Phabricator Formatting Syntax from https://secure.phabricator.com/book/phabricator/article/remarkup/

gistfile1.txt

= Overview =

Phabricator uses a lightweight markup language called "Remarkup", similar to
other lightweight markup languages like Markdown and Wiki markup.

This document describes how to format text using Remarkup.

= Quick Reference =

All the syntax is explained in more detail below, but this is a quick guide to
formatting text in Remarkup.

These are inline styles, and can be applied to most text:

  **bold** //italic// `monospaced` ##monospaced## ~~deleted~~ __underlined__
  !!highlighted!!
  D123 T123 rX123           # Link to Objects
  {D123} {T123}             # Link to Objects (Full Name)
  {F123}                    # Embed Images
  {M123}                    # Embed Pholio Mock
  @username                 # Mention a User
  #project                  # Mention a Project
  [[wiki page]]             # Link to Phriction
  [[wiki page | name]]      # Named link to Phriction
  http://xyz/               # Link to web
  [[http://xyz/ | name]]    # Named link to web
  [name](http://xyz/)       # Alternate Link

These are block styles, and must be separated from surrounding text by
empty lines:

  = Large Header =

  == Smaller Header ==

  ## This is a Header As Well

  Also a Large Header
  ===================

  Also a Smaller Header
  ---------------------

  > Quoted Text

  Use `- ` or `* ` for bulleted lists, and `# ` for numbered lists.
  Use ``` or indent two spaces for code.
  Use %%% for a literal block.
  Use | ... | ... for tables.

= Basic Styling =

Format **basic text styles** like this:

  **bold text**
  //italic text//
  `monospaced text`
  ##monospaced text##
  ~~deleted text~~
  __underlined text__
  !!highlighted text!!

Those produce **bold text**, //italic text//, `monospaced text`, ##monospaced
text##, ~~deleted text~~, __underlined text__, and !!highlighted text!!
respectively.

= Layout =

Make **headers** like this:

  = Large Header =

  == Smaller Header ==

  ===== Very Small Header =====

  Alternate Large Header
  ======================

  Alternate Smaller Header
  ------------------------

You can optionally omit the trailing `=` signs -- that is, these are the same:

  == Smaller Header ==

  == Smaller Header

This produces headers like the ones in this document. Make sure you have an
empty line before and after the header.

Lists
=====

Make **lists** by beginning each item with a `-` or a `*`:

  lang=text
  - milk
  - eggs
  - bread

  * duck
  * duck
  * goose

This produces a list like this:

  - milk
  - eggs
  - bread

(Note that you need to put a space after the `-` or `*`.)

You can make numbered lists with a `#` instead of `-` or `*`:

  # Articuno
  # Zapdos
  # Moltres

Numbered lists can also be started with `1.` or `1)`. If you use a number other
than `1`, the list will start at that number instead. For example, this:

```
  200) OK
  201) Created
  202) Accepted
```

...produces this:

  200) OK
  201) Created
  202) Accepted

You can also nest lists:

```- Body
  - Head
  - Arm
    - Elbow
    - Hand
      # Thumb
      # Index
      # Middle
      # Ring
      # Pinkie
  - Leg
    - Knee
    - Foot```

...which produces:

  - Body
  - Head
  - Arm
    - Elbow
    - Hand
      # Thumb
      # Index
      # Middle
      # Ring
      # Pinkie
  - Leg
    - Knee
    - Foot

If you prefer, you can indent lists using multiple characters to show indent
depth, like this:

```- Tree
-- Branch
--- Twig```

As expected, this produces:

- Tree
-- Branch
--- Twig

You can add checkboxes to items by prefacing them with `[ ]` or `[X]`, like
this:

```
  - [X] Preheat oven to 450 degrees.
  - [ ] Zest 35 lemons.
```

When rendered, this produces:

  - [X] Preheat oven to 450 degrees.
  - [ ] Zest 35 lemons.

