[ATL] Run an ATL query [message #101815]

Hello,

My question is about the current available way to run an ATL query:

Is it simply with a Run configuration (if so, I tried it and it does not
generate any output text file, not even errors) or with an AM3 ANT script
just like this example
http://wiki.eclipse.org/index.php/AM3_Ant_Tasks#Examples_2 ?

PS: I am using eclipse 3.4.1 and ATL 2.0.2.

Thank you in advance.

Regards,

Hayfa.

Hi,

yes, you can launch an ATL query by using a Run configuration or an AM3
task. In both case you should:
1. print the result in the console
or
2. save the result into a file

You can print the query result using the keyword debug, like that:

query test = 1.debug('result');

You can save the result into a file as follows:

** Run configuration
query test = 1.writeTo('result.txt');

** AM3 task

<am3.query body="1" property="result">
<inModel />
...
</am3.query>

<echo message="${result}" file="result.txt"/>

Best regards,

Hi Kelly,

Thank you for your answer.

Actually, I have a problem with running an ATL query using a Run
configuration. It does not generate anything, not even in the console.
Normally , I can execute an m2m atl transformation without problem.

In fact, I am trying to execute an already existing example
(XML2ExcelText.atl) to generate an xml file.

PS: I am using eclipse 3.4.1 and ATL 2.0.2

Thank you.

Best regards,

Hayfa.
