NAME

Data::Section::Simple - Read data from __DATA__

SYNOPSIS

  use Data::Section::Simple qw(get_data_section);
  # Functional interface -- reads from caller package __DATA__
  my $all = get_data_section; # All data in hash reference
  my $foo = get_data_section('foo.html');
  # OO - allows reading from other packages
  my $reader = Data::Section::Simple->new($package);
  my $all = $reader->get_data_section;
  __DATA__
  @@ foo.html
  <html>
   <body>Hello</body>
  </html>
  @@ bar.tt
  [% IF true %]
    Foo
  [% END %]

DESCRIPTION

Data::Section::Simple is a simple module to extract data from "__DATA__" section of the file.

LIMITATIONS

As the name suggests, this module is a simpler version of the excellent Data::Section. If you want more functionalities such as merging data sections or changing header patterns, use Data::Section instead.

This module does not implement caching (yet) which means in every "get_data_section" or "get_data_section($name)" this module seeks and re-reads the data section. If you want to avoid doing so for the better performance, you should implement caching in your own caller code.

BUGS

__DATA__ appearing elsewhere

If you data section has literal "__DATA__" in the data section, this module might be tricked by that. Although since its pattern match is greedy, "__DATA__" appearing before the actual data section (i.e. in the code) might be okay.

This is by design -- in theory you can "tell" the DATA handle before reading it, but then reloading the data section of the file (handy for developing inline templates with PSGI web applications) would fail because the pos would be changed.

If you don't like this design, again, use the superior Data::Section.

utf8 pragma

If you enable utf8 pragma in the caller's package (or the package you're inspecting with the OO interface), the data retrieved via "get_data_section" is decoded, but otherwise undecoded. There's no reliable way for this module to programmatically know whether utf8 pragma is enabled or not: it's your responsibility to handle them correctly.