Make **code blocks** by indenting two spaces:

  f(x, y);

You can also use three backticks to enclose the code block:

  ```f(x, y);
  g(f);```

You can specify a language for syntax highlighting with `lang=xxx`:

  lang=text
  lang=html
  <a href="#">...</a>

This will highlight the block using a highlighter for that language, if one is
available (in most cases, this means you need to configure Pygments):

  lang=html
  <a href="#">...</a>

You can also use a `COUNTEREXAMPLE` header to show that a block of code is
bad and shouldn't be copied:

  lang=text
  COUNTEREXAMPLE
  function f() {
    global $$variable_variable;
  }

This produces a block like this:

  COUNTEREXAMPLE
  function f() {
    global $$variable_variable;
  }

You can use `lines=N` to limit the vertical size of a chunk of code, and
`name=some_name.ext` to give it a name. For example, this:

  lang=text
  lang=html, name=example.html, lines=12, counterexample
  ...

...produces this:

  lang=html, name=example.html, lines=12, counterexample
  <p>Apple</p>
  <p>Apricot</p>
  <p>Avocado</p>
  <p>Banana</p>
  <p>Bilberry</p>
  <p>Blackberry</p>
  <p>Blackcurrant</p>
  <p>Blueberry</p>
  <p>Currant</p>
  <p>Cherry</p>
  <p>Cherimoya</p>
  <p>Clementine</p>
  <p>Date</p>
  <p>Damson</p>
  <p>Durian</p>
  <p>Eggplant</p>
  <p>Elderberry</p>
  <p>Feijoa</p>
  <p>Gooseberry</p>
  <p>Grape</p>
  <p>Grapefruit</p>
  <p>Guava</p>
  <p>Huckleberry</p>
  <p>Jackfruit</p>
  <p>Jambul</p>
  <p>Kiwi fruit</p>
  <p>Kumquat</p>
  <p>Legume</p>
  <p>Lemon</p>
  <p>Lime</p>
  <p>Lychee</p>
  <p>Mandarine</p>
  <p>Mango</p>
  <p>Mangostine</p>
  <p>Melon</p>


You can use the `NOTE:`, `WARNING:` or `IMPORTANT:` elements to call attention
to an important idea.

For example, write this:

```
NOTE: Best practices in proton pack operation include not crossing the streams.
```

...to produce this:

NOTE: Best practices in proton pack operation include not crossing the streams.

Using `WARNING:` or `IMPORTANT:` at the beginning of the line changes the
color of the callout:

WARNING: Crossing the streams can result in total protonic reversal!

IMPORTANT: Don't cross the streams!

In addition, you can use `(NOTE)`, `(WARNING)`, or `(IMPORTANT)` to get the
same effect but without `(NOTE)`, `(WARNING)`, or `(IMPORTANT)` appearing in
the rendered result. For example, this callout uses `(NOTE)`:

(NOTE) Dr. Egon Spengler is the best resource for additional proton pack
  questions.


Dividers
========

You can divide sections by putting three or more dashes on a line by
themselves. This creates a divider or horizontal rule similar to an `<hr />`
tag, like this one:

---

The dashes need to appear on their own line and be separated from other
content. For example, like this:

```
This section will be visually separated.

