Lukas, With Gofer-dkh.105, I was able to survive the upgrade from Gofer-lr.83 to Gofer-dkh.105. Gofer-lr.83 was the base version of Gofer used during bootstrapping. The change that broke the camel's back was removing the #version iv from GoferOperation. preGofer-dkh.105 there was no accessor for #version so direct access was required. postGofer-dkh.105 an accessor is required and the loader is used as part of the loading process and my subclass of the loader is there to smooth over the changes that have been made to the Gofer API over time - the code in Metacello needs to be able to run both before and after a new version of Gofer is installed. If we had true "atomic load" we'd be able to survive this set of changes, but without it I'm not sure what can be done other than using different bootstrapping code depending upon which version of Gofer is loaded ... which bangs into the other changes to the API that have been made since Gofer-lr.83. Gofer-lr.83 dates back to pharo1.0-10493 which is when Gofer started to be pre-loaded into the RC1 images. There appear to be versionNumber parsing errors in the older versions of Gofer, that prevent me from using Gofer to determine which package is loaded, so I may have to resort to direct Monticello access to detect the loaded package versions, either that or some kind of check as the the methods that are available in Gofer and infer the "version" of Gofer that is loaded ... Once I have my hands on the "version" of Gofer that is loaded, I can arrange to have the correctly compatible Metacello code loaded on top and we're off to the races.

Re: [Pharo-project] Issue with gofer/metacello
by Dale Henrichs Dec. 27, 2009

The latest Gofer API is not backward compatible with the earlier versions of the Gofer API. This means that I need to have different versions of Metacello to use with the different versions of Gofer. Unfortunately, I can't use Gofer to detect which version of Gofer is loaded because of the API changes. So I will have to write more code than I'd like to detect which version of Gofer is pre-installed. The API changes also impact the bootstrapping code. Solving these problems are a larger project than I can undertake on a Sunday and I _am_ on vacation the coming week as well. So until further notice, if you want to use Metacello 1.0-beta.17 (or earlier) in Pharo you will have to manually ensure Gofer-lr.83 (or earlier) is loaded into your image before attempting to load any Metacello configurations. I'm not sure that you use Gofer to load an earlier version of itself (I'll be finding out in the next few days)... Metacello 1.0-beta.18 works with Gofer-lr.107 (in pharo 1.0-10502). If you want to use Metacello 1.0-beta.18 (currently in development, so it's subject to change). You will have to manually bootstrap Metacello by executing: Gofer new gemsource: 'metacello'; package: 'ConfigurationOfMetacello'; load. (Smalltalk at: #ConfigurationOfMetacello) perform: #ensureMetacello18. ((Smalltalk at: #ConfigurationOfMetacello) project version: '1.0-beta.18') load: 'ALL'. before loading your configuration. I won't release 1.0-beta.18 until I've resolved the bootstrapping problem. I'm pretty sure that there is a technical solution, but it will take several days for me to get it implemented.

[Pharo-project] Happy new year in advance :)

Hi guys I just want to thank you for your positive energy. We had a dream with marcus about a better Smalltalk and this is happening. This is cool. It was not easy but the community is moving - more than we would ever thought after all these years trying to push with less success. Our vision for pharo is described on the pharo web site :) http://www.pharo-project.org/about Now my personal challenge/vision is the following: - I want Pharo to be a cool vehicule for innovation. - I want Pharo to be a solid vehicule for companies to succeed making a living with "Smalltalk" --- I put "" because I would like to avoid to get bound until the end of my life with just a Smalltalk :) but I would love to see companies starting in France around Pharo if you are interested contact me :) Let us really invent the future building on the past. If you want to help, check the mailing-list - you can see our open-process: open and pragmatic communication, discussing and learning are key for us -- sorry for the volume of mails. Spread the word: Pharo is what we will make it to be. Don't always trust what others write between the lines on us. ;-D Check by yourself (drink a beer with us before) and study history - all is in there. Stef

[Pharo-project] Collection>>select: aBlock ifNoneTakeAsDefault: aDefaultValue
by Bart Gauquie Dec. 27, 2009

Dec. 27, 2009

Dear all, While developing some code, I made following extension of the Collection protocol: select: aBlock ifNoneTakeAsDefault: aDefaultValue |result| result := self select: aBlock. (result isEmpty) ifTrue: [^self class with: aDefaultValue] ifFalse: [^result]. Maybe this could be added to the Pharo 1.1 Collection clazz? Or do we want to keep the interface of Collection as small as possible (which is also a good idea!). Kind Regards, Bart -- imagination is more important than knowledge - Albert Einstein Logic will get you from A to B.
