A Go library implementing C++ STL iterators and algorithms to replace hand-written loops with expressive, reusable code.
Iter is a Go library that implements C++ STL iterators and algorithms, allowing developers to replace hand-written loops with generic, reusable functions. It solves the problem of repetitive and error-prone loop code by providing over 100 algorithms that work with standard Go containers like slices, strings, and lists.
Go developers who write data manipulation logic and seek to improve code expressiveness, correctness, and reuse, especially those familiar with C++ STL or functional programming patterns.
Developers choose Iter for its non-intrusive design that integrates with existing Go containers, its comprehensive algorithm coverage, and performance optimizations that reduce manual implementation effort while enhancing code clarity.
Go implementation of C++ STL iterators and algorithms.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Works seamlessly with standard Go containers like slices, strings, and list.List without requiring new data structures, making it easy to integrate into existing codebases.
Implements over 100 C++ STL algorithms, including complex ones like NthElement and StablePartition, reducing manual implementation errors and saving development time.
Includes subtle optimizations, such as MinmaxElement using pairwise comparisons to significantly reduce comparison operations, improving efficiency in numerical tasks.
Extends algorithms to work with Go channels and I/O writers via adapters like ChanReader and IOWriter, enabling flexible streaming data processing patterns.
Introduces C++ STL iterator terminology and patterns that are not native to Go, increasing cognitive load and potential misuse for developers unfamiliar with these concepts.
Requires helper functions and aliases for readability, as shown in examples, making code more verbose compared to straightforward Go loops for simple operations.
The library is actively being updated for Go generics, leading to API changes and potential breaking issues in current versions, as noted in the README warning.
