go的包管理语句

声明包

PckageClause  = "package" PackageName .
PackageName    = identifier .

导入包(Import declarations )

ImportDecl       = "import" ( ImportSpec | "(" { ImportSpec ";" } ")" ) .
ImportSpec       = [ "." | PackageName ] ImportPath .
ImportPath       = string_lit .

例如:

Import declaration          Local name of Sin

import   "lib/math"         math.Sin
import m "lib/math"         m.Sin
import . "lib/math"         Sin
import _ "lib/math"
