Re: [Pharo-users] Nautilus SBD IC buttons

i had opined the same at the very first cut. the one unaesthetic element of the browser, which puts me off from using the browser itself... these are the source, bytecode, decompiled ... ecquivalent of much nicer simple, drop down of the yore.

I started to flag some issues wth springChile.

I never use them because I never remember what they mean and because there are ugly :) I should say that the idea to show if we can class methods is just great.

I do not think that you need ston. You plain smalltalk code is good enough to trigger the correct metacello file. metacello is key for the projects dependency management and complex projects. Once we will have the continuous validation of pckage ready + binary loader we will get ready for a new phase in Pharo. Stef

good :) maybe I have time to do a pass on the tracker...

Nautilus SBD IC buttons

by Francois Stephany

Am I the only to never use the buttons on the right in Nautilus? In practice, when do you need to see the bytecode/decompiled versions of a method? Is there a way to trigger the Instance and class variables buttons with a keyboard shortcut? Is there a way to remove completely the panel containing those buttons? Cheers, Fa

I would like to suggest that anyone who is interested joins, and we can produce a first attempt at a plan - and maybe some running code :-). Anyone else interested?

<<< I would prefer to upload a MetacelloConfiguration (or something similar) instead of an image. I like to think about the image as a temporary runtime. Not something where I store code or someting I deploy. I would love to have something like: $ pharo -v 1.4-summer myProject.ston where myProject.ston would contain all the necessary information to load my project (dependencies, repositories, etc). This command would create an image with my project on the fly from a stock Pharo 1.4-summer and launch it. It would recreate the image everytime I want to work on my project (or when it is deployed). The problem right now is the loading time for dependencies (try to load seaside in a pristine image, you'll get the point). All the other bricks are there.>>> Sounds like a very good idea. Does anything like that exist already? Also, it raises the question of what should be in the base image. Cheers Andy

Re: [Pharo-users] How do i list the execution order of statements inside a method?

by Jesus NuÃ±ez

About your *pending question*, you should read the very basics of smalltalk before trying to understand its abstrations. Just to give you a hint (I will use the Point example): (Point>>#x) "==> (Point>>#x "a CompiledMethod(880017408)")" #aSymbol is just a singletone version of the string "aSymbol"; In what to classes concerns it is used as a unique identifier in the method dictionary. The rest is just syntax ">>" is the selector(s) (method(s)) accessor, it will retrieve the keyed selector (in this case #x which again is unique in the class) value, which is a CompiledMethod(atSomeAddress). Now you can also get the contents as a string if you want to parse it yourself (compare to (Point>>#x) parseTree ): (Point>>#x) definition "==> 'x "Answer the x coordinate." ^x'" Which is nothing more than the contents of the selector #x. I suggest, if you want to get a "personalized" version of the parse tree, to try PetitParser, there are many examples and even a Smalltalk80 parser in there.
