#yammat

Yet Another MateMAT

##Introduction

This project aims to be an implementation for a trust based POS for hackerspaces.

##Dependencies

###External dependencies

In order to build yammat you need the packages `cabal-install`, `ghc`, `libmagick++-dev` and `postgresql`. Furthermore you need the Haskell packages `alex` and `happy`. To install these enter `cabal install alex happy` into your command line.

###Internal dependencies

Before installing the internal dependencies it is best practice to put the project into a sandbox with `cabal sandbox init`.

All internal dependencies are in the file `yammat.cabal` and will be installed automagically with the command `cabal install --only-dependencies`.

##Building

To build this project enter `cabal configure && cabal build yammat` into your command line

##Deployment

Copy or link the executable `dist/build/yammat/yammat` to your desired run location alongside with the folders `static` and `config`. The Folders should be copied, or you will get problems with your git pulls.

##Configuration

Check the configuration File `config/settings.yml`. Create Postgresql Databases according to these settings.

##Lift-Off

Run `./yammat config/settings.yml` in your desired run location. Finally point a reverse-proxy (something like nginx) at `http://localhost:3000` or any other port you configured in `config/settings.yml`.

For better control You can wrap an init script around this. How to do this is described [in my blog][blog].
