Dear all,
It’s again time to organise our next monthly call which will be in the week of March 22-26; please see the following doodle poll to mark your availability:

Doodle: Fortran Monthly Call: March 2021

The final time slot will be selected and announced on the evening (European time) of Sunday March 21, 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.

Thank you for organizing these, @jeremie.vandenplas

I have a small proposal for scheduling to help avoid time conflicts.

Problem: Currently, we give ample time for people to indicate availability in Doodle, and then we have a potentially very short notice when a decision about the meeting time is made. Specifically, Doodle is now open for the next 10 days, which is plenty of time. But we will make a meeting time decision on Sunday evening, for a meeting that could in theory be on Monday morning.

When I mark my availability, I look at my calendar for that week and provide all my available time slots. But in the meantime, I’m also scheduling other meetings. So it becomes a game of chance whether I will schedule some meeting at an overlapping time with a Fortran call.

So, I suggest the following:

  • This month, we decide on the meeting time a bit sooner, perhaps at the end of the work week, Friday evening (March 19)
  • In the future, we follow this pattern:
    • Scheduling in Doodle happens during the 1st week of the month
    • Fortran call occurs in the 3rd week of the month (except during events like FortranCon, J3 meetings, and similar, if they occur in the same week).

That way, we will have one week between the meeting time being set, and the meeting itself.

What do you think?


This sounds good to me. A fixed day (e.g, at 8pm (European time) on Tuesdaty of each third week of a month) could be decided too. People could then block this slot in their agenda in advance.We can briefly discuss it during the next call.

For this month, I will follow @milancurcic 's proposition: the final time slot will be selected and announced on the evening (European time) of Friday March 19, instead of March 21.

Note: These calls are open for anyone to join! We have not been very good at communicating this. We are doing these calls to provide a venue for the wide Fortran community to be able to talk. Anyone who is interested is welcome to join.


I want to add some items on the agenda for tomorrow, mostly stdlib related and about documentation:

  1. git workflow/strategy recommendations for fortran-lang repos
    Preferred git strategy · Discussion #358 · fortran-lang/stdlib · GitHub
  2. Updating the style guide / workflow for the stdlib infrastructure (build files, CI workflows, …)
    Summarize build toolchain workflow and implied rules by awvwgk · Pull Request #360 · fortran-lang/stdlib · GitHub
  3. The versioning issue, next steps to actually get started
    Is stdlib versioned? · Issue #292 · fortran-lang/stdlib · GitHub

I realize that the times mentioned earlier might wrong (due to daylight saving time).

Here should be the correct times:

Our next monthly call will be on Wednesday, March 24 at 17:00 UTC .

10:00 - 11:00 PDT (California)
17:00 - 18:00 GMT (London)
18:00 - 19:00 CET (Central Europe)
13:00 - 14:00 EDT

@milancurcic I think the time for the Zoom meeting is wrong. Could you check please?

@jeremie.vandenplas Can you write the meeting time in UTC? That way we’ll be sure, and we’ll be using UTC going forward. Zoom link will work regardless of the time. People just need to know when to show up.

Okay, I see, 17:00 UTC.
