PuffinBASIC – A cross-platform modern BASIC interpreter written in Java

In plain words

PuffinBASIC is a cross-platform BASIC interpreter written in Java that allows users to run programs written in the classic BASIC language from the 1960s on modern systems. It conforms closely to GWBASIC and works by parsing source code using ANTLR4 grammar, generating an intermediate representation, and executing it at runtime. The tool is designed for developers interested in learning interpreter construction and bringing vintage BASIC programs into contemporary environments.

  ClifferBasic, a simple BASIC interpreter as a .NET REPL2024 · github.com · ▲23

  Ever since I got my first computer, a TI-99/4A, at age 13, I've been fascinated by programming languages. I've written a few interpreters, but this is the first time I've come back to the first language I've ever learned, BASIC. I started ClifferBasic as a way to shake out bugs and find feature weaknesses in another project I'm working on, Cliffer, which is a library for writing CLI applications in .NET using attributed program, but it's taken on a life of its own and has become a rather fun project. I'm planning to flesh out the BASIC implementation over the coming weeks, but I'd like…

  I've built a BASIC interpreter with DOS-like features for the web2021 · ▲8

  Hi everyone, When the pandemic started, I put QuickBASIC in front of my kids and could see them enjoy toying with writing some simple programs. Since then, I've been working on a side project to build a similar experience using modern technologies, with the goal of having a tool to teach the foundations of programming to (my own) kids. This is what EndBASIC is: is a retro-looking, BASIC interpreter with DOS-like features -- built for the web. The environment is designed to be minimalist in an attempt to reproduce the computing experience of the 1980s where the computers were simpler to…

  Bolt – A super-fast, statically-typed scripting language written in C2025 · github.com · ▲261

  I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

  Gsubpy, an interpreter for subset of Python, written in Go2023 · github.com · ▲65

  Recently, I write an interpreter for subset of Python using Go. I haven't seen source code of CPython, all is just written according to my understanding of Python so there may be some unusual things. Hope you can play fun with it. Any suggestion is welcome, glad to get some feedback.

  Talanoa▲345

  Hi 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…
