November 2018 - Pharo-users

problem when running without changes file (on windows)

by Baveco, Hans

I have a pharo 6.1 image (based on the Moose 6.1 image) containing a small application. I would like to distribute this without the source code. When I run the application with the changes file present all is fine. When running with the changes file removed, it mostly works ok but apparently the functionality for e.g. creating png (linked to Cairo?) is not available. The log file is attached. Now looking a bit further into this I observed that in fact all the 6.1 images I work with seem to have this same problem, e.g. when displaying Roassal graphs they display the red windows with crosses. Is this option to run without a changes files supposed to work in 6.1 (on windows)? What should I do to make it work? (noticed that there is no setting anymore for this) Hans

Re: [Pharo-users] Canonical download location for Pharo VMs

by Esteban Maringolo

Thanks Ben and Esteban. I got confused becasue /vm/pharo-spu32 modification date said 2014-11-14 , and I was looking for the most recent one. Now I realize that the directory modification date only changes when a file or folder is added directly to that directory and not one of its subdirectories. Looking at the PharoLauncher vm's directory I can see there is a 70-x64, 61-x86, etc, what is the criteria to determine which vm is for 6.0 and which for 7.0? The pharo.exe version says 5.0.0.0.

Re: [Pharo-users] MetaLink>>level: failing?

by Marcus Denker

More progressâ¦ in the latest Pharo7 this is now working... (#operation reifies the original operation): | link choice | choice := true. link := MetaLink new metaObject: [ :operation | UIManager default alert: 'Linked Version'. choice ifTrue: [operation value ]. ]; selector: #value:; arguments: #(#operation); control: #instead. (TestMetaLink >> #execute) ast link: link. TestMetaLink new execute. link uninstall. No need for using #level: as #operation for method execution is reifying the *original* method that would have been executed without the link. (this then is, too, what will be used to make finally âturning offâ instead links work correctly: if the instead link is not active (due to a condition or level), it will instead execute âoperation valueâ, that is, what would have been done without the #instead link present.

Re: [Pharo-users] Iceberg + BaselinOf + Metacello - how to manage interdependencies ?

by CÃ©drick BÃ©ler

Nobody knows ? I probably do/ask something wrongâ¦ My impression is that it is very difficult for a newcomer to get into Iceberg/Github (I tried to avoid GIT as much as possible and I understand why now ^_^)â¦ but still itâs a great tool. Just not that easy to "master" (there are several possibilities, orders for code loading). Please tell me if there is something wrong in what I try to do.

Re: [Pharo-users] Canonical download location for Pharo VMs

by Esteban Lorenzano

The canonical location is: http://files.pharo.org/get-files/70/ <http://files.pharo.org/get-files/70/> (for Pharo 7.0, there are siblings there for each version). There there are links to stable and latest. As is said in first page of file server, all the other locations are there for reference (even if what is in get-files references something else) :) http://files.pharo.org/vm/pharo-spur32/ <http://files.pharo.org/vm/pharo-spur32/win/pharo-win-i386-201811120325-a3f5…> Is one of this âreferenceâ places.

Hello Tomo, Thank you, very interesting project! BTW to load Jun4Pharo with UFFI OpenGL the expression is: Gofer new smalltalkhubUser: 'tomooda' project: 'Jun4Pharo'; configurationOf: #Jun; load. (Smalltalk at: #ConfigurationOfJun) project development load: #('Core'). There are only a few warnings during installation: This package depends on the following classes: TabActionButton NewListRenderer NewList Tab TabBar You must resolve these dependencies before you will be able to load these definitions: NewList>>#drawOnAthensCanvas: NewListRenderer>>#drawOnAthensCanvas: NewListRenderer>>#drawSubmorphsOnAthensCanvas: Tab>>#createClosedPolygonPathFrom:on: Tab>>#createLinesPathFrom:on: Tab>>#drawOnAthensCanvas: TabActionButton>>#drawOnAthensCanvas: TabBar>>#drawLinesOnAthensCanvas: TabBar>>#drawLinesWithSelection: TabBar>>#drawSubmorphsOnAthensCanvas: Most examples works also on Windows on Pharo 7. However the UFFI OpenGL freezes the image if launched on full-screen.

Canonical download location for Pharo VMs

by Esteban Maringolo

What is the canonical repository/ci to download the latest VM for Pharo? I'm trying to get pharo launcher to launch a 32 bit image in Windows, but it complains it can't determine the image version, so I'm trying to download the latest 32 bit VM for Windows to launch it manually, but https://files.pharo.org/vm/ doesn't have anyting updated, and links to a Jenkins that seems abandoned, same thing for https://github.com/pharo-project/pharo-vm, and https://github.com/OpenSmalltalk/opensmalltalk-vm/ doesn't link to a successful build. Any hints on how to download the proper VM for windows 32 bit or successfully configure Pharo-Launcher to determine itself how to do it? Thank you. Esteban A. Maringolo
