Description:
C++11 (and onwards) library for lazy evaluation

Type: Formula | Latest Version: 8.0.1@0 | Tracked Since: Dec 17, 2025

Category: Developer tools

Tags: c++ library lazy-evaluation header-only ranges

Install: brew install cpp-lazy

About:
cpp-lazy is a header-only C++ library that enables lazy evaluation patterns for sequences and iterators. It provides range-based utilities similar to C++20 ranges but compatible with C++11, allowing efficient processing of large datasets without intermediate storage. The library focuses on performance and ease of integration via a single include.

Key Features:

Header-only design for zero-dependency integration
Lazy evaluation of sequences to optimize memory and compute
C++11 compatibility with modern range and iterator utilities

Use Cases:

Processing large data streams without loading everything into memory
Implementing functional-style pipelines in performance-critical C++ code
Backporting C++20 range features to older C++11/14 projects

Alternatives:

C++20 Ranges – Native standard library but requires C++20; cpp-lazy provides similar functionality for C++11+
Boost.Range – Heavier dependency; cpp-lazy is lightweight and header-only
