[Pharo-dev] editing in Spotter code pane
I've just started trying to make more use of the code pane in Spotter. It seemed ideal for the case when I want to add self haltOnce to a dozen methods. However when I hit enter to get a new line, Spotter closes. Additionally the Browser that opens doesn't contain the change I made in Spotter - they've been thrown away. I propose that when the cursor is inside the code pane, it doesn't close Spotter. Even at this late stage, could this be done for Pharo 4? Only because I am guessing this since Spotter is a core tool, this might end up a common complaint as people adapt their workflow to use Spotter more. Would it be safer at this late stage prior to Release that this be done as a Slice, to limit other changes that might come through the Spotter Configuration? cheers -ben

About your NativeBoost bug on openSolaris, need more information: - Can you confirm that you use an intel processor on your openSolaris machine ?

Yes, my Sun Ultra 24 is an Intel based Workstation (Q9300). - Do you build the Cog VM or Stack VM ? I mean PharoVMBuild or PharoSVMBuild ? I think the PharoSVMBuild does not include NativeBoost by default, that may be your problem. There's a fix somewhere... PharoVM from branch 'master' of https://github.com/pharo-project/pharo-vm; (thus Cog VM). I would like to fold back any changes into the svn master repository for Cog. What are the diffs? (If you have time to send me the diffs that would save me a lot of time). I don’t know whether there is much to harvest from what I did. As far as I remember most of my work was hacking the generator image created by the pharo vm scripts (for my Mac) in order to make the resulting C code to compile under openindiana. The basis for Solaris was already there (and as far as I can see it is also in the Squeak VM sources). I only tweaked some definitions and includes. I will look at my notes tomorrow and will post if I will find something relevant. I am curios about the future of the PharoVM. The main development of the VM seem to happen in the SqueakVM (by you). Getting the Spur changes into the PharoVM seem to be a lot of work. Note that this will happen (or is already happening). Esteban is working on building the Spur version of Pharo, so he is doing this work. But actually it *isn't* that much work. There is basically a trio of new memory management files for each platform, e.g. platforms/unix/vm/sqUnixSpurMemory.c, and a new source tree for the spur vm, spursrc/vm. The system is already set up to build multiple VMs (at least the svn tree is). Yes, this is already done. We are building spur VMs and images since awhile now. You can find all the related jobs here: https://ci.inria.fr/pharo/view/4.0-VM-Spur/ If I follow this link and what is being used there brings me to the ordinary PharoVm project on github: https://github.com/pharo-project/pharo-vm There are three branches: master, develop and spur64. Which one is being used to build PharoVM-spur32? And as Eliot says… is not *much* work… except when it is :) In fact, we were planning to release Pharo 4 (next week) with a Spur VM, but we didn’t finish all the small things around. So we will release next July (or around) a Pharo 4S (S, for Spur) with “official” spur support. We do not want to stay to much time in older versions. Also, our development process is different This explanation irritates me: Pharo 4 will be released soon with a Spur VM? And then around summer Pharo 4S? Isn't it a contradiction? than squeak, AFAIK… we drop backward compatibility in a regular basis. Which basically means we will move to spur and we will drop support for older versions. That's OK, but I am still, hmm say confused, because Eliot is changing A LOT (just look at what has been released during the last days), but PharoVM hasn't been changed for some days (I am following the master branch closely). So there is a rapid development in the Cog branch of the SqueakVM. The changes in the PharoVM are much slower (at least as I recognise it). I have more questions but I am reluctant to disturb you further as you must be quite busy atm. Best regards Andreas Wouldn’t it be better to move back the changes of the PharoVM into the SqueakVM and have a united development? Well, I don't think the Pharo community will be willing to move to svn.

