const ToolWindowsExtension = ".exe"
var (
ToolGOOS = runtime.GOOS
ToolGOARCH = runtime.GOARCH
ToolIsWindows = ToolGOOS == "windows"
ToolDir = build.ToolDir
)
Configuration for finding tool binaries.
var Cwd = getwd()
var Go = &Command{ UsageLine: "go", Long: `Go is a tool for managing Go source code.`, }
var Interrupted = make(chan struct{})
Interrupted is closed when the go command receives an interrupt signal.
var SignalTrace os.Signal = syscall.SIGQUIT
SignalTrace is the signal to send to make a Go program crash with a stack trace.
var Usage func()
Usage is the usage-reporting function, filled in by package main but here for reference by other packages.
func AddBuildFlagsNX(flags *flag.FlagSet)
AddBuildFlagsNX adds the -n and -x build flags to the flag set.
func AddKnownFlag(name string)
AddKnownFlag adds name to the list of known flags for use in $GOFLAGS.
func AtExit(f func())
func EnvForDir(dir string, base []string) []string
EnvForDir returns a modified environment suitable for running in the given directory. The environment is the supplied base environment but with an updated $PWD, so that an os.Getwd in the child will be faster.
func Errorf(format string, args ...interface{})
func Exit()
func ExitIfErrors()
func ExpandScanner(err error) error
ExpandScanner expands a scanner.List error into all the errors in the list. The default Error method only shows the first error and does not shorten paths.
func Fatalf(format string, args ...interface{})
func GOFLAGS() []string
GOFLAGS returns the flags from $GOFLAGS. The list can be assumed to contain one string per flag, with each string either beginning with -name or --name.
func GetExitStatus() int
func InitGOFLAGS()
InitGOFLAGS initializes the goflags list from $GOFLAGS. If goflags is already initialized, it does nothing.
func IsTestFile(file string) bool
IsTestFile reports whether the source file is a set of tests and should therefore be excluded from coverage analysis.
func RelPaths(paths []string) []string
RelPaths returns a copy of paths with absolute paths made relative to the current directory if they would be shorter.
func Run(cmdargs ...interface{})
Run runs the command, with stdout and stderr connected to the go command's own stdout and stderr. If the command fails, Run reports the error using Errorf.
func RunStdin(cmdline []string)
RunStdin is like run but connects Stdin.
func SetExitStatus(n int)
func SetFromGOFLAGS(flags flag.FlagSet)
SetFromGOFLAGS sets the flags in the given flag set using settings in $GOFLAGS.
func ShortPath(path string) string
ShortPath returns an absolute or relative name for path, whatever is shorter.
func StartSigHandlers()
StartSigHandlers starts the signal handlers.
func Tool(toolName string) string
Tool returns the path to the named tool (for example, "vet"). If the tool cannot be found, Tool exits the process.
type Command struct {
// Run runs the command.
// The args are the arguments after the command name.
Run func(cmd *Command, args []string)
// UsageLine is the one-line usage message.
// The words between "go" and the first flag or argument in the line are taken to be the command name.
UsageLine string
// Short is the short description shown in the 'go help' output.
Short string
// Long is the long message shown in the 'go help <this-command>' output.
Long string
// Flag is a set of flags specific to this command.
Flag flag.FlagSet
// CustomFlags indicates that the command will do its own
// flag parsing.
CustomFlags bool
// Commands lists the available commands and help topics.
// The order here is the order in which they are printed by 'go help'.
// Note that subcommands are in general best avoided.
Commands []*Command
}
A Command is an implementation of a go command like go build or go fix.
func (c *Command) LongName() string
LongName returns the command's long name: all the words in the usage line between "go" and a flag or argument,
func (c *Command) Name() string
Name returns the command's short name: the last word in the usage line before a flag or argument.
func (c *Command) Runnable() bool
Runnable reports whether the command can be run; otherwise it is a documentation pseudo-command such as importpath.
func (c *Command) Usage()
type StringsFlag []string
A StringsFlag is a command-line flag that interprets its argument as a space-separated list of possibly-quoted strings.
func (v *StringsFlag) Set(s string) error
func (v *StringsFlag) String() string
