Jetsam is now open!
I have begun by committing some initial bits and pieces I found lying
around on the beach.
I have a few other ideas to add as and when, for example hooks into a
basic logging add on.
When you contribute to Jetsam please add to the list of
extensions/features in the JetsamSeasidePackageInfo-readmeText method,
and I think that it would be a useful convention to indicate which
version number of seaside2.8 is the current latest to which this
ext 01: WAConfiguration-hasPreferenceGroup;
ext 02: WACachedDocument-clear to ensure next access the document is
re-read from disk.
ext 03: WATagBrush-idNotNil: convenience method for setting ids.
ext 04: WAImageTag-fileName: restore old api, so that it can be used
even though deprecated.
ext 05: WAHtmlCanvas-heading:level: restore old api, so that it can be
used even though deprecated.
ext 06: WASession-download: contents mimeType: mimeType filename: fileName
Enables an anchor to respond with the file content to be downloaded.
ext 07: WADocumentHandler-mimeDocument/response
Enables documentClasses to signal respond with doNotCache by
ext 08: WABatchedList-totalSize accessor
ext 09: WANotCachedDocument - document that doesn't want to be cached in
ext 10: WALibrary names and hence urls are not tied to the class name,
#libraryName can be specified.
ext 11: WAFileHandler-responseAt:ifAbsent:/libraryAt:ifAbsent:
This resolution process enables the libarary resolved by the url
to decide who serves the document.
(the default behaviour is hardwired such that that library class
itself has to serve the content).
ext 12: WAStandardFilesPlus and WAStandardFilesPlusTest
- see class comment for details.
- override seaside defaults in your project, and also serve from
DISK if you wish.
WAStandardFilesPlus class comment:
The majority of seaside projects need to have WAStandardFiles included
otherwise such things as the toolbar cease to display properly.
This class inherits from WAStandardFiles and so by subclassing me, and
adding your subclass to your project (e.g. MyFiles)
you can override the defaults. I also add some features.
Note the following example, in which the filename may be used to
reference a file in your generation code.
html image url: (MyFiles / 'logo.gif').
In standard seaside the file selector form #logoGif would be used. In a
shameless hack which would never be accepted in seaside proper, we
enable both forms. A symbol is assumed to be a selector reference, and a
string is assumed to be a file reference. We do this simply because, in
situations where you may be asking a user to specify a file via a
settings interface, they are likely to be more familiar with the
filename form. The filename form is also cannonical.
Your subclass can also specify whether or not it caches DISK (i.e. not
those stored in a file library method selector aka WAStandardFiles)
based documents, by defining #documentClass. By default we serve
non-cached documents (i.e. we do not cache the document, and we request
that the browser does not either), but once your project is defined you
may wish to change that.
We keep a cache the fileNames of those files we have available to serve
