Re: How to find the offset of the last instance of a repeating character in a string? (Geoff Canyon)
Here is something... probably needs some optimization
function allOffsets2 D,S,pCase
local dLength, C, R
-- returns a comma-delimited list of the offsets of D in S
set the caseSensitive to pCase is true
set the itemDel to D
put length(D) into dLength
put 1 - dLength into C
if dLength > 1 then
local n, i, j, D2, L2
put 0 into n
repeat with i = 2 to dLength
if char i to -1 of D is char 1 to -i of D then
add 1 to n
put char (1-i) to -1 of D into D2[n]
put i-1 into L2[n]
end if
end repeat
end if
repeat for each item i in S
if C > 0 and n > 0 then
repeat with j = 1 to n
if i&D begins with D2[j] then
put C+L2[j],"" after R
end if
end repeat
end if
add length(i) + dLength to C
put C,"" after R
end repeat
set the itemDel to comma
delete char -1 of R
if item -1 of R > len(S) then
if the number of items of R is 1 then
return 0
else
delete item -1 of R
end if
end if
if char -dLength to -1 of S is D then
return R
end if
repeat with j = n down to 1
if char -len(D2[j]) to -1 of S is D2[j] then
delete item -1 of R
end if
end repeat
return R
end allOffsets2
I think a couple of private functions would be good. One for 0 overlap,
one for a single overlap, then a final general one for any number of
overlaps (the core of the above). After the loop that generates D2/L2 I
would branch based on n to avoid the additional comparisons inside the loop.

something like (typed straight into email - totally untested)
function allOffsets pDel, pStr

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

I like that, changing it. Now available at

One 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

Re: Sorting datagrid column with a tricj?
Okay, looks like this is a no go. I read from one of the datagrid lessons in reference to populating the datagrid "by hand": Important: When using this technique properties like dgData, dgText, dgDataOfIndex, etc. will no longer return values. The data grid is just displaying records from your data source. It does not store any of that data internally. What I would like to see added to the datagrid is a handler that intercepted the population of a field so what goes into the field can be custom formatted. This comes up a lot. Dates and numbers from an SQL query are unformatted, and having to go through the datagrid when populating and formatting each record's data before displaying it, and then reformatting it before pushing it back up to the database seems like more work than necessary.

Re: Sorting datagrid column with a tricj?
In a table datagrid, can't you edit the column template so that you can control what goes into the field for that column? I think the underlying data will remain the same, but what goes into the field is what you put there. I suspect the datagrid will then sort by the underlying data, not the displayed data. I have a similar issue with SQL formatted dates, but I want to display them as long dates. I'll toy around with this and see what I come up with.

Re: Sorting datagrid column with a tricj?
There is no way I know of to have a datagrid sort by an invisible column and still show that it is sorted by a visible one. Every time the datagrid "redraws" it's going to update the appearance of the header to reflect the sort. If you want to force the sort when you populate the datagrid, then set the dgProp ["sort by column"] of the datagrid to the column you want, and then if the user sorts by a different column, well that's on them.

Re: How to find the offset of the last instance of a repeating character in a string? (Geoff Canyon)
All of those return a single value; I wanted to convey the concept of returning multiple values. To me listOffset implies it does the same thing as itemOffset, since items come in a list. How about: offsets -- not my favorite because it's almost indistinguishable from offset offsetsOf -- seems a tad clumsy On Fri, Nov 2, 2018 at 7:41 AM Bob Sneidar via use-livecode < use-livecode@lists.runrev.com> wrote: > It probably should be named listOffset, like itemOffset or lineOffset. > > Bob S > > > > On Nov 1, 2018, at 17:04 , Geoff Canyon via use-livecode < > use-livecode@lists.runrev.com> wrote: > > > > Nice!
