FortranPatterns

Implementation of popular design patterns in Fortran. This is intended to facilitate the community using Fortran for computationally expensive tasks. The main philosophy here is to make these patterns available for improving the reusability and efficiency of the code.

Tested on: GNU Fortran (GCC) 4.8.

List of patterns:

Creational Patterns

• Abstract Factory
• Builder
• Factory Method
• Prototype
• Singleton

Structural Patterns

• Adapter
• Bridge
• Composite
• Criteria
• Decorator
• Façade
• Flyweight
• Proxy

Behavioral Patterns

• Chain of Responsibility
• Command
• Interpreter
• Iterator
• Mediator
• Memento
• Observer
• State
• Strategy
• Template Method
• Visitor

Build with fortran-lang/fpm

Fortran Package Manager (fpm) is a great package manager and build system for Fortran.
You can build and test using provided fpm.toml:

fpm build --flag "-g"
fpm test --flag "-g" --list     !! test list
fpm test --flag "-g" <test_name, see `fpm.toml` or `test_list`>

Testing

Structural pattern demos such as the façade include small bash helpers to verify their output. For example, run ./structural/facade/run_tests.sh with a Fortran 2008 compiler like gfortran available to confirm the home-theater transcript matches the expected fixture.
