Copy & Save '.mid file' to 'folder' || Help.

@Chazrox Pass in a File object.

For example


inline function copyMidiFile(original)
{
    local filename = original.toString(original.Filename);
    local newFile = FileSystem.getFolder(FileSystem.AppData).getChildFile(filename);
    original.copy(newFile);
}

Chazrox

@d-healey Thank you! I'll try this now.

Chazrox

@d-healey no errors but its not working..
can you spot it?

 original = FileSystem.fromAbsolutePath(full); // full is the full filepath name from the file dropped. 

    if (original == undefined)
    {
        
    }
    else
    {
        local filename;
        filename = original.toString(original.Filename);

        local appDataDir;
        appDataDir = FileSystem.getFolder(FileSystem.AppData); 

        local newFile;
        newFile = appDataDir.getChildFile(filename);

        original.copy(newFile);
        original.move(appDataDir);

        Console.print("Saved copy to AppData: " + newFile.toString(newFile.FullPath));
    }

@Chazrox

In what way is it not working?

// Why the empty if statement?
if (original == undefined)
{        
}

// Each of these can be one line
local filename;
filename = original.toString(original.Filename);

local appDataDir;
appDataDir = FileSystem.getFolder(FileSystem.AppData); 

local newFile;
newFile = appDataDir.getChildFile(filename);

// Why are you copying then overwriting it with the original?
original.copy(newFile);
original.move(appDataDir);

Chazrox

@d-healey

Why the empty if statement?

I had something there but deleted it. I just removed it.

Why are you copying then overwriting it with the original?

I dont know what Im doing lol. I was just trying things because it wasnt working.

When I drop the .mid file on my panel, the rest of the script executes but this part of it doesnt. I dont see any files in AppData or any other directory that I test.

Can you show me where you are calling your function?

@d-healey complete mess at the moment but have a look.

@Chazrox I'd start with some Console.prints to see where the processing is getting up to. Is the filename you're storing what you expect it to be, is original a file object - instead of == undefined, use if (isDefined(original) && original.isFile()) to be certain.

Chazrox

@d-healey ok. I'll check all of that now.

Chazrox

This is where im at now, still not working completely. All of the functions work in this code block except for the part where I want the dropped file saved to the AppData folder. Can anyone help with this please?

Scroll down a little bit...

none of my .prints return any results in that section either.

Ok lets start with your code...



    // PARSE BASE NAME
    local full = obj.fileName;   
}

and later:

local original = FileSystem.fromAbsolutePath(full);

So you are taking the filename from the obj and (later)asking for the actual file using .fromAbsolutePath()

..but absolute path wants just that - an absolute path not the file name....so something like C:\documents\myfolder\myfilename.mid

so this:

local original = FileSystem.fromAbsolutePath(full);

is probably failing - I think. so this:

if (isDefined(original) && original.isFile())
    {

    etc. etc...

is going to return false - and not execute....you need to do a LOT more Console.print debugging....

like this:

//! onPnlMIDIFilesFileDrop ---------------------------------------------------------------
inline function onpnlMIDIFilesFileDrop_B(obj)
{
    // HOVER STATE
    prevHover = this.data.hover ? 1 : 0;

    this.data.hover = (obj.hover && !obj.drop) ? 1 : 0;

    if ((this.data.hover ? 1 : 0) != prevHover)
    {
    	this.repaint();
    }

    // HOVER CHECK
    if (obj.hover && !obj.drop)
    {
        this.data.text    = "Drop to load!";
        this.data.dropped = false;
        this.changed();
        return;
    }
   
    if (!obj.drop || obj.fileName == undefined)
    {
    	return;	
    }

    // PARSE BASE NAME
    local full = obj.fileName;   
    local slash = Math.max(full.lastIndexOf("/"), full.lastIndexOf("\\"));

@Lindon said in Copy & Save '.mid file' to 'folder' || Help.:

local filename = original.toString(this.data.Filename);

also whilst we are here, Im not sure you can say this:


	local filename =  original.toString(this.data.Filename);

what I think you mean is this:


	local filename =  original.toString(original.Filename);

But its not going to work anyway until you get a file into original, not a text string...

Chazrox

@Lindon bro Thanks!

Im gonna check this out right now and report back.
I really appreciate the time brotha!

These are a bunch of new api's for me so im sure I made alot of mistakes and asking chat gpt to help sometimes make things worse. lol

I really should.

Chazrox

@Lindon

I was setting my B panels callback to my A panel....thats why none of my prints were hitting. When I was dropping on panel B, Panel A script was running which is already doing what it needs to do fine.

uhggh.. lol.
its one letter sometimes messing your whole day up. haha.

const var pnlMIDIFiles_B = Content.getComponent("pnlMIDIFiles_B");
pnlMIDIFiles_B.setFileDropCallback("All Callbacks", "*.mid", onpnlMIDIFilesFileDrop_B);

Your prints you added are extensive and im going to follow that from now on! Thank You sir! Im getting alot of info from these prints which I should help big time. Again

@Lindon @d-healey I GOT IT.

After going through all the debugs I figured it out. Thank you guys so much. This was the last function I needed for my plugin which is just save a history of dropped files...and aside from some visual tweaks.....IM DONE!! Im on to the next step. Now i'll be buggin you guys about code-signing soon. haha. Thanks so much!

Chazrox

I'll be sharing a cleaned up snippet version and make an example of this for anybody that might be looking for it. Thanks again guys!
