I think I did it.
Inside your Rundirex.txt, you should have this snippet:
/RunDir { % Uses PathName variable on the operand stack
{ /mysave save def % Performs a save before running the PS file
dup = flush % Shows name of PS file being run
RunFile % Calls built in Distiller procedure
clear cleardictstack % Cleans up after PS file
mysave restore % Restores save level
}
255 string
filenameforall
} def
Right? If so, then add the definition of a bubble sort routine before
that (which I got from Wikipedia), and then modify /RunDir into the
snippet below. Ghostscript has a .sort built-in that does exaclty
that, but I'm including it here as I don't know if Distiller will too.
% Bubble sort from Wikibooks page on PostScript
/mybubblesort
{ 1 index length 1 sub -1 1
{ 2 index exch 2 copy get 3 copy % arr proc arr i arr[i] arr i arr[i]
0 1 3 index 1 sub
{ 3 index 1 index get % arr proc arr i arr[i] arr
imax amax j arr[j]
2 index 1 index 10 index exec
{ % ... amax < arr[j]
4 2 roll
}
if pop pop
}
for % arr proc arr i
arr[i] arr imax amax
4 -1 roll exch 4 1 roll put put
}
for
pop
} bind def
/RunDir { % Uses PathName variable on the operand stack
/nf 0 def % Reset counter for number of files
{ 255 string copy % Copy to a separate string (otherwise
would be overwritten)
/nf nf 1 add def % Increment counter of number of files
}
255 string
filenameforall
nf array astore % Put all filenames in an array
{ lt } mybubblesort % And sort it
{ /mysave save def % Performs a save before running the PS file
dup = flush % Shows name of PS file being run
RunFile % Calls built in Distiller procedure
clear cleardictstack % Cleans up after PS file
mysave restore % Restores save level
}
forall % Execute original procedure, but
using sorted array
} def
Of course I did not test it with Distiller which I don't have... I did
test the part of sorting the list of files with Ghostscript and it
works.
Maybe word wrapping in the e-mail will ruin the snippet, if that's the
case please let me know and I'll send it attached to you.
Let us know if that works!