Re: [Pharo-dev] FileUrl: Removal Rationale
Am 02.04.2015 um 23:55 schrieb Sean P. DeNigris s...@clipperadams.com: Sven Van Caekenberghe-2 wrote Having subclasses for each scheme is hard to maintain (there are hundreds of schemes)... It also makes little sense implementation wise. I’m not understanding. For one thing, in Core, we’re not interested in all of the hundreds of schemes but just the few most common (http, file) - although users interested in the specifics of other schemes could easily add those subclasses in their apps. Since subclassing is just a way to share code, wouldn’t a ZnFileUrl merely consist of exactly the methods we’re talking about - but more simply implemented? For one thing, it seems it would make extension easier. If I wanted to handle FileUrls and HttpUrls polymorphically with separate classes, no problem - implement two methods. But as it is now, IIUC I have to either implement two operation classes or have a method with a budding switch statement. Also, IMHO implementing a custom multiple dispatch seems exotic enough (i.e. takes extra effort to understand) to require a large benefit to justify. I think the problem is that URI structure/format and interpretation are mixed together generating that problem. Sven is right about not having additional classes for URIs. An URI is an URI regardless how it looks like foo://example.com:8042/over/there?name=ferret#nose \_/ \__/\_/ \_/ \__/ | |||| scheme authority pathquery fragment | _|__ / \ /\ urn:example:animal:ferret:nose The authority is optional, so URI wise there is no difference between a file URI and another one. The difference is in the interpretation of them. The interpreting part (the handler) is selected by the scheme. Having scheme as a registry would enable one to register his own handler for dealing with certain schemes. The downside is that dealing with URIs would be harder because you would need to use an extra selector between all calls that does the dispatch over the handler. A anZnUrl handler asFileReference This way there would be a FileHandler that implements #asFileReference. Other handlers might give a DNU. I understand the wish to keep the usage of ZnUrl simple not having to use extra selectors. But that wish turns out to be the problem IMHO and subclassing ZnUrl is not a cure for it just a way to make it worse. my 2 cents, Norbert

Spotter is primarily a search tool that has no modes. Editing in place is certainly an important use case, but we should not treat it lightly. For example, Enter is the keybinding for triggering the default action on the selected item. Allowing the editor to take precedence in handling it will introduce a mode and this will change the core of Spotter. And there is something else. Right now, the editor shows you the whole method including the signature because that is the default. What happens when I change the name of the method in the preview? This would require updating the search list, which is not a use case Spotter is made for at this point. All in all, I would not add this support now, because it requires more thinking. Would it be safer at this late stage prior to Release that this be done as a Slice, to limit other changes that might come through the Spotter Configuration? There will be another integration of GT before the release. Cheers, Doru cheers -ben -- www.tudorgirba.com Every thing has its own flow

Isn't it a contradiction? no, Pharo 4 will be released *without* spur, then we will release a 4S *with* spur. than squeak, AFAIK… we drop backward compatibility in a regular basis. Which basically means we will move to spur and we will drop support for older versions. That's OK, but I am still, hmm say confused, because Eliot is changing A LOT (just look at what has been released during the last days), but PharoVM hasn't been changed for some days (I am following the master branch closely). So there is a rapid development in the

[Pharo-dev] About PharoShortcuts
15288 https://pharo.fogbugz.com/default.asp?15288 Shortcuts in text editor are hardcoded I think it is a good idea to commonly name those short cuts. But this does not help to make the shortcut handling really configurable. For example, how would we change the shortcut for toggle comment ? - we need a setting that lists all PharoShortcuts, - change the keycombination in the setting - toggleCommentOnSelectionOrLine now would return the new shortcut But how do we populate the change to all users of this shortcut? We would need to rebuild all keymaps. (And if we want to save and load this shortcuts settings (load settings at startup), we need to rebuild all keymappings on every image startup). Instead, we could define commonly named Actions. A texteditor can register this action in its keymap and the action has a unique configurable KMKeyCombination what do you think? cheers nicolai

[Pharo-dev] Pharo 4 Beta, first impressions

Even worse, the Integer class' implementation of #atRandom references the Collection class to use that random instance! In other words, Integer#atRandom -- Collection#randomForPicking -- Random ! I've always been a fan of the mind your own business approach. Wouldn't it make a lot more sense to have the Random class provide a default instance (a singleton) whenever other classes need such an object instead of crippling the code with class variables and singleton instance all over the place? 3) I'm having a few Could not find disk drive errors on Windows XP ( never had that error with Pharo 3 and I've been using it every day since it came out).

