The File Filesystem (2021)

Oh this is cool! I recently wrapped libfuse in Nim and after porting the 'hello' filesystem example I made one which is more or less exactly this. However my version you pipe data and have to provide a mountpoint, then when it's done it writes the result over stdout. That means you can inline it in a pipe chain but also that you have to make sure to grab the output.

At the moment I'm exploring other stuff which could be made into file systems. I've got a statusbar thing for the Nimdow window manager which allows you to write contents to individual files and it creates a bar with blocks on them as the output. It makes it super easy to swap out what is on your bar which is pretty neat.

Another tool I've made is a music player. It uses libvlc and when given a folder it reads all the media with ID3 tags and sets up folders like 'by-artist', 'by-album', etc. Each file is named as '<track number> - <song title>' and contains the full path to the actual file. To play a song you cat one of these files into 'control/current' and write the word play to 'control/command'. There's a bit more to it like that like a playlist feature and some more commands, but that's the basic idea. The goal is to have a super-scriptable music player.

Would you mind sharing the Nim code? I've been interested in working with FUSE for a while, and use Nim for a few projects.

No worries if not, I'm just curious!
