TOC generate with btt-links.applescript

-- Generate a table of contents (TOC) in DEVONthink's Markdown documents.
-- The script also adds Back-to-toc links over each headline.
--
-- This script relies on an external Python script (works for both, Python 2 and 3). The path to the folder, that contains that Python script, must be added to this Applescript (in 'MyPythonScriptPath').

-- Please specify the path to the folder, where you've saved the Python script:
set MyPythonScriptPath to "<SET PATH TO THE PYTHON SCRIPT FOLDER>"
if MyPythonScriptPath = "<SET PATH TO THE PYTHON SCRIPT FOLDER>" then error "Error: Variable 'MyPythonScriptPath' not set. Please set the path of the folder, that contains the convert_wikilinks_to_markdown_links.py Python script."

-- On macOS < 12.3, set LocalPython to "/usr/bin/python". For higher macOS versions, install Python (e.g., via Anaconda.com or python.org), find out the path of your new Python installation (open a terminal and type "which python") and set LocalPython to the given result. The default setting below links to the Anaconda installation; in case you're also using Anaconda, please replace "<USER>" with your user name.
set LocalPython to "/Users/<USER>/opt/anaconda3/bin/python"
