ETLCPP/etl

ETL is a C++ template library that provides STL-like containers and algorithms optimized for embedded systems and applications with limited resources.

The library addresses the challenge of using modern C++ abstractions in resource-constrained environments where dynamic memory allocation is problematic or unavailable. ETL offers fixed-size containers, algorithms, and utilities that mirror the interface of the C++ Standard Library but operate without heap allocation. This approach allows embedded developers to write familiar, type-safe code while maintaining predictable memory usage and performance characteristics critical to embedded applications.

Developers should choose ETL when working on embedded systems, real-time applications, or any project where dynamic memory must be avoided or minimized. The library suits projects that benefit from STL-like interfaces but cannot rely on the standard library's dynamic allocation model. It is particularly valuable for bare-metal programming, microcontroller applications, and systems where memory is fixed at compile time. The tool provides drop-in replacements for common STL containers like vectors, lists, and queues, but with predetermined maximum sizes specified as template parameters.

The project maintains steady development activity with regular commits addressing bug fixes, feature additions, and maintenance. The codebase receives ongoing refinement to improve compatibility and expand the range of supported embedded use cases. Documentation and examples are actively maintained to help users understand how to apply the library to their specific embedded scenarios. The project demonstrates consistent engagement with user feedback and evolving embedded systems requirements.
