List of popular open source Fortran projects

[certik]

In order to more easily judge how Fortran developers actually use Fortran in real production codes (this can be useful for issues like #25), let's maintain a list of popular open source Fortran projects here, sorted by the number of stars at GitHub (in parentheses).

The list was moved to a Wiki:

https://github.com/fortran-lang/stdlib/wiki/List-of-popular-open-source-Fortran-projects

[certik]

Everybody, can you please help find Fortran projects at GitHub that have more than let's say ~30 stars, so that we have a complete list above? I will update the issue description. GitHub makes this really hard to find for some reason.

[marshallward]

Maybe activate the wiki for this?

Also I feel obliged to link MOM6: https://github.com/NOAA-GFDL/MOM6

(The GFDL framework almost hits the threshold at 29: https://github.com/NOAA-GFDL/FMS)

Here are mine:

• json-fortran [178]
• bspline-fortran [82]
• pyplot-fortran [65]
• Fortran-Astrodynamics-Toolkit [65]
• slsqp [30]
• fortran-csv-module [30]

[certik]

I am moving this to a wiki so that we can all edit. Give me a second.

[milancurcic]

I added a few more of mine (neural-fortran, tsunami, tcp-client-server).

Awesome Fortran is a useful list.

Done: https://github.com/fortran-lang/stdlib/wiki/List-of-popular-open-source-Fortran-projects

@marshallward, @jacobwilliams would you mind putting the codes you mentioned into the wiki please?

[certik]

@marshallward We can lower the threshold. I set it at 30 to make the number of codes manageable, but it looks like there is not that many. We can lower it to 25 or 20.

[certik]

@milancurcic there is lots of Fortran codes out there, but if it is not on GitHub, not even a GitHub mirror (like I've done for LFortran), then I feel those codes are pretty much not developed anymore (or not open source). So restricting to only codes at GitHub I think is a proxy for codes that are "modern enough". (There are some codes however that didn't get a single commit in 5 or more years...)

[marshallward]

I couldn't see a way to edit the wiki, might need a permissions change?

[certik]

@marshallward try again, I made the wiki editable by any GitHub user.

[marshallward]

Thanks, working now.

[certik]

I found a nice list here: https://github.com/topics/fortran, again, not all the codes, but quite a few listed above are there plus more. Let's keep the number of stars at 29 or more, and we'll see how many codes we get.

[certik]

I extracted all projects that I was able to find so far. The github page https://github.com/topics/fortran as well as the various searches do not actually show all the projects for some reason, but I think the list is starting to get quite accurate. Here is some statistics:

# of contributors, # of projects
1 - 10
2 - 5
3 - 5
4 - 4
5 - 5
6 - 2
7 - 1
8 - 2
9 - 0
10 - 0
...
13 - 1
14 - 1
22 - 1
23 - 1
25 - 1
27 - 1
30 - 1
41 - 2
43 - 1
46 - 1

Total: 45

In particular, if we require at least 3 contributors to exclude one man projects, then there are only ~ 30 projects with at least 29 stars. And there is only 11 projects with more than 8 contributors.

Don't know if its still actively maintained but Fortranwiki (fortranwiki.org/fortran/show/HomePage)
used to have some lists of codes/projects broken down by application type etc. I would guess some of the links though are stale or broken.
