! `<$innerwiki>` widget
|
|
|
|
The `<$innerwiki>` widget encapsulates an embedded wiki. It starts as a blank copy of the current wiki and can have additional payload tiddlers added via embedded `<$data>` widgets (see below).
|
|
|
|
It supports the following attributes:
|
|
|
|
|!Attribute |!Description |
|
|
|template |Specifies the template to be used to generate the base wiki (defaults to $:/plugins/tiddlywiki/innerwiki/template) |
|
|
|width |Width in pixels of the virtual screen for rendering the embedded wiki |
|
|
|height |Height in pixels of the virtual screen for rendering the embedded wiki |
|
|
|style |CSS style definitions to be added to the DIV wrapper around the IFRAME containing the embedded wiki |
|
|
|class |CSS classes to be added to the DIV wrapper around the IFRAME containing the embedded wiki |
|
|
|filename |Base filename for saving a screenshot of the embedded wiki under Node.js (excludes file extension) |
|
|
|clipLeft |Position in pixels of the left edge of the clip rectangle (optional) |
|
|
|clipTop |Position in pixels of the top edge of the clip rectangle (optional) |
|
|
|clipWidth |Width in pixels of the clip rectangle (optional) |
|
|
|clipHeight |Height in pixels of the clip rectangle (optional) |
|
|
|
|
! `<$data>` widget
|
|
|
|
The `<$data>` widget is used within the `<$innerwiki>` widget to specify payload tiddlers to be added to the innerwiki.
|
|
|
|
It supports the following attributes:
|
|
|
|
|!Attribute |!Description |
|
|
|$tiddler |The title of a tiddler to be used as a payload tiddler (optional) |
|
|
|$filter |A filter string identifying tiddlers to be used as payload tiddlers (optional) |
|
|
|//any attribute<br>not starting<br>with $// |Field values to be assigned to the payload tiddler(s) |
|
|
|
|
It can be used in three different ways:
|
|
|
|
* Without the `$tiddler` or `$filter` attributes, the remaining attributes provide the fields for a single payload tiddler
|
|
* With the `$tiddler` attribute present, the payload tiddler takes its fields from that tiddler with the remaining attributes overriding those fields
|
|
* With the `$filter` attribute present, the payload is a copy of all of the tiddlers identified by the filter, with the remaining attributes overriding those fields of each one
|
|
|
|
This example injects a copy of the "HelloThere" tiddler with the addition of the field "custom" set to "Alpha":
|
|
|
|
```
|
|
<$data $tiddler="HelloThere" custom="Alpha"/>
|
|
```
|
|
|
|
This example injects all image tiddlers with the addition of the field "custom" set to "Beta":
|
|
|
|
```
|
|
<$data $filter="[is[image]]" custom="Beta"/>
|
|
```
|
|
|
|
! `<$anchor>` widget
|
|
|
|
The `<$anchor>` widget is used within the `<$innerwiki>` widget to specify draggable anchors to be overlaid on the innerwiki.
|
|
|
|
It supports the following attributes:
|
|
|
|
|!Attribute |!Description |
|
|
|x |The title of the tiddler containing the X coordinate of the anchor |
|
|
|y |The title of the tiddler containing the Y coordinate of the anchor |
|
|
|
|
This example declares an anchor whose coordinates are contained in the tiddlers [[my-anchor-x]] and [[my-anchor-y]]:
|
|
|
|
```
|
|
<$anchor x="my-anchor-x" y="my-anchor-y"/>
|
|
```
|
|
|
|
! `screenshot` command
|
|
|
|
Saves PNG screenshots of the `<$innerwiki>` widgets rendered by a set of tiddlers identified by a filter.
|
|
|
|
```
|
|
--screenshot <filter> <deviceScaleFactor>
|
|
```
|
|
|
|
* ''filter'': a filter identifying the tiddlers to be rendered, from which the individual `<$innerwiki>` widgets are screenshotted
|
|
* ''deviceScaleFactor'': a scale factor for the screenshot (optional; defaults to 1)
|
|
|
|
A deviceScaleFactor of 4 or 5 gives high quality screenshots suitable for print use.
