Eco is a prototype editor for editing composed languages. It is not feature complete, it is not intended for production, and it does have bugs. Eco is distributed under a BSD/MIT license.
At a minimum you will need to install:
- Python 3 https://www.python.org/download/
- PyQt5 http://www.riverbankcomputing.co.uk/software/pyqt/download5
- Py http://py.readthedocs.io/en/latest/install.html
On Unix machines, you can reasonably expect your distribution to have packages for Python and PyQt. You may need to install Py using Pip or similar (see the link above).
If you wish to see visualisations of parse trees, you may optionally install:
- GraphViz http://www.graphviz.org/Download.php
- PyDot https://code.google.com/p/pydot/
- Pygame https://www.pygame.org/
To run Eco, use the bin/eco file:
$ bin/eco
A small tutorial to get you started with the basics of Eco can be found here.
If you are having trouble running Eco on the Windows Subsystem running Ubuntu, follow these instructions:
# Install Python3
sudo apt-get install python3 libxkbcommon-x11-0
# Install dependencies via pip
python3 -m pip install --user PyQt5 py
# Optional dependencies to visualise parse trees
sudo apt-get install graphviz
python3 -m pip install --user pydot pygame
