by Ben Coman June 25, 2012

June 25, 2012

I didn't see any response to my previous report of this a few days ago... so is it just me? Does anyone else have Firefox 12.0 on Windows 7 ? and can you confirm http://www.pharo-project.org looks fine for you ?

[Pharo-project] Where is the PBE VM?
by Malcolm Macgregor June 25, 2012

June 25, 2012

At http://www.pharo-project.org/home under "Get started now" is the link "Get the Pharo By Example book..." On downloading, the zip file does not contain the VM. Also, P1.4 VM (Windows) does not work with the PBE image. -- View this message in context: http://forum.world.st/Where-is-the-PBE-VM-tp4635676.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

I would remove it, it's a reminisce of Sophie surely. They used to have Pango and Cairo bindings.

[Pharo-project] FIleSystemStreams
by Sven Van Caekenberghe June 25, 2012

June 25, 2012

All in all the switch to FileSystem is very good. File/Directory manipulation is much improved. (But it does create a problem for library/framework writers, like me, that want to remain compatible with 1.3 and 1.4) However, when trying to actually use FileSystem and when looking at the current users in the image, I see a problem (coming up) with FIleSystemStreams and its subclasses. They should be binary, but they are silently used as character based, either relying on implicit conversions or explicit ones, without proper encoding. This is wrong. Why is there a FileSystemReadStream>>#nextLine ? Why is there no FileSystemReadStream>>#next:into:startingAt: the cornerstone of efficient input ? Why are there FileSystemWriteStream>>#[tab|space|cr|crlf|lf â¦] methods on a binary stream ? Because even with these methods that should not be there, the streams opened by FileSystem cannot be used for simple parsers or renderers, simply because the elementary #next and #nexPut: deal with bytes instead of characters. Some time ago, I did a quick experiment by adding ZnCharacterReadStream and ZnCharacterWriteStream to Zn (in a later version than what is in 2.0, I include a file out) that solve this problem from my perspective (but they don't allow arbitrary #position[:] hacks). Another question is how buffering works (if present at all), since it seems to be hidden in the plugin ? What do the FileSystem hackers, Cami, Sean, et al, think about this situation ? Sven

[Pharo-project] Debugging code with morphic leads to freezes and a weird message
by phil＠highoctane.be June 25, 2012

June 25, 2012

While debugging actions behind buttons, I do get Project class>>spawnNewProcessIfThisIsUI: not being understood. This prevents from debugging interactions properly. And sometimes I get the dreaded "Computation Terminated" message, effectively locking me out of the image (nothing moves anymore, I've got to kill the process). Ideas on how to fix? This is 1.4 14438 -- Philippe Back

[Pharo-project] fulltext method search
by Camillo Bruni June 25, 2012

June 25, 2012

I was bored today (after yet another kernel panic) so I implemented a quick fulltext search for methods. "this takes around 1.5mins" Search default buildIndex. "this is an instantaneous (~2ms!) search over all method sources" Search default matchSentence: 'Convert to a String with Characters' I think we should integrate that into some kind of "SpotLight" search for accessing the sources much much faster... The current draft is available here: http://smalltalkhub.com/#!/~dh83/spotlight

[Pharo-project] Strangest object ever seen?
by Pavel Krivanek June 25, 2012

June 25, 2012

Hi, If you take the latest Pharo 2.0 image from Jenkins (20059) and you execute the expression: (Metaclass allInstances select: [:c | c superclass = ProtoObject class]) inspect you will get an collection inspector where the first object is very strange one. It is very hard to get any useful information about the origin of this evil object. The only thing we know exactly is that it causes virtual machine segmentation faults while trying to export class ScrollBar via Fuel. Not only CogVM but even StackVM. Can you, please, try to help us to get as much information as possible about this object? I named it "dzindzik" :-) Cheers, -- Pavel
