[!NOTE] Multiprocessing on Windows and MacOS is considerably slower than on Linux. Users are encouraged to test and see what works best for them.

Examples

Generate toc and edit before saving: pdfao paper.pdf

Generate and save to new pdf: pdfao paper.pdf -o new.pdf

Edit exiting pdf toc: pdfao paper.pdf -e

A save toc to new pdf from file: pdfao paper.pdf -o new.pdf -i outline.txt

Editing

The edit command opens the TOC in the OS default editor (result of 'start' command on Windows and 'EDITOR' environment variable on MacOS and Linux). The file schema is something like this:

Title 1  |  1
    Title 2  |  2  |  *
                 ^^^^^^
				 optional		

The essential parts of each line are:

• Indentation - 4 space characters per nesting level (or use tabs with the -t flag).
• Title text
• Delimiter - ' | ' (vertical bar with 2 spaces padding on each side)
• Page number

The optional part can be one of:

  |  None                  	same as not including it   
  |  241.2					y-ordinate 
  |  {<dictionary>}			dictionary with more attributes for the ToC entry

For Sioyek Users

Example commands; add to prefs_user.config.

new_command _gen_toc pdfao "%{file_path}" --sioyek path/to/sioyek -mp 4
new_command _edit_toc pdfao "%{file_path}"

The sioyek library and flag are optional; they allow logging to the status bar. This is more useful for ToC generation where you may want a progress bar.

If you don't wish to install from PyPI, download source and use python3 -m path/to/src/pdf_auto_outline in place of pdfao.
