IIS and Pharo web service solutions
by Robert Kuszinger Aug. 25, 2016

Aug. 25, 2016

Hello! 1)--------------------- I've successfully worked out how to operate Pharo / Seaside web services behind IIS on Windows Server 2008 (R2) but maybe works on later editions as well. I could summarize it in a "HOWTO" if there is interest or even post it to include in a documentation. (Pharo as a service on Windows, IIS modules to install, how to make it and how to configure proxy / url rewrite) 2)--------------------- Since failed finding an usable binary for nginx uploader module on windows I worked out a method (not really a piece of software) how to use NeatUpload (.NET solution) together with Pharo/Seaside to receive hundreds of megabytes of uploads on Windows servers. If there is interest I'm also ready to document and post it here or somewhere. Please sign any interest here or in private email and then I'll create the docs. Thanks for the many help from many of you during the last two months :) Robert

Generating custom classes based on attributes from XML Document
by Peter UhnÃ¡k Aug. 17, 2016

Aug. 17, 2016

I have a XML like this <packagedElement xmi:type="uml:Class" xmi:id="EAID_4A" name="DCEdge" isAbstract="true">  </packagedElement> <packagedElement xmi:type="uml:Association" xmi:id="EAID_46">  </packagedElement> and I would like to generate UmlClass and UmlAssociation classes for this. I could use XMLPluggableElementFactory, however that only allows me to specify the target class only on the element's name, such as doc := (XMLDOMParser on: someXML) nodeFactory: (XMLPluggableElementFactory new elementClass: GenericElement; handleElement: 'packagedElement' withClass: UmlPackagedElement) parseDocument. However I need better granularity, because I would like to have a different class for 'packagedElement[xmi:type="uml:Class"]' and different class for 'packagedElement[xmi:type="uml:Association"]'. Of course I could use double visitors (so use the Pluggable stuff to get UmlPackagedElement) and then make another pass on it to get the final classes, however I would prefer to have to wanted class directly without the need to go through intermediate representation. Is there a way to do this? Thanks, Peter

Mea Culpa
by horrido Aug. 14, 2016

Aug. 14, 2016

Okay, so far, I've made two mistakes. First was my lack of sensitivity to cultural differences around the world. Now that I know better, I shall do better. Second was my failure to distinguish between different subgroups within the Pharo forum. The reason I chose Pharo forum to discuss my campaign was the fact that it is the most active Smalltalk forum there is. People who are interested in Smalltalk join the most active forum generally, and this includes not only Pharoers, but people from ESUG, Squeak, Cincom, Amber, Redline, etc. So, for example, when I appealed for contributors to the Redline project, I should've distinguished the target audience as those groups other than Pharoers. This was my failure and I own up to it. It is unfortunate that I must use the Pharo forum for this purpose. The Smalltalk community is so terribly fragmented that there is no universal Smalltalk forum to address, at least, none that is actually *inhabited*. Without the ability to address the largest number of Smalltalkers, the SRP cannot make any progress. I'm sorry, but I have to be blunt. If anyone can offer a practical alternative, I'd like to hear it. Otherwise, the SRP has only two choices: 1) Continue what it is doing on the Pharo forum, and be mindful of which group(s) I am addressing. 2) Fold up the campaign and leave the destiny of Smalltalk to the Fates. Without the ability to reach out to Smalltalkers everywhere, I am hopelessly disadvantaged.

Messages interceptions without using "halt"
by Steven Costiou July 24, 2016

July 24, 2016

Hello, i am not new to Pharo nor to the list but this is the first time i speak here, so : hi =) I started a phd a few month ago (with Alain Plantec) on context oriented programming and dynamic programs adaptation. I am using Pharo for my experiments and i would like to intercept messages sent to an object just before they get to their receiver. To be more specific, when #msg is sent to an object o, i want to be able to intercept it just before it is actually executed with the following objects at my disposal : the receiver (o), the message or selector, the sender. My objective by doing that is to (try to) change the lookup for a given method, and to be able to choose in which class the lookup will start. I have been looking a bit and it does not seem to be a "simple" way to do that in Pharo. Is that even possible and if so, any advice on where i should look ? Thanks, Steven.

Seamless

1. What is the status of this project (http://ss3.gemstone.com/ss/Seamless.html)? I see the last commit is in April. Does it "work"? 2. Can the communication be done securely? If I had two images each running on a server in a different physical location, could they communicate over something like SSL? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Seamless-tp4840907.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Failing to create a project on SmalltalkHub
by Victor RENE July 10, 2016

July 10, 2016

http://smalltalkhub.com/#!/~VictorRene I am trying to create a project on Smalltalk hub to save progress on the MOOC. But it fails with "incorrect username or password", and i can not logout. Okay, I can probably empty my browser cache but it's still incorrect behavior. Also, they say it's possible to use Git but they don't describe the setup. Any ideas? Thanks in advance.

Disabling welcome window
by Peter UhnÃ¡k July 10, 2016

July 10, 2016

Is there a clean way how to close or not open the Pharo 5.0 welcome window? Short of going through the stack and closing it (courtesy of Cyril) (SystemWindow allInstances select: [ :w | w labelString includesSubstring: 'Welcome' ]) do: #delete Thanks, Peter

parameters of the virtual machine
by Alexandre Bergel June 28, 2016

June 28, 2016

Hi, The Cog virtual machine expose some very useful parameters. However, some of them are a bit obscure to me. For example, what are the following parameters? What do they mean? 46 size of machine code zone, in bytes 59 number of check event calls since startup (read-only) 60 number of stack page overflows since startup (read-only; Cog VMs only) 61 number of stack page divorces since startup (read-only; Cog VMs only) Is there a way to get access to the cache? How many caches does Cog has? I guess it has - a method call cache (associating (object,symbol) -> compiled method - a cache for the JIT-compiled methods right? Are there other cache? How can I access them? In particular to query about their fill. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
