Hi Ed,
This is tricky because some of the UI backends define methods on the old
accessors, eg Cocoa:
TUPLE: pasteboard handle ;
C: <pasteboard> pasteboard
M: pasteboard clipboard-contents
pasteboard-handle pasteboard-string ;
M: pasteboard set-clipboard-contents
pasteboard-handle set-pasteboard-string ;
I think the right approach here is to add a pair of generic words,
GENERIC: clipboard-contents ( clipboard -- string )
GENERIC: set-clipboard-contents ( string clipboard -- )
And two methods for the default implementation,
M: clipboard clipboard-contents contents>> ;
M: clipboard set-clipboard-contents (>>contents) ;
Be on the lookout for accessors which have other methods defined on them.
I'd rather these accessors remained with the 'old style' names, and had
methods to read/write the slot defined on them as above, rather than the
Cocoa UI backend placing methods on contents>> and (>>contents).
The help system is the same; there's an article tuple with a contents slot,
but a few different data types have methods on article-contents.
So in general, you can only replace foo-bar with bar>> if \ foo-bar
see-methods shows no other methods.
