Products that do what An HP 15C themed TUI RPN calculator does
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.

https://github.com/siraben/ti84-forth Hi HN! For the past year I've been getting into programming in Z80 assembly (especially for the TI-84+). More recently I've been learning about the Forth programming language and after a lot of searching online (in vain) for a Forth interpreter for the TI-84, I decided to write one myself. It's been fun demoing this to others, because it's a very unexpected use of a calculator. It's my largest project to date, and I'm interested to know what the HN community thinks, please feel free to critique my code! -- Ben

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Hi there, I tried to build a CLI tool to edit and visualize Excel/CSV files directly in the terminal, I called it "dss". I did it for fun to tweak spreadsheet formulas without leaving my terminal or opening heavy GUI apps. It is an interactive editor of sheets with charts and formula engine diretly in TUI. The formula engine is handmaded but I'd like to improve it. I copied a lot from my previous Datacmd project and from Termdash repo. Hoping to receive some feedback.

I've been building go-tui (https://go-tui.dev), a terminal UI framework for Go inspired by the templ framework for the web (https://templ.guide/). The syntax should be familiar to templ users and is quite different from other terminal frameworks like bubbletea. Instead of imperative widget manipulation or bubbletea's elm architecture, you write HTML-like syntax and Tailwind-style classes that can intermingle with regular Go code in a new .gsx filetype. Then you compile these files to type-safe Go using `tui generate`. At runtime there's a flexbox layout engine based…

Hi HN, I built a simple TUI for viewing and editing .md files in the terminal. More and more markdown files keep appearing in our projects, and I found myself needing a quick way to view(with syntax highlighting) and edit them without leaving the terminal, so I built this

This is my personal todo app, which I made a while back after the original https://xit.jotaen.net/ post. tuido is written in go, with the bubbletea tui framework. My daily workflow involves creating YYYY-MM-DD.md and taking notes, many of which are effectively low-level todos that fall below the threshold for more public or involved issue trackers. Problem was that these half-hazard todos weren't tracked at all. After seeing the [x]it spec, it seemed clear that a little tooling could fix this. I've been reasonably happy with it.
