Whitespace in Reference Links does not work

[BirgerNi]

Markdown links with whitespace work. The following link opens the file wiki file.md:

[wiki file](wiki file)

With reference style links there seem to be a problem with whitespace.

• Expected behaviour: opens file wiki file.md
• Actual behaviour: opens file wiki.md

Please let me know whether I can provide more information or there is a known workaround.

Thanks, the description is clear. The reason for this is that I am not sure if this is really desirable. It may be. I'm not sure if there is a canonical specification here, but I found this, which also differs from the current implementation.

I'm thinking that it could make sense to adhere to the commonmark spec, except, for simplicity, to avoid the newlines. What do you think?

By the way, I like the nomenclature used in the commonmark spec, so I could perhaps also update the docs and code to adhere the spec.

The common way seems to be just enclose the URL in angle bracket.

I think it is a good idea to follow a markdown spec like CommonMark which is fully supported by pandoc.

I believe the original issue is resolved now. Please test.

I've also updated the reference link support to be more or less according to the commonmarks spec, although with some limitations.

Your support is impressive. The issue is solved, thank you.

Thanks for the kind words :)

I believe wiki.vim is improved due to your suggestions, so thanks for raising the issue and contributing through the discussion!
