Internal Links in MediaWiki? (pandoc 1.10.1)

[Milofax]

I try to create internal links in mediawiki that should point in the end to another wiki page. Therefore, I have different md-files that represent a wiki page each.
For wiki, I convert each md-file separately to mediawiki. I also use the pdf conversion which works fine (and where I convert the content at once).
I would like to have the behaviour that internal links as [OtherWikiPage] would be converted to Mediak Wiki like [[OtherWikiPage]]. At the moment, pandoc doesn't interpret it at all.
Is that possible?

At some point I plan to add optional support for [[Wikilinks]] to
pandoc markdown. But for now, no.

Note: You can always define link references at the end of your
document for each of your pages:

[OtherWikiPage]: /url-to-page-in-wiki "wikilink"

I also thought about that but I also want to have these links working when I create a pdf out of the same files. I did a temporary solution by writing a script that does all the work in finding the links that refer to external sources (=WikiPages) and the pdf conversion doesn't break.

I'm not sure why it wouldn't work for PDF...? Reference links work
for PDFs too. Of course you'd want to use relative paths.

[Milofax]

Because I want to use the same Link e.g. [Link] for both formats. In wiki conversion this link should become [[Link]], in pdf, this is still an internal link to a Heading in the document that was made by several md-files, each one representing a wiki page. I know, there's a lot of convention involved. Does that make sense?

[marcbowes]

With org to mediawiki:

[[Link]]

becomes

''Link''

Any idea how I can get this to be a relative link? I'm building from org to HTML and mediawiki, so I'm not keen on using absolute URLs.

[mpickering]

@marcbowes, for the uneducated what should the result be? [[Link]] is parsed as Emph in Org mode. One possible way would be to use span elements with a filter. If you need help with the approach post back here.

[marcbowes]

Definitely would appreciate help on rel links still.

The actual mediawiki syntax is [[Link Title]]. I would expect to be able to type something similar in org, possible [[Link][Title]].

It seems the org-mode parser only treats the link as a link if it looks like a URI/file etc: https://github.com/jgm/pandoc/blob/master/src/Text/Pandoc/Readers/Org.hs#L1145

[mpickering]

It looks like it's an arbitrary choice to turn unrecognised links into Emph? If so then it might be better to turn them into Span elements with a custom class - that would at least make our lives much easier.

@tarleb am I correct in thinking this?

[tarleb]

am I correct in thinking this?

Pretty much, yes. It's not completely arbitrary, in that it mirrors emacs' export behavior, but could very well be changed to something different.

Issue #1741 and jgm/gitit#471 are related to this. The resolving commit now allows empty urls, making it possible to define new wiki links like this: [[][Link]. It sounds like that is still insufficient for the use case at hand, so changing the reader might be the right thing to do.

[tarleb]

One additional note, though: Org-mode uses the [[Link][Title]] syntax to define links to internal headlines. More specifically, it starts a search for Link in all headlines. The reader doesn't support it yet, and neither does the Emacs exporter (hence the current behavior). The search will probably never work for Pandoc converted files, but converting the above to anchor links might be a decent replacement. That's why I'd argue that the [[Link][Title]] syntax isn't a good choice for wiki links. Maybe just use [[./Link][Title]] instead? Or define a custom link type with #+LINK: wiki ./ and write [[wiki:Link][Title]].

[marcbowes]

That comes out as [[./Link|Title]] for me on both .12 and .13.1.

[tarleb]

Yes, I was wrong the first time: [[file:Link][Title]] would be the correct way to put it. Unfortunately, the org reader doesn't recognize it yet. I'll try to provide a fix later this week. After that, the afore mentioned link alias should look like this: #+LINK: wiki file:%s.

Thanks for pointing it out!

[marcbowes]

Would I have to add that to every page I author? How would this impact the HTML writer?

The entire list of my link use-cases (author in org, export to mw and html):

1. I want to be able to link to a relative path,
2. to a section in the page (anchor links)
3. and to an absolute URL

[mpickering]

Due to my inexperience with org I'm struggling to conceptualise example how Albert's suggestion would work. My original idea was to write a filter to intercept links and rewrite then based on the output format.
