Fortranis

Fortranis is a high-level programming language designed as a modern successor to Fortran. It aims to preserve the performance and numerical computing strengths of its predecessor while improving readability, safety, and interoperability with existing code.

Origin and design of Fortranis trace to the mid-2010s, when the Fortranis Consortium released specifications for a language intended for contemporary high-performance computing workloads. The language features modular programming, derived types, strong typing, and an emphasis on array-oriented operations. Optional object-oriented programming is supported, along with a modular namespace system. Compilers are optimized for vectorization, multi-core, and multi-node execution, with parallelism facilitated through interfaces to OpenMP and MPI. Interoperability with legacy Fortran code is a primary goal, supported by a stable interface and a defined ABI to ease calls between Fortranis and Fortran libraries.

Syntax and concepts in Fortranis blend familiar Fortran idioms with modern syntax. The language offers explicit interfaces, derived types, and operator overloading, while maintaining clear separation between data definitions and algorithms. Memory management is designed to be safe by default, with optional manual control for advanced users. The package and module system facilitates reuse and large-scale organization of scientific code, and tooling focuses on build, profiling, and debugging workflows consistent with other modern systems.

Status and reception of Fortranis remain niche and primarily experimental. Adoption centered in academic research groups and some climate, fluid dynamics, and computational physics projects exploring new performance and expressiveness trade-offs. Open-source implementations and reference compilers provide a testbed for evaluation, but a broad ecosystem of libraries and community resources is still developing.
