Introduction

New in: 5.1.23The action-confirm widget is an action widget that prompts the user for confirmation and invokes other action widgets contained within it only if the user confirms. ActionWidgets are used within triggering widgets such as the ButtonWidget.

Content and Attributes

The action-confirm widget is invisible. Any content within it is only processed if the user confirms the action, or the confirmation has been disabled by the $prompt attribute.

Examples

Here is an example of a button that asks the user for confirmation, before deleting the caption and tags fields of the current tiddler:

<$button>
<$action-confirm $message="Do you wish to delete the caption and tags?">
<$action-deletefield caption tags/>
Delete "caption" and "tags"
</$action-confirm>
</$button>

Here is an example of a button that uses the optional $prompt attribute to control whether to prompt the user before deleting the text field of the tiddler HelloThere:

<$button>
<$action-confirm $message="Do you wish to delete the text field?" $prompt={{$:/state/promptUser}}>
<$action-deletefield $tiddler="HelloThere" $field="text"/>
</$action-confirm>
Delete text from ~HelloThere
</$button>

Introduction

The $action-createtiddler widget is an action widget that creates new tiddlers. Action widgets are used within triggering widgets such as the ButtonWidget.

There are several differences from the tm-new-tiddler message:

• The new tiddler is not automatically displayed in the story river
• The title of the new tiddler is made available for subsequent operations

Content and Attributes

The action-createtiddler widget is invisible.

Variables

New in: 5.2.0 The content of the $action-createtiddler widget is executed after the new tiddler has been created. The title of the newly created tiddler is stored in the variable createTiddler-title.

Examples

copy to clipboard

Caption for new button: <$edit-text tiddler="$:/state/new-button-caption" tag="input" default=""/>

<$button>
<$action-createtiddler $basetitle="Homemade Button" tags="$:/tags/PageControls" text={{$:/state/new-button-caption}}>
<$action-navigate $to=<<createTiddler-title>>/>
</$action-createtiddler>
Create a new non-functional page control button and open the tiddler
</$button>

That renders as:

Caption for new button:

Create a new non-functional page control button and open the tiddler

This example will create "New Tiddler", "New Tiddler 1", " New Tiddler 2" and so on

\define testCreate()
<$action-createtiddler />
\end

<$button actions=<<testCreate>> >
Create Tiddler
</$button>

Create Tiddler - Clicking this button, will also open the Right sidebar: Recent tab

This example will use the base title defined in $:/language/DefaultNewTiddlerTitle.

It will overwrite the tiddler, if the button is clicked several times.

\define testCreate()
<$action-createtiddler $basetitle={{$:/language/DefaultNewTiddlerTitle}} $overwrite="yes"/>
\end

<$button actions=<<testCreate>> >
Create Tiddler
</$button>

Create Tiddler - Clicking this button, will also open the Right sidebar: Recent tab

This example will uses a base-title and a template: ActionCreateTiddlerWidget Template

It will create: "base", "base 1", "base 2" and so on

\define testCreate()
<$action-createtiddler $basetitle="base" $template="ActionCreateTiddlerWidget Template"/>
\end

<$button actions=<<testCreate>> >
Create Tiddler
</$button>

Create Tiddler - Clicking this button will also open the Right sidebar: Recent tab

This example uses a base-title "base" and a template: ActionCreateTiddlerWidget Template.

There will be new fields "aa" and "bb" which are added to the new tiddlers.

\define testCreate()
<$action-createtiddler $basetitle="base" $template="ActionCreateTiddlerWidget Template" aa="new field aa" bb="new field bb" />
\end

<$button actions=<<testCreate>> >
Create Tiddler
</$button>

Create Tiddler - Clicking this button will also open the Right sidebar: Recent tab

This example will use the base title defined in ActionCreateTiddlerWidget Template.

It will create: "base", "base 1", "base 2" and so on, and navigate to this tiddler in draft mode.

