Overview ¶
Package cfg holds configuration shared by multiple parts of the go command.

const DefaultPkgConfig = `pkg-config`

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

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.
Functions ¶
func DefaultCXX ¶
func GetArchEnv ¶
func GetArchEnv() (key, val string)
GetArchEnv returns the name and setting of the GOARCH-specific architecture environment variable. If the current architecture has no GOARCH-specific variable, GetArchEnv returns empty key and value.
func Getenv ¶
Getenv gets the value for the configuration key. It consults the operating system environment and then the go/env file. If Getenv is called for a key that cannot be set in the go/env file (for example GODEBUG), it panics. This ensures that CanGetenv is accurate, so that 'go env -w' stays in sync with what Getenv can retrieve.
