GF web-based syntax editor
John J. Camilleri
January 2013
A tool for building and manipulating abstract syntax trees in GF. This is meant as improved replacement of the old syntax editor.
Example usage
If you want to use the tool in your own application, everything you need in the source
files editor.html and editor_online.js. Contact the GF developer mailing list
if you have any problems.
