Usage: (appendo x y z)

A relation where x, y, and z are proper collections, such that z is x appended to ySource

Usage: (conda & clauses)

Soft cut. Once the head of a clause has succeeded all other clauses will be ignored. Non-relational.Source

Usage: (conde & clauses)

Logical disjunction of the clauses. The first goal in a clause is considered the head of that clause. Interleaves the execution of the clauses.Source

Usage: (condu & clauses)

Committed choice. Once the head (first goal) of a clause has succeeded, remaining goals of the clause will only be run once. Non-relational.Source

Usage: (conso a d l)

A relation where l is a collection, such that a is the first of l and d is the rest of l. If ground d must be bound to a proper tail.Source

Usage: (defne & rest)

Define a goal fn. Supports pattern matching. All patterns will be tried. See conde.Source

Usage: (distincto l)

A relation which guarantees no element of l will unify with another element of l.Source

Usage: (everyg g coll)

A pseudo-relation that takes a coll and ensures that the goal g succeeds on every element of the collection.Source

Usage: (featurec x fs)

Ensure that a map contains at least the key-value pairs in the map fs. fs must be partially instantiated - that is, it may contain values which are logic variables to support feature extraction.Source

Usage: (firsto l a)

A relation where l is a collection, such that a is the first of lSource

Usage: (fix-constraints a)

A goal to run the constraints in cq until it is empty. Of course running a constraint may grow cq so this function finds the fixpoint.Source

Usage: (fnc args & body)

Define an anonymous constraint that can be used with the unifier: (let [oddc (fnc [x] (odd? x))] (unifier {:a '?a} {:a 1} :when {'?a oddc}) ;;=> {:a 1} (unifier {:a '?a} {:a 2} :when {'?a oddc}) ;;=> nil ) Note, the constraint will not run until all arguments are fully ground. Use defnc to define a constraint and assign a toplevel var.Source

Usage: (fne & rest)

Define an anonymous goal fn. Supports pattern matching. All patterns will be tried. See conde.Source

Usage: (fresh [& lvars] & goals)

Creates fresh variables. Goals occuring within form a logical conjunction.Source

Usage: (is u v op)

Set the value of a var to value of another var with the operation applied. Non-relational.Source

Usage: (lcons a d)

Constructs a sequence a with an improper tail d if d is a logic variable.Source

Usage: (llist f s) (llist f s & rest)

Constructs a sequence from 2 or more arguments, with the last argument as the tail. The tail is improper if the last argument is a logic variable.Source

Usage: (lvaro v)

A goal that succeeds if the argument is fresh. v must be a logic variable. Non-relational.Source

Usage: (map->PMap m#)

Factory function for class clojure.core.logic.PMap, taking a map of keywords to field values.Source

Usage: (map->SubstValue m#)

Factory function for class clojure.core.logic.SubstValue, taking a map of keywords to field values.Source

Usage: (map->SuspendedStream m#)

Factory function for class clojure.core.logic.SuspendedStream, taking a map of keywords to field values.Source

Usage: (master argv cache)

Take the argument to the goal and check that we don't have an alpha equivalent cached answer term in the cache. If it doesn't already exist in the cache add the new answer term.Source

Usage: (matche xs & cs)

Pattern matching macro. All patterns will be tried. See conde.Source

Usage: (member1o x l)

Like membero but uses to disequality further constraining the results. For example, if x and l are ground and x occurs multiple times in l, member1o will succeed only once.Source

Usage: (membero x l)

A relation where l is a collection, such that l contains x.Source

Usage: (nafc c & args)

EXPERIMENTAL: negation as failure constraint. All arguments to the goal c must be ground. If some argument is not ground the execution of this constraint will be delayed.Source

Usage: (nonlvaro v)

A goal that succeeds if the argument is not fresh. v must be a logic variable. Non-relational.Source

Usage: (or* goals)

A function version of conde, which takes a list of goals and tries them as if via conde. Note that or* only does disjunction, ie (or* [a b c]) is the same as (conde [a] [b] [c]). If you need something like (conde [a b] [c]), you can use and*, or all: (or* [(and* a b) c]).Source

Usage: (partial-map m)

Given map m, returns partial map that unifies with maps even if it doesn't share all of the keys of that map.Source

Usage: (permuteo xl yl)

A relation that will permute xl into the yl. May not terminate if xl is not ground.Source

Usage: (project [& vars] & goals)

Extract the values bound to the specified logic vars. Non-relational.Source

Usage: (run-nc* & goals)

Executes goals until results are exhausted. Does not occurs-check.Source

Usage: (tabled args & grest)

Macro for defining a tabled goal. Prefer ^:tabled with the defne/a/u forms over using this directly.Source

Usage: (trace-lvars title & lvars)

Goal for tracing the values of logic variables.Source

Usage: (waiting-stream-check w success-cont failure-cont)

Take a waiting stream, a success continuation, and a failure continuation. If we don't find any ready suspended streams, invoke the failure continuation. If we find a ready suspended stream calculate the remainder of the waiting stream. If we've reached the fixpoint just call the thunk of the suspended stream, otherwise call mplus on the result of the thunk and the remainder of the waiting stream. Pass this result to the success contination.Source

Usage: (<= x y)

Goal for testing whether x is less than or equal to y. Non-relational.Source

Usage: (>= x y)

Goal for testing whether x is greater than or equal to y. Non-relational.Source

Usage: (->MultiIntervalFD min max is)

Usage: (-distinctc x y* n*)

The real *individual* distinct constraint. x is a var that now is bound to a single value. y* were the non-singleton bound vars that existed at the construction of the constraint. n* is the set of singleton domain values that existed at the construction of the constraint. We use categorize to determine the current non-singleton bound vars and singleton vlaues. if x is in n* or the new singletons we have failed. If not we simply remove the value of x from the remaining non-singleton domains bound to vars.Source

Usage: (< u v)

A finite domain constraint. u must be less than v. u and v must eventually be given domains if vars.Source

Usage: (<= u v)

A finite domain constraint. u must be less than or equal to v. u and v must eventually be given domains if vars.Source

Usage: (== u v)

Usage: (> u v)

Usage: (>= u v)

A finite domain constraint. u must be greater than or equal to v. u and v must eventually be given domains if vars.Source

Usage: (bounded-listo l n)

Ensure that the list l never grows beyond bound n. n must have been assigned a domain.Source

Usage: (distinct v*)

A finite domain constraint that will guarantee that all vars that occur in v* will be unified with unique values. v* need not be ground. Any vars in v* should eventually be given a domain.Source

Usage: (distinctc v*)

The real distinct constraint. v* can be seq of logic vars and values or it can be a logic var itself. This constraint does not run until v* has become ground. When it has become ground we group v* into a set of logic vars and a sorted set of known singleton values. We then construct the individual constraint for each var.Source

Usage: (domain & args)

Construct a domain for assignment to a var. Arguments should be integers given in sorted order. domains may be more efficient than intervals when only a few values are possible.Source

Usage: (interval ub) (interval lb ub)

Construct an interval for an assignment to a var. intervals may be more efficient that the domain type when the range of possiblities is large.Source

Usage: (process-dom x dom domp)

If x is a var we update its domain. If it's an integer we check that it's a member of the given domain. dom is then new domain, it should have already been calculated from domp which was the previous domain.Source
