Functions

func ExpressionEvaluateAsIter

func ExpressionEvaluateAsIter(ctx context.Context, env Env, expressionString string) (any, error)

ExpressionEvaluateAsIter evaluates the expression and returns an iterator sequence (iter.Seq[any] for slices, iter.Seq2[string, any] for maps) if the result is iterable. Otherwise, it returns an error.

func ExpressionEvaluateAsIterWithTracking

func ExpressionEvaluateAsIterWithTracking(ctx context.Context, env Env, expressionString string, tracker *tracking.VariableTracker) (any, error)

ExpressionEvaluateAsIterWithTracking evaluates an iterable expression with variable access tracking

func ExpressionEvaluteAsArray

func ExpressionEvaluteAsArray(ctx context.Context, env Env, expressionString string) ([]any, error)

func ExpressionEvaluteAsArrayWithTracking

func ExpressionEvaluteAsArrayWithTracking(ctx context.Context, env Env, expressionString string, tracker *tracking.VariableTracker) ([]any, error)

ExpressionEvaluteAsArrayWithTracking evaluates an array expression with variable access tracking

func ExpressionEvaluteAsBool

func ExpressionEvaluteAsBool(ctx context.Context, env Env, expressionString string) (bool, error)

func ExpressionEvaluteAsBoolWithTracking

func ExpressionEvaluteAsBoolWithTracking(ctx context.Context, env Env, expressionString string, tracker *tracking.VariableTracker) (bool, error)

ExpressionEvaluteAsBoolWithTracking evaluates a boolean expression with variable access tracking

func NormalizeExpression

func NormalizeExpression(ctx context.Context, expressionString string, varsystem varsystem.VarMap) (string, error)

Types

type Env

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

func NewEnv

func NewEnv(varMap map[string]any) Env

func NewEnvFromStruct

func NewEnvFromStruct(s any) (Env, error)

func (Env) GetVarMap

func (e Env) GetVarMap() map[string]any

GetVarMap returns the internal varMap for debugging purposes
