# Bismuth

[![Build Status](https://travis-ci.org/justinwoo/purescript-bismuth.svg?branch=master)](https://travis-ci.org/justinwoo/purescript-bismuth)

A library for generating flow type signatures for direct interop between PureScript and Flow. Similar to [OhYes](https://github.com/justinwoo/purescript-ohyes)

## Tl;dr

```hs

type A =

  { a :: Number

  , b :: String

  , c :: { d :: String }

  , e :: Array String

  , f :: Nullable String

  , g :: Number -> Number -> Number

  , h :: Fn2 Number Number Number

  , i :: Fn2 Number (Fn2 Number Number Number) Number

  , l :: Foreign

  , k :: StrMap Number

  }

type VariantTest = Variant

  ( a :: String

  , b :: Number

  , c :: Boolean

  )

```

```js

//@flow

export type A = {

  a: number,

  b: string,

  c: { d: string },

  e: string[],

  f: string | null,

  g: (a: number) => (a: number) => number,

  h: (a: number, b: number) => number,

  i: (a: number, b: (a: number, b: number) => number) => number,

  k: { [key: string]: number },

  l: any

};

export type VariantTest =

  | { type: "a", value: string }

  | { type: "b", value: number }

  | { type: "c", value: boolean };

```
