Installing a metalink on a subclass not overriding a method
by Peter Uhnak March 26, 2016

March 26, 2016

Imagine the following: I have a class âParentâ which has the following method Parent>>name: aString name := aString I also have a subclass of a Parent called Child. Now I would like to attach some behavior via MetaLinks for the method âname:â but only for the Child method, is that possible? Naturally I could just override the method and have Child>>name: aString super name: aString And then attach the metalink to that, but thatâs not nice because you have to create extra methods (which is extra work/code if Parent has more subclasses) Alternatively I could attach the MetaLink to Parent and do type-checking, but that would br very complex and error-prone (Parent has a rather wild family). Ideally I would like for the MetaLink to install to the child even though the method doesn't exist. Is that somehow possible? Thanks, Peter

by Torsten Bergmann March 25, 2016

March 25, 2016

Hi, played with the JSON API of Pharo FogBugz issue tracker with the outcome of another little Pharo tool that lets you: - login to FogBugz from Pharo - enter a string and search for according issues - open a browser on a selected issue in the result list (works on Linux and Win so far) The project repo is at: http://www.smalltalkhub.com/#!/~TorstenBergmann/FogBugz One can use the client also directly: |client| client := FogBugzClient loginUser: 'abc(a)def.com' password: 'secret'. (client query: 'UFFI') inspect. client logout You can download the tool in latest Pharo 5 (50660 or later) from catalog or by opening the Spotter and entering "FogBugz", wait and hitting ENTER. Attached is a screenshot. Enjoy T.

[ann] pharo consortium membership matching campaign
by Tudor Girba March 25, 2016

March 25, 2016

Hi, The Pharo Board is proud to announce a special campaign for attracting new Pharo Consortium members during 2016: http://consortium.pharo.org/web/Membership A new fund has been created from which the Consortium will receive the equivalent of one yearly membership fee for every new member, and the increment in yearly fees for every upgrading member. For example, if a new company joins the Consortium as a Silver member (2000 EUR / year), the fund will contribute a one-time amount of 2000 EUR to the Consortium. Similarly, if a company upgrades from Bronze (1000 EUR / year) to Gold (4000 EUR / year), the fund will contribute a one-time amount of 3000 EUR. This campaign will take place until the end of 2016, or until the fund is depleted. Currently, the fund totals 21000 EUR, a sum which is graciously supported by three companies: - LabWare Inc (http://labware.com) - ObjectProfile (http://objectprofile.com) - feenk gmbh (http://feenk.com) This is an exciting development that paves the way to attract more industrial interest around Pharo. Please help us by spreading the word about this campaign. Cheers, The Pharo Board

Re: [Pharo-users] OpenGL project
by Thibault Raffaillac March 24, 2016

March 24, 2016

Hi, Some progress on the OpenGL project: _ I read much of the sources around NBOpenGL, the architecture looks nice to me, so will keep it, but am actually considering to strip it to OpenGL ES 2! This is a subset of OpenGL, but is supported on more platforms (Android, iOS, RPi), and will be easier to maintain in the long term. _ A working minimal demo in C (https://drive.google.com/file/d/0B6Y_O5MtrUaEbXFjTGhUcTZwY3M/view?usp=shari…) _ SDL2 gave me some headaches (2~3 seconds to start & open a window, could not properly display the title bar, displays big ugly pixels on retina screen, could not test it in Pharo since it did not find library file). So I tried GLFW and LOVE IT (starts fast, handles the pixel density problem nicely, amazing documentation). I will work to bind it with FFI. _ Anybody else working on porting NBOpenGL? I am rather slow, so if we can sync work would be perfect :) Cheers, Thibault > ------------------------------ > > Message: 2 > Date: Sat, 12 Mar 2016 09:06:36 +0100 > From: stepharo <stepharo(a)free.fr> > To: pharo-users(a)lists.pharo.org > Subject: Re: [Pharo-users] OpenGL project > Message-ID: <56E3CE0C.1010907(a)free.fr> > Content-Type: text/plain; charset=windows-1252; format=flowed > > Check bloc under Moose in the CI > there is a little class with the binding. > > Stef > > Le 11/3/16 13:22, Thibault Raffaillac a ?crit : > > Hi, > > > > I would like to do a bit of OpenGL in Pharo, but it does not seem to work > > at the moment. > > > > Tried NBOpenGL with a spur image (50560): > > _ fails at installation from configuration browser (need to click again on > > installing to get all classes) > > _ demo "GLTTRenderingDemo new openInWorld" fails at NBGLContextDriver with > > error "No suitable implementation found for initializing OpenGL context > > for your platform" (running on a Mac) > > > > Tried with a pre-spur image (50496): > > _ same weirdness at installation > > _ demo fails at NBGLCurveRenderer with "MessageNotUnderstood: receiver of > > on: is nil" > > > > Is there a working demo available out there?

I believe that is indeed the only option (although, I thought at least, that you do not really have to create an account, that you can do just a payment through them, but that option is probably well hidden, or maybe gone). If you really want to pay another way, just opt for the invoice/pay afterwards option, and I'll send you an invoice and you can then pay by bank transfer. Sven

Customizing SmalltalkEditor context menu issue
by Ala'a Mohammad March 24, 2016

March 24, 2016

Hi, I'm trying to modify the context menu of the code editor through modification to SmalltalkEditor class >> smalltalkEditorMenuOn: testing the modification with (PragmaMenuBuilder pragmaKeyword: 'smalltalkEditorMenu' model: nil) menu popUpInWorld succeeds, and shows the final shape of the menu that I want (photo attached), but the actual one used by the system is messed up! (photo attached) I tried also to execute TextEditor class >> initialize, but that did not help. Another thing I did was trying to find senders and references to the SmalltalkEditor class >> smalltalkEditorMenuOn, and find none! (So who is calling that with a 'aBuilder'?), and the only implementation of it is the one I'm trying to update (more confusion - pardon the puzzled newbie). Attached are the photos for the original menu, target menu and the messed up menu. I'm using Pharo 4.0 from the official download for Linux from Pharo.org. my system is the following: Linuxmint 17.1 Rebecca 3.13.0-37-generic #64-Ubuntu SMP What I'm doing wrong? and/or what I'm missing? Thanks in advance for the help. Regards, Ala'a

ZnUrl>>#= - Why Require Same Classes?
by Sean P. DeNigris March 24, 2016

March 24, 2016

= anObject ^ self class == anObject class ... Most of the time, I've seen a test for #species, not class. This matters because I have a custom ZnUrl subclass that I'd like to be equal to a ZnUrl pointing to the same place. While we're on the subject, I'm not an expert on hashing, but isn't it a problem that ZnUrl>>#hash refers to #segment, which is not immutable? ----- Cheers, Sean -- View this message in context: http://forum.world.st/ZnUrl-Why-Require-Same-Classes-tp4886102.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
