[TCS] playing with km3 metamodel and syntax [message #380601]

Using the TCS wizard, I started to build very simple projects. My setup
seems ok since I successfully injected different textual files to models
(with different metamodels). Eventually I tried to import km3 and tcs
files from the KM3 2007 project available from the TCS ZOO
( http://dev.eclipse.org/viewcvs/indextech.cgi/org.eclipse.gmt /AM3/dsls/KM3-2007/)
in a new TCS language project.
But then, whenever I write a very simple file like try.km3 below

try.km3:
package pack{
class cl {
attribute att : Integer;
}
}

the parser produce the following error in the "Problems" tab:
Classifier with name = Integer was not found for type of KM3!Attribute

It seems that primitive types aren't recognized?
I can still inject try.km3 to try.km3.xmi and get the corresponding
model (see below),

try.km3.xmi:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Metamodel xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="KM3">
<contents name="pack">
<contents xsi:type="Class" name="cl">
<structuralFeatures xsi:type="Attribute" name="att" lower="1"
upper="1"/>
</contents>
</contents>
</Metamodel>

but the attribute has no type.

I think I don't precisely get the way PrimitiveTypes are handled in TCS,
and help would be appreciated.

Regards.
Antoine

Hi Antoine,

You have to declare PrimitiveTypes in each .km3 file (as you would see
in any metamodel in the language Zoo). Here you would have:

package pack{
class cl {
attribute att : Integer;
}
datatype Integer;
}

or define this datatype in another package (but in the same .km3 file).
Let's named it PrimitiveTypes for instance:

package PrimitiveTypes {
datatype Integer;
}

Best regards (and Merry Christmas),
Mikael

Thanks a lot Mikaël, I forgot about that!
