With BTFSNG, you can mount any .torrent file or magnet link and then use it as any read-only directory in your file tree. The contents of the files will be downloaded on-demand as they are read by applications. Tools like ls, cat and cp works as expected. Applications like vlc and mplayer can also work without changes.

This is a heavily refactored version of BTFS.

• the build system is replaced with Meson
• most of the code is moved into classes
• global variables and static functions mostly removed
• optimizations made:
  • replaced maps with unordered maps
  • implemented more precise pieces triggers
  • the requested piece gets max priority, up to 15 pieces after it get slightly less priority
  • more precise locks (per torrent and per read request) to allow for better parallelism (might be too optimistic and cause race conditions instead so need testing)
• pthread function calls are replaced with C++11 synchronization primitives and threads.
• added verbose logging via easylogging++
• multitorrent support (no name collision resolving)
• option to set the downloaded files path to resume downloading/seeding later. Original BTFS creates temporary directories with random names so seeding is impossible after unmount even with -k (keep)

$ mkdir mnt
$ btfsng video.torrent http://torrent.site/dl/another.torrent onemore.torrent mnt
$ cd mnt
$ vlc video.mp4

To unmount and shutdown:

$ fusermount -u mnt

• libtorrent ("libtorrent-rasterbar8" in Ubuntu 16.04)
• libcurl ("libcurl3" in Ubuntu 16.04)
• boost-system, boost-filesystem ("libboost-filesystem-dev" and "libboost-system-dev" in Ubuntu 16.04)
