Hi all,
I would like to use modules from the compiler to outsource parsing a
definition module. I wrote the code beneath based on what I saw in the
compiler code and some hacking. It works, but I'm not sure if this is
the preferred way to use cocl's parser (if there *is* a preferred way).
In particular, I wasn't sure how I was supposed to create a new heap /
hashtable / pointer. Is it correct to use init_identifiers, nilPtr, and
IC_Module NoQualifiedIdents?
init_identifiers and IC_Module NoQualifiedIdents are correct. nilPtr
can be removed.
Any help is much appreciated. Thanks in advance.
You can pass mod_id.boxed_ident from putIdentInHashTable to
wantModule instead of id and remove the definitions of ptr and id.
Kind regards,
