How do I browser references to a class listed in a method?
by TimM Aug. 16, 2010

Aug. 16, 2010

This has been driving me crazy. If I am looking at the following method in a browser: renderContext "Answer a fake rendering context for this pusher." ^ WARenderContext new document: (WAHtmlDocument on: (WriteStream on: String new)); actionUrl: WAUrl new; yourself How do I - if I hilite WARenderContext: 1) Browse other methods that reference the class? There is a context menu item "methods containing (E)" - this just gives a walkback error (doesNotUnderstand: #allMethodNoDoitsSelect). I am used to having, senders, implementors and references (is that menu item the equivalent of references but its just broken?). 2) Browser the hierarchy of the selected class (not just the class)? In both cases - it seems like I have to do a Cmd-B (browse class) and then from that window I can then do the operations I am after. But this gives me an extra window floating around (I think I am starting to understand why Squeakers complain about window orphans, and killing of windows). Is there some shortcut I am missing? Tim

is there an unique URL to the latest pharo core or dev release?
by Bernardo Ezequiel Contreras Aug. 15, 2010

Aug. 15, 2010

Hi All, is there a unique URL to the latest pharo core or dev release? For example(it just an example to express my idea, it could be different), if i want the latest Pharo Core release, i would like to access the following URL www.pharo-project.org/PharoCore/latestRelease/ | -> a Zip file with the latest release The same applies to Pharo Dev, it could be www.pharo-project.org/Pharo/latestRelease/ | -> a Zip file with the latest release Therefore, i could write a script to download the latest release when you announce a new one. The truth is that i am too lazy to access the web browser and navigate to the download page. Perhaps, i am missing something here. Could you help me? thanks in advance

SqueakCompatibility
by Sean P. DeNigris Aug. 15, 2010

What is SqueakCompatibility? It's listed as a non-core package on http://book.pharo-project.org/book/table-of-contents/PharoTools, and the only reference I found in the mailing lists was a slice for Menu Registries. Is this one the same? The name sounds like it may be intended as a more general compatibility layer. Thanks.

Getting started

Hi, Trying to follow the example in the book, but the first thing to do is to create a new package. The browser in 1.1 doesn't have that option and there's no sign of the O2PackageBrowserAdaptor in the menu. using ScriptLoader loadOB from the online FAQ just gives an error. Any advice? TW

Maybe this can be cleaner using the >bindings.. It does'nt seem to work on Pharo 1.2 but i fixed it with Announcement ^^ I've also improved the example. I'm still working on the code, I'll push a version this evening I think Ben

The list is empty when you just have initialize the RecentMessageList (ie the first time you launch it) but you can reset the list by sending : RecentMessageList resetUniqueInstance Otherwise it's never automatically cleaned (but you can remove each node you want) I know the recent messages by registering the class in the SystemChangeNotifier, and they are stored in the RecentMessageList uniqueInstance messageList > > > Thank you very much and continue with the good work!
