While, John's suggestion of using a UNIX filter is a bit cleaner than
this AppleScript + Clipping stuff, the unfortunate thing about UNIX
filters is that if you don't have anything selected, it operates on
the entire text of the selection, which might not be what you want.
That's no impediment. You can simply check the length of the
selection and do nothing if that is 0. Then send the command to run
the filter.
set _asf to path to application support folder from user domain as string
set _tfilters to _asf & "BBEdit:Text Filters:"
set _scriptfile to "e2*.pl"
set _script to alias (_tfilters & _scriptfile)
tell application "BBEdit"
if length of selection is 0 then return
run unix filter {_script}
end tell
I have held for a long time that AppleScript should be used for
little routines that only AppleScript can do, in this case
determining whether anything is selected. When you consider the
verbosity and contortions needed to work with text using BBEdit's
AppleScript dictionary compared with the speed and simplicity of
using Perl etc. there is simply no contest. Perl can't put up
dialogues or close and measure windows and things like that, so
that's where you use AppleScript. Once that is done, pick up the
better tools.
All that "do shell script" stuff is a pain as well, what with the
need to escape quotes etc. but where it's unavoidable the I find the
following syntax the most convenient, since it removes that extra
single-quoted level that you need if you do perl -e 'etc':
do shell script "perl <<END
print qq~Goodbye cruel world!~;
END"
