Go Little Tip

This is a creation in Article, where the information may have evolved or changed.

There are some branches on code.google.com

Some function functions that have not yet been merged into the default

Like Net/websocket.

Http://code.google.com/p/go/source/browse?repo=net#hg%2Fwebsocket

The availability of these libraries is high and is ideal for direct use

Three runs of CMD:

Func (*cmd) Start

Func (*cmd) Run

Func (*cmd) Wait

Start: Run without waiting for process to end

Run: Running wait process end

Wait: waits for process to end

That means run = Start + Wait

The properties in cmd:

Process: Once start is started, process can be used

Processstate: This property can only be used after the process has ended. That must be run or start+wait to use.

String if there are "words, you can use ' to include

Like what:

Jsonstring: = '
{
"Development": {
"Connector": [
{"id": "connector-server-1", "host": "127.0.0.1", "Port": 4050, "Wsport": 3050},
{"id": "connector-server-2", "host": "127.0.0.1", "Port": 4051, "Wsport": 3051},
{"id": "connector-server-3", "host": "127.0.0.1", "Port": 4052, "Wsport": 3052}
],
"Gate": [
{"id": "gate-server-1", "host": "127.0.0.1", "Wsport": 3014}
]
}
}`

Trap for Error interface

Your own definition of the error interface needs to be aware that the interface is two attributes, type and value, when both type and value are nil, it will only be ==nil if the interface inherits from Nil, even if Val is nil, but type is nil type.

For example, this post is asking this question:
