UI escape sequences

Many UI elements that display text on the screen support special escape sequences starting with the | pipe character.
== Escape Sequences ==
=== Coloring ===
 |cAARRGGBBtext|r
* Each pair of digits represents a color value (plus the alpha value, however the alpha value is currently ignored and should always be FF) as a hexadecimal number. The |r escape sequence pops nested color sequences in-order.
/run print("this is \124cFFFF0000red and \124cFF00FF00this is green\124r back to red\124r back to white")
 > this is red and this is green back to red back to white
==== Global Colors ====
 |cncolorname:text|r
* Renders a text string with a named global color.
/run print("Normal Text \124cnPURE_GREEN_COLOR:Green Text \124cnPURE_RED_COLOR:Red Text\124r Green Text\124r Normal Text")
 > Normal Text Green Text Red Text Green Text Normal Text
=== Textures ===
 |Tpath:height[:width[:offsetX:offsetY[:textureWidth:textureHeight:leftTexel:rightTexel:topTexel:bottomTexel[:rVertexColor:gVertexColor:bVertexColor]]]]|t
: Will insert a texture into a font string. Parameter width is optional (see below). The offsets are optional and will shift the texture from where it would normally be placed. TextHeight is based on size of the font used - this is used to automatically scale icons based on the size of the text.
:*height == 0; width omitted: Width = Height = TextHeight (always square!)
:*height > 0;  width omitted: Width = Height = height (always square!)
:*height == 0; width == 0   : Width = Height = TextHeight (always square!)
:*height > 0;  width == 0   : Width = TextHeight; Height = height (height is height!!!)
:*height == 0; width > 0    : Width = width * TextHeight; Height = TextHeight (width is an aspect ratio and defines width!!!)
:*height > 0;  width > 0    : Width = width; Height = height
:*offsetX offsetY: Offset for the rendered image, in pixels
:*textureWidth textureHeight: Size of the source image, in pixels
:*leftTexel rightTexel topTexel bottomTexel: (x1 x2 y1 y2) Coordinates that identify the left/right/top/bottom edges, in pixels (see () but non-normalized)
:*rVertexColor gVertexColor bVertexColor: RGB color values in the range 0-255 that are used to tint the texture
:Notes:
:* When you need to display a square icon in the string (spell/item icon), use only |Tpath:0|t
:* When you need to display a rectangular image in the string (Blizzard logo), use aspect ratio version: |Tpath:0:aspectRatio|t
=== Texture atlas ===
Atlases allow for easily getting part of a texture without having to use tex coords.
 |A:atlas:height:width[:offsetX:offsetY[:rVertexColor:gVertexColor:bVertexColor]]|a
=== Examples ===
* Both slash / or escaped backslashes \\ are valid file separators.
* Parameters that are zeros can be omitted in between :characters.

=== Protected strings ===
Also known as Kstrings - they prevent strings from being parsed. For example addons/scripts only see the string |Kq1|k instead of the actual displayed name.
* q for the confidentiality of Battle.net account names in ().
* r for the name and comment in group finder listings in () and ().
* u prevents using the message history as a persistent data storage in () and ().
* v for the message in .
=== Grammar ===
====Korean====
text|1A;B; is for Korean postpositions. For example object particles - Eul 을 is used following a consonant, Reul 를 is used following a vowel.
 print("라면|1을;를;") -- 라면을 ramyeoneul
 print("나무|1을;를;") -- 나무를 namureul
====French====
|2 text is for French prepositions - de before a consonant and d' before a vowel. Having zero, one or multiple trailing spaces after |2 does not matter for the end result.
print("|2 fraise") -- de fraise
print("|2 avion") -- d'avion
====Russian====
|3-id(text) is for the Russian declension of nouns (including proper names) which take different forms based on their usage in a sentence. See also ().
print("|3-1(Кролик)") -- Кролика
print("|3-2(Кролик)") -- Кролику
print("|3-3(Кролик)") -- Кролика
print("|3-4(Кролик)") -- Кроликом
print("|3-5(Кролик)") -- Кролике
====Plural====
number |4singular:plural; or number |4singular:plural1:plural2; for ruRU. This assigns the singular or plural form depending on the number.
print("1 |4car:cars;") -- 1 car
print("2 |4car:cars;") -- 2 cars
print("3 blue |4car:cars;") -- 3 blue cars
number |7singular:plural; behaves the same as |4 but appears to only work while on certain non-english locales.
print("1 |7Million:Millionen;") -- 1 Million
print("2 |7Million:Millionen;") -- 2 Millionen
====A or an====
|5 text is for indefinite articles, a is used before words starting with a consonant sound, an is used before words starting with a vowel sound.
print("|5 banana") -- a banana
print("|5 apple") -- an apple
====Lowercase====
|6 TEXT appears to convert only the next word to lowercase.
print("|6 HELLO WORLD") -- hello WORLD
=== Word Wrapping ===
 |Wtext|w
Hints that word wrapping of text should be avoided where possible. If the text would require wrapping the client will prefer to wrap before the start of the sequence instead of breaking it up. If the text is still too large, the hint may be ignored and the text broken up regardless.
=== Other ===
: |n: Newline, if the widget supports it. Similar behavior as \n and \r
: ||: Escapes the "|" character.
: Any invalid escape sequences will be displayed as-is or is otherwise undefined behavior.
