Games::Nonogram::Loader::File

SYNOPSIS

use Games::Nonogram::Loader::File;
my ($h, $w, @lines) = Games::Nonogram::Loader::File->load( $file );

DESCRIPTION

This is used internally to load puzzle data from a file.

loader ignores lines which start with #

loader reads row clues first: a set of row clues per a line, and the row clues should be comma-separated.

loader regards the first blank line as the end of the row clues.

loader reads column clues, then, in the same manner.

loader regards end-of-file or the second blank line as the end of the column clues.

In short, a file like below

# row clues
1
3
1,1,1
3
1

# column clues
1
1,1
5
1,1
1

would produce a puzzle like below.

__X__
_XXX_
X_X_X
_XXX_
__X__

METHOD

load

takes a filename as an argument and reads its data.
