The Fortran Standard, as published by the ISO (https://wg5-fortran.org/), does not have a Standard Library. The goal of this project is to provide a community driven and agreed upon de facto "standard" library for Fortran, called a Fortran Standard Library (stdlib). We have a rigorous process how stdlib is developed as documented in our Workflow. stdlib is both a specification and a reference implementation. We are cooperating with the Fortran Standards Committee (e.g., the effort started at the J3 committee repository) and the plan is to continue working with the Committee in the future (such as in the step 5. in the Workflow document), so that if the Committee wants to standardize some feature already available in stdlib, it would base it on stdlib's implementation.

The goal of the Fortran Standard Library is to achieve the following general scope:

• Utilities (containers, strings, files, OS/environment integration, unit testing & assertions, logging, ...)
• Algorithms (searching and sorting, merging, ...)
• Mathematics (linear algebra, sparse matrices, special functions, fast Fourier transform, random numbers, statistics, ordinary differential equations, numerical integration, optimization, ...)

git clone https://github.com/fortran-lang/stdlib cd stdlib

The preprocessor fypp (https://github.com/aradi/fypp) is needed because metaprogramming is used. It can be installed using the command line installer pip.

pip install fypp

cmake -B build cmake --build build cmake --build build --target test

Alternatively, you can build using provided Makefiles:

make -f Makefile.manual 

Documentation is a work in progress (see issue #4) but is currently available at https://stdlib.fortran-lang.org. This includes API documentation automatically generated from static analysis and markup comments in the source files using the FORD tool, as well as a specification document or "spec" for each proposed feature.

Some discussions and prototypes of proposed APIs along with a list of popular open source Fortran projects are available on the wiki.
