[ANN] PharoDev-1.3-13173
by Mariano Martinez Peck April 27, 2011

April 27, 2011

Hi. IMPORTANT: This is not the final 1.3 release, it just one simple snapshot and one point. We all want a rock-solid Pharo 1.3 release, but that doesn't happens automagically. We all need to start using and testing the image before they are release. It is for the better of all of us. The more we test the more stable will be the release. So...we need your help. What you can do? 1) test test test test test. Use it. Take this image and use it for your regular work. 2) report bugs: http://www.pharo-project.org/community/issue-tracking 3) propose fixes: http://code.google.com/p/pharo/wiki/HowToContribute 4) Fix errors/failures tests 5) Load your OWN packages and projects now. Don't wait until Pharo1.3 is released and then ask "uuhh what happened to XXX? you removed? ohhh but I use it". 6) Do you maintain Metacello configurations? ok, if you test your project and works correctly in Pharo 1.3, please update (or create if you don't yet have it) the #stable, 7) Do you maintain packages included in Pharo? please check we are using the correct versions 8) I would like to see people testing AidaWeb, Magma, Fuel, Moose, DBXTalk, Seaside and all its friends, Zinc, FileSystem, etc, etc, etc. Pharo-1.3-13173 should work with Interpreter VM and with Cog. For Cog I recommend to download the last one from Eliot's page: http://www.mirandabanda.org/files/Cog/VM/ Two little warnings: - The Transcript is read only....and it will probably be roll backed to the previous one - if text editing looks weird....it is Lukas's fault ;) http://www.youtube.com/watch?v=fTMX1f8Lu5w Ok, the image is here: https://gforge.inria.fr/frs/download.php/28517/Pharo-1.3-13173.zip<https://gforge.inria.fr/frs/download.php/28517/Pharo-1.3-13173.zip> And it was build by Hudson: https://pharo-ic.lille.inria.fr/hudson/view/Pharo/job/Pharo%201.3/111/ Best regards, -- Mariano http://marianopeck.wordpress.com

This is impossible and, in the end, not a good idea. We can not be compatible forever, was this would mean that we can not improve anything. e.g. imagine someone would fix the VM to be better. (e.g. a modern object format). Do you really request to then *not* do this change because this VM could not run old images? (and new images would not run on old VMs?). Do you want to have a Future or be compatible to the Past? Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

My 2 cents on this topic: user interface consistency cannot be underestimated. I called these 'leds' unit-test icons because thats what they are (in my mind and I guess also for a lot of other people). So using them for anything else is not a good idea at all. Alex' proposal seems (to me) a much better idea. On 23 Apr 2011, at 13:05, Alexandre Bergel wrote: > I agree with you. The browser is not yet a replacement for manual editing.

How to access a text entry?
by DougEdmunds April 26, 2011

April 26, 2011

I am trying to model a simple GUI from the UITheme class exampleBasicControls. In that method, there's this: 'Text Entry'->(dialog newTextEntryFor: (ValueHolder new contents: 'Hello') getText: #contents setText: #contents: help: 'This is a text entry'). which creates a textbox, with the default value of 'Hello'. How do I access what's typed into the 'Hello' area so I can use it in code? I'd like to use it this way: 1) enter something into the box. 2) when done, click a button which does something with the new value (but I don't want to close the window). For example, I type in '33' and click a button. Some code receives that value and adds 1 to it, then prints out the result 34 on the Transcript. -- View this message in context: http://forum.world.st/How-to-access-a-text-entry-tp3474689p3474689.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

However, if they are working, we can just let them in case someone still use them, and when MetacelloBrowser comes in, we remove Metacello-OB. Do you know more or less if Metacello-OB is working or no? is anyone using Metacello-OB? speak up now! :) Thanks -- Mariano http://marianopeck.wordpress.com

Metacellobrowser feedback
by Johan Fabry April 23, 2011

April 23, 2011

Hi all, I'd like to give a bit of feeback on the metacello browser. First some context: I am aware of the core concepts of configuration management, but because of lack of time I never got to learn Metacello. So I thought this browser would be ideal for me, I gave it a go, and I'd like to report on my experience. The first try did not work at all for me, because I started with a configuration that is too complex. So lets start with the second try, something simpler, and first get that sorted out before we do the complex one. Here we go: I have a SqueakSource project TraitsApplication with one package TraitsApplication which contains TraitsApplication and TraitsApplication-Tests categories (and the former contains a TraitsApplication class :-P ). Following the prompts in the browser I was able to make a configuration and save it to SqueakSource, without any real problems. So the cool thing is, I made my first Metacello config today and it even works :-) One issue is how to load my creation. I am used to a big do-it that gets the config via Gofer and contains '(Smalltalk at: #ConfigurationOfFoo) perform: #loadDefault'. Many configs do it like this, as a user I considered it a standard convention. But this turns out not to work, because no loadDefault has been defined. Perchance I remembered how I had to load MetacelloBrowser '(ConfigurationOfMetacelloBrowser project version: #stable) load' and adapting it to TraitsApplication (not forgetting version:#development) made it to work. So, the question: why is there no #loadDefault generated, nor an obvious way to specify what the default should be? (At least for simple cases of the configuration, like this one) The second issue is the UI. It is confusing at times, there are multiple issues and I list them in random order - Why can I not click on '+Configuration' when there is no configuration selected in the left hand side? - What do the unit-test icons at the left of the configs and baselines-versions-... mean? I turn them green by double-clicking on them, which also gets me an inspector on an empty collection. Huh? - The context menu is too big and confusing. It should be subdivided and ordered by group. Submenus are in order I think. - What are groups? The help menu does not enlighten me. Next up: making a config for AspectMaps (the first thing I tried and that did not work). But this is for another day ... -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile
