Functions

func InstallDirectory

func InstallDirectory()

在主目录下添加目录farmer/ , 包含子目录bin/ etc/ include/ lib/ share/ src/

func Mkdir

func Mkdir(path string) ftype.Error

创建目录, 权限0775.

func Path

func Path(elements ...string) string

将各个元素拼接起来合成路径.

println(Path(HomeDirectory, "go-farmer", "test.txt"))
return

func ReadFile

func ReadFile(filename string) ([]byte, ftype.Error)

读文件.

Example

content, e := ReadFile("/tmp/go-farmer-test.txt")
fassert.CheckError(e, "读文件/tmp/go-farmer-test.txt")
println(string(content))
return

func ReadFileJson

func ReadFileJson(
	filename string,
	data interface{}) ftype.Error

读文件, json格式. @data - 同json.Unmarshal()的参数.

Example

type T struct {
	A string
	B int64
}
var a T
e := ReadFileJson("/tmp/go-farmer-test-json.txt", &a)
fassert.CheckError(e, "读文件/tmp/go-farmer-test-json.txt")

}
var a T
a.A = "hello world"
a.B = 10086
