Error creating textual references to dropped morphs
by yakovdk 08 Sep '16

08 Sep '16

I am a Smalltalk newb, so please forgive me if this isn't the right place to go with this. I was following a guide that had me open a workspace, set "Create textual references to dropped morphs", and then drag in a morph from the Workspace. It worked great for me on one machine, which had an older version of Squeak. But on my Mac, I just installed Squeak 5.1 and when I tried this, I got an error about 'nil' not responding to the "isOctetString" message. As I said, I'm a baby smalltalker, but I looked at the older versions of the "acceptDroppingMorph" method on the Workspace class. I found that if I changed the section that reads as follows: (dropee isKindOf: TransferMorph) ifTrue: [reference := dropee passenger. externalName := dropee passenger className] ifFalse: [reference := dropee. dropee externalName]. It looked to me like the "ifFalse" branch fails to set the externalName variable, which makes it nil later on. I changed it to read as follows, and it seems to work fine for me now: (dropee isKindOf: TransferMorph) ifTrue: [reference := dropee passenger. externalName := dropee passenger className] ifFalse: [reference := dropee. externalName := dropee externalName]. As I said, I'm new to the Squeak world, so I'm not sure where or how to send this in to the right place, so please correct me if I should be sending this somewhere else. Thanks!

Method strings containing it
by Chris Muller 08 Sep '16

08 Sep '16

Pressing Shift+Cmd+E is "Method strings containing it". It opens a Method browser, used to be only on the methods with String literals which contained the selected string. Now, however, it is returning methods whose source code text contains that string anywhere, which is almost never what I want, plus there was already a capability to search method source code for a string. Did something get broke here?

What is the Squeak VM binaries location and configuration?
by Chris Muller 07 Sep '16

07 Sep '16

Hi all, one of my workmates (who is a Smalltalk veteran) just asked me how to run a Spur image I had given him. That this question needs to be asked by someone like him should tell us something about our current VM accessibility, but the fact I was unable to give him a straight answer, even moreso. Shouldn't it be obvious enough even for newbies, but there are so many plausible answers to this question which are simply incorrect: - squeakvm.org is only for old interpreter VM; totally misleading to a newbie. - It *does* have a reference to the "Unofficial and experimental "Cog" virtual machines" which leads new users to: http://www.mirandabanda.org/files/Cog/VM/ whereupon we have "lattest" and "stable". Great! - Not great, because those are actually old too. So squeakvm.org is just a wild-goose chase, ha ha sorry newbie.. :( - Sigh, okay, so what about squeak.org --> Downloads? Surely there's a recent VM there? Well, selecting the Linux (x86) link lets me download Squeak5.1-16548-32bit-201608171728-Linux.zip. However, this file organizes the VM in a totally non-standard way (everything under /bin, no /lib directory), so I didn't want to point him to that one, because we have existing scripts which assume the legacy organization and I don't want to wrestle with installation / configuration issues. - SO, I was about to let him him in on the github whipper-snapper secret that only a few, In-The-Know Squeak Elites know about, myself, learned only a couple of days ago! https://bintray.com/opensmalltalk/vm/cog/#files but its this massive jumbled list of a hundred or more tar files. I can sort them by name, and *I* can find the right VM tarball for myself, but how to tell someone else? Searching that web page for "linux32x86_squeak.cog.spur" will find just 12, from which I can select one of the many generated all in the same day? So is there still a "stable" version? Whew! So, 1) what is the best answer for my workmate, and 2) how can we make this easier? Thanks.

Fwd: [aida] 20 Years of Aida/Web
by H. Hirzel 06 Sep '16

06 Sep '16

FYI, another piece of software for Squeak -- ported 2007 to Squeak. I don't know about the current support in Squeak 5.1 --Hannes ---------- Forwarded message ---------- From: Janko Mivšek <janko.mivsek(a)eranova.si> Date: Tue, 6 Sep 2016 20:40:22 +0200 Subject: [aida] 20 Years of Aida/Web To: Aida/Web general discussion list <aida(a)aidaweb.si> Hi everybody, It happens that Squeak and Aida were actually born on the same year. Namely, at summer 1996 the Aida development started and late in this year a first Aida project was already online: a bookstore for a major Slovenian publisher. The next most important milestones: - 1998: a Gas Billing System was developed as a pure web application with Aida, heading Aida primarily into business web app domain; - 2000 Aida becomes Open Sourced and introduced more broadly at first Camp Smalltalk in San Diego; - 2006: Ajax support, just few months after Ajax was coined, Aida already had a fully integrated and seamless Ajax; - 2007: Squeak port, a website, mailing list, community building - 2009: Aida logo and new website design - 2011: Realtime with WebSockets, HTML5, mobile Even that it is currently quiet in the community, Aida is evolving and consolidating all HTML5 and realtime achievements in 'HTML5 rush years', running daily internal web portals in companies, like for ISO9000 Quality Management doc systems, Gas Pipeline Measure Management etc. It certainly proved that its architecture is sound enough to stand the test of a time for past 20 years, so it certainly will for many more years to come.

Squeak 5.1 Windows doesn't show image name at the Top
by Herbert König 06 Sep '16

06 Sep '16

Hi, other than on RasPi the Windows version 5.1 does not show the image name in the title bar of the application window. Right now I have 6 images busy and on my Windows machine it's hard to know which is which. Oh and I noticed we changed from the Squeak mouse to the Smalltalk balloon Icon. Well I'd prefer the special Squek symbol over the general Smalltalk symbol. Cheers, Herbert

order of ensure: processing vs. error handling
by Chris Muller 06 Sep '16

06 Sep '16

Hi all, I have some in this code in which I try to read a file and, if it fails, try to read it in a different way. But the order of processing ensure: blocks vs. error-handler blocks is not what I expected. I expected the ensure: block of the inner handler to run before the outer handler. Here's a simple workspace to demonstrate. The temp var "open" represents the status of a FileStream. |open| open:=nil. World findATranscript: nil Transcript clear. [ [ [ "try method1" open:=true. Error signal] ensure: [ open:=false] ] on: Error do: [ : innerErr | "try method2, but file still open!" Transcript cr; show: 'innerErr handler, open is ', open asString. innerErr return: ([ open:=true. Error signal ] ensure: [ open:=false ]) ] ] on: Error do: [ : outerErr | Transcript cr; show: 'outerErr handler, open is ', open asString ]. Transcript cr; show: 'Done. open is ', open asString. It seems none of the ensure blocks are processed until after ALL the error-handler blocks. So if a #fileNamed:do: deep deep in the stack encounters an Error, the file is still open in the upper-level handlers, with no good way to close it..
