Will there ever be a standard wiki-link?

Will there ever be a standard wiki-link?

[Joseph Reagle]

I'm noticing folks building wikis using markdown increasingly adopting the convention [[local link]]. However, gitit uses [local link](). Any chance one of these will be standardized or adopted by Pandoc?

Interesting... can you link to some example docs for those wikis?

I haven't been tracking it carefully, but I'm increasingly seeing references to "wiki style links" (double bracket) in wiki/notebook apps that use markdown.

Github wiki is probably the biggest driver, for example:

  https://github.com/reagle/New-Media-Culture/wiki

  https://github.com/reagle/New-Media-Culture/wiki/Home/_edit

I think Notational Velocity and its spawn are also influencing folks.

This is the recent example that prompted my email.

	https://github.com/darryllawson/sublime-notedown

And I'd like to suggest they follow the [link]() syntax of gitit, but don't know how to suggest they do so...

Ah. Didn't realize there was such an old issue. It would be nice to have a format extension...

I suppose that means it's too late for there to be a standard; my cursory glance at CommonMark didn't show any discussion of `[link]()` vs `[[link]]`. 

In fact, in CommonMark:

	[link]() 	▶ 		<p><a href="">link</a></p>	[1]

and an empty href quote, according to HTML, is an empty URI reference, pointing to the current document -- which is different than gitit.

It's the same in pandoc.  Gitit simply treats links with empty
URLs as wikilinks -- it's a convention that requires no
new syntax.

I think both [this syntax] and [this one][] is valid. The later might require adding a multimatkdown extension.

The attached Lua filter kind of does the trick if you want to generate 
Markdown e.g. for GitHub wikis. It converts three different "syntaxes"
into wiki link syntax:

   Get [[...]] style wiki links in Pandoc Markdown output:

   [PAGE NAME]() becomes [[PAGE NAME]]   (Formatting is lost)

   [FORMATTED TEXT]{wiki="PAGE NAME"}
       becomes [[PAGE NAME|FORMATTED TEXT]]

   `TEXT`{.wiki} becomes [[TEXT]]        (Very fast!)

       $ pandoc --lua-filter wiki-links.lua -w gfm
       [foo]() [*bar*]{wiki="baz"} `quux`{.wiki}
       ^D
       [[foo]] [[baz|*bar*]] [[quux]]

This ST extension, as well, uses double bracket.
