Markdown Package User Manual

Vít Starý Novotný, Andrej Genčur

3.7.0-0-g98dece19 2024-08-30

1 Introduction

The Markdown package converts CommonMark markup to T_eX commands. The functionality is provided both as a Lua module and as plain T_eX, L^aT_eX, and ConT_eXt macro packages that can be used to directly typeset T_eX documents containing markdown markup. Unlike other converters, the Markdown package does not require any external programs, and 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 either our official Docker image, which contains the latest development version of the Markdown package, or a T_eX distribution: T_eX Live ≥ 2022 is known to work with the current version of the Markdown package and so are recent versions of MikT_eX. If you are using an older, incomplete, or atypical T_eX distribution, please consult the technical documentation for a detailed list of requirements.

1.2 Installation

If the Markdown package is not included in your T_eX distribution, you will need to install it.

From Releases, download an archive markdown.zip for this version of the Markdown package (3.7.0) or a different version that you wish to install. Then, unzip the archive. If you downloaded an archive for a different version of the Markdown package, you should now locate a file named markdown.html with the user manual for that version, open it, and follow the installation steps in it rather than the steps from this manual.

Alternatively, download the package from the repository using Git, enter the directory named markdown and run the make base command using GNU Make:

git clone https://github.com/witiko/markdown
cd markdown
make base

Either of the two abovelisted approaches should produce the following files:

markdown.lua and markdown-parser.lua: The Lua module
libraries/markdown-tinyyaml.lua: An external library for reading yaml
markdown-cli.lua: The Lua command-line interface
markdown.tex: The plain T_eX macro package
markdown.sty: The L^aT_eX package
markdownthemewitiko_dot.sty: The witiko/dot L^aT_eX theme
markdownthemewitiko_graphicx_http.sty: The witiko/graphicx/http L^aT_eX theme
markdownthemewitiko_tilde.tex: The witiko/tilde theme
markdownthemewitiko_markdown_defaults.tex, markdownthemewitiko_markdown_defaults.sty, and t-markdownthemewitiko_markdown_defaults.tex: The witiko/markdown/defaults theme
t-markdown.tex: The ConT_eXt module

1.2.1 Local Installation

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

⟨TEXMF⟩/tex/luatex/markdown/markdown.lua
⟨TEXMF⟩/tex/luatex/markdown/markdown-parser.lua
⟨TEXMF⟩/tex/luatex/markdown/markdown-tinyyaml.lua
⟨TEXMF⟩/scripts/markdown/markdown-cli.lua
⟨TEXMF⟩/tex/generic/markdown/markdown.tex
⟨TEXMF⟩/tex/generic/markdown/markdownthemewitiko_tilde.tex
⟨TEXMF⟩/tex/generic/markdown/markdownthemewitiko_markdown_defaults.tex
⟨TEXMF⟩/tex/latex/markdown/markdown.sty
⟨TEXMF⟩/tex/latex/markdown/markdownthemewitiko_dot.sty
⟨TEXMF⟩/tex/latex/markdown/markdownthemewitiko_graphicx_http.sty
⟨TEXMF⟩/tex/latex/markdown/markdownthemewitiko_markdown_defaults.sty
⟨TEXMF⟩/tex/context/third/markdown/t-markdown.tex
⟨TEXMF⟩/tex/context/third/markdown/t-markdownthemewitiko_markdown_defaults.tex

where ⟨TEXMF⟩ corresponds to a root of your T_eX 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 T_eX distribution.

1.2.2 Portable Installation

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

This is where the individual files should be placed:

./markdown.lua
./markdown-parser.lua
./markdown-tinyyaml.lua
./markdown-cli.lua
./markdown/markdown.tex
./markdown.sty
./t-markdown.tex
./markdownthemewitiko_dot.sty
./markdownthemewitiko_graphicx_http.sty
./markdownthemewitiko_tilde.tex
./markdownthemewitiko_markdown_defaults.tex
./markdownthemewitiko_markdown_defaults.sty
./t-markdownthemewitiko_markdown_defaults.tex

The file markdown.tex must be placed in a directory named markdown.

1.3 First Document

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

If you are using our official Docker image, you need to prefix all commands in this section with docker run --rm -v "$PWD"/workdir:/workdir -w /workdir witiko/markdown. For example, instead of luatex document.tex, you would execute the following command:

docker run --rm -v "$PWD"/workdir:/workdir -w /workdir witiko/markdown \
  luatex document.tex

1.3.1 Using Lua

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

\input markdown
\begingroup
\catcode`\%=12
\catcode`\#=12
\input hello
\endgroup
\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 -a 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 T_eX

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!”

Instead of LuaTeX, you may also use pdfTeX:

pdftex --shell-escape document.tex

This should also produce a PDF document named document.pdf with the same content.

Instead of writing your markdown document between \markdownBegin and \markdownEnd, you can also include markdown documents using the \markdownInput macro, similarly to how you might use the \input TeX primitive to include T_eX documents.

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

Hello *world*!

Create also a text document named document.tex with the following content:

\input markdown
\markdownInput{hello.md}
\bye

Next, invoke LuaTeX or pdfTeX from the terminal like in the previous example. A PDF document named document.pdf should be produced and contain the text “Hello world!”

1.3.3 Using L^aT_eX

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!”

Instead of LuaTeX, you may also use pdfTeX:

pdflatex --shell-escape document.tex

This should also produce a PDF document named document.pdf with the same content.

Instead of writing your markdown document between \begin{markdown} and \end{markdown}, you can also include markdown documents using the \markdownInput macro, similarly to how you might use the \input TeX primitive to include L^aT_eX documents.

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

Hello *world*!

Create also a text document named document.tex with the following content:

\documentclass{article}
\usepackage{markdown}
\begin{document}
\begin{markdown}
\markdownInput{hello.md}
\end{markdown}
\end{document}

Next, invoke LuaTeX or pdfTeX from the terminal like in the previous example. A PDF document named document.pdf should be produced and contain the text “Hello world!”

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-luatex.tex

A PDF document named latex-luatex.pdf should be produced. Open the text documents latex-luatex.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-luatex.tex

to see the effect of your changes.

