Recently we posted a quick introduction to ChaiScript on YouTube. Check it out, tell us what you think.

ChaiScript 1.3 was just released on googlecode.

Changes:

• Allow floating point numbers without a leading 0.
• Fix dispatch of functions that take boost::shared_ptr parameters.
• Add "use" function for loading ChaiScript files from within ChaiScript files.
• Double performance of tightloops by speeding up operator dispatches.
• Prevent the use of reserved words as function and object names.
• Fix error messages for failed "clone" calls.

The ChaiScript 1.2 release was just tagged and released on googlecode. 1.2 represents a significant performance increase for ChaiScript, with long running scripts running up to 3x faster than previously.

It is functionally the same as 1.2, so it is currently planned to be a source only release.

1.1 of ChaiScript was just posted.

This release includes many enhancements to the C++ API. The code required to register new functions and types has been greatly simplified. Don't worry, porting existing 1.0 code to the new API should be simple.

Example:

register_function(chai.get_eval_engine(), &MyClass::method, "method");

becomes:

chai.add(fun(&MyClass::function), "method");