Re: [Pharo-dev] Pharo 4 Beta, first impressions
The point is, every piece of code needs to be written and maintained which takes time and energy from other activities. However I imagine that taking the current Pharo theme and just moving the buttons around wouldn't be a complex task (or perhaps even making it customizable option). Personally since my OS doesn't use these buttons at all I don't really care at which side they are.

It’s there because I ported the code from JavaScript. The important part is that Java has signed 32bit integers. So, it works as expected out of the box. The SOM version shows the explicit operations you need if you don’t have any knowledge about the underlying integer representation. In most SOM implementations, integers happen to be represented as 64bit values, that overflow into some form of big/large integer representations. The sign-related operations are necessary to get the correct shift and overflow semantics. I guess I could implement it easily on a 64-bit Spur image, but I haven’t looked into that yet.

I think some people used it and it was at least partially working. That’s my impression. The VMMaker contains some FreeBSD classes but I have the impression that they are not complete (and probably outdated). About your NativeBoost bug on openSolaris, need more information: - Can you confirm that you use an intel processor on your openSolaris machine ? I assume that yes but I ask because solaris were typically running on other processors. NativeBoost, as of today, works only with intel processor. Yes, my Sun Ultra 24 is an Intel based Workstation (Q9300). - Do you build the Cog VM or Stack VM ? I mean PharoVMBuild or PharoSVMBuild ? I think the PharoSVMBuild does not include NativeBoost by default, that may be your problem. There's a fix somewhere... PharoVM from branch 'master' of https://github.com/pharo-project/pharo-vm; (thus Cog VM). I would like to fold back any changes into the svn master repository for Cog. What are the diffs? (If you have time to send me the diffs that would save me a lot of time). I don’t know whether there is much to harvest from what I did. As far as I remember most of my work was hacking the generator image created by the pharo vm scripts (for my Mac) in order to make the resulting C code to compile under openindiana. The basis for Solaris was already there (and as far as I can see it is also in the Squeak VM sources). I only tweaked some definitions and includes. I will look at my notes tomorrow and will post if I will find something relevant. I am curios about the future of the PharoVM. The main development of the VM seem to happen in the SqueakVM (by you). Getting the Spur changes into the PharoVM seem to be a lot of work. Note that this will happen (or is already happening). Esteban is working on building the Spur version of Pharo, so he is doing this work. But actually it *isn't* that much work. There is basically a trio of new memory management files for each platform, e.g. platforms/unix/vm/sqUnixSpurMemory.c, and a new source tree for the spur vm, spursrc/vm. The system is already set up to build multiple VMs (at least the svn tree is). Yes, this is already done. We are building spur VMs and images since awhile now. You can find all the related jobs here: https://ci.inria.fr/pharo/view/4.0-VM-Spur/ If I follow this link and what is being used there brings me to the ordinary PharoVm project on github: https://github.com/pharo-project/pharo-vm There are three branches: master, develop and spur64. Which one is being used to build PharoVM-spur32? yes, I still didn’t merged with master. master still builds a regular cog vm. I’m working on spur64 branch now, here: https://github.com/estebanlm/pharo-vm/tree/spur64 the spur jobs are built against my repository for the moment. I see, that wasn't obvious. And as Eliot says… is not *much* work… except when it is :) In fact, we were planning to release Pharo 4 (next week) with a Spur VM, but we didn’t finish all the small things around. So we will release next July (or around) a Pharo 4S (S, for Spur) with “official” spur support. We do not want to stay to much time in older versions. Also, our development process is different This explanation irritates me: Pharo 4 will be released soon with a Spur VM? And then around summer Pharo 4S? Isn't it a contradiction? no, Pharo 4 will be released *without* spur, then we will release a 4S *with* spur. Ok, that makes sense. than squeak, AFAIK… we drop backward compatibility in a regular basis. Which basically means we will move to spur and we will drop support for older versions.

