Guile Pipe

Guile pipe macros for functional chaining, similar to the UNIX pipe "|" operator.

Provides identical functionality to Clojure's function threading macros (-> and ->>).

Requirements

Guile is required.

Installation

Run sudo ./install to install pipe to Guile's site-dir folder.

Usage

Import pipe with

(use-modules (pipe))

You can then use the thread-first -> and thread-last ->> macros like so:

guile> (-> 100 (/ 10) (/ 5))
2

guile> (->> 100 (/ 10) (/ 5))
50

Thread first macro ->

The first s-expression will be inserted as the first argument of the next s-expesssion.

Example: (-> 100 (/ 10) (/ 5)) becomes (/ (/ 100 10) 5)

Thread last macro ->>

The first s-expression will be inserted as the last argument of the next s-expesssion.

Example: (->> 100 (/ 10) (/ 5)) becomes (/ 5 (/ 10 100))
