NAME
File::Maker - mimics a make by loading a database and calling targets methods
SYNOPSIS
#####
# Subroutine interface
#
use File::Maker qw(load_db);
\%data = load_db($pm);
######
# Object interface
#
require File::Maker;
$maker = $maker->load_db($pm);
$maker->make_targets(\%targets, @targets, \%options );
$maker->make_targets(\%targets, \%options );
$maker = new File::Maker(@options);
Generally, if a subroutine will process a list of options, "@options", that subroutine will also process an array reference, "\@options", "[@options]", or hash reference, "\%options", "{@options}". If a subroutine will process an array reference, "\@options", "[@options]", that subroutine will also process a hash reference, "\%options", "{@options}". See the description for a subroutine for details and exceptions.
DESCRIPTION
When porting low level C code from one architecture to another, makefiles do provide some level of automation and save some time. However, once Perl or another high-level language is up and running, the high-level language usually allows much more efficient use of programmers time; otherwise, whats point of the high-level language. Thus, makes great economically sense to switch from makefiles to high-level language.
The "File::Maker" program module provides a "make" style interface as shown in the herein above. The "@targets" contains a list of targets that mimics the targets of a "makefile". The targets are subroutines written in Perl in a separate program module from the "File::Maker". The separate target program module inherits the methods in the "File::Maker" program module as follows:
use File::Maker;
use vars qw( @ISA );
@ISA = qw(File::Maker);
The "File::Maker" methods will then find the target subroutines in the separate target program module.
The "File::Maker" provides for the loading of a hash from a program module to provide for the capabilities of "defines" in a "makefile". The option "pm =" $file> tells "File::Maker" to load a database from the __DATA__ section of a program module that is in the Tie::Form format. The "Tie::Form" format is a very flexible lenient format that is about as close to a natural language form and still have the precision of being machine readable. This provides a more flexible alternative to the defines in a "makefile". The define hash is in a separate, very flexible form program module. This arrangement allows one target program module that inherits the "File::Maker" program module to produce as many different outputs as there are Tie::Form program modules.
METHODS
load_db
\%data = load_db($pm);
$maker = $maker->load_db($pm);
The "load_db" subroutine loads the "__DATA__" of "$pm" using "Tie::Form" progrma module. The results are return as a hash. If called as a object, the objec "$maker" have hash data. The return keys are as follows:
FormDB_File the absoute file of $pm
FormDB_PM $pm
FormDB_Record __DATA__ section of $pm
FormDB ordered name,value pairs of __DATA__ section
make_targets
$maker->make_targets(\%targets, @targets);
$maker->make_targets(\%targets, @targets, \%options);
$maker->make_targets(\%targets);
$maker->make_targets(\%targets, \%options);
The "make_targets" subroutine executes the "@targets" in order after substituing an expanded list "$target[$targets[$i]}" list if it exists, as follows:
$result = $self->$target[$i]( @args )
The "@args" do not exists unless the "$taget[$i]" is itself an array reference in which case the "make_targets" subroutine assumes the array referenced is
[$target, @args]
The return "$result" may be a reference to an object, usually the same class as the original $result, or a "$success" flag of 1 or undef. If "$result" is a reference, the "make_targets" subroutine will set <$self> to the new object "$result". Thus, by returning an reference, a target may pass data to the next targe or even change the class of "$self".
new
$maker = new File::Maker(@options);
$maker = new File::Maker(\@options);
$maker = new File::Maker(\%options);
The "new" subroutine returns an object whose object data is a hash reference of "@options".
REQUIREMENTS

QUALITY ASSURANCE
Running the test script "Maker.t" verifies the requirements for this module. The "tmake.pl" cover script for Test::STDmaker automatically generated the "Maker.t" test script, "Maker.d" demo script, and "t::File::Maker" STD program module POD, from the "t::File::Maker" program module contents. The "tmake.pl" cover script automatically ran the "Maker.d" demo script and inserted the results into the 'DEMONSTRATION' section above. The "t::File::Maker" program module is in the distribution file File-Maker-$VERSION.tar.gz.

The \%targets contains a list of targets that are supplied by the using program module. The option "-pm = file" tells "File::Maker" to load a database from the __DATA__ section of a program module that is in the Tie::Form format. This provides a more flexible alternative to the defines and macros in a "makefile".

CORRECTIVE:
Probably differences in New Line for Unix versus Microsoft. Thus,
run the "__DATA__" through the smartNL routine to see if File-Maker
has a better reception in the UNIX world.
File-Maker-0.04
Had "DataPort::Maker" for POD NAME. Changed POD NAME to
"File::Maker"
\item File-Maker-0.05
Changed synopsis for a target so that it now nay return a "$self"
object reference as well as "$success". This allows targets to pass
data between each other via the "$self" underlying data or even
create a different class object for $self.
3.4 Adaptation data.
This installation requires that the installation site has the Perl programming language installed. There are no other additional requirements or tailoring needed of configurations files, adaptation data or other software needed for this installation particular to any installation site.
