annotate libinterp/parse-tree/oct-parse.in.yy @ 18262:69990d5edcc2

Allow to parse external methods declaration in classdef files. * libinterp/parse-tree/parser.h (octave_base_parser::start_classdef_external_method, octave_base_parser::finish_classdef_external_method): New methods. * libinterp/parse-tree/oct-parse.in.yy (octave_base_parser::start_classdef_external_method, octave_base_parser::finish_classdef_external_method): Likewise. (%destructor): Add missing directives for classdef-related types. (method, method_decl, method_decl1): New nonterminal rules. (methods_list): Use "method" on terminal. * libinterp/octave-value/ov-classdef.cc (cdef_package::cdef_package_rep::meta_subsref): When searching for package methods, only issue an error when error_state is not set.
