kixi.mallet

A Clojure library for interacting with Mallet. This is achieved in two ways currently:

1. A set of boot tasks wrapping Mallet's command-line utility
2. Macros for defining Mallet pipes in Clojure

The boot tasks are designed to be chained with other tasks, facilitating ad-hoc exploratory analysis.

Pipes

Pipes can be defined thusly:

(ns my.project
  (:require [kixi.mallet.pipe :refer [defpipe]]
            [clojure.string :as str]))

;; Pipes are defined as transducers:
;; map, mapcat, filter, etc
;; will all work as expected.

(defpipe DownCase
  (map (fn [instance]
         (update instance :data str/lower-case))))

The pipe can now be passed to Mallet as my.project.DownCase.

Note: the my.project namespace will need to be aot compiled.
