Dear all, It’s again time to organize our next monthly call which will be in the week of January 18-22; please see the following doodle poll to mark your availability: ### [Doodle: Fortran Monthly Call: January 2021](https://doodle.com/poll/4bse6ku2z9vz5r3y) The final time slot will be selected and announced on the evening (European time) of Sunday January 17. Please complete the poll before then. If there are specific topics or issues you would like to raise, even if you are unable to attend the call, please post them in the thread here. As usual, we will record this call and make it available online. All the best, Jeremie ---

A recent message in the GCC mailing list made me think whether the “Google Summer of Code” might be a means to get more things done in a shorter interval and engage moer people in the development of fpm or the standard library. Just a thought, nothing concrete ;). And I do not even know what qualifications you need to have to participate in the programme (what kind of organisation for instance). ---

I really like the idea, both stdlib and fpm have suitable topics for larger, self-contained projects. Since we claim/know Fortran is an easy to use and learn language, we can prove it here. Certainly, it would be a nice experience for us as well to reduce barriers for students/developers trying to engage in Fortran development. Seems like the organization registration will open on 29th January, so there is plenty of time to discuss, see > **[Google Summer of Code](https://summerofcode.withgoogle.com/)** Has anyone already made experience with Google Summer of Code before? I saw two GSoC projects at SymPy mentored by @certik. ---

If @hsnyder can join, it’d be great to review and discuss the [Gaussian quadrature API for stdlib](https://github.com/fortran-lang/stdlib/issues/277). (I won’t be able to join today, sorry!) ---

I’m afraid I won’t be able to today either - have some work deadlines to hit. Sorry! Edit: that said, if you want to briefly discuss it on the call, and post the community feedback on github, I would appreciate that. To summarize, the currently proposed API: Gauss-legendre and gauss-legendre-lobatto points and weights, real64 only: ```auto subroutine gauss_legendre(x,w,interval) real(real64), intent(out) :: x(:), w(:) ! pts, wghts real(real64), optional, intent(in) :: interval(2) ! This defaults to [-1.0_real64, 1.0_real64] end subroutine subroutine gauss_legendre_lobatto(x,w,interval) real(real64), intent(out) :: x(:), w(:) ! pts, wghts real(real64), optional, intent(in) :: interval(2) ! This defaults to [-1.0_real64, 1.0_real64] end subroutine ``` Plus, Legendre polynomials and first derivative thereof (real32 and real64 would be offered): ```auto elemental real function legendre (N, x) integer :: N ! which legendre polynomial? real :: x ! the point to evaluate at end function elemental real function dlegendre (N, x) integer :: N ! which legendre polynomial? real :: x ! the point to evaluate at end function ``` And maybe this as well, for returning all legendre polys up to and including N (real32 and real64 would be offered): ```auto subroutine legendre_upto (N, x, p) integer, intent(in) :: N ! highest legendre polynomial degree real, intent(in) :: x ! the point to evaluate real, intent(out) :: p(0:N) end subroutine ``` ---

Thank you all for joining the meeting. @argenti Thank you for joining the call and your proposition in the chat. I only saw it after the call. Sorry to have missed it. I think your proposition would be appropriate for stdlib. Could you open an issue on Github (stdlib project) to discuss your proposition there, please? ---

A few of my notes from the meeting: - @awvwgk has made a number of pull requests to make stdlib usable as a CMake package. It is now the time to start versioning the library. - The GCC developers are also applying for GSoC and have a list of Fortran topics available at [SummerOfCode - GCC Wiki](https://gcc.gnu.org/wiki/SummerOfCode). We can use our channels (Twitter account, Fortran newsletter) to advertise it (they need students interested in Fortran compiler development). - The SimplyFortran IDE is now shipping with an [stdlib package](https://packages.simplyfortran.com/package/92.html) (Thanks to @Arjen for the link). I think this is a great development, which could bring stdlib closer to many. - The [stdlib-os](https://github.com/MarDiehl/stdlib_os) module is currently not integratable with fpm, however it could be already put to good use within fpm. - The [string list](https://github.com/fortran-lang/stdlib/pull/269) derived type proposed by @Arjen could be used to return the names of files and directories present in a given directory in the stdlib-os module. ---
