/**
@addtogroup YAPSyntax
describe the syntax for Prolog terms. In a second level we describe
the \a tokens from which Prolog \a terms are
built.
@defgroup Formal_Syntax Syntax of Terms
@ingroup YAPSyntax
@{
Below, we describe the syntax of YAP terms from the different
classes of tokens defined above. The formalism used will be <em>BNF</em>,
extended where necessary with attributes denoting integer precedence or
operator type.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
term
----> subterm(1200) end_of_term_marker
subterm(N) ----> term(M) [M <= N]
term(N) ----> op(N, fx) subterm(N-1)
| op(N, fy) subterm(N)
| subterm(N-1) op(N, xfx) subterm(N-1)
| subterm(N-1) op(N, xfy) subterm(N)
| subterm(N) op(N, yfx) subterm(N-1)
| subterm(N-1) op(N, xf)
| subterm(N) op(N, yf)
term(0) ----> atom '(' arguments ')'
| '(' subterm(1200) ')'
| '{' subterm(1200) '}'
| list
| string
| number
| atom
| variable
arguments ----> subterm(999)
| subterm(999) ',' arguments
list ----> '[]'
| '[' list_expr ']'
list_expr ----> subterm(999)
| subterm(999) list_tail
list_tail ----> ',' list_expr
| ',..' subterm(999)
| '|' subterm(999)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Notes:
+ \a op(N,T) denotes an atom which has been previously declared with type
\a T and base precedence \a N.
+ Since ',' is itself a pre-declared operator with type \a xfy and
precedence 1000, is \a subterm starts with a '(', \a op must be
followed by a space to avoid ambiguity with the case of a functor
followed by arguments, e.g.:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ (a,b) [the same as '+'(','(a,b)) of arity one]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
versus
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+(a,b) [the same as '+'(a,b) of arity two]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
In the first rule for term(0) no blank space should exist between
\a atom and '('.
+
Each term to be read by the YAP parser must end with a single
dot, followed by a blank (in the sense mentioned in the previous
paragraph). When a name consisting of a single dot could be taken for
the end of term marker, the ambiguity should be avoided by surrounding the
dot with single quotes.

/*
* Description:
*
* parser: produces a prolog term from an array of tokens
*
* parser usage: the parser takes its input from an array of token descriptions
* addressed by the global variable 'tokptr' and produces a Term as result. A
* macro 'NextToken' should be defined in 'yap.h' for advancing 'tokptr' from
* one token to the next. In the distributed version this macro also updates
* a variable named 'toktide' for keeping track of how far the parser went
* before failling with a syntax error. The parser should be invoked with
* 'tokptr' pointing to the first token. The last token should have type
* 'eot_tok'. The parser return either a Term. Syntactic errors are signaled
* by a return value 0. The parser builds new terms on the 'global stack' and
* also uses an auxiliary stack pointed to by 'AuxSp'. In the distributed
* version this auxiliary stack is assumed to grow downwards. This
* assumption, however, is only relevant to routine 'ParseArgs', and to the
* variable toktide. conclusion: set tokptr pointing to first token set AuxSp
* Call Parse
*
* VSC: Working whithout known bugs in 87/4/6
*
* LD: -I or +I evaluated by parser 87/4/28
*
* LD: parser extended 87/4/28

@section SICS_attributes SICStus Style attribute declarations.
The YAP library `atts` implements attribute variables in the style of
SICStus Prolog. Attributed variables work as follows:
+ Each attribute must be declared beforehand. Attributes are described
as a functor with name and arity and are local to a module. Each
Prolog module declares its own sets of attributes. Different modules
may have attributes with the same name and arity.
+ The built-in put_atts/2 adds or deletes attributes to a
variable. The variable may be unbound or may be an attributed
variable. In the latter case, YAP discards previous values for the
attributes.
+ The built-in get_atts/2 can be used to check the values of
an attribute associated with a variable.
+ The unification algorithm calls the user-defined predicate
verify_attributes/3 before trying to bind an attributed
variable. Unification will resume after this call.
+ The user-defined predicate
<tt>attribute_goal/2</tt> converts from an attribute to a goal.
+ The user-defined predicate
<tt>project_attributes/2</tt> is used from a set of variables into a set of
constraints or goals. One application of <tt>project_attributes/2</tt> is in
the top-level, where it is used to output the set of
floundered constraints at the end of a query.
Attributes are compound terms associated with a variable. Each attribute
has a <em>name</em> which is <em>private</em> to the module in which the
attribute was defined. Variables may have at most one attribute with a
name. Attribute names are defined through the following declaration:
~~~~~
:- attribute AttributeSpec, ..., AttributeSpec.
