FileSystem.findFiles(var directory, String wildcard, bool recursive)

[Lindon]

So I'm using this call...or trying to....

sadly it takes a few seconds to return the array of file names....so really it would be better to have this

FileSystem.findFiles(var directory, String wildcard, bool recursive, function(){

})

but meanwhile... how is every one dealing with the waiting game - a timer?

[Christoph Hart]

No, actually that's a good request, since the scripting engine is not supposed to wait for multiple seconds (which is why all of those things require an asynchronous function call).

I just wasn't aware that this operation might take more time, because I only tested it with small amounts of files, but I can imagine that it will take a bit if you have thousands of files (or if you have a slow USB drive or whatever)

Yeah - Im testing on a "slow USB drive" to make sure I catch this sort of thing...

My vote is for the callback, breaking change is okay with me :)

@d-healey @Lindon
Hello, is it possible to iterate in an array that contains the files using the findFiles function?

var filesArray = FileSystem.findFiles(mydirectory, "*.format", false);
Console.print(filesArray); //prints "[Array]"

The moment I try to iterate over the array to see if the files are correct, it gives me error or prints nothing.

for (i in filesArray)
{ Console.print(filesArray[i]);  }//API Call with undefined parameter

Any ideas? Thanks

@Sawer You're misunderstanding how the for in loop works.

[Sawer]

@d-healey Uhh, right! I figurdìed it now. Thanks for the catch!

for (i in filesArray)
{ Console.print(i);  } //Nothing comes out now

What about this?

[d.healey]

@Sawer i is a file object, so what do you expect the output to be? Also probably better to use f instead of i, or even the word file to be really clear about what the object is.

[Sawer]

@d-healey An object and its id, maybe? something like "Object 0x3b35018" ?

for (file in filesArray)
{ Console.print(file);  }  

Here you go :)

Probably it's a kind of different object, I get it.
Is there a way to stringify it and get the name of the file?

[d.healey]

@Sawer Type File in the API browser to see all of the functions that are available for File objects.

[Sawer]

@d-healey Thanks.
Do spaces in a path make the function not to work? because it's still now working. I'm wondering if it is that

[d.healey]

@Sawer Spaces in the paths are fine. Are you sure your array has been populated (use the script watch table to check)?

[Sawer]

@d-healey True, I checked now and after I Compiled, the array is not yet populated.

[Sawer]

@Sawer
Do all files work or only text files? Because I just want to get the name of each sample file in the project sample folder, using the FileSystem API.

[d.healey]

@Sawer All files, but the samples won't be in the project folder on the user's system.

Do your samples have a .format extension?

Perhaps use this function

[Sawer]

@d-healey the format was just an example name: the wildcard is "*.wav"
Will try that function now and give you a feedback. Thanks

[Sawer]

@d-healey For instance, I'm now trying the same thing with an XML, and still the array is not populated. Strange..

[d.healey]

@Sawer Need to see more of your code to know what you're doing wrong.

[Sawer]

@d-healey True.

inline function fetchSamplesDirectory(component, value)
{
   if (value == 1)
     FileSystem.browseForDirectory(FileSystem.Desktop, function(folder)
	{
	   if(isDefined(folder) && folder.isDirectory())
			{
			  var samplesPath = folder.toString(folder.FullPath); //samples directory variable
				
			  var samplesArray = FileSystem.findFiles(samplesPath, "*.wav", false); //Array of samples 
				
                          Console.print(samplesArray);
			}	
	});
};

I have not been iterating over the array cause it's still not populated.

[d.healey]

@Sawer You don't need to pass a string to the findFiles function. Just pass in the folder variable.
