in the pharo by example git hub repository now I check that there is only an emtpy doc and your paper :).

lukas I would love to have a chapter on Rules. I have a starter that I wrote long time ago for the squeak french book but it would be cool if you could add to it.

normally yes. I do not see why it should not. May be we missed some network cleaning of squeak but what do you mean by failing to build.

[Pharo-project] a question about reef naming conventions
by Esteban Lorenzano Nov. 4, 2010

Nov. 4, 2010

Hi, I'm having some doubts about how to call some methods for Reef. To be precise, I'm not sure about the naming og the method extensions I'm adding. For instance, I have an extension for Object, the method #asView, and some others in BlockClosure, #asCallback, asCallbackOn:, etc. So... I want to ask which naming convention is better. 1) Just let the methods like now? 2) adding a prefix, like reView, reCallback, etc.? 3) adding a full name prefix, asReefView, asReefCallback, etc.? What do you think? Cheers, Esteban

[Pharo-project] learning rewrite rules

Nov. 3, 2010

Hi, I am trying to write a rewrite rule to replace something like: browser showOn: #xxx; from: #yyy; using: [ browser list ... browser tree ... ] to something like: browser transmit to: #xxx; from: #yyy; andShow: [:a | a list ... a tree ... ] I managed to do the following: RBParseTreeRewriter new replace: '`@browser showOn: `@target; from: `@origin; using: [ ``@.statements ]' with: '`@browser transmit to: `@target; from: `@origin; andShow: [:a | ``@.statements]'; yourself However, the problem here is that I do not know how to replace all the "browser" appearances with "a" inside the andShow: block. I tried multiple variations like the one below, but I could not seem to get it to work as I want. replace: '`@browser showOn: `@target; from: `@origin; using: [ `@browser ``@.statements]' with: '`@browser transmit to: `@target; from: `@origin; andShow: [:a | a ``@.statements]'; Can anyone point me into the right direction?

Patching XMLNode>>printOn: like that seems to work. XMLNode>>printOn: aStream | writer | writer := XMLWriter on: aStream. >> writer enablePrettyPrinting. self printXMLOn: writer. writer flushMarkup. Now this is clearly not a good solution. I will change my code not to be based on the printOn behavior and use a writer instead. Now I do not understand why we create a writer for each printOn: message Stef On Oct 31, 2010, at 12:03 PM, StÃ©phane Ducasse wrote: > > In my really old code I wrote > > save > "self new save" > > | doc | > doc := self buildXML. > doc printOn: self stream > > > buildXML > > ^ self base asXML > > > Base>>asXML > "BDBase uniqueInstance asXML" > > | doc elem | > doc := XMLDocument new. > doc version: '1.0'. > elem := XMLElement > name: #Base > attributes: > (Dictionary new > at: 'date' put: Date today asString; > at: 'entriesNumber' put: self elements size asString; > at: 'note' put: self note asString; > yourself). > doc addElement: elem. > self elements do: [:each | elem addElement: each asXML]. > ^ doc > > Elements>>asXML > ^ XMLElement name: self class xmlName attributes: self attributes > > > So how can I control that each elements ends with a linebreak/cr whatever? > > Stef > > > > >
