[ANN] Basic GitHub-API for Pharo
by Torsten Bergmann Sept. 23, 2016

Sept. 23, 2016

Hi, to get warm with Git, GitFileTree and Iceberg last week I was in need of something quick I could implement to try these new tools out. While being on my GitHub webpage I've seen at the bottom a link to "API" and was happily surprised that GitHub could be accessed also with a REST API. So I wrapped a few of these calls within Pharo and now you can also query GitHub infos easily from inside of the image: (GitHub userNamed: 'astares') avatar inspect "Returns the avatar form" (GitHub userNamed: 'pharo-project') isOrganization (GitHubUser named: 'pharo-project') repositories Code could be improved and extended further, possible also be used for accessing/controlling GitHub from Iceberg later. If you want to play with it just load it from Catalog in Pharo 6.0. Code and docu is available on https://github.com/astares/GitHub-API Have fun T.

Spec: Class pop list code completion
by Brad Selfridge Sept. 23, 2016

Sept. 23, 2016

Is there a way in Spec to pop a list widget that contains class names when entering a partial class name in a test field, (like GTPlayground does)? p.s. I do not want to go down the Glamour route. ----- Brad Selfridge -- View this message in context: http://forum.world.st/Spec-Class-pop-list-code-completion-tp4916672.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Strange behavior with software update
by Norbert Hartl Sept. 23, 2016

Sept. 23, 2016

My project I load via filetree so for every package I have a filetree repo assigned. I have a code snippet that changes all the filetree repos to gitfiletree ones. But when I do System->Software update the repositories are back to the filetree ones. Anyone has an idea what could cause this? thanks, Norbert

Using a Unix filedescriptor in a FileStream?
by Holger Freyther Sept. 23, 2016

Sept. 23, 2016

Hi, I explored to use the Linux inotify API using UFFI. The inotify_init/inotify_init1 routine will me a Unix filedescriptor and I would like to a.) monitor it for being readable b.) read from it with a stream For a.) I have found the AioEventHandler and think I will be able to call >>#descriptor: directly and then can use it (still figuring out the API, probably just wait for the >>#changed: call). For b.) I thought I could use AttachableFileStream but that required a "fileId" but not a filedescriptor. Is there a way I can read from my fd using the standard stream API (otherwise I can try to use UFFI for read) regards holger

Hello, i just updated to macOS Sierra, and Pharo now starts with an empty black window and 100% CPU load and stays like this forever. Any ideas? Best regards, Martin. -- View this message in context: http://forum.world.st/Pharo-not-running-with-macOS-Sierra-tp4916468.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

strange cache behaviour for DSAdaptiveModel magritte description
by Yanni Chiu Sept. 22, 2016

Sept. 22, 2016

Does any one have any insight into the caching of magritte descriptions for DSAdaptiveModel? What I see is that there seem to be multiple copies of the description elements. A problem appears when a MACachedMemento seems to have a different description instance (a different hash value anyway), but the rest of the values seem to be the same as the other copy.

Sharing Seaside URLs between users (security) + what is actual way for session expiration page
by Petr Fischer Sept. 22, 2016

Sept. 22, 2016

Hello, two questions about Seaside sessions: 1) URL sharing between different users - what if "boss" shares URL from his browser and send it to another regular user - of course, easy way, whole URL with session (_s=xxxx) - when another/regular user opens that link -> whole "boss" session opens in regular user's browser, with all "boss" permissions, UI state etc etc - very bad, is there any solution for this? Rewrite every (!) URL with updateURL: is not solution :( 2) What is the actual way for "session expiration/login page"? There is few tutorials and books on the inet - but info about session expiration is obsolete :( Methods from tutorials not exists in Seaside 3.2.0. Some trick with WAApplication subclass is actual? Thanks very much! pf

Pharo 3.0 Issue with instance variables
by Pablo Frias Sept. 22, 2016

Sept. 22, 2016

Hi all, We are teaching Smalltalk at the Universtity of Cordoba, Argentina with Pharo, but we are having the following issue. Sometimes y in different workstations, we notice that when instantiating an object and setting values using the accesors methods, the values are added in the object, but in different instance variables. For example: |a| a := MyPersonObject new. a age: 35. a name: 'Person name'. But when using the object, we notice that 35 has been saved to name and the string to age. Is that a known issue? Unfortunately we haven't tested Pharo 5.0 yet, so I cannot tell you if it is already fixed. Our current image is: Pharo 3.0 on Windows. Thanks in advance, Pablo

Non-Pharo IDE in Pharo
by Udo Schneider Sept. 22, 2016

Sept. 22, 2016

All, I'm currently working on an interpreter for a non-Smalltalk(ish) language in written Pharo. I'd like to put some nice tools on top of that (like browsers, inspectors, debugger) but I'm not sure where to begin. Is there some "Meta-IDE" stuff somewhere which allows me to simply plugin into or is it reinventing the wheel? CU, Udo
