I second this request. Like in the original definition, simply have a top level note ‘InterWiki.md’ with a table of all the locally defined shortcuts.
It could have 4 fields:
shortcut - which is what you use for writing, eg foo:bar
link - to the (remote) destination, where %s (or similar) stands for the the link target bar
style - optional, if the plain style <a href=foo.site/%s.html>foo:bar</a> is not pretty enough, e.g. insert extra text, style, icons etc
Use the result and DuckDuckGo’s free Instant Answers API to get the URL, specifically their “!bang” redirect. It already has Wikipedia and Dictionary built in.
i love this idea (ps: i have a little creative exercise i like to do where i turn wikipedia text into rap songs and publish them online lol…i would totally have to use this plugin for that, along with so many other things)
