How to List all Standard Packages in Go
Created
Modified
Using packages
go install
Use the following command to download the repository to the local file system.
install
go get golang.org/x/tools/go/packages
go install golang.org/x/tools/go/packages@latest
Note that since Go 1.17 installing packages with go get is deprecated:
packages Usage
Package packages loads Go packages for inspection and analysis.
For example,
package main
import (
"fmt"
"golang.org/x/tools/go/packages"
)
func main() {
pkgs, err := packages.Load(nil, "std")
if err != nil {
panic(err)
}
fmt.Println(pkgs)
}

Using exec.Command Function
Use the go list std command to list the standard packages. The special import path std expands to all packages in the standard Go library.
See the following example:
package main
import (
"fmt"
"os/exec"
"strings"
)
func main() {
cmd := exec.Command("go", "list", "std")
o, err := cmd.Output()
if err != nil {
panic(err)
}
pkgs := strings.Fields(string(o))
fmt.Println(pkgs)
}
