    Github Copilot is a great tool for leveraging GPTs while coding, but I find that it is too “open loop” for more complex tasks that require Q&A, feedback to guide it in a particular direction, iteration on code execution errors, etc. There is a large class of tasks that are better accomplished in an iterative, stateful chat-like interface. I have been experimenting with a local command line chat interface to GPT-4 and my mind was blown once again a few days ago when I copied documentation for a pretty involved API into the model context and managed to chat-guide GPT-4 to implement the API in…

    Hi HN community, A few friends of mine and I built Tym – a small VS Code extension that makes it easy to share code snippets and get feedback from your teammates. With Tym, you can select a snippet of code and add a question or terminal dump right from the right-click menu. Your teammates can then easily browse your code in a web-based version of VSCode, even if you have uncommitted changes (we make a commit to a hidden git reference in your repo). We made Tym so we don’t have to go to Github and find lines every time we want to share a piece of code. With Tym, you can stay in VS Code and…

    ChatIDE is a sort of a DIY Github copilot X. Launch ChatIDE with a `Cmd + Shift + i`. You bring your own OpenAI api key. You can set the system prompt, temperature, and max tokens in the extension settings. The extension is currently not aware of any of the files in your project, although that might be cool to add later. Use it just like you would use ChatGPT in the browser. Feedback and contributions more than welcome.

    Definition Stack is a new vscode extension I have just released. It is a reading tool for Javascript and Typescript. It is available in the extension marketplace. You just click in a function in any source code, execute a command, and a new tab opens next to the original. That tab has a "block" which contains a copy of the function you clicked in. In that code every word (symbol) that has a definition is highlighted. If you click on a higlighted word a new block opens above the original which contains the source code of the definition for that word. You can click in that block and repeat to…

    Hi everyone! At Fluxon, we found that we were't happy with existing solutions for collaborative coding with engineering candidates in our technical interviews. So we built OpenBracket.net—a simple code editor with no setup or log in needed—just share the link and start coding together. Our first version is now available for anyone to use. We’d love some feedback. Thanks!
