Another question: In the code I saw. ReadOnlyVariableBinding. I removed that in Pharo relatively early as it was not used: half of the classes were stored that binding (old ones) all newer ones where just associations. The code to make a binding read only was never called. Is this now used in Squeak? Is it worth the complexity? Squeak doesn't use ReadOnlyVariableBinding anymore. The bindings of classes are instances of the ClassBinding class. Without using separate class it's a bit cumbersome (and less OO) to decide if an assignment to a global variable should be allowed or not. E.g.: Foo := 1. should work if Foo is a global, but not a behavior. It should raise an error if it's a behavior. I have mixed feelings about that. In most Smalltalks one can write something like the following and expect it to work. | original | original := SomeClass. [SomeClass := SomeReplacementClass. ... some code involving SomeClass (typically a passed in Block) ... ] ensure: [SomeClass := original] That is, the name of the thing is not the thing itself. Of course, as long as one could write /Smalltalk at: #SomeClass put: SomeReplacementClass/, it would still be possible to achieve the same effect. (And of course, Smalltalk could be any namespace.)

[Pharo-dev] Switching to Pharo from Visualworks
Hello PharoDev, I have a largish project (Siren) that I have developed in ST80/VisualWorks (since 1984) and ported to Squeak in the past. I'm allows looking for a cleaner free ST80 implementation to host the project. Looking at Pharo, it appears to me to be suffering the same bloat issues as Squeak. I have a few questions: Why don't you all use a 6-paned browser (called the package browser in Squeak) and control the introduction of top-level meta-categories? The top-level (packages or meta-catgories) should be a list of 20 or fewer topics such as Magnitudes, Collections, Graphics, Text, Compiler, Tools, etc. and each of these should have 20 or fewer categories within it. I ported the package browser to Squeak and reorganized their system once, but people continued to add top-level categories to make finding their code easier. I tried to add the facility to the Pharo browser a year or so ago, and gave up because I couldn't figure how out how to subclass and refine the existing browser framework (and the fact that it seems to be under construction). Why do you still use the (terrible, IMHO) Squeak graphics and UI packages (Morphic, Balloon, etc)? It appears that new mostly-redundant systems are still being added to replace these, right? Can't someone reimplement the VisualWorks Wrapper UI framework (or something like it) on top of OpenGL contexts as in VW? It's help up pretty well after over 25 years. (David Leibs and I toasted it just last December in Australia.) How does a newbie learn what all the new packages are for? Glamour, Ring, AsmJit, Zinc, etc. are neat names, but if they're not part of higher-level packages it makes navigating the system (and even figuring out what they're for) pretty difficult. Are there any benchmarks of the current VMs compared to VisualWorks? The last time I used Squeak (a few years ago) it was still pretty slow. I have a real-time event scheduler in Siren that I use to schedule MIDI, so I can run drum roll tests to see how the VM performs. How does Pharo handle user primitives or foreign function calls? Is anyone maintaining the old SWIG implementation of Smalltalk? I used it quite a bit to have Smalltalk code create and manage C++ signal processing graphs in the past. SWIG is still going strong, and it's embarrassing that there's no mention at all of Smalltalk on the SWIG pages. I'm not trying to start a fight, and I really did like the initial Pharo mission statement of making a tighter, cleaner open-source ST80 implementation. Is that dream still what motivates the community? If yes, where are the minimalists hiding?

Is that dream still what motivates the community? If yes, where are the minimalists hiding? There aren't that many high level categories. Any trip to Java? One can reduce the list with any regex in the box above the list and get that reduced list. e.g. ^Kernel There is a SWIG that supports Pharo. Check the Woden project as it used SWIG to wrap OpenGL/OpenCL. The SWIG thing is in the rmGithub repo of the Woden developer. Read Deep into Pharo for explanations on some packages. Also go to squarebaracketsassociates on github for books in progress etc. Id you want to create browsers maybe your best bet is to go the GToolkit route. Glamour is the framework supporting all of that. Nautilus can feel a bit unfinished but that's one get when challenging the status quo and learning how to go the the next level. Graphics are supported by Athens which wraps Cairo. Look in there, there is quite useful material. OSWindow and libSDL bindings open the door to better/faster interactions. I like Morphic and Balloon as they help me get how things are happening under the hood. FFI options experiences lots of attention at the moment. FFI as in original FFI works. Alien is there but kind of stale. NativeBoost works on x86 uFFI is a bew thing. One can also use the CCodeGenerator from inside the image. Need to load it first. BTW, I like your work and would love to see it working in Pharo.

