Tutorial: How to use GF grammars from another program

This repository contains code examples to complement my blog post on embedding grammars. For general introduction, here's the intro of the blog post.

This post will show how to use GF grammars from an external program, and how to manipulate GF trees from that program. The topic is introduced in Lesson 7 of the tutorial, and I will cover parts that I find missing in the tutorial:

• Installation, other practicalities of the GF ecosystem
• Linguistically motivated example of tree manipulation
• Examples in both Haskell and Python (the examples are the same, so only knowing one is enough)

Advanced topics

These topics are discussed in the sequel blog post. To see full self-contained examples, each with their own README file, go to the following directories.

• Haskell bindings to the C runtime: advanced-pgf2 -- Minimal difference to the "basic" example
• GADTs in the generated Haskell code: advanced-gadts -- Significant difference, a new way of doing tree transformations
