This application does work, but has many known bugs and is not under active development.

You can't go get this package; I use gb instead. If you already have that, skip the first line.

go get github.com/constabulary/gb/...
git clone http://github.com/mhoc/river
cd river
gb build
./bin/main (wsurl)

You can, of course, move and rename that main binary into your $PATH.

I've pre-built an OSX binary for you if you prefer. Check under "releases".

river (wsurl)

You can exit river using C-x.

/json: Enables and disables easy json parsing. Sending, say, id:5 name:michael will expand to {"id":5,"name":"michael"}. Its pretty basic right now. No nested objects or arrays.
