How can I use haetae for static analysis of ETL ?
Can it fully detect errors for both declarative and imperative part of ETL?

Hi, Yes, Haetae is compatible with ETL, it is able to detect errors for both declarative and imperative parts of ETL. However, I would recommend to be cautious about the use of Any type - for best results, it is recommended to assign a variable (of any type) with the values that conform to the same type throughout the entire program.

If any problems please let me know.

Cheers,
Will

Thank you for your reply. In eclipse I went to install new software and enter the update site url. I went to Epsilon Haetae Preference and then Import all of Haetae files (that are in github) to eclipse. I create my project when I right click on my etl file, I have 3 sub menu in Epsilon Haetae. On which one of these should I click for detecting errors?
when I want to use source metamodel named Tree.ecore. How can I declare it in etl file?

To use Haetae, you need to go to the Preference settings in Eclipse, under Epsilon, tick "enable static analysis (experimental)". At the same time, under Epsilon Haetae, tick "Enable Epsilon Haetae (experimental)".

Haetae will take effect when these settings are applied.

You should register your metamodel before you declare it in your program. To do so, right click on Tree.ecore and select "register EPackages" from the menu.

You should declare your metamodel using the NSURI of Tree.ecore, if you are not sure what it is, In Eclipse, click Window -> Show View -> Other and search for "EPackage Registry", the registered Tree.ecore should be in the registry. What you need to enter is the nsuri. For example:

model Tree driver EMF {nsuri="http://www.eclipse.org/emf/2002/Tree"};

I hope this helps.

I did this settings and declared meta models but It couldn't take effect. Is there any plugins that must installed to Haetae take effect? (I only installed eclipse mars2 containing epsilon 1.3)

Hi, I have recently picked up with migrating Haetae to the new repository. And I noticed that the previous build had som problems for ETL and EVL supports. This problem has now been fixed, so please checkout the latest version and try again.

Cheers,
Will

Can I see .model file generated with Haetae in the form of class diagram?

Hi, to see .model in the form of a diagram you would probably need to generate an editor for ETL, which can be achieved in EMF. Alternatively you can use EuGENia [1].

Hi there,

How can I send a part of ETL or EOL program as string to Haetae and get its equivalent model programmatically?

Best Regards,
Banafsheh

+ I have also asked this question in github

Hello,

In Haetae, there are a number of creators which are responsible for generating models based on the AST. Please refer to [1].

So for a given segment of code what you need to do is to:

1) get the ast of it
2) feed the ast to one of the creators, not that wrong type of AST will yeild an error for you
3) get the in memory EOLelement and do things with it.

Hope this helps.

Cheers!
Ran

Thanks. I think the reference [1] has been missed.
