Markdown Package User Manual

v2.8.1 (2019/04/30)

1 Introduction

The Markdown package converts markdown markup to TeX commands. The functionality is provided both as a Lua module and as plain TeX, LaTeX, and ConTeXt macro packages that can be used to directly typeset documents containing markdown markup. Unlike other convertors, the Markdown package makes it easy to redefine how each and every markdown element is rendered. Creative abuse of the markdown syntax is encouraged.

This document is a user manual for the Markdown package. It provides tutorials and code examples. For an in-depth description of the package requirements, interfaces, and implementation, please refer to the technical documentation.

1.1 Requirements

The package requires a working TeX distribution. TeX Live ≥ 2013 is known to work and so are recent installation of MikTeX. If you are using a minimal installation of a TeX distribution, please consult the technical documentation for a detailed list of required packages.

1.2 Installation

The package comes pre-installed with TeX Live ≥ 2016 and with recent installations of MikTeX. Unless you explicitly wish to use the latest version of the package, you are encouraged to skip this step.

To install the package, first download the package from the repository using Git:

git clone https://github.com/witiko/markdown

Next, enter the directory named markdown and interpret the file named markdown.ins file using a Unicode-aware TeX engine, such as XeTeX or LuaTeX:

cd markdown
luatex markdown.ins

This should produce the following files:

1.2.1 Local Installation

To perform a local installation, place the above files into your TeX directory structure. This is generally where the individual files should be placed:

where <TEXMF> corresponds to a root of your TeX distribution, such as /usr/share/texmf and ~/texmf on UN*X systems or C:\Users\Your username\texmf on Windows systems. When in doubt, consult the manual of your TeX distribution.

1.2.2 Portable Installation

Alternatively, you can also store the above files in the same folder as your TeX document and distribute them together. This way your document can be portably typeset on legacy TeX distributions.

1.3 First Document

In this section, we will take the necessary steps to typeset our first markdown document in TeX. This will serve as our first hands-on experience with the package and also as a reassurance that the package has been correctly installed.

1.3.1 Using Lua

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input hello
\bye

1.3.1.1 Using the Lua Module

Using a text editor, create a text document named hello.lua with the following content:

#!/usr/bin/env texlua
local kpse = require("kpse")
kpse.set_program_name("luatex")
local markdown = require("markdown")
local convert = markdown.new()
print(convert("Hello *world*!"))

Next, invoke LuaTeX from the terminal:

texlua hello.lua > hello.tex
luatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” Invoking pdfTeX should have the same effect:

texlua hello.lua > hello.tex
pdftex document.tex

1.3.1.2 Using the Lua Command-Line Interface

Using a text editor, create a text document named hello.md with the following content:

Hello *world*!

Next, invoke LuaTeX from the terminal:

texlua ⟨CLI pathname⟩ -- hello.md hello.tex
luatex document.tex

where ⟨CLI pathname⟩ corresponds to the location of the Lua CLI script file, such as ~/texmf/scripts/markdown/markdown-cli.lua on UN*X systems or C:\Users\Your username\texmf\scripts\markdown\markdown-cli.lua on Windows systems. Use the command kpsewhich markdown-cli.lua to locate the Lua CLI script file using Kpathsea.

A PDF document named document.pdf should be produced and contain the text “Hello world!” Invoking pdfTeX should have the same effect:

texlua ⟨CLI pathname⟩ -- hello.md hello.tex
pdftex document.tex

1.3.2 Using Plain TeX

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\markdownBegin
Hello *world*!
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” Invoking pdfTeX should have the same effect:

pdftex --shell-escape document.tex

1.3.3 Using LaTeX

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage{markdown}
\begin{document}
\begin{markdown}
Hello *world*!
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” Invoking pdfTeX should have the same effect:

pdflatex --shell-escape document.tex

As the next step, try typesetting the example documents distributed along with the Markdown package:

git clone https://github.com/witiko/markdown
cd markdown/examples
lualatex latex.tex

A PDF document named latex.pdf should be produced. Open the text documents latex.tex and example.md in a text editor to see how the example documents are structured. Try changing the documents and typesetting them as follows:

lualatex latex.tex

to see the effect of your changes.

