To Camillo Bruni: I'm not using any slot image (I only looked over the paper). According to the Pharo book, 'pvt' should be implemented in the mainstream image. To Marcus Denker: There are actually several methods in the image with the 'pvt' prefix. Please update the doc (Pharo book) to remove talking about 'pvt'. It would have saved me a little headache :)

Run this and you will get an array with all PackageInfo (packages) instances: PackageInfo allPackages Cheers Christian On Thu, Apr 4, 2013 at 2:30 PM, ashwinshankar77 <ashwinshankar77(a)gmail.com>wrote: > Hi, > I'm a grad student at UIUC and I'm working on building > an automatic package(category) refactoring and visualization tool for > pharo. > As a first step,I need to figure out how I can programmatically get the > list > of packages/categories in the image. > To do this I tried the following - when I open the 'System Browser' > in pharo,the leftmost pane displays the packages.

Which Pharo version? This is probably not ideal but in Pharo1.4 you can right click on the categories and choose 'reorganize categories' If you use the 'Finder' to search the source code for the string 'reorganize categories' you end up in OBCmdReorgCats which is the class that runs the command which generates the category re-organization output. I didn't try to learn how but from there you ought to be able to find what you're looking for On 04/04/2013 10:30 AM, ashwinshankar77 wrote: > Hi, > I'm a grad student at UIUC and I'm working on building > an automatic package(category) refactoring and visualization tool for pharo. > As a first step,I need to figure out how I can programmatically get the list > of packages/categories in the image. > To do this I tried the following - when I open the 'System Browser' > in pharo,the leftmost pane displays the packages.

Need help with dynamically finding packages/categories on pharo

by ashwinshankar77

Hi, I'm a grad student at UIUC and I'm working on building an automatic package(category) refactoring and visualization tool for pharo. As a first step,I need to figure out how I can programmatically get the list of packages/categories in the image. To do this I tried the following - when I open the 'System Browser' in pharo,the leftmost pane displays the packages. So I did a bit of reverse engineering and started looking into the SystemBrowser class to see how it gets the list of packages.But I'm not able to figure out. Can you please let me know how I can get the current list of packages in the image(basically the packages as displayed in leftmost pane of System Browser) ? -- View this message in context: http://forum.world.st/Need-help-with-dynamically-finding-packages-categorie… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
