"Unable to create file" error when using ISO week "gggg-[W]WW"

[mturilin]

• I set up my weekly file pattern to "gggg-[W]WW"
• When I click on "Open this week" button I see an error "Unable to create file"

Root cause:
I dug through the source code. The problem that when the app calculates the beginning of the week we should use:

• ISO week: moment.startOf("isoWeek")
• Normal week: moment.startOf("week")

Test case:

> window.moment("2021-W47", "gggg-[W]WW", true).startOf("week").format("gggg-[W]WW");
< "2021-W46" // ERROR: expected "2021-W47"

> window.moment("2021-W47", "gggg-[W]WW", true).startOf("isoWeek").format("gggg-[W]WW");
< "2021-W47" // SUCCESS - this is what we should use for ISO weeks

> window.moment("2021-W47", "gggg-[W]ww", true).startOf("week").format("gggg-[W]ww");
< "2021-W47" // Non-ISO week works fine

Yeah, this plugin admittedly could handle ISO dates better. Thanks for the report and the debugging!

A workaround for now is to change your locale using the Calendar plugin. In the Calendar plugin settings, there's a dropdown to change the locale to en-GB which will get respected by Periodic Notes too. Then can keep the format as gggg-[W]ww which will be the same as the ISO week numbers.

But I'll work on getting a real fix in soon!

@mturilin shouldn't you use GGGG-[W]WW for complete ISO format? (there may be a difference at the end of the year)

Anyway I have the same problem with GGGG-[W]WW this week. It should be 2021-W52. it's correctly reported here

But when I create the I get the Unable to create the file along with

Once the files is created, it works fine.

Btw using GGGG-[w]WW instead (or without the square brackets GGGG-WW) does work, but such format generates 2021-w52 (or without w) for the current week, which is also wrong.
