Hi Rick,
sorry to come back to this issue. I've the script working:
#!/bin/sh
#
# Removes trailing blanks (spaces and tabs) and save to file.
osascript << ENDOFSCRIPT
tell application "Xcode"
set myFile to associated file name of front window
set textDocuments to text documents
repeat with i in textDocuments
if path of i is myFile then
set orgText to text of i
set text of i to do shell script "echo " & quoted form of
orgText & " | tr '\r' '\n' | perl -pe 's/[\t ]+$//g'"
save i
end if
end repeat
end tell
ENDOFSCRIPT
exit 0
tr first converts from CR to LF line endings, then perl strips off all
trailing tabs and blanks from each source line and then the text is put
back in the editor. However, the "set text of text document" does convert
all \n to \r even strings like "\n", which is not a binary \n.
So running the script on:
void a()
{
printf("bla\n");
}
sets the text back in the editor like:
void a()
{
printf("bla
");
}
How can I prevent this behaviour?
Many thanks for any help.
Cheers, Fons.

do shell script "perl -pe 's/[\t ]+$//g' " & quoted form of myFile &
" > ~/.xc-save.$$; mv ~/.xc-save.$$ " & quoted form of myFile
end tell
ENDOFSCRIPT
but this leaves my editor window empty since no buffer gets written
back in. But as soon as something gets written back in the buffer is
modified, hence not saved. Is there a catch-22 here?
Hi Fons,
I'm not completely sure I understand what you mean. Xcode won't notice
that you've overwritten the file on disk right away, so maybe that's
what you're seeing. Switching applications will trigger a refresh of the
file on disk, as will closing and re-opening it.
You don't need to replace the file on disk in order to modify its
contents, however; you can manipulate the text of the document directly
via applescript. If you browse Xcode's scripting dictionary in script
editor and look at the Text Document class, you should see what you
need. Specificially, you can "set text of front text document to"
whatever you want.
