You could skip some of the looping.
set inputText to " ...
What looping?
I was referring to Nigel's last method. While yours is expeditious, it's
also overzealous. Adding spaces and removing punctuation.
set s to " email@hidden 'This is a > string?' "
set AppleScript's text item delimiters to {space}
set s to "" & words of s
set AppleScript's text item delimiters to {""}
return s
-->"fred @ boop.dot.com This is a > string"
His handles this but iterates on every text item of the text delimited
by a space. My suggestion iterates over some percent of the characters
to be removed.
given...set s to " email@hidden 'This is a > string?' "
NG's requires 14 iterations while mine takes 6. Over a larger text or
text with greater numbers of spaces it becomes very significant. It
requires contiguous white space of 160 characters before more than 21
iterations are required by my version.
I realize now that the version below is more efficient requiring only 15
loops to handle the 160 character run text...
set inputText to " email@hidden 'This is a > string?' "
cleanSpaces(inputText)
-->"email@hidden 'This is a > string?'"
on cleanSpaces(inputText)
set tag to "o#?"--opt shift k
set inputText to tag & inputText & tag
repeat while inputText contains " "
repeat with thesedelimiters in {{space & space, tag}, {tag & tag,
tag}, {tag, space}}
set AppleScript's text item delimiters to item 1 of thesedelimiters
set tempS to text items of inputText
set AppleScript's text item delimiters to item 2 of thesedelimiters
set inputText to tempS as text
end repeat
end repeat
set AppleScript's text item delimiters to ""
return (characters 2 thru -2 of inputText) as text
end cleanSpaces
This version will clean up space runs in the text of this entire posting
in 6 loops vs 433 for Nigel's.
