Codemancer

Codemancer is a command line program that uses OpenAI's API to generate code based on a given prompt and input file. It is installable via npm and requires an OpenAI API key.

Installation

npm install -g codemancer

Usage

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

export OPENAI_API_KEY=your_api_key_here

⚠️ codemancer is most useful when using GPT-4, and by will use it by default. If you do not have access yet, you can specify the -m "gpt-3.5-turbo" argument, but code generations will be much less reliable.

Reading and writing to the same file

Modify a file in-place based on a prompt, useful for iterating on functionality, addressing review comments, or refactoring.

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

This command will read the content of the input file and send it along with the prompt to the OpenAI API. The generated code will be displayed in the terminal and, after confirmation, written back to the same file.

Writing to a different file

Useful for generating a new file with similar functionality, generating readmes, or interface definitions (e.g. rpc).

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

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"
