Script BASIC for Java



--- Quote from: Peter Verhas ---ScriptBasic for Java is a BASIC interpreter that can be embedded into Java programs. With SB4J you can script your application (or let the users to script) in good old BASIC. You can start in the JVM an interpreter and execute for example

--- Code: Script BASIC ---PRINT "hello, I am BASIC"PRINT "\nthe numbers from 1 to 10 are\n"FOR I=1 to 10  PRINT I,"\n"NEXT I 
SB4J has all the BASIC language features, assignments, loops, subroutines, global and local variables and no GOTO statement. Seriously.

To embed the interpreter into your application you need to use SB4J as a dependency


and then use the JSR223 defined scripting interface or use the ScriptBasic native integration API.

The simplest way is to

ScriptBasic.getEngine().eval("PRINT \"hello world\"");
get an execution engine and eval() the program source. There are other possibilities. You can specify the file where the source code is, a to read the source code and there are even more advanced possibilities.

The BASIC language contains all the usual BASIC features, subroutines, local and global variables, conditional statements, loops and so on. (No GOTO!) Your host program can directly call subroutines, read and write global variables, provide methods implemented in Java to be called from BASIC code.

The interpreter can safely be integrated to applications as the BASIC programs can not access arbitrary objects and call Java methods at their will and there are other features that help controlling the scripts in the application. The language is a "no freak out" language, so you can put the programming possibility into the hands of users who would not ever touch Python, Groovy or some other programming language.

:o  KOOL!  8)

What Mike said.

But ... no GOTO? Really?

So I can no longer call my error handler by using GOTO Hell

Pity. :D

A true Android version of Script BASIC would be very doable using SBJ.


--- Quote from: Peter Verhas ---With the pull req made by Petr Pytelka the version 2.1.0 of jScriptBasic is released. It is a simple embeddable BASIC interpreter written in Java that you can use in applications to let users write simple scripts. This rel features multiple commands on a single line. Thanks Petr

Multiple statements per line is a major direction change IMHO.
