go list performs the action of listing named packages and modules, as well as displaying important build information about files, imports, and dependencies. The invocation stanza for go list is usage: go list [-f format] [-json] [-m] [list flags] [build flags] [packages].

Having access to the data structures that are the main pieces of the build process is powerful. We can use go list to find out a lot about the programs that we are building. For example, take the following simple program, which prints a message and computes a square root for the end user:

package mainimport (    "fmt"    "math")func main() {    fmt.Println("Hello Gophers")    fmt.Println(math.Sqrt(64))}
