my-basic

MY-BASIC is a tiny cross-platform easy extendable BASIC interpreter written in pure C with about 6000 lines of source code. Its grammar is similar to structured BASIC in early era, but without line number. It is aimed to be either an embeddable scripting language or a standalone interpreter. The core is pretty light; all in a C source file and an associated header file. You can combine MY-BASIC with an existing C/C++/Objective-C project easily, scripting driven can make your projects more powerful, elegant and neat.

Main features

Written in clean ANSI C, source code portable

Case-insensitive tokens
Integer/float point/string/boolean/array data types support
IF-THEN-ELSE support
FOR-TO-STEP-NEXT/WHILE-WEND/DO-UNTIL support
GOTO/GOSUB-RETURN support
Numeric functions
String functions
Easy to embed into C/C++/Objective-C projects
High expansibility, easy to use APIs, easy to write customized scripting interfaces

Installation

Use standalone interpreter binary

This repository contains precompiled binaries for Win32 and MacOS, it's efficient to download it and have a first impressive playground.

To compile an interpreter binary for your own platform, please see the steps as follow.

Retrieve core and shell folders
Setup your compile toolchain configuration
Use your compiler to process core/my_basic.c and shell/main.c, both require including core/my_basic.h

Combine with exist projects

MY-BASIC is cleanly written in a single C source file and an associated header file. Just copy my_basic.c and my_basic.h to your project folder and add them to a build configuration.

For more details about using MY-BASIC with exist projects, please see MY-BASIC Quick Reference.
