[Pharo-project] doing bad things to Dictionaries.

by David Goehrig

So I've been doing some very bad things to dictionaries, and I've had to make a small change: 'From Pharo0.1 of 16 May 2008 [Latest update: #10342] on 8 July 2009 at 12:28:04 pm'! !Dictionary methodsFor: 'testing' stamp: 'djg 7/8/2009 11:53'! hasBindingThatBeginsWith: aString "Answer true if the receiver has a key that begins with aString, false otherwise" self keysDo:[:each | each ifNotNil: [ (each beginsWith: aString) ifTrue:[^true]]]. ^false! ! I'm occasionally had code blow up and was left with nil keys in my SystemDictionary (which may be a red herring), and SHParserST80 resolvePartial: was throwing fits as a result of what I believe was an environment key being nil. I doubt this is a suitable fix, but if someone know why that might happen I'd love to hear it. Dave -- -=-=-=-=-=-=-=-=-=-=- http://blog.dloh.org/

This is strange because it is interpreted as if it were a DropFilesEvent! But this is just a alt + tab. I don't see the relation between and alt + tab and a DropFilesEvent Mariano On Wed, Jul 8, 2009 at 2:47 PM, Mariano Martinez Peck <marianopeck(a)gmail.com > wrote: > > > On Wed, Jul 8, 2009 at 2:15 PM, Torsten Bergmann <astares(a)gmx.de> wrote: > >> Hi Mariano, >> >> I dont have this problem.

[Pharo-project] Annoying bug: UndefinedObject(Object)>>doesNotUnderstand: #mimeTypes

by Torsten Bergmann

Hi Mariano, I dont have this problem. But I think I had this problem with an old VM. Can you try the new Win32 setup that is based on 10371: see http://lists.gforge.inria.fr/pipermail/pharo-project/2009-July/010469.html to make sure you have the correct VM and image? Which Win version do you use? Thanks Torsten -- Neu: GMX Doppel-FLAT mit Internet-Flatrate + Telefon-Flatrate fÃ¼r nur 19,99 Euro/mtl.!* http://portal.gmx.net/de/go/dsl02

Re: [Pharo-project] extended search -> senders of it (n) - defect?

by Cameron Sanders

Thank you, that is informative! So, if a guy, a semi-newbie at that, were to want to write his own search method to look for particular byte-code patterns (suggestive of an inlined ifNil:) ... what would be some useful examples or a good place to start learning? MethodFinder, or is there a better example? And, on a related note, if I more generally wanted to write a module to eject/translate-to Objective-C instead of C, where would be a good place to get started on that learning curve? (Are the classes that *once* ejected C code for the VM still functional? Are they in Pharo?)

[Pharo-project] Annoying bug: UndefinedObject(Object)>>doesNotUnderstand: #mimeTypes

by Mariano Martinez Peck

This bug is really annoying. I am in windows, using 10371. Both: Pharo and PharoCore, have the same problem. To reproduce: 1) Go to squeak 2) alt + tab to switch to another windows 3) alt + tab again to come back to squeak At that moment, we you get the focus in Squeak you will get TWO DNU. They are the same. I attach SqueakDebug.log Please consider this for 1.0 because it is unusable. I created the ticket: http://code.google.com/p/pharo/issues/detail?id=945 Cheers, Mariano
