Common Idioms

Introduction

A coding idiom is a solution to a commonly occurring programming problem. In a sense all recipes are idioms, but we use the term here for those recipes that apply to many different tasks. In Scheme many patterns, such as object oriented programming, become idioms as we can express these patterns directly in code using macros.

Recipes

• Evaluate and Test (Recipe)
• The "missing" looping constructs while, repeat-until and for. (Recipe)
• Monadic Programming (Recipe)
• Object Oriented Programming (Recipe)
• Optional arguments (Recipe)
• Returning prematurely from a function (Recipe)
• Sharing state between two functions (Recipe)
• Static Variables for Functions (Recipe)
• Coroutines (Recipe)
• Disallow One-Armed If with a Custom Language (Recipe)
• Accessing Procedure Source Code (Recipe)
• Capturing Location Information (Recipe)
• Serialize Data to File (Recipe)
• Streams (RecipeStub)
• How to provide identifiers that can be mutated with set! directly (Recipe)
• How to Succeed and Fail with Continuations (Recipe)
• Syntax for explicitly uncurrying a MIT-style defined function (Recipe)
