prima
PRIMA is a package for solving general nonlinear optimization problems without using derivatives. It provides the reference implementation for Powell's derivative-free optimization methods, i.e., COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. PRIMA means Reference Implementation for Powell's methods with Modernization and Amelioration, P for Powell.

SciPy: Interested in adopting PRIMA, but little appetite for more Fortran code
Hopefully, the SciPy community can stay open-minded about modern Fortran libraries.
Modern Fortran is quite different from Fortran 77, while being as powerful, if not more.
In addition, there has been a significant community effort on improving and modernising the legacy packages, the ecosystem, and the language itself.
With projects like LFortran (https://lfortran.org/), fpm (https://github.com/fortran-lang/fpm), and stdlib (https://github.com/fortran-lang/stdlib), I believe that Fortran will enjoy prosperity again.

Have you used Fortran for anything other than scientific programming? How is it, and how does it compare to other languages?
They're currently working on a Fortran standard library and it's pretty far along: https://github.com/fortran-lang/stdlib

Why Fortran?
I also like FPM and the ecosystem. In case anyone is just getting started with Fortran, definitely checkout the Fortran Standard Library project:

return value of get_command_argument() and allocatable 1D array
In general, it is necessary to know the length of a string in Fortran before using it. There is no general string with unspecified strength. Some libraries do provide such an object (e.g. Fortran Standard Library, but it is not available in the standard language. To obtain the length of the string in your example, you could use the length option in get_command_argument as integer :: clen character(len=:), allocatable :: string_b call get_command_argument(2, length=clen) allocate(string_b(clen)) string_b = '' call get_command_argument(2, string_b) write(*,*) string_b deallocate(string_b)

A Modern Fortran Scientific Programming Ecosystem
If you need to clear memory in the local scope, you need to deallocate a variable explicitly. Otherwise, all Fortran variables are cleared automatically when they go out of scope. One exception are Fortran pointers (different from C pointers) which are discouraged unless really necessary. We have a discussion for a high-level wrapper for files here: https://github.com/fortran-lang/stdlib/issues/14. So, it's in scope we just haven't gotten far with the design and implementation.

"The State of Fortran" -- accepted for publication in Computing in Science and Engineering
FYPP syntax is ugly, but is the best tool available for now to build the Fortran stdlib. People do not have to use the FYPP version of stdlib. There is also a clean post-processed version of the stdlib completely free of FYPP or any other FPP, which looks great: https://github.com/fortran-lang/stdlib/tree/stdlib-fpm

Cube-root and my dissent into madness
What if we try to evaluate this using standard-compliant Fortran? Interestingly, this is an open issue in the fortran-lang/stdlib project. f90 real(8) function f(x) real(8) :: x f = x**(1d0/3d0) endfunction I know real(8) isn't standard compliant but fixing that for this tiny example would be a headache. Then, compiling with -O3 gets us f_: movsd xmm1, QWORD PTR .LC0[rip] movsd xmm0, QWORD PTR [rdi] jmp pow .LC0: .long 1431655765 .long 1070945621

Learning Functional programming. Which languages to learn.
learn Fortran (supports both FP and OO, but when we say Fortran we think FP mostly). And the best way to learn is contributing. You can checkout their GitHub org (Fortran-lang) and you might be astonished to see that you too can make contributions there. But you should be ready to learn and search things on your own as well. They have a discourse group too, if you get stuck somewhere. Good luck. At the moment of writing this post they have a good first issue (Greatest Common Divisor) on their stdlib repo.

Fortran Web Framework
I recently started learning Fortran for a lark. It reminds me a lot of R, in some respects. It's clearly a very, very good language for doing the parts of one's job that are very math-centric. But it's equally underwhelming as a general purpose programming language.
Largely, I think, due to gaps in the library ecosystem. But there are other challenges. You can see from the install instructions on the linked page, for example, that Fortran still lacks a package manager.
What's interesting, though, is that that's changing. There are currently serious efforts to give it a "standard" library (https://github.com/fortran-lang/stdlib) and package manager (https://github.com/fortran-lang/fpm).
And I've been watching the new LFortran compiler (https://lfortran.org) with extreme interest.
