package Spreadsheet::Template::Generator;

# ABSTRACT: create new templates from existing spreadsheets
use Class::Load 'load_class';
use JSON;
=head1 SYNOPSIS
use Spreadsheet::Template::Generator;
my $generator = Spreadsheet::Template::Generator->new;
open my $fh, '>:encoding(utf8)', 'out.json';
$fh->print($generator->generate($filename));
=head1 DESCRIPTION
This module is used to create new templates from existing spreadsheets. You can
then modify this output to be suitable to use as input for
L<Spreadsheet::Template> by, for instance, adding in L<Text::Xslate> directives
to use your actual data, rather than the hardcoded data in the original
spreadsheet.
=cut
=attr parser_class
The class to use for parsing the spreadsheet. Defaults to
L<Spreadsheet::Template::Generator::Parser::XLSX>.
=cut
has parser_class => (
is => 'ro',
isa => 'Str',
default => 'Spreadsheet::Template::Generator::Parser::XLSX',
);
=attr parser_options
Options to pass to the parser constructor. Defaults to an empty hashref.
=cut
has parser_options => (
is => 'ro',
isa => 'HashRef',
default => sub { {} },
);
has parser => (
is => 'ro',
does => 'Spreadsheet::Template::Generator::Parser',
lazy => 1,
default => sub {
my $self = shift;
my $class = $self->parser_class;
load_class($class);
return $class->new(
%{ $self->parser_options }
);
},
);
=method generate($filename)
Returns a string containing the JSON representation of the data contained in
the spreadsheet file C<$filename>. This representation is documented in
L<Spreadsheet::Template>.
=cut
sub generate {
my $self = shift;
my ($filename) = @_;
my $data = $self->parser->parse($filename);
return JSON->new->pretty->canonical->encode($data);
