User Guide¶

Use the section for your native language, then continue with the shared build workflow that matches how you run PRIK.

Fortran¶

• Data Types — Fortran types and exact NumPy dtypes
• Arrays — rank, shape, layout, strides, and mutation
• Strings — scalar text, mutable storage, and string arrays
• Functions and Subroutines
• Modules, Optional Arguments, and Generic Interfaces
• Derived Types
• Allocatables, Pointers, and Memory Management
• Callbacks, Enumerations, Raw Addresses, and Error Handling

C¶

• Overview — choose the source-driven or authored-contract path
• Functions and Scalars — build a function and shape its Python call surface
• Pointers, Arrays, and Strings — assign precise Python meanings to pointer parameters
• Outputs and Errors — return output storage and project native failures
• Symbols, Headers, and Dependencies — overloads, headers, libraries, and API inspection

Build Workflows¶

• Building the Shared Library — compilers, source sets, output placement, Makefiles, and CMake
• CMake Builds — integrate PRIK into an existing CMake project or generate a standalone one
• IPython and Jupyter Notebooks — compile Fortran and C cells and edit semantic contracts interactively

The .pyi Format defines the shared semantic contract language. Use the language feature matrix to check current Fortran and C coverage.
