Change in NativeLinux32>>getGlobalSymbolPointer
by Jesus NuÃ±ez Jan. 12, 2013

Jan. 12, 2013

I have made a small change in the code because NBExternalAdress does not inherit from NBExternalStructure anymore. It is safe?. I mean so far no problems but my understanding is limited so I haven't make any commit. getGlobalSymbolPointer: symbolName | bytes addr | bytes := ByteArray new: 8. self bootstrapGetGlobalSymbolPointer: symbolName into: bytes. addr := bytes unsignedLongAt: 1 bigEndian: false. addr = 0 ifTrue: [self error: 'failed to get a symbol address: ' , symbolName]. +^ NBExternalAddress ulongAt: addr -^ NBExternalAddress value: addr Cheers

You could call ClassX addVariablesNamed: aCollection in this case Is ClassX an example of the MyUtils class Igor mentions? I tried that option using ClassDescription but got an MNU error.. e.g. right now I use the first option in this manner: | anyVariable | anyVariable := ClassType new. anyVariable addVarsAndTheirAccessors: #('aaaa' 'bbbb' 'cccc') How would I attach the method to a utilities class and ClassDescription for that matter as it would then apply to all classes? -- Frank Church ======================= http://devblog.brahmancreations.com

Is there a way to automatically format a method during the compilation phase or immediately after?
by Frank Church Jan. 12, 2013

Jan. 12, 2013

I followed the advice from this question on stackoverflow 14234003 and from there created this simple method to add instance variables and the basic accessors in one go. addVarsAndTheirAccessors: aCollection on: aClass aCollection do: [ :each | aClass addInstVarNamed: each; compile: each, ' ^ ', each classified: 'accessing'; compile: each,': aByteString ',each, ' := aByteString' classified:'accessing' ] Currently I have to click on the created methods and format them in the browser. Is there an option to format the method during the compile phase or an method that can be passed a collection of methods to format automatically? -- Frank Church ======================= http://devblog.brahmancreations.com

Rendering text to bitmap buffer then paintImage to a canvas
by Ben Coman Jan. 12, 2013

Jan. 12, 2013

I need to improve the performance of a lot of text that drawn on screen while the screen is being dragged around and would like to experiment with rendering the text to a bitmap buffer then painting that onto a canvas. How might that be achieved? And from Workspace can I test this? I have been searching for a couple of hours already so thought I'd just ask. cheers -ben

How can the main window title in Squeak and Pharo be set? In Pharo I thought it could be set in the System -> Settings Menu but couldn't find anything there. Can it be set only in code? -- Frank Church ======================= http://devblog.brahmancreations.com

Understanding ConfigurationBrowser
by Frank Church Jan. 9, 2013

Jan. 9, 2013

On using the ConfigurationBrowser I want to understand certain things. What is the difference between the packages in the Configurations and Untrusted columns. Are those in the Configurations column tested for the particular release and the converse for the Untrusted ones? I have compared the one for Pharo 2.0 vs 1.4 and the far fewer in the Configurations column with Pharo 2.0 -- Frank Church ======================= http://devblog.brahmancreations.com
