Salt

Salt ist ein Unterprojekt, das in PlantUML enthalten ist und das beim Entwickeln von graphischen Oberflächen nützlich ist.

Man kann entweder das Schlüsselwort @startsalt oder @startuml gefolgt von einer Zeile mit dem Schlüsselwort salt verwenden.

Salt (Wireframe)

Salt is a subproject included in PlantUML that may help you to design graphical interface or Website Wireframe or Page Schematic or Screen Blueprint.

The goal of this tool is to discuss about simple and sample windows.

You can use either @startsalt keyword, or @startuml followed by a line with salt keyword.

Standard-Steuerelemente

Ein Fenster muss mit einer geschweiften Klammer beginnen und enden. Darin kann folgendes definiert werden:
  • ein Button mit [ und ].
  • Radio-Button mit ( und ).
  • eine Checkbox mit [ und ].
  • Freitextfeld mit ".

@startsalt
{
  Just plain text
  [This is my button]
  ()  Unchecked radio
  (X) Checked radio
  []  Unchecked box
  [X] Checked box
  "Enter text here   "
  ^This is a droplist^
}
@endsalt

Das Ziel dieses Werkzeugs ist das Darstellung von einfachen und Beispiel-Fenstern.

Basic widgets

A window must start and end with brackets. You can then define:

  • Button using [ and ].
  • Radio button using ( and ).
  • Checkbox using [ and ].
  • User text area using ".
  • Droplist using ^.

@startsalt
{
  Just plain text
  [This is my button]
  ()  Unchecked radio
  (X) Checked radio
  []  Unchecked box
  [X] Checked box
  "Enter text here   "
  ^This is a droplist^
}
@endsalt

Nutzung von Gittern

Eine Tabelle wird automatisch erstellt, wenn ein öffnende Klammer { benutzt wird.

Zum trennen von Spalten wird | verwendet.

Ein Bespiel:

@startsalt
{
  Login    | "MyName   "
  Password | "****     "
  [Cancel] | [  OK   ]
}
@endsalt

Gleich nach der öffnenden Klammer kann durch das erste Zeichen angegeben werden, ob die Linien des Gitters gezeichnet werden sollen:

Symbol Result
# Um alle senkrechten und waagerechten Linien anzuzeigen
! Alle senkrechten Linien
- Alle waagerechten Linien
+ Alle äusseren Linien

@startsalt
{+
  Login    | "MyName   "
  Password | "****     "
  [Cancel] | [  OK   ]
}
@endsalt

Using grid [|]

A table is automatically created when you use an opening bracket {. And you have to use | to separate columns.

For example:

@startsalt
{
  Login    | "MyName   "
  Password | "****     "
  [Cancel] | [  OK   ]
}
@endsalt

Just after the opening bracket, you can use a character to define if you want to draw lines or columns of the grid :

Symbol Result
# To display all vertical and horizontal lines
! To display all vertical lines
- To display all horizontal lines
+ To display external lines

@startsalt
{+
  Login    | "MyName   "
  Password | "****     "
  [Cancel] | [  OK   ]
}
@endsalt

Group box [^]

@startsalt
{^"My group box"
  Login    | "MyName   "
  Password | "****     "
  [Cancel] | [  OK   ]
}
@endsalt

[Ref. QA-5840]

Verwendung von Trennern

Sie können mehrere horizontale Linien als Trenner verwenden.

@startsalt
{
  Text1
  ..
  "Some field"
  ==
  Note on usage
  ~~
  Another text
  --
  [Ok]
}
@endsalt

Using separator [.., ==, ~~, --]

You can use several horizontal lines as separator.

@startsalt
{
  Text1
  ..
  "Some field"
  ==
  Note on usage
  ~~
  Another text
  --
  [Ok]
}
@endsalt

Baum Widget ( Tree Widget )

Um einen Baum zu erhalten, beginnen Sie mit {T und verwenden + um die Hierarchie Tiefe zu kennzeichnen.

@startsalt
{
{T
 + World
 ++ America
 +++ Canada
 +++ USA
 ++++ New York
 ++++ Boston
 +++ Mexico
 ++ Europe
 +++ Italy
 +++ Germany
 ++++ Berlin
 ++ Africa
}
}
@endsalt

Tree widget [T]

To have a Tree, you have to start with {T and to use + to denote hierarchy.

@startsalt
{
{T
 + World
 ++ America
 +++ Canada
 +++ USA
 ++++ New York
 ++++ Boston
 +++ Mexico
 ++ Europe
 +++ Italy
 +++ Germany
 ++++ Berlin
 ++ Africa
}
}
@endsalt

Tree table [T]

You can combine trees with tables.

@startsalt
{
{T
+Region        | Population    | Age
+ World        | 7.13 billion  | 30
++ America     | 964 million   | 30
+++ Canada     | 35 million    | 30
+++ USA        | 319 million   | 30
++++ NYC       | 8 million     | 30
++++ Boston    | 617 thousand  | 30
+++ Mexico     | 117 million   | 30
++ Europe      | 601 million   | 30
+++ Italy      | 61 million    | 30
+++ Germany    | 82 million    | 30
++++ Berlin    | 3 million     | 30
++ Africa      | 1 billion     | 30
}
}
@endsalt

And add lines.

@startsalt
{
..
== with T!
{T!
+Region        | Population    | Age
+ World        | 7.13 billion  | 30
++ America     | 964 million   | 30
}
..
== with T-
{T-
+Region        | Population    | Age
+ World        | 7.13 billion  | 30
++ America     | 964 million   | 30
}
..
== with T+
{T+
+Region        | Population    | Age

}
..
== with T#

Klammerung

Subelemente können durch Klammern definiert werden.

@startsalt
{
Name         | "                 "
Modifiers:   | { (X) public | () default | () private | () protected
                [] abstract | [] final   | [] static }
Superclass:  | { "java.lang.Object " | [Browse...] }
}
@endsalt

Enclosing brackets [{, }]

You can define subelements by opening a new opening bracket.

@startsalt
{
Name         | "                 "
Modifiers:   | { (X) public | () default | () private | () protected
                [] abstract | [] final   | [] static }
Superclass:  | { "java.lang.Object " | [Browse...] }
}
@endsalt

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>.

@startsalt
{
  Login<&person> | "MyName   "
  Password<&key> | "****     "
  [Cancel <&circle-x>] | [OK <&account-login>]
}
@endsalt

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

Include Salt "on activity diagram"

You can read the following explanation.

@startuml
(*) --> "
{{
salt
{+
<b>an example
choose one option
()one
()two
[ok]
}
}}
" as choose

choose -right-> "
{{
salt
{+
<b>please wait
operation in progress
<&clock>
[cancel]
}
}}
" as wait
wait -right-> "
{{
salt
{+
<b>success
congratulations!
[ok]

}}" as $x
!endprocedure

!procedure _choose()
{+
<b>an example
choose one option
()one
()two
[ok]
}
!endprocedure

!procedure _wait()
{+
<b>please wait
