README
`morela` transforms a plain text description of relational database schema
(including tables, their attributes and integrity constraints) into a visual
diagram modeling the description. The visualization is produced
using GraphViz.
This project is based on the [`erd`](http://github.com/BurntSushi/erd) tool
by Andrew Gallant.
At present `morela` is in early development phase and highly unstable.
### Installation
`morela` requires [GraphViz](http://www.graphviz.org/download/).
#### Stack
Install the [Stack](http://docs.haskellstack.org/en/stable/README/) build tool,
and build from source:
git clone git://github.com/kukimik/morela
cd morela
stack install
`stack install` will put the binary into Stack's standard binary
installation path. Unless you've overridden it, that's `~/.local/bin`
on Unix and OS X, `%APPDATA%\local\bin` on Windows.
### Usage
```bash
morela [-f|--output-format FORMAT] < input.mrl > output_file
```
Available output formats are: dot,eps,fig,gif,jpeg,pdf,png,ps,ps2,svg,svgz,tiff,webp,sql.
