An HP 15C themed TUI RPN calculator
Recently, I found a long desired framework that treats the terminal via a DOM/CSS approach named Textual [https://textual.textualize.io]. In order to explore this framework I started developing a terminal based TUI RPN (styled in the aesthetic of a classic HP 15C pocket) calculator. So far this TUI RPN calculator has classic HP styled buttons, LCD display and some of the basic math operations. This is very much a W.I.P. Any engagement welcome.

I made a web-based notepad with a built in unit calculator2022 · numpad.io · ▲488I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/
Trogon – An automatic TUI for command line apps2023 · github.com · ▲248Hi HN, Trogon is a project to generate a TUI for command line apps. It presents the arguments, options, and switches as a form. Editing the form generates a command line, which you can then run with a keypress. I'm a lover of the command line. But I can recall only a fraction of the switches for most commands I use. I would love it if there was a TUI available for most commands. Trogon currently works with Python and the Click library, but I would like it to cover more of the Python ecosystem and also generate TUIs for apps not written in Python. More information in the repository. Let me…
Figr.app – a multi-user, notepad style calculator (desktop app)2022 · figr.app · ▲275Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator: https://news.ycombinator.com/item?id=31817997 After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations. You can find the download links below:…
- TATattoy – a text-based terminal compositor2025 · tattoy.sh · ▲200
Whereas this is mostly a terminal eye-candy project to get you street cred, it does have some serious aspects. Firstly it solves the age-old problem of low-contrast text, like when you `ls` a broken symlink and the red background colour is too near your current theme's foreground colour. Tattoy solves this by using none other than the web's WCAG 2.1 contrast algorithm for accessible text. Secondly, an explicit design goal is that Tattoy should be able to polyfill new terminal protocols, the `xwayland` of the TTY if you will. Say if we want to experiment with completely deprecating ANSI…

A modular Python TUI framework with a fast and pretty markup language2022 · github.com · ▲114PyTermGUI is a highly modular framework offering most of the features one would expect from a GUI library, such as a mature and open Widget API, animations, mouse support and other goodies, right inside the terminal! The markup language is another great feature of the library, and is used by practically all elements of it. It is based on Rich's implementation, but uses a more concise and easier to humanly parse syntax, while being over 10 times faster at parsing due to a long list of optimizations. There is a full Window Manager API included as well, allowing the user to move, resize and…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
