func EnvMap ¶ added in v3.3.0

func EnvMap(replaceMap map[string]string) map[string]interface{}

func IsMissingVariableErr ¶ added in v3.7.11

func IsMissingVariableErr(err error) bool

func IsPlaceholder ¶ added in v3.7.11

func IsPlaceholder(s string) bool

IsPlaceholder reports whether s is an internal Argo placeholder value.

func NewPlaceholder ¶ added in v3.7.11

func NewPlaceholder(index int) string

NewPlaceholder generates an internal Argo placeholder string for the given index.

func Replace ¶

func Replace(s string, replaceMap map[string]any, allowUnresolved bool) (string, error)

Replace takes a json-formatted string and performs variable replacement. Values are raw: a nil entry marks an absent optional (a skipped/omitted node's output with no default), and a simple tag resolving to nil is a terminal error regardless of allowUnresolved, which only governs tags whose key is missing entirely.

func ReplaceStrictAny ¶ added in v3.7.16

func ReplaceStrictAny(s string, replaceMap map[string]any, strictPrefixes []string) (string, error)

ReplaceStrictAny behaves like Replace but enforces that tags starting with any of strictPrefixes MUST be resolved, even if allowUnresolved behavior is otherwise active (implicit). It takes raw values, preserving nil entries so that expression tags can distinguish an absent (nil) value from an empty string (e.g. via `??`). A simple tag resolving to a nil value is a terminal error (not a missing-variable error): an absent optional must be handled by a producer default, a consumer input default (dropping the argument before substitution), or an expression fallback.

func ResolveVar ¶

func ResolveVar(s string, m map[string]interface{}) (interface{}, error)

func ToAnyMap ¶ added in v3.7.16

func ToAnyMap(m map[string]string) map[string]any

ToAnyMap widens a string map for use with Replace. Callers that track absent optionals (skipped/omitted node outputs) build a map[string]any directly so nil entries survive.

func Validate ¶

func Validate(s string, validator func(tag string) error) error
