Sorry for the late reply, but I'm catching up after some time off for my
daughter's wedding….
This might be useful:
function lineOffsets str,container
-- returns a comma-delimited list of all the lineOffsets of str in cntr
-- duplicates are stripped out
-- requires offsets()
put offsets(str,container) into offList
if offList = "0" then return "0"
repeat for each item i in offList
put the number of lines of (char 1 to i of container) into lineNbr
put 1 into A[lineNbr]
-- using an array avoids duplicates
end repeat
put the keys of A into loList
sort lines of loList ascending numeric
replace cr with comma in loList
return loList
end lineOffsets
function offsets str,container,includeOverlaps
-- returns a comma-delimited list of all the offsets of str in container
-- returns 0 if not found
-- third param is optional:
-- offsets("xx","xxxxxx") returns "1,3,5" not "1,2,3,4,5"
-- ie, by default, overlapping offsets are not counted
-- if you want overlapping offsets then pass "true" in 3rd param
if str is not in container then return 0
if includeOverlaps = empty then put false into includeOverlaps
put empty into offsetList
put 0 into startPoint
repeat
put offset(str,container,startPoint) into thisOffset
if thisOffset = 0 then exit repeat
add thisOffset to startPoint
put startPoint & comma after offsetList
if not includeOverlaps then
add length(str)-1 to startPoint
end if
end repeat
return item 1 to -1 of offsetList -- delete trailing comma
end offsets
You could get the lineoffsets of each string and run a repeat loop to set the
color of the lines.
