'''fptools''' is a library of general-purpose procedures for [functional programming] in Tcl 8.5, Tcl 8.6 and [Jim Tcl]. The library implements [Commands pipe%|%command pipelines], [pattern matching] on lists, [range], a Clojure-like `recur` that uses [tailcall] when available and a number of list transformations. Each procedure is described in a comment that directly precedes its declaration. You can download the library with [wiki-reaper]: `wiki-reaper 41349 0 | tee fptools-0.1.tm` If you fix a bug please increment the patch level in `::fptools::version`. **Code** ====== ====== **Discussion** **See also** <>Functional Programming | Jim Package