1.3.4 Using ConT_eXt

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 --luatex document.tex

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

Instead of writing your markdown document between \startmarkdown and \stopmarkdown, you can also include markdown documents using the \inputmarkdown macro, similarly to how you might use the \input TeX primitive to include ConT_eXt documents.

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

Hello *world*!

Create also a text document named document.tex with the following content:

\usemodule[t][markdown]
\starttext
\inputmarkdown{hello.md}
\stoptext

Next, invoke LuaTeX from the terminal like in the previous example. A PDF document named document.pdf should be produced and contain the text “Hello world!”

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 --luatex 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 --luatex 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 L^aT_eX and ConT_eXt interfaces intended for the ordinary user.

2.1.1 Lua

The Lua programming language is what drives the conversion from markdown to T_eX in the Markdown package. Based on the Lunamark Lua library by John MacFarlane, the Lua implementation is largely independent on T_eX, 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 T_eX from within LuaT_eX documents and Lua scripts.

The markdown Lua module exposes the new(⟨options⟩) method, which creates a converter function from markdown to T_eX. 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
\begingroup
\catcode`\%=12
\catcode`\#=12
\input example
\endgroup
\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_nomath, convert_math, paragraph

input = [[$\sqrt{-1}$ *equals* $i$.]]
convert_nomath = markdown.new()
convert_math = markdown.new({texMathDollars = true})
paragraph = [[\par]]

print(
  convert_nomath(input) .. paragraph ..
  convert_math(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 $i$.

$\sqrt{- 1}$ 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_nomath, convert_math, paragraph

  input = [[$\string\sqrt{-1}$ *equals* $i$.]]
  convert_nomath = markdown.new()
  convert_math = markdown.new({texMathDollars = true})
  paragraph = [[\par]]

  tex.sprint(
    convert_nomath(input) .. paragraph ..
    convert_math(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 $i$.

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

In this case, we cannot use pdfTeX, because pdfTeX does not define the \directlua T_eX 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 T_eX 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
\begingroup
\catcode`\%=12
\catcode`\#=12
\input nomath
\par
\input math
\endgroup
\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 nomath.tex
texlua ⟨CLI pathname⟩ tex_math_dollars=true -- example.md math.tex
luatex document.tex

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

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

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

Invoking pdfTeX should have the same effect:

texlua ⟨CLI pathname⟩ -- example.md nomath.tex
texlua ⟨CLI pathname⟩ tex_math_dollars=true -- example.md math.tex
pdftex document.tex

2.1.2 Plain T_eX

The plain T_eX interface provides T_eX 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 T_eX. Instead, its goal is to provide high-level typesetting capabilities.

The plain T_eX interface accepts the same options as the markdown Lua module, in addition to its own options, but now the options are specified as T_eX 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\markdownOptionTexMathDollars{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 $i$.

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

Invoking pdfTeX should have the same effect:

pdftex --shell-escape document.tex

2.1.3 L^aT_eX

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

The L^aT_eX interface accepts the same options as the plain T_eX 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* L^aT_eX 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}[texMathDollars]
$\sqrt{-1}$ *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 $i$.

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

Invoking pdfTeX should have the same effect:

pdflatex --shell-escape document.tex

2.1.4 ConT_eXt

The ConT_eXt interface provides the same level of functionality as the plain T_eX interface by using the plain T_eX interface behind the scenes. Unlike the plain T_eX interface, the ConT_eXt interface uses familiar ConT_eXt idioms as syntactic sugar.

The ConT_eXt interface accepts the same options as the plain T_eX 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

\setupmarkdown[texmathdollars = yes]
\startmarkdown
$\sqrt{-1}$ *equals* $i$.
\stopmarkdown

\stoptext

Next, invoke LuaTeX from the terminal:

context --luatex document.tex

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

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

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

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 T_eX. They are supported by all interfaces of the Markdown package starting with the low-level Lua interfaces and all the way up to the L^aT_eX and ConT_eXt interfaces.

2.2.1.1 Option `eagerCache`

eagerCache (default value: true)

true

Converted markdown documents will be cached in cacheDir. This can be useful for post-processing the converted documents and for recovering historical versions of the documents from the cache. Furthermore, it can also significantly improve the processing speed for documents that require multiple compilation runs, since each markdown document is only converted once. However, it also produces a large number of auxiliary files on the disk and obscures the output of the Lua command-line interface when it is used for plumbing.

This behavior will always be used if the finalizeCache option is enabled.

false

Converted markdown documents will not be cached. This decreases the number of auxiliary files that we produce and makes it easier to use the Lua command-line interface for plumbing. However, it makes it impossible to post-process the converted documents and recover historical versions of the documents from the cache. Furthermore, it can significantly reduce the processing speed for documents that require multiple compilation runs, since each markdown document is converted multiple times needlessly.

This behavior will only be used when the finalizeCache option is disabled.

Lua CLI Example

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

Hello *world*!

Next, invoke LuaTeX from the terminal with the eagerCache option disabled:

texlua ⟨CLI pathname⟩ eagerCache=false -- hello.md hello.tex

A T_eX document named hello.tex should be produced and contain the following code:

Hello \markdownRendererEmphasis{world}!\relax

Invoke LuaTeX from the terminal again, this time with the eagerCache option enabled:

texlua ⟨CLI pathname⟩ eagerCache=true -- hello.md hello.tex

A T_eX document named hello.tex should be produced and contain the following code:

\input ./⟨hash⟩.md.tex\relax

Additionally, a T_eX document named ⟨hash⟩.md.tex should be produced and contain the following code:

Hello \markdownRendererEmphasis{world}!\relax

2.2.1.2 Option `singletonCache`

singletonCache (default value: true)

true

Conversion functions produced by the function new(options) will be cached in an LRU cache of size 1 keyed by options. This is more time- and space-efficient than always producing a new conversion function but may expose bugs related to the idempotence of conversion functions.

This has been the default behavior since version 3.0.0 of the Markdown package.

false

Every call to the function new(options) will produce a new conversion function that will not be cached. This is slower than caching conversion functions and may expose bugs related to memory leaks in the creation of conversion functions, see also #226 (comment).

