go get github.com/newdag/config
Given a sample configuration file:
#test.cfg: address = 0x1234567890
[server]
cacheSize=2232
autoStart = false
[node]
node_addr: 192.168.1.111
host: www.example.com
protocol: http://
url: %(protocol)s%(host)s
//---------------------------------------------
To read this configuration file, do:
cfg, err := config.ReadFile("test.cfg")
s, _ := cfg.GetString("node", "url")
s1 = cfg.GetValue("node", "url", "").(string)
// result is： http://www.example.com
//注意GetValue后做类型转换.(type)一定要和defaultValue对应，否则就会报错
value1 := cfg.GetValue("", "address", "").(string)
fmt.Println(value1)
// result is： 0x1234567890
value2 := cfg.GetValue("server", "XXX", "nothing").(string)
fmt.Println(value2)
// result is： nothing
value3 := cfg.GetValue("server", "cacheSize", 0).(int)
fmt.Println(value3)
// result is： 2232
Note the support for unfolding variables (such as %(base-url)s), which are read
from the special (reserved) section name [DEFAULT].
Note that sections, options and values are all case-sensitive.