---

On an entirely different topic, ...
```


= Linking URIs =

URIs are automatically linked: http://phabricator.org/

If you have a URI with problematic characters in it, like
"`http://comma.org/,`", you can surround it with angle brackets:

  <http://comma.org/,>

This will force the parser to consume the whole URI: <http://comma.org/,>

You can also use create named links, where you choose the displayed text. These
work within Phabricator or on the internet at large:

  [[/herald/transcript/ | Herald Transcripts]]
  [[http://www.boring-legal-documents.com/ | exciting legal documents]]

Markdown-style links are also supported:

  [Toil](http://www.trouble.com)

= Linking to Objects =

You can link to Phabricator objects, such as Differential revisions, Diffusion
commits and Maniphest tasks, by mentioning the name of an object:

  D123          # Link to Differential revision D123
  rX123         # Link to SVN commit 123 from the "X" repository
  rXaf3192cd5   # Link to Git commit "af3192cd5..." from the "X" repository.
                # You must specify at least 7 characters of the hash.
  T123          # Link to Maniphest task T123

You can also link directly to a comment in Maniphest and Differential (these
can be found on the date stamp of any transaction/comment):

  T123#412       # Link to comment id #412 of task T123

See the Phabricator configuration setting `remarkup.ignored-object-names` to
modify this behavior.

= Embedding Objects

You can also generate full-name references to some objects by using braces:

  {D123}        # Link to Differential revision D123 with the full name
  {T123}        # Link to Maniphest task T123 with the full name

These references will also show when an object changes state (for instance, a
task or revision is closed). Some types of objects support rich embedding.

== Linking to Project Tags

Projects can be linked to with the use of a hashtag `#`. This works by default
using the name of the Project (lowercase, underscored). Additionally you
can set multiple additional hashtags by editing the Project details.

  #qa, #quality_assurance

== Embedding Mocks (Pholio)

You can embed a Pholio mock by using braces to refer to it:

  {M123}

By default the first four images from the mock set are displayed. This behavior
can be overridden with the **image** option. With the **image** option you can
provide one or more image IDs to display.

You can set the image (or images) to display like this:

  {M123, image=12345}
  {M123, image=12345 & 6789}

== Embedding Pastes

You can embed a Paste using braces:

  {P123}

You can adjust the embed height with the `lines` option:

  {P123, lines=15}

You can highlight specific lines with the `highlight` option:

  {P123, highlight=15}
  {P123, highlight="23-25, 31"}

== Embedding Images

You can embed an image or other file by using braces to refer to it:

  {F123}

In most interfaces, you can drag-and-drop an image from your computer into the
text area to upload and reference it.

Some browsers (e.g. Chrome) support uploading an image data just by pasting them
from clipboard into the text area.

You can set file display options like this:

  {F123, layout=left, float, size=full, alt="a duckling"}

Valid options for all files are:

  - **layout** left (default), center, right, inline, link (render a link
    instead of a thumbnail for images)
  - **name** with `layout=link` or for non-images, use this name for the link
    text
  - **alt** Provide alternate text for assistive technologies.

Image files support these options:

  - **float** If layout is set to left or right, the image will be floated so
    text wraps around it.
  - **size** thumb (default), full
  - **width** Scale image to a specific width.
  - **height** Scale image to a specific height.

Audio and video files support these options:

  - **media**: Specify the media type as `audio` or `video`. This allows you
    to disambiguate how file format which may contain either audio or video
    should be rendered.
  - **loop**: Loop this media.
  - **autoplay**: Automatically begin playing this media.

== Embedding Countdowns

You can embed a countdown by using braces:

  {C123}

= Quoting Text =

To quote text, preface it with an `>`:

  > This is quoted text.

This appears like this:

> This is quoted text.

= Embedding Media =

If you set a configuration flag, you can embed media directly in text:

  - **remarkup.enable-embedded-youtube**: allows you to paste in YouTube videos
    and have them render inline.

This option is disabled by default because it has security and/or
silliness implications. Carefully read the description before enabling it.

= Image Macros =

You can upload image macros (More Stuff -> Macro) which will replace text
strings with the image you specify. For instance, you could upload an image of a
dancing banana to create a macro named "peanutbutterjellytime", and then any
time you type that string on a separate line it will be replaced with the image
of a dancing banana.

= Memes =

You can also use image macros in the context of memes. For example, if you
have an image macro named `grumpy`, you can create a meme by doing the
following:

  {meme, src = grumpy, above = toptextgoeshere, below = bottomtextgoeshere}

By default, the font used to create the text for the meme is `tuffy.ttf`. For
the more authentic feel of `impact.ttf`, you simply have to place the Impact
TrueType font in the Phabricator subfolder `/resources/font/`. If Remarkup
detects the presence of `impact.ttf`, it will automatically use it.

= Mentioning Users =

In Differential and Maniphest, you can mention another user by writing:

  @username

When you submit your comment, this will add them as a CC on the revision or task
if they aren't already CC'd.

Icons
=====

You can add icons to comments using the `{icon ...}` syntax. For example:

  {icon camera}

This renders: {icon camera}

You can select a color for icons:

  {icon camera color=blue}

This renders: {icon camera color=blue}

For a list of available icons and colors, check the UIExamples application.
(The icons are sourced from
[[ https://fontawesome.com/v4.7.0/icons/ | FontAwesome ]], so you can also
browse the collection there.)

You can add `spin` to make the icon spin:

  {icon cog spin}

This renders: {icon cog spin}


= Phriction Documents =

You can link to Phriction documents with a name or path:

  Make sure you sign and date your [[legal/Letter of Marque and Reprisal]]!

By default, the link will render with the document title as the link name.
With a pipe (`|`), you can retitle the link. Use this to mislead your
opponents:

  Check out these [[legal/boring_documents/ | exciting legal documents]]!

Links to pages which do not exist are shown in red. Links to pages which exist
but which the viewer does not have permission to see are shown with a lock
icon, and the link will not disclose the page title.

If you begin a link path with `./` or `../`, the remainder of the path will be
evaluated relative to the current wiki page. For example, if you are writing
content for the document `fruit/` a link to `[[./guava]]` is the same as a link
to `[[fruit/guava]]` from elsewhere.

Relative links may use `../` to transverse up the document tree. From the
`produce/vegetables/` page, you can use `[[../fruit/guava]]` to link to the
`produce/fruit/guava` page.

Relative links do not work when used outside of wiki pages. For example,
you can't use a relative link in a comment on a task, because there is no
reasonable place for the link to start resolving from.

When documents are moved, relative links are not automatically updated: they
are preserved as currently written. After moving a document, you may need to
review and adjust any relative links it contains.


= Literal Blocks =

To place text in a literal block use `%%%`:

  %%%Text that won't be processed by remarkup
  [[http://www.example.com | example]]
  %%%

Remarkup will not process the text inside of literal blocks (other than to
escape HTML and preserve line breaks).

= Tables =

Remarkup supports simple table syntax. For example, this:

