timeStamp :(
by StÃ©phane Ducasse Aug. 27, 2010

Aug. 27, 2010

we got burned because CompiledMethod>>timeStamp returns a '' when the compiled method has not timeStamp instead of a TimeStamp. What we did we systematically created a timeStamp for a MethodReference and suddenly changeStamp size > 0 broke in the following method because it was not expected a time stamp We are puzzled because this code should not work when a MethodReference has a timeStamp. So probably it was only use without timeStamp.... :( Stef printCategoryChunk: category on: aFileStream withStamp: changeStamp priorMethod: priorMethod "Print a method category preamble. This must have a category name. It may have an author/date stamp, and it may have a prior source link. If it has a prior source link, it MUST have a stamp, even if it is empty." "The current design is that changeStamps and prior source links are preserved in the changes file. All fileOuts include changeStamps. Condensing sources, however, eliminates all stamps (and links, natch)." aFileStream cr; nextPut: $!. aFileStream nextChunkPut: (String streamContents: [:strm | strm nextPutAll: self name; nextPutAll: ' methodsFor: '; print: category asString.

Robust flatten for collection?
by Simon Denier Aug. 27, 2010

Aug. 27, 2010

Hi there A question to test your sagacity :) I'm looking for a method which would flatten a collection, regardless of whether the collection is already flat or not. that is: #((1 2 3) (4 5 6)) flatten --> #(1 2 3 4 5 6) #(1 2 3 4 5 6) flatten --> #(1 2 3 4 5 6) #((1 2 3) 4 5 6) flatten --> #(1 2 3 4 5 6) Any idea about the best implementation for this? -- Simon

In that case, it would appear that for whatever reason, Noury and I have images with a smaller Special Objects Array than you. Could you check if that is correct, or if for whatever reason, the packages you are installing, are not looking for Alien to be inserted at slot 53?

Pharo by Example - Lights Out
by Phil Lewis Aug. 26, 2010

Aug. 26, 2010

Hi, I'm trying to work through PBE, and have got to the LightsOut chapter. It appears that SimpleSwitchMorph is not part of the image. I found some old posts in the archive about this, but they just seemed to be mentioning something about putting a disclaimer in the book. Is there any way I can progress with this tutorial? Thanks -- Ram Ram

Since some of you are newcomers to smalltalk or may be did not know the value of pharo core people here is a first draft I wrote this morning thinking about pharo http://code.google.com/p/pharo/wiki/PharoZen * Beauty in the code, beauty in the comments * Simplicity is beautiful * Communication is key * Classes structure our vocabulary * Messages are our vocabulary * Polymorphism is our esperanto * Better small polymorphic classes than a large ugly one * Tests are important but can be replaced * Abstraction and composition are our friends * Explicit is better than implicit * Magic only at the right place * Simple processes to support progress * One step at a time * There is no unimportant fix * Quality is a emerging property * A system with robust abstractions that a single person can understand Stef Please comment also on the wiki.
