Scout comes with powerful tools in the Scout perspective. You have a logical representation of your application in the “Scout Explorer” view and a “Scout Object Properties” view where you can set or change a property for the selected object. A modification in the property view updates the java code and a code modification is reflected in the property view. This allows the developers to work as they want.
The problem is that power users are not using this property view very often. The explanation is simple: using the view breaks the flow when you are typing code in the java code editor. You need to switch to the mouse, find your current object in the scout explorer and set the properties in the other view.
When you know the name of the getConfigured method you want to set, then you are quicker if you stay in the java editor. The problem is that what the JDT is offering by default is not really what you need in this case. Lets see how Snipmach can help.
With the JDT
If you are in a column’s inner-class you might want to define it as editable. You need to override the getConfiguredEditable() method and return true instead of the default false.
The JDT can help: enter “getCondiguredEdit” and press control space:
This works well, but the result is not as efficient as it could be:
My problems are:
* I really do not need the “(non-Javadoc) comment” block.
* The cursor is not at the correct position; It would be preferable to have the cursor in the line of the return statement.
* In this specific case I do not need to call the super implementation at all.
* And the TODO statement makes sense in a lot of cases, but not here.
Snipmatch can help too. I have defined snippets to handle those cases. They are shared in this git repository. In my column, press CTRL + Alt + Space + the search filter set to “edit”, I can find the snippet I am looking for:
Now when I press enter, there is a big difference with what the JDT override assist function provides:
The cursor is where it should be. In the Snippet’s definition, I have defined as first choice the value that will be most likely used at this point (in this case true because the default in AbstractColumn is false). The result is really straight forward.
Just to be clear, I am not complaining about the JDT doing a bad job. We are comparing a generic feature coming out of the box in the JDT and another approach where someone needs to configure the possible snippets. It is normal to have a better user experience with a specific tool because it is a specific use case.
What is missing in snipmatch?
The snippets do not have any metadata to define a context. The consequence is that the search engine is only based on the keyword entered by the user in the search box. It would be nice to be also able to influence the search result depending on the cursor position. I have commented Bug 435632. Let’s hope that the code recommenders team will propose something going in this direction to improve the user experience.
