func-gen

func-gen can be used to generate unix text processing utilities from English text. It uses langchain to create javascript functions to process text, and it uses Extism and the JavaScript PDK to safely execute the code in a Wasm sandbox.

Install

Note: First you need to install Extism on your machine if you have not:

pip install --upgrade extism-func-gen

Run

# Need to set the OpenAI API key

# Create a func
func-gen count_vowels -d "Write a function that counts the number of vowels in an input string"

# Use a func
echo "hello world" | func-gen count_vowels
# 3


# List the funcs
func-gen --list