~~~~~
where each _AttributeSpec_ has the form ( _Name_/ _Arity_).
One single such declaration is allowed per module _Module_.
Although the YAP module system is predicate based, attributes are local
to modules. This is implemented by rewriting all calls to the
built-ins that manipulate attributes so that attribute names are
preprocessed depending on the module. The `user:goal_expansion/3`
mechanism is used for this purpose.
The attribute manipulation predicates always work as follows:
+ The first argument is the unbound variable associated with
attributes,
+ The second argument is a list of attributes. Each attribute will
be a Prolog term or a constant, prefixed with the <tt>+</tt> and <tt>-</tt> unary
operators. The prefix <tt>+</tt> may be dropped for convenience.
The following three procedures are available to the user. Notice that
these built-ins are rewritten by the system into internal built-ins, and
that the rewriting process <em>depends</em> on the module on which the
built-ins have been invoked.
The user-predicate predicate verify_attributes/3 is called when
attempting to unify an attributed variable which might have attributes
in some _Module_.
Attributes are usually presented as goals. The following routines are
used by built-in predicates such as call_residue/2 and by the
Prolog top-level to display attributes:
Constraint solvers must be able to project a set of constraints to a set
of variables. This is useful when displaying the solution to a goal, but
may also be used to manipulate computations. The user-defined
project_attributes/2 is responsible for implementing this
projection.
The following examples are taken from the SICStus Prolog
manual. The sketches the implementation of a simple finite domain
`solver`. Note that an industrial strength solver would have to
provide a wider range of functionality and that it quite likely would
utilize a more efficient representation for the domains proper. The
module exports a single predicate `domain( _-Var_, _?Domain_)` which
associates _Domain_ (a list of terms) with _Var_. A variable can be
queried for its domain by leaving _Domain_ unbound.
We do not present here a definition for project_attributes/2.
Projecting finite domain constraints happens to be difficult.
~~~~~

( var(Other) -> % must be attributed then
( get_atts(Other, dom(Db)) -> % has a domain?
ord_intersection(Da, Db, Dc),
Dc = [El|Els], % at least one element
( Els = [] -> % exactly one element
Goals = [Other=El] % implied binding
; Goals = [],
put_atts(Other, dom(Dc))% rescue intersection
)
; Goals = [],
put_atts(Other, dom(Da)) % rescue the domain
)
; Goals = [],
ord_intersect([Other], Da) % value in domain?
).
verify_attributes(_, _, []). % unification triggered
% because of attributes
% in other modules
attribute_goal(Var, domain(Var,Dom)) :- % interpretation as goal
get_atts(Var, dom(Dom)).
domain(X, Dom) :-
var(Dom), !,
get_atts(X, dom(Dom)).
domain(X, List) :-
list_to_ord_set(List, Set),
Set = [El|Els], % at least one element
( Els = [] -> % exactly one element
X = El % implied binding
; put_atts(Fresh, dom(Set)),
X = Fresh % may call
% verify_attributes/3
).
~~~~~
Note that the _implied binding_ `Other=El` was deferred until after
the completion of `verify_attribute/3`. Otherwise, there might be a
danger of recursively invoking `verify_attribute/3`, which might bind
`Var`, which is not allowed inside the scope of `verify_attribute/3`.
Deferring unifications into the third argument of `verify_attribute/3`
effectively serializes the calls to `verify_attribute/3`.
Assuming that the code resides in the file domain.yap, we
can use it via:
~~~~~
| ?- use_module(domain).
~~~~~
Let's test it:
~~~~~
| ?- domain(X,[5,6,7,1]), domain(Y,[3,4,5,6]), domain(Z,[1,6,7,8]).
domain(X,[1,5,6,7]),
domain(Y,[3,4,5,6]),
domain(Z,[1,6,7,8]) ?
yes
| ?- domain(X,[5,6,7,1]), domain(Y,[3,4,5,6]), domain(Z,[1,6,7,8]),
X=Y.
Y = X,
domain(X,[5,6]),
domain(Z,[1,6,7,8]) ?
yes
| ?- domain(X,[5,6,7,1]), domain(Y,[3,4,5,6]), domain(Z,[1,6,7,8]),
X=Y, Y=Z.
X = 6,
Y = 6,
Z = 6
~~~~~
To demonstrate the use of the _Goals_ argument of
verify_attributes/3, we give an implementation of
freeze/2. We have to name it `myfreeze/2` in order to
avoid a name clash with the built-in predicate of the same name.
~~~~~
:- module(myfreeze, [myfreeze/2]).
:- use_module(library(atts)).
:- attribute frozen/1.
verify_attributes(Var, Other, Goals) :-
get_atts(Var, frozen(Fa)), !, % are we involved?
