Hi B4A team,

I'm a new user to Basic4Android and think it's a great tool to develop Android applications. I'm just getting my arms around Java programming but have been a Basic programmer for over 40 years. I manage the open source project for the ScriptBasic ANSI/ISO C version of the scripting engine. It was written by Peter Verhas from Budapest Hungary.

Peter has recently released a Java version of ScriptBasic that I think would be a nice enhancement to Basic4Android as an embedded traditional typeless Basic scripting engine. I don't think it is going to be much of an effort to wrap SB4J in a library for Basic4Android. I just need some help from others that have gone down this road before. I have been playing with SB4J at the command line and I would like to get it working with B4A if all possible.

FOR x = 1 TO 10
  a[x] = x
NEXT x

FOR z = 1 TO 10
  PRINT a[z],"\n"
NEXT z

Embedding SB4J (project site)

I have attached the SB4J (ScriptBasic for Java) JAR file to give this a try and hopefully get integrated into Basic4Android.

Looks great and very feature rich.

Peter's goal with SB4J is a simplistic embeddable scripting engine that is easy to extend based on need. He isn't actively developing for the Android platform but I thought I would give it a try with Basic4Android.

No need to recreate the wheel and I'm going to use B4Script with my Android projects.

Thanks for the link and libraries.

I have BasicIDE and B4Script compiled and working on my Samsung Galaxy Tab 2 10.1 tablet. Are these libraries open source? I can see the class files in the JAR but they aren't in a text file format.

I would like to contribute to this project but source access is a must.

BasicLibIDE is not open source.

I thiink you did a great job with BasicIDE and having a ton of fun playing with it.

Peter Verhas is expanding on the string aspect of SB4J as the USE/METHOD syntax still sees Java strings as objects. Once the Java API is more accessible in a Basic like way, I will give the Basic4Android library effort another try. SB4J is a light weight embeddable scripting engine and not headed down BasicIDE's path.