1.3.4 Using ConTeXt

Using a text editor, create a text document named document.tex with the following content:

\usemodule[t][markdown]
\starttext
\startmarkdown
Hello *world*!
\stopmarkdown
\stoptext

Next, invoke LuaTeX from the terminal:

context document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” Invoking pdfTeX should have the same effect:

texexec --passon=--shell-escape document.tex

As the next step, try typesetting the example documents distributed along with the Markdown package:

git clone https://github.com/witiko/markdown
cd markdown/examples
context context.tex

A PDF document named context.pdf should be produced. Open the text documents context.tex and example.md in a text editor to see how the example documents are structured. Try changing the documents and typesetting them as follows:

context context.tex

to see the effect of your changes.

2 Examples

In this section, I will describe the individual parts of the Markdown package. Each part will be shown by example, leaving the implementation details to the technical documentation.

2.1 Interfaces

In this section, I will describe the individual interfaces exposed by the Markdown package starting with the low-level Lua interfaces and all the way up to the LaTeX and ConTeXt interfaces intended for the ordinary user.

2.1.1 Lua

The Lua programming language is what drives the conversion from markdown to TeX in the Markdown package. Based on the Lunamark Lua library by John MacFarlane, the Lua implementation is largely independent on TeX, and can be used separately from typesetting a document. Lua provides two interfaces: a Lua module and a command-line interface (CLI).

2.1.1.1 Lua Module

A Lua module is a software library that can be used from in other programs. The markdown Lua module makes it possible to convert markdown to TeX from within LuaTeX documents and Lua scripts.

The markdown Lua module exposes the new(options) method, which creates a converter function from markdown to TeX. The properties of the converter function are specified by the Lua table options. The parameter is optional; when unspecified, the behaviour will be the same as if ⟨options⟩ were an empty table.

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input lmfonts
\input example
\bye

Using a text editor, create a text document named example.lua with the following content:

#!/usr/bin/env texlua
local kpse = require("kpse")
kpse.set_program_name("luatex")
local markdown = require("markdown")
local input, convert_safe, convert_unsafe, paragraph

input = [[$\sqrt{-1}$ *equals* $i$.]]
convert_safe = markdown.new()
convert_unsafe = markdown.new({hybrid = true})
paragraph = [[\par]]

print(
  convert_safe(input) .. paragraph ..
  convert_unsafe(input)
)

Next, invoke LuaTeX from the terminal:

texlua example.lua > example.tex
luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

Invoking pdfTeX should have the same effect:

texlua example.lua > example.tex
pdftex document.tex

Rather than use the texlua interpreter, we can also access the markdown Lua module directly from our document. Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input lmfonts
\directlua{
  local markdown = require("markdown")
  local input, convert_safe, convert_unsafe, paragraph

  input = [[$\string\sqrt{-1}$ *equals* $i$.]]
  convert_safe = markdown.new()
  convert_unsafe = markdown.new({hybrid = true})
  paragraph = [[\par]]

  tex.sprint(
    convert_safe(input) .. paragraph ..
    convert_unsafe(input)
  )
}
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

In this case, we cannot use pdfTeX, because pdfTeX does not define the \directlua TeX command.

2.1.1.2 Lua Command-Line Interface

The Lua command-line interface (CLI) of the Markdown package makes the functionality of the Lua module accessible from the command line. This makes it possible to convert documents from markdown to TeX manually without any knowledge of the Lua programming language.

The Lua command-line interface accepts the same options as the markdown Lua module, but now the options are specified as command-line parameters.

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input lmfonts
\input safe

\input unsafe
\bye

Using a text editor, create a text document named example.md with the following content:

$\sqrt{-1}$ *equals* $i$.

Next, invoke LuaTeX from the terminal:

texlua ⟨CLI pathname⟩ -- example.md safe.tex
texlua ⟨CLI pathname⟩ hybrid=true -- example.md unsafe.tex
luatex document.tex

where ⟨CLI pathname⟩ corresponds to the location of the Lua CLI script file, such as ~/texmf/scripts/markdown/markdown-cli.lua on UN*X systems or C:\Users\Your username\texmf\scripts\markdown\markdown-cli.lua on Windows systems. Use the command kpsewhich markdown-cli.lua to locate the Lua CLI script file using Kpathsea.

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

Invoking pdfTeX should have the same effect:

texlua ⟨CLI pathname⟩ -- example.md safe.tex
texlua ⟨CLI pathname⟩ hybrid=true -- example.md unsafe.tex
pdftex document.tex

2.1.2 Plain TeX

The plain TeX interface provides TeX commands that typeset markdown documents by using the Lua interface behind the scenes. Unlike the Lua interface, the plain TeX interface does not provide low-level tools for converting markdown to TeX. Instead, its goal is to provide high-level typesetting capabilities.

