[MacPerl] Update to cli4mp (AppleScript front end)
For anyone who cares, I've updated my "cli4mp" AppleScript to be a bit
more friendly and fix a glaring ommision. The changes are documented in
the revision comments. One of the changes should allow the script to
pass through emailers OK, now, though it still uses some special
characters. Sorry, some of the lines are longer than 80 characters, so
watch out for forced line breaks. Just copy the source (below) into a
new script window and save as an application. Read the comments for more
details.
Let me know if you have any problems, complaints, or suggestions...

-- cli4mp
--
-- v1.1 (24 Mar 1999)
-- > AppleScript no longer waits for the MacPerl script to terminate.
-- > New I/O directive added for choosing an output file.
-- > I/O directives can now be quoted with \.
-- > I/O directives changed to be intuitive, yet email friendly.
-- > Removed clunky / funky file loops. I think users would very rarely
-- need to input an arbitrary number of files or folders and
if they would,
-- they would prefer file globbing with wild cards! Uhh... no
I haven't
-- implemented that yet!
--
-- v1.0 (11 Mar 1999)
-- Original version.
--
-- What it does, in a nutshell:
--
-- (1) The user drops a perl script on the cli4mp icon.
-- (2) cli4mp puts up a dialog prompting for the command line arguments.
-- (3) cli4mp tells MacPerl to execute the dropped perl script using the
-- command line as arguments.
-- (4) MacPerl does whatever your script tells it to with the ARGV list.
--
-- However, it's not quite that simplistic. First, cli4mp passes most characters
-- to MacPerl indiscriminately, with a few exceptions.
--
-- (1) Space characters are the argument delimiters and are not passed unquoted.
-- (2) The backslash (\) is the quote character and forces the next immediate
-- character to be inserted into an argument.
-- (3) There are three special characters that behave as I/O directives.
-- (a) The Option-backslash character (Ç) tells cli4mp to request
an input file
-- from the user with a StandardFile dialog. Use a '\' to
quote Ç.
-- (b) The Option-shift-backslash character (È) tells cli4mp to
request an
-- output file from the user with a StandardFile dialog. Use
a '\' to quote È.
-- (c) The Option-f character (°) tells cli4mp to request a folder from
-- the user with a StandardFile dialog. Use a '\' to quote °.
--
-- Well, I've done some reasonably thorough testing, but I can't
guarantee that
-- there's not something still broken in there somewhere. Feel free to
send me bug
-- reports.
--
-- LIMITATIONS
-- > Only one file can be dropped on cli4mp at a time.
-- > Dropped files must be a valid, functional perl script... duh!
-- > Both AppleScript and MacPerl must be installed... double duh!
--
-- As usual, no warrantees expressed or implied.
