func GetConfigDir ¶

func GetConfigDir() (string, error)

GetConfigDir returns the sprout configuration directory path.

func GetEnv ¶

func GetEnv(suffix string) string

GetEnv returns the value of os.Getenv("SPROUT_"+suffix), or "" if unset.

func GetEnvSimple ¶

func GetEnvSimple(suffix string) string

GetEnvSimple checks SPROUT_* for a variable name suffix. E.g., GetEnvSimple("CONFIG") checks SPROUT_CONFIG.

func HasPrefix ¶

func HasPrefix(name string) bool

HasPrefix checks if an env var name starts with SPROUT_.

func LookupEnv ¶

func LookupEnv(suffix string) (string, bool)

LookupEnv checks SPROUT_*. Returns the value and whether it was found.

func ResolveColorPreference ¶

func ResolveColorPreference(want bool) bool

ResolveColorPreference applies the no-color.org environment overrides to a caller-supplied preference. SP-048-4a.

Precedence (no-color.org-mandated):

• NO_COLOR set to any non-empty value → colors OFF (always wins)
• FORCE_COLOR set to any non-empty value → colors ON (unless NO_COLOR)
• otherwise → caller's want value

Lives in pkg/envutil because pkg/console depends on pkg/configuration (transitively pkg/utils) so pkg/utils can't import pkg/console without creating a cycle. pkg/envutil is the existing zero-dependency leaf used for env-var helpers.

func SetEnv ¶

func SetEnv(suffix, value string) error

SetEnv sets the SPROUT_* version of an env var.

func UnsetEnv ¶

func UnsetEnv(suffix string)

UnsetEnv removes the SPROUT_* version of an env var.
