[ANN] Bootstrap for Seaside3 project (Release 0.1.0)

by Torsten Bergmann

Hi, there are various frameworks out there helping you to ease common tasks in web development. One of them is Bootstrap (http://getbootstrap.com) that is used more and more to easily style web sites and web applications. We had wrappers for Bootstrap supporting Seaside in the past already: - the TwitterBootstrap project on SS3 from the Seaside team - the TBootstrap project from Gaston Dall Oglio Unfortunately these projects are not up to date with the latest Bootstrap version, not covered by tests, had no docu or examples, no CI, ... To provide better support for Bootstrap and Seaside3 development I created a fresh project called "Bootstrap for Seaside" (or "Bootstrap" for short). This new project is - nearly feature complete regarding components (Nav, Navbar, Jumbotron, Buttons, Alarms, Layouts, ...) - uses the latest Bootstrap libraries (http://getbootstrap.com) - covered by more than 160 tests - completed with an example browser that shows Bootstrap components and according Smalltalk code - available at STHub (http://smalltalkhub.com/#!/~TorstenBergmann/Bootstrap) - documented (see mentioned project website on STHub) with docu support for PharoOnlineHelp and catalog - controlled by CI (https://ci.inria.fr/pharo-contribution/job/Bootstrap/) - easily loadable using config browser in Pharo 2.0 Attached are some screenshots from the project itself. More details can be found in the more docu at the project site on SmalltalkHub. Just scroll down at the info page provided there. You can easily load it in a fresh Pharo 2.0 as "Bootstrap" from the config browser. It loads Seaside3 as a dependency. After loading evaluate ZnZincServerAdaptor startOn: 8080 to start the webserver and go to http://localhost:8080/bootstrap to browse the samples. Feel free to use it for your next Pharo/Seaside/Bootstrap based web project and thanks in advance for any contribution you may give to the project in the future. Bye T.

Re: [Pharo-users] XSD handling in Pharo

I tried to load this but Esse loads from http://ss3.gemstone.com/ss/Esse, while Esse.2 (package) hasse a number of Esse.2.* versions which are **empty** :-( So, p := EsseProject new doesn't work as there is no EsseProject class loaded. Looks like Esse has the main classes and Esse.2 has the EsseProject, which just isn't there. Anyone to move all of this to SmalltalkHub BTW? With MIT licence? Phil

I discovered that the LineMorph was still around in the image. I kind of like that Morph. Esse looks very nice indeed. I'll try it out for a presentation this week (nothing better than deadlines to make one learn fast...).

Hi > Yesterday I was again take a look back into pharo. I really like zoomable interfaces and despite that most of my hobby programming today is done on python/web2py I would like to keep pharo on the radar and not loosing touch with the language and community. So I would like to make some minor experiments about prezi like presentations on using Esse[1][2] and Athens. I just want to thank you about that projects and let you know that support for Athens was really smooth on Pharo 3.0 Thanks this is a good feedback. I looked at the video and I saw that not everything is displayed using Athens, so if you want to help we should convert some morphic rendering to athens. > > [1] http://gsoc2012.esug.org/showcase > [2] https://dl.dropboxusercontent.com/u/792245/Esse%20project.mp4 > > There is a minor glitch about freetype fonts support that I image is related with the path of the for 64 bit systems as a 32 bit library.

Hi, Yesterday I was again take a look back into pharo. I really like zoomable interfaces and despite that most of my hobby programming today is done on python/web2py I would like to keep pharo on the radar and not loosing touch with the language and community. So I would like to make some minor experiments about prezi like presentations on using Esse[1][2] and Athens. I just want to thank you about that projects and let you know that support for Athens was really smooth on Pharo 3.0 [1] http://gsoc2012.esug.org/showcase [2] https://dl.dropboxusercontent.com/u/792245/Esse%20project.mp4 There is a minor glitch about freetype fonts support that I image is related with the path of the for 64 bit systems as a 32 bit library. The same happen some time ago with cairo, so, if someone knows where to find to declare the path for that fonts I would really appreciate that. Cheers, Offray

Re: [Pharo-users] Muiltple images / FFI

by Guillermo Polito

Hmm, pharo processes should share no memory at all. Then the question is, is Oracle library doing something strange? Maybe the library suggests to be used in some special way for your setup?

Re: [Pharo-users] Muiltple images / FFI

by ClÃ©ment Bera

Hello, How did you bind your native library, with FFI, alien or NativeBoost ? I guessed FFI but I'm not sure. Did you try to run all the images on several VM (1 VM per image) ? If so, did it solve the problem ? What version of the VM are you using ? (Evaluate Smalltalk vm version). Retry with the latest stable version of the VM and check if it does not solve the problem (latest stable here: http://files.pharo.org/vm/pharo/, select your os then download stable). I'm not sure about the overwriting problem, I'll ask other people on thursday (if they don't answer). 2013/10/1 <recursive68(a)gmail.com> > Hi, > > I have an app (seaside) that is configured with multiple pharo (1.3) > images behind an apache proxy, using a FFI wrapper to a OCI native library > to connect to Oracle.
