CodeGenPT

Autogenerate files or entire projects using ChatGPT API.

Installation

pip install codegenpt

Usage

CodeGenPT looks for .codegenpt files and generate files using its instructions.

Generating individual files

Example: hello_world.py.codegenpt

Create a hello world program

Then:

$ codegenpt helloworld.py.codegenpt
⏳ Generating file: helloworld.py
🍺 File generated: helloworld.py
🍻 Success

Will generate a file named helloworld.py:

print("hello world");

The actual content of the file will be generated by ChatGPT, so it will vary at each run. You can use codegenpt -R . to recursively look for all .codegenpt files and generate them.

Generate entire directories or projects

You can create entire directories or projects using a .dir.codegenpt file. Example: tictactoe.dir.codegenpt

Create a tic-tac-toe game using html, js and css.

Then:

$ codegenpt tic-tac-toe.dir.codegenpt
⏳ Generating directory: tic-tac-toe
🍺 File generated: tic-tac-toe/style.css
🍺 File generated: tic-tac-toe/index.html
🍺 File generated: tic-tac-toe/game.js
🍻 Success

Will create a folder called tic-tac-toe and generate all needed files.

Setup

CodeGenPT expects an environment variable called OPEN_API_KEY.

1. Get an Open AI API Key
2. Add the key to your OPEN_API_KEY environment variable:

• If you use bash:

  echo 'export OPENAI_API_KEY={your api key}' >> ~/.bash_profile && source ~/.bash_profile

• If yu use zsh:

  echo 'export OPENAI_API_KEY={your api key}' >> ~/.zshenv && source ~/.zshenv
  

Commands

Commands are special instructions you can use to instruct the generation process.

All codegenpt commands are placed in a single line in the format:

@command_name args...

@include

Includes one or more files on the context. Included files can be referenced using @filename.ext in the generation instructions

Example:

names.txt:

Diego
Alberto
Daniel

random_name.js.codegenpt:

@include assets/names.txt

Read @names.txt and write a function that returns one of the names

random_name.js:

function getRandomName() {
  const names = [
    'Diego',
    'Alberto',
    'Daniel'
  ];

  const randomIndex = Math.floor(Math.random() * names.length);

  return names[randomIndex];
}
