Format definition

Simple link

Simple links are define using two square brackets (or three square brackets for field or method on class diagram).

Example:
  • [[http://plantuml.com]]
  • [[]] (empty link)

Link with optional label

It is possible to give an optional label that will be printed instead of the link itself. A space is used as separator after the URL itself.

Example: [[http://plantuml.com This label is printed]]

Link with optional tooltip

Finally you can also have an optional tooltip using round brackets, just after the URL and before the optional label.

Example: [[http://plantuml.com{Optional tooltip} This label is printed]]

Only tooltip

You can also have only a tooltip using round brackets.

Example: [[{A tooltip}]]

Only tooltip and label

You can also have only a tooltip using round brackets, and a label.

Example: [[{A tooltip} This label is printed]]

URL authentication

With URL authentication it is possible to provide an authentication method, credentials, and a proxy config to URL endpoints.