The plain TeX interface accepts the same options as the markdown Lua module, in addition to its own options, but now the options are specified as TeX commands.

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input lmfonts

\markdownBegin
$\sqrt{-1}$ *equals* $i$.
\markdownEnd

\def\markdownOptionHybrid{true}
\markdownBegin
$\sqrt{-1}$ *equals* $i$.
\markdownEnd

\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

Invoking pdfTeX should have the same effect:

pdftex --shell-escape document.tex

2.1.3 LaTeX

The LaTeX interface provides the same level of functionality as the plain TeX interface by using the plain TeX interface behind the scenes. Unlike the plain TeX interface, the LaTeX interface uses familiar LaTeX idioms, such as package options and environments.

The LaTeX interface accepts the same options as the plain TeX interface, but now the options are specified as ⟨key = value⟩ pairs and they are passed either as package options, in the \markdownSetup command, or as parameters for the markdown* LaTeX environment.

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage{markdown}
\begin{document}

\begin{markdown}
$\sqrt{-1}$ *equals* $i$
\end{markdown}

\begin{markdown*}{hybrid}
$\sqrt{-1}$ *equals* $i$
\end{markdown*}

\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

Invoking pdfTeX should have the same effect:

pdflatex --shell-escape document.tex

2.1.4 ConTeXt

The ConTeXt interface provides the same level of functionality as the plain TeX interface by using the plain TeX interface behind the scenes. Unlike the plain TeX interface, the ConTeXt interface uses familiar ConTeXt idioms, such as environments.

The ConTeXt interface accepts the same options as the plain TeX interface.

Using a text editor, create a text document named document.tex with the following content:

\usemodule[t][markdown]
\starttext

\startmarkdown
$\sqrt{-1}$ *equals* $i$.
\stopmarkdown

\def\markdownOptionHybrid{true}
\startmarkdown
$\sqrt{-1}$ *equals* $i$.
\stopmarkdown

\stoptext

Next, invoke LuaTeX from the terminal:

context document.tex

A PDF document named document.pdf should be produced and contain the following text:

$\sqrt{-1}$ equals $i$.

√-̅1̅ equals i.

Invoking pdfTeX should have the same effect:

texexec --passon=--shell-escape document.tex

2.2 Options

In this section, I will describe all the options recognized by the Markdown package.

2.2.1 Lua

Lua options control the conversion from markdown to TeX. They are supported by all interfaces of the Markdown package starting with the low-level Lua interfaces and all the way up to the LaTeX and ConTeXt interfaces.

2.2.1.1 Option cacheDir

cacheDir (default value: ".")

A path to the directory containing auxiliary cache files. If the last segment of the path does not exist, it will be created by the Lua command-line and plain TeX implementations. The Lua implementation expects that the entire path already exists.

When iteratively writing and typesetting a markdown document, the cache files are going to accumulate over time. You are advised to clean the cache directory every now and then, or to set it to a temporary filesystem (such as /tmp on UN*X systems), which gets periodically emptied.

Lua Module Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\directlua{
  local markdown = require("markdown")
  local convert = markdown.new({cacheDir = "cache"})
  local input = "Hello *world*!"
  tex.sprint(convert(input)) }
\bye

Create an empty directory named cache next to our text document. Then, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” Several cache files of the Markdown package will also be produced in the cache directory as we requested using the cacheDir option.

Lua CLI Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\input hello
\bye

Using a text editor, create a text document named hello.md with the following content:

Hello *world*!

Next, invoke LuaTeX from the terminal:

texlua ⟨CLI pathname⟩ cacheDir=cache -- hello.md hello.tex
luatex document.tex

where ⟨CLI pathname⟩ corresponds to the location of the Lua CLI script file, such as ~/texmf/scripts/markdown/markdown-cli.lua on UN*X systems or C:\Users\Your username\texmf\scripts\markdown\markdown-cli.lua on Windows systems. Use the command kpsewhich markdown-cli.lua to locate the Lua CLI script file using Kpathsea.

A PDF document named document.pdf should be produced and contain the text “Hello world!” A directory named cache containing several cache files of the Markdown package will also be produced as we requested using the cacheDir option.

Plain TeX Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\def\markdownOptionCacheDir{cache}
\markdownBegin
Hello *world*!
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” A directory named cache containing several cache files of the Markdown package will also be produced as we requested using the cacheDir option.

