require 'uri'

VAULT_NAME = 'ZETTELKASTEN' 

def class_exists?(class_name)
  klass = Module.const_get(class_name)
  return klass.is_a?(Class)
rescue NameError
  return false
end

if class_exists? 'Encoding'
  Encoding.default_external = Encoding::UTF_8 if Encoding.respond_to?('default_external')
  Encoding.default_internal = Encoding::UTF_8 if Encoding.respond_to?('default_internal')
end

begin
  input = STDIN.read.force_encoding('utf-8')
rescue
  input = STDIN.read
end

input.gsub!(/\[\[(.*?)\]\]/) do |m|
  match = Regexp.last_match
  if match[1].include?('|') 
    splits = match[1].split('|')
    "[#{splits[1]}](obsidian://vault/" + ::VAULT_NAME + "/#{URI.escape(splits[0])})"
  else
    "[#{match[1]}](obsidian://vault/" + ::VAULT_NAME + "/#{URI.escape(match[1])})"
  end
end

print input

This simple preprocessor will make Obsidian [[WikiLinks]] clickable within Marked2 app.
Links will open appropriate file in Obsidian via its URL scheme.

Instructions:

1. Clone the script to you local computer
2. Inside the script change the VAULT_NAME constant to the vault of your choice and save the changes
3. Open Marked2 and go to app Preferences
4. In the "Advanced" tab select "Preprocessor" and provide your local path to the script

That's it.

Script should take care of your WikiLinks along with aliases if there are some

Side note

I'm using this along with Marked2 Custom Preprocessor option and pandoc for rendering my Obsidian notes for the output, be it PDF, ODT, DOCX, RTF or HTML. Marked2 is very powerfull in that regard, allowing me to have References rendered from Zotero via autoupdated .bib file. I use that capabilities mostly for bigger Outlines, essays or papers where such case is a must.

full Args are (change your paths of course, and pick up style of your liking)

--citeproc -f markdown -M lang=pl-PL -t html5 --csl=/your/path/to/chicago.csl --bibliography=/your/path/to/Library.bib

With those in place sth like below is possible. The note is in Polish so sorry for that but you can see references - in Chicago style - rendered at the bottom

This is fantastic. Thank you for sharing!
