This repository contains submodules for many Fortran-related projects.
The goal is to have a wide variety of example Fortran codes, as found in the wild.
We plan to use them to analyze Fortran source as found in nature to investigate proposed features for the Fortran 202y (e.g., the proposed preprocessor).
To get all these example Fortran projects
git clone [email protected]:gklimowicz/fortran-examples.git
git submodule update --init
After what seems like forever, you should have some 45GB or so of Fortran example projects.
This works best on a case-sensitive file system. Some projects seem to have a few files with filenames that clash on case-insensitive file systems.
To update after changes have been pushed to fortran-examples
git pull
git submodule update
The numerous top-level directories each contain the source code for a single "project". For projects that come from a super-project (such as "GEOS-ESM"), all the directories begin with the super-project's name as a prefix (such as "GEOS-ESM-AeroApps).
Although this can obscure the Makefile and all-* file lists in the top-level directory, it felt silly to create a src directory and put all the projects underneath that.
Originally, this was to contain the provenance of each of the repositories.
Since this is already saved in .gitmodules for the git-based projects,
this now only contains the origin for sources for non-git projects.
(Note that this may not be a direct link to a .tgz or .zip file, but
may be the page where such a link can be found.)
This file is managed manually.
There are projects mentioned on the fortran-lang.org and Beliavsky pages that don't actually contain Fortran source code that we are interested in (such as only contain .fypp files).
We ignore projects that are in the project-exceptions.txt list.
There are files in projects that have names like Fortran files,
but don't actually contain Fortran source code (e.g., Makefile.f90).
We ignore files that are in the file-exceptions.txt list.
Of all the files found in the projects, files that match these grep patterns
are likely to be Fortran files.
(Those that aren't really Fortran should be in fortran-exceptions.txt.
The Makefile drives the collection of these repositories and the gathering of statistics. Most of them come from the projects listed on fortran-lang.org's projects pages and Beliavsky's Fortran-code-on-GitHub list.
Update Git submodules from remote repos, and create project lists and metrics as described above.
Update each Git project from its origin repository.
Runs git submodule update --remote.
Search for new projects to add. Only looks at fortran-lang.org and github.com/Beliavsky so far.
Do a git pull on each project directory here to bring it up to date
with respect to its home repository.
Print a couple lines of interesting statistics about the repository as a whole.
File names that begin with "all-" contain aggregated lists and metrics for the sample projects.

This is a list of files (produced by bin/find-duplicates) that are not really duplicated projects. They are either completely different projects, modernizations, or some other variation on a theme.
