I'll try to getting it working under GLASS but I don't have a lot of time. I got this response on the GS/SS Beta mailing list from James Foster: "Larry, Porting an application fromPharo to Version 3.0.1 should be similar to porting to 2.4.4.x. There are a number of new features (some, like FFI are necessary for you) and performance enhancements. On the other hand, people who have existing projects have not rushed to migrate from 2.x to 3.x so there is not as much production experience with Seaside on 3.x. I've been porting some of our tests to use FFI and have found a couple issues with the VM that should be fixed in 3.0.2 (schedule pending based on demand). I have also done a bit to improve the CHeader parsing. It is certainly our goal with FFI that it be fairly easy to use. In the last hour I've come up with the following in 3.1, and expect that it should be similar in 3.0.1. First, build a class that represents the library: | header class | header := CHeader path: '/usr/include/openssl/sha.h'. class := header wrapperForLibraryAt: '$GEMSTONE/lib/libcrypto.so'. class initializeFunctions. UserGlobals at: class name put: class. Next, use the library: | string result bytes | string := 'Now is the time for all good men to come to the aid of their party'. result := Crypto new SHA1_: string _: string size _: nil. bytes := result asArray collect: [:each | each codePoint]. result class -> bytes. String->anArray( 249, 92, 62, 72, 141, 165, 168, 163, 45, 23, 107, 2, 204, 233, 20, 250, 66, 180, 132, 37) I don't know anything about SSH-1, but this seems to match the info I found (using Google) at http://linux.die.net/man/3/sha.

Re: [Pharo-project] New IDE alternative (was Misc. newbie questions)

Hi Stefan, > Because I fear that you are talking about what I used to know as Borland Delphi.(http://www.blichmann.de/en/programming/delphi/themeddelphi/luna.png) > Not that it is bad, but like Visual Studio and Eclipse, the main concepts are IMO as dated as what you got in Pharo. Actually, it's now Embarcadero Delphi, but yes that's what I'm talking about. I'm not talking about the visual aspect of the environment. What I'm talking about is the dockable windows and the tight integration of the different IDE components. For example, you double click a button and your placed in a code stub for the click event in the editor. You don't have to go hunting for things. For example, one thing I don't like about VisualWorks is the gui framework. It's gets in the way with imposed MVC. If a developer wants to use MVC then they can code that way, but I don't think it is the IDE's or framework's job to force it. It just needs to be a simple event based model. Actually, when it comes to gui toolkits Nokia Qt is the best. MVC is an option, but not forced. You could use QtCreator as a substitute for Delphi above. The idea is still the same. I guess some examples of what I'm wishing for would be: 1. A code editor that will allow editing a complete class in one go (with code folding etc.) 2. The concept of projects and subprojects. All project classes are readily accessible without drilling and searching. 3. A code aware gui designer. 4. The ability to switch between gui design and code within a tabbed editor. 5. The ability to have all project classes open in editor tabs/panes at once. 6. A tree based system browser with separate tabs for system and project classes. ... > > If you are just looking for a UI designer, have you seen this? https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki… Yes. I have seen this. It would definitely be nice to integrate it with the ideas above. Thanks, Gerry

You have a point in that people new to Smalltalk might be used to something and not realise that they're used to pain and suffering that they needn't suffer. The reverse is also true: we too as a community have blind spots, and put up with pain and suffering because we've just gotten used to it. frank

Re: [Pharo-project] Problem with Arch Linux and Cog

by Alexander LazareviÄ

2012/1/11 Milan Mimica <milan.mimica(a)gmail.com> > > The proper fix to all of this problems would be to provide distribution specific packages. I know that's a lot more of work and many more people should be involved into this, but how hard can it be? Any piece of software aimed to linux has packages for most popular distributions, so it is doable. Sure! Please note that Ian Piumarta, the maintainer of the original (stack) VM for unix did provide packages for RedHat and Debian systems early on. There are still packages for the latest VM for RedHat/Suse? on [1]. I think Matej Kosik, JosÃ© Luis Redrejo and others took the labor of building a license clean squeak-vm packages, which got accepted by Debian [3] and Ubuntu [4]. I'm not sure about their current status and do not know about other distributions. I don't think that projects like the linux kernel, gnome or whatever all build packages for every linux distribution that's out there. It's true that there is a different demand after the linux kernel than after the squeak-vm. But we still have limited resources and can only hope that squeak/pharo/cuis keeps attracting people, so that they get included in some distributions. The cog VM might be the standard VM inside the pharo/cuis/squeak communities, but it's still experimental and only for x86. So there is the question how to integrate the cog vm/stack vm both into eg. the debian distribution that is also targeting amd64, mips, mipsel, powerpc, s390, s390x, sh4. You can't just provide a new squeak-vm package that contains the latest cog vm.
