clj-foundation.pipe
A Unix pipe function for Clojure that is implemented by converting regular Clojure functions into transducers over the input.
Input can be any container or a simple type. For a container, the output will be the same type as the input. If the input is a simple type, it will be wrapped in a vector before being processed and the result will be a vector. Supported container types include Map, List, Vector, and Set.
fns may include any of the following:
-
An arity 1 function is treated as a mapcat function with the following relaxed rules: If it returns a value of a simple type, the value is appended to the output. A nil result is considered an empty result. Otherwise, mapcat semantics are followed. e.g.: if you want the result to be a collection of collections, the sub-collection must first be wrapped in another collection so the sub-collection itself will be concatinated onto the result.
-
An arity 2 function is treated as a reducing function where the initial two collection elements specify the initial two elements in the reduction. The reducer supports the 'reduced' function in the standard library so that a single input collection can produce multiple reduced outputs.
-
A vector containing an arity 2 function and a second value treats the function as a reducer and the second value as the initial value in the reduction.
The input is processed through fns, a single element at a time, without creating intermediate collections, in the order in which fns are specified.