This was the default behavior until version 3.0.0 of the Markdown package.

Lua Module Example

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

\input markdown
\begingroup
\catcode`\%=12
\catcode`\#=12
\directlua{
  local markdown = require("markdown")
  local convert1 = markdown.new({})
  local convert2 = markdown.new({singletonCache=false})
  local convert3 = markdown.new({singletonCache=true})
  local newline = [[^^J^^J]]
  tex.print(tostring(convert1) .. ", ")
  tex.print(tostring(convert2) .. ", ")
  tex.print(tostring(convert3))
}
\endgroup
\bye

Then, invoke LuaTeX from the terminal:

luatex document.tex

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

function: 0x1a4a038, function: 0x1a52b18, function: 0x1a4a038

As you can see, the caching causes convert1 and convert3 to be the same conversion function.

2.2.1.3 Option `unicodeNormalization`

unicodeNormalization (default value: true)

true: Markdown documents will be normalized using one of the four Unicode normalization forms before conversion. The Unicode normalization norm used is determined by option unicodeNormalizationForm.

false: Markdown documents will not be Unicode-normalized before conversion.

2.2.1.4 Option `unicodeNormalizationForm`

unicodeNormalizationForm (default value: nfc)

nfc: When option unicodeNormalization has been enabled, markdown documents will be normalized using Unicode Normalization Form C (NFC) before conversion.

nfd: When option unicodeNormalization has been enabled, markdown documents will be normalized using Unicode Normalization Form D (NFD) before conversion.

nfkc: When option unicodeNormalization has been enabled, markdown documents will be normalized using Unicode Normalization Form KC (NFKC) before conversion.

nfkd: When option unicodeNormalization has been enabled, markdown documents will be normalized using Unicode Normalization Form KD (NFKD) before conversion.

2.2.1.5 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 T_eX 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
\begingroup
\catcode`\%=12
\catcode`\#=12
\directlua{
  local markdown = require("markdown")
  local convert = markdown.new({cacheDir = "cache"})
  local input = "Hello *world*!"
  tex.sprint(convert(input)) }
\endgroup
\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
\begingroup
\catcode`\%=12
\catcode`\#=12
\input hello
\endgroup
\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

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 T_eX 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

L^aT_eX Example

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

\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

ConT_eXt Example

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

\usemodule[t][markdown]
\setupmarkdown[cacheDir = cache]
\starttext
\startmarkdown
Hello *world*!
\stopmarkdown
\stoptext

Next, invoke LuaTeX from the terminal:

context --luatex document.tex

2.2.1.6 Option `contentBlocksLanguageMap`

contentBlocksLanguageMap (default value: "markdown-languages.json"): The filename of the JSON file that maps filename extensions to programming language names in the iA Writer content blocks when the contentBlocks option is enabled.

L^aT_eX Example

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

Name,Surname,Born
Albert,Einstein,1879
Marie,Curie,1867
Thomas,Edison,1847

Create also a text document named language-map.json with the following content:

{
  "tex": "LaTeX"
}

Create also a text document named code.tex with the following content:

This is an example code listing in \LaTeX.

Create also a text document named part.md with the following content:

This is a *transcluded markdown document*.

Create also a text document named document.tex with the following content:

\documentclass{article}
\usepackage{minted}
\usepackage[contentBlocks]{markdown}
\markdownSetup{
  contentBlocksLanguageMap = {language-map.json},
}
\begin{document}
\begin{markdown}
/table.csv  (An example table)
/code.tex   (An example code listing)
/part.md    (A file transclusion example)
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex --shell-escape document.tex

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

Name Surname Born

Albert Einstein 1879

Marie Curie 1867

Thomas Edison 1847

Table 1: An example table
This is an example code listing in \LaTeX.
This is a transcluded markdown document.

Name	Surname	Born
Albert	Einstein	1879
Marie	Curie	1867
Thomas	Edison	1847

ConT_eXt Example

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

Name,Surname,Born

Create also a text document named language-map.json with the following content:

{
  "tex": "ConTeXt"
}

Create also a text document named code.tex with the following content:

This is an example code listing in \ConTeXt.

Create also a text document named part.md with the following content:

Next, invoke LuaTeX from the terminal:

context --luatex document.tex

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

Name Surname Born

Albert Einstein 1879

2.2.1.7 Option `debugExtensionsFileName`

debugExtensionsFileName (default value: "debug-extensions.json"): The filename of the JSON file that will be produced when the debugExtensions option is enabled. This file will contain the extensible subset of the peg grammar of markdown after built-in syntax extensions (see options citations, contentBlocks, definitionLists, etc.) and user-defined syntax extensions (see option extensions) have been applied.

2.2.1.8 Option `frozenCacheFileName`

frozenCacheFileName (default value: "frozenCache.tex")

A path to an output file (frozen cache) that will be created when the finalizeCache option is enabled and will contain a mapping between an enumeration of markdown documents and their auxiliary cache files.

The frozen cache makes it possible to later typeset a plain T_eX document that contains markdown documents without invoking Lua using the frozenCache plain T_eX option. As a result, the plain T_eX document becomes more portable, but further changes in the order and the content of markdown documents will not be reflected.

Lua Module Example

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

\input markdown
\begingroup
\catcode`\%=12
\catcode`\#=12
\directlua{
  local markdown = require("markdown")
  local convert = markdown.new({finalizeCache = true, frozenCacheFileName = "cache.tex"})
  local input = "Hello *world*!"
  tex.sprint(convert(input)) }
\endgroup
\bye

Then, invoke LuaTeX from the terminal:

luatex document.tex

A PDF document named document.pdf should be produced and contain the text “Hello world!” A frozen cache will also be produced in the cache.tex output file as we requested using the finalizeCache and frozenCacheFileName options.

