# Hooky - an LD_PRELOAD hooker

[![Documentation](https://docs.rs/hooky/badge.svg)](https://docs.rs/hooky/*/hooky/)

This crate allows convenient `LD_PRELOAD`-style hooking of functions.

## Getting started

1. Go into `examples/yesterday` and type:

       $ cargo build

2. Check the current date:

       $ /bin/bash -c "date"
       Tue Apr 25 18:19:57 CEST 2017

3. Check the date again:

       $ LD_PRELOAD=./target/debug/libyesterday.so /bin/bash -c "date"
       Mon Apr 24 18:20:25 CEST 2017

It seems like we went back in time!
