Thanks a lot Bill. I found this posting from Ian sent on 1-Aug-2000.
BTW - I have quickly found it using DSDN nice thing. DSDN is nice
however newsgroup archive does not include mail attachments. It seems
like we are going to lose all this valuable software because of switching
to comp.lang.smalltalk.dolphin (old newsgroup will be killed some time from now
- according to Andy).
Of course Ian's trick works and is simple. However I am going to do something more
(so to say...) sophisticated namely:
1. capable of browsing over arbitrary set of classes
2. adding a class to this subset by simply dragging it from another CHB window
3. subset means method/protocols/categories filtering too
4. synchronization (adding and deleting class/method propagates to all
active browsers)
5. fast browsing (Ian's solution is simple but a little slow)
6. protocol browser compatible with the framework
I would like to have a browser which really allows to focus on solving
one problem. Let "layer" denote such browsable subset of classes/methods/protocols.
Then while working on a project, developer works on a couple of layers. These layers
(=the way things were logically partitioned to layers) are important element
of technical documentation of the project.
In some way this is simply extension to old idea of class categories.
BTW it is interesting that dolphin classes ARE categorized in old good Smalltlak-80
style ! For example try to evaluate this:
ClassCategory allInstances do: [:x |
Transcript cr; show: '----'; show: x name;cr.
Class allSubinstances do: [:c |
(c category = x) ifTrue: [Transcript show: ' ';show: c name;cr]]]
It is a pity that (so far) dolphin browsers are not showing class categories.
OK, context menu in the class pane in CHB contains "category" but I bet you 5 pounds
that hardly one knows that and no one uses).
Not being discouraged I am going to use this in my browser. The fact that given class
category spans a layer means that my browser will also be (functionally) extending
the classical CHB found in Smalltalk-80 (Squeak alse has such a browser for example).
I hope all said above will end with some usable and nice little goodie ;-)
