I like that, changing it. Now available at https://github.com/gcanyon/alloffsetsOne thing I don't see how to do without significantly impacting performance is to return all offsets if there are overlapping strings. For example: allOffsets("aba","abababa") would return 1,5, when it might be reasonable to expect it to return 1,3,5. Using the offset function with numToSkip would make that easy; adapting allOffsets to do so would be harder to do cleanly I think.
Can I suggest changing it to "someOffsets()" :-) :-) But seriously, can you not iteratively run "allofsets" ? something like .... (typed straight into email - totally untested) function allOffsets pDel, pStr repeat with c = 1 to 255 -- or some other upper limit ? if NOT pDel contains numtochar(c) then put numtochar(c) into c exit repeat end if end repeat repeat forever put someOffsets(pDel, pStr) into newR if the number of items in newR = 0 then exit repeat repeat for each item I in newR put c into char I of newR end repeat put newR after R end repeat sort items of R numeric return R end alloffsets -- Alex. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
