[Pharo-project] Cleaning morphic?
by Guillermo Polito July 16, 2010

July 16, 2010

I know morphic is one of the greatest issues Squeak and Pharo have. And I'm tired of the kilometric morph hierarchies with tons of methods that noone uses, and the impossible traceability of the morphic code... And I'm sure that a lot of people tried it before... And this isn't the highest priority. But I think morphic cleansing should be done. So, while i'm now in bed beacause of a flu, hehe, I want at least remove unused morph classes and unused methods... Or maybe we can separate some things from the core. Of course I will be "spamming" in the list asking for the changes I will do :P. what do you think? Do I open a ticket? Guille

[Pharo-project] VM more flexible for research?
by Mariano Martinez Peck July 15, 2010

July 15, 2010

Hi folks. I am a newbie for both research and VM. However, in the little time I have been working on this, I always need some extra bits in the object header to do some experiments. And the problem is that I always have only one :( So I come to the idea of having a more flexible VM for the people that want to experiment with it. The first idea was to remove compact classes. But of course, there may be much more ideas or things to do. What do you think? Cheers Mariano

[Pharo-project] Evaluation of Pharo for Commercial Project
by Torsten Bergmann July 15, 2010

>We are used to VisualAge and VisualWorks, which clearly shows the >structure of packages in the browser Do you know O2 browser for Pharo? It's an additional browser that shows the packages similar to VW. See [1] and ask on the pharo list to get the right version for your image. >We are uncertain how packages are made and how they show up in Monticello. Monticello is simple - an MCZ is just a ZIP including the code. Monticello (ab)uses class/method categories to find out which package the code belongs to. Packaging is simple: in short if you create a package "MyApp" in Monticello any class that is in a class category that starts with "MyApp" will be in this package. Example: a) class "MyClass" in class category "MyApp-Core" and b) class "MyModelClass" in class category "MyApp-Core-Model" and c) class "MyTestCase" in class category "MyApp-Tests" 1. When you create a Monticello package (in the Monticello browser) called "MyApp" automatically all three classes (core and tests) are then into this simple package (click on "Browse" to verify) 2. If you want core and tests in separate packages you create two packages "MyApp-Core" (automatically including a and b) and "MyApp-Tests" with c. Method extensions: If you put a method in a category with a leading star and your package name it gets included too. So if you put a method #foo on String into the method category "*myapp-core" it is a method extension on String packaged in "MyApp-Core" package. If you have well named packages this works good and even works in the large. Typically packages are stored in repositories (www.squeaksource.com repo server, local (shared) directories, FTP, ...) Read the http://pharobyexample.org/ book to get more info on Monticello. Also check out http://pharocasts.blogspot.com/ > Since we are unable to organize our code in packages, controlling and > verifying dependencies between them is hard. This is adressed using METACELLO (which manages Monticello packages) - think of Monticello to provide packages and Metacello as configurations to manage which package (version) depends on which other package (version) You just describe baselines (structure and dependencies) and versions that fit together in a class/package called "ConfigurationOfMyApp". See [2] and [3] and the ProfStef teacher workspace that comes with Pharo to learn more. If stuck just ask. Namespace support and better Breakpoint support will (hopefully) adressed in the near future. Also better packaging. Bye T.

[Pharo-project] material for thought
by StÃ©phane Ducasse July 15, 2010

July 15, 2010

Lessons learned by the seaside lead! from http://blog.fitzell.ca/2010/07/seaside-3-release-candidate.html â¢ When your wonderful, dedicated users start putting your code into production, they're telling you it's ready to be released. Listen to them. â¢ We don't have the manpower to carry out the kind of QA process that goes along with an Development, Alpha, Beta, RC, Final release process. â¢ We need to figure out how to get more users actively involved in the project. This could be by writing code but probably more importantly by writing documentation, improving usability, building releases, managing the website, doing graphical design, or something else entirely. The small core team simply can't handle it all. I think that the point three concern .... you :) If you want really pharo to be a success you should from time to time step back from your keyboard and think about the little actions that you can do to make pharo better and we all can do something.

[Pharo-project] CPU load on Pharo
by Dario Trussardi July 15, 2010

July 15, 2010

Hi, i work with MAC update to: Versione sistema: Mac OS X 10.6.4 (10F569) Versione kernel: Darwin 10.4.0 My Pharo image is based on gemtools-1-0-beta-6-one-click-available/ download from: > > http://gemstonesoup.wordpress.com/2010/05/28/gemtools-1-0-beta-6-one-click-… > I update the Pharo image with: Seaside 30 Magritte2 and Pier2. After i port my code and do some work for seaside 3.0 integration. Now when i test the application ( WAKom startOn: 8080 ) the MAC report a CPU load of 5% + 3 %. After some work : ( web request to my application - other web request - Pharo source change - other Mac application ( word -excel ), but only if Pharo image is load, the CPU load go to: CPU User 35 % CPU system 40% . For now i don' understand because this load. When i close the application ( Pharo - Safari - ....) the load of CPU don't change ( 35% + 40% ). For solve it i need to restart the Mac. Someone found this problem ? Thanks, Dario

But it opened my image and ran the script... Some time ago I modified the VM to allow setting the error code from within the image before exiting so you could check a return value from a batch file or vbscript, etc... It turned out I didn't need it at the time, but I've always thought that should become part of the VM. Of course, it requires a new primitive as well... Let me know if I didn't try what you are asking... Rob > > Cheers, > Doru > > -- > www.tudorgirba.com > > "What is more important: To be happy, or to make happy?" >
