Help with Platypus / Cocoa Dialogue...bash rsync script

Platypus is a good way to do this. I've used it for a few solutions. Best thing to do is run one of their example scripts first, confirm all is well and work backwards from there.

I've built several apps in Platypus that also use cocoaDialog as part of its UI elements. The tricks to getting this to work are:

1. Drag cocoaDialog into the Resources section within the Platypus window when setting up the app.
2. Within the script you need to define the path to cocoaDialog with a variable that you can use when you need to call the application.

Here's one way to do it:

## Get script working directory path
workingDir="$(pwd)"

## Set path to bundled cocoaDialog executable
cdPath="$workingDir/cocoaDialog.app/Contents/MacOS/cocoaDialog"

Then later in the script, whenever you need to use cocoaDialog, you do something like:

"$cdPath" msgbox --title "This is a title" --text "Hello" --button1 OK

Once you build the final app, cocoaDialog.app is copied into the MyApp.app/Contents/Resources/ folder.
Doing it this way it becomes a self contained double clickable app that doesn't require a separate dependency of having cocoaDialog installed somewhere else on the Mac.

Using Xcode is easier than it may first seem. By using a basic Applescript program that calls shell functions, you can do quite a lot very easily.

I was hoping to write more, but I have just a very basic blog post that may get you started.
