Open Source BASIC Interpreters - Page 2

TBasic is an implementation of a minimalist BASIC (based on the Tiny Basic specification but with a few significant additions) in the C++ language. It was written for fun, as a project to create a functional language interpreter from scratch and to be potentially used as a lightweight scripting language (it can either be used as a classic command line BASIC interpreter or as a class that allows a C++ programs to load and run basic programs, register custom basic commands and interact with basic variables).

"The Engine" is a game creation engine with built-in classic type BASIC interpreter (as known from old 8-bit computers), screen editor and full-screen editor, using OpenGL and SDL (currently POSIX only, but portable, in principle). It is aimed at game developers with little spare time, and tries to reduce program size with powerful commands that takes as much coding effort off the shoulders of the developer as humanly possible. The BASIC interpreter supports only labels, not line numbers, and the program is written with the built-in editor. Interpreter and graphics engine run in parallel, in separate threads, and hence interpreter speed is not an issue. The interpreter is not chiefly designed for speed, but for comfortable development. The editor and command screen use a custom 8 x 8 font on a 64x16 character text display. There are currently three switchable screens: Game screen, Output/Command screen, and Editor screen.

Vilegust - named for the codesmells that eventually come of such projects - is a basic-like interpreter/compiler project in vb.net that will eventually be self-compilable.

This is the windows version of XST Basic. Basic interpreter with C emitter written mostly in C. This also uses the irrlicht 3d library to make it much more capable than the DOS XST Basic 1. Enjoy,

This is an Open Sourced BASIC interpreter environment using PostgreSQL. It is focused on (1) Simple to program, (2) Powerful database statements, (3) UNIX shell friendly, (4) Business focused, (5) "Function" over "speed". This is *not* another VB implementation. Extensive language documentation is available.

A shell loosely based on the old Commodore and Tandy BASIC interpreters, with some small updating to modern computer systems

C64 like basic in java (pure not emulated)

nbasic - bytecode compiler+vm for middle level programming language, like basic. nbs - small and fast C-coded object orientated basic (compiler+vm) for embeded applications. Purpose: scripting support for C/C++ project.
