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 tool by Andrew Gallant.

At present morela is in early development phase and highly unstable.

Installation

morela requires GraphViz.

Stack

Install the Stack 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

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.
