This module is for the RPC-client. For the core module, refer to https://github.com/bitcoin-s/bitcoin-s-core.
##Prerequisites:
- Scala: http://www.scala-lang.org/
- SBT: http://www.scala-sbt.org/download.html
- Bitcoin-Core: https://bitcoin.org/en/download
##Getting Started
In a terminal, start bitcoin testnet, and enter an SBT console:
tom@tom:~/dev/bitcoin-s-rpc-client$ bitcoind -testnet -daemon
Bitcoin server starting
tom@tom:~/dev/bitcoin-s-rpc-client$ sbt console

import org.bitcoins.rpc.ScalaRPCClient
scala> val test = new ScalaRPCClient("bitcoin-cli","-testnet")
test: org.bitcoins.rpc.ScalaRPCClient = org.bitcoins.rpc.ScalaRPCClient@32e933d8We can use the sendCommand function to make RPC calls in the SBT console:
scala> test.sendCommand("getblockcount")
res0: String =
"808463
"
scala> test.sendCommand("getblockchaininfo")
res1: String =
"{
"chain" : "test",
"blocks" : 808464,
"headers" : 808464,
"bestblockhash" : "0000000000d42f628e1e3b9754c0b245a08a9998378c7d40ee31838a347531f7",

Bitcoin-S has some RPCs that can be called with functions. Some return a single value:
scala> test.getBlockCount
res2: Int = 808463Others return interactive JSON objects:
scala> test.getBlockChainInfo
res3: org.bitcoins.rpc.bitcoincore.blockchain.BlockchainInfo = BlockChainInfoImpl(test,808464,808464,000000000041d1047d0f2d8415c518baf367574d9d2583e491873c1bdf6f5a79,1.0,1.00000230,00000000000000000000000000000000000000000000000a745080437a62ecc9)
scala> test.getBlockChainInfo.chain
res4: String = test
scala> test.getBlockChainInfo.chainWork
res5: String = 00000000000000000000000000000000000000000000000a745080437a62ecc9
scala> test.getBlockChainInfo.bestBlockHash
res6: String = 0000000000d42f628e1e3b9754c0b245a08a9998378c7d40ee31838a347531f7
