Re: [Cocoadialog-users] Bourne Shell Script Equivalent to Perl Script Sample for CocoaDialog Dropdown

[Thomas P. <tp...@gm...>]

Hello Bill:

Thanks again for the alternate approach.  I see how cut may be much faster
and more lightweight and fast solution.  I just made a syntax error when
trying to implement it last time.  My project is integrating CocoaDialog and
Platypus to create a simple drag and drop run application with the ability
to take graphical user input.  At this point, I am not 100% sure that the
users want so I am just playing with the basics.  You might wan to mention
the synergy between CocoaDialog and Platypus (both are open source) as it
has worked out well for me and might for others as well.

Thanks again for the help.   Once you get the details down, CocoaDialog is a
very simple way to add graphical input to such drag and drop application as
those that I am making.

Cheers,

Thomas
