Devel::hdb::App::PackageInfo - Get information about packages and subroutines
Returns a JSON-encoded hash with two keys: "packages" containing a list of namespaces within the requested package, and "subs" containing a list of debuggable subroutine names in the requested package. Subroutines are considered debuggable is there is an entry in %DB::sub for them.
Given a fully-qualified subroutine name, including package, in the format Package::SubPackage::subroutine, returns a JSON-encoded hash with these keys: file => Filename this subroutine was defined start => Line number in the file the subroutine starts end => Line in the file the subroutine ends source => Original source file of the subroutine text source_line => Line in the original source file
source and source_line can differ from file and start in the case of subroutines defined inside of a string eval. In this case, "file" will be a string like (eval 23)[/some/file/path/module.pm:123] representing the text that was eval-ed, and "start" will be the line within that text where the subroutine was defined. "source" would be /some/file/path/module.pm showing where in the original source code the text came from, and "source_line" would be 123, the line in the original source file.
