:- use_module(library(help)).(can be autoloaded)
topics(s)to give help for. Notations for What are:
- This ambiguous form is most commonly used and shows all matching
documents. For example:
- Give help on predicates with matching Name/Arity. Arity may be unbound.
- Give help on the matching DCG rule (non-terminal)
- Give help on the matching Prolog arithmetic functions.
- Give help on the matching C interface function
- Show the section from the manual with matching Label.
If an exact match fails this predicates attempts fuzzy matching and, when successful, display the results headed by a warning that the matches are based on fuzzy matching.
If possible, the results are sent through a pager such as the
less program. This behaviour is controlled by the Prolog
help_pager. See section level documentation.
