Export to Netscape Bookmark format

[morgandavidson]

Netscape Bookmark format is used by main browsers (Chrome, MS browsers, Firefox) to export and import browsers bookmarks to HTML.

I find it much easier to manage and centralize browser bookmarks with Org-Mode.

Here is an example of an org file storing some bookmarks (note that in browser bookmarks each heading would correspond to a folder and each link to a bookmark):

* Data
** Finance
*** Crypto

* Webapps
** Code
*** Bash

  finds bugs in your shell scripts.
*** JSON

  jq is a lightweight and flexible command-line JSON processor.

Unfortunately, I didn't find any tool allowing exporting bookmarks from a markup format to Netscape Bookmark format.

I thought that this feature might be in the scope of Pandoc.

This seems a bit too specialized to me. The perfect use case for a custom Lua writer.

At first, I thought of an Elisp tweak for emacs. Indeed a Lua script might be well adapted for the use case.

Here is how Org-Mode managed bookmarks could be exported to Netscape Bookmarks :

• Have the following block at the beginning of the exported HTML

<!DOCTYPE NETSCAPE-Bookmark-file-1>
<!--This is an automatically generated file.
    It will be read and overwritten.
    Do Not Edit! -->
<Title>Bookmarks</Title>
<H1>Bookmarks</H1>

• The rest of the exported HTML should be as follow, where {item} may be either a folder or a bookmark:

<DL>
 {item}
 {item}
 {item}
 .
 .
 .
</DL>

• If {item} refers to a folder, it is:

<DT><H3 FOLDED ADD_DATE="{date}">{title}</H3>
<DL><p>
 {item}
 {item}
 {item}
 .
 .
 .
</DL><p>  

Where {date} is a decimal integer that represents the number of seconds elapsed since midnight January 1, 1970, e.g. 1661350152. And {title} is the name of the folder corresponding to an orgdown headline.

• If {item} refers to a bookmark, it is:

<DT><A HREF="{Bookmark URL}" ADD_DATE="{date}" LAST_MODIFIED="1661350203">{Bookmark Name}</A>  

Corresponding to Orgdown [[{Bookmark URL}][{Bookmark Name}]]
