This initially started as a "meta-package" for Deluge 2.0 dependencies on MacOS, but turned into a full installation of the deluge pip module, including the GUI deluge/deluge-gtk.
Currently, Deluge 2.0 is in beta, but the newest release of the client available for MacOS is 1.x, which is incompatible with 2.0 servers. This tap provides a working (for now?) build for Deluge 2.0 to reduce the troubles with building and linking Deluge's pip module on Mac.
See the official doc page on installation here.
I used this thread on the deluge forums as a reference while working on this.
brew install amar1729/deluge-meta/deluge-meta
Or brew tap amar1729/deluge-meta and then brew install deluge-meta.
brew help, man brew or check Homebrew's documentation.
