Re: [Pharo-users] [Pharo-dev] Clickable class side example and initialize methods in Pharo 4.0
Hi Tudor, that should be easy now: look at CompiledMethod#isExampleMethod which can be adopted as needed. Checking for the example pragma could be done this way: self pragmas anySatisfy: [:pragma | pragma keyword = #example ] but we should think first if this is enough. I already proposed to not only annotate with a pragma example but additionally give a category. Like this: example: 'Graphics' example: 'Network' This way we can easily build an example browser for our users where people can go through their point of interest and browse the examples. Maybe we should also rethink pragmas (in Pharo 5.0?) in general to be more Smalltalk like: Example category: 'Graphics' where Example is a real class in the system (!). One can even make it more explicit then ExampleCategory graphics with ExampleCategory(class)graphics returning a translateable string. People can add own categories and one easily knows about already available ones. Now that classes can have properties in Pharo 4.0 already I would like to see a unification for methods and classes here (with the general concept of an Annotation in our metamodel). In my opinion a method pragma is just a special form of annotating a method. And annotating classes is usefull as well (for instance you want to annotate a class with the appropriate Table name in an ORM framework, ...) A comment (in a method or in a class) is also nothing more than a special annotation. A class/method category is also an annotation. If unified a method or a class could be in one or more categories. Even a break point for an expression is IMHO just an annotation. Bye T. Gesendet: Mittwoch, 22.

Re: [Pharo-users] [Pharo-dev] Clickable class side example and initialize methods in Pharo 4.0
Hi, I also disagree with Alex. Examples will become tests (see the work of Markus Gaelli and Adrian Kuhn) and they should be casually connected with the class and intention they test or provide example for. The other thing is that examples should be composable via code. And of course, they should be browsable. They will be close to the class by default, but it does not mean that in the class will be the only way. For example, we can well imagine having helper classes for holding examples, but most classes would not need that I think. As for pragmas, they are a better mechanism for describing intent than a method naming convention is. If nothing else, it lets us freedom in naming the method. It's true that at this point, pragmas are hard to browse, but this will not remain like this for long :) Cheers, Doru On Wed, Oct 22, 2014 at 9:14 PM, stepharo steph...@free.fr wrote: I agree with Thierry but I disagree with Alex :) What is cool is that when you browse a widget class that you get all the examples for this class.

Checking for the example pragma could be done this way: self pragmas anySatisfy: [:pragma | pragma keyword = #example ] but we should think first if this is enough. I already proposed to not only annotate with a pragma example but additionally give a category. Like this: example: 'Graphics' example: 'Network' This way we can easily build an example browser for our users where people can go through their point of interest and browse the examples. Maybe we should also rethink pragmas (in Pharo 5.0?) in general to be more Smalltalk like: Example category: 'Graphics' where Example is a real class in the system (!). One can even make it more explicit then ExampleCategory graphics with ExampleCategory(class)graphics returning a translateable string. People can add own categories and one easily knows about already available ones. Now that classes can have properties in Pharo 4.0 already I would like to see a unification for methods and classes here (with the general concept of an Annotation in our metamodel). In my opinion a method pragma is just a special form of annotating a method. And annotating classes is usefull as well (for instance you want to annotate a class with the appropriate Table name in an ORM framework, ...) A comment (in a method or in a class) is also nothing more than a special annotation. A class/method category is also an annotation. If unified a method or a class could be in one or more categories. Even a break point for an expression is IMHO just an annotation. Bye T. Gesendet: Mittwoch, 22.

This is indeed the way to go. Just to let you know, the example infrastructure is also being developed in the context of GT, so we have a healthy interest overlap which is great. Only in our case, the discovery of the example happens through an example pragma. Would it be possible to change your slice to use this pragma instead of the example* convention?

Hi Doru, Le 22/10/2014 23:03, Tudor Girba a écrit : Hi, As for pragmas, they are a better mechanism for describing intent than a method naming convention is. If nothing else, it lets us freedom in naming the method. And they add another programming language on top of another, and in most cases are redundant with the method name and protocol. i.e. exampleThis has pragma example testThat has pragma test Simply because for the method name to be suitable, it has to convey intent one way or another. I can understand if you come and tell me that the pragma is to annotate for stuff that the compiler can't deduce, such as the #openmp pragmas. But I can't say that bringing in that kind of stuff would mean progress ;) It's true that at this point, pragmas are hard to browse, but this will not remain like this for long :) Tools may help to overcome limitations of pragmas, yes ;) But this sounds like because pragmas may not be that good to start with :) Thierry
