Sphinx with Markdown - How to use Markdown with Sphinx (including Markdown tables that Sphinx does not handle by default for PDF and HTML output)

Sphinx with Markdown walkthrough for HTML and PDF output

This walkthrough installs Sphinx and configures it to output HTML and PDF from .md. If you install it on a VM, allocate over 25GB storage and multiple processors. You'll need Ubuntu 16.04 LTS, an internet connection, and sudo rights.

PDF output from Markdown

This edition of the walkthrough corrects an issue with using make latexpdf previously. make latexpdf would produce .tex output from .md for Sphinx to make a .pdf. But make latexpdf did not successfully make tables in .pdf from tables in .md.

This was due to the sphinx-markdown-tables package not outputting .tex from .md. sphinx-markdown-tables will output .html from .md, but not .tex from .md. .tex is required for pdflatex, which is run by Sphinx to make .pdf from .tex.

sphinx-markdown-tables has a issue with .md tables for .pdf that won't be fixed. (ryanfox/sphinx-markdown-tables#3). pandoc is the work-around.

pandoc and texlive are installed and make latex is used to do this successfully. To make these steps portable, put sudo commands in a .sh script to run from bash. You'll also need to edit the Makefile produced by Sphinx to run pandoc for .pdf.

Customizing HTML output

When generating HTML documentation with Sphinx, you can adjust some theme related settings with html_theme_options in conf.py. However, the available options are restricted since they are restricted to the [options] section in theme.conf, which are specific to a given theme.

So to customise the theme related settings on a global basis, you can define htm_context to add custom CSS defined in _static/custom.css that gets included in the generated HTML.

The steps to configure conf.py after intallation have been extended for custom.css. custom.css is applied to override the default CSS applied by bootstrap and bootswatch. Sphinx imports bootstrap and bootswatch at build time, so custom.css is needed as well. Using custom.css makes these steps portable to run Sphinx on another VM, or via Jenkins.

You must download a Bootswatch 3.3.7 CSS to edit for a custom.css from https://bootswatch.com/3/ The default Bootswatch URL (https://bootswatch/com) will download Bootswatch 4.1.3 that won't work.

Installation

Update Ubuntu

$ sudo apt update -y
$ sudo apt upgrade -y
$ sudo apt dist-upgrade -y

Note

Updates may take 5 minutes to complete.

Install Python and update pip

$ sudo apt-get install python-pip -y
$ sudo pip install --upgrade pip

Install Sphinx and HTML themes

$ sudo pip install sphinx
$ sudo pip install sphinxjp.themes.basicstrap
$ sudo pip install sphinx_bootstrap_theme

Install TeX Live for PDF

$ sudo apt-get install texlive-full -y

Note

Installing and unpacking Tex Live may take 20 minutes.

Install recommonmark to parse .md

$ sudo pip install recommonmark

Install sphinx-markdown-tables version 0.0.3 to parse .md tables for HTML output

$ sudo pip install sphinx-markdown-tables==0.0.3

Running just sudo pip install sphinx-markdown-tables without specifying the version installs the latest version. I initially installed version 0.0.3 that worked then reinstalled the latest version 0.0.8, which did not run. sudo pip install sphinx-markdown-tables==0.0.3 installs version 0.0.3, which I've tested and know works well.

Install pandoc version 1.16.0.2 to parse .md tables for PDF output

$ sudo wget https://github.com/jgm/pandoc/releases/download/1.16.0.2/pandoc-1.16.0.2-1-amd64.deb
$ sudo dpkg -i pandoc-1.16.0.2-1-amd64.deb

Running just sudo apt-get install pandoc without specifying the version installs the latest version. I had problems running the latest version so I install the version I have tested and know works reliably. sudo dkpg -i pandoc-1.16.0.2-1-amd.deb installs version 1.16.0.2 after first downloading it with: sudo wget http://github.com/jgm/pandoc/releases/download/1.16.0.2/pandoc-1.16.0.2-1-amd.deb.

Note

This is the last installation step. Close the terminal and open a new terminal without sudo, as the sphinx-quickstart script creates privileged files to edit. If you don't then you'll need to chown privileged files, so you can edit them.

Install and configure Atom to edit .md

$ sudo add-apt-repository ppa:webupd8team/atom
$ sudo apt update
$ sudo apt install atom

Enter Y when prompted: After this operation, 112MB of additional disk will be used. Do you want to continue? [Y/n].

Note

This step to install and unpack Atom may take 5 minutes to complete.

Install Atom support for .md

Select Edit > Preferences > Install. Search for and install language-markdown.

markdown-preview installed by default gives an preview with <Ctrl><Shift>M.

