Freeode 0.4.0 is released!

Written for Freeode by Eike on 2010-07-07

This release brings a new architecture: Siml is now a real object oriented language, with static typing. The syntax is now whitespace sensitive: indentation creates blocks, like in Python.

The release brings no real new features, but it is a good base for further development.

The code execution at compile time, is now considered to be macro execution, similar to Scheme or D. At compile time Siml classes are now Python classes. This implies that Siml instances are now regular Python objects. This makes the code more simple but somewhat quirky, because more advanced features of Python have to be used. (Siml functions, for example, have to be descriptors.)

A program is still compiled into an imperative style Python program, with only floating point numbers, strings, and booleans.

The compiler is still beta quality, it can quite easily be tricked into erroneous behavior.

New alpha 2 release available!

2nd release (0.4.0a2) of the new architecture. The language has the 'if' statement back! Still missing are boolean operators (and or not).

Error messages are still bad, and there is still no optimizer.

Unfortunately there is a mysterious bug in the parser which makes the parser crash when complex or long programs are parsed. One oft the examples had to be shortened because of this bug.

Alpha release 0.4.0a1

Written for Freeode by Eike on 2009-06-12

An alpha release of the new architecture is ready!

Get it at: https://developer.berlios.de/project/showfiles.php?group_id=5610

Currently the compiler does not have an if statement, but it will be implemented soon. Error messages, and the ability to find errors are quite poor. Only two example files have been converted to the new syntax:
models/biological/bioreactor.siml
models/biological/bioreactor_simple.siml
