Hi, Geoff. I filed the report. With bracket completion off, I saw no such

Hi, Paul. The best way to set the script may be not to; that is, instead set 
the new object’s behavior to a button that contains the readable script.

Hi, Paul.

The only feature missing is padding the first two words:

   sort tText by pad( word 1 of each ) & pad( word 2 of each ) & word 3 of each


function pad tString
   put "" into item 1000 of tString
   replace comma with space in tString
   return char 1 to 1000 of tString


Does that work for you?

You could scrape an online dictionary to obtain the syllabification for each 
given word.

For example, if you investigate 
https://www.dictionary.com/browse/syllabification 
, you can find the query 
that yielded "syl·lab·i·fi·ca·tion."

You might find other dictionaries that make it easier.

Since order must be maintained, it’s probably faster not to split and sort, and 
faster not to scan the list repeatedly using lineOffset or contains.
You could do it like this:

command removeDuplicates pDelimitedList, pDelimiter
   local tArray, tList
   set the lineDelimiter to pDelimiter
   repeat for each line tLine in pDelimitedList
  if not tArray[tLine] then -- i.e., if this line hasn't appeared already, 
then ...
 put true into tArray[tLine]
 put tLine & pDelimiter after tList
  end if
   end repeat
   delete last char of tList
   return tList for value
end removeDuplicates

Hi, David.

regex supports alternation, so if you put "big dog|big fish" into tTarget then 
you can

filter pText with regex tTarget


Does that work for you?

Hi, Jacque. If you use sets of words, as sDictFile already is, and as Ken 
suggested, then you can eliminate the repeat loop:


split pList by cr into tUserWords
intersect tUserWords with sDictFile into tChecked
difference tUserWords with sDictFile into tNonWords


Does that turn out to be fast enough for you?

Hi, Keith.  You could test each character until you find a tab:

function offsetOfNotTab pString
 local i
 repeat for each char tChar in pString
add 1 to i
if tChar <> tab then return i
 end repeat
end offsetOfNotTab

Since that thread vanished last week, and hasn’t returned, I'm offering help 
here instead.

The list of full paths contains enough information to build an array 
representation of the directory tree.


/**

Summary: Given a list of full paths, and given the partial path they share, 
build an array representing the directory structure

pPaths: a return-delimited list of full paths

pPath: the path that was used to generate the list of full paths

Returns (array): A array with a branch node for each folder and a leaf node for 
each file

Description: Eliminate pPath from every line of pPaths. Then insert each line 
into an array.

email subject "directory tree -> array"

forum topic "f=7=33565"

*/


function arrayFromPaths pPaths, pPath -- a list of full paths, and the path 
that was used to generate the list

local tPaths, tFile, tArray

set the itemDelimiter to "/"


put char 2 to -1 of replaceText( cr & pPaths, cr & pPath & slash, cr ) into 
tPaths -- eliminate pPath from every full path

repeat for each line tPath in tPaths -- insert each file name into the array

put the last item of tPath into tFile

delete the last item of tPath

if tPath is empty then -- the file is in folder pPath

put "true" into tArray[ tFile ]

else -- the file is in a folder in folder pPath

split tPath by slash

put "true" into tArray[ tPath ][ tFile ]

end if

end repeat


return tArray

end arrayFromPaths


on mouseUp

local tPaths = "a/b/c,a/b/d/e,a/b/d/f" -- folder a/b contains file c and folder 
d, which contains files e and f

local tPath = "a/b" -- the shared partial path

replace comma with cr in tPaths


get arrayFromPaths( tPaths, tPath )


breakpoint

end mouseUp




If the topic reappears soon, I’ll repost there because reading code is easier 
there.

By, the way, thanks to RG for the bug report on my earlier posting in the 
now-vanished thread.

"the extents" implements those rules, so "isSequence" doesn’t need to.

Or is there evidence "isSequence" fails?

slightly easier, at least:
function isSequence p

return the extents of p is 1, number of elements in p

end isSequence

Or, if you don’t want to create such parameters to identify your senders, you 
could use the executionContexts:

send "selectionChanged item 2 of line -1 of the executionContexts" to 
 in 

Or, if you want to reduce clutter in your many senders, you could just:

send "selectionChanged the executionContexts" to  in
