Re: [Pharo-users] NativeBoost and standard out

by Emilio Oca

Hi Esteban > I recommend you to take a look at this:Â > http://smalltalkhub.com/#!/~OS/OS-Windows > there can be a solution (not sure, because I never used it) Yes I did, I got something like this si := WinStartupInfo new. si wShowWindow: 0. pi := WinProcessInformation new. WinProcess createProcess: aCommand startupInfo: si processInformation: pi. [ (WinProcess waitForSingleObject: pi hProcess timeout: 10) > 0 ] whileTrue: [ (Delay forMilliseconds: 10) wait. ]. pi hProcess closeHandle. pi hThread closeHandle. That gives me some synchronicity betwtenn several of these proceses without freezing the image aCommand may be... 'sqlplus -S usr/pass@QA @V:\work\suite.sql > proc.log' works but doesn't writes into proc.log 'c:\path\test.bat > proc.log' works as expected I am looking for a way to get at least the sql sentence stdout writen into a file. > Other possibility is not using NB but OSProcess:Â > http://www.squeaksource.com/OSProcess.html > hope it solves your problem.Â I am exploring this now, thanks > cheers,Â > Esteban Best Emilio -- Best regards, Igor Stasenko.

Removing an obsolete class

I found I have to obsolete classes, but I can't remove them from the system. GptDatedModel subclass: 'AnObsoleteAnObsoleteGptRouteItemRegistration' instanceVariableNames: 'routeItem' classVariableNames: '' poolDictionaries: '' category: 'nil' They show in the "_UnpackagedPackage" UndefinedObject(Object)>>doesNotUnderstand: #isByteString ByteSymbol(String)>>compare:with:collated: ByteSymbol(String)>>compare:caseSensitive: ByteSymbol(String)>>sameAs: RPackageOrganizer>>packageNamed:ifAbsent: in Block: [:each | each sameAs: aSymbol] Array(Collection)>>detect:ifNone: in Block: [:each | ...

a BitSet class

by Torsten Bergmann

Hi Pablo, can you be more specific why you need a BitSet class other than convinience? What do you want to do? Note that for bit handling in Smalltalk you can easily just send messages to integers or large integers: Access bits: 12 bitAt: 1 -> 0 Modify bits: 12 bitAt: 1 put: 1 -> 13 Print binary: 12 printStringBase: 2 -> '1100' Print hex: 12 printStringBase: 16 -> 'C' Large number: 67677557657 printStringBase: 2 -> '111111000001111001011001001110011001' There are also #bitAnd:, #bitOr:, #bitXor: messages: 12 bitOr: 1 -> 13 12 bitAnd: 8 -> 8 and you can use the abbreviations known from C world: 12 | 1 -> 13 12 & 1 -> 0 If you want to see the bit representation just print as a string with base 2: 12 | 2 printStringBase: 2 -> '1110' So for octal use: 12 | 2 printStringBase: 8 -> '16' If you disklike to stay in decimal system you should be aware that in Smalltalk you can easily write a number in different bases directly using the "BASE, followed by r followed by number" representation. So you can for example write: 12 as 2r1100 as 16rC as 10r12 (decimal again) as 8r14 (octal) or any other base that you like directly With this you can also easily manipulate bits while writing in bit representation: 2r0001 bitOr: 2r0101 -> 5 same as: 2r0001 | 2r0101 -> 5 when you need the result again as bits: (2r0001 | 2r0101) printStringBase: 2 -> '101' Many other convinience methods are there like: 12 hex -> '16rC' 12 printStringHex -> 'C' $A hex -> '16r41' $A printStringHex -> '41' Feel free to mix all that (16rFF00 | 2r00001) hex -> '16rFF01' Try to get used to these methods and you will have fun with bits in Pharo Smalltalk easily. If you need something more tell us, a BitSet class implementation could be easily written using the above as a base. Bye T.

a BitSet class

by Pablo Herrero

Does anyone knows about BitSet class implementation lying around on the image or some external project? Thanks in advance.

Tkanks Ben for your corrections and your encouragement, Google help me a little :) but it's a good exercice, especially if i want to make me understand in the Smalltalk community.

Hi Stef, It would be a pleasure but i'm located in Brest, so,a bit too distant... For holidays maybe ? :) But you can come in Brest if you want ? it's so beautiful !
