Hi,
I had occasion to want the starting and ending offsets of a certain chunk. I
toyed with providing new chunklike syntax, such as 'the lineOffsets 1 to 4 of
it'; didn't like it; then hit upon this:
the range of line 2 to 4 of it
Which would return two offsets as comma-delimited integers. It also works for
containers:
container theCont = my title
get the range of word 2 of theCont
It also preserves container opacity -- IE, the 'black bag' effect of passing
a chunk to a handler that accepts containers:
doMyThing item 3 of something
on doMyThing container theCont
get the range of char 2 to 3 of theCont -- would be "2,3", regardless of
what theCont really is
end doMyThing
Is there a 'range' function elsewhere in xland -- does this conflict in any
way? I like it partly because it's friendly and doesn't corrupt the
all-important black bag effect, partly because my compiler makes implementing
this trivial.
