(mini.misc) FEATURE: implement setup_mkdir_missing().

[yamhab]

• I have read CONTRIBUTING.md
• I have read CODE_OF_CONDUCT.md

If this PR were to be merged, mini.misc will have the setup_mkdir_missing() function which will automatically create any missing directories needed for saving a file. This is similar to the functionality provided by tidy.nvim. I also made sure it didn't break with netrw URLs, and I wrote it some documentation and tests.

Thanks for the PR!

Sorry, but I don't think this is a good functionality to have. Both in terms of what it provides (performing the check on every BufWrite is costly and redundant as it can be done several times per minute) and adding it to 'mini.misc' (this is a rather trivial autocommand with almost a one line function). I would suggest instead create a file before starting work in it (for example, with 'mini.files' it is very straightforward).

Please, open an issue to discuss a feature first prior to creating a PR. This way it might lead to less time wasted on your side.

Closing as not planned.

I will update 'CHANGELOG.md' to proper mention you for #554, though. Sorry about that.

@echasnovski What if I were to get the autocommand to run only once using the once opts flag for nvim_create_autocmd for better performance? And as for it not being suitable for mini.misc for how short it is, wouldn't the same apply for setup_restore_cursor() because it can mostly just be done with '" in normal mode?

It won't work with a simple once as it should create the autocommand on every BufCreate event. Besides, it doesn't address the fact that I don't really want to enable this kind of workflow.

And as for it not being suitable for mini.misc for how short it is, wouldn't the same apply for setup_restore_cursor() because it can mostly just be done with '" in normal mode?

setup_restore_cursor() does a bit more than that (checks if cursor was already placed, checks for proper " register, opens folds, centers window) and does it smartly.
