Documents written in this extended markup language can be converted into HTML or LaTeX: Render as HTML:: Use `asciidoctor-latex -b html foo.adoc` to produce `foo.html`. Render as LaTeX:: Use `sasciidoctor-latex foo.adoc` to produce `foo.tex`, then use `xelatex foo.tex` to create `foo.pdf`. Below, we describe the main features of {adl}. However, since this document will not render fully in GitHub, you are encouraged to compile it yourself using `asciidoctor-latex -b html README.adoc` or to consult the http://vschool.s3.amazonaws.com/asciidoctor-latex/README.html[README at S3]. There is also an online version hosted at http://www.shoobox.io/share/230[shoobox.io], a site for editing and distributing Asciidoc and Asciidoc-LaTeX documents. Asciidoctor-LaTeX is developed by James Carlson, Jakub Jirutka, and Dan Allen. Display of mathematical text relies on http://docs.mathjax.org/en/latest/start.html[MathJax]. == Features {adl} renders inline and displayed mathematical, and it supports a construct akin to LaTeX environments for theorems, equations, etc. These and other features are described briefly below and more fully in <>. === Inline and displayed formulas ifdef::env_standard[] .Example Imagine that `foo.adoc` contains the text below. The inline and displayed formulas will be correctly rendered as html or tex. ---- The formula $a^2 + b^2 = c^2$ relates the sides and hypotenuse of a right triangle. The formula \[ \int_0^1 x^n dx = \frac{1}{n+1} \] is something we all learn in Calculus ---- endif::[] ifndef::env_standard[] .Example Imagine that `foo.adoc` contains the text below.

If you click on the title, the body is displayed. Click on the title again to hide the body. The title of a click block is displayed in blue. ifdef::env_standard[] .Example -- -- ---- [env.question] -- What is the speed of light? -- [click.answer] -- 300,000 km/sec -- ---- endif::[] ifndef::env_standard[] .Example -- -- ---- [env.question] -- What is the speed of light? -- [click.answer] -- 300,000 km/sec -- ---- .Rendered Text -- -- [env.question] -- What is the speed of light? -- [click.answer] -- 300,000 km/sec -- endif::[] == Installation === From Rubygems Run `gem install asciidoc-latex` to install from https://rubygems.org/gems/asciidoctor-latex[RubyGems.org]. See the https://github.com/asciidoctor/asciidoctor-latex/blob/master/CHANGELOG.adoc[change log] for a list of updates. === From GitHub If you would like to install a development version from the repository, use: $ git clone https://github.com/asciidoctor/asciidoctor-latex.git $ cd asciidoctor-latex $ gem build asciidoctor-latex.gemspec $ gem install *.gem == Contributing If you wish to contribute to the https://github.com/asciidoctor/asciidoctor-latex[asciidoctor-latex project], you should set up your environments to use Jakub Jirutka's https://github.com/asciidoctor/asciidoctor-doctest[asciidoctor-doctest]. At the moment you will need to use the https://github.com/jxxcarlson/asciidoctor-doctest[version which handles dialects] using ``` gem 'asciidoctor-doctest', github: 'jxxcarlson/asciidoctor-doctest', ref: 'latex' ``` in your Gemfile. Run all tests with `rake doctest`, or run individual tests with `rake doctest:html` or `rake doctest:tex`. At the moment the tests are for the latex dialect. == Dialects `Asciidoctor-LaTeX` processes three dialects of the core Asciidoc language: - `asciidoc` (the core language) - `manuscript` - `latex` `Asciidoc-latex` is the default dialect. Dialects can be set with the `:dialect` on the command line as in this example: ``` asciidoctor-latex -a dialect=manuscript foo.adoc ``` To set the dialect with the Ruby API, use for example : ``` Asciidoctor.convert str, { 'dialect' => 'latex' } ``` == Macros Macros can be included in the body of an Asciidoc-LaTeX file using the `texmacro` environment, as in the example below. ---- [env.texmacro] -- \def\AA{\mathbb{A}} \def\BB{\mathbb{B}} \newcommand{\set}[1]{ \{\,#1\, \} } \newcommand{\sett}[2]{ \{\,#1\, \mid\, #2\, \} } -- ---- To include a LaTeX macro file MACRO_FILE, insert the code `include_latex_macros::MACRO_FILE[]`. Here MACRO_FILE can be a file name or a an absolute or relative path. Included macros work for both the html and tex backends. NOTE: Automatic inclusion of the file `macros.tex` has been discontinued. == Switches .Tex header To generate a tex file with a minimal header, do: $ asciidoctor-latex -a header=no foo.adoc .Print style An alternate css file, `data/print.css` is provided for printing. It features wider margins and a smaller type size. Copy it to the root of your document folder and use the command `asciidoctor-latex -a stylesheet=print.css` or more generally `asciidoctor-latex -a stylesheet=path_to/print.css`. {adlp}'s default form at is `:latexmath`. To use `:stem`, put the text `:stem:` in your file. To turn the switch on and set it to `latexmath`, say instead of `stem:latexmth`. == Document format Asciidoctor supports two closely-related math formats, [blue]#Asciidoc-LaTeX# and [blue]#AsciiMath#. In Asciidoc-LaTeX, one can write `\$ a^2 + b^2 = c^2 \$` and ---- \[ e^{2\pi \sqrt{-1}} = 1, \] ---- for in-line and display mathematial text, respectively. You will need to express dollar-denominated currency using escaped dollar signs, as in the sentence, "He paid \$100 for that theorem." In AsciiMath, one writes `+++stem:[ a^2 + b^2 = c^2 ]+++` and ---- [stem] ++++ e^{2\pi \sqrt{-1}} = 1. ++++ ---- ifdef::env_standard[] == Asciidoc-LaTeX environments Asciidoc-LaTeX supports an `env` construct that maps to LaTeX environments.

For numbered equations, use `[env.equation]` like this ---- [env.equation] -- a^{p-1} \equiv 1\ \text{mod}\ p -- ---- An equation number will be displayed only when a label for cross-referencing is provided, e.g., ---- [env.equation#little-fermat] -- a^{p-1} \equiv 1\ \text{mod}\ p -- ---- For sets of equations, use `[env,equationalign]`: ---- [env.equationalign] -- A & = 4\pi r^2 \\ V & = \frac{4}{3} \pi r^3 -- ---- endif::[] ifndef::env_standard[] == Asciidoc-LaTeX environments Asciidoc-LaTeX supports an `env` construct that maps to LaTeX environments.