Lua CLI Example

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

\input markdown
\begingroup
\catcode`\%=12
\catcode`\#=12
\input hello
\endgroup
\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⟩ finalizeCache=true frozenCacheFileName=cache.tex -- hello.md hello.tex
luatex document.tex

Plain T_eX Example

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

\input markdown
\def\markdownOptionFinalizeCache{true}
\def\markdownOptionFrozenCacheFileName{cache.tex}
\markdownBegin
Hello *world*!
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

Next, create a new text document frozen-document.tex with the following content:

\input markdown
\def\markdownOptionFrozenCache{true}
\def\markdownOptionFrozenCacheFileName{cache.tex}
\markdownBegin
Hi *world*!
\markdownEnd
\bye

Last, invoke pdfTeX without shell access from the terminal:

pdftex -no-shell-escape frozen-document.tex

A PDF document named frozen-document.pdf should be produced and contain the text “Hello world!” Since we used the contents of the frozen cache using the \markdownOptionFrozenCache option, we were able to typeset the document without accessing the shell or invoking Lua, but the change in the content of the markdown document from “Hello world!” to “Hi world!” was not reflected.

L^aT_eX Example

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

\documentclass[finalizecache]{article}
\usepackage[frozenCacheFileName=cache.tex]{markdown}
\begin{document}
\begin{markdown}
Hello *world*!
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

Next, create a new text document frozen-document.tex with the following content:

\documentclass[frozencache]{article}
\usepackage[frozenCacheFileName=cache.tex]{markdown}
\begin{document}
\begin{markdown}
Hi *world*!
\end{markdown}
\end{document}

Last, invoke pdfTeX without shell access from the terminal:

pdflatex -no-shell-escape frozen-document.tex

A PDF document named frozen-document.pdf should be produced and contain the text “Hello world!” Since we used the contents of the frozen cache using the frozencache option, we were able to typeset the document without accessing the shell or invoking Lua, but the change in the content of the markdown document from “Hello world!” to “Hi world!” was not reflected.

Next, invoke LuaTeX from the terminal:

lualatex --shell-escape document.tex

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

Here is a special paragraph.

2.2.1.31 Option `finalizeCache`

finalizeCache (default value: false)

Whether an output file specified with the frozenCacheFileName option (frozen cache) that contains a mapping between an enumeration of markdown documents and their auxiliary cache files will be created.

Plain T_eX Example

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

\input markdown
\def\markdownOptionFinalizeCache{true}
\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 frozen cache will also be produced as we requested using the finalizeCache option.

Next, change the content of document.tex as follows:

\input markdown
\def\markdownOptionFrozenCache{true}
\markdownBegin
Hi *world*!
\markdownEnd
\bye

Last, invoke pdfTeX without shell access from the terminal:

pdftex -no-shell-escape document.tex

A new PDF document named document.pdf should be produced and contain the same text “Hello world!” Since we used the contents of the frozen cache using the \markdownOptionFrozenCache option, we were able to typeset the document without accessing the shell or invoking Lua, but the change in the content of the markdown document from “Hello world!” to “Hi world!” was not reflected.

L^aT_eX Example

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

\documentclass[finalizecache]{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!” A frozen cache will also be produced as we requested using the finalizecache option.

Next, change the content of document.tex as follows:

\documentclass[frozencache]{article}
\usepackage{markdown}
\begin{document}
\begin{markdown}
Hi *world*!
\end{markdown}
\end{document}

Last, invoke pdfTeX without shell access from the terminal:

pdflatex -no-shell-escape document.tex

ConT_eXt Example

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

\usemodule[t][markdown]
\setupmarkdown[finalizeCache = yes]
\starttext

Next, invoke LuaTeX from the terminal:

context --luatex document.tex

Next, change the content of document.tex as follows:

\usemodule[t][markdown]
\setupmarkdown[frozenCache = yes]
\starttext
\startmarkdown
Hi *world*!
\stopmarkdown
\stoptext

Last, invoke LuaTeX from the terminal:

context --luatex document.tex

2.2.1.32 Option `frozenCacheCounter`

frozenCacheCounter (default value: 0)

The number of the current markdown document that will be stored in an output file (frozen cache) when the finalizeCache is enabled. When the document number is 0, then a new frozen cache will be created. Otherwise, the frozen cache will be appended.

Each frozen cache entry will define a T_eX macro \markdownFrozenCache⟨number⟩ that will typeset markdown document number ⟨number⟩.

Lua Module Example

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

\input markdown
\begingroup
\catcode`\%=12
\catcode`\#=12
\directlua{
  local markdown = require("markdown")
  local firstConvert = markdown.new({finalizeCache = true, frozenCacheCounter = 0})
  local firstInput = "Hello"
  local secondConvert = markdown.new({finalizeCache = true, frozenCacheCounter = 1})
  local secondInput = "*world*!"
  tex.sprint(firstConvert(firstInput) .. [[ ]] .. secondConvert(secondInput)) }
\endgroup
\bye

Then, invoke LuaTeX from the terminal:

luatex document.tex

2.2.1.37 Option `hybrid`

hybrid (default value: false)

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

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

`$H_2 O$`{=tex} is a liquid.

To enable raw blocks, the fencedCode option must also be enabled:

Here is a mathematical formula:
``` {=tex}
\[distance[i] =
    \begin{dcases}
        a & b \\
        c & d
    \end{dcases}
\]
```

The rawAttribute option is a good alternative to the hybrid option. Unlike the hybrid option, which affects the entire document, the rawAttribute option allows you to isolate the parts of your documents that use TeX:

false: Disable the Pandoc raw attribute syntax extension.

L^aT_eX Example

2.2.1.49 Option `shiftHeadings`

shiftHeadings (default value: 0): All headings will be shifted by ⟨shift amount⟩, which can be both positive and negative. Headings will not be shifted beyond level 6 or below level 1. Instead, those headings will be shifted to level 6, when ⟨shift amount⟩ is positive, and to level 1, when ⟨shift amount⟩ is negative.

2.2.1.50 Option `slice`

slice (default value: ^ $)

Two space-separated selectors that specify the slice of a document that will be processed, whereas the remainder of the document will be ignored. The following selectors are recognized:

The circumflex (^) selects the beginning of a document.
The dollar sign ($) selects the end of a document.
^⟨identifier⟩ selects the beginning of a section or a fenced div with the HTML attribute #⟨identifier⟩.
$⟨identifier⟩ selects the end of a section with the HTML attribute #⟨identifier⟩.
⟨identifier⟩ corresponds to ^⟨identifier⟩ for the first selector and to $⟨identifier⟩ for the second selector.

