GPTDiff

Send your entire codebase to gpt and get a changeset.

cd myproject
gptdiff 'add hover effects to the buttons'

Generates a prompt.txt file that you can copy and paste into a large context gpt to have a conversation with suggested changes. You can also invoke the API and try to directly apply the patch (this often doesn't work).

Installation

Requires Python. Clone this repo and run:

It requires tiktoken to count gpt4o tokens.

pip install tiktoken

Development install (no pip package yet)

python setup.py install

Configuration

To call openai from the command line, you need to set the OPENAI_API_KEY environment variable:

export OPENAI_API_KEY='your-openai-api-key'

OpenAI will not be called unless you specify --call or --apply

Prevent files being appended to the prompt by adding them to .gitignore or .gptignore

Usage

After installing the package, you can use the gptdiff command in your terminal. cd into your codebase and run:

gptdiff '<user_prompt>'

any files that are included in .gitignore are ignored when generating prompt.txt.

Specifying Additional Files or Directories

You can specify additional files or directories to include in the prompt by adding them as arguments to the gptdiff command. If no additional files or directories are specified, the tool will default to using the current working directory.

Example usage:

gptdiff 'make this change' src test

Autopatch with --apply

You can also call openai and automatically apply the generated git diff with the --apply flag:

gptdiff '<user_prompt>' --apply

This often generates incorrect diffs that need to be manually merged.

Dependencies

The gptdiff package depends on the argparse and openai packages.
