Markdown Reference Link

Posted by @pdavisonreiber, Last updated: 2018-07-04 13:10:36 UTC

Insert Markdown link [][1] in the text and add [1]: at the end of the document. If there is a text selection, use it as the link text; if a URL is in the clipboard, place it at the end of the document with the reference number. Numbers used for references automatically increment each time.

Steps

  • script

    /* 
    If no text is selected:
    - add reference link template [][1] at current cursor position
    - add reference [1]: at end of document, with link if clipboard contains URL 
    - move cursor to inside of [] for entering URL text
    
    If text is selected:
    - replace selection with [selection][1]
    - add reference [1]: at end of document, with link if clipboard contains URL
    - move cursor to after [selection][1] if link was added, or after reference [1]: if no link was added
    
    Script automatically increments reference number for each new link.
