Github repository update May 25, 2023:

Updated all code examples to use latest Hy language version 1.1.0
Added a chapter with examples using Open AI GPT-5, Google Gemini APIs and using local models with Ollama
Added a chapter using the LangChain library

While this is a book on the Hy Lisp language.

In addition to being a tutorial and cookbook on using the Hy language, longer examples explore a variety of different applications and tools. The current structure of the book is:

Introduction to the Hy Language
Why use Lisp? Advantages of bottom up development using macros and closures
Open AI GPT-5, Google Gemini APIs and using local models with Ollama
Relational databases
Web app development
Web scraping
Using the Brave search APIs
Accessing semantic web and linked data sources like Wikipedia, DBpedia, and Wikidata
Automatically constructing Knowledge Graphs from text documents, semantic web and linked data
Deep Learning (predictive model from spreadsheet data and a LSTM-based English text language model)
Natural Language Processing (NLP) using Deep Learning
Creating Knowledge Graphs from text data
Hy language implementation of the author's Knowledge Graph Navigator project
LangChain
