Re: [Pharo-users] How to set the server debugger in seaside?
Stef, You know you can contribute and improve it? You should remember a bit more the talk of Kim Mackinnon in Cambridge… This negative way of talking about work of others is not the way to get things done. I don’t think you would appreciate someone mailing this way about the Pharo interface. In 3.2, the debugger exception handler is the default for development. There is also the programmatic way of changing this: (WAAdmin defaultDispatcher handlerAt: ‘YourApp’) exceptionHandler: WADebugErrorHandler cheers Johan > On 04 Feb 2016, at 22:42, stepharo wrote: > > Thanks this is so inintuitive that I forget 5 min after. > > Le 2/2/16 09:56, Cyril Ferlicot Delbecque a écrit : >> On 02/02/2016 09:47, stepharo wrote: >>> Hi guys >>> >>> I hate so much this bad configuration interface of seaside. >>> I lose all the time 20 min to find how to set the debugger. >>> So I have to do a presentation and I cannot show the debugger. >>> What a great wonderful experience. >>> >>> How can I configure seaside to get the debugger? >>> >>> Stef >>> >> If I remember well on http://localhost:8080/config add a Filter.

The code base is common between 32 and 64 bit images. It is possible to run a 32 bit image without the class SmallFloat64, but it is not the default behavior. There are no instances of SmallFloat64 in 32 bits and there can't be any. There are details, such as the SmallFloat64 class needs to be present to convert a 32 bit image to 64 bits with the offline converter and if the code base remains common between 32 and 64 bit images, then the specialObjectsArray will hold a reference to SmallFloat64 which needs to be updated if one removes the SmallFloat64 class. For servers and desktop application it does not really make sense any more to remove these classes in 32 bits as they represent very few kb compared to Gb of RAM for laptops and Tb for servers. The Smalltalk image is already much smaller than let's say, the JVM default runtime. In addition, most computers are 64 bits now so it usually does not make sense to release in 32 bits. On embedded devices, one can consider deploying without classes such as SmallFloat64 or LargeInteger to minimize the memory footprint. The support for such feature is not very good currently, but it is getting slowly better. It could make sense to remove such classes if you are targeting a connected object with let's say an ARM Cortex-M4. This is part of a larger problem which consists in making the Pharo Kernel modular so that we can load only part of it in specific contexts to save memory or to reduce the system capabilities. 2016-02-02 14:43 GMT+01:00 Werner Kassens mailto:wkass...@libello.com>>: On 02/02/2016 02:30 PM, Sven Van Caekenberghe wrote: Maybe those classes could exist in a 32-bit image as empty subclasses of float ? that is, what i hope werner
Re: [Pharo-users] Spec doc

Re: [Pharo-users] Scrollbar in Spec layout
If I understand correctly, you are adding a lot of labels dynamically to the window, and you want a scrollbar to appear to the window, correct? I am afraid that this scenario is not supported by Spec. Instead you should use a list and add items there. Then you will get the scroll bar for free. Note that you can configure the list so that nothing can be selected, so the visual look will be more or less the same.
