Playground inspector and the self variable
by Esteban A. Maringolo May 30, 2015

May 30, 2015

Is it okay that the Playground's inspector drills down on the self variable indefinitely? It is... #(1 2 3) "Do it and go" will result in an Array being inspected, if I click on "self" it will open a new inspector on the side on the same object, and this can as deep as you want. I would block that from happening, in the raw tab, the "self" variable shouldn't drill down, sometimes I just want to select it to run an expression where self refers to the inspected object. Does it make sense what I propose? Or is there any use case where drilling down recursively ad infinutum is useful? Regards! Esteban A. Maringolo

Is it always needed to redefine #hash message when you redefine #= message?
by Julien Delplanque May 29, 2015

May 29, 2015

The subject of this mail is exactly my question. I came to this question by looking at Object>>#= message implementation. """ = anObject "Answer whether the receiver and the argument represent the same object. If = is redefined in any subclass, consider also redefining the message hash." ^self == anObject """ When do we need to redefine #hash message? Is it the right way to implement equality between two objects or is there another message that I should override? Regards, Julien

Diffing Monticello package against image contents
by Esteban A. Maringolo May 28, 2015

May 28, 2015

Is there a way to compare the contents of a Monticello package (mcz) against the contents of the image *REGARDLESS* of the packaging? It is... I want to compare methods and class definitions from a mcz, that has a monolithic package (PostgresV3 in this case) against what I have loaded in the image, which has different packages (PostgresV3-Core, etc.). As it is today, if I select PostgresV3.mcz and select the "Changes" menu, it will mark everything as changed, because such package doesn't exist in the image. If PackageA contains a method ClassX>>#methodA, I want the contents of such method to be compared to what I have in the image, no matter if ClassX>>#methodA belongs to PackageB or PackageC. Does such feature exist? Something like a chunks browser, but using a Monticello package instead of a chunk file. Esteban A. Maringolo

PunQLite jx9 Documentation
by Gareth Cox May 28, 2015

May 28, 2015

Hi All I'm using PunQLite for a prototype I'm developing. I'd like to find out more about how to do the jx9 stuff with PunQLite. I see there are examples to run simple jx9 code, but I was hoping to find something more detailed, like how to query, filter, or work with the database using jx9.

Idea: Pharo application scaffold kickstarter
by Andreas Brodbeck May 28, 2015

May 28, 2015

Hi all I get used to Pharo more and more, and I am using it for all my new customer projects. So far, all of my (seaside) applications are all architectured around some of my best practices and architecturally look all pretty the same. I was wondering if there is something existing to help me getting kickstarted with a new customer application in Pharo, instead of repeatingly copy/pasting manually from another project? Something for kickstarting a new application scaffold, based on a "best practices application template" (to be chosen out of many from a repository locally or even remotely shared from other developers). Something like a "Pharo application scaffold kickstarter". I did some research and did not find anything so far. What are your thoughts around this topic? Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch

Hi, I want to read a file that is created by an external process. I need to read this file after the external process is finished. I have an instance of FileReference to this file. Is it possible to know if the file is being written or it is closed? thanks. SebastiÃ¡n
