BAScript - Simple scripting interpreter

[Ñuño_Martínez]

I've released BAScript 2.3.β.

BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript.

This version fixes some (quite silly) bugs and adds support for fixed-point number (less accurate than floating-point ones (Real) but enough for most cases) and a new language similar to BASIC and Lua named Kor, so there are three supported languages: Kor, BriefC y BAScript.

You can download from here.

Comments and suggestions are welcome.

Hello, very nice project!
I download it, compilation is OK with Fpc 3.2.2 (Fpc trunk 3.3.1 has errors).
It should be very good to have an example of embedding the engine in an host program, calling host functions.

Very interesting.

Thanks.

Thanks for the comments

Can you post the error messages?

Besides the basrun app, documentation has a tutorial.  It's in file ~/docs/lib/howtos.html.

Where can I learn more about these languages?

We need Visual-Learning. This year we are AI very good, that reason : How to Learn together Secondary script for "Lazarus?
 E.g (InnoSetup-Script, other, Clojure or BasScript, LUA-script)
The main problem for many many programmer/s:
C:Q1= How to Learning only visual-Learning.?. because (for algorithmic, old method Learning , Bytes, Octal, TstringList, the Sort Method-Learning, ) for these, compilator Lazarus is very very good.
C:Q2=How to increase Visual Learning for BasScript?
C:Q3=Perhaps how to increase Visual Learning for LAzarus? . . .

Interesting, but I stick with Python for scripting (or Pascal Script)

Ok.  I take note (Ticket #3) and I'll fix it for the stable version.

Thanks.

As you need.  Actually BAScript doesn't aim to replace them.  It started as a pet project to learn myself then I found it would be useful for smeone else.

[Ñuño_Martínez]

Where can I learn more about these languages?

There are documentation in the ~/docs/language subdirectory.  Also there are a few examples in the bin directory.

[Ñuño_Martínez]

So after checking the feedback and testing while updating my small IDE (that uses it) I've fixed a bunch of stuff so I decided to release it as stable.  Enjoy.