LaTeX Example

\documentclass{article}
\usepackage[cacheDir=cache]{markdown}
\begin{document}
\begin{markdown}
Hello *world*!
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” A directory named cache containing several cache files of the Markdown package will also be produced as we requested using the cacheDir option.

ConTeXt Example

Using a text editor, create a text document named document.tex with the following content:

\usemodule[t][markdown]
\def\markdownOptionCacheDir{cache}
\starttext
\startmarkdown
Hello *world*!
\stopmarkdown
\stoptext

Next, invoke LuaTeX from the terminal:

context document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” A directory named cache containing several cache files of the Markdown package will also be produced as we requested using the cacheDir option.

2.2.1.17 Option hybrid

hybrid (default value: true)
true

Disable the escaping of special plain TeX characters, which makes it possible to intersperse your markdown markup with TeX code. The intended usage is in documents prepared manually by a human author. In such documents, it can often be desirable to mix TeX and markdown markup freely.

false

Enable the escaping of special plain TeX characters outside verbatim environments, so that they are not interpretted by TeX. This is encouraged when typesetting automatically generated content or markdown documents that were not prepared with this package in mind.

\def\markdownOptionOutputDir{output-directory}
\def\markdownOptionCacheDir{output-directory/cache-directory}
\markdownBegin
Hello *world*!
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex --output-directory output-directory document.tex

A text document named temporary-input.md should be produced in the folder named output-directory and contain the following text:

Hello *world*!

A folder named output-directory/cache-directory should also be produced and contain fragments of the converted markdown document. LuaTeX does not need other temporary files to perform the conversion from markdown to TeX. To produce the remaining temporary files, invoke pdfTeX from the terminal:

pdftex --output-directory output-directory --shell-escape document.tex

Text documents named helper-script.lua, and temporary-output.md should be produced in the folder named output-directory. The document named helper-script.lua will contain Lua code that was executed to convert markdown to plain TeX. The document named temporary-output.tex will contain the input markdown document converted to TeX.

No document named error-output.txt should be produced in the folder named output-directory. This document would only be produced if an error had occured while executing the Lua code. If this happens, please file a bug.

2.2.2.2 Package Documentation

The \markdownOptionStripPercentSigns macro controls whether a percent sign (%) at the beginning of a line will be discarded when reading Markdown input from a TeX document. This enables the use of markdown when writing TeX package documentation using the Doc LaTeX package by Frank Mittelbach.

Using a text editor, create a text document named document.dtx with the following content:

% \iffalse
\documentclass{ltxdoc}
\usepackage[stripPercentSigns]{markdown}
\begin{document}
\DocInput{document.dtx}
\end{document}
% \fi
%
% \begin{markdown}
% Hello *world*!
% \end{markdown}

Next, invoke LuaTeX from the terminal:

lualatex document.dtx

A PDF document named document.pdf should be produced and contain the text “Hello world!”

2.3 Markdown Tokens

A key feature of the Markdown package is the support for manipulating markdown tokens, such as headings, emphasized text, links, and lists, in TeX. Instead of reducing TeX to a PDF document producer, the Markdown package allows the user to specify how every markdown token should be processed and rendered.

2.3.1 Token Renderers

Token renderers are user-defined TeX macros, which render markdown tokens. In this section, I will describe the individual token renderers.

2.3.1.1 Interblock Separator Renderer

The \markdownRendererInterblockSeparator macro represents a separator between two markdown block elements. The macro receives no arguments.

Plain TeX Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\def\markdownRendererInterblockSeparator{%
  \par
  {\it(The end of a block)}%
  \par
}
\markdownBegin
Hello *world*!

_Foo_ bar!
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Hello world!

(The end of a block)

Foo bar!

LaTeX Example

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage{markdown}
\markdownSetup{
  renderers = {
    interblockSeparator = {%
      \par
      \emph{(The end of a block)}%
      \par
    },
  },
}
\begin{document}
\begin{markdown}
Hello *world*!

_Foo_ bar!
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Hello world!

(The end of a block)

Foo bar!

ConTeXt Example

Using a text editor, create a text document named document.tex with the following content:

\usemodule[t][markdown]
\def\markdownRendererInterblockSeparator{%
  \par
  \emph{(The end of a block)}%
  \par
}
\starttext
\startmarkdown
Hello *world*!

