Creole

A light Creole engine has been integrated into PlantUML to have a standardized way of defining text style.

All diagrams are now supporting this syntax.

Note that ascending compatibility with HTML syntax is preserved.

Emphasized text

@startuml
Alice -> Bob : hello --there--
... Some ~~long delay~~ ...
Bob -> Alice : ok
note left
  This is **bold**
  This is //italics//
  This is ""monospaced""
  This is --stroked--
  This is __underlined__
  This is ~~waved~~
end note
@enduml

List

@startuml
object demo {
  * Bullet list
  * Second item
}
note left
  * Bullet list
  * Second item
  ** Sub item
end note

legend
  # Numbered list
  # Second item
  ## Sub item
  ## Another sub item
  # Third item
end legend
@enduml

Escape character

You can use the tilde ~ to escape special creole characters.

@startuml
object demo {
  This is not ~___underscored__.
  This is not ~""monospaced"".
}
@enduml

Horizontal lines

@startuml
database DB1 as "
You can have horizontal line
----
Or double line
====
Or strong line
____
Or dotted line
..My title..
Enjoy!
"
note right
  This is working also in notes
  You can also add title in all these lines
  ==Title==
  --Another title--
end note

@enduml

Headings

@startuml
usecase UC1 as "
= Extra-large heading
Some text
== Large heading
Other text
=== Medium heading
Information
....
==== Small heading"
@enduml

Legacy HTML

Some HTML tags are also working:

<b> for bold text
<u> or <u:#AAAAAA> or <u:colorName> for underline
<i> for italic
<s> or <s:#AAAAAA> or <s:colorName> for strike text
<w> or <w:#AAAAAA> or <w:colorName> for wave underline text
<color:#AAAAAA> or <color:colorName>
<back:#AAAAAA> or <back:colorName> for background color
<size:nn> to change font size
<img:file> : the file must be accessible by the filesystem
<img:http://plantuml.com/logo3.png> : the URL must be available from the Internet

@startuml
:* You can change <color:red>text color</color> 
* You can change <back:cadetblue>background color</back> 
* You can change <size:18>size</size> 
* You use <u>legacy</u> <b>HTML <i>tag</i></b> 
* You use <u:red>color</u> <s:green>in HTML</s> <w:#0000FF>tag</w>
----
* Use image : <img:http://plantuml.com/logo3.png>

Table

It is possible to build table.

@startuml
skinparam titleFontSize 14
title
  Example of simple table
  |= |= table |= header |
  | a | table | row |
  | b | table | row |
end title
[*] --> State1
@enduml

You can specify background colors for cells and lines.

@startuml
start
:Here is the result
|= |= table |= header |
| a | table | row |
|<#FF8080> red |<#80FF80> green |<#8080FF> blue |
<#yellow>| b | table | row |;
@enduml

Tree

You can use |_ characters to build a tree.

@startuml
skinparam titleFontSize 14
title
  Example of Tree
  |_ First line
  |_ **Bom(Model)**
	|_ prop1
	|_ prop2
	|_ prop3
  |_ Last line
end title
[*] --> State1
@enduml

Special characters

It's possible to use any unicode characters with &# syntax or <U+0000>

@startuml
usecase foo as "this is ∞ long"
usecase bar as "this is also <U+221E> long"
@enduml

OpenIconic

OpenIconic is an very nice open source icon set. Those icons have been integrated into the creole parser, so you can use them out-of-the-box.

You can use the following syntax: <&ICON_NAME>.

@startuml
title: <size:20><&heart>Use of OpenIconic<&heart></size>
class Wifi
note left
  Click on <&wifi>
end note
@enduml

The complete list is available on OpenIconic Website, or you can use the following special diagram:

@startuml
listopeniconic
@enduml
