You can add CSS to change the styles. See the Custom Formatting section
for some examples.
Formatted text may **cross
lines** and be as small as **a** single character. It can _also
be indented and
split across lines_ simultaneously.
Markdeep intelligently does not apply bold or italic formatting to
math expressions such as x = 3 * y - 2 * z or WORDS_WITH_INTERNAL_UNDERSCORES.
It also protects HTML `
`
Captionless images work as well. Source `` becomes:
Images are centered if they appear in their own paragraph block and inlined otherwise. Grids of
images are recognized and laid out as grids using HTML tables:
  
   Video file extensions are automatically detected and will embed a small video player:  URLs for Youtube and Vimeo videos will also automatically embed a video player:  ![Figure [fig:boy]: The Boy with a Camera For a Face](https://vimeo.com/channels/staffpicks/151493973) URLs for images may be surrounded in optional `"` quotation `"` marks. If your URL contains parentheses, then it _must_ be surrounded in quotation marks to make it unambigious. Recall that URLs are not permitted to contain spaces (by their specification), so to embed a local image whose filename has a space, either rename the file or replace the spaces with `%20` in the URL version of the name. Symbol Substitutions ------------------------------------------------------------------------------ Markdeep converts `<->`, `<==>`, `->`, `-->`, `<-`, `<--`, `==>`, and `<==` to arrows if they aren't in a code block or latex expression and are surrounded by whitespace. Examples: - if this ==> then that - here <== there - this <==> that - A <- B - X -> Y - back <-> forth - long --> way - back <-- there Two or three minus signs are converted to an em dash--like that. An "x" between numbers, such as 1920x1080 or 3 x 4, will be converted to the times symbol. Negative numbers, such as -5 and minus signs between numbers such as 2 - 1, will have a minus sign instead of a hyphen. Degrees are reformatted to the degree symbol: - Cold, 37-degree F water. - A 45-degree angle. - A right angle's measure is 90 degrees. It doesn't reformat the word "degree" when not following digits: - Don't give me the third degree! - I have two degrees from MIT. "Smart quotes" are applied for double-quote marks based on position relative to whitespace: "a" b c a "b" c a b "c" a "b!" c a "b," c a "b". C a, "b" c a---"b"---c a ("b") c "error" ==> "correction" Inch or minute markers such as 3' 9" are not converted. Quotation marks in HTML attributes and in code blocks, e.g., `var x = "hello world"`, are not converted. Admonitions ----------------------------------------------------------------------------- Admonitions are small break-out boxes with notes, tips, warnings, etc. for the reader. They begin with a title line of a pattern of three exclaimation marks, an optional CSS class, and an optional title. All following lines that are indented at least three spaces are included in the body, which may include multiple paragraphs. The default stylesheet provides classes for "note" (default), "tip", "warning", and "error". These are case insensitive and ignore any colon after the CSS class. Here are some examples: ````````````````````````````````````````````````````````````` none !!! I'm a note. Don't mind me, I'm just sitting here. !!! note Another note. !!! Tip Close the door on the way out. !!! WARNING I'm a warning, perhaps. *Something might happen!* !!! ERROR: Seriously Watch out, something **bad** could happen. This is still more error text. ````````````````````````````````````````````````````````````` !!! I'm a note. Don't mind me, I'm just sitting here. !!! note Another note. !!! Tip Close the door on the way out. !!! WARNING I'm a warning, perhaps. *Something might happen!* !!! ERROR: Seriously Watch out, something **bad** could happen. This is still more error text. Fenced Code Blocks ------------------------------------------------------------------------------ Set off large blocks of code using equal-length strings of tilde `~` or back-tick
` characters. Each produces a different CSS
class so that they can be styled differently.
By default, tilde blocks have lines before and after them and are
inset for use as code listings instead of large inline code
blocks. Both styles receive syntax coloring and automatic programming
language detection.
You can override automatic programming language detection by putting
the name of the language immediately following the first fence. You can
specify a custom CSS class for a code block by placing its name after the
language name.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ C void insertion_sort(int data[], int length) { for (int i = 0; i < length; ++i) { ... } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Alternative back-tick markup: ```````````````````````````````````` def insertionSort(data): for i in range(0, len(data)): j = i; while (j > 0) and (data[j] < data[j - 1]): temp = data[j] data[j] = data[j - 1] data[j] = temp --j ```````````````````````````````````` ### HTML and LaTeX Blocks You can even have HTML in a code block: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Show this HTML as source,~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cvoid insertion_sort(int data[], int length) { for (int i = 0; i < length; ++i) { ... } }~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
not code.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
LaTeX and other languages that use dollar signs work fine inside code
fences:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$ \int_0^1 x^2 dx $
$$$a = $$$e
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...and of course, Markdeep inside Markdeep:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Do not
- Format
- this as a **list**!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
### Code Blocks with Captions
Code listings may have captions:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Python
def insertionSort(data):
for i in range(0, len(data)):
j = i;
while (j > 0) and (data[j] < data[j - 1]):
temp = data[j]
data[j] = data[j - 1]
data[j] = temp
--j
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[Listing [sort]: An insertion sort]
If you don't have a lot of exposition to share, then code blocks can be back to back:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
printf("Hello\n");
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
printf("World\n");
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
### Multi-code Blocks and Custom CSS
You can interlace different languages or CSS classes within a single code block, but each is required
to specify the language in this case. This is convenient for highighting lines or showing the
trace of an interactive session.
