There are several of ways to do something like this and it's fairly
trivial as
long as you have a little patience in exploring your options. Here are
a few
things that come to mind:
(1) Work entirely within AppleScript:
Here's a basic start for a script that you can develop further:
property theCommand : ""
tell application "BBEdit"
tell window 1
set currentSelection to selection as string
set theCommand to text returned of ¬
(display dialog "Enter shell command:" ¬
default answer theCommand buttons {"Execute"} ¬
default button 1 with icon 1)
try
set theOutput to ¬
(do shell script theCommand & " '" & ¬
currentSelection & "'") & return
on error errMsg number errNum
beep
display dialog "Error: " & errNum & ". " & errMsg ¬
with icon stop buttons {"Cancel"} default button 1
end try
set selection to theOutput
end tell
end tell
(2) Use BBEdit Unix Filters, avoiding AppleScript altogether:
Without AppleScript, it's more difficult to collect input from a
GUI prompt.
But you could write a Unix Filter for all the shell commands you
want to
perform, where only the text to be processed varies.
Or, if the commands themselves vary as well, you could type them
in BBEdit
and pass them along to a Unix Filter as part of the input. Then
"eval" the
entire thing from within your shell script.
Here's an example of the latter approach using Python (but you can
use any
language you want):
#!/usr/local/bin/python
import fileinput
import string
import os
if __name__ == "__main__":
cmdResult = ''
for my_line in fileinput.input():
cmdResult = cmdResult + os.popen(my_line).read()
print cmdResult
(3) Combine options 1 and 2 above:
This is an AppleScript I threw together a while back and never
really
finished, so there's lots of room for improvement. But the basic
idea is to
execute the selected text as a shell command, like we did in
option 2 above.
The difference, however, is that because it uses AppleScript, we
can do some
fancier things: use a different interpreter based on the source
language of
the current document ('php -r' for PHP code, 'perl -e' for Perl,
'ruby -e'
for Ruby, etc.), display GUI error dialogs, and have more
flexibility in how
the returned text is presented.
Give it a try if you're interested, and feel free to modify it to
suit your
needs.

(4) Use a BBEdit shell worksheet, a special document type that allows
you to
store and execute Unix command lines. See page 322 of the BBEdit
User Manual
for more information.
Hope this gives you some ideas.
