Muesli is a Multi Use Embeddable Scripting Language Implementation.

Introduction

It is a scripting language implemented in Go, that has a simple command based TCL like syntax but with rich semantics. Unlice TCL, all values are typed, and many types are supported, not just string values. Additionaly, if so desired, every symbol used in the syntax can be replaced by a key word, leading to a native language programming feel.

Syntax

A Muesli program consists of one or more commands, separated by newlines or periods. Commands can be grouped together in blocks between braces {}. Lists are formed bu placing their contents between brackest []. A single command can be placed in parenthesis (), where the return value of the command will be subsituted.

A command starts with a word, and is followed by any number of arguments, which may be blocks, parenthesis, lists , or values. Like this, the language itself has no control statements, such as if, these are implemented as commands in stead.

Muesly supports several kinds of values, namely:

  • Integers
  • Floats
  • Strings between "double quotes"
  • The booleans !true and !false
  • The nil value !nil
  • Words, which are simple runs of alphanumercial characters starting with a lower case lettter, such as foo
  • Types which are runs of alphanumerical characters starting with an upper case letter. such as Foo
