cmd包分析
cmd下面总共有13个子包，除了util包之外，每个子包都有一个主函数,每个主函数的init方法中都定义了该主函数支持的命令，如
geth包下面的：
func init() {
// Initialize the CLI app and start Geth
app.Action = geth
app.HideVersion = true // we have a command to print the version
app.Copyright = "Copyright 2013-2017 The go-ethereum Authors"
app.Commands = []cli.Command{
// See chaincmd.go:
initCommand,
importCommand,
exportCommand,
copydbCommand,
removedbCommand,
dumpCommand,
// See monitorcmd.go:
monitorCommand,
// See accountcmd.go:
accountCommand,
walletCommand,
// See consolecmd.go:
consoleCommand,
attachCommand,
javascriptCommand,
// See misccmd.go:
makecacheCommand,
makedagCommand,
versionCommand,
bugCommand,
licenseCommand,
// See config.go
dumpConfigCommand,
}
sort.Sort(cli.CommandsByName(app.Commands))
}
再单独分析initCommand:
initCommand = cli.Command{
Action: utils.MigrateFlags(initGenesis),
Name: "init",
Usage: "Bootstrap and initialize a new genesis block",
ArgsUsage: "<genesisPath>",
Flags: []cli.Flag{
utils.DataDirFlag,
utils.LightModeFlag,
},
Category: "BLOCKCHAIN COMMANDS",
Description: `
The init command initializes a new genesis block and definition for the network.
This is a destructive action and changes the network in which you will be
participating.
其中Name是对应命令的指令，action是调用该指令去完成的动作，usage表示用途,arguUsage显示该命令后面跟的参数个数以及每个参数的意义,
该init方法其实就是去初始化创世块,flags代表的是这个子命令额外可以执行的命令,如改init命令可以携带两个参数，点进去utils.DataDirFlag可以看到：
// General settings
DataDirFlag = DirectoryFlag{
Name: "datadir",
Usage: "Data directory for the databases and keystore",
Value: DirectoryString{node.DefaultDataDir()},
}
-
可以用 --datadir [dir]来指定数据库的路径，如果没有指定由于该参数有value所以会启用默认的路径，也是home目录下面的.ethereum.
-
/cmd/wnode/main.go 通过连接其他节点启动
-
/cmd/geth /cmd/swarm 都是定义了很多命令
eth下cmd的rlpdump子包,该包的主要作用从给定文件中转储RLP数据以可读的形式．如果文件名被省略，数据将从stdin中读取
/rlpdump
解码rlp的数据
rlpdump的command的help
Usage: /tmp/___cmd_rlpdump_test [-noascii] [-hex <data>] [filename]
-hex string
dump given hex data
-noascii
don't print ASCII strings readably
-single
print only the first element, discard the rest
Dumps RLP data from the given file in readable form.
If the filename is omitted, data is read from stdin.

cmd包下的p2psim子包的分析, p2psim is a command line client for the HTTP API
首先我们启动对应的main函数,对应的启动参数是--help,来查看该包下所有命令的使用,结果如下:
NAME:
___go_build_main_go__1_ - devp2p simulation command-line client
USAGE:
___go_build_main_go__1_ [global options] command [command options] [arguments...]
VERSION:
0.0.0
COMMANDS:
show show network information
events stream network events
snapshot create a network snapshot to stdout
load load a network snapshot from stdin
node manage simulation nodes
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--api value simulation API URL (default: "http://localhost:8888") [$P2PSIM_API_URL]
--help, -h show help
--version, -v print the version
该子包提供如何下的命令:
p2psim show
p2psim events [--current] [--filter=FILTER]
p2psim snapshot
p2psim load
p2psim node create [--name=NAME] [--services=SERVICES] [--key=KEY]
p2psim node list
p2psim node show <node>
p2psim node start <node>
p2psim node stop <node>
p2psim node connect <node> <peer>
p2psim node disconnect <node> <peer>
p2psim node rpc <node> <method> [<args>] [--subscribe]
要正常使用该子包下的命令，我们需要运行/p2p/simulations/examples/ping-pong.go的主函数来启动一个包含运行简单的节点的仿真网络.
正常启动后,你将看到:
INFO [01-23|11:17:10] using sim adapter
INFO [01-23|11:17:10] starting simulation server on 0.0.0.0:8888...
该服务启动后,提供如下的API,其作用等同于上面的命令,命令调用的实现其实就是调用API,访问的路径前缀就是0.0.0.0:8888:
GET / Get network information
POST /start Start all nodes in the network
POST /stop Stop all nodes in the network
GET /events Stream network events
GET /snapshot Take a network snapshot
POST /snapshot Load a network snapshot
POST /nodes Create a node
GET /nodes Get all nodes in the network
GET /nodes/:nodeid Get node information
POST /nodes/:nodeid/start Start a node
POST /nodes/:nodeid/stop Stop a node
POST /nodes/:nodeid/conn/:peerid Connect two nodes
DELETE /nodes/:nodeid/conn/:peerid Disconnect two nodes
GET /nodes/:nodeid/rpc Make RPC requests to a node via WebSocket
此处不深究API,仿真网络的服务已经起来了,下面开始p2psim包下命令的使用:
