Parsing and code-generation for the Model Specification Language (MSL) compiler.

In this prototype we integrate AToM³ with the parser from prototype1.
The directory with the code: prototype1.tar.bz2.

Setup

Save the file to your AToM³ directory and unzip en untar it.
Type "make" in the directory. This generates the file msl.so.
Change your AToM³ options (Marcs tutorial).
Start AToM³.
Load the meta-model algebra_entities.py

Use

When the meta-model is loaded you should get this screen:

Press the "parse expression"-button, the follwing window will popup:

In this window you have the choice between parsing a string or a file containing expressions. You can also choose to display the trees vertical or horizontal.

String

Enter the expression and press "OK".

File

Select the file and press "Open".

Saving parsed expressions

Like every model: File->Save model.

Remarks

When you parse more then one expression or a file containing more then one expression the trees are displayed in a way that they do not overlap. This property is part of the parser (C-code) and not of AToM³ (Python-code). This is not realy OO, so a fix is needed.