_Foo_ bar!
\stopmarkdown
\stoptext

\input markdown
\def\markdownRendererLineBreak{%
  \par
  {\it(A forced linebreak)}%
  \par
}
\markdownInput{example.md}
\bye

Using a text editor, create a text document named example.md with the following content. Note the two spaces at the end of the first line, which specify a hard linebreak. Due to the limitations of the TeX input processor, hard linebreaks would be ignored if we typed them directly into the document.tex document.

Hello world!  
_Foo_ bar!

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Hello world!

(A forced linebreak)

Foo bar!

LaTeX Example

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}

      \emph{(A forced linebreak)}%
      \par
    },
  },
}
\begin{document}
\markdownInput{example.md}
\end{document}

Using a text editor, create a text document named example.md with the following content. Note the two spaces at the end of the first line, which specify a hard linebreak. Due to the limitations of the TeX input processor, hard linebreaks would be ignored if we typed them directly into the document.tex document.

Hello world!  
_Foo_ bar!

Next, invoke LuaTeX from the terminal:

  \emph{(A forced linebreak)}%
  \par
}
\starttext
\markdownInput{example.md}
\stoptext

Using a text editor, create a text document named example.md with the following content. Note the two spaces at the end of the first line, which specify a hard linebreak. Due to the limitations of the TeX input processor, hard linebreaks would be ignored if we typed them directly into the document.tex document.

Hello world!  
_Foo_ bar!

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Hello world!

(A forced linebreak)

Foo bar!

2.3.1.3 Ellipsis Renderer

2.3.1.9 Content Block Renderers

The \markdownRendererContentBlock macro represents an iA Writer content block. It receives four arguments: the local file or online image filename extension cast to the lower case, the fully escaped uri that can be directly typeset, the raw uri that can be used outside typesetting, and the title of the content block.

The \markdownRendererContentBlockOnlineImage macro represents an iA Writer online image content block. The macro receives the same arguments as \markdownRendererContentBlock.

The \markdownRendererContentBlockCode macro represents an iA Writer content block that was recognized as a file in a known programming language by its filename extension s. If any markdown-languages.json file found by contains a record (k, v), then a non-online-image content block with the filename extension s, s:lower() = k is considered to be in a known programming language v. The macro receives five arguments: the local file name extension s cast to the lower case, the language v, the fully escaped uri that can be directly typeset, the raw uri that can be used outside typesetting, and the title of the content block.

Note that you will need to place place a markdown-languages.json file inside your working directory or inside your local TeX directory structure. In this file, you will define a mapping between filename extensions and the language names recognized by your favorite syntax highlighter; there may exist other creative uses beside syntax highlighting. The Languages.json file provided by Anton Sotkov is a good starting point.

Plain TeX Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\def\markdownOptionContentBlocks{true}
\def\markdownRendererContentBlock#1#2#3#4{%

Plain TeX Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\def\markdownOptionFootnotes{true}
\def\markdownRendererFootnote#1{ (and \lowercase{#1})}
\markdownBegin
This is some text[^1] and this is some other text[^2].

 [^1]: this is a footnote

 [^2]: this is some other footnote
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

This is some text (and this is a footnote) and this is some other text (and this is some other footnote).

2.3.1.19 Parenthesized Citations Renderer

The \markdownRendererCite macro represents a string of one or more parenthetical citations. This macro will only be produced, when the citations option is true. The macro receives the parameter {number of citations} followed by {prenote}{postnote}{name} repeated ⟨number of citations⟩ times. The ⟨suppress author⟩ parameter is either the token -, when the author’s name is to be suppressed, or + otherwise.

LaTeX Example

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage[citations]{markdown}
\newcount\citationsCounter
\newcount\citationsTotal
\makeatletter
\def\citations#1#2#3#4{%
  a parenthesized citation \emph{#4}
  \advance\citationsCounter by 1\relax
  \ifx\relax#2\relax
    \ifx\relax#3\relax\else
      with a postfix \emph{#3}%
    \fi
  \else
    with a prefix \emph{#2}%
    \ifx\relax#3\relax\else
      \ and a postfix \emph{#3}%
    \fi
  \fi
  \ifnum\citationsCounter>\citationsTotal\relax
    .%
    \expandafter\@gobble
  \else
    , and

2.3.1.21 Table Renderer

The \markdownRendererTable macro represents a table. This macro will only be produced, when the pipeTables option is true. The macro receives the parameters {caption}{number of rows}{number of columns} followed by {alignments} and then by {row} repeated ⟨number of rows⟩ times, where ⟨row⟩ is {column} repeated ⟨number of columns⟩ times, ⟨alignments⟩ is ⟨alignment⟩ repeated ⟨number of columns⟩ times, and ⟨alignment⟩ is one of the following:

