  • #199: Fix broken link for LLVM flang

  • #205: Add more electronic structure and atomistic simulation packages

  • #206: Add books to learning section

  • #208: Fix package information

Ongoing work:

  • #201 (WIP): Internationalization for fortran-lang

  • #207 (WIP): Correct subtitle of setting up your os

Let us know if you have any suggestions for the website and its content. We welcome any new contributors to the website and the tutorials page in particular - see the contributor guide for how to get started.

Fortran Standard Library

Here’s what’s new in stdlib:

  • #271: Probability Distribution and Statistical Functions–PRNG Module

  • #304: Add supported compilers MinGW 8, 9, 10

  • #310: Extend stdlib_ascii module for handling character variables

  • #324: Install setuptools for MinGW builds

Work in progress:

  • #189 (WIP): Initial implementation of sparse matrices.

  • #272 (WIP), #273 (WIP), #276 (WIP), #278 (WIP): Implementation of the stdlib_stats_distribution modules. It provides probability distribution and statistical functions.

  • #311 (WIP): Implementation of a module for handling lists of strings

  • #320 (WIP): Implement non-fancy functional string type

  • #313 (WIP): Legendre polynomials and Gaussian quadrature

Please help improve stdlib by testing and reviewing these pull requests!

The candidate for file system operations to be included in stdlib is being developed by @MarDiehl and @arjenmarkus in this repository. Please try it out and let us know how it works, if there are any issues, or if the API can be improved.

Fortran Package Manager

Here’s what’s new in fpm:

  • #316: Update subcommand “new” to reflect the addition of support for the example/ directory

  • #345: Fpm backend with dynamic openmp scheduling

  • #346: Include root dir in path to default example setup

  • #349: Suggest to move the fpm version in the boostrapping process

  • #372: Unify release mode calling convention

Work in progress:

  • First beta release (WIP): First feature-complete release of the Fortran implementation.

  • #230, #261 (WIP): Document the specification of the fpm CLI.

  • #352 (WIP): Hacky fix for the help test

  • #357 (WIP): Install script for Fortran fpm

  • #364 (WIP): Plugin alpha version

  • #369 (WIP): Separate build targets from model structure

  • #370 (WIP): Update run subcommand

fpm is still in early development and we need as much help as we can get. Here’s how you can help today:

  • Use it and let us know what you think! Read the fpm packaging guide to learn how to build your package with fpm, and the manifest reference to learn what are all the things that you can specify in the fpm.toml file.

  • Browse existing fpm packages on the fortran-lang website

  • Browse the open issues and see if you can help implement any fixes or features.

  • Adapt your Fortran package for fpm and submit it to the Registry.

  • Improve the documentation.

The short-term goal of fpm is to make development and installation of Fortran packages with dependencies easier. Its long term goal is to build a rich and decentralized ecosystem of Fortran packages and create a healthy environment in which new open source Fortran projects are created and published with ease.




  • We had our 9th Fortran Monthly call on February 25. You can watch the recording below:

  • This year Fortran-lang applied as a mentor organization for Google Summer of Code. Accepted mentor organizations will be announced on March 9. If you’re a student, or know students who are eligible to participate, and you’d like to help build the Fortran ecosystem please reach out and let us know.

  • The 223rd meeting of the US Fortran Standards Committee is held virtually from February 22 to March 2 (Monday and Tuesday only). Main topics of dicussion are the planned changes for the Fortran 202X revision of the Standard:

    • List of all submitted papers

    • Summary of which papers were discussed each day and voting results

    If you have ideas for new improvements to the language, please propose them here.

As usual, subscribe to the mailing list and/or join the Discourse to stay tuned with the future meetings.
