pos2tracery
===========

[![npm version](https://badge.fury.io/js/pos2tracery.svg)](https://badge.fury.io/js/pos2tracery)

> pos2tracery is a tool stemming from my
> [NaNoGenMo 2017 Artbook Project](http://jkirchartz.com/NaNoGenMo/2017/) and
> modified with behaviors from the [NaNoGenMo 2018 Wink
> Project](http://jkirchartz.com/NaNoGenMo/2018/) it uses the [Wink POS
> Tagger](https://winkjs.org/wink-pos-tagger/) which uses the transformation
> based learning (TBL) approach to create tracery grammars to take sentence forms
> from a corpus, but replace the parts of speech within them with other parts of
> speech from throughout the corpus. It is aware of contractions and punction;
> and creates tracery's default english modifiers.

## MODULE USAGE
pos2tracery can also be used inside of your node projects. Each option is set by using the long-form version of the CLI option
The only change is that since `delete` is a reserved word in Javascript the function is called `del`


    const p2t = require('pos2tracery');

    let merged = p2t.merge({
      inputA: p2t.del({
                input: "./grammar_A.json",
                toss: "story"
              }),
      inputB: p2t.del({
                input: "./grammar_B.json",
                keep: "story"
              })
      });

      p2t.generate({
        input: merged,
        modifiers: true
      });
