Bookends is reference management by Sonny software.

Hook supports Bookends. By default, Copy Link and Copy Markdown Link in Bookends return links of the form bookends://.

If you would rather traffic in hook://file/ links, then Hook Pro users may the alternative Hook-Bookends integration script below. To do this just

open Hook > Preferences > Script Editor tab, then
select Bookends,
select the Get Address tab
paste the script below into the tab.
click Save

and you’re done.

The alternative script is:

tell application id "com.sonnysoftware.bookends"

    set selectedItems to selected publication items of front library window
    if selectedItems is not {} then
        set selectedUrl to url of item 1 of selectedItems
        if selectedUrl is not equal to "" then
            get properties of item 1 of selectedItems
            return "bookends://sonnysoftware.com/" & id of item 1 of selectedItems
        else
            set a to attachments of item 1 of selectedItems
            if a is equal to "" then
                return "bookends://sonnysoftware.com/" & id of item 1 of selectedItems
            end if
            return "file://" & default attachments path & a
        end if

    end if
end tell

The main advantage of using hook://file/ links rather than bookends:// links is that it gives you access to all the hooks regardless of whether you access the PDF in Bookends or in a different app. So if you choose to use Finder, PDFPenPro, Skim, Preview or another app, hook://file/ links have you covered.

The disadvantage is that currently hook://file/ links are not available on iOS /iPadOS side. But we intend to remedy that. Also, the the name of the hook://file/ links are the file name, not the default citation format.