Hi Stefan,
if seed is Andes with 16r when it is initialized then the Java code

Fix stuff until it loads fine in 4.0.Try and use the library in a simple demo project. Best yet, write a blog post about it.

Which JSON library (of the several available) is faster at parsing large json objects in Pharo 4? That sort of thing. * Write blog posts in general! Write tutorials and walkthroughs on how to use some of the new 4.0 features. Do programming puzzles / interview questions and post about em. Share tips on how you theme and customize your Pharo images, which tools you use most, and so on. * As mentioned before, at least browse the open 4.0 issues on the pharo FogBugz.

Re: [Pharo-dev] Can we have basicRaw in GTInspector?
The Playground has inspect on Cmd+Shift+i as requested by you. Ok good to know because this is important. What aboout an help? There is a problem with the update as it does not scale in the current form. Please see the reply of Andrei. We will likely remove that feature for the release. Just to clarify: When did we ever say that someone is stupid? Esteban told me that it was not freezing when we had to trash the image. Just that the machine was slow. To me this is a non answer. If we could get a real raw = basic inspect tabe then we can use GT and work. To me the raw tab with an explorer inside is counterproductive: we can get lost, it is slow, it does not work well with navigation of GT.

[Pharo-dev] [Pharo-users] Pharo sprint on Friday, 3rd April
On Fri, Apr 3, 2015 at 12:41 PM, Martin Bähr mba...@email.archlab.tuwien.ac.at wrote: nice ideas. though beginners may not have any favourite projects. are there any stats on which projects are popular so those can be chosen for testing? You're right. I think by 'favorite', I meant more like 'areas you care about in general, even outside of Pharo'. For example, say you're interested in data processing in general. You can ask, How would I go about downloading a comma-separated (CSV) file, read it into Pharo, and display a graph? This involves learning how to do File I/O, checking to see if there's a CSV library compatible with Pharo, and checking to see what sort of graphing libraries exist (I believe one was mentioned recently on the mailing list, Roassal or something). In similar vein, you can check out XML parsers, JSON parsers, etc, etc. Or you can ask How do I connect to a relational database? I've heard Glorp mentioned, and OpenDBX, etc, so which of these would actually work in Pharo 4?. Or, For example, maybe you care about social media APIs. You can then think, Hey I wonder if there are any Twitter or Facebook client libraries for Pharo. Maybe there's an Open Social API ( http://en.wikipedia.org/wiki/OpenSocial ) library that I can check out. That sort of thing. * Write blog posts in general! Write tutorials and walkthroughs on how to use some of the new 4.0 features. same problem here, being new to pharo, i would not even know what the new features are. this should be documented in release-notes probably. Of course, understood. Then write posts about new user impressions of Pharo 4 (keeping in mind the usual this is open source software / the devs are busy so don't be too harsh on them sort of stuff). Or short tutorials on the various small things that you've figured out to do. (Like a cron job that fires up your Pharo image on the command line).

Re: [Pharo-dev] About PharoShortcuts
Hi nicolai I'm not yet fully clear about the way we should handle keybinding. They look to me a bit like settings in the sense that a widget should be able to define its own but that the system could also push into it some predefined one. We should probably have a way to have local redefinition of binding. While we were brainstorming with Guille about we were thikning about having a command hierarchy as it was done in OB long time ago.

But this does not help to make the shortcut handling really configurable. For example, how would we change the shortcut for toggle comment ? - we need a setting that lists all PharoShortcuts, - change the keycombination in the setting - toggleCommentOnSelectionOrLine now would return the new shortcut But how do we populate the change to all users of this shortcut? We would need to rebuild all keymaps. (And if we want to save and load this shortcuts settings (load settings at startup), we need to rebuild all keymappings on every image startup). Instead, we could define commonly named Actions. A texteditor can register this action in its keymap and the action has a unique configurable KMKeyCombination May be :) I'm dead now. what do you think? cheers nicolai

