What did you finally find out for speed up? > Hum, some crappy things. For example, to manage the z-index of the bubble talk: - a loop to draw all the morph - a second loop that select the buuble (isKindOf: bubble !!!) and draw only the bubble. These two loops are in the same method and called on each step... for a bubble that appears only 1 or 2 times in an application Removing the second loop makes Phratch 2x faster. I am continuing to clean that. I also find the problem with click-event. Now when I click, it works fine !

Re: [Pharo-dev] Image's size in pillar

by Natalia Tymchuk

Hello, I have one more question. I write the subscripts like it is written: @@subscript@@ and in html file it works, but in pdf not. For example: it is written x k + 1 instead of x k + 1 . Will this be fixed on pillar side, or what should I do to fix it on my side? Best wishes, Natalia

Please put energy into item #2, and postpone again until it's ready if necessary. :) Those who already use Pharo 3 know the risks of using a beta version, so they can wait until the release version is ready. :) Regards!

Phratch Website + version 3.0 in dev

by jannik laval

Dear all, I am pleased to announce Phratch website: www.phratch.com Thanks to the support of ESUG, it is possible to make visible this wonderful project. For now, what is available on the site: - a presentation of Phratch (you can refer to it now) - installation files, there is a portable version for Windows, Linux, MacOS. - tutorials - block documentation: generated from a Phratch image ! - Some elements for Jetstorm (a lot of new articles will come soon) - a category with news Now about the versions, I am developing the version 3.0 Why this number ? Why a third version in one year of work ? It is clear that a lot of work is already done. Each version represents strong changes in the architecture. - version 1.0 is the port of Scratch + BYOB + Panther in Pharo. It is working but not extendable. - version 2.0 makes Phratch really extendable. We can develop our own block for everything in Pharo. I also make Phratch more modular with the use of Pragmas for some menus, declaration of blocks... It is available only in Pharo 3.0. There are some languages available, I hope more people can translate in other languages (http://www.phratch.com/archives/612) - version 3.0 is the version in development. What is new here: Before this version Phratch was really slow. I am cleaning the code, and now it begins to be fast, really fast ! We also begun to write tests. I am really happy to have the support of ESUG and Pharo. Thanks to the community to make Pharo as usable as it it, it makes our dreams possible.

[ANN] Pharo and ST books page (as another Seaside demo on PharoCloud)

by Torsten Bergmann

There are some free Smalltalk books collected by Stef in the past. http://stephane.ducasse.free.fr/FreeBooks.html Yet this page is often unknown to people. I therefore converted them to a more Seaside like demo using the Bootstrap project at: http://pharo.pharocloud.com/pharobooks as part of the Pharo/Seaside/Bootstrap demos at http://pharo.pharocloud.com Code for this is on http://smalltalkhub.com/#!/~TorstenBergmann/PharoCloud. I would suggest that we create a shortlink "books.pharo.org" for http://pharo.pharocloud.com/pharobooks to it - any takers? This way we can tell people: "Ahh you want to get Pharo, just use get.pharo.org" "Ahh you want to download Pharo, just use files.pharo.org" "Ahh you want to enhance Pharo, just use bugs.pharo.org" "Ahh you want to control Pharo, just use ci.pharo.org" and now "Ahh you want to learn Pharo, just use books.pharo.org" to be continued ... Kudos to Stef for the collection and to Mike for being able to host a demo on pharocloud. Have fun T.

Font problem is still there

by Alexandre Bergel

Hi! We have had experience a problem with font when using Athens to display text. Apparently, this is due to some recent version of Athens. We have to load the following packages to not experience the problem: Name: Athens-Core-MarcusDenker.34 Author: MarcusDenker Time: 5 July 2013, 10:59:47.206954 am UUID: e844b2d4-b091-42a4-9be0-17101dcdbd30 Ancestors: Athens-Core-MarcusDenker.33, Athens-Core-ErwanDouaille.33 Name: Athens-Cairo-MarcusDenker.51 Author: MarcusDenker Time: 26 August 2013, 4:03:06.190096 pm UUID: 9e1bfddb-67f7-4a36-864d-11060b8b6881 Ancestors: Athens-Cairo-SebastianTleye.50 This is a _major_ problem to us and apparently there is no simple solution. These kind of problem may force us to move to seek for an alternative to Athens.
