Bracket

About

Bracket is a Crystal shard that implements the bracket pattern for safe resource management. This pattern ensures that resources are properly initialized and cleaned up, similar to Python's context managers or Haskell's bracket pattern.

Features

• Guarantees resource cleanup even if an exception occurs
• Type-safe resource handling
• Simple, functional interface
• Works with any resource type

Quick Start

# Add to shard.yml:
dependencies:
  bracket:
    github: wizzardx/bracket

# Basic usage:
require "bracket"

setup = -> { "my resource" }
teardown = ->(resource : String) { puts "Cleaning up #{resource}"; nil }

Bracket.with_resource(setup, teardown) do |resource|
  puts "Using #{resource}"
end
