Why are existing script interpreters so complex? Why is it so difficult to integrate with them? Why not try MY-BASIC today!
Introduction
MY-BASIC is a tiny cross-platform easy extendable BASIC interpreter written in pure C with about 7000 lines of source code. Its grammar is similar to structured BASIC. 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, etc. project easily, scripting driven can make your projects more powerful, elegant and neat.
Main features
- It is free
- Written in clean ANSI C, source code portable
- With most common BASIC syntax
- Small (within memory usage less than 128KB) and fast
- Case-insensitive tokenization
- Integer, float point, string, boolean, user defined data types with array support, etc.
- Structured
IF-THEN-ELSEIF-ELSE-ENDIFsupport - Structured
FOR-TO-STEP-NEXT/WHILE-WEND/DO-UNTILsupport - Structured user costomized sub routine definition by
DEF/ENDDEFsupport GOTO/GOSUB-RETURNsupport- Standard numeric functions
- Standard string functions
- Debug APIs
- High expansibility, easy to use APIs, easy to write customized scripting interfaces
- It's able to use it as a standalone interpreter, or integrate it with existing C, C++, Objective-C, etc. projects
- It's able to learn how to build an interpreter from scratch from MY-BASIC
- It's able to build your own dialect based on MY-BASIC
- More features/modules under developing

Installation
Use standalone interpreter binary
This repository contains precompiled binaries for Windows and OS X, it's efficient to download it and have a first impressive playground.
To compile an interpreter binary for your own platform, please follow the steps.
- Retrieve at least
coreandshellfolders for minimum build - Setup your compile toolchain configuration
- Use your compiler to compile
core/my_basic.candshell/main.c, includingcore/my_basic.his required for both source files, then link up your own executable
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.
You can definitely link with MY-BASIC as a lib as well.
For more details about using MY-BASIC when it's already integrated with exist projects, please see MY-BASIC Quick Reference.
