Hi Pierce Ng How different is the API from Seaside? Because I would like to use it. I like to think modularly :) Stef On Mon, Sep 11, 2017 at 12:31 PM, Pierce Ng <pierce(a)samadhiweb.com> wrote: > On Fri, Sep 08, 2017 at 03:15:56PM -0700, Sean P.

Re: [Pharo-users] Standalone HTML Model

by Esteban A. Maringolo

I don't know how modular it is, but maybe loading only the 'Seaside-Canvas' package you can use the WAHtmlCanvas to create the HTML content. I used it together with Mandrill client by creating the mail body with the result of `WAHtmlCanvas builder render: [ :html | ... ]`. HTH. Regards, Esteban A.

Re: [Pharo-users] New chapter for coming book: Messages

by H. Hirzel

Hello Stephane I like the emphasis of the chapter that implementing same selector several times at the proper place in a couple of classes is more important than to rely on inheritance. In particular the conclusion <citation> What is important to realise is that classes are cheap. It is better to write 5 little classes than a huge one. Some (even smart) people got confused by measuring complexity of a system using number of classes. Having many classes representing good abstractions with a single responsibility is much much better than having a single class exhibiting multiple responsibilities. </citation> Suggestion: put it into a 'Note' box. And replace 'got confused' with: 'get confused' Replace: Now the choices can be made over multiple tenth of classes. 'multiple tenth' is an uncommon expression Suggestion: Now the choices can be made over dozens of classes. However 'Sending a message is making a choice!' takes the view point of the mechanism which does the late binding. If I write aNode emitHTML: aStream I do not make the choice. There are different types of nodes and they all do the same in the sense that they produce HTML code. In any case to drive the point home more examples are needed. The Boolean example is the minimal example and as such is interesting. But it is a borderline case which just illustrates that Smalltalk goes a long way to implement the object and message pattern consistently. The Pillar example is fine but too terse. For people who already understand the issue just a reference is fine. But for people new to the concept of replacing a case statement with a class hierarchy it is too short. Elaborate! E.g. have a diagram for a subset of the hierarchy PRObject #(''properties'') PRDocumentItem #(''counter'') PRDocumentGroup #(''children'') PRDocument #() PRHeader #(''level'') PRList #() PROrderedList #() PRUnorderedList #() PRParagraph #() PRReference #(''reference'' ''parameters'') PRFigure #() PRSlide #(''title'' ''label'') PRText #(''text'')' And show all the emitHTML: messages. And go for a third example, e.g. from Morphic or Bloc position: extent: color: owner: submorphs: drawOn: aCanvas Meaning of last sentence is not clear. <citation> Remember that when we execute a method (and also write it), one key information we get is that the receiver from this class or one of its subclasses as we will later. <citation> Regards Hannes On 9/11/17, Ricardo Pacheco <ricardo.pacheco.roldan(a)gmail.com> wrote: > Looks Great, congratulations!!