An example of a fenced code block with a CSS class:
And its result: ~~~~~~~~~~~~~~ Python input >>> x = [1, 2, 3, 4] >>> [y * 2 for y in x] ~~~~~~~~~~~~~~ none output [2, 4, 6, 8] ~~~~~~~~~~~~~~ Python input >>> x + [5] ~~~~~~~~~~~~~~ none output [1, 2, 3, 4, 5] ~~~~~~~~~~~~~~ [This listing combines multiple code blocks to show the input and output of an interactive section.] ### Less-than Signs in Code ### #### Summary #### If you have trouble with less-than signs right next to capitalized letters in code blocks, do _one_ of the following: - Put spaces after angle brackets: `std::vector< Capitalized >` - Use HTML entity escapes: `std::vector<Capitalized>` - Wrap code examples in `<script type="preformatted">...</script>` - Wrap your whole document in `<script type="preformatted">...</script>` You don't need to do this for legal HTML or XML in code blocks. #### Details #### Less-than and greater-than signs are allowed in code blocks (as well as anywhere else in Markdeep), and will be handled correctly if they are followed by a whitespace character. Likewise, legal HTML and XML are correctly processed as code when in code blocks. However, because browsers interpret "`<`" _immediately followed by_ a character as an HTML tag, less-than signs without a following space must be formatted more carefully in shell scripts and languages such as C++ and Java. If the character following the less-than sign is lower-case, for example in: "`std::vector<int>`", then no consideration is needed. If the character following less-than is a capital letter, then the browser will automatically make it lower case. If the following character is a slash, then the browser will interpret it as a stray tag and automatically remove it. If you care most about being able to read your document in a browser when the markdeep.js script is not available (due to no local copy and no Internet connection), then either use surrounding whitespace or use HTML entity codes to avoid incorrect processing of less-than signs. **Reformatted Examples:** ~~~~~~~~~~~~~~~~~~~~ #include <foo.h> ls < /dev/null ls</dev/null std::vector< Capitalized > array; std::vector<Capitalized> array; ~~~~~~~~~~~~~~~~~~~~ If care more about not having to reformat your code examples, then just include them in preformatted `<script>` blocks: **Script Block Examples:** You can also include your entire document in a preformatted script block to avoid the need for marking up each code (and inline code) example.

Embedded Math
========================
Markdeep automatically includes [MathJax](http://mathjax.org) if your
document contains equations and you have an Internet connection. That means
you get the **full power of LaTeX, TeX, MathML, and AsciiMath notation**.
Just put math inside single or double dollar signs.
$$ \Lo(X, \wo) = \Le(X, \wo) + \int_\Omega \Li(X, \wi) ~ f_X(\wi, \wo) ~ | \n \cdot \wi | ~ d\wi $$
You can also use LaTeX equation syntax directly to obtain numbered
equations:
\begin{equation}
e^{i \pi} + 1 = 0
\end{equation}
\begin{equation}
\mathbf{A}^{-1}\vec{b} = \vec{x}
\end{equation}
If you don't have equations in your document, then Markdeep won't
connect to the MathJax server. Either way, it runs MathJax after
processing the rest of the document, so there is no delay.
Markdeep is smart enough to distinguish non-math use of dollar signs,
such as $2.00 and $4.00, US$5, and 3$. Inline
math requires consistent spaces (or punctuation) either outside or inside
of the LaTeX dollar signs to distinguish them from
regular text usage. Thus, the following all work:
- $x^2$
- $ x^2 $
- ($x^2$)
- ($ x^2 $)
- Variable $x^2$,
- Variable $ x^2 $
- Two $x$ vars $y$ on the same line
- Different spacing styles: $\theta_{x}$ vs. $ \theta_{y} $
Unless you've changed out the default MathJax processor, you can define
your own LaTeX macros by executing `\newcommand` within dollar signs,
just as you would in LaTeX. Markdeep provides a handful of commands
defined this way by default because they're things that I frequently
need:
Code | Symbol
-------------------|------------
`\O(n)` | $\O(n)$
`\mathbf{M}^\T` | $\mathbf{M}^\T$
`45\degrees` | $45\degrees$
`x \in \Real` | $x \in \Real$
`x \in \Integer` | $x \in \Integer$
`x \in \Boolean` | $x \in \Boolean$
`x \in \Complex` | $x \in \Complex$
`\n` | $\n$
`\w` | $\w$
`\wo` | $\wo$
`\wi` | $\wi$
`\wh` | $\wh$
`\Li` | $\Li$
`\Lo` | $\Lo$
`\Lr` | $\Lr$
`\Le` | $\Le$
`10\un{m/s^2}` | $10\un{m/s^2}$
# ATX Headers
In addition to the underlined headers, you can also use ATX-style
headers, with multiple # signs:
## H2
### H3
#### H4
##### H5
###### H6
Although: do you really need six levels of subsection nesting?!
