@node Evaluator Behaviour
@subsection Evaluator Behaviour
@c FIXME::martin: Maybe this node name is bad, but the old name clashed with
@c `Evaluator options' under `Options and Config'.
The behaviour of Guile's evaluator can be modified by manipulating the
evaluator options. For more information about options, @xref{User level
options interfaces}.
@c FIXME::martin: Why aren't these procedure named like the other options
@c procedures?
@deffn {Scheme Procedure} traps [setting]
Display the current settings of the evaluator traps options. If
@var{setting} is omitted, only a short form of the current evaluator
traps options is printed. Otherwise, @var{setting} should be one of the
following symbols:
@table @code
@item help
Display the complete option settings.
@item full
Like @code{help}, but also print programmer options.
@end table
@end deffn
@deffn {Scheme Procedure} trap-enable option-name
@deffnx {Scheme Procedure} trap-disable option-name
@deffnx {Scheme Procedure} trap-set! option-name value
Modify the evaluator options. @code{trap-enable} should be used with boolean
options and switches them on, @code{trap-disable} switches them off.
@code{trap-set!} can be used to set an option to a specific value.
See @ref{Evaluator trap options} for more information on the available
trap handlers.
