[Pharo-project] How can I remove a picture from background ?
by Mariano Martinez Peck Jan. 13, 2010

Jan. 13, 2010

Hi: I do something like this: Form setBackgroundFromImageFileNamed: '/Users/mariano/Pharo/body.png' And the picture is set as background, but then I don't know how to remove it. I look for a while but I didn't find anything. Thanks for the help, Mariano

[Pharo-project] [ANN] Icons for Mac users
by Torsten Bergmann Jan. 13, 2010

Jan. 13, 2010

>I don't know who did the icons. That was me - I used Samuel's logos as a base. I once created them for page 15 (figure 1.1.) of the pharo-by-example book where image, source, etc. files are introduced and made them available via gforge to Oscar Nierstrasz for inclusion in the book. Unfortunately he decided he wanted to have the windows icons, so I made a screenshot of the (IMHO more ugly) win icons which are now included as figure 1.1 in the book. Thanks for the conversion, at least they are used now. Bye T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

[Pharo-project] clone vs shallowCopy
by Bouraqadi Noury Jan. 13, 2010

Jan. 13, 2010

Hi, I found the clone primitive method in the Object class. Its behavior looks the same as shallowCopy. Actually, shallowCopy just sends basicShallowCopy wich calls the same primitive as clone (primitive 148). a1 := Array with: Object new. a2 := a1 clone. a1 == a2. "--->false" a1 first == a2 first. "--->true" When I look to senders (in a pharo-dev 12.2) I find the following: -62 senders of clone. -2 senders of basicShallowCopy -66 senders of shallowCopy Looking to implementors I found: -9 implementors of shallowCopy (all are kernel classes) -1 implementor of basicShallowCopy (not surprizing) -6 implementors of clone (all are kernel classes) Most implementors of clone and shallowCopy are different. Yet, implementations done by same classes are the same behavior. Other implementations of clone answer self, because there are for objects that should/can't be copied (e.g. SmallInteger, Character). So, I suggest to remove clone and use shallowCopy instead (better/more precise name). Anybody has any reeason against? Otherwise, I'll do it. Noury

Torsten, My opinion on the platform attributes (#pharo, #squeak, #gemstone and #squeakCommon) is that attribute should reflect intention. If the code that is being configured is intended to run on all platforms, then using the #common attribute is fine. In the MetacelloRepository, the primary motivation for the configurations is to specify the packages and versions that are to be loaded into the Pharo environment and reflects the decisions made by the Pharo developers. Therefore, it makes a lot of sense to use the #pharo platform for those configurations, because the target environment for the configuration _is_ Pharo. The ConfigigurationOfOmniBrowser is an interesting example. OmniBrowser runs on GemStone, Pharo and Squeak, but the choice of which specific packages to load is likely to be different for each platform (for a variety of reasons). So I don't think there is an absolutely right answer to the question. Besides, even though code is intended to run on all three platforms, over time changes may be made that make in non-portable to one or more platforms, so even with the best intentions... Much like the underlying code base, if the configuration is actively used and maintained, each configuration will eventually find a steady state answer that works. Dale

Torsten, Thanks for the feedback! It is much appreciated.

I am not a professional writer, but basic documentation is required for Metacello, so I have been doing my best. The best way to deal with issues that you find in the code (including the tutorial) is to submit a bug report (http://code.google.com/p/metacello/issues/entry) If you are motivated to work on Metacello, let me know and I will add you as a developer to the repository as well as add you to the Metacello code project (http://code.google.com/p/metacello/) | | | | > 2. there are two special groups introduced in lesson10 | > "default" and "ALL" - why in a different case? | > | > | I don't know. If you read through earlier Metacello communication, you will find that I have admitted that I am poor at naming things (I am not a professional namer either:). For the most part I have listened to and changed things based on feedback. With that said, I have no good reason for the difference. They are two special strings. I prefer bug reports for issues that you deem important, then I won't lose track of them and will be able to address them in due time. | | | > 3. if these are special then it would be nice to | > have | > | > (MetacelloTutorialConfig project version: '1.0') loadAll. | > (MetacelloTutorialConfig project version: '1.0') loadDefault. | > | > | +1 I think I already told this to Dale at my beginning with | Metacello. #loadDefault is already handled. When you send #load to a version, the 'default' group is loaded (if defined), otherwise all of the packages are loaded. I've been holding off adding too many helper methods, not because they aren't useful, but because Metacello is still fairly new. With the Loader in the pipeline, it may turn out that normal users will never have to send messages directly to the configuration...over time if the usage patterns demand helper methods I will definitely add them. | | | > 4. lesson11Author | > Is the author the initials or the full name? | > | > | Which is the difference between Author and Full name ? Don't put | initials. This part of the code was developed while initials were still used on all three platforms (gemstone, pharo and squeak). Pharo has moved to Full Name and on Pharo, the Full name is used ... I happen to do my development with the full name set to my initials so I understand the confusion (see Issue 44: http://code.google.com/p/metacello/issues/detail?id=44) | | | > In Java's Maven POM (Project Object Model, an XML style | > with project infos) one can specify full developer | > informations, which is good when working in a large team: | > http://maven.apache.org/pom.html#Developers | > That is a very good point. The first order priority for Metacello is to take of the functionality first, if it doesn't do the primary job, then it doesn't matter whether the important, but secondary information is included. I agree that there is a lot of useful information that can be added to the project specs and over time it will be added. Dale

>Come on!!! That's not an excuse Yes it is - maybe there is already a better or fixed version in a private repo of dale or the tutorial is not maintained anymore since according to http://code.google.com/p/metacello/wiki/Tutorial there is a real tutorial in preparation. Who knows without asking... >#commonSqueak or something like that , which is for pharo and squeak (but >not gemstone) It's called "squeakCommon" and I have no idea if "gemstone" means the pharo based gemstone image or the server. Anything I see is that FFI config also uses #common and developers for it are Esteban, you and Dale. So you should know ;) However - what if Metacello gets ported. Do we have an "commercialSmalltalksCommon", "vastAndVW", ... or any other combination or do we have to maintain a spec for any each platform. Would'nt it be better to have a spec and tell on which (multiple) targets it is able to run. Questions over Questions ...
