Conditions used in annotations.

A condition is a function that takes a value and an optional context map as parameters and returns a result map. The context map contains extra data that is passed as input. The result map will be empty if the conditiong is satisfied (indicating success). Otherwise, it will have at least one of the keys :warnings and :errors. These keys will map to a sequence of warning and error message strings respectively.

and clj

(and cnd & cnds)

Forms a compound condition that evaluates the given conditions one at a time, from left to right. If a condition returns an error or warning result, and returns that value and doesn't evaluate any of the other conditions, otherwise it returns the result of the last condition.

coll-length clj

(coll-length opts)

(coll-length opts) returns a condition to check if length of a collection matches certain criteria. opts is a map specifying the match criteria and can have the following keys:

:lt - collection length must be less than the value of this key :le - collection length must be less than or equal to the value of this key :gt - collection length must be greater than the value of this key :ge - collection length must be greater than or equal to the value of this key :eq - collection length must be equal to the value of this key :ne - collection length must not be equal to the value of this key

or clj

(or cnd & cnds)

Forms a compound condition that evaluates conditions one at a time, from left to right. If a condition returns a success value, or returns that value and doesn't evaluate any of the other conditions, otherwise it returns the value of the last condition

regex-match? clj

(regex-match? re)

(regex-match re) returns a condition that takes a string s as input and checks if it matches the regular expression re

seq-length clj

(seq-length {:keys [lt le gt ge eq ne]} l name)

string-length clj

(string-length opts)

(string-length opts) returns a condition to check if length of a string matches certain criteria. opts is a map specifying the match criteria and can have the following keys:

:lt - string length must be less than the value of this key :le - string length must be less than or equal to the value of this key :gt - string length must be greater than the value of this key :ge - string length must be greater than or equal to the value of this key :eq - string length must be equal to the value of this key :ne - string length must not be equal to the value of this key

unique-attribute? clj

(unique-attribute? k)

(unique-attribute k) returns a condition that takes a sequence of maps ms and ensure that the value of attribute k is unique across all the maps.
