Absolute file paths

[opatut]

Hey guys,

I am making a framework where people can build custom audio visualizers in Löve. I want them to be able to load up their own audio file, i.e. run

Code: Select all

love visualove.love /path/to/audio/file.mp3

and have it played. It seems like love.filesystem does not support absolute paths, neither did I find a way to wrap a userdata object (from io.open) into a Love File Object, which I need to decode the audio. Is there any workaround for this, or do I have to request something similar to be implemented in Löve? I just want to bypass the PhysFS.

Thanks

That is correct.

You can do that with love.filesystem.newFileData.

Code: Select all

love.filesystem.newFileData(myData, "myAudio.mp3", "file")

The mp3 extension in the file name is important in this case.

Thanks. Problem is, who do I get that FileData through the Decoder and SoundData into the SoundSource? The Decoder won't accept userdata, only filenames or Löve files. And love's FileData is not a 'File' object.

I thought I could do this:

io.open -> love.FileData -> love.File -> love.audio.Decoder -> love.audio.SoundData -> love.sound.Source

but apparently I cannot create a love.File from memory.

I even tried copying the metatable from a love.File to my file userdata - but well, that is not allowed from Lua:

I will try to solve it by copying the file to my ~/.local/share/love/ directory via io, then loading it via PhysFS... hope that works.

Ah. I thought one of the functions takes Data objects. It looks like they don't, sorry.
