! Introduction

The view widget displays the contents of a tiddler field in a specified format.

! Content and Attributes

The content of the `<$view>` widget is displayed if the field or property is missing or empty.

|!Attribute |!Description |
|tiddler |The title of the tiddler (defaults to the [[current tiddler|Current Tiddler]]) |
|field |The name of the field to view (defaults to "text") |
|index |The name of the index to view |
|format |The format for displaying the field (see below) |
|template |Optional template string used when the `format` attribute is set to "date" |
|subtiddler |Optional SubTiddler title when the target tiddler is a [[plugin|Plugins]] (see below) |
|mode |<<.from-version "5.1.15">> Optional transclusion parsing mode for wikified formats. May be "inline" or "block" (the default) |

!! Formats

The following formats can be specified in the `format` attribute:

|!Format |!Description |
|''text'' |Plain text (default) <<.tip "See also the TextWidget. `<$view format=text tiddler=MyTiddler/>` renders the same as `<$text text={{MyTiddler}}/>`">>|
|''htmlencoded'' |The field is displayed with HTML encoding. <<.tip "Rendered value is the same as the output from the [[encodehtml|encodehtml Operator]] filter operator">>  |
|''htmltextencoded'' |<<.from-version "5.2.0">> The field is displayed with HTML encoding, only double quotes (") are not escaped. This creates a more compact htmlencoding appropriate for html text content, but //not// for attributes. |
|''urlencoded'' |The field is displayed with URL encoding <<.tip "Rendered value is the same as the output from the [[encodeuri|encodeuri Operator]] filter operator">> |
|''doubleurlencoded'' |The field is displayed with double URL encoding <<.tip "Rendered value is the same as the output from calling the [[encodeuri|encodeuri Operator]] filter operator twice">> |
|''htmlwikified'' |The field is wikified according to the mode attribute and the resulting HTML returned as plain text (ie HTML elements will appear in plain text) |
|''plainwikified'' |The field is wikified according to the mode attribute and the text content of the resulting HTML returned as plain text (ie HTML elements will be removed) |
|''htmlencodedplainwikified'' |The field is wikified according to the mode attribute and the text content of the resulting HTML returned as HTML encoded plain text (ie HTML elements will be removed) |
|''date'' |The field is interpreted as a UTC date and displayed according to the DateFormat specified in the `template` attribute <<.tip "Rendered value is the same as the output from the [[format:date|format Operator]] filter operator">> |
|''relativedate'' |The field is interpreted as a UTC date and displayed as the interval from the present instant <<.tip "Rendered value is the same as the output from the [[format:relativedate|format Operator]] filter operator">> |
|''stripcomments'' |The field is interpreted as JavaScript source code and any lines beginning `\\#` are stripped |
|''jsencoded'' |The field is displayed as a JavaScript encoded string <<.tip "Rendered value is the same as the output from the [[stringify|stringify Operator]] filter operator">> |

!! "WikiText format"

To display the field content as regular WikiText, for example with working links, use the [[TranscludeWidget]] instead. 

! SubTiddler Access

The view widget allows access to the individual tiddlers stored within a [[plugin|Plugins]].

The following example will view the core version of the tiddler [[$:/DefaultTiddlers]] even if it has been overridden:

<<wikitext-example-without-html '
<$view tiddler="$:/core" subtiddler="$:/DefaultTiddlers"/>

'>>

! Examples

Given this [[Saturday]] example tiddler:

|!tiddler|!raw content|!rendered content|
|[[Saturday]]|<$text text={{Saturday}}/>|{{Saturday}}|

Here is how `<$view tiddler=Saturday format=<<format>>/>` renders for each format:
<table>
<tr><th>format</th><th>renders as</th></tr>
<$list filter="text htmlencoded htmltextencoded urlencoded doubleurlencoded htmlwikified plainwikified htmlencodedplainwikified stripcomments jsencoded" variable=format>
<tr>
<td>''<<format>>''</td>
<td><$view tiddler="Saturday" format=<<format>>/></td>
</tr>
</$list>
</table>
