Hi everybody,
can anyone help me please how can i verify with ATL that for example a string "'task1_ready" contains a string "_ready".
In fact, i have many strings, for example, task1_ready, task1_working, task1_finish, and i need to get only the strings that contains "_ready".

Thanks in advance.
Regards

Regular ATL only supports the OCL 2.0 string operations (https://wiki.eclipse.org/ATL/User_Guide_-_The_ATL_Language#String_data_type_operations). EMFTVM allows you to use Java String methods on top of that, such as "contains".

Cheers,
Dennis

Hi Dennis,
Thank you for replying.
i installed EMFTV to try the java String method 'contains', but i don't find the way to use it in the tutorial available on internet. so, as i'm a starter with EMFTV, Can you please give me an idea how to call contains in an ATL code using EMFTV?
Can you please provide me with tutorials to start with EMFTV because i don't manage to find it on internet.
Thank you in advance

There's only the EMFTVM wiki page, which describes what is different from regular ATL. Once you've got your transformation running in EMFTVM, you can use "contains" as follows:
rule Test {
  from s : MM!S (s.taskName.contains('_ready'))
  ...
}


Cheers,
Dennis