```
| Fruit  | Color  | Price   | Peel?
| -----  | -----  | -----   | -----
| Apple  | red    | `$0.93` | no
| Banana | yellow | `$0.19` | **YES**
```

...produces this:

| Fruit  | Color  | Price   | Peel?
| -----  | -----  | -----   | -----
| Apple  | red    | `$0.93` | no
| Banana | yellow | `$0.19` | **YES**

Remarkup also supports a simplified HTML table syntax. For example, this:

```
<table>
  <tr>
    <th>Fruit</th>
    <th>Color</th>
    <th>Price</th>
    <th>Peel?</th>
  </tr>
  <tr>
    <td>Apple</td>
    <td>red</td>
    <td>`$0.93`</td>
    <td>no</td>
  </tr>
  <tr>
    <td>Banana</td>
    <td>yellow</td>
    <td>`$0.19`</td>
    <td>**YES**</td>
  </tr>
</table>
```

...produces this:

<table>
  <tr>
    <th>Fruit</th>
    <th>Color</th>
    <th>Price</th>
    <th>Peel?</th>
  </tr>
  <tr>
    <td>Apple</td>
    <td>red</td>
    <td>`$0.93`</td>
    <td>no</td>
  </tr>
  <tr>
    <td>Banana</td>
    <td>yellow</td>
    <td>`$0.19`</td>
    <td>**YES**</td>
  </tr>
</table>

Some general notes about this syntax:

  - your tags must all be properly balanced;
  - your tags must NOT include attributes (`<td>` is OK, `<td style="...">` is
    not);
  - you can use other Remarkup rules (like **bold**, //italics//, etc.) inside
    table cells.

Navigation Sequences
====================

You can use `{nav ...}` to render a stylized navigation sequence when helping
someone to locate something. This can be useful when writing documentation.
For example, you could give someone directions to purchase lemons:

{nav icon=home, name=Home >
Grocery Store >
Produce Section >
icon=lemon-o, name=Lemons}

To render this example, use this markup:

```
{nav icon=home, name=Home >
Grocery Store >
Produce Section >
icon=lemon-o, name=Lemons}
```

In general:

  - Separate sections with `>`.
  - Each section can just have a name to add an element to the navigation
    sequence, or a list of key-value pairs.
  - Supported keys are `icon`, `name`, `type` and `href`.
  - The `type` option can be set to `instructions` to indicate that an element
    is asking the user to make a choice or follow specific instructions.

Keystrokes
==========

You can use `{key ...}` to render a stylized keystroke. For example, this:

```
Press {key M} to view the starmap.
```

...renders this:

> Press {key M} to view the starmap.

You can also render sequences with modifier keys. This:

```
Use {key command option shift 3} to take a screenshot.
Press {key down down-right right LP} to activate the hadoken technique.
```

...renders this:

> Use {key command option shift 3} to take a screenshot.
> Press {key down down-right right LP} to activate the hadoken technique.


Anchors
========

You can use `{anchor #xyz}` to create a document anchor and later link to
it directly with `#xyz` in the URI.

Headers also automatically create named anchors.

If you navigate to `#xyz` in your browser location bar, the page will scroll
to the first anchor with "xyz" as a prefix of the anchor name.


= Fullscreen Mode =

Remarkup editors provide a fullscreen composition mode. This can make it easier
to edit large blocks of text, or improve focus by removing distractions. You can
exit **Fullscreen** mode by clicking the button again or by pressing escape.
