Overview

Package repl provides the structs and functions necessary to run REPL for OpenTofu. The REPL allows experimentation of OpenTofu interpolations without having to run a OpenTofu configuration.

• func FormatValue(v cty.Value, indent int) string
• type Session
  • func (s *Session) Handle(line string) (string, bool, tfdiags.Diagnostics)

Functions

func FormatValue

func FormatValue(v cty.Value, indent int) string

FormatValue formats a value in a way that resembles OpenTofu language syntax and uses the type conversion functions where necessary to indicate exactly what type it is given, so that equality test failures can be quickly understood.

Types

type Session

type Session struct {
	// Scope is the evaluation scope where expressions will be evaluated.
	Scope *lang.Scope
}

Session represents the state for a single REPL session.

func (*Session) Handle

func (s *Session) Handle(line string) (string, bool, tfdiags.Diagnostics)

Handle handles a single line of input from the REPL.

This is a stateful operation if a command is given (such as setting a variable). This function should not be called in parallel.

The return value is the output and the error to show.
