Functions

func CopyFile

func CopyFile(dst, src string, mode os.FileMode)

CopyFile copies a file.

func ExpandPackagesNoVendor

func ExpandPackagesNoVendor(patterns []string) []string

ExpandPackagesNoVendor expands a cmd/go import path pattern, skipping vendored packages.

func GOPATH

func GOPATH() string

GOPATH returns the value that the GOPATH environment variable should be set to.

func GoTool

func GoTool(tool string, args ...string) *exec.Cmd

GoTool returns the command that runs a go tool. This uses go from GOROOT instead of PATH so that go commands executed by build use the same version of Go as the 'host' that runs build code. e.g.

/usr/lib/go-1.8/bin/go run build/ci.go ...

runs using go 1.8 and invokes go 1.8 tools from the same GOROOT. This is also important because runtime.Version checks on the host should match the tools that are run.

func MustRun

func MustRun(cmd *exec.Cmd)

MustRun executes the given command and exits the host process for any error.

func MustRunCommand

func MustRunCommand(cmd string, args ...string)

func RunGit
