" command.

       fit_to_width($width, $join, $text)
           This will split the $text on space, and then recombine it using $join inserting
           newlines as necessary in an attempt to fit the text into $width horizontal characters.
           If any words are larger than $width they will not be split and text-wrapping may occur
           if used for terminal display.

       $stdout = isolate_stdout()
           This will close STDOUT and reopen it to point at STDERR. The result of this is that
           any print statement that does not specify a fielhandle will print to STDERR instead of
           STDOUT, in addition any print directly to STDOUT will instead go to STDERR. A
           filehandle to the real STDOUT is returned for you to use when you actually want to
           write to STDOUT.

           This is used by some yath processes that need to print structured data to STDOUT
           without letting any third part modules they may load write to the real STDOUT.

       $path_to_script = find_yath()
           This will attempt to find the "yath" command line script. When possible this will
           return the path that was used to launch yath. If yath was not run to start the process
           it will search the paths specified in the Config module. This will throw an exception
           if the script cannot be found.

           Note: The result is cached so that subsequent calls will return the same path even if
           something installs a new yath script in another location that would otherwise be found
           first. This guarentees that a single process will not switch scripts.
