Creating a new folder in documents directory

kussakov

Hi,

I want to create subdirectories in my documents ("|D|") directory where I want to save/delete some files.
I can't figure out which API to call to create a new directory.

Could you help please?

Thanks

Vlad

@kussakov - I'm not 100% sure, but as no-one else has stepped in, I'll have a go, and bump the question anyway.

I don't think you can. Googling "lua create folder", brings up a number of stackoverflow answers which state this in various ways:

The Lua design philosophy is to be pure ISO C, so as to be portable to anything with a C compiler. There is no directory creation function in the C standard library. This is left up to platform-specific extensions, like mkdir(2) on POSIX systems and CreateDirectory*() on Windows.

So I would guess that creating a folder is dependent upon which operating system you are using.

You can easily do it through plugins. Have you tried plugins yet? Are you working on Android or iOS?

@kussakov - Also, I just noticed this thread:

Thanks Caroline!
I also googled a lot before adding the discussion :-)
Bassically we should wait for next releases to create and browse directories.

Just an idea, but if you try to open file in write mode, which doesn't exist, it's automatically created right?

So what if you tried to open file, which doesn't exist inside folder which doesn't exist?

Something like:

--open file local file = io.open( "|D|mydir/myfile.txt", "w" ) --store something file:write( "something" ) --close file io.close( file )

I'm not at my PC right, so can't try it. Just an Idea

As a thought - if you can't create folders, perhaps you could come up with some naming convention that you can parse and filter like folders,

e.g. If you want a folder called "saves" and inside it you want to create files tempa.dat, tempb.dat etc you'd just call the file saves_tempa.dat and saves_tempb.dat

Just my $0.02

@ar2rsawseen - I just tried your idea - it return NIL file

@techdojo - Right, I can do something like what you suggest. Basically do my own pseudo directory management and make sure the names are unique. I was just trying to avoid doing that...
