[REBOL] Re: "tabs" in VID
From: anton::wilddsl::net::au at: 10-Apr-2006 2:26
You have discovered the behaviour of LAYOUT which uses
the NEXT-TAB function:
func [tabs way where][
if pair? tabs [
tabs: max 1x1 tabs
return where / tabs * tabs + tabs * way + (where * reverse way)
if block? tabs [
foreach t tabs [
if integer? t [t: t * 1x1]
if all [pair? t (way * t) = (way * max t where)] [
return way * t + (where * reverse way)
100 * way + where
You can see the difference in behaviour between the two modes.
If you supply a pair, it always rounds up to the next tab
even if it is now on a tab (it uses division on a pair! to get
integer division), but if you supply a block of tabs then it does
not round up if it is already now on a tab.
This prevents the possibility of multiple tabs in block mode.
The solution is to change the test to ensure it rounds up by
(way * t) = (way * max t where + 1x1)
After doing this, your examples seem to behave much better ! :-)
I will submit this patch to the RAMBO bug database.
