# Fancybox Test

## 1 Links in Hugo using Org-Mode

Org-mod does not know about Hugo, and that is reflected in how org-mode handles links. Here we discuss how to handle links in org-mode. It's a little bit of work, but not that much.

Note that this file is called hugo_ormode.org and contains a lot of formatting to show the source code for doing an org file on this web page. For a more normal example org file, see sample_orgmode.org in the /asl content directory. Note: Hugo copies *.org files to the actual web site, so you can always download the source for a page by removing the trailing \ and adding .org to the URL you are viewing.

## 2 Blah blah

Code blocks, examples, prose, etc can be done a number of ways, two ways are shown below, see the source code of this document to see how these are done.

#+BEGIN_SRC text
Here is the rendering of an =in-line code block=.  Is was done by
enclosing the code block in =, as shown below where we repeat these
last two sentences.
#+END_SRC

Here is the rendering of an =in-line code block=.  Is was done by
enclosing the code block in =, as shown below where we repeat these
last two sentences.


Note that the code block rendering will render carriage return, line feeds if they exist.

To render a matlab file (or latex, or html, etc) just use the backticks, and put the language right after the first set of three backticks. I would generally put language of "text" for notes, or if you do not want automatic colorization, etc. I can't figure out how to render a code block inside a code block, so look at the source of this file (/strow/hugo_orgmode.md) to see how this works.

% A matlab code snippet
for i=1:n
a(i) = fact(i);
end


If you want to make this look like the Hugo markdown, there is a slightly more complicated way to do the above, shown below and then rendered.

#+BEGIN_EXPORT HTML
<pre><code class="language-matlab">% A matlab code snippet
for i=1:n
a(i) = fact(i);
end
</code></pre>
#+END_EXPORT

% A matlab code snippet
for i=1:n
a(i) = fact(i);
end


## 3 Figures

This document tests fancybox. Sure seems easy.

## 4 Math

To include a mathematical formula in-line using org-mode, just use normal latex syntax. Here is some in-line math $a = α × β.$ For latex equations or displaymath just type them in the file as usual:

$$\frac{n!}{k!(n-k)!} = \binom{n}{k}$$


which gives,

$$\frac{n!}{k!(n-k)!} = \binom{n}{k}.$$

## 5 Lists

Lists work out of the box (enumerated or itemize)

1. Just write a Markdown document, and sprinkle your LaTeX code
snippets in between.
1. Save the document with an .md suffix.
1. Run the Pandoc conversion:

There is a css formating bug somewhere that puts in the extra space after a nested list.

## 6 Tables

External stuff here????

Hugo is limited to simple tables, org-mode provides much more flexibility. Here is the Hugo (default markdown) table syntax, followed by it's html rendering. The code block is fancier than it's rendering…

Here is a table using org-mode, followed by the code. Unfortunately, there is a bug in org-mode that doesn't put a carriage-return, line-feed after a left-justified table, so avoid those for now.

Table 1: The table caption
Name Age
Bob 27
Alice 23

The code. If you don't center the table, the rendering goes bad.

#+ATTR_html: :align center :width 200
#+CAPTION: the caption
Name   |  Age
-------|------
Bob    |  27
Alice  |  23


You can get org-mode to produce your table of contents quite easily, you just have to put the following, #+TOC: headlines 2, on the line right after the #END_EXPORT command in your Hugo configuration sections at the top of the file. The "2" refers to how deep you want the table of contents sectioning.

## 8 Fenced Matlab Code Block

Here is an example of a Matlab fenced code block. Note, you can do ascii tables inside code block if you like. Looks at the source for this file to see how to do this.

% A matlab code snippet
% NAME
%   rad2bt - translate radiance to brightness temperature
%
% SYNOPSIS
%
% INPUTS
%   fr  - n-vector of wavenumbers, cm-1
%   rad - n x k array of radiances, mW/m2 per strad
%
% OUTPUT
%   bt  - n x k array of brightness temps, K
