Autocompletion in MPW

One very useful feature of many Unix shells is that you only need to type the beginning of a command, hit tab, and it fills in the complete command. I was really missing this on MPW, especially with long command names such as UnobsoleteNameRevisions.

So here's a script that attempts to provide this feature in MPW, as well as possible. Bind it to Command-Tab (or whatever you want), then type "nam", hit Command-Tab, and watch it fill in "NameRevisions" for you.

Note: if nothing is selected, it will try to complete the last word on the current line. If you want to complete a word in the middle of a line, you'll have to select it.

If ":" is in your {Commands} variable, it will also consider all files in the current directory, as I have found no way to figure out whether a file is an MPW script or not. Actually, this may even be useful.

# get the current selection
Set CurrentSelection "'Catenate "{Active}".§'"

If "{CurrentSelection}" == ""
   # select the entire line we're on
   Find !0 "{Active}"
   # put the insertion point at the beginning of this line
   Find Δ§:Δ§ "{Active}"
   # remember line number, so we can restore it later
   Set CurrentLine 'Position -l "{Active}"'

   # select the last word on this line
   Find /[¬ ∂t∂n]+[ ∂t]*∞/ "{Active}" || (Beep; Exit 0)

   # if it isn't really on our current line, exit
   If 'Position -l "{Active}"' != {CurrentLine}
      Find {CurrentLine} "{Active}"
      Beep
      Exit 0
   End

   Set CurrentSelection "'Catenate "{Active}".§'"
   # strip spaces from the end, if any
   If "{CurrentSelection}" =~ /([¬ ∂t]+)®1[ ∂t]*/
      Set CurrentSelection "{®1}"
   End

   # can this happen at this point?
   If "{CurrentSelection}" == ""
      Beep
      Exit 0
   End
End

# a list of matching command names
Set CommandList ""
# the number of matches found
Set Matches 0

# first see if it's one of the built-in commands
