Can't generate weekly journal summary with `:WikiJournalToWeek` about wiki.vim

[lervag]

Great, happy to hear it! :)

Thanks. The problem is most likely due to external calls to the date utilitity. Which system are you on? Linux, BSD, MacOS, ...? What's the output of date --version in a terminal?

[skervim]

Thanks for the prompt answer. The output of date --version is:

My system is Linux (Ubuntu 18.04).

Suddenly it works. Strangely, I cannot reproduce the error anymore, although it occured consistently over the last three days when I tried.

Now, I tested creating a weekly summary of daily entries from a couple of months ago to test whether it only doesn't work for me to create a weekly summary when i'm inside the journal entry of "today". That worked and suddenly it also works from within the journal entry from "today".

Update: I could reproduce the error now. It only occurs when I got to the daily entry with

   `n`     <leader>w<leader>w  |<plug>(wiki-journal)|             [GLOBAL]

and then try :WikiJournalToWeek. It does not occur when I directly open a diary entry via the terminal vim 2020-04-02.md and than try the creation.

[lervag]

Ok, so, the following steps reproduce the issue for you?

1. start Vim/neovim
2. do <leader>w<leader>w to open todays journal entry
3. type :WikiJournalToWeek

[lervag]

Do you get any error messages? If so, could you copy them here?

[skervim]

Yes, those 3 steps reproduce the issue. Then an empty file opens and I just noticed an error message for the first time (the error does not appear immediately but only after clicking the enter key):

Error detected while processing function wiki#link#open:
line    4:                                                                                            
E716: Key not present in Dictionary: open, a:000, l:link)
E116: Invalid arguments for function call
E488: Trailing characters

And I realize that after :WikiJournalToWeek the file name changes from 2020-04-02.md to 2020-04-02’.md .

That does help somewhat, but not enough. It is difficult to debug without actually seeing what is happening on my end. Would you be able to add some debug code?

If you apply the above patch, it should show some relevant output, I think. You might need to do :messages after running the command to see the output. Could you report the output here?

[skervim]

The output after applying the patch is:

date /home/skervim/wiki/journal/2020-04-02
newdate date: invalid date ‘/home/skervim/wiki/journal/2020-04-02’

Next patch:

This should show which parameters are passed to the date utility.

Ah, ok. I think I see now. Can you test latest version?

[skervim]

It works! Thank you very much for the quick and successful fix!
