Problem fetching a baseline
by Vitor Medina Cruz Dec. 30, 2017

Dec. 30, 2017

Hello, I am experimenting with Metacello but I am having problems to test my configuration. First I thought the problem was with my configuration, but after serveral atemps I tried to fetch an arbitrary Baseline from default image: Metacello new className: 'BaselineOfTonel'; baseline: 'Tonel'; fetch. And I got the following error: "Could not resolve: BaselineOfTonel [BaselineOfTonel] in C:\Users\Vitor\Documents\Pharo\images\Pharo 6.1 (stable)\pharo-local\package-cache http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main/" Which is the same I got with my own project. I tried using 'repository:' also, but got the same error. Am I doing something wrong? cheers, Vitor. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Livre de vÃrus. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…>. <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Package reference in Monticello
by Vitor Medina Cruz Dec. 29, 2017

Dec. 29, 2017

Hello, Is it possible to reference a 'package with tag' as a package in a Monticello configuration? Such packages don't have a folder in filetree, so, for example: Package1-Tag1 Package1-Tag2 There will be only one folder in filetree named Package1 and classes from Package1-Tag1 and Package1-Tag2 will be inside Package1and have, respectivelly, category Package1-Tag1 and Package1-Tag2. If I wanna use Iceberg, Git and reference Package1-Tag1 and Package1-Tag2 as packages in a Monticello spec, will I have to promote them to a full Packages?

image/vm mismatch on raspberry pi model 3
by Greg Lewin Dec. 29, 2017

Dec. 29, 2017

Hi, Having copied a viable pair of image+changes and its associated sources file to a pi 3, in the same directory as the directory from the zip file (from https://ci.inria.fr/pharo/view/RaspberryPi/job/RaspberryPi-Publish/ws/64.zip) containing the VM code for a rpi, on running ./PharoS Pharo6.1 I get the message "This interpreter (vers. 6505) cannot read image file (vers. 6521)." How does one ensure a match between VM and image+sources on raspberry pi ? I have also tried one image pair from an earlier version and get a similar message. thanks Greg

Learning Morphic
by T.D. Telford Dec. 28, 2017

Dec. 28, 2017

I am primarily interested in graphical shapes and bit maps (for fractals). I want to put graphical shapes or bitmaps in a window or bordered area. I have not been very successful in finding documentation about how to do this in Morphic. In contrast, I find the documentation for Roassal easy to find and to the point. Perhaps someone could point me to Morphic documentation (or supply examples) on my area of interest that includes a lot of examples. Thanks.

Is there a way to set form colours using a 'fuzzy' option?
by Andy Burnett Dec. 28, 2017

Dec. 28, 2017

I have an image with black text, and a white background. I would like to set the white pixels to transparent. I worked out how to do this, but of course it leaves me with a white halo around the text, where the border pixels are almost white, but not quite. In googling about this, I discovered that RMagick has the idea of replacing pixels which are almost any particular colour. I didn't find anything similar in the ColorForm class. Is there a way to do this within Pharo? Cheers Andy

in-image pharo user objet ?
by CÃ©drick BÃ©ler Dec. 28, 2017

Dec. 28, 2017

Hi all, For now, it is asked (by convention) a string containing our first name and last name (when code is submitted). Just wandering if you could have a better representation of a user of a Pharo image. Could we imagine a user id instead ? That shouldnât be heavy to deal with and eventually one could add more functionalities (one being the authentification to a pharo based application). The difficulty is to find a proper universal user id. I would have used something that encode date and place of birth in the id but it suffers some privacy related issues. Any ideas ? Another question is if an image may be used by several people ? To me allowing one user is ok for a developer image but it might be interesting to switch user spaces if itâs for a pharo application ? Cheers, CÃ©drick

pharo 64 bits on mac os X - El Capitan
by Renaud de Villemeur Dec. 27, 2017

Dec. 27, 2017

Hi all I want to run pharo on Mac Os X. It is on old hardware, and thus, I cannot upgrade to latest version of MacOsX. I am trying to run in on El Capitan - v 10.11.6. When I start pharo from the command line, I have this error: $ ./Pharo Illegal instruction Tue Dec 26 11:12:55 2017 VM: 201707201942 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Date: Thu Jul 20 12:42:21 2017 -0700 $ Plugins: 201707201942 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Abort trap: 6 I am using latest 6.1 64bit link from pharo web site. If I am using the command line install with curl, I have the following result: ./pharo-ui Illegal instruction Tue Dec 26 11:19:49 2017 VM: 201707201942 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Date: Thu Jul 20 12:42:21 2017 -0700 $ Plugins: 201707201942 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ ./pharo-ui: line 11: 991 Abort trap: 6 "$DIR"/"pharo-vm/Pharo.app/Contents/MacOS/Pharo" "$@" Any hint ? Or should we specify a minimal version of mac os X for 64 bit version ? Thanks in advance for your help Renaud

Breakpoints in Pharo
by Andrei Stebakov Dec. 27, 2017

Dec. 27, 2017

Can I expect that break points in Pharo work in the same way as in Visual Works? When I set a break point in Pharo (6.1 on Windows), it displays a red dot with an exclamation mark and when I send this message to an object, the debugger doesn't get invoked.

Usability issues with Calypso
by kmo Dec. 27, 2017

Dec. 27, 2017

I have been keen to use Calypso (I love the way it shows inherited methods) as my browser but I am finding some usability issues. It may be just me but some things I find off-putting. I don't really like the way that adding a new class is done by a new tab that appears now and then in the editing area. To my mind the Nautilus way of launching a dialog to create a class seems more natural - and opens the way in future for a class creation wizard - something that can't be done in a code window. If we have to do it in a code tab then it would be better if the tab remained there all the time - I don't like the way it appears and disappears. It takes a while to learn what to click to do this. Also, all class creation presumes a subclass of Object in Calypso. i miss the ability in Nautilus to select a class and immediately create a subclass of it. Am I missing something here? Is there a way? On the topic of my ignorance - what is a /project /in Calypso? How do you create one? And what does realize do? Also I think that the pop up menus could be subdivided into categories rather than present all the options in an unbroken list. And the order of options seems odd. To my mind/ senders /and /implementers /are two menu options that should always go together - not be separated by/ rename/ and /move to class side/ et cetera. Just my two cents. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
