PetitParser Help
by Mohammad Al Houssami (Alumni) March 14, 2013

March 14, 2013

Hello Everyone I was going over PetitParser part on the pharo by example book. http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/PetitParser.… It was all going good until page 11. Script 1.19is for creating the class so this was fine. You get an ExpressionGrammar class with all the needed variables, but what about script 1.20? Where does this script go? I understand what the code does. It is describing a grammar for mathematical expressions by defining what everything is and the rules of the grammar. I am not sure where shall I put this script to run it. In earlier examples I was using the workspace. Any help is much appreciated. Mohammad

How to deploy a Pharo 2.0 Desktop application?
by Torsten Bergmann March 14, 2013

March 14, 2013

>> But making it non-resizable, I don't think so. > >you can change the size (and the title), see DisplayScreen class>>#hostWindowSize: and around, but you cannot make it un->resizable. For Windows I wrapped some methods for changing the window style. This is already within NativeBoost in Pharo 2.0: NBWin32Window getFocus setNonResizable The VM opens the window by default in resizable mode and with this you can change the style to the styles you want. Look how it is done and check other styles: http://msdn.microsoft.com/en-us/library/windows/desktop/ms632600(v=vs.85).a… Downside is that you have to do it again at each image startup. Another solution is to change the hardcoded default windows styles in the C sources (if you compile a new VM anyway). Bye T.

ZnWebSocket and Seaside ZnZincServerAdaptor
by Esteban A. Maringolo March 14, 2013

March 14, 2013

Hi, Is there a way to use the same server Seaside is using to plug a ZnWebSocketDelegate into it? The ZnZincServerAdaptor runs by default as the root delegator for its server (at whatever port it was started), but I was wondering if there is a way to reuse the same server Seaside (on top of Zinc) is using, to plug different WS handlers. By now I'm just using another server to run the WS, which is no big deal except to open an extra port in my server.

GSoC13: Google Summer of Code started, your ideas please!
by Janko MivÅ¡ek March 13, 2013

March 13, 2013

Dear Smalltalkers, Time for your cool project ideas on this year Smalltalk GSoC! For now just express any idea you have here on the mailing list. Later we will together develop it to be in complete format together with two mentors needed. Deadline is end of Mart, so we have three weeks of time. To see how fully developed ideas look like please look at 2012 ones at: http://gsoc2012.esug.org/ideas. Note also that students yourselves can propose a GSoC project. So if you like to be a student on this year GSoC and have a nice idea, don't be shy and propose it here! The community will listen you and guide to the really nicely proposed project. Last year 6 student proposed projects were accepted and finished successfully! For the community, start looking around for students. Think about how to approach the universities near by you, do you know who to contact there, etc. We are namely preparing an application to this year Smalltalk Google Summer of Code under ESUG umbrella, as last year. If accepted, Google will pay few stipendiums to students on our Smalltalk projects. More on our special Smalltalk GSoC 2013 website: http://gsoc2013.esug.org I'm specially inviting mentors of all past GSoCs to rejoin the mentors mailing list, where we discuss all details about this year GSoC: http://groups.google.com/group/smalltalk-gsoc-mentors While students interested on GSoC please join a special Smalltalk GSoC mailing list for you: http://groups.google.com/group/smalltalk-gsoc-students Best regards Janko -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

March 13, 2013

Hi list, How does one get the references to a class in Nautilus? In RB it used to be control+N, now I can't find it anywhere, not even in the context menus... Thanks! Bernat. -- Bernat Romagosa.

RFBServer>>#encryptPassword: wipes the password thats passed in and I'm confused why that's ok.
by Paul DeBruicker March 13, 2013

March 13, 2013

IF I load the RFB package from lukas's site[1] (Pharo 1.4, recent enough VM, linux) and set the RFB server's fullPassword like this: MyObject>>startRFB RFBServer current setFullPassword: self rfbPassword MyObject>>rfbPassword ^'1234' After that send the source of rfbPassword shows '1234' but the bytecodes show that it is '' and the apparently empty string is 8 bytes long with each character being (Character value:0) #setFullPassword: uses #atAllPut: to set the value of #rfbPassword to 'Character value: 0'. My concerns are these: 1. Using the current implementation its impossible to stop and restart the RFB server with a default password programmatically. 2. The implementation is not idempotent when starting/stopping. 3. I don't understand the security consequences of removing the part where the password sent to #encryptPassword: is set to NULL characters. Is wiping the values of the #rfbPassword method necessary for security reasons? I assume that setting the RFB server to only accept connections from localhost and using X forwarding would take care of most of the risk of having a string literal in the image. Or- should I be accessing a default RFB password from another source than a class side method in the image? Is there a standard practice for starting and stopping the RFB server in Pharo 1.4 where the RFB server is up and down during the time the image is up? Thanks for any advice Paul 1 - The change was from this package: RFB-MiguelCoba.26.mcz from this repo: http://source.lukas-renggli.ch/unsorted

about communication and collaboration
by StÃ©phane Ducasse March 12, 2013

March 12, 2013

Dear Pharoers last january I visited another lab and I realised that the Pharo Team was not good at systematically telling what we were doing. I got quite frustrated by that situation, especially because we are working hard to build a better system. So we brainstormed when I came back and we want to apply the same ideas that what we do for our research team. For our research team every monday we get a simple mail that tell us to say to the others what we did and what we plan to do. Simple, easy. Then after people of the rmod team can discuss if they want more. We want to do the same with pharo. Often this is not that we are not doing things. Often we are doing boring, tedious stupid but $^%&&*^ important tasks and we want that you know it. In addition we want to share on what we are weekly working. So that you can be more engaged to join and collaborate with us. So we will launch an experience and see. For now we will send a notification every two weeks. the Pharo Team

NeoCSV/NeoJSON and encodings
by Esteban A. Maringolo March 12, 2013

March 12, 2013

Hi all, Sven, I would like to know what is the proper way (steps) to parse a UTF-8 encoded CSV file, which will store most of the strings into domain objects instVars which will get mapped back to JSON and send trough the wire by means of a Seaside RESTful Filter. I haven't specified any encoding information during the input or the output, and then I'm not seeing the right characters in the inspectors (I expected that), nor in the JSON output or the Seaside HTML output. The Zinc server adaptor has its default codec, it is, utf-8. -- View this message in context: http://forum.world.st/NeoCSV-NeoJSON-and-encodings-tp4676067.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo 1.4 Unable to download from HTTPS Monticello repository
by Federico.Balaguer March 12, 2013

March 12, 2013

Hello I am having problems downloading packages from a HTTPS Monticello repository. The image has Zodiac installed. I am able to upload versions but I cannot download them. I am able to download the packages from a web-browser, Using the Monticello Browser I can browse the content of the given repository. When I select any package on the repository a debugger pops up: "MNU: Character>>bitOr:" I do not see how to fix the problem, at some point, MCMczReader>>zip calls Zip>>readFrom: calls Zip>>readEndOfCentralDirectoryFrom: calls ReadStream>>nextLittleEndianNumber: calls SmallInteger>>bitOr: with a Character as parameter which makes the <primitive 15> to fail. I can try to fix the problem but I would need a little help to understand the root of the problem.
