Intentions Aspect¶ ⧉

Intentions provide fast access to the most used operations with syntactical constructions of a language.

MPS documentation

How can you go to the declaration of an intention when you open the intention menu?

Select the intention and click the arrow/press the right arrow key → Go to intention declaration.

How do you execute an action as an intention?

Add the action to the action group ActionsAsIntentions ⧉.

How can you group intentions and give them names?

Use com.mbeddr.mpsutil.intentions from MPS Extensions ⧉. Alternatively, you can split the description into multiple literals. The first literal will then be used to group intentions.

An Intention isn't visible, although it should be. What can you do?

Intention X should be visible on Concept Y. However, when I select an instance of Y, it is not listed in the intention menu. What can I do?

Make sure the language that declares the intention is in the Used Languages section of the model:

- Check if the intention applies to the concept you want it to apply to. (Maybe *visible on child nodes* is not set).
- Check if the *isApplicable* condition evaluated to true (try to avoid adding `System.err.our` prints to the model).