Specifying only a single selector, ⟨identifier⟩, is equivalent to specifying the two selectors ⟨identifier⟩ ⟨identifier⟩, which is equivalent to ^⟨identifier⟩ $⟨identifier⟩, i.e. the entire section with the HTML attribute #⟨identifier⟩ will be selected.

2.2.2 Plain T_eX

Plain T_eX options control the communication between the T_eX interface and the markdown Lua module. They are supported by all higher-level interfaces of the Markdown package, i.e. the plain T_eX, L^aT_eX and ConT_eXt interfaces.

2.2.2.1 Setting Lua options from plain T_eX

As a rule of thumb, you can set all Lua options directly from plain T_eX. For example, to set the taskLists Lua option to true, you would include the following code in your plain T_eX document:

\def\markdownOptionTaskLists{true}

Alternatively, you can also set plain T_eX options using the \markdownSetup T_eX macro. For example, to set the taskLists Lua option to true, you would include the following code in your plain T_eX document:

\markdownSetup{taskLists = true}

2.2.2.2 Finalizing and Freezing the Cache

The markdownOptionFrozenCache option uses the mapping previously created by the Lua interface finalizeCache option, and uses it to typeset the plain T_eX document without invoking Lua. As a result, the plain T_eX document becomes more portable, but further changes in the order and the content of markdown documents will not be reflected. It defaults to false.

The standard usage of the finalizeCache and frozenCache options is as follows:

Remove the cacheDir cache directory with stale auxiliary cache files.
Enable the finalizeCache option.
Typeset the plain T_eX document to populate and finalize the cache.
Enable the frozenCache option.
Publish the source code of the plain T_eX document and the cacheDir directory.

For more information, see the examples for the finalizeCache option.

2.2.2.3 File and Directory Names

The plain T_eX interface provides the following commands that you can use to specify the location of temporary files produced during the conversion from Markdown to T_eX:

\markdownOptionInputTempFileName,
\markdownOptionOutputDir,
\markdownOptionCacheDir, and
\markdownOptionFrozenCacheFileName.

The \markdownOptionCacheDir and \markdownOptionFrozenCacheFileName commands correspond to the cacheDir and frozenCacheFileName Lua options.

Using a text editor, create a folder named output-directory and a text document named document.tex with the following content:

\input lmfonts
\input markdown
\def\markdownOptionInputTempFileName{temporary-input.md}
\def\markdownOptionOutputDir{output-directory}
\def\markdownOptionCacheDir{output-directory/cache-directory}
\def\markdownOptionEagerCache{true}
\def\markdownOptionFinalizeCache{true}
\def\markdownOptionFrozenCacheFileName{output-directory/cache-directory/frozen-cache.tex}
\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 T_eX. To produce the remaining temporary files, invoke pdfTeX from the terminal:

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

Text document named temporary-output.md should be produced in the folder named output-directory. The document will contain the input markdown document converted to T_eX.

2.2.2.4 No default token renderer prototypes

The Markdown package provides default definitions for token renderer prototypes using the witiko/markdown/defaults theme. Although these default definitions provide a useful starting point for authors, they use extra resources, especially with higher-level T_eX formats such as L^aT_eX and ConT_eXt. Furthermore, the default definitions may change at any time, which may pose a problem for maintainers of Markdown themes and templates who may require a stable output.

The markdownOptionPlain macro specifies whether higher-level T_eX formats should only use the plain T_eX default definitions or whether they should also use the format-specific default definitions. Whereas plain T_eX default definitions only provide definitions for simple elements such as emphasis, strong emphasis, and paragraph separators, format-specific default definitions add support for more complex elements such as lists, tables, and citations. On the flip side, plain T_eX default definitions load no extra resources and are rather stable, whereas format-specific default definitions load extra resources and are subject to a more rapid change.

Here is how you would enable the macro in a L^aT_eX document:

\usepackage[plain]{markdown}

Here is how you would enable the macro in a ConT_eXt document:

\def\markdownOptionPlain{true}
\usemodule[t][markdown]

The macro must be set before or during the loading of the package. Setting the macro after loading the package has no effect.

The markdownOptionNoDefaults macro specifies whether we should prevent the loading of default definitions or not. This is useful in contexts, where we want to have total control over how all elements are rendered.

Here is how you would enable the macro in a L^aT_eX document:

\usepackage[noDefaults]{markdown}

Here is how you would enable the macro in a ConT_eXt document:

\def\markdownOptionNoDefaults{true}
\usemodule[t][markdown]

The macro must be set before or during the loading of the package. Setting the macro after loading the package has no effect.

2.2.2.5 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 T_eX document. This enables the use of markdown when writing T_eX package documentation using the Doc L^aT_eX package by Frank Mittelbach. The recognized values of the macro are true (discard) and false (retain). It defaults to false.

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!”

2.2.3 Themes

User-defined themes for the Markdown package provide a domain-specific interpretation of Markdown tokens. Themes allow the authors to achieve a specific look and other high-level goals without low-level programming.

Built-in plain T_eX themes provided with the Markdown package include:

witiko/tilde: A theme that makes tilde (~) always typeset the non-breaking space even when the hybrid Lua option is disabled.

Plain T_eX Example

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

\input markdown
\markdownSetup{import=witiko/tilde}
\markdownBegin
Bartel~Leendert van~der~Waerden
\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, where the middot (·) denotes a non-breaking space:

Bartel·Leendert van·der·Waerden

witiko/markdown/defaults: A plain T_eX theme with the default definitions of token renderer prototypes for plain T_eX. This theme is loaded automatically together with the package and explicitly loading it has no effect.

2.2.4 Snippets

User-defined themes provide global control over high-level goals. However, it is often desirable to change only some local aspects of a document. Snippets provide syntactic sugar for defining and invoking various options locally.

