Re: [Pharo-users] Porting GNU Smalltalk code to Pharo

by Miguel Moquillon

I've used Quickcheck with programs in Haskell. IMHA it is the great tool to test codes as we describe the properties of the code to test in terms of invariants or conditional properties. The tool then generates randomly 100 inputs to check the properties; we can indicates the tool to generate more inputs. (We can also specify the generator to use.)

Re: [Pharo-users] Porting GNU Smalltalk code to Pharo

by Andrew Pennebaker

1 - Thanks for welcoming me :) 2 - I generally use the FreeBSD license. In any case, QuickSmash has no license for now. 3 - QuickSmash is an interesting approach to unit testing. The idea is to test "properties", which are lambdas in Lisp and closures in Smalltalk. One property is a closure that accepts an integer and evaluates whether the integer is even. Call it "propEven". Another property checks whether an encryption system works, by checking s = decrypt(encrypt(s)). QuickSmash has a class method testProperty:withGenerators: that generates 100 test cases for the property. If a test case fails, QuickSmash stops checking and reports the values which fail to exhibit the property. Example: "Are all strings reversible?" propReversible := [ :s | s = (s reverse) reverse]. QuickSmash testProperty: propReversible withGenerators: { [ QuickSmash genString. ] }. If you install QuickSmash and evaluate the above code, you'll see the output: +++ OK, passed 100 tests. I'm only just familiar with GNU Smalltalk, but installing QuickSmash is fairly simple. $ git clone https://github.com/mcandre/quicksmash.git $ make (The make command runs gst-package, which loads the package and saves the image).

Andrew First welcome :) Second you should pay attention to the license of the code because GPL is not compatible with Smalltalk in general. Third why quickMash is interesting because I could not get it. Stef On Aug 7, 2011, at 10:20 PM, Andrew Pennebaker wrote: > Can someone help me make QuickSmash Pharo-friendly?

So if he makes the design public, he needs to directly change it again to make his site visually distinct from all the others. As such, giving away the design would mean for doru giving it up and having to invest in a new one. Would not be very intelligent from his side. Marcus -- Marcus Denker -- http://marcusdenker.de

Using Pier as a CMS for a personal site (layouts and urls question)

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I'm reading the Dynamic Web Development (still I'm not in the Seaside list or in the Pier, but I'm already part of Pharo, Squeak, Moose and Aida lists, so I'm trying to subscribe to another community when my interaction and questions get bigger) and I found at the beginning of the section "7.7Rendering Lists and Tables" the skeleton of what could be a personal site. Knowing about the existence of Pier I went to see what personal sites where Pier Powered and I have found many that I like. The one I like most is the Doru site at: http://www.tudorgirba.com/ I really like the layout and colors and is pretty similar to what I would choose for me and I thought that this could be an integrated layout in the options provided by Pier (of course if Doru is fine with that). So my first question is: * Could I use this layout? (pleeeease Doru, pleeeeeeease!!! ;-) ) and how? This could be the base for a different layout with the time (that I promise to share also) but is a really good starting point. * I see the blog on Ramon Leon ( onsmalltalk.com ) without the ugly urls and the Doru's site have clean urls. The method to get them in Seaside is documented in the Ramon's blog. Is the same for Pier (being Seaside based) or there is any other procedure? Thanks in advance, Offray
