	BuildLinkshared        bool               // -linkshared flag
	BuildMSan              bool               // -msan flag

	BuildP                 = runtime.NumCPU() // -p flag
	BuildPkgdir            string             // -pkgdir flag
	BuildRace              bool               // -race flag
	BuildToolexec          []string           // -toolexec flag
	BuildToolchainName     string
	BuildToolchainCompiler func() string
	BuildToolchainLinker   func() string
	BuildV                 bool // -v flag
	BuildWork              bool // -work flag
	BuildX                 bool // -x flag

	CmdName string // "build", "install", "list", etc.

	DebugActiongraph string // -debug-actiongraph flag (undocumented, unstable)
)

These are general "build flags" used by build and other commands.

var (
	Goarch    = BuildContext.GOARCH
	Goos      = BuildContext.GOOS
	ExeSuffix string
	Gopath    = filepath.SplitList(BuildContext.GOPATH)

	// ModulesEnabled specifies whether the go command is running
	// in module-aware mode (as opposed to GOPATH mode).
	// It is equal to modload.Enabled, but not all packages can import modload.
	ModulesEnabled bool

	// GoModInGOPATH records whether we've found a go.mod in GOPATH/src
	// in GO111MODULE=auto mode. In that case, we don't use modules
	// but people might expect us to, so 'go get' warns.
	GoModInGOPATH string
)

Global build parameters (used during package load)

	GOMIPS   = objabi.GOMIPS
	GOMIPS64 = objabi.GOMIPS64
)

var CmdEnv []EnvVar

CmdEnv is the new environment for running go tool commands. User binaries (during go test or go run) are run with OrigEnv, not CmdEnv.

var OrigEnv []string

OrigEnv is the original environment of the program at startup.

Types

type EnvVar

type EnvVar struct {
	Name  string
	Value string
}

An EnvVar is an environment variable Name=Value.