LaTeX Example

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage[pipeTables, tableCaptions]{markdown}
\newcount\rowCounter
\newcount\columnCounter
\makeatletter
\def\processRow#1{%
  \columnCounter=1%
  \ifnum\rowCounter=0\relax
    As for the alignment,
  \else
    In row \the\rowCounter,
  \fi
  \processColumn#1
  \advance\rowCounter by 1\relax
  \ifnum\rowCounter>\rowTotal\relax
    \expandafter\@gobble
  \fi\processRow}%
\def\processColumn#1{%
  column number \the\columnCounter{}
  \ifnum\rowCounter=0\relax
    \if#1d{}has default alignment\fi
    \if#1l{}is left-aligned\fi
    \if#1c{}is centered\fi
    \if#1r{}is right-aligned\fi
  \else
    says \emph{#1}%
  \fi
  \advance\columnCounter by 1\relax
  \ifnum\columnCounter<\columnTotal\relax, \fi
  \ifnum\columnCounter=\columnTotal\relax, and \fi
  \ifnum\columnCounter>\columnTotal\relax
    .\expandafter\@gobble
  \fi\processColumn}%
\makeatother
\markdownSetup{
  renderers = {
    table = {%
      This is a table with caption \emph{#1} that is #3 colums wide
      and #2 rows long.
      \rowCounter=0%
      \def\rowTotal{#2}%
      \def\columnTotal{#3}%
      \processRow
    },
  },
}
\begin{document}
\begin{markdown}
| Right | Left | Default | Center |
|------:|:-----|---------|:------:|
|   12  |  12  |    12   |    12  |
|  123  |  123 |   123   |   123  |

  : Demonstration of pipe table syntax
\end{markdown}
\end{document}
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

This is a table with caption Demonstration of pipe table syntax that is 4 colums wide and 4 rows long. As for the alignment, column number 1 is right-aligned, column number 2 is left-aligned, column number 3 has default alignment, and column number 4 is centered. In row 1, column number 1 says Right, column number 2 says Left, column number 3 says Default, and column number 4 says Center. In row 2, column number 1 says 12, column number 2 says 12, column number 3 says 12, and column number 4 says 12. In row 3, column number 1 says 123, column number 2 says 123, column number 3 says 123, and column number 4 says 123. In row 4, column number 1 says 1, column number 2 says 1, column number 3 says 1, and column number 4 says 1.

2.3.2 Token Renderer Prototypes

By default, token renderers point to package-defined TeX macros, further referred to as prototypes, which provide useful default definitions.

Plain TeX Example

Using a text editor, create a text document named document.tex with the following content:

\input markdown
\def\markdownRendererTildePrototype{%
  Packages can specify token renderer prototypes.%
}
\markdownBegin
~
\markdownEnd

\def\markdownRendererTilde{%
  User-defined token renderers take precedence.%
}
\markdownBegin
~
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Packages can specify token renderer prototypes.

User-defined token renderers take precedence.

LaTeX Example

Using a text editor, create a text document named document.tex with the following content:

\documentclass{article}
\usepackage{markdown}
\markdownSetup{
  rendererPrototypes = {
    tilde = {Packages can specify token renderer prototypes.},
  },
}
\begin{document}
\begin{markdown}
~
\end{markdown}

\begin{markdown*}{
  renderers = {
    tilde = {User-defined token renderers take precedence.},
  },
}
~
\end{markdown*}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain the following text:

Packages can specify token renderer prototypes.

User-defined token renderers take precedence.

ConTeXt Example

Using a text editor, create a text document named document.tex with the following content:

\usemodule[t][markdown]
\def\markdownRendererTildePrototype{%
  Packages can specify token renderer prototypes.%
}
\starttext
\startmarkdown
~
\stopmarkdown

\def\markdownRendererTilde{%
  User-defined token renderers take precedence.%
}
\startmarkdown
~
\stopmarkdown
\stoptext

Next, invoke LuaTeX from the terminal:

context document.tex

A PDF document named document.pdf should be produced and contain the following text:

Packages can specify token renderer prototypes.

User-defined token renderers take precedence.


  1. Here is the footnote.

  2. Here’s one with multiple blocks.

    Subsequent paragraphs are indented to show that they belong to the previous footnote.

    { some.code }

    The whole paragraph can be indented, or just the first line. In this way, multi-paragraph footnotes work like multi-paragraph list items.
