Please help improve stdlib by testing and reviewing 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.

Administrador de paquetes de Fortran#

Here’s what’s new in fpm:

  • #507: optimize file listing

  • #511: check name used for package, executable, test, or example

  • #516: initialize allocatable strings before using in a comparison

  • #517: Fix run

  • #522: remove warnings and fix truncated help text

  • #523: Fix compilation error in ifort

Work in progress:

  • #525 (WIP): proposal to close #525 by generating build/.gitignore

  • #527 (WIP): Add objects for handling compiler and archiver

  • #521 (WIP): expand tabs

  • #506 (WIP): Draft: initial implementation of implicit_none

  • #498 (WIP): Draft - Compiler flags profiles

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.
