[ 3] bitmalloc : it’s essentially the same as what is in the readme
[ 4] bitmalloc : # Make Alice follow Bob, and give them names.
$ curl localhost:80/query -X POST -d $'mutation { set {<alice> <follows> <bob> . \n <alice> <name> "Alice" . \n <bob> <name> "Bob" . }}'
# Now run a query to find all the people Alice follows 2 levels deep. The query would only result in 1 connection, Alice to Bob.
$ curl localhost:80/query -X POST -d '{me(_xid_: alice) { name _xid_ follows { name _xid_ follows {name _xid_ } } }}'
# Make Bob follow Greg.
$ curl localhost:80/query -X POST -d $'mutation { set {<bob> <follows> <greg> . \n <greg> <name> "Greg" .}}'
# The same query as above now would now show 2 connections, one from Alice to Bob, another from Bob to Greg.
$ curl localhost:80/query -X POST -d '{me(_xid_: alice) { name _xid_ follows { name _xid_ follows {name _xid_ } } }}’```
[ 5] ashwin95r : Umm I guess the mutation didn't happen
[ 6] ashwin95r : @mrjn, is the flag for mutation off by default?
[ 7] nii236 : I know we established that you can only go S -> O but nto O -> S
[ 8] bitmalloc : this is the log entry on the server for the mutation request:

[ 9] :
[10] pawan : hey change the port to `8080`
[11] :
[12] pawan : Or are you running it using Docker?
[13] bitmalloc : port 8080 -> 80 in docker
[14] mrjn : @nii236: Yeah. We won't be doing that. If people want it, they'll have to create a predicate in the opposite direction. Freebase data has that -- predicates going both directions.
[15] nii236 : no worries, I’ve just finished manually adding reverse preds
[16] pawan : I see that you built this from master, could you try this with `docker pull dgraph/dgraph:latest` @bitmalloc?
[17] mrjn : Did you add the data first, via mutations? @bitmalloc
[18] bitmalloc : yeah, I did: $ curl localhost:80/query -X POST -d $'mutation { set {<alice> <follows> <bob> . \n <alice> <name> "Alice" . \n <bob> <name> "Bob" . }}’ for the mutation, just like it’s in the README
[19] mrjn : Can you post the output from that as well?
[20] mrjn : In fact, we might have to dig deeper here, so maybe a discuss post is better suited. @pawan wisemonk magic?

No results
When running this, I get this error:
2016/06/22 15:29:22 Error while retrieving subgraph root: Expected some name. Got: lex.Item [7] "}"
Looks like a lexing issue.