There is no such tools in Pharo, but you can use the filter to see only the package you want. You may have a look to the AltBrowser of Thierry Goubier : http://thierrygoubier.github.io/AltBrowser/ There is a hierarchical view like the one you want.

I do this: - Shift+Enter - Spotter is opened without preview - Cmd+P - preview is opened - Esc - Shift+Enter - Spotter is opened with preview - Cmd+P - preview is closed - Shift+Enter - Spotter is opened without preview Does this not work for you in this way?

We think this boosts the usefulness of the Spotter interface significantly. spotter-method-preview.png Really cool. I updated my pharo4 to 474 and can see the preview. But once switched on it seems to stay that way. Cmd+P does not remove the preview. Closing and opening the spotter again shows the preview opened. Norbert For more details, please take a look at: http://www.humane-assessment.com/blog/boosting-gtspotter-with-preview This is available in the Moose image, and it will soon be integrated in the Pharo one.

Re: [Pharo-dev] Anonymous classes should be browseable
I will reply to this by private e-mail. There are many aspects of Nautilus that I do not like but there are even more aspect about the old browser and OB that I hate! And as you know doing is difficult. You know I wrote several OB browsers so I know OB had problems. OB was not *that* bad. The old browser was. But I just spent too much energy on OB. :) What do we do with class side? packages? Why do you expect that a tools supporting the Smalltalk metaclass model should suport Anonymous classes? Because tools should be flexible enough to support other similar artifacts (like anonymous classes) at least without too much modification. How we can evolve if tools are not adaptable? now classes belongs to a package so the class browser assume that your class must belong to a package. BTW I'm the guy in Squeak that fixed long long long time ago Behavior new new (So I know a bit on anonymous classes). When I used anonymous classes I did it to support instance based programming. So should I expect my hack to work with normal browser? When I think about halting SystemWindowdelete automatically I miss the instance-based behavior. I do not consider it a hack. Now Glamour could be a solution? It would support building tools for all the other experiments (MethodWrappers, Ghosts, Multi-Methods, Wide Classes, etc)? May be. :)
[Pharo-dev] '/is/this/possible?' asFileReference size
Hi, I just discovered that if you ask #size to a non-eistent file reference you obtain False. I submitted an issue @ https://pharo.fogbugz.com/f/cases/14862/is-this-possible-asFileReference-size Cheers, Roby
Re: [Pharo-dev] Who are the experts?
Sorry for the late reply, Stef. Cool that you cleaned AbstractTool and about the second part of my email.. I was indeed wrong!

Why there are different methods to remove a class, for example? e.g., NautilusRefactoring#removeClasses: vs. AbstractTool#removeClasses: I looked at it and clean it a bit. Now AbstractTool is common to all the tools. NautilusRefactoring introduces refactoring at the level of nautilus hence redefines the methods. - Why #removeClasses: is triggered before the actual removal (i.e., confirmation dialogue)? where? because this is not what I see.

[Pharo-dev] Empty Package Names
I noticed that in 4.0 one gets a (resume-able) exception when trying to define a class in category ''. Why? Is it true, as the error message states, that the Category should not be empty? One of our key principles inherited from Smalltalk is to treat the programmer like they know what they're doing. Although only a minor annoyance in this case, I often create classes in empty categories specifically because they are throwaways - like a temp directory, and was a bit confused by the debugger popping up, especially before I realized that the exception was resume-able... Also, that made me think about something else... What if the debugger somehow made it immediately obvious whether the exception was resume-able? That could be useful in cases like these to make the user's options clearer. - Cheers, Sean -- View this message in context: http://forum.world.st/Empty-Package-Names-tp4803642.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Which is not good, as it will be dirty. Maybe we could have a general place for all these? Marcus

Re: [Pharo-dev] How Stable is Pharo 4.0?
Well I would not just call it painless more like a very big improvement over Pharo 3. No strange bugs and abnormal behaviour so far , and I have been using it for more than a year.

Thanks I work now on a daily basis with it. The downside ist that some DNUs lead to infinite loops in somewhere around #stepToCallee. The upside is GT inspector/spotter. It really is a lot of fun to get used to it. Today I learned it is a good idea to close all GT windows before upgrading. :) My experience so far is that I can kill pharo 4.0 much easier than pharo 3.0 but the overall experience is good. hope that helps, Norbert