You can also create unnumbered sections that will not appear in the
table of contents using parentheses around the pound signs:
(##) Unnumbered H2
Multiple Columns
========================================================================
You can use the CSS
[columns](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Columns/Using_multi-column_layouts)
style to make an HTML multicolumn block. Then, just use regular Markdeep within it and the
browser will automatically apply your multicolumn layout.
Browsers are even smart enough to break the columns correctly when
printing to PDF or to a printer. However, for a long document,
multiple columns don't work well when displayed on screen. That's
because there are no discrete "pages" on screen to break columns. So,
the browser will make each column as long as the entire document,
which is probably not what you want.
So, multi-column only works well if you know that you have very short
sections (as in this example), or if you were planning on printing to
separate pages when done.
Custom Formatting
=========================================================================
Manual
-------------------------------------------------------------------------
Markdeep uses CSS for styling. That means you can embed a style sheet
to override anything thatn you don't like about the built-in styling.
For example, if you don't want section numbering, just use:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Markdeep uses Markdown's syntax, even where I disagree with the
choices. But you aren't stuck with that. Do you wish that Markdown
had specified single-asterisk for `*bold*`? You can have
that:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<style>em.asterisk { font-style: normal; font-weight: bold; }</style>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Each of the list bullets (`+`, `-`, `*`) has its own CSS class. You
can use this, for example, to make `+` entries bold and `-` ones
use a circle:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<style>
li.plus { font-weight: bold; }
li.minus { list-style-type: circle;}
</style>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Style Sheets
------------------------------------------------------------------------
### Latex Article
To match the default Latex article formatting, insert the following anywhere in your document:
<link rel="stylesheet" href="https://casual-effects.com/markdeep/latest/latex.css?">
### Dark
For an aggressively-stylized document with a black background, insert the following anywhere in
your document:
<link rel="stylesheet" href="https://casual-effects.com/markdeep/latest/dark.css?">
### API Documentation
To use the API documentation template, insert the following anywhere in
your document:
<link rel="stylesheet" href="https://casual-effects.com/markdeep/latest/apidoc.css?">
### Presentation Slides
To create presentation slides as a PDF, insert the following into
your document, using first-level headers for sections and second-level
headers for slides:
<link rel="stylesheet" href="https://casual-effects.com/markdeep/latest/slides.css?">
Then, print the document to PDF.
Paragraph Numbering
--------------------------------------------------
Academic article or book proofs often have line numbers so that reviewers and editors can refer
to specific passages. This doesn't make sense for a document in a browser because line breaks
change based on the reader's screen size.
You can add _paragraph_ numbers to your Markdeep document by including the following HTML at
the bottom of your document. You can remove the `
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Localization
===================================================
There are two ways to localize the keywords such as Table, Diagram,
Monday, etc., from English to your favorite language.
The first is to
put a meta tag with a
[`lang`](http://www.iana.org/assignments/language-subtag-registry/language-subtag-registry)
attribute in the document, such as <`meta lang="ru"
charset="utf-8"`>. If your favorite language isn't supported by
Markdeep, just e-mail me a Javascript snippet with the appropriate
translations and I'll add it (see the source code for examples).
The second method is to manually set the `markdeepOptions.lang` field
before you include the script in your document.
Unicode (in UTF-8 encoding)
===================================================
To support Unicode input, you must add <`meta charset="utf-8"`> to
the *top* of your document (in the first 512 bytes).

Gravizo Support
===================================================
Markdeep diagrams have no dependency on third parties or the network
(you can store the `markdeep.min.js` file locally on your machine!)
and look the same in your document as on screen in the final document.
If you need the full power of DOT/GraphViz automated layout graphs and
can accept a network and third party dependency, you can embed
[Gravizo](http://g.gravizo.com/) within a Markdeep document using either
direct Markdeep image syntax or an embedded HTML `img` tag:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
` and `` tags
that appear in the document, you cannot nest a code tag inside of another code tag, and
likewise for pre tags. Fortunately, it is pretty hard to imagine a case where you would want
nested code tags.
