EndBASIC is an interpreter for a BASIC-like language and is inspired by Amstrad's Locomotive BASIC 1.1 and Microsoft's QuickBASIC 4.5. Like the former, EndBASIC intends to provide an interactive environment that seamlessly merges coding with immediate visual feedback. Like the latter, EndBASIC offers higher-level programming constructs and strong typing.

EndBASIC offers a simplified and restricted environment to learn the foundations of programming and focuses on features that can quickly reward the programmer. These features include things like a built-in text editor, commands to manipulate the screen, and commands to interact with the hardware of a Raspberry Pi. Implementing this kind of features has priority over others such as performance or a much richer language.

EndBASIC is written in Rust and runs both on the web and locally on a variety of operating systems and platforms, including macOS, Windows, and Linux.

EndBASIC is free software under the Apache 2.0 License.

The latest version of EndBASIC is 0.6.0 and was released on 2021-02-19.

Open EndBASIC in your browser by visiting: https://endbasic.jmmv.dev/

This should work on all major desktop browsers and on iOS. Unfortunately, there are known issues on Android at the moment.

The web interpreter runs fully locally: any programs you write are persisted in your browser's local storage and not uploaded to the cloud.

Visit the release page to download prebuilt binaries. Once downloaded, unpack the archive and run the endbasic binary to get started.

Of course, you can also build and install EndBASIC from source by running the following command (assuming you have a Rust toolchain installed): cargo install endbasic.

Sample code:

• cli/examples contains the EndBASIC demo programs. These are built into the interpreter and can be run with a command like LOAD "DEMOS:/TOUR.BAS": RUN.
• core/examples and std/examples demonstrate how to embed the EndBASIC interpreter into your own programs.

EndBASIC started as part of my desire to teach programming to my own kids. I remember learning programming on an old Amstrad CPC 6128: the experience was unique in the sense that every command had immediate effect. Changing colors, drawing on the screen, or playing sounds were just a few keystrokes away after booting the computer, without the need to deal with separate editors and terminals. I've noticed a similar excitement in my kids when showing this to them via an emulator, so I thought I would replicate this in a more modern fashion. And here we are.

Because of this inspiration, EndBASIC's name stands for "E. and D.'s BASIC" following my kids first name initials.
