8 Test::Valgrind::Parser::Suppressions::Text - Parse valgrind suppressions output as text blocks.
16 our $VERSION = '1.02';
20 This is a L<Test::Valgrind::Parser> object that can extract suppressions from C<valgrind>'s text output.

30 Generated reports are C<Test::Valgrind::Report::Suppressions> objects.
31 Their C<data> member contains the raw text of the suppression.

37 =head2 C<parse $session, $fh>
39 Parses the filehandle C<$fh> fed with the output of F<valgrind --gen-suppressions=all> and sends a report to the session C<$session> for each suppression.
