Markdown Package User Manual

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 convertors, 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 ≥ 2020 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 Markdown is not included in your T_eX distribution, you will need to install it.

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

Next, enter the directory named markdown and run the make base command using GNU Make:

cd markdown
make base

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:

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.

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*!"))

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:

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

luatex document.tex

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

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:

\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}

lualatex document.tex

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

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:

\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

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

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:

\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

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)
)

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

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

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

luatex document.tex

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

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* $i$.

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:

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

luatex document.tex

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

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}

lualatex document.tex

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

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.

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

context --luatex document.tex

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

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

Lua CLI Example

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

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

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

luatex document.tex

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

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

2.2.1.3 Option cacheDir

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:

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

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}

lualatex document.tex

ConT_eXt Example

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

\usemodule[t][markdown]

\starttext
\startmarkdown
Hello *world*!
\stopmarkdown
\stoptext

context --luatex document.tex

2.2.1.4 Option contentBlocksLanguageMap

L^aT_eX Example

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

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

{
  "tex": "LaTeX"
}

This is an example code listing in \LaTeX.

This is a *transcluded markdown document*.

\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}

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

ConT_eXt Example

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

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

{
  "tex": "ConTeXt"
}

This is an example code listing in \ConTeXt.

This is a *transcluded markdown document*.

\usemodule[t][markdown]
\setupmarkdown
  [
    contentBlocks = yes,
    contentBlocksLanguageMap = language-map.json,
  ]
\definetyping [ConTeXt]
\setuptyping  [ConTeXt] [option=TEX]

  local markdown = require("markdown")
  local convert = markdown.new({finalizeCache = true, frozenCacheFileName = "cache.tex"})
  local input = "Hello *world*!"
  tex.sprint(convert(input)) }
\endgroup
\bye

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

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

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

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:

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:

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

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:

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.

\usepackage[plain]{markdown}

\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.

\usepackage[noDefaults]{markdown}

\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}

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.

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

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:

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 inclde 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.

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}

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.

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

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:

\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}

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 kpathsea⁷ 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.
