Iceberg working with forks - can it be easier?
by Tim Mackinnon Feb. 19, 2019

Feb. 19, 2019

Hi guys - Iâve spent a few hours scratching my head trying to understand why some of my Pull Requests to a project I had forked kept showing my previous commits when I thought I was all caught up. It suddenly dawned on me, that when I had forked, and then done some work and then submitted a PR, and then applied it upstream that my fork is now no longer in sync with its upstream counterpart. Having not done this in ages, it took me a while to then realise I have to do some git stuff to get it back in sync e.g. (and I think Iâve got this right) git fetch upstream (or whatever name you gave it) Git checkout master Git merge upstream/master So I guess my question is - wouldnât it be helpful if this was a command in Iceberg? It seems quite common to fork a project (I think this is still recommended for pharo itself isnât it?) - and then at some point you need to catchup with that origin again? Or am I missing something? I guess lots of stuff can go wrong - but if it does - youâd still get the same problems on the command line. It just seems that for normal situations - it would be handy to run this straight in Pharo. Thoughts from the git experts? Tim

How to uncache Commander menu items
by Tim Mackinnon Feb. 19, 2019

Feb. 19, 2019

I was going to write this question - but Denis pinged me on Discord - however I thought I would lob this into the list in case someone else hits the problem and is searching for it. (Maybe I should stick this in Calypso or Commander faq). My problem was that I had built a sub menu in Calypso and specified the order of the menu items as described in the docs. packageContextMenuActivation <classAnnotation> ^ CmdContextMenuActivation byItemOf: ClyExercismMenuGroup order: self contextMenuOrder for: ClyTaggedClassGroup asCalypsoItemContext However when I went to add some icons and change the ordering I was finding that my menu wasnât updating. There are 2 solutions (one better than the other). The brute force way is: CmdContextMenuActivation resetCache. The elegant way was to add an annotation to my menu ordering method contextMenuOrder <classAnnotationDependency> ^1 Tim By the way - to see what icons you can use in your menus, inspect: ThemeIcons current

How do you avoid loading master code which is indirectly referenced by a version in the baseline?
by Sabine Manaa Feb. 19, 2019

Feb. 19, 2019

For test and deployment, I have to be sure that I know exactly which versions I load and I have to be sure to be able to load exactly the same code again. I do not speak from my projects but from the projects I use. I found myself asking people again and again to set tags in their projects and being surprised again and again by changed code even though I am trying to load versions (with versions I mean NOT #stable or #master but like v2.2.2). The reason for this problem I then have, is that often in baselines with version numbers (e.g. v2.2.2) other projects are referenced but as master. So in consequence, I load version but get master from another project which is referenced indirectly. For me, that this is not good at all. I was wondering that this seems not to be a problem for others. I found out that I can put a lock in my baselines preLoadDoIt for those indirectly referenced projects. Examlpe Artefact v1.0.1 https://github.com/pharo-contributions/Artefact/blob/v1.0.1/src/BaselineOfA… loads github://zweidenker/Units/src (which is master). I found a solution for this: In the preLoadDoIt of my baseline I lock Units to a certain commit. preLoadDoIt Metacello new baseline: 'Units'; repository: 'github://zweidenker/Units:98d5a3d/src'; lock. This solves my problem in this example. Disadvantage is that I have to analyze everything which is loaded from the projects I use and create a lock for it. Questions: 1.) Wouldn't it make sense to have some mechanism, perhaps in Rowan then, where I can say that a project which has a number can only reference other projects with numbers? This would avoid the whole problem 2.) How do others solve this problem? addendum: I do not speak about project versions which are in development, here #stable or master are great features. But sometime when a project has a certain state, and it gets a version, then it should not change..imho -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi Serge, Albrecht, loading OSProcess directly with the following expression works: Metacello new configuration: 'OSProcess'; repository: 'http://www.squeaksource.com/MetacelloRepository'; load There is still some work to be done on OSProcess adaptation to Pharo 7, but they are in rarely used parts.

Hello, Not many people are using it, but it should be not much problem make it run in Pharo 7 (and with current version of Seaside).

Hi Albrecht, I am sorry that I cannot check it right now, but it may be that ConfigurationOfOSProcess needs to be updated. The #ifNotNilDo: problem was fixed by Thierry Goubier in July 2017, so perhaps you are using an out of date version. Hopefully someone else can give you a better answer, otherwise I will try to follow up in a day or two.

Pier3 & content management
by Albrecht Baur Feb. 19, 2019

Feb. 19, 2019

Hey, what is the status of Pier3 + Pier3AddOns ? -> Seems to me that it is discontinued since Pharo 5, right ? I'm asking because I look around to see if there is a project usable as a starting point of a small web content management module for seaside (nothing too complicated / fancy). Is there something besides Pier that goes into this direction ? Thanks for hints, Albrecht

OSProcess / OSSubprocess / LibC uniqueInstance
by Albrecht Baur Feb. 19, 2019

Feb. 19, 2019

I need to execute OS commands from within a x64 pharo 7.01 image on centos7 (for example: 'zip -r 123.zip zipme/'). I found these 3 tools: OSProcess, OSSubprocess, LibC uniqueInstance But I did not find any docu on which one to use for which use case. * OSProcess is in the catalog browser but fails loading because of ByteArray>>ifNotNilDo: -> So OSProcess is not to be used with p7 ? * OSSubprocess loads via catalog browser and the following snippet works (even though 64 bit): OSSUnixSubprocess new Â Â Â command: 'zip'; Â Â Â arguments: #('-r' '123.zip' 'zipme'); Â Â Â redirectStdout; Â Â Â runAndWaitOnExitDo: [ :process :outStringÂ | Â Â Â Â Â Â outString inspect Â Â Â ] So is it ok to use OSSubprocess with 64 bit even though documented as 32 bit only ? (here: https://github.com/pharo-contributions/OSSubprocess#installation) * LibC uniqueInstance system: 'zip -r 123.zip zipme/' ... works, but I don't know if its the right tool for this. Is there somewhere more info on which tool to use for which use case ? Thanks in advance! Albrecht PS.: I need to use zip as os process only because of this issue: https://github.com/pharo-project/pharo/issues/2584

Pharo 7: Problems with the new file chooser UI
by Offray Vladimir Luna CÃ¡rdenas Feb. 19, 2019

Feb. 19, 2019

Hi, While I'm migrating Grafoscopio to Pharo 7 I get a deprecation warning telling me that I need to change the previous code for choosing a file from the UI, but now when I proceed as advised (using |chooseExistingFileReference: title extensions: exts path: path|). It returns a |FileReference| but all the paths are referred to the place where the running image is located, instead of the place where the selected file is located. For example if you run: [1]~~~~ (FileLocator documents / 'test.ston') ensureCreateFileÂ writeStreamDo:Â [:stream | STON put: (Rectangle center: 10@10 extent: 100@50) onStream: stream ]. ~~~~ You will get a file on your Documents folder called test.ston, but If I choose that file using: [2]~~~~ file := UIManager default Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â chooseExistingFileReference:'Choose a file' Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â extensions: #('ston') Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â path: FileLocator documents. ~~~~ and I choose the "test.ston" file created at [1], Pharo tells me that the file is located in the same place as the running image, instead on my Documents folder. Am I missing something? Thanks, Offray
