Where do selected morphs get their emphasizing frame from
by christofbuerger Sept. 3, 2015

Sept. 3, 2015

Hello, tried honestly the whole day to figure out how morphs in world get their thicker frame from, when they are selected by a SelectionMorph. I wanted to copy/inherit that behaviour and make the frame for such selected items thicker than it is done by standard. Can anyone please give me a hint?! Thank you very much and Best Regards Christof -- View this message in context: http://forum.world.st/Where-do-selected-morphs-get-their-emphasizing-frame-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo on rhel 6.5 and libasound.so.2
by Emilio Oca Sept. 2, 2015

Sept. 2, 2015

Hi! I think I need some help here. I am trying to run a pharo seaside on a corporate RHEL 6.5 box. I downloaded this http://files.pharo.org/platform/Pharo4.0-centos.zip and deployed its contents on a directory. Gabe rights to execute and tried the first steps on this tutorial http://astares.blogspot.com.ar/search?q=headless but when running: ./pharo Pharo4.0.image save demo get this dependency error: pharo: error while loading shared libraries: libasound.so.2: cannot open shared object file: No such file or directory ./pharo --vm-sound-null Pharo4.0.image save demo give the same error message ldd bin/pharo gives linux-gate.so.1 => (0x00c36000) libasound.so.2 => not found libm.so.6 => /lib/libm.so.6 (0x00628000) libdl.so.2 => /lib/libdl.so.2 (0x00a1e000) libpthread.so.0 => /lib/libpthread.so.0 (0x007f4000) libc.so.6 => /lib/libc.so.6 (0x0014f000) /lib/ld-linux.so.2 (0x007b1000) I am not going to have rights to install libasound.so.2 unless its part of a supported red hat enterprise package. What are my alternatives? Is libasound within a supported package? can I have a vm without this dependency? Thanks Emilio

Problems to serialise object when using FileSystem memory
by Juraj Kubelka Sept. 2, 2015

Sept. 2, 2015

Hi, I am writing test case that uses following strategy: -=-=- | memory file | memory := FileSystem memory. file := memory workingDirectory / 'file.fuel'. FLSerializer serialize: {1. 2. 3} toFileNamed: file. -=-=- But it does not work because in StandardFileStream class>> #forceNewFileNamed: a "self fullName: fileName.â is called and it returns a string. So it tries to create the file in the default real file system; not in the memory file system. FLSerializer calls it in: -=-=- serialize: anObject toFileNamed: aFilename "Serialize the graph starting at the root object received and answers the FLSerialization object" StandardFileStream forceNewFileNamed: aFilename do: [ :aFileStream | aFileStream binary. self serialize: anObject on: aFileStream ] -=-=- using a stream neither work: -=-=- | disk file | disk := FileSystem memory. file := disk workingDirectory / 'file.fuel'. file writeStreamDo: [ :aStream | FLSerializer serialize: {1. 2. 3} on: aStream ]. -=-=- It produces an improper indexable object. The only code that works is that one: -=-=- | file | file := FileLocator workingDirectory / 'file.fuel'. FLSerializer serialize: {1. 2. 3} toFileNamed: file. -=-=- I think that using MemoryStore is a clean way to test code that stores contents into a file. How can I use FLSerializer and MemoryStore together? Thanks! Juraj

Yes arrows up/down handling in fast table is not perfect. Esteban told me there is a way to have this kind of filtering direclty in the small rectangle but I did not take the time to see how. I like the search field but maybe someone prefers filtering directly in the list items area Franck > To: pharo-dev(a)lists.pharo.org > From: stephan(a)stack.nl > Date: Wed, 2 Sep 2015 16:35:39 +0200 > Subject: Re: [Pharo-dev] Widget choice list > CC: pharo-users(a)lists.pharo.org > > On 02-09-15 14:22, Franck Warlouzet wrote: > > Hi, > > > > Some of you showed interest in a widget as the one which pops up to add protocol in Nautilus, but using FastTable.

Widget choice list
by Franck Warlouzet Sept. 2, 2015

Sept. 2, 2015

Hi, Some of you showed interest in a widget as the one which pops up to add protocol in Nautilus, but using FastTable. We started to build such one, it allows to bind specific action on click on a item, to have icon for items, to filter items etc. Examples show how to use it. It is still a beginning so there is probably some strange points or improvements to do, but if it appears to be useful to replace some widgets we can enhance it. Or it can simply show you how easy it is to build a fast table with a more complex data source, which would already be a good point. You can find the code in this repo : MCHttpRepository location: 'http://www.smalltalkhub.com/mc/FranckW/WidgetChoiceList/main' user: '' password: '' Feel free to contact me if you have questions. Cheers, Franck

[ANN] Pillar 1.0.0.
by Ferlicot D. Cyril Sept. 1, 2015

Sept. 1, 2015

Hello guys! I finished 5 months of internship into the RMoD team. I worked on Pillar and I am glad to announce the version 1.0.0! You can find an updated documentation of this version here : https://ci.inria.fr/pharo-contribution/view/Books/job/EnterprisePharoBook/l…. We decided with Damien Cassou to use Semetic Versioning from now (see: http://semver.org/) I will now explain the main changes I did on Pillar during my internship. For each new feature I added tests and documentation. I will begin with the changes of Pillar's structure - The configuration system is now manage by Cocoon (http://www.smalltalkhub.com/#!/~PharoExtras/Cocoon) -- We now use Magritte in Cocoon - I added Annotations : A syntax extension point - I added Transformers : A way to transform a document model before an export (to add a section structure in HTML for example) - Some small refactoring. -- Improvement of the template management -- Improvement of the Pillar model parameters - Improvement of the document model -- Now the figures and links are two different entity - I begun a PetitPillar (with PetitParser) in order to replace the old parser too complicated. Now I will talk about new features for the users - Improvement of the usability of Pillar under Windows - Beamer and Deck.js exporters - Annotations : -- To include a Pillar file into an other (${inputFile:path}$) (Example: https://github.com/SquareBracketAssociates/EnterprisePharo/blob/master/Ente…) -- To create new slides in Beamer and Deck.js (${slide:My Title|label=optional}$) -- To create columns into a Pillar document (currently works in Beamer, Deck.js and HTML) -- â¦ - Transformers -- You can now add a parameter "lineNumber=true" to a script and Pillar will transform them to add the line numbers -- You can now import a script from an other file (see the documentation of the scripts) -- â¦ - Improvement of the errors raised by Pillar - Addition of the inter-files links - Improvement of the title configuration for numbering - No need to make scripts anymore to use Pillar ! -- You can used "defaultExporters" in your configuration to do multiple export (see documentation) -- Pillar generate a script for LaTeX compilation (only for Unix for now) - Possibility to export everything into a different folder (simpler to clean after) -- And possibility to copy some support files For the two previous point you can take example on Enterprise Pharo (https://github.com/SquareBracketAssociates/EnterprisePharo) and Pharo Mooc (https://github.com/SquareBracketAssociates/PharoMooc) This was a really cool internship :) If you have some questions do not hesitate! -- Cyril

Ecstatic
by Ben Coman Sept. 1, 2015

Sept. 1, 2015

Hi Guille, I'm taking a look at Ecstatic, cloned from https://github.com/guillep/ecstatic (Thats a really cool name btw) I notice that ../_scripts/publish-gh-pages.sh does some fancy footwork to push the generated site to the gh-pages branch. I wonder if the following command [1] might be simpler... git subtree push --prefix _site origin gh-pages [1] https://gist.github.com/cobyism/4730490 cheers -ben