Here is how we can use snippets to store options and invoke them later in L^aT_eX:

\markdownSetupSnippet{romanNumerals}{
  renderers = {
      olItemWithNumber = {%
          \item[\romannumeral#1\relax.]%
      },
  },
}
\begin{markdown}

The following ordered list will be preceded by arabic numerals:

1. wahid
2. aithnayn

\end{markdown}
\begin{markdown}[snippet=romanNumerals]

The following ordered list will be preceded by roman numerals:

3. tres
4. quattuor

\end{markdown}

If the romanNumerals snippet were defined in the jdoe/lists theme, we could import the jdoe/lists theme and use the qualified name jdoe/lists/romanNumerals to invoke the snippet:

\markdownSetup{import=jdoe/lists}
\begin{markdown}[snippet=jdoe/lists/romanNumerals]

The following ordered list will be preceded by roman numerals:

3. tres
4. quattuor

\end{markdown}

Alternatively, we can use the extended variant of the import L^aT_eX option that allows us to import the romanNumerals snippet to the current namespace for easier access:

\markdownSetup{
  import = {
    jdoe/lists = romanNumerals,
  },
}
\begin{markdown}[snippet=romanNumerals]

The following ordered list will be preceded by roman numerals:

3. tres
4. quattuor

\end{markdown}

Furthermore, we can also specify the name of the snippet in the current namespace, which can be different from the name of the snippet in the jdoe/lists theme. For example, we can make the snippet jdoe/lists/romanNumerals available under the name roman.

\markdownSetup{
  import = {
    jdoe/lists = romanNumerals as roman,
  },
}
\begin{markdown}[snippet=roman]

The following ordered list will be preceded by roman numerals:

3. tres
4. quattuor

\end{markdown}

Several themes and/or snippets can be loaded at once using the extended variant of the import L^aT_eX option:

\markdownSetup{
  import = {
    jdoe/longpackagename/lists = {
      arabic as arabic1,
      roman,
      alphabetic,
    },
    jdoe/anotherlongpackagename/lists = {
      arabic as arabic2,
    },
    jdoe/yetanotherlongpackagename,
  },
}

2.2.5 L^aT_eX

L^aT_eX options allow us to disable the redefinition of the default renderer prototypes from plain T_eX, load user-defined themes, and invoke user-defined set-up snippets.

2.2.5.1 Setting Lua and plain T_eX options from L^aT_eX

As a rule of thumb, we can set all Lua options directly from L^aT_eX. For example, to set the taskLists Lua option to true, we would include the following code in our L^aT_eX document:

\markdownSetup{
  taskLists = true,
}

We can also set all plain T_eX options directly from L^aT_eX. For example, to set the \markdownOptionInputTempFileName plain T_eX option to helper-script.lua, we would include the following code in our L^aT_eX document:

\markdownSetup{
  inputTempFileName = temporary-input.md,
}

2.2.6 Themes

In L^aT_eX, we expand on the concept of themes by allowing a theme to be a full-blown L^aT_eX package. Specifically, the key-values theme=⟨theme name⟩ and import=⟨theme name⟩ load a L^aT_eX package named markdowntheme⟨munged theme name⟩.sty if it exists and a T_eX document named markdowntheme\meta{munged theme name}.tex otherwise.

Having the Markdown package automatically load either the generic .tex theme file or the L^aT_eX-specific .sty theme file allows developers to have a single theme file, when the theme is small or the difference between T_eX formats is unimportant, and scale up to separate theme files native to different T_eX formats for large multi-format themes, where different code is needed for different T_eX formats. To enable code reuse, developers can load the .tex theme file from the .sty theme file using the markdownLoadPlainTeXTheme macro.

For example, to load themes named witiko/beamer/MU and witiko/dot, you would use the following code in the preamble of your document:

\usepackage[
  import=witiko/beamer/MU,
  import=witiko/dot,
]{markdown}

Due to limitations of L^aT_eX, themes may not be loaded after the beginning of a L^aT_eX document.

Built-in L^aT_eX themes provided with the Markdown package include:

witiko/dot: A theme that typesets fenced code blocks with the dot … infostring as images of directed graphs rendered by the Graphviz tools. The right tail of the infostring is used as the image title. The theme requires a Unix-like operating system with GNU Diffutils and Graphviz installed. The theme also requires shell access unless the frozenCache plain T_eX option is enabled.

L^aT_eX Example

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

\documentclass{article}
\usepackage[import=witiko/dot]{markdown}
\setkeys{Gin}{
  width=\columnwidth,
  height=0.65\paperheight,
  keepaspectratio}
\begin{document}
\begin{markdown}
``` dot Various formats of mathemathical formulae
digraph tree {
  margin = 0;
  rankdir = "LR";

  latex -> pmml;
  latex -> cmml;
  pmml -> slt;
  cmml -> opt;
  cmml -> prefix;
  cmml -> infix;
  pmml -> mterms [style=dashed];
  cmml -> mterms;

  latex [label = "LaTeX"];
  pmml [label = "Presentation MathML"];
  cmml [label = "Content MathML"];
  slt [label = "Symbol Layout Tree"];
  opt [label = "Operator Tree"];
  prefix [label = "Prefix"];
  infix [label = "Infix"];
  mterms [label = "M-Terms"];
}
```
\end{markdown}
\end{document}

Next, invoke LuaTeX from the terminal:

lualatex document.tex

A PDF document named document.pdf should be produced and contain a drawing of a directed graph similar to Figure 1 from the following conference article:

NOVOTNÝ, Vít, Petr SOJKA, Michal ŠTEFÁNIK and Dávid LUPTÁK. Three is Better than One: Ensembling Math Information Retrieval Systems. CEUR Workshop Proceedings. Thessaloniki, Greece: M. Jeusfeld c/o Redaktion Sun SITE, Informatik V, RWTH Aachen., 2020, vol. 2020, No 2696, p. 1-30. ISSN 1613-0073. http://ceur-ws.org/Vol-2696/paper_235.pdf

witiko/graphicx/http: A theme that adds support for downloading images whose URL has the http or https protocol. The theme requires the catchfile L^aT_eX package and a Unix-like operating system with GNU Coreutils md5sum and either GNU Wget or cURL installed. The theme also requires shell access unless the frozenCache plain T_eX option is enabled.

