Where to set a session locale?

I am currently working with a group of master students of software
localization at Anhalt University on project to localize seaBreeze, the
seaBreeze editor, seaBreeze documentation, seaBreeze tutorial and on a
framework to create multilingual seaBreeze applications easily.

Thus I looked into Seaside how to embed our ideas and I got pretty happy:
Seaside 3.0 has all the infrastructure needed to create multilingual web
applications. VisualWorks UserMessage lookup uses Seaside session
information to get to the right locale. That's all great.

Now I have a question: Where shall I set the session locale? Actually my
idea is to initialize it from the 'accept-language' property of the
WARequest if it is not yet set in the session. I think the statement should
look like this:

        self someMessage session locale ifNil: [self someMessage session
locale: (self someOtherMessage request acceptLanguage)]

Hints are welcome.

Georg,

If you load Seaside-I18N you'll have access to a new filter that sets the locale for the session via,

self session locale: #en_CA

The only catch (and it's a biggie that I hope Cincom addresses soon given their push for web applications) is that current versions of VisualWorks do not support multiple message catalogues per-image out-of-the-box. I have the following hack in place to get around that,

MessageCatalogManager class>>updateCatalogs

        | id manager |
         id := Locale current languageID.
         manager := self new: id.
         MessageCatalog withAllSubclasses do: [:class | class catalogsDo: [:catalog | manager add: catalog]].

and I manually force load of all catalogues via,

MyApplicationRoot class>>refreshCatalogs

        | path |
        path := '.\messages' asLogicalFileSpecification.
        (IndexedFileMessageCatalog directories includes: path)
                ifFalse:
                        [IndexedFileMessageCatalog directoriesModel
                                value: ((IndexedFileMessageCatalog directories)
                                                add: path;
                                                yourself)].
        IndexedFileMessageCatalog compileAllCatalogsInSearchDirectories.
        MessageCatalogManager.Managers values do: [:ea | ea flushCatalogs].
        [self supportedLanguages do:
                        [:lang |
                        Locale current: lang locale.
                        IndexedFileMessageCatalog updateDirectories.
                        MessageCatalogManager updateCatalogs].
        UserMessage flushCaches]
                        ensure: [Locale current: self supportedLanguages first locale].

Hope this helps,

-Boris

Boris,

Thank you. My question was slightly different: Where to place the
initialization of the session locale taken from the settings in the browser
as transferred in the http request?

Georg,

Ah,

YourApplicationRoot>>initialRequest: aRequest

        super initialRequest: aRequest.
        self session locale: #en_CA.

You could then pick a proper locale using the information gleaned from "aRequest acceptLanguage".

-Boris
