FilterFS

A small FUSE-filesystem to mirror another directory (RO), but filter it slightly based on file endings.

Install

Compile

git clone git@github.com:teo8192/filterfs.git
cd filterfs
cargo build --release

Install

sudo cp target/release/filterfs

To mount a RO mirror that only shows m4b and pdf files:

mount -t fuse.filterfs /source/directory /target/directory -o 'incl=*.m4b,incl=*.pdf'

Pass no options to have a RO mirror of all files.

incl=glob include files matching glob
excl=glob exclude files matching glob
dincl=glob include directories matching glob
dexcl=glob exclude directories matching glob
prune=n how deep to recursively look for empty directories to prune. Default is 0, i.e. no pruning. Beware that pruning may cause performance losses, especially if the underlying directory contains a lot of directories again.

There are still some permission trouble, so this needs to be figured out.
