Babble

Package babble implements a finite Markov chain sentence generator, inspired by Jeremy Singer-Vine's excellent markovify for Python. Eric Bower's sentences package is used for sentence extraction.

Usage

package main

import (
        "fmt"
        "io/ioutil"

        "github.com/ragnar-johannsson/babble"
)

func main() {
        // The Problems of Philosophy by Bertrand Russell
        b, _ := ioutil.ReadFile("./texts/pg5827.txt")
        t := babble.NewTextModel(string(b), babble.DEFAULT_STATE_SIZE)

        fmt.Println(t.MakeShortSentence(140))
        // Our nature is the characteristic of the universe, we have discovered so far.
}
