Re: [Pharo-project] Refactor source method is grayed out?

Hi, OCompletion forked the code from ECompletion and it now builds on it. I think the reason for this fork was that at the time when Romain started there was nobody really maintaining ECompletion. But, it would be great to have just one completion mechanism. I highly suggest to take a look at the new OCompletion: now it is fast and in most situations it provides significantly better suggestions than ECompletion. What's more the ECompletion-based suggestions are also available in a reasonable manner.

Re: [Pharo-project] Poll: missing libraries to support business

by GermÃ¡n Arduino

Hehe, that (or similar) was allways on my mind. In the past I started a project I named SDA (Smalltalk Developer Assistant) focused on lot of things that may be shortened as "Code Generation" :) as Genexus does. One more time, the lack of free time and the need of focus the time on payed projects did their work and the project is almost abandoned....but I agree that a tool that could do somethings automagically would help in 2 areas: 1. Attracting more people, and 2. Make the life of current Smalltalkers a bit more easy :) GermÃ¡n. 2010/8/3 laurent laffont <laurent.laffont(a)gmail.com>: > On Mon, Aug 2, 2010 at 9:50 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > wrote: >> >> Hi guys >> >> with the experience around the XMLRPC project, ESUG wants to change >> strategy to help growing business at the technical >> level.

Thanks tim. > Guys - this is my first attempt at a contribution - and I'm not sure how literally to take the advice on "how to contribute to Pharo" for a small change. Should I create an issue, and post it here (happy to do that, but wondered if conversation might be useful first as I'm new to this). always create an issue else we forget.... too much stuff to do. Then conversation is always good. Because we build a shared mindset and we all learn together Now since this is for an external package you can add lukas on the field and he will get notified. > Given that I'm not sure what the relationship between eCompletion and oCompletion is (someone mentioned the latter is built on top of the former?) - so maybe I'm barking up the wrong tree, however I was impressed with how much quicker Lucas' Hudson built pharo image was with eCompletion so I've been trying that for a few days (although I've noticed some mails on oCompletion but haven't gone back to retry it). > > Anyway - I have attached a change set that changes how smart characters work - instead of turning them off because half of the time they do the wrong thing for me and I madly press delete, I wanted to preserve the other half of the time when I'm entering new code and they give me a helpful template. > > My proposed fix is for the following scenario - if I go to add an extra bracket around an expression (becuase I later realise that I need to designate a keyword expression) I get two brackets - and then I backspace and they both go, so then I do it again and press delete...

But still I don't understand. I didn't understand your comment: "The store segment primitive does not consider class references from objects with compact class as external pointers" In addition, look this example: testOutPointersWithSpecialSharedObjects | anObject segment root a| anObject := TestResult basicNew. anObject timeStamp: Date dateAndTimeNow asString. root := Array with: anObject. segment := ImageSegment new copyFromRoots: root sizeHint: 5000 areUnique: false. self assert: segment outPointers size = 1. self assert: (segment outPointers includes: nil) Of course, this is failing, and the outPointers is: {TestResult. nil}. I don't understand why the CLASS TestResult is there. So..for every simple object I store, it will also store its class? I really really read the primitive to store and try to understand the very low levels. But I cannot see where (image side or primitives) the class can be added to outPointer, nor why. I think it shouldn't be included. Because it is NOT referenced from inside my subgraph. Maybe there is something I am not seeing. I am getting nervous hahahah Now, another question. Date dateAndTimeNow asString answer a ByteString something like this: 'an Array(3 August 2010 12:40:17 pm)' It is ok that this variable is NOT in the outPointers, because it is ONLY accesible from the subgraph. But now, if I change to this: anObject timeStamp: 'an Array(3 August 2010 12:40:17 pm)'. Then outPointers size is 3 and it is: {TestResult. 'an Array(3 August 2010 12:40:17 pm)'. nil} grrrrrrr is that when building string in this way it is referenced from some other place? Thanks!!