[Pharo-dev] Ways to do 32-bit arithmetics?
Hi:
I am porting some benchmarks to Pharo, which rely on a deterministic random
number generator that uses 32 bit values.
In order to have properly comparable results across platforms, it needs to
generated the same sequence of numbers.
So, I am looking for efficient ways to implement it, any ideas?
I am a little at a loss, with SmallInts and Long Ints, how to get the proper
32-bit values, and how to apply the correct shifts, especially the right shift
can be problematic.
Code examples below.
Thanks
Stefan
In Java it looks like this:
private static int seed;
// Robert Jenkins' 32 bit integer hash function.
public static int random() {
seed = ((seed + 0x7ed55d16) + (seed 12)) 0x;
seed = ((seed ^ 0xc761c23c) ^ (seed 19)) 0x;
seed = ((seed + 0x165667b1) + (seed5)) 0x;
seed = ((seed + 0xd3a2646c) ^ (seed9)) 0x;
seed = ((seed + 0xfd7046c5) + (seed3)) 0x;
seed = ((seed ^ 0xb55a4f09) ^ (seed 16)) 0x;
return seed;

[Pharo-dev] VM and .sources in separate dirs question
While editing an Updated Pharo by Example chapter, I came across this: The '.sources' file and the VM can be read-only, and can be shared between different users. All of these files can be placed in the same directory, but it is also possible to put the Virtual Machine and sources file in separate directory where everyone has access to them. Is this true, that you can keep the VM and .sources in different directories? How do you tell the VM where to locate the sources? I assume it's some sort of commandline parameter?

Re: [Pharo-dev] Pharo 4 Beta, first impressions
If you want to argue about usage, this is probably more appropriate http://strawpoll.me/4001583/r (though Linux numbers are in reallity somewhat lower due to desktop+server) The bottom line is: nobody (from ~third of Pharo users) really cared until now so the options I see: 1. open an issue in Pharo issue tracker 2. a) write it yourself, or 2. b) ask someone who is interested in themes to write it If nothing fundamental changed in theming in Pharo 4, than moving the buttons around should take an evening with bottle of beer at most. If you want it in the default theme but customizable, that may take more, but it would be interesting. If you want the whole Windows theme than that may be a bit more.

Re: [Pharo-dev] Pharo 4 Beta, first impressions
lot of time ago we decided *not* to pretend imitate any OS LF, because is first a lot of work, and second a lose of time: they do not fit, and if you want to make them fit for real you need to spend *really* much time there (and you probably will fail anyway). Themes remained there without being maintained and they started to break. As no one uses it, no one noticed :) So we started to remove them. Now… I would like to not just remove anything, but to move them to a graveyard, where it can be revived by any necromancer who wants to give them a try. We need to improve there. w2k theme was… old. Didn’t fit with any current LF, not windows either. So, if you used the w2k theme just because of the icons (and also… I have to say it: windows and mac *is not* the same: windows is plenty of home-made LF that does not respect any design rule… mac is not like that). But well, coming back: if you want that old theme just for the icons, I just recommend you to take current theme and modify it to have the icons where you want (should not be so difficult). In the long term, it will be a lot more maintainable :) cheers, Esteban On 03 Apr 2015, at 16:07, Sven Van Caekenberghe s...@stfx.eu wrote: On 03 Apr 2015, at 15:57, Benoit St-Jean via Pharo-dev pharo-dev@lists.pharo.org wrote: Date: 3 Apr 2015 15:53:56 CEST From: Benoit St-Jean bstj...@yahoo.com Reply-To: Benoit St-Jean bstj...@yahoo.com To: Pharo Development List pharo-dev@lists.pharo.org Subject: Re: [Pharo-dev] Pharo 4 Beta, first impressions Kilon, I can perfectly understand that not everything has to be in the image and that, ultimately, someone has to maintain that code.

