ps2pdf droplet

The long running gag around here is I use old software that works with old hardware. Fun. Recently I was sent a PostScript file to output to film, but the version of Distiller I use choked on it. Illustrator CS2 could open it, but unbeknownst to me it only imports the first page. More fun.

Inkscape will import PostScript files and will ask you which page you’d like to open. Unfortunately Inkscape version 1.1 on macOS will not because… reasons?

Luckily the tool it uses to convert PS to PDF still works– ps2pdf. If you have Ghostscript installed you should have ps2pdf available as well.

This AppleScript is set to use ps2pdf installed via macports.

Of note is replacing the “.ps” extension using text item delimiters. Relevant lines being:

set my text item delimiters to {"."}
set target_path to (text items 1 thru -2 of source_path) & "pdf" as string

I’ve seen people write complete paragraph weight routines to do that, so tuck this away in your bag-of-tricks. 😉


-- Path to your ps2pdf script.
property path2ps2pdf : "/opt/local/bin/ps2pdf " -- Don't forget the trailing space!
