Module::Bundled::Files(3) Access files bundled with Module

VERSION

Version 0.03

SYNOPSIS

Access files installed with your module without needing to specify an install location on the target filesystem.

Setup

In Build.PL: 

  my $build = new Module::Build(...);
  map{$build->add_build_element($_);}
    qw{txt html tmpl};
  # installs all .txt, .html and .tmpl files found in the lib/ tree

Create files: 

  Build.PL
  lib/
    My/
      Module.pm
      Module/
        index.html
        data.txt
        form.tmpl

Object-Oriented Interface

  use base qw{Module::Bundled::Files};
  
  if($self->mbf_exists('data.txt')){...}
  
  my $filename = $self->mbf_path('data.txt');
  # $filename = '/usr/local/share/perl/5.8.7/My/Module/data.txt';
  open my $fh, '<', $filename or die $@;
  
  my $fh = $self->mbf_open('data.txt');
  while(<$fh>)
  {
    ...
  }
  
  my $data = $self->mbf_read('data.txt');

Non-Object-Oriented Interface

  use Module::Bundled::Files qw{:all};
  my $object = new Other::Object;
  if(mf_exists($other,'otherfile.txt')){...}
  my $filename = mbf_path($object,'otherfile.txt');
  open my $fh, '<', $filename or die $@;
  
  my $fh = mbf_open($object,'otherfile.txt');
  while(<$fh>)
  {
    ...
  }
  
  my $data = mbf_read($object,'otherfile.txt');

DESCRIPTION

This module provides an simple method of accessing files that need to be bundled with a module.

For example, a module My::Module, which needs to access a separate file data.txt.

In your development directory you would place your data.txt in your lib/My/Module/ directory. 

  lib/
    My/
      Module.pm
      Module/
        data.txt

Using add_build_element(...) in your Build.PL file allows the data.txt file to be installed in the same relative location.

The file(s) can then be accessed using the mbf_* functions provided by this module.

EXPORT

The following functions can be exported if you will not be using the Object-Oriented Interface. 

  :all
    mbf_validate
    mbf_dir
    mbf_exists
    mbf_path
    mbf_open
    mbf_read

FUNCTIONS

mbf_validate(FILENAME)

Returns true if the filename does not contain illegal sequences (i.e. '..')

Dies if filename is invalid.

mbf_dir([MODULE])

Returns the path of the directory where all files would be installed.

The non-OO interface requires an object reference or module name as the only parameter.

mbf_exists([MODULE,] FILENAME)

Returns true of the named file has been bundled with the module.

The non-OO interface requires an object reference or module name as the first parameter.

mbf_path([MODULE,] FILENAME)

Returns the full path to the named file. Dies if the file does not exist.

Will look for file in inherited classes (by reading @ISA) if the file is not found for the derived class. @ISA navigation is the same as per Perl searching for methods. See Class::ISA for more details.

The non-OO interface requires an object reference or module name as the first parameter.

mbf_open([MODULE,] FILENAME)

Returns an open file handle for the named file. Dies if the file does not exist.

The non-OO interface requires an object reference or module name as the first parameter.

mbf_read([MODULE,] FILENAME)

Returns the content of the named file. Dies if the file does not exist.

The non-OO interface requires an object reference or module name as the first parameter.