Hilaire [1] You can even still see in operation kind of DOS like operated application, mainly because it is handy for users. I guess Windows theme can serve the same purpose, may be this is what Benoit is explaining about. -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu
Re: [Pharo-dev] Pharo 4 Beta, first impressions
It's not as if someone would ask for an OS/2 or a Motif UI theme! There are *LOTS* of people on Windows still ! That is irrelevant really . Thats not how open source works. In open source something maintained or goes in or stays in because someone bothers to code for it. You may get 1 billion users to complain about this and still it wont change a thing. You still need a developer to do the work. Most open source devs like to work on things that they really care about. And is not as if things are better for MacOS user, the watery theme looks very dated , ugly and it is not even compatible with the new dark theme. So in the end it makes sense to use one of the recent themes, either white or dark. Also you are the first to complain about this.If you want to get this fixed the easiest way is to fix it yourself as third party library and add it to the configuration browser for others to use. If you expect for someone else to fix it, you may have to wait for decades and no it wont matter if you get a billion users to agree with you and sign a petition. How many people you think asked for a blue theme in this mailing list ? none . Pharo now has a blue theme because of me, and has no windows theme with so many windows users. How many people use the blue them ? most likely only me. Thats how open source works I am afraid, dont blame Pharo, blame life and the reality we live in :)

Re: [Pharo-dev] Pharo 4 Beta, first impressions
The point is, every piece of code needs to be written and maintained which takes time and energy from other activities. I completely agree with you. I have zero issues of main pharo developers kicking out libraries that are not so much used by pharo users. Those libraries are perfectly capable of existing as third party. I also love the plan to make pharo modular, remove libraries from inside and make it easy to install. This way each one of us can easily make an image tailor made for his/her needs. Each pharo user is an individual with individual needs. Installing libraries is dead easy with the Configuration Browser , including their dependencies , just one click away. Of course that leaves whos going to maintain that stuff. I agree with Marcus here, you want it in pharo , code it.The theme support in Pharo is very powerful , I know because I created my own custom blue theme and a tool to allow easy customization of theme colors with zero coding (Nireas). I expected that by now Nireas would be replaced by another way more powerful theme manager but it has not. Why ? Not because my theme manager is very good, but because the community is just too small. I love using my blue theme and fits perfect to my taste and needs ;) In the end no code can be more personal than the code you create. There is no need for everything to exist inside the image , great things can exist outside too. All it needs people who really care about pharo by coding for it.

I've always been a fan of the mind your own business approach. Wouldn't it make a lot more sense to have the Random class provide a default instance (a singleton) whenever other classes need such an object instead of crippling the code with class variables and singleton instance all over the place? This always annoyed me big time. Not just for what you said, but also because the access protection should not be there at all.

