Write __DATA__ section files for Data::Section, Data::Section::Simple or Mojo::Loader::data_section
This code:
use strict;
use warnings;
use Data::Section::Writer;
use Path::Tiny qw( path );
Data::Section::Writer
->new( perl_filename => "foo.pl" )
->add_file( "hello.txt", "hello world" )
->add_file( "a.out", path("a.out")->slurp_raw, 'base64' )
->update_file;Will add this to the bottom of foo.pl
__DATA__
@@ a.out (base64)

This class is an interface for updating the __DATA__ section of your Perl module or script programmatically
for it to work with one of the many modules that allows for multiple files in a __DATA__ section, such as
Data::Section, Data::Section::Simple, Data::Section::Pluggable or Mojo::Loader.
Data::Section uses a different header format by default, but you can still use this module with it
if you set header_re to qr/^@@ (.*)$/.
The name of the Perl source file. If not provided then the source for the caller will be used.
$writer->add_file($text_filename, $content);
$writer->add_file($binary_filename, $content, 'base64');
Add a file. Binary files can be encoded using base64. Such binaries files are
only supported by Mojo::Loader at the moment.
my $perl = $writer->render_section;Returns the __DATA__ section.
$writer->update_file;
Update the existing Perl source file, OR create a new Perl source file with just the __DATA__ section.
[version 0.02]
Starting with version 0.02, this method will not write to the file if the content won't change.
[version 0.02]
my $bool = $self->unchanged;Returns:
-
`undef`
If </update_file> hasn't been called yet.
-
`0`
If the last call to </update_file> modified the file.
-
`1`
If the last call to </update_file> did not modify the file.
Added text files will get an added trailing new line if they do not already have them. This is a requirement of the format used by the data section modules.
For binary files (base64 encoded) the content returned by Mojo::Loader should be identical.
Not tested, and probably not working for Windows formatted text files, though patches for this are welcome.
