How insert the outline (the bookmarks) into DjVu file for easier browsing in a document using the DjVuLibre library?

With such a structure:

  • "TOC" level 1 => link to pageNumber
  • "Chapter name" level 1 => link to pageNumber
    • "Chapter name" level 2 => link to pageNumber
  • "Chapter name" level 1 => link to pageNumber
    • "Chapter name" level 2 => link to pageNumber
      • "Chapter name" level 3 => link to pageNumber
  • "Chapter name" level 1 => link to pageNumber
    ...

First, create your desired structure in a text editor.

On the first line will be placed keyword bookmarks in round brackets as a root.

Behind the chapter titles are located page numbers or page names (with a suffix .djvu). Before the number must be symbol sharp #. All parameters are enclosed in quotation marks "".

Lower order chapters are created by embedding additional round brackets behind higher order chapter.

Sample with page numbers:

(bookmarks
    ("TOC" "#3")
    ("Chapter 1 - Blabla" "#7"
        ("Subchapter 1.1 - Blabla" "#11")
    )
    ("Chapter 2 - Blabla" "#15"
        ("Subchapter 2.1 - Blabla" "#17"
            ("Subchapter 2.1.1 - Blabla" "#20")
        )
    )
    ("Chapter 3 - Blabla" "#25")
)

Sample with page names (with a suffix .djvu):

(bookmarks
    ("TOC" "#page_0003.djvu")
    ("Chapter 1 - Blabla" "#page_0007.djvu"
        ("Subchapter 1.1 - Blabla" "#page_00011.djvu")
    )
    ("Chapter 2 - Blabla" "#page_00015.djvu"
        ("Subchapter 2.1 - Blabla" "#page_00017.djvu"
            ("Subchapter 2.1.1 - Blabla" "#page_00020.djvu")
        )
    )
    ("Chapter 3 - Blabla" "#page_00025.djvu")
)

Caution: Save the file in UTF-8.

Second, paste the created outline text file into the selected DjVu file.

Install the DjVuLibre library (if you do not already have it).
From the library we use djvused tool.

At the command prompt, type:

path\djvused path\book.djvu -e "set-outline path\outline.txt" -s

Instead path parameter substitute your location on the disk.
Parameter -e is the exec (system call) of the set-outline command with the filename parameter.
Parameter -s is save command.

Press Enter...

Although the following method does not explicitly use the DjVuLibre library (it does implicitly), the following method might save some of your precious time...

  • Use some tool to extract the contents from the djvu file. I recommend pdf_contents_extractor for python3 which can be easily installed with pip(pip3) (only tested on linux, but works for djvu too)
  • Fine-tune the contents.txt or contents_ocr.txt file with your favorite text editor
  • Use HandyOutliner to insert the bookmarks in your djvu file

  • I was not able to run HandyOutliner on Linux, and did not even find a [Mono] executable for Linux, even though the program's web page states that it is cross-platform. Would appreciate your help!

  • I used djvusmooth by Jakub WIlk for years, really liked it, and even added a Wikipedia entry on it, I believe. But it is Python 2-based, with some obsolete/legacy dependencies...

    Haha, I switched from Vim to Emacs about 3 years ago, and I completely understand the joke about the keybindings:) But I am just using Vim inside Emacs (it is called evil-mode). I started with using Spacemacs, which you could take a look at (I have created a toc layer for it also). As a Vim user, you will be immediately able to use it, and see what Emacs all has to offer. Actually, the main reason I switched to Emacs is that Emacs made it ridiculously easy to create doc-toc. Commented Aug 17, 2023 at 11:18
