The details have to be determined yet, it mainly helps to ensure  
extensibility and avoids to have naming conventions; probably there  
are other possibilites:

* Magritte-Descriptions

- Now: There is a naming convention that all descriptions have to be  
put on the class-side of the model and that their selectors should  
look like #description[A-Z][A-Za-z0-9]+. Not only this is extremely  
ugly but also forces other packages to override, if they want to  
extend another package.

- Pragmas: It should be possible to define descriptions within  
different methods, so that different packages are able to customize  
the same description. Probably there are This could look like:

EditPage class>>contentsDescription (core package)
        <description>

        ^ MAMemoDescription selector: #contents

EditPage class>>contentsDescriptionComponent: aDescription (seaside  
view)
        <description: #contentsDescription>

        ^ aDescription componentClass: PRContentsEditor

EditPage class>>contentsDescriptionPersistency: aDescription  
(persistency paackge)
        <description: #contentsDescription>

        ^ aDescription persistencyStrategy: PROmniPersistent new

* Pier-Parser

- Now: The Pier-Wiki parser right now is quite limited, because  
extensions cannot modify or extend its behaviour without duplicating  
everything.

- Pragmas: I would like so simplify it so that it triggers sub-
parsers from line prefixes. These prefixes are defined as method-
pragmas so that other packages are able to add their own extensions.

Any other ideas?

Hi :)

I haven't been there for a week... and I see there are big changes in
Magritte...
I had an error while loading the last version  Magritte-All-lr.148  
(because of MACachedBuilder>>modified) I had the 142 version before... I
also cant access the last test package version on monticello... so I'm
thinking of preparing another image... Is it possible to remove all
magritte related stuff and install a brand new one ( I have empty
categories  etc...). What is the "best way" to have a brand new magritte
? :)

You are getting rif of MACachedBuilder ?   there is
MADescriptionBuilder, Pragma...Named  ...  Is there something important
here to know or is it more about renaming and preparing pragma in magritte ?

Thanks

Cédrick

No, no, not so big.

Argh, this is due to a problem of Monticello being unable to load  
code from a newer version itself. If you experience problems loading  
code with Monticello retry with the latest version of Monticello.

I guess it is the best to stick with your old code for now, there is  
nothing that changed much.

No, I just renamed the classes.

- MADescriptionBuilder is the new common superclass of the builders.

- MANamedBuilder is the new default builder that works about the same  
as the old MACachedBuilder.

- MAPragmaBuilder is an experimental builder taking the descriptions  
from Pragmas, it should be loadable in old versions.

Cheers,
Lukas
