use random id to name the file

[bangedorrunt]

it'd be great if you could add feature allow us to create file using random id with optional length (prefer 7-8).

this could be done using mktemp XXXXXXX.md for example

note: mktemp in macOS doesn't have --suffix option

[michal-h21]

Good idea. Recent versions of Vim have rand() function, so I've used that and added support. It can be required using:

  let g:zettel_format = "%random"

You can combine it with other formats, of course. The number of characters is configured using

 let g:zettel_random_chars=8 

This is the default value.

Ah, it seems that the srand() function isn't available in Neovim :/

[bangedorrunt]

i hope you could come up with general solution to support neovim when possible 👍

[michal-h21]

I've added the Neovim support, hopefully.

I've added a debugging message to test whether random char generator works. You should get message like

Test random chars: gphxamxi

when you run :messages command.

[bangedorrunt]

i do see the random id

I see, the s:randomchars was not initialized if you set g:zettel_random_chars. I hope it is fixed now.

I've got similar error with ZettalNew command. I deleted vimwiki and vim-zettel plugins and reinstall them again with Vundle. But the issue remains current.

@gleb108 hi, which Vim version do you use? It seems that random numbers are available only from Vim v8.1.2342, or in Neovim. I've seen some hacks for older Vim versions without built-in support for random numbers, but that would mean to support at least three different methods of random number generation. That could lead to quite difficult code to support :/

Ubuntu 20.04.1 LTS is still on Vim 8.1.2269, fwiw, and doesn't have srand either.
