Usage: tokeniser(VRML, Tokens)
- Description: This predicate will perform the parsing of the VRML code. The result will be tokens that will be the source for producing the Prolog terms of the VRML code. This is done in the parser module. From these terms analysis, changing, and any thing that you want to do with VRML code from Prolog programming language. We perform the predicate with a catch call to be able to output error messages if encountered.
- Call and exit should be compatible with:
VRML is a list of atms.
(basic_props:list/2)
Tokens is a list of terms.
(basic_props:list/2)
- The following properties should hold at call time:
VRML is currently a term which is not a free variable.
(term_typing:nonvar/1)
Tokens is a free variable.
(term_typing:var/1)
- PREDICATE: token_read/3:
-
