Get list of midi files

[Dan Korneff]

@ustk said in Get list of midi files:

@dustbro Then why not just:

fileList = FileSystem.findFiles(dir, "*.mid", false);

That works too!
Next question. The array of files are Objects. Tips on converting to string so I can load in the MidiPlayer?
The files in the array looks like:

"File: E:\\Company\\Groove 06 - 155 bpm\\Pattern01.mid"

I'm calling

MIDIPlayer.setFile(fileList[0], 1, 1);

and getting an error:

API Call with undefined parameter 0

I guess technically I just need to remove

File: 

from the file name

@ustk @d-healey Any tips on using replace() ?
I'm trying to snip the File: part off of the file name.
using:

fileList = fileList.replace("File: ", "");

but I'm getting the error:

Unknown function 'replace'

[d.healey]

replace works on strings, fileList is an array so no replace function there. You'd need to loop through your array of objects and run replace on each one.

@d-healey here's my attempt:

//hold file list
var fileList = [];
const var formattedNames = [];

const var Browse = Content.getComponent("Browse");

inline function onBrowseControl(component, value)
{
    if(value) //if button clicked
    {
        //open file broswer
        FileSystem.browseForDirectory("", function(dir)
            {
                //push midi list into array
                fileList = FileSystem.findFiles(dir, "*.mid", false);
                
                for (i = 0; i < fileList.length; i++)
                {
                    var newName = fileList[i];
                    newName = newName.replace("File: ", "");
    
                    formattedNames.push(newName);
                }
                
            });
    }
	
};

Content.getComponent("Browse").setControlCallback(onBrowseControl);

getting this error:

function not found
at
 newName = newName.replace("File: ", "");

filelist is an array of objects. So filelist[i] is an object not a string. Try Console.print(trace(filelist[i])); to see what is contained within your object.

@d-healey said in Get list of midi files:

Console.print(trace(filelist[i]));

It returns

Interface: undefined

[d.healey]

@dustbro If you're going to copy and paste things that I write you should check that I've written it correctly ;) Your variable is called fileList, not filelist.

[Dan Korneff]

@d-healey said in Get list of midi files:

fileList

I've been sitting at the computer for 13 hours... maybe I need a break.

Now that I'm using variables that actually exist in my project, it returns empty:

Interface: 

Also, thanks for the help.

[d.healey]

What do you get with Console.print(fileList.length);?

[Dan Korneff]

@d-healey 15, which is the amount of files in my test folder

[d.healey]

Try this in place of your loop

for (f in fileList)
{
	Console.print(f.toString(File.FullPath));
}

I also notice you're using some vars, always use local in inline functions, and in on init use reg or const. 99% of the time var should not be used except in paint routines, mouse callbacks, timer callbacks, and occasionally a few other places.

@d-healey said in Get list of midi files:

Try this in place of your loop

Now we're talking! that returns the file path correctly

[d.healey]

@dustbro Yeah it's late here :) the objects in your array are all file objects so you have access to all of the File class functions, like toString()

Thanks for this advice as well.