L^aT_eX Example

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

\documentclass{article}
\usepackage[import=witiko/graphicx/http]{markdown}
\begin{document}
\begin{markdown}
![img](https://github.com/witiko/markdown/raw/main/markdown.png
       "The banner of the Markdown package")
\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 image:

witiko/markdown/defaults: A L^aT_eX theme with the default definitions of token renderer prototypes for plain T_eX. This theme is loaded automatically together with the package and explicitly loading it has no effect.

2.2.7 Themes

In ConT_eXt, we expand on the concept of themes by allowing a theme to be a full-blown ConT_eXt module. Specifically, the key-values theme=⟨theme name⟩ and import=⟨theme name⟩ load a ConT_eXt module named t-markdowntheme⟨munged theme name⟩.tex if it exists and a T_eX document named markdowntheme\meta{munged theme name}.tex otherwise.

Having the Markdown package automatically load either the generic .tex theme file or the ConT_eXt-specific t-*.tex theme file allows developers to have a single theme file, when the theme is small or the difference between T_eX formats is unimportant, and scale up to separate theme files native to different T_eX formats for large multi-format themes, where different code is needed for different T_eX formats. To enable code reuse, developers can load the .tex theme file from the t-*.tex theme file using the markdownLoadPlainTeXTheme macro.

For example, to load a theme named witiko/tilde in your document:

\usemodule[t][markdown]
\setupmarkdown[import=witiko/tilde]

Built-in ConT_eXt themes provided with the Markdown package include:

witiko/markdown/defaults: A ConT_eXt theme with the default definitions of token renderer prototypes for plain T_eX. This theme is loaded automatically together with the package and explicitly loading it has no effect.

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 T_eX. Instead of reducing T_eX 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 T_eX macros, which render markdown tokens. In this section, I will describe the individual token renderers.

2.3.1.1 Attribute Renderers

The following macros are only produced, when at least one of the following options for markdown attributes on different elements is enabled:

autoIdentifiers
fencedCodeAttributes
gfmAutoIdentifiers
headerAttributes
inlineCodeAttributes
linkAttributes

markdownRendererAttributeIdentifier represents the ⟨identifier⟩ of a markdown element (id="⟨identifier⟩" in HTML and #⟨identifier⟩ in markdown attributes). The macro receives a single attribute that corresponds to the ⟨identifier⟩.

markdownRendererAttributeClassName represents the ⟨class name⟩ of a markdown element (class="⟨class name⟩ …" in HTML and .⟨class name⟩ in markdown attributes). The macro receives a single attribute that corresponds to the ⟨class name⟩.

markdownRendererAttributeKeyValue represents a HTML attribute in the form ⟨key⟩=⟨value⟩ that is neither an identifier nor a class name. The macro receives two attributes that correspond to the ⟨key⟩ and the ⟨value⟩, respectively.

L^aT_eX Example

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

\documentclass{article}
\usepackage[headerAttributes, underscores=false]{markdown}
\markdownSetup{
  renderers = {
    attributeIdentifier = {%
      \par
      \emph{(Identifier: #1)}
      \par
    },
    attributeClassName = {%
      \par
      \emph{(Class name: #1)}
      \par
    },
    attributeKeyValue = {%
      \par
      \emph{(Key: #1, Value: #2)}
      \par
    },
  },
}
\begin{document}
\begin{markdown}

# First top-level heading {jane=doe}

## A subheading {#identifier}

# Second top-level heading {.class_name}

\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:

First top-level heading

(Key: Jane, Value: Doe)

A subheading

(Identifier: identifier)

Second top-level heading

(Class name: class_name)

2.3.1.2 Block Quote Renderers

The markdownRendererBlockQuoteBegin macro represents the beginning of a block quote. The macro receives no arguments.

The markdownRendererBlockQuoteEnd macro represents the end of a block quote. The macro receives no arguments.

Plain T_eX Example

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

\input markdown
\def\markdownRendererBlockQuoteBegin{%
  \begingroup
  \vskip\parindent
  \leftskip=2\parindent
  \parindent=0pt
}
\def\markdownRendererBlockQuoteEnd{%
  \par
  \vskip\parindent
  \endgroup
}
\markdownBegin
A quote from William Shakespeare's King Lear:

> This is the excellent foppery of the world that when we are
> sick in fortune---often the surfeit of our own behavior---we
> make guilty of our disasters the sun, the moon, and the
> stars [...]
\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:

2.3.1.3 Bracketed Spans Attribute Context Renderers

The following macros are only produced, when the bracketedSpans option is enabled.

The markdownRendererBracketedSpanAttributeContextBegin and markdownRendererBracketedSpanAttributeContextEnd macros represent the beginning and the end of a context in which the attributes of an inline bracketed span apply. The macros receive no arguments.

L^aT_eX Example

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

\documentclass{article}
\usepackage[bracketedSpans]{markdown}
\markdownSetup{
  renderers = {
    bracketedSpanAttributeContextBegin = {(},
    bracketedSpanAttributeContextEnd = {)},
  },
}
\begin{document}

2.3.1.5 Citation Renderers

The markdownRendererCite macro represents a string of one or more parenthetical citations. This macro will only be produced, when the citations option is enabled. The macro receives the parameter {⟨number of citations⟩} followed by ⟨suppress author⟩ {⟨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.

\documentclass{article}
\usepackage[citations]{markdown}
\newcount\citationsCounter
\newcount\citationsTotal
\makeatletter

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

This is a parenthesized citation abrahams90 with a prefix see and a postfix pp. 12, and a citation eijkhout91 with a postfix pp. 34.

The markdownRendererTextCite macro represents a string of one or more text citations. This macro will only be produced, when the citations option is enabled. The macro receives parameters in the same format as the markdownRendererCite macro.

L^aT_eX 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{%

\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 text citation abrahams90 with a postfix pp. 12, and a citation eijkhout91 with a prefix also.

