[ANN] Test Coverage with Hapao
by Alexandre Bergel Sept. 21, 2014

Sept. 21, 2014

Dear all, We are happy to release Hapao2 for Pharo. Ricard Jacas and Alejandro Infante put quite some work on Spy2 (an Ã¼ber cool profiling framework for Pharo) and Hapao2. Hapao2 is about assessing the test coverage of your code and is a major revamp of Hapao1, which was presented a couple of years ago by Vanessa. Hapao2 does not only list covered and uncovered methods, as most test coverage tool on Earth will do. Hapao gives a great visualization to easily navigate in your code, assess its complexity, and give you a great visual output telling its coverage. You need Roassal in your image: Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load and you need S2py: MCHttpRepository location: 'http://smalltalkhub.com/mc/ObjectProfile/S2py/main' user: '' password: '' New entries will appear in the world menu: You can run the test coverage on : - the class classes you have modified, - on a particular - on a particular class category - on the last class categories you have modified - on the last packages you have modified Here is a portion of a large coverage: A technical description of Hapao may be found on http://bergel.eu/download/papers/Berg12c-HapaoSCP.pdf We are daily using Hapao to help us understand our tests.

Booting into Pharo!
by Mayuresh Kathe Sept. 20, 2014

Sept. 20, 2014

Hello, While I am still waiting for my copy of the PBE, I would like to initiate work on a project (along with friends). The idea is to build a minimalist Linux based system which would boot up straight into a full-screen Pharo environment. The system itself would be single user, consisting of not more than a Linux kernel, a few system utilities (busybox?), X (KDrive?) and Pharo (vm + image + ...). Would like to know if it's some how possible to control external programs from within Pharo, essentially shell scripts for network setup, etc. Thanks, ~Mayuresh

Preorder tree traversal
by Offray Vladimir Luna CÃ¡rdenas Sept. 19, 2014

Sept. 19, 2014

Hi, I have a tree object structure, in a project and I'm wondering if there is a code or method that I can use to make a preorder tree traversal on it. I have seen the one that is the book Inside Smalltalk Vol 1, but I don't know if there is something in the image or elsewhere that can be used without much/any reimplementation. So, any pointer to a solution? Thanks, Offray

>The idea is to build a minimalist Linux based system which would boot up >straight into a full-screen Pharo environment. Why use a Linux underneath when you can do it in Smalltalk ;) Look at SqueakNOS - an operating system that was/still is able to boot from disk right into Squeak: http://wiki.squeak.org/squeak/1762 Accessing devices/writing drivers in Smalltalk, etc. >Would like to know if it's some how possible to control external >programs from within Pharo, essentially shell scripts for network setup, >etc. Check out the "OSProcess" package in Pharo.

Where pharo stores its selfies?

Theme : Choices : Good, but ...
by Mayuresh Kathe Sept. 19, 2014

Sept. 19, 2014

It's been close to 6 hours that I've been playing with the defaults offered with Pharo 3. Everything works so much more smoothly than Squeak! It also feels great. What's kind of problematic (as I see it) is the "look". There are 3 themes that I got with the default image; Pharo 3, Vistary and Watery. Look good, but somehow give off the feel of having more style than substance. I remember using something called Java Swing long back. It too had a plethora of themes, but the one that was the most detailed, and well designed (as in how well it worked), was something called "Java Steel". Please see the images at; http://docs.oracle.com/javase/tutorial/figures/uiswing/lookandfeel/OceanLAF… https://today.java.net/images/2004/02/laf_fig2.gif If there could be some way to have that look and feel, while adhering to the Java LaF Guidelines for the same, we might have a Pharo system which would be not only neater looking, but also lighter weight (by virtue of fewer extravagant graphical properties). Hope this suggestion isn't preposterous. :) ~Mayuresh

No one wants to look like Swing... Also people would then think we do static typing ;) Bye T.

ServerDirectory replacement
by Markus Fritsche Sept. 19, 2014

Sept. 19, 2014

Hello, I'm revisiting some old code that I started to sort my favorites on my tv settop box. I noticed that ServerDirectory is gone. I naively replaced ServerDirectory by FTPClient, but I get an error that the iv stream is nil. So I looked at the comment of FTPClient - which recommends me to look at ServerDirectory. What is the proper way to log in to a ftp server, get a file and disconnect? getHD1File: aFilename | ftpClient byteString | ftpClient := FTPClient new. ftpClient host: 'coolstream'. ftpClient loginUser: 'neutrino' password: 'holycow'. byteString := ftpClient getFileNamed: aFilename . ftpClient quit. ^ byteString => MessageNotUnderstood: receiver of "sendCommand:" is nil Kind regards, Markus
