rawjsonrpc

rawjsonrpc is a libary to create a jsonrpc client for every type of stream. It also profides an server and client over tcpip. This is libary is a my first try in ruby to create a gem. Its more a test how gems work but i hope i can help somebody with this lib.

load lib

install libary

gem install rawjsonrpc

include rawjsonrpc in your programm

require 'rawjsonrpc'

Use the TCP client

Create a client to send rpc calls.

client = RawJsonRpc::ClientSocket.new('192.168.2.10', 8080) #creates TCP client
ret = client.request("func1", nil)                 #calles func1 with no para
  			     		       	     #returns result in ret
ret = client.request("func2", 1, 3.0, :test, "om") #calles func2 with 4 paras
ret = client.func3([1, 2, 3, 4])                   #calles func3 with a array
client.notification("noti", 1, "t")                #send notifaction no return value
client.close()

Use the TCP server

Use the gserver to serve data over tcp ip

server = RawJsonRpc::JSONTCPServer.new(8080)
server.add_method("func1", method("do_stuff1")) # adds do_stuff1 as "func1"
server.add_method("foo", method(:bar))          # adds bar as foo
server.add_block("func2"){|a,b, *c|              # adds a block with 2 args
  #do stuff 			 		  # and args as func2
}
server.start
server.join

implement your own jsonclient

Boilerplate Code to create your own client.

class superclient < RawJsonRpc::RawClientJsonRpc 
  def initiailize(*args)
   # init stream
  end

  def send_request(jsonstring)
    #send stream
  end

  def get_response
    #return the response
  end

  def close
    #close resources if needed
  end
end

implement your server

The boilerplattecode to create a new server.

class superserver
  include RawJsonRpc::RawServerJsonRpc

  def initizial(*args)
    #init
  end

  def serve
    #get data from client
    response = execute(jsonstring) #transfers the string and calls function
                                 #return response string or nil if its a notification
    #send response
  end

  def end
    #stuff
  end 
end

known issues

Block arguments can’t be checkt because they are blocks not lamdbas

Your implementations

feel free to contribute your client and servers to the project.

TODO

add examples
add doc for gserver implementation
add a piping server and client
fix block argumentchecks

Contributing to rawjsonrpc

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