I think some people used it and it was at least partially working. That’s my impression. The VMMaker contains some FreeBSD classes but I have the impression that they are not complete (and probably outdated). About your NativeBoost bug on openSolaris, need more information: - Can you confirm that you use an intel processor on your openSolaris machine ? I assume that yes but I ask because solaris were typically running on other processors. NativeBoost, as of today, works only with intel processor. Yes, my Sun Ultra 24 is an Intel based Workstation (Q9300). - Do you build the Cog VM or Stack VM ? I mean PharoVMBuild or PharoSVMBuild ? I think the PharoSVMBuild does not include NativeBoost by default, that may be your problem. There's a fix somewhere... PharoVM from branch 'master' of https://github.com/pharo-project/pharo-vm https://github.com/pharo-project/pharo-vm (thus Cog VM). I would like to fold back any changes into the svn master repository for Cog. What are the diffs? (If you have time to send me the diffs that would save me a lot of time). I don’t know whether there is much to harvest from what I did. As far as I remember most of my work was hacking the generator image created by the pharo vm scripts (for my Mac) in order to make the resulting C code to compile under openindiana. The basis for Solaris was already there (and as far as I can see it is also in the Squeak VM sources). I only tweaked some definitions and includes. I will look at my notes tomorrow and will post if I will find something relevant. I am curios about the future of the PharoVM. The main development of the VM seem to happen in the SqueakVM (by you). Getting the Spur changes into the PharoVM seem to be a lot of work. Note that this will happen (or is already happening). Esteban is working on building the Spur version of Pharo, so he is doing this work. But actually it *isn't* that much work. There is basically a trio of new memory management files for each platform, e.g. platforms/unix/vm/sqUnixSpurMemory.c, and a new source tree for the spur vm, spursrc/vm. The system is already set up to build multiple VMs (at least the svn tree is). Yes, this is already done. We are building spur VMs and images since awhile now. You can find all the related jobs here: https://ci.inria.fr/pharo/view/4.0-VM-Spur/ https://ci.inria.fr/pharo/view/4.0-VM-Spur/If I follow this link and what is being used there brings me to the ordinary PharoVm project on github: https://github.com/pharo-project/pharo-vm https://github.com/pharo-project/pharo-vm There are three branches: master, develop and spur64. Which one is being used to build PharoVM-spur32? yes, I still didn’t merged with master. master still builds a regular cog vm. I’m working on spur64 branch now, here: https://github.com/estebanlm/pharo-vm/tree/spur64 https://github.com/estebanlm/pharo-vm/tree/spur64 the spur jobs are built against my repository for the moment. I see, that wasn't obvious. I know… because is till experimental :) And as Eliot says… is not *much* work… except when it is :) In fact, we were planning to release Pharo 4 (next week) with a Spur VM, but we didn’t finish all the small things around. So we will release next July (or around) a Pharo 4S (S, for Spur) with “official” spur support. We do not want to stay to much time in older versions. Also, our development process is different This explanation irritates me: Pharo 4 will be released soon with a Spur VM? And then around summer Pharo 4S? Isn't it a contradiction? no, Pharo 4 will be released *without* spur, then we will release a 4S *with* spur. Ok, that makes sense. than squeak, AFAIK… we drop backward compatibility in a regular basis. Which basically means we will move to spur and we will drop support for older versions. That's

Re: [Pharo-dev] Ways to do 32-bit arithmetics?
Hi Stefan, the point is that the code uses only 32 bits. The java code ands by 16r on each update to seed, and even if that's not necessary because seed is declared as int, it does show that we can discard bits above 3/ after each update. Therefore any use of seed in a left shift does not need alteration because high bits will be lost. The only case is in a right shift, where the sign bit will be propagated. So (assuming ^ defined as bitXor: and bitAnd: ; I'm on my phone, and that is arithmetic shift right) I believe that this will work: seed := ((seed + 16r7ed55d16) + (seed 12)) 16r. seed := ((seed ^ 16rc761c23c) ^ (seed as32BitSignedValue 19)) 16r. seed := ((seed + 16r165667b1) + (seed5)) 16r. seed := ((seed + 16rd3a2646c) ^ (seed9)) 16r. seed := ((seed + 16rfd7046c5) + (seed3)) 16r. seed := ((seed ^ 16rb55a4f09) ^ (seed as32BitSignedValue 16)) 16r. ^ seed as32BitSignedValue Eliot (phone) On Apr 3, 2015, at 8:04 AM, Stefan Marr smallt...@stefan-marr.de wrote: Hi Eliot: On 03 Apr 2015, at 16:47, Eliot Miranda eliot.mira...@gmail.com wrote: if seed is Andes with 16r when it is initialized then the Java code can be used to generate the next value and the sign conversion only applied once to yield the next value. That would eliminate lots of conversions and make the code readable, right? Sorry, I don’t understand you. In the Java code the `0x` is redundant/superfluous. It’s there because I ported the code from JavaScript. The important part is that Java has signed 32bit integers. So, it works as expected out of the box. The SOM version shows the explicit operations you need if you don’t have any knowledge about the underlying integer representation. In most SOM implementations, integers happen to be represented as 64bit values, that overflow into some form of big/large integer representations. The sign-related operations are necessary to get the correct shift and overflow semantics. I guess I could implement it easily on a 64-bit Spur image, but I haven’t looked into that yet. Marcus’ comment looks also useful, but it is going to be very slow… Best regards Stefan -- Stefan Marr INRIA Lille - Nord Europe http://stefan-marr.de/research/
