RBEnvironments allClasses/Traits/Meta ...

Nicolai Hess
Hi,

some time ago Yuriy cleaned up the RBBrowserEnvironment methods for
allClassesAndTraits(Do), classesDo, ....

The fix was good and necessary (I think). But they had an impact
on some SmallLint-rules (they arent applied on the class side) and the behavior
for the different Environments changed (compared with Pharo3
(-> 14621 Some RBBrowserEnvironments don't work well with Metaclasses))

As some SmallLint-rules need to iterate over the metaclasses as well and
I don't want to revert Yuriys change, I 'll add another method that
collect classes and metaclasses.

So, I need some help, how to name this methods:

all classes (Object, Integer, ....) -> allClasses, ok
all classes and metaclasses (Object, Object class, Integer class ) -> ? allBehaviors?
all classes and traits -> allClassesAndTraits, ok
all classes and meta classes and traits and class traits -> ? no idea!
all metaclasses and class traits -> allMeta(ClassesAndTraits) ? I don't know if we need this

One problem with "allBehaviors" is, SystemNavigation uses allBehaviors to iterate
over classes, metaclasses, traits and class traits,
allthough a Trait is not a Behavior. (TClass isBehavior -> false)

feedback is welcome

I’m ready to help with this issue, but as far as I can tell, it’s not hard to implement the mentors. Here we should decide on the meaning of the phrases. What are "all behaviors” and so on. The reason of the refactoring that I’ve done was that there were two methods with similar names that were doing different things.

What if rules that need metaclasses ask for them explicitly to the class?

environment allClasses do: [ :theInstanceSide |
   self doSomethingWith: theInstanceSide.
   self doSomethingWith: theInstanceSide classSide. ]

Just putting another possibility on the table...

I would say, that besides #checkClass: and #checkMethod: rules should also have #checkMetaClass: this will allow rule developers to be more flexible, and will add a bit more certainty.

Because sometimes you need to check both, then you implement a method and call it from #checkClass: and #checkMetaClass:. Sometimes you only need to check one of them. And you will always know that metaclass will not sendup in your method.

And maybe we should exclude traits and provide a checkTrait method, because now there are some lint rules failing because there is code like
checkClasse: aClass
|meta|
meta := aClass class.
.... check on meta


and if this method is called for a trait like TBehavior, TBehavior class ->  Trait
meta is not the classTrait of TBehavior but the Metaclass of Trait.

Ok, I still struggle with the right naming convention.

For example, consider the method

#flushEvents

this method is send by
SmalltalkImage garbageCollect
SmalltalkImage shutDownImage:
WorldMorph installForUIProcessReinstall
and the *class side * method
Object class flushEvents.

What would you expect this method returns:
" the classes of the  environment fore references to #flush events"
(RBBrowserEnvironment new referencesTo:#flushEvents) classes

1. SmalltalkImage/WorldMorph/Object class
2. SmalltalkImage/WorldMorph/Object
3. SmalltalkImage/WorldMorph

1, because all three classes resp. the meta class "Object class" refer to this (this is how Pharo 3 behaves)
2, because all three classes have a method on the instance or class side refering to this (this is what I would expect)
3. because there are only two non-meta classes refering to this method (this is how Pharo4/5 behaves)

?

I don't know, but this is crucial for deciding the way on how to clean the current RBEnvironments implementation.

Re: RBEnvironments allClasses/Traits/Meta ...

stepharo
Since you probably want to query a method after on the class, I would return 1
#flushEvents

this method is send by
SmalltalkImage garbageCollect
SmalltalkImage shutDownImage:
WorldMorph installForUIProcessReinstall
and the *class side * method
Object class flushEvents.

What would you expect this method returns:
" the classes of the  environment fore references to #flush events"
(RBBrowserEnvironment new referencesTo:#flushEvents) classes

1. SmalltalkImage/WorldMorph/Object class
2. SmalltalkImage/WorldMorph/Object
3. SmalltalkImage/WorldMorph

Because if I want two this is easy
   
    query collect: #theNonMetaclass

1, because all three classes resp. the meta class "Object class" refer to this (this is how Pharo 3 behaves)
2, because all three classes have a method on the instance or class side refering to this (this is what I would expect)
3. because there are only two non-meta classes refering to this method (this is how Pharo4/5 behaves)
3 is a bug!
When we look for refs we should get them all.



?

I don't know, but this is crucial for deciding the way on how to clean the current RBEnvironments implementation.

oh yes!
Thanks for looking into it.

RBBrowserEnvironment default allClasses size. 5012
RBBrowserEnvironment default classes size.  5012

-> I "define" the Pharo 4.0 behavior as the correct one. RBEnvironment>>#classes should not contain meta classes.

Some other RBEnvironments and/or RBRules rely on the "classes = classes and metaclasses" (-> see issue
Some RBBrowserEnvironments don't work well with Metaclasses
Some rules aren't applied on the classside anymore
a RBEnvironment from #referencesTo: does not list meta classes

I will change them, and if appropiate, add a new
classesAndMetaclasses resp. classesAndMetaclassesDo:

I don't know about classesAndMetaclassesTraits. And I skip "behaviors" for now.
#allBehaviors is suspicious to me, I still don't
know what they are:

Smalltalk globals allBehaviors includes:TBehavior. -> true (1)
TBehavior isBehavior. -> false (!)
