- my $lexer = Compiler::Lexer->new($options);
- create new instance. You can create object from
$options in hash reference.
options list
- filename
- verbose : includes token of Pod, Comment and WhiteSpace
- $lexer->tokenize($script);
- get token objects includes parameter of 'name' or 'type' or 'line' and so
on. This method requires perl source code in string.
- $lexer->set_library_path(['path1', 'path2' ...])
- set libraries path for reading recursively. Default paths are
@INC.
- $lexer->recursive_tokenize($script)
- get hash reference like { 'module_nameA' => [], 'module_nameB' => []
... }. This method requires per source code in string.
- $lexer->get_used_modules($script);
- get names of used module. This method requires perl source code in
string.
