Predicates are functions that takes as a param a value and return true if the value matches predicate, false otherwise and nil if comparison can't be done. Predicate functions can be expressed via a query language represented with vector. This namespace is about managing that language

apply-query clj/s

(apply-query pred d)

(apply-query reg pred d)

Accepts pred query vector, translates it with reg and applies it to d Returns response from predicate or nil if application couldn't be done

apply-query-detailed clj/s

(apply-query-detailed pred d)

(apply-query-detailed reg pred d)

Same as apply-query, but in case of an error it returns a map with more detailed information

is-predicate? clj/s

(is-predicate? reg pred)

pred-lang-schema clj/s

Predicate vector language consists of :keyword represnting the name of predicate and zero or more parameters for that predicate See predicate language

pred-registry-schema clj/s

Predicate registry consists of keyword keys representing predicate name with map as a value, containing an implementation of the predicate under :pred-fn and metadata for the predicate

predicate-lang->pred-fn-detailed clj/s

(predicate-lang->pred-fn-detailed pred)

(predicate-lang->pred-fn-detailed reg pred)

Turns predicate query language into a function

predicate-lang->predicate-fn clj/s

(predicate-lang->predicate-fn reg pred)

Translates pred vector language into a function. Expects reg map containing predicate name as keys with values containing a function under :pred-fn

predicate-validation clj/s

(predicate-validation reg pred)

predicates-registry clj/s

Default predicates language registry. See more

registry-value clj/s
