#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 exe: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.
