They are all in experimental pre-beta version, can't really expect them to
be documented yet. Who knows how many changes will happen to them before the
beta is released? However testing them now is the best way to find the bugs
and help improve that code.
The beauty of REBOL is that it isn't hard to find the new functions, with
the power of 'probe, 'echo, 'what and 'source, nothing (except native
implementation) is hidden from us. It's all there for those who want to
explore, it's quite fun really.
But certainly brief documentation of changes would help this testing process
too.
Here are a few more new functions in /view for the curious.
EXISTS-VIA?
- Check if a file is in the cache
FORM-LOCAL-FILE
- Return correct local public path for a URL.,
form-local-file http://www.rebolforces.com/reb/mines.r
== %/c/rebol/view/public/www.rebolforces.com/reb/mines.r
So then other operations can easily be applied to cached files e.g
modified? form-local-file http://www.rebolforces.com/index.r

CENTER-FACE obj -- (Type: any) area -- (Type: any)
- modifies the offset of a face passed to it, to centre that face.
; To center on the screen-face use none for the area arg
view center-face layout [text "center test" button "Close" [unview/all]]
none
; To center within a region, provide a face object for the area arg (to
center over)
;or provide an object that has an offset pair! and size pair!
; this will centre the window between 0x0 and 300x300
view center-face layout [text "center test" button "Close" [unview/all]]
make object! [offset: 0x0 size: 300x300]
CONTEXT - Defines an underived object from a block. Example usage in
vidtest.r
==Changes to existing functions==
SHOW and HIDE
- now accept either a face or a block of faces
CHOOSE
- has a new /window refinement, when used, it means the offset of the choose
popup will be in relation to that parent window rather than to the
screen-face
Hope this helps.
Cheers,