Edit index.rst in Atom to add .md files

.. toctree::
   :glob:
   :maxdepth: 2

    <your_document>

Note

Don't add an .md suffix for .md files added to index.rst.

Put a blank line after :maxdepth: 2 before <your_document>.

Add lines at the start of conf.py

import recommonmark
from recommonmark.transform import AutoStructify
from recommonmark.parser import CommonMarkParser
source_parsers - {
   '.md': CommonMarkParser
}

import sphinx_bootstrap_theme

Add these lines at the end of conf.py

def setup(app):
    app.add_config_value('recommonmark_config', {
            'enable_math': True,
            'enable_eval_rst': True,
            'enable_auto_doc_ref': True,
            'auto_code_block': True,
            }, True)
    app.add_transform(AutoStructify)

Find and replace html_theme in conf.py

html_theme - 'bootstrap'
html_theme_path - sphinx_bootstrap_theme.get_html_theme_path()

html_theme_options - {
    'bootswatch_theme': "darkly",
    'bootstrap_version': "3",
}

Add sphinx_markdown_tables in conf.py

extensions = [
    'sphinx.ext.autodoc',
    'sphinx.ext.doctest',
    'sphinx.ext.coverage',
    'sphinx.ext.mathjax',
    'sphinx.ext.ifconfig',
    'sphinx.ext.githubpages',
    'sphinx_markdown_tables']

Find and replace source_suffix in conf.py

source_suffix - ['.rst', '.md']

Add html_context in conf.py for custom.css in source/_static folders

html_context = {
    'css_files': {'_static/custom.css'}

Make custom.css from bootstrap.css and copy to source/_static folders

  • Download a suitable bootstrap.css for the Bootswatch theme (https://www.bootswatch.com/3/) darkly, which you will edit and rename to make the custom.css file.
  • Edit a downloaded bootstrap.css to save a custom.css, changing text font and background color options with hexadecimal color codes (https://www.htmlcolorcodes.com).
  • Copy a saved custom.css into the source/_static folder for each of the guides you need to apply overrides to bootstrap-sphinx.css, which is applied by default.
  • Use the broswer inspector to find hex color values applied to the output HTML from bootstrap.css that you then modify in custom.css to override default CSS colors.

Note

You must download a Bootswatch 3.3.7 CSS to edit for a custom.css from https://bootswatch.com/3/

The default Bootswatch URL (https://bootswatch/com) will download Bootswatch 4.1.3 that won't work.

Update Makefile to run pandoc from make latex

In Makefile find:

%:Makefile
  @$(SPHINXBUILD) -M $@ "$(SOURCEDIR)" "$(BUILDDIR)" $(SPHINXOPTS) $(0)

and replace it with:

html:
  @$(SPHINXBUILD) -M $@ "$(SOURCEDIR)" "$(BUILDDIR)" $(SPHINXOPTS) $(0)

latexpdf:
  @$(SPHINXBUILD) -M $@ "$(SOURCEDIR)" "$(BUILDDIR)" $(SPHINXOPTS) $(0)

latex:
  @pandoc --toc --latex-engine=pdflatex -V fontfamily="cmbright" -V geometry=margin=0.5in -V documentclass="book" -o /build/<output>.pdf -s <input_1>.md <input_N>.md <copyright>.md

Note

Creating latexpdf:, html:, and latex: entries in Makefile enables you to output PDF and HTML from .md and .rst.

make html will call html: in Makefile to output HTML from .md and .rst.

make latexpdf will call latexpdf: in Makefile to output PDF from .rst only.

make latex will call latex: in Makefile to run pandoc to make PDF from .md only.

<output>.pdf is the filename for the PDF output file with a .pdf suffix.

<input_1>.md is the filename for the first Markdown file in a series of content files for a single book with an .md suffix.

<input_N>.md is the filename for the last Markdown file in a series of content files for a single book with an .md suffix.

<copyright>.md is the filename for the Markdown source file required for the copyright notice to match index.rst.

pandoc will combine multiple Markdown source files into a single PDF file so each Markdown file can be a chapter in a book.

fontfamily specifies the texlive font for the main font. This is a sans-serif font that doesn't affect monospaced fonts in code blocks.

margin specifies the margin width in inches. 0.5 inch margins will print on most printers. 0.25 inch margins may cut off on some printers.

documentclass specifies the format applied by pandoc. "book" is applied because it follows a book structure used with fncychp.

Update your initial .md file with cover information

Add the below cover information at the start of your initial .md file:

---
title: <document-title>
author: <author>
date: <current-date>
output: pdf_document
---

pandoc will put this information on a cover page in the .pdf output.

Make an .md copyright notice for pandoc to append:
