Code with GPT-4 from your command line

codemancer is a command line tool that uses the OpenAI API to generate code based on a given prompt and input file. It can change code in-place or create brand new files.

You can use it as a versatile and efficient AI-powered programming assistant that simplifies code generation, streamlines development tasks, and boosts productivity.

💫 You can now try codemancer with our own (free but rate-limited) OpenAI proxy, with GPT-4 enabled.

Installation

npm install -g codemancer

Usage

To use codemancer with your own OpenAI API key, you need to set the OPENAI_API_KEY environment variable.

export OPENAI_API_KEY=your_api_key_here

codemancer works best using GPT-4, and will use it by default. If you do not have access and receive a 404, you can use the GPT-3.5 model instead via -m "gpt-3.5-turbo", but code generations will be much less reliable.

Reading and writing to the same file

codemancer -i input_file_path -p "break the /recipe/<id> route into /recipe/<id>/info and /recipe/<id>/image"

Reading and writing to a different file

codemancer -i input_file_path -o output_file_path -p "extract inlined types into interfaces in a separate file"

Writing from prompt to file

codemancer -o output_file_path -p "I need an AppleScript to wipe Safari history on restart"

Simple prompting

codemancer -p "what's a bulletproof regex for validating emails"

Customizing model and temperature

codemancer -i input_file_path -m gpt-3.5-turbo -t 0.5 -p "change all variable names to obscure animals"
