Re: [Pharo-users] XSD handling in Pharo
I mean that XSD is XML indeed but the usage is for defining structures, and crafting all kinds of artifacts from there. I was involved with a project where a ton of XSDs were used to define business message structures. Reading XML is not giving us reading XML with XSD schema validation nor Classes generated from XSD files (as does Java JAXB). https://jaxb.java.net/2.2.7/docs/ Phil On Tue, Oct 1, 2013 at 10:10 AM, Norbert Hartl wrote: > > Am 30.09.2013 um 19:35 schrieb p...@highoctane.be: > > > XSD is not the same. > > > What do you mean? > > Norbert > > > Guess you want to do something like JAXB or schema validation.

Re: [Pharo-users] Morphic text filed plus autocompetion
Hi all, also notice that the default text entry widget has already an autocompletion feature. see WidgetExamples>>exampleTextEntryWithCompletionDialog You can find several uses of it. See EditorFindReplaceDialogWindow>>newFindTextEntryMorph as another example.

Re: [Pharo-users] XSD handling in Pharo
I have some partly-finished Squeak code that creates a schema-specific validating XML parser & generator (well, data objects that do this) given an XSD. My motivating use case is to enable quick support of new XML-based file formats. So, you would design your objects as usual, then run my schema parser, which would stub out objects to parse & generate the new format. Then you would write tiny conversion methods between your objects and the new ones. Poof! Support for a new file format. Partway through I found an enormous Java library that did something similar; it may be the one Phil mentions below. The one I recall was pretty big (13 namespaces) and I decided not to just port it because it seemed more complex than I thought was needed. On the other hand, it is finished, whereas.. I have been too busy to work on mine for several years now :( . So, I will hunt for it tonight & put the latest version somewhere other people can get & work on it. I don't remember what state it is in, but I never do so I think/hope it has lots of comments & tests for how I intended it to work. The other catch (besides it being half-finished) is, if/when I eventually start working on it again, I will turn it into a completely pedantic validating parser/emitter, because I want it to e.g. prevent XML injection without conscious thought from the developer using it. I am happy to help/advise anyone who wants this same goal to meet it, but if you want to add direct accessors or anything else that routes around the validation, please do so in a package that extends mine (in the same classes is fine) so that I can still meet my original intent when I eventually get back to it.

You probably want to do something similar to what we have done in Deltawerken-Framework. (on ss3) Stephan
[Pharo-users] Muiltple images / FFI
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. It works fine with one image but with multiple images it crashes with a seg fault/memory error when under user load. The error appears to happen when the wrapper code closes an OCI statement/connection. It appears with multiple images that they are allocating/de-allocating memory via the wrapper/OCI and over-writing each over. Is that possible ? Thanks
Re: [Pharo-users] Muiltple images / FFI
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 > 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.

Re: [Pharo-users] Muiltple images / FFI
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?

[Pharo-users] Thanks for Athens and Esse and a question about Freetype support for Athens in Pharo 3.0 image on Arch Gnu/Linux 64 bits
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

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...).

Re: [Pharo-users] Thanks for Athens and Esse and a question about Freetype support for Athens in Pharo 3.0 image on Arch Gnu/Linux 64 bits
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
