[lively-kernel] finding a class

[c***@afilha.com.ar]

Hi, I am familiar with Smalltalk and teaching myself the Lively Kernel.
While browsing the TodoList via object editor I sea fragment of code
like this

var item = this.get("TodoItemProto").copy();

How do I find the TodoItemProto class? Is there a way to select the
class name from a method and jump to the class browser open in that
target class?

Regards, Carlos

Thanks Lars, the programmatic method you explained is very useful.
However I was interested in a manual method to find a class. either in
the System Code Browser or thru the world menu

Hello Carlos,
in oder to get to the TodoItemProto class, just ask the morph for its
constructor. When printed, that gives you the class' name. If you want
to know where the class is from, ask the constructor for it's source
var klass = this.get("TodoItemProto").constructor
var source = this.get("TodoItemProto").constructor.sourceModule
Methods defined using the lively class scheme have an attribute
"declaredClass" which contains a string which should yield the class
object upon evaluation.

THe manual method for searching is to press CMD-Shift-F / Ctrl-Shift-F
inside a text (searchign for selection) or outside. A code search window
will pop up. The search will find what's loaded into the Lively runtime
(classes, modules, methods, objects). By pressing the "search on server"
checkbox you are switching to a completing string search that covers all
code that the server has access to.

Best,
Robert

The TodoItemProto in this example isn't a class. It's the name of a morph
somewhere in the world. Finding it's class won't be useful.

As Tim said, TodoItemProto is not a class but a (prototypical) object that is cloned (.copy()) everytime you create a new TodoItem using the + button.

How can you find it? Usually [morph].show() will highlight the morph in the work showing red corners. If you do it for this example (this.get('TodoItemProto').show() in the Object Editor), you will see that it must be hidden behind the Progress Bar somewhere.

Digging further into it by inspecting the morphs and submorphs of the Todo Item Tool, you will find the TodoItemProto as a submorph of the TodoList container (not the window though). It is not visible so it will not be affected by the horizontal layout and you cannot see it.

How can you find that out programmatically? From the Object Editor, print or inspect this.get('TodoItemProto').owner. :-)