( var(Other) -> % must be attributed then
( get_atts(Other, frozen(Fb)) % has a pending goal?
-> put_atts(Other, frozen((Fa,Fb))) % rescue conjunction
; put_atts(Other, frozen(Fa)) % rescue the pending goal
),
Goals = []
; Goals = [Fa]
).
verify_attributes(_, _, []).
attribute_goal(Var, Goal) :- % interpretation as goal
get_atts(Var, frozen(Goal)).
myfreeze(X, Goal) :- put_atts(Fresh, frozen(Goal)), Fresh = X. ~~~~~
Assuming that this code lives in file myfreeze.yap,
we would use it via:
~~~~~
| ?- use_module(myfreeze).
| ?- myfreeze(X,print(bound(x,X))), X=2.
bound(x,2) % side effect
X = 2 % bindings
~~~~~
The two solvers even work together:
~~~~~
| ?- myfreeze(X,print(bound(x,X))), domain(X,[1,2,3]),
domain(Y,[2,10]), X=Y.
bound(x,2) % side effect
X = 2, % bindings
Y = 2
~~~~~
The two example solvers interact via bindings to shared attributed
variables only. More complicated interactions are likely to be found
in more sophisticated solvers. The corresponding
verify_attributes/3 predicates would typically refer to the
attributes from other known solvers/modules via the module prefix in
Module:get_atts/2`.

@defgroup New_Style_Attribute_Declarations hProlog and SWI-Prolog style Attribute Declarations
The following documentation is taken from the SWI-Prolog manual.
Binding an attributed variable schedules a goal to be executed at the
first possible opportunity. In the current implementation the hooks are
executed immediately after a successful unification of the clause-head
or successful completion of a foreign language (built-in) predicate. Each
attribute is associated to a module and the hook attr_unify_hook/2 is
executed in this module. The example below realises a very simple and
incomplete finite domain reasoner.
~~~~~
:- module(domain,
[ domain/2 % Var, ?Domain %
]).
:- use_module(library(ordsets)).
domain(X, Dom) :-
var(Dom), !,
get_attr(X, domain, Dom).
domain(X, List) :-
list_to_ord_set(List, Domain),
v put_attr(Y, domain, Domain),
X = Y.
% An attributed variable with attribute value Domain has been %
% assigned the value Y %
attr_unify_hook(Domain, Y) :-
( get_attr(Y, domain, Dom2)
-> ord_intersection(Domain, Dom2, NewDomain),
( NewDomain == []
-> fail
; NewDomain = [Value]
-> Y = Value
; put_attr(Y, domain, NewDomain)
)
; var(Y)
-> put_attr( Y, domain, Domain )
; ord_memberchk(Y, Domain)
).
% Translate attributes from this module to residual goals %
attribute_goals(X) -->
{ get_attr(X, domain, List) },
[domain(X, List)].
~~~~~
Before explaining the code we give some example queries:
The predicate `domain/2` fetches (first clause) or assigns
(second clause) the variable a <em>domain</em>, a set of values it can
be unified with. In the second clause first associates the domain
with a fresh variable and then unifies X to this variable to deal
with the possibility that X already has a domain. The
predicate attr_unify_hook/2 is a hook called after a variable with
a domain is assigned a value. In the simple case where the variable
is bound to a concrete value we simply check whether this value is in
the domain. Otherwise we take the intersection of the domains and either
fail if the intersection is empty (first example), simply assign the
value if there is only one value in the intersection (second example) or
assign the intersection as the new domain of the variable (third
example). The nonterminal `attribute_goals/3` is used to translate
remaining attributes to user-readable goals that, when executed, reinstate
these attributes.
@}
@{
@defgroup CohYroutining Co-routining
Prolog uses a simple left-to-right flow of control. It is sometimes
convenient to change this control so that goals will only execute when
sufficiently instantiated. This may result in a more "data-driven"
execution, or may be necessary to correctly implement extensions such
as negation by failure.
Initially, YAP used a separate mechanism for co-routining. Nowadays, YAP uses
attributed variables to implement co-routining.
Two declarations are supported:
+ block/1
The argument to `block/1` is a condition on a goal or a conjunction
of conditions, with each element separated by commas. Each condition is
of the form `predname( _C1_,..., _CN_)`, where _N_ is the
arity of the goal, and each _CI_ is of the form `-`, if the
argument must suspend until the first such variable is bound, or
`?`, otherwise.
+ wait/1
The argument to `wait/1` is a predicate descriptor or a conjunction
of these predicates. These predicates will suspend until their first
argument is bound.
The following primitives can be used:
- freeze/2
- dif/2
- when/2
- frozen/2
