Overview ¶

Package expand implements ${VAR} substitution for commands and env files.

Index ¶

Functions ¶

func OSLookup ¶

func OSLookup(extra map[string]string) func(key string) (string, bool)

OSLookup returns a lookup func backed by the process environment. Keys in extra take precedence over environment variables.

func Vars ¶

func Vars(s string, lookup func(key string) (string, bool)) string

Vars replaces every ${VAR} reference in s using lookup. References that lookup cannot resolve are left untouched, so downstream shells can still expand them. Only the braced form is recognized; a bare $VAR is passed through as-is.

Types ¶
