This works only on macOS

• mattn/gitter-cli
• julienXX/terminal-notifier

• start daemon: ./gitter-notifier.sh <room_name>

terminal-notifier can be installed via homebrew

$ brew install terminal-notifier

gitter-cli can be installed via go

$ go get github.com/mattn/gitter-cli

For now I don't pripair any installation. I'll make homebrew formula later.

Please clone this and execute script directly

$ git clone https://github.com/Cj-bc/gitter-notifier
$ cd gitter-notifier
$ ./gitter-notifier.sh <room_name>
