fpm_module_cache Module

Module-level caching for FPM builds

This module implements a shared cache for compiled Fortran modules (.mod and .o files) that can be reused across different projects. It follows FPM conventions and integrates with the FPM source model.

The cache structure is: ~/.cache/fortran/modules/ / / / module.mod module.o metadata.json

Derived Types

type, public ::  module_cache_t
