[Pharo-project] Polymorph
by Gary Chambers Jan. 6, 2010

Jan. 6, 2010

Given the integration of Polymorph with Pharo and the distinct direction that Squeak is going I am going to have to mark an end to Polymorph as an ongoing project, as such. Further changes/additions/refactorings will now be limited to Pharo and must be therefore done using the Slice system (will take a while to get to grips with as time allows). A final release of Polymorph will be made on SqueakSource, as time allows soon. This will be the last (allegedly compatible) version with Squeak, though I expect in its current state it is effectively not loadable into recent Squeak images. I'll try to get the time to make any changes via Pharo slices though I still like the modularity of packaging systems. Can't have both it seems. Polymorph is mature enough that, moving forward, most else can be done as additions rather that overrides. Perhaps an "extras" package? Thanks to all who have been involved with Pharo and helping us to move forward. Here's to the new baseline! Shame the StrikeFonts don't do all that they should... always a compromise of speed vs. functionality (c.f. translucent text). On a personal note, it would be nice to start to leverage the possiblility of an open approach to visuals, host windows etc. Valuable lessons have been learned and I think Pharo can provide a baseline for moving forward to a more flexible and performant ui substrate. Happy to work with you all to achieve that goal! Regards, Gary

[Pharo-project] Permutations and Combinations in SequenceableCollection
by John Toohey Jan. 6, 2010

Jan. 6, 2010

Hi, I'm trying to generate the permutations of a sequence of numbers. I've found # permutationsDo: aBlock, but this generated the permutation of the entire sequence. I want to do it in groups of 2. The #combinations: anInteger atATimeDo: aBlock method does what I need for combinations, but I cannot find the equivalent for permutations. Does something like this exist in the standard library, or in an external package. -- -JT

[Pharo-project] What about killing PharoWeb images?
by Mariano Martinez Peck Jan. 6, 2010

Jan. 6, 2010

Please, don't say "NOOOOO!" immediately. Read the mail carefully, take a deep breath and think cold. After working a couple of weeks in the Metacello configurations and now with Damien's scripts to build Dev and Web images, I came to the question: Do we really need a PharoWeb image? I will give just my opinions of why having PharoWeb images is not a good idea anymore 1) First of all, I don't like the PharoWeb name. Because it is not Web in general, it is seaside. So, in my opinion, a better name would be PharoSeaside. Maybe even new comers may think that the only alternative is seaside. You know I have nothing against Seaside and that I even use it several times. I would like to see AidaWeb images based in Pharo too. 2) Why to still have PharoWeb images if now Seaside images (at least the one click) are based in seaside ? In addition, when I develop in Seaside, I use Seaside images, not PharoWeb, and I think most people do the same. 3) Seaside images (or Lukas images for seaside) are MUCH more stable than the PharoWeb images. Why? Several reasons: 3.a) THEY know the dependencies of the packages, the versions, how to set up, the order of load, etc, NOT us. THEY are the experts in seaside, not us. 3.b) THEY really test their images before make then public. 3.c) We are "force" to release one release per month which has no sense. How says that Seaside is released once a month? That's bad because it means we are usually taking unstable versions. THEY know when a release should be done and when a release is stable or not. 4) Now I created all the Metacello configurations for the PharoDev image and I took me a lot of time. Because I am not the developer of any of those projects. So, I need to understand the dependencies, the order, the versions, etc. But why ??? If Seaside people have already done that, don't duplicate efforts. 5) The instability of PharoWeb images give to our public a bad impression. We waste all of out efforts of Pharo in that image. 6) The idea of Pharo is to be the vehicle. And that's exactly the Pharo role in the Seaside images. We don't need to build PharoWeb images. Even more, do we build PharoGlass images ? NOOOO. Why not ? Because Dale already prepare them and as HE knows much more about Glass than us, his images are better for Glass. 7) Tracking and managing issues always take time. Even analyzing a bug, say "we won't fix" and close it. With PharoWeb images we are having those kind of issues. 8) Our resources are limited. Why not to use them in more important stuff ? For example, building a better and more robust Dev image? Here is my proposal: 1) Completely remove the idea of PharoWeb image. Remove the links from the website and do not create Web images any more. 2) In http://www.pharo-project.org/pharo-download add a description explaining that now Seaside images are based in Pharo, so you can directly download that image. We can even explain a bit about seaside, and even if you want you can put a href called "PharoWeb" which links to the seaside image. However, I would rather call it "PharoSeaside". 3) Tomorrow we can have AidaWeb images based in pharo (please Janko!!) so we can just do the same and put the link to those images. 4) You may notice that Seaside images are a bit "different" than our Dev images. This is mostly due to the preferences, the theme and maybe some tools (ECompeltion instead of OCompletion, etc..). So, what I suggest is to prepare a little script that can be downloadable and those people who want a Seaside image but more "similar" to our Dev images, just run that script. So...what do you think? I would really like to hear your opinion about this. Cheers Mariano

[Pharo-project] What about having a blog with news in pharo website?
by Mariano Martinez Peck Jan. 6, 2010

Jan. 6, 2010

I know we discuss several times in ways to improve communication and documentation. But know I am being very precise: put a "news" section in the website. The website is written in Pier, so adding Blog should be really easy. Adding the Pier add on for colour highlighting would be even a dream. I think having a "news" section with RSS is a must nowadays in every software project. The mailing list has a lot of traffic (that's really cool) but there are a lot of people who cannot track it. So, having a place to read the news would be helpful. What kind of things we can post ? Examples: - I will announce soon the metacello configurations for external projects and after that the configuration for pharo. - ANN and news for external projects such as: Seaside, Metacello, Moose, Mars...whatever that runs on top of pharo - ANN for new dev images (after passing the beta test stage) - ANN of books - Now for example I can post that we have already started with the translation of PBE to spanish :) - Show progress and comments about Pharo sprints and coding sessions - Big decisions taken. For example if we agree to remove PharoWeb images - Success stories. Projects that goes on production or that have just started with Pharo - Comment lessons, presentations or conference where someone spoke about pharo - A lot of things more. I know the idea of the website is not to be too technical but I think these kind of stuff are not technical at all. Then we should see how and who post. In pier I subclass Blog with a new class that requires authorization for an admin users. Then there is a little component only for admins that let you browse the posts and authorize them. If you want I can send them to you. Cheers Mariano pd: sorry for the amount of "this kind of mails" that I am sending in the last weeks

After the update of VB-Regex (http://code.google.com/p/pharo/issues/detail?id=1639 ), the test SplitJoinTest>>testSplitStringOnRegex fails. Does somebody know what's wrong and how to fix it? Cheers, Adrian ___________________ http://www.adrian-lienhard.ch/

[Pharo-project] Building Pharo and Plugins for Mac OS X and Linux
by David Li Jan. 5, 2010

Jan. 5, 2010

Hi, I am new to Pharo and wonder if there is a step by step instruction on building Pharo for Mac OS X and Linux. I am working on a project that requires extension either through itself or via plugins. I have been seeing the mention of VMaker but can't find a good document about it. Thanks a lot for the help.
