Hi Davide, That means you are looking at decompiled code, because the system can no longer access the source code. Source code lives either in the .sources or .changes file. Did you move or rename any of them ?

"Improper store into indexable object" and weird variable names
by Davide Varvello Jan. 19, 2015

Jan. 19, 2015

Hi! It happened that variables of my methods changed to t1, t2, t3, etc etc (see here: http://imgur.com/ptbmzMH ) and when I try to see the versions of a method, pharo shows "Improper store into indexable object" (see here: http://imgur.com/pwWT0yc ). Can you help me, please? I'm on Pharo2.0, Latest update: #20619 Cheers Davide -- View this message in context: http://forum.world.st/Improper-store-into-indexable-object-and-weird-variab… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Blitzkrieg!

What we have with our community: near indestructible
by phil＠highoctane.be Jan. 19, 2015

Jan. 19, 2015

I was reflecting on the PR efforts and the scale and nature of our community. There is one single thing that is our core: we are a bunch of individuals dedicated to Pharo and we deeply like (should I say "love"?) it. That very fact that we are committed to investing in understanding it and making it better, and that, no matter what, makes the community pretty much indestructible. We do not care about fame, we care about something else. Solid, flexible, nimble, ... I don't know. That's a case of QWAN indeed. But Pharo has it. I came on board with 1.3. The progress has been massive. Pharo 4 is going to be a hell of a great piece of software. And things are accelerating. I am proud to be part of the community. I've my moments of doubt. But then there is an inner voice saying: "come on, it can be made to work". And it is true as we have full control on the tool. Just wanted to share. Peace. Phil

[ Article ] LampSort Revisited, Visualised
by Sven Van Caekenberghe Jan. 19, 2015

Jan. 19, 2015

Hi, I wrote another article LampSort Revisited, Visualised Combining Object Logging & Agile Visualisation https://medium.com/concerning-pharo/lampsort-revisited-visualised-6652055ef… It is an introduction and tutorial on object logging using a simple, concrete example, combining that technique with agile visualisation and advanced tools, to get amazing insight into code, easily. It cumulates in a full, animated visualisation as shown in the following screencast movie https://www.youtube.com/watch?v=Rrsm6E7iA9w Thanks to Pierre Chanson, Doru Girba and Alex Bregel for helping me and for their, their teams and the whole Pharo community's work making all this possible. Sven PS: This article is part of the 'Concerning Pharo' collection on medium.com [ https://medium.com/concerning-pharo ], which I maintain. It contains all my medium.com articles that are 'about software development using a pure dynamic object oriented language in an immersive live environment focused on simplicity and feedback'. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

Manners on the list?
by Laura Risani Jan. 19, 2015

Jan. 19, 2015

Hi all, I really appreciate the dedication and effort someone generously put into answering a question. i want neither to waste such a lovely people's time by saying irrelevant things nor to sound harsh or dry to them. It doesn't kind of feel right saying nothing when someone gives me a rather lengthly answer, unless it was the tacit agreement. So i'm facing questions whether or not to make a post, because i'm not sure which are the right/usual manners for this particular mail-list form of communication. My questions boils down to : how/when to provide feedback? If for example i ask a question and receive answers from three people. Should i always answer back ...commenting whether if it worked or not? ...only if it didn't solve my problem or if i had something useful for solving it to add? (like Stack Overflow) Should i answer back in a separate post to each of them or in a single post to all? Are one-line smalltalk comments alright here or should i avoid them? Any other advice on manners is also welcome. A written manifest would be nice :) Best, Laura

Hubcap questions
by HernÃ¡n Morales Durand Jan. 19, 2015

Jan. 19, 2015

Hi all, My goal is to search the contents of the Description form field in SmalltalkHub. I don't know if matches the design and idea of Hubcap (really nice package BTW). I wonder if anyone (Torsten?) tried to download all package metadata first and perform off-line search? Someone posted time ago a list of all repositories, can you share how to do it? Cheers, HernÃ¡n

InfoWorld on Redline Smalltalk
by Stephan Eggermont Jan. 18, 2015

Jan. 18, 2015

continued from pharo-dev, please keep discussion here. The smalltalk on jvm situation is exactly like it shouldn't be. There are three implementations, not working together: - RTalk - Gravel - Redline The first two are driven by existing commercial smalltalk users coming from a platform that they feel is not sufficiently developing (different ones). This amount of fragmentation is ridiculous. Of course they have different priorities and needs, but it should be possible to share the work that all three feel they have to do. The result is that at least two of them move forward very slowly. Stephan

Useful tools?
by Laura Risani Jan. 18, 2015

Jan. 18, 2015

Hi all, What are some tools / plug-ins/ projects / packages / frameworks you find very useful or you use very frequently for development? (please for each name it and state it's purpose) I'm a newcomer to Pharo , so it hasn't to be something rare. On the side... I feel curious about how one gets to know about the existence of such resources. Is there any sort of "resources index" (like a wiki page with categories)? Besides books which can't be comprehensive because of their nature. Such an index would be extremely handy in many ways. Do you agree? Is it plausible, if it doesn't exist, to built it collaboratively? It is a sad thing that useful tools go unnoticed when they could have solved a problem you faced or eased your work if only you've known about their existence. For what i've read on spread posts i feel like there are many such tools. I had this experience of useful resource existence ignorance with TilingWindowManager (LaurentLaffont ) and with RBConfigurableFormatter (by the way i can't figure out how to turn it on). Now i feel like having a multiclipboard would be useful (i have one on my OS but anyway...) Best, Laura

Notification on GC of an object?

Esteban wrote: >you also need to register the object for cleanup, in the WeakRegistry. >(not on my machine, sorry I cannot put an example, but look around) It is simple and here is an example: Create a class: Object subclass: #Bar instanceVariableNames: 'id' classVariableNames: '' category: 'Foo' implemented an #initialize method initialize super initialize. id := UUID new. Transcript show: 'Initialized ', id printString; cr and implemented a finalization method: finalize Transcript show: 'Finalized ', id printString; cr Now in the workspace I instantiate the object: |anObject| Transcript open; clear. anObject := Bar new. Transcript flush.
