package HTML::Tidy5::Message;
use 5.010001;
use warnings;

=head1 NAME
HTML::Tidy5::Message - Message object for the Tidy functionality
=head1 EXPORTS
None. It's all object-based.
=head1 METHODS
Almost everything is an accessor.
=head2 new( $file, $line, $column, $text )
Create an object. It's not very exciting.
C<$file> can be C<undef> or an empty string, in which case it will not appear in messages.
=cut
sub new {
my $class = shift;
my $file = shift;
my $type = shift;
my $line = shift || 0;
my $column = shift || 0;
my $text = shift;
# Add an element that says what tag caused the error (B, TR, etc)
# so that we can match 'em up down the road.
my $self = {
_file => $file,
_type => $type,
_line => $line,
_column => $column,
_text => $text,
};
bless $self, $class;
return $self;
}
=head2 as_string()
Returns a nicely-formatted string for printing out to stdout or some similar user thing.
=cut
sub as_string {
my $self = shift;
my %strings = (
1 => 'Info',
2 => 'Warning',
3 => 'Error',
);
my $msg = $strings{$self->type} . ': ' . $self->text;
if ( $self->line && $self->column ) {
$msg = sprintf( '(%d:%d) %s', $self->line, $self->column, $msg );
}
my $file = $self->file // '';
if ( $file ne '' ) {
$msg = "$file $msg";
}
return $msg;
}
=head2 file()
Returns the filename of the error, as set by the caller.
=head2 type()
Returns the type of the error. This will either be C<TIDY_ERROR>,
or C<TIDY_WARNING>.
=head2 line()
Returns the line number of the error, or 0 if there isn't an applicable
line number.
=head2 column()
Returns the column number, or 0 if there isn't an applicable column
number.
=head2 text()
Returns the text of the message. This does not include a type string,
like "Info: ".
=cut
sub file { my $self = shift; return $self->{_file} }
sub type { my $self = shift; return $self->{_type} }
sub line { my $self = shift; return $self->{_line} }
sub column { my $self = shift; return $self->{_column} }
sub text { my $self = shift; return $self->{_text} }
