# Babel [![Build Status](https://travis-ci.org/quytelda/babel.svg?branch=master)](https://travis-ci.org/quytelda/babel)

Babel is a small utility written in Haskell that generates random sequences based on a context free grammar (CFG).  It can be used as a word generator or password generator.

For example:

```

$ babel -n 3 grammar.cfg

abcab

cba

bcabcba

```

In this example, grammar.cfg contains the following:

```

S -> A | B | C

A -> a B | a C | a

B -> b A | b C | b

C -> c A | c B | c

```

# What's Needed

In order to build babel, you must at least have the haskell compiler GHC 8.0+.  If you have Cabal installed, just run `cabal build` from the top level directory (where babel.cabal is located).  Otherwise, you can compile an executable by running `ghc -o babel --make -isrc src/Main.hs`.

Babel depends on the following haskell packages:

base >=4.7, containers >=0.5, random >=1.1, parsec >=3.1, split >= 0.2, cryptonite >= 0.17

All these packages are available in the repositories for most Linux distributions.
