Lack of examples and request for help in using PEG

[LazarenkoA]

Hi there,

I've been exploring the examples in your repository, and I find that there's a significant lack of sample input data for a better understanding and debugging. It's quite challenging to grasp, especially for someone who hasn't worked with PEG before.

I have a task at hand to write a parser for a specific domain-specific language (DSL). The ultimate goal is to generate an AST tree, and the language has a fairly simple syntax. For instance, here are some sample conditions:

If CurrentVars = Undefined Then	
    CurrentVars = New Structure;
EndIf;

And here are sample loops:

For Each Attrib In ActionItem.Attributes Do
    CurrentVars.Insert(Attrib.Name, Attrib.NodeValue);
EndDo;

Could you provide guidance on how to configure the parser? Even a basic setup to get me started would be immensely helpful. From there, I can take it forward on my own.

Thank you in advance for your assistance.
