hahahahha your next step is to build a framework to build tutorials hahaha. Seriously, this is very good material. We need to take care about newcomers, and this is an excellent way as also your videos. Cool to have it in next dev image :) 2010/1/21 laurent laffont <laurent.laffont(a)gmail.com> > I've just released in MetacelloRepository the milestone I've wanted to > reach.

I forgot to said: after installing O2 in that image, when you open a System BRowser, it will ask which one do you want as default.

Michael: sorry, I just read the email. What we will really appreciate is that you report EACH problem you have. Like this you are telling about O2. This is the only way we have to progress. If nobody reports...so, thanks for reporting, and keep doing that. In Pharo, you can have several System Browsers: - The default you have in a PharoCore image. Very limited but fast. - OB (omnibrowser) is better than de default, with several features, refactoring tools, etc. It doesn't manage packages, thus. Now, it is the default in dev images. - O2 browser, that has package support and was the standard at the moment the book was wrote. It seemed to be too slow, and for other reasons, it was changed the default, to OB. We will releasing a new image very soon (maybe this weekend). But, for the moment, if you don't care you can download the latest PharoDev image for BetaTesting from here: https://gforge.inria.fr/frs/download.php/25156/pharo1.0-10505-rc1dev10.01.1… There you will have the OB as default, as I explained you, but...you will be able to install O2 in that image. To install O2, evaluate in a Workspace, the following code: Gofer new squeaksource: 'MetacelloRepository'; package:'ConfigurationOfO2'; load. (Smalltalk at: #ConfigurationOfO2) perform: #loadDefault. The next Pharo image, will have a welcome workspace specially for new people, with tutorials and with the pieces of code ready to install commong projects such as O2, Seaside 2.8 and 3.0, Magritte, Pier, Moose, etc... I would really appreciate if you can give us your feedback for that. Cheers and welcome!

Re: [Pharo-project] Question about ImageSegment, Symbols and SmartRefStream

by Mariano Martinez Peck

Ahhhh I got it :) The trick was where Lukas said: readSymbol "PRIVATE -- Read the contents of a Symbol." ^ self readString asSymbol but....I realised that, String >> asSymbol is: asSymbol "Answer the unique Symbol whose characters are the characters of the string." ^Symbol intern: self And...Symbol >> intern: intern: aStringOrSymbol ^(self lookup: aStringOrSymbol) ifNil:[ | aClass aSymbol | aStringOrSymbol isSymbol ifTrue:[ aSymbol := aStringOrSymbol. ] ifFalse:[ aClass := aStringOrSymbol isOctetString ifTrue:[ByteSymbol] ifFalse:[WideSymbol]. aSymbol := aClass basicNew: aStringOrSymbol size. aSymbol string: aStringOrSymbol. ]. NewSymbols add: aSymbol. aSymbol]. that's why I don't get duplicates!!!

The symbol table is a *weak* set and hence if you don't strongly hold onto the symbols they get into the segment array and not into the out pointers! This is a potential source of subtle problems because after loading the segment you end up with duplicated symbols (we run into this with Cmsbox...). The easiest solution is to create a temporary variable and assign "Symbol allSymbols" while creating a segment. Ok, but that is done at several places in ImageSegement.
