# FParsec-Pipes

This library is an extension to the FParsec library (http://www.quanttec.com/fparsec/).

Please see the [project page](http://rspeele.github.io/FParsec-Pipes/)

or read the [intro](http://rspeele.github.io/FParsec-Pipes/Intro.html).

FParsec-Pipes does not define new parsers.

Instead, its goal is to make it easier and more readable to define your own parsers.

## Why should I care? Show me some code I can write with this.

```fsharp

let pdatetime =

    let digits (count : int) = %% +.(qty.[count] * digit) -|> (String >> Int32.Parse)

    %% +.digits 4 -- '-' -- +.digits 2 -- '-' -- +.digits 2 -- 'T'

    -- +.digits 2 -- ':' -- +.digits 2 -- ':' -- +.digits 2

    -|> fun yyyy mm dd h m s ->

        new DateTime(yyyy, mm, dd, h, m, s)

```
