A Lisp Programmer Living in Python-Land: The Hy Programming Language
A Lisp Programmer Living in Python-Land: The Hy Programming Language
All examples are provided in both Hy and Python
About the Book
Github repository update May 25, 2023:
- Updated all code examples to use latest Hy language version 0.26.0
- Added a chapter with examples using Open AI GPT-3.5 APIs
- 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
- Relational databases
- Web app development
- Web scraping
- Using the Bing 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
- OpenAI GPT-3.5 APIs
- LangChain
