gdoc2adoc

This project contains two ways to convert a Google Document to asciidoc(tor) format.

The first one is most mature and uses Google Apps Script, the second one is more experimental and uses the Google Doc API.

Google Apps

A simple Google Apps script to convert a properly formatted Google Drive Document to asciidoc (.adoc) format, or rather more precisly asciidoctor compatible format.

Try it

You can explore this script on this Google Doc document - you just need to copy this to your own Google Drive to be able to run the script via the Tools or AsciiDoc menu.

Usage

• Adding this script to your doc (once per doc):

  • Open your Google Drive document (http://drive.google.com)

  • Tools → Script Manager > New

  • Select "Blank Project", then paste this code in and save.

    • Clear the myFunction() default empty function and paste the contents of converttoasciidoc.gapps into the code editor

    • File → Save

• Running the script (run as many times as you want):

  • AsciiDoc > Export File (Creates a new folder target in the same directory as the document. AsciiDoc and image files are stored in it. A warning is generated if a target directory already exists)

  • AsciiDoc > Export Email (Sends you an email with the AsciiDoc and image files)

Interpreted formats

Things not yet handled proper asciidoc way is marked with a todo.

• Text:

  • paragraphs are separated by two newlines

  • text styled as heading 1, 2, 3, etc is converted to AsciiDoc heading: =, ==, ===, etc

  • TODO: text formatted with Courier New is backquoted: text

  • links are converted to asciidoc format: url[anchortext]

• Lists:

  • Numbered lists are converted correctly, including nested lists

  • bullet lists are converted to “*” AsciiDoc format appropriately, including nested lists

  • Honors linebreak in paragraphs by using asciidoc line continuation ('+' on empty line)

• Images:

  • images are correctly extracted and sent as attachments

• Drawings:

  • not supported - there seems to be no API function to export a drawing as a rasterized or vector image.

• TODO: Equations:

  • Equaations are not supported.

• Table of contents:

  • Is handled by asciidoctor toc macros

• Horizontal line:

  • Inserts a ---

• Header/Footer:

  • Extracts text with all formattings and inserts it at the top and bottom of the AsciiDoc document, seperated by ---.

• Tables:

  • Converted to AsciiDoc tables. Formatting within cells gets transferred.

• Source code:

  • Fenced code blocks are started by three back-ticks and a string and ended by three back-ticks. If such a fenced code block is detected, single line break is used within it.

Google Doc API

This implementation is for now a proof-of-concept, lots of formatting not supported yet (contributions welcome)!

To use this you need to:

1. Enable Google Doc Api and get auth credentials and save it in credentials.json.

2. Install jbang

3. Run ./gdoc2adoc.java <url to google doc> > mydoc.adoc