2.3.1.6 Code Block Renderers

The markdownRendererInputVerbatim macro represents a code block. The macro receives a single argument that corresponds to the filename of a file containing the code block contents.

The markdownRendererInputFencedCode macro represents a fenced code block. This macro will only be produced, when the fencedCode option is enabled. The macro receives three arguments that correspond to the filename of a file containing the code block contents, the fully escaped code fence infostring that can be directly typeset, and the raw code fence infostring that can be used outside typesetting.

L^aT_eX Example

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

\documentclass{article}

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 kpathsea³ 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 T_eX 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 T_eX 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{%
  This is {\tt #2}, #4.

2.3.1.42 Tickbox Renderers

The macros named markdownRendererTickedBox, markdownRendererHalfTickedBox, and markdownRendererUntickedBox represent ticked and unticked boxes, respectively. These macros will either be produced, when the taskLists option is enabled, or when the Ballot Box with X (☒, U+2612), Hourglass (⌛, U+231B) or Ballot Box (☐, U+2610) Unicode characters are encountered in the markdown input, respectively.

L^aT_eX Example

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

\documentclass{article}
\usepackage[taskLists]{markdown}
\markdownSetup{
  renderers = {
    untickedBox = No,
    tickedBox = Yes,
  },
}
\begin{document}
\begin{markdown}
- [ ] you can't.
- [x] I can!
\end{markdown}
\end{document}

2.3.1.43 Warning and Error Renderers

The markdownRendererWarning and markdownRendererError macros represent warnings and errors produced by the markdown parser. Both macros receive a single parameter with the text of the warning or error.

2.3.1.44 YAML Metadata Renderers

The markdownRendererJekyllDataBegin macro represents the beginning of a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives no arguments.

The markdownRendererJekyllDataEnd macro represents the end of a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives no arguments.

The markdownRendererJekyllDataMappingBegin macro represents the beginning of a mapping in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives two arguments: the scalar key in the parent structure, cast to a string following yaml serialization rules, and the number of items in the mapping.

The markdownRendererJekyllDataMappingEnd macro represents the end of a mapping in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives no arguments.

The markdownRendererJekyllDataSequenceBegin macro represents the beginning of a sequence in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives two arguments: the scalar key in the parent structure, cast to a string following yaml serialization rules, and the number of items in the sequence.

The markdownRendererJekyllDataSequenceEnd macro represents the end of a sequence in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives no arguments.

The markdownRendererJekyllDataBoolean macro represents a boolean scalar value in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives two arguments: the scalar key in the parent structure, and the scalar value, both cast to a string following yaml serialization rules.

The markdownRendererJekyllDataNumber macro represents a numeric scalar value in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives two arguments: the scalar key in the parent structure, and the scalar value, both cast to a string following yaml serialization rules.

The markdownRendererJekyllDataTypographicString and markdownRendererJekyllDataProgrammaticString macros represent string scalar values in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives two arguments: the scalar key in the parent structure, cast to a string following yaml serialization rules, and the scalar value.

For each string scalar value, both macros are produced. Whereas markdownRendererJekyllDataTypographicString receives the scalar value after all markdown markup and special T_eX characters in the string have been replaced by T_eX macros, markdownRendererJekyllDataProgrammaticString receives the raw scalar value. Therefore, whereas the markdownRendererJekyllDataTypographicString macro is more appropriate for texts that are supposed to be typeset with T_eX, such as document titles, author names, or exam questions, the markdownRendererJekyllDataProgrammaticString macro is more appropriate for identifiers and other programmatic text that won’t be typeset by T_eX.

Before Markdown 3.7.0, the markdownRendererJekyllDataTypographicString macro was named markdownRendererJekyllDataString and the markdownRendererJekyllDataProgrammaticString macro was not produced. The markdownRendererJekyllDataString has been deprecated and will be removed in Markdown 4.0.0.

The markdownRendererJekyllDataEmpty macro represents an empty scalar value in a yaml document. This macro will only be produced when the jekyllData option is enabled. The macro receives one argument: the scalar key in the parent structure, cast to a string following yaml serialization rules.

Plain T_eX Example

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

\input markdown
\def\markdownOptionJekyllData{true}
\def\markdownRendererJekyllDataTypographicString#1#2{\gdef\name{#2}}
\def\markdownRendererJekyllDataNumber#1#2{\gdef\age{#2}}
\def\markdownRendererJekyllDataEnd{%
  \name{} is \age{} years old.}
\markdownBegin
---
name: Jane Doe
age:  99
---
\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:

Jane Doe is 99 years old.

\documentclass{article}
\usepackage[jekyllData]{markdown}
\markdownSetup{
  renderers = {
    jekyllDataTypographicString = {\gdef\name{#2}},
    jekyllDataNumber = {\gdef\age{#2}},
    jekyllDataEnd = {\name{} is \age{} years old.},
  }
}
\begin{document}

\begin{markdown}
---
name: Jane Doe
age:  99
---
\end{markdown}

2.3.2 Token Renderer Prototypes

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

Plain T_eX 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.

L^aT_eX Example

\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

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

Next, invoke LuaTeX from the terminal:

context --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.

2.3.2.1 YAML Metadata Renderer Prototypes

By default, the renderer prototypes for YAML metadata provide a high-level interface that can be programmed using the markdown/jekyllData key–values from the l3keys module of the L^aT_eX3 kernel.

Plain T_eX Example

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

\input markdown
\def\markdownOptionJekyllData{true}
\ExplSyntaxOn
\keys_define:nn
  { markdown/jekyllData }
  {
    name .code:n = { \gdef\name{#1} },
    age  .code:n = { \gdef\age{#1}  },
  }
\ExplSyntaxOff
\def\markdownRendererJekyllDataEnd{%
  \name{} is \age{} years old.}
\markdownBegin
---
name: Jane Doe
age:  99
---
\markdownEnd
\bye

Next, invoke LuaTeX from the terminal:

luatex document.tex

  {
    name .code:n = { \gdef\name{#1} },
    age  .code:n = { \gdef\age{#1}  },
  }
\ExplSyntaxOff
\def\markdownRendererJekyllDataEnd{%
