dgraph cli client

This is a dgraph cli client that will execute commands on dgraph. I needed an app to execute queries and mutations on a production server that cannot run ratel or anything else on it.

It uses DGRAPH_CONNECTION environment variable to read the connection details to the instance of dgraph. If it is not provided,. it will try and connect to localhost.

The cli has the following features:

dg exec -query '{ user(func: eq(type, "user")) { uid name } }'
dg exec -f -query '{ user(func: eq(type, "user")) { uid name } }' (beautify JSON output)
dg exec -schema "jobTitle: string @index(exact) . "
dg exec -mutate '<0xa4> <jobTitle> "job1" .'
dg exec -delete "<0xa4> * * ."

You can also use a yaml file with schema definitions or mutations:

dg yaml -file "/users/usera/changes.yaml"

the format of the yaml files is :

description : "schema changes for banner"

schema :
  - "jobTitle: string @index(exact) . "
  - "jobParticipant: uid @reverse . "

mutations :
  - _:job <jobTitle> "job1" .
  - _:job <jobParticipant> <0x11> .
  - _:job <type> "job" .

deletes :
  - "<0x11> * * . "
  - "<0x3f30> <mediaArtist> * . "
