For a similar problem, I used Grammar.Entry.find under a Obj.magic.
let type_declaration =
Obj.magic (Grammar.Entry.find str_item "type_declaration")
let type_kind =
Obj.magic (Grammar.Entry.find type_declaration "type_kind")
let type_parameters =
Obj.magic (Grammar.Entry.find type_declaration "type_parameters")
let type_parameter =
Obj.magic (Grammar.Entry.find type_parameters "type_parameter")
As far as I understand, the expression <str_item> is the first entry
where module_binding appears in pa_o.ml which explains the use of:
- type_declaration in my example for type_kind or type_parameters
- type_parameters in my example for type_parameter
So you should try
let module_binding =
Obj.magic (Grammar.Entry.find str_item "module_binding")
