Running the Bespin command line from the, well, the command line

I felt a little masochistic today which left two possibilities open:

1. fix IE6 bugs in (pick any project)
   
2. program in AppleScript

I chose #2.

The following script will execute it's command line arguments as commands inside bespin (if it is running in the current tab of Safari).

on run argv
 tell application "Safari"
  
  set docs to every document
  
  set cmd to ""
  repeat with c in argv
   set cmd to cmd & c & " "
  end repeat
  
  set js to "(function () {if(typeof bespin != 'undefined') { return bespin.get('commandLine').executeCommand('" & cmd & "').output.replace(/]*>/g, '\\n').replace(/<[^>]*>/g, '') } else { return '' }})()"
  
  set out to ""
  
  repeat with doc in docs
   
   set output to do JavaScript js in doc
   
   set out to out & "
" & output
   
  end repeat
  
  out
  
 end tell
end run

Wrap this in a little shell script:

#!/bin/bash
cp bespin.scpt bespin.work.scpt
osascript bespin.work.scpt "$@"

(Don't ask about line two (it is part of the masochism experience :))

... and now stuff like this works:

-bash-3.2$ ./bespin set | grep collab
collaborate = off
