Variables

var (

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

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

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

	// 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.

Global build parameters (used during package load)

	GO386    = objabi.GO386
	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.
