Ruby Blocks Procs Lambdas

What it does

This skill enables an AI agent to understand and utilize Ruby blocks, procs, and lambdas. It allows for passing code snippets as arguments to methods, creating closures, and defining anonymous functions within the Ruby language. The skill facilitates more complex logic and data manipulation through functional programming techniques.

When to use it

• Data Transformation: When needing to apply a custom calculation or filtering rule to a collection of data in a Ruby environment.
• Event Handling: To define short, inline actions triggered by specific events within a Ruby application.
• DSL Creation: For building domain-specific languages where code blocks represent commands or configurations.
• Method Arguments: When needing to pass small chunks of executable Ruby code as arguments to other methods for dynamic behavior.

Key capabilities

• Understanding of Ruby blocks
• Proc creation and usage
• Lambda definition and application
• Passing code snippets as method arguments
• Closure support

Example prompts

• "Write a Ruby block that squares each number in this array: [1, 2, 3, 4]."
• "Create a proc to greet a user by name."
• "Pass a lambda function to the map method to convert strings to uppercase."

Tips & gotchas

• Requires a Ruby runtime environment for execution.
• The agent's understanding is limited to the syntax and common use cases of blocks, procs, and lambdas within Ruby.
