Subject: Helper methods I'm using
Download (untitled) / with headers
text/plain 1.1k
As requested, here are the helper methods I'm currently using in PPI::Analyze (coming to a CPAN mirror near you! ... when I get the time). Some of them could be rewritten to use $doc->find() instead of xpmatch() and they're not terribly robust (see. no error handling), but here you go: sub PPI::Element::xpmatch { my($doc, $path) = @_; return PPI::XPath->new($doc)->match($path); } sub PPI::Element::is_var { return $_[0]->class eq 'Token::Symbol'; } sub PPI::Element::is_sub { my $n = shift; return 1 if $n->class eq 'Statement::Sub'; return 1 if $n->is_anon_sub; } ## it'd be nice if anon subs were Statement::Sub instead of Structure::Block ... sub PPI::Element::is_anon_sub { return $_[0]->class eq 'Structure::Block' and $_[0]->sprevious_sibling->content eq 'sub'; } sub PPI::Element::is_in_sub { my $n = shift; $n->is_sub and return 1 while $n = $n->parent; return; } sub PPI::Document::subs { return $_[0]->xpmatch('//Statement::Sub'), grep $_->is_anon_sub, $_[0]->xpmatch('//Structure::Block'); } sub PPI::Document::vars { return uniq $_[0]->xpmatch('//Token::Symbol'); }
