Grammer and types

[Ralf]

while trying to create a groovy MDG, I created a grammer which is able to parse my code.
The debugger shows me the correct type of my attributes in the AST viewer, however, when I import source, the model only shows the name, not the type of the attribute.

Any idea what could be wrong or how I could further debug this?

How is the grammar returning the type information? It seems likely that you're not returning it in the way EA is expecting to find it.

I used the SSL demo grammar as a starting point:

Code: [Select]

<attributeDeclaration>      ::= node("FIELD", <attributeVisibility> node("TYPE", <attributeType>) node("DECLARATOR", <attributeName>) [<attributeDefault>] [";"]);

<attributeVisibility>      ::= attribute("SCOPE", "public") |
                        attribute("SCOPE", "protected") |
                        attribute("SCOPE", "private") |
                        attributeEx("SCOPE", "public");

<attributeType>            ::= attribute("TYPE", <typeName>);

The AST result says something like

Field (Scope = private)
   Type = BigInteger

so, it seems to be right

OK. found the problem. The following page explains what the AST has to produce:

with this, I was able to figure out my problem...
