const (

	Sensitive = 1 << iota
)

Functions

func ParseTemplate

func ParseTemplate(text string) (ast.Expr, error)

Types

type EvalError

type EvalError = internal.EvalError

type Evaluator

type Evaluator struct {
	// contains filtered or unexported fields
}

func NewEvaluator

func NewEvaluator(inputsMap value.Value) (*Evaluator, error)

NewEvaluator creates a new Evaluator for input evaluations.

Use the Eval method to evaluate the provided inputs in some text. Sensitive inputs can be marked with the Sensitive mark defined in this package.

func (*Evaluator) Eval

func (e *Evaluator) Eval(text string, expr ast.Expr) (value.Value, error)

Eval evaluates the Evaluator inputs in the given expression.

The evaluated expression is returned as a moa value.Value. Marks, like Sensitive are inferred into that value.

type Input

type Input struct {
	Key   string
	Value value.Value
}

func (Input) MarkSensitive

func (i Input) MarkSensitive() Input

func (Input) Sensitive

func (i Input) Sensitive() bool

type ParseError

type ParseError = internal.ParseError
