Posted a new C# library to Github to allow the calling of AppleScript by function name, passing in arguments and receiving a return value.

Sushi.AppleScript

https://github.com/sushihangover/Sushi.AppleScript

The C# library allows you to execute AppleScript code that originates from a file or string and:

Call function by name (Optional)
Pass multiple arguments to a function (Optional)
Execution success or failure
Return results from the function call

Build:

cd Sushi.AppleScript.Native
xcodebuild
cd -
xbuild Sushi.AppleScript.sln

Test:

Mono’s supplied nunit-console:

MONO_IOMAP=all nunit-console Sushi.AppleScript.Test/SushiAppleScript.Test.csproj

NUnit 3.x console:

mono $(MTOOLS)/nunit3-console.exe Sushi.AppleScript.Test/SushiAppleScript.Test.csproj

Note:

AppleScript.cs(7,7): error CS0246: The type or namespace name `MonoMac' could not be found. Are you missing an assembly reference?

If you do not have a local copy of MonoMac, xbuild will fail. It is available via “Xamarin Studio”:

mdtool build Sushi.AppleScript.sln

Example Usage:

var scptInfo = new FileInfo ("./AppleScripts/FunctionTests.txt");
string funcName = "IsRunning";
List<string> argList = new List<string> () {
    @"Finder",
};
string scriptReturnValue;
var executionSuccess = AppleScript.Run (scptInfo, funcName, argList, out scriptReturnValue);

Consult Test.cs for more examples

Supports:

MonoMac
Xamarin.Mac
i386 and x86_64 Mono Support

Runtime/Deployment debugging:

Runtime/Deployment debugging available by setting an environment variable, APPLE_SCRIPT_DEBUG:

export APPLE_SCRIPT_DEBUG=true

The results are logged with the prefix AppleScript:, output is avaiable via Console.app.
