[Pharo-project] About moving tmp closer their use
by StÃ©phane Ducasse Jan. 4, 2010

Jan. 4, 2010

Hi guys in squeak a week ago nicolas pushed a cool (from my taste) changes that refactored the complete system so that |temp| declaration would be at the scope where they are used. This is not clear that this is an optimisation but I like the fact that temp are defined at the right place. Now it may lead to code that is a bit less readable in the sense that your temps are not systematically listed at the beginning of the method but occasionally in the closures that use them. >From my hackish lisping state of mind I like it now what do you prefer?

Hi Andreas, > This may be the stupid question of the day, but can someone explain to me why we aren't just hard-wiring the word size (say in a CompiledMethod class var or so)? It's not like the primitive would *ever* return anything else unless you grind the image through SystemTracer, the value of wordSize is initialized only one time, If wordSize is nil, it takes the value of the primitive 40. > and if you do that, SystemTracer can simply update those values. Yes, it does. SystemTracer pushes the value of primitive 40 in wordSize. > It seems silly to build caches, primitives, cache invalidation for a value which will never ever change dynamically. Besides I think the cache invalidation might be wrong - The "cache" is synchronized with the VM only one time after the creation of the image, I think it is better than a hard-writing value. > how do you know that initialPC or other word size related methods aren't sent before the startUp method is executed? startUp method is the first method executed at the startup, no ? But in SystemTracer, the value is initialized in "clonePreStartup" method. So there is no problem with potential method calls before startUp. > > Cheers, > - Andreas Cheers, --- Jannik Laval ---

[Pharo-project] Can't use <Enter> key to select notifier action
by danklein Jan. 4, 2010

Jan. 4, 2010

When a notifier pops up, you can tab (or shift-tab) to the Proceed/Abandon/Debug/Create buttons at the top of the window. However, when the one you want is highlighted, I would like to be able to just press the to execute it, but you have to actually click on it. Is there a configuration setting to affect this behavior? -- View this message in context: http://n2.nabble.com/Can-t-use-Enter-key-to-select-notifier-action-tp419464… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Does someone know why Nile is in Dev images?
by Mariano Martinez Peck Jan. 4, 2010

Jan. 4, 2010

Does another package of the dev image depends on Nile? If not, I don't understand why it is part of the dev image. I see it as any other external package but not a "dev tool" that should be included. Thanks Mariano

Hi, I made a new version of the system-tracer (in attachment). It works fine with the latest pharo version. For wordSize, we decide to create a instance variable in SmalltalkImage, which is initialized at startup. The method initialPC is: --- initialPC "Answer the program counter for the receiver's first bytecode." ^ (self numLiterals + 1) * SmalltalkImage current wordSize + 1 --- The fix will be integrated in Pharo soon. It is also in attachment.

[Pharo-project] about and:and: and and:
by StÃ©phane Ducasse Jan. 4, 2010

Jan. 4, 2010

hi nicolas I saw that you apply some automatic refactoring in squeak about and:and: -> and: and I wanted to know. Is and: more optimized than and:and: (I imagine that) but I would like to know for sure. Stef

[Pharo-project] Code Critics pragmas for classes - do they need to be on instance *and* class side?
by Stan Shepherd Jan. 4, 2010

Jan. 4, 2010

Hi, this one's for Lukas. Where you set Code critics to pragmas- http://n4.nabble.com/Slime-in-one-click-image-tt100493.html#a100498 http://n4.nabble.com/Slime-in-one-click-image-tt100493.html#a100498 It seems only to work when the pragma is on both instance and class side. Is this the intention?
