Introduction

Note: Mun & this book are currently under active development, any and all content of this book is not final and may still change.

Mun is an embeddable scripting language designed for developer productivity.

• Ahead of time compilation
  Mun is compiled ahead of time (AOT), as opposed to being interpreted or compiled just in time (JIT). By detecting errors in the code during AOT compilation, an entire class of runtime errors is eliminated. This allows developers to stay within the comfort of their IDE instead of having to switch between the IDE and target application to debug runtime errors.

• Statically typed
  Mun resolves types at compilation time instead of at runtime, resulting in immediate feedback when writing code and opening the door for powerful refactoring tools.

• First class hot-reloading
  Every aspect of Mun is designed with hot reloading in mind. Hot reloading is the process of changing code and resources of a live application, removing the need to start, stop and recompile an application whenever a function or value is changed.

• Performance
  AOT compilation combined with static typing ensure that Mun is compiled to machine code that can be natively executed on any target platform. LLVM is used for compilation and optimization, guaranteeing the best possible performance. Hot reloading does introduce a slight runtime overhead, but it can be disabled for production builds to ensure the best possible runtime performance.

• Cross compilation
  The Mun compiler is able to compile to all supported target platforms from any supported compiler platform.

• Powerful IDE integration
  The Mun language and compiler framework are designed to support source code queries, allowing for powerful IDE integrations such as code completion and refactoring tools.