\define testCreate()
<$action-createtiddler $basetitle="base" $template="ActionCreateTiddlerWidget Template">
	<$action-sendmessage $message="tm-edit-tiddler" $param=<<createTiddler-title>>/>
</$action-createtiddler>
\end

<$button actions=<<testCreate>> >
Create Tiddler
</$button>

Create Tiddler - Clicking this button, will also open the Right sidebar: Recent tab

Introduction

The action-deletetiddler widget is an action widget that deletes tiddlers. ActionWidgets are used within triggering widgets such as the ButtonWidget.

There are several differences compared to the WidgetMessage: tm-delete-tiddler:

• The user is not prompted to confirm the deletion
• No automatic updating of the story list
• No special handling of draft tiddlers

Content and Attributes

The action-deletetiddler widget is invisible. Any content within it is ignored.

Examples

Here is an example of a button that deletes the tiddler HelloThere:

<$button>
<$action-deletetiddler $tiddler="HelloThere"/>
Delete "~HelloThere"
</$button>

Here is an example of a button that deletes all tiddlers tagged TableOfContents:

<$button>
<$action-deletetiddler $filter="[tag[TableOfContents]]"/>
Delete tiddlers tagged "~TableOfContents"
</$button>

Introduction

The action-listops widget is an action widget that manipulates user lists in any field or data index. ActionWidgets are used within triggering widgets such as the ButtonWidget.

Content and Attributes

The action-listops widget is invisible. Any content within it is ignored.

$filter vs. $subfilter

Standalone use of the $subfilter attribute can be replaced by using a (more complicated) $filter attribute value.

For example, the items "abc" and "123" can be appended to the field myfield using the $subfilter attribute:

<$action-listops $field="myfield" $subfilter="abc 123"/>

The same can be achieved using the $filter attribute and prepending the Filter Run [all[current]get[myfield]enlist-input[]] to the Filter Expression:

<$action-listops $field="myfield" $filter="[all[current]get[myfield]enlist-input[]] abc 123"/>

The short form is more convenient, but the long form is useful for live-debugging complicated $subfilter values using the filter tab of $:/AdvancedSearch. By using $:/AdvancedSearch, the Filter Expression can be tested before using action-listops to modify actual tiddler fields. For this use case, the all[current] portion of the expression needs to be changed to select the proper test tiddler.

$tags vs. $field + $subfilter

Tagging is implemented using a tiddler's 'tags' field, so appending the tags "abc" and "123" using the $tags attribute like this:

<$action-listops $tags="abc 123"/>

is mostly equivalent to using $subfilter along with "tags" for the value of $field:

<$action-listops $field="tags" $subfilter="abc 123"/>

$action-listops widget vs. $action-setfield widget

The ActionSetFieldWidget replaces a field's value using $field/$value attributes. A single ActionSetFieldWidget can be used to set any number of fields by using attributes not starting with $.

The ActionListopsWidget replaces or modifies a single field's value. The new value is generated using filters.

The following two examples are functionally equivalent:

<$action-setfield $field="myfield" $value="abc 123"/>

<$action-listops $field="myfield" $filter="abc 123"/>

In general, ActionSetFieldWidget is better for setting multiple fields at once and for replacing a field's value. The ActionListopsWidget is better for modifying a field based on the field's existing value and for using a Filter Expression to derive the value.

Extended Filter Operators

A number of extended filter operators are necessary for the manipulation of lists. These operators have been designed primarily for use in subfilter expressions whereby the modified current list is returned in place of the current list.

Examples

In this example we shall populate and then clear a list in an ordinary field (myfield) of this tiddler (the default.)

<$button>
<$action-listops $field="myfield" $subfilter="efg hlm pqr"/>
Populate 'myfield'
</$button>
<$button>
<$action-listops $field="myfield" $subfilter="abc xyz"/>
Append More Items
</$button>
<$button>
<$action-listops $field="myfield" $subfilter="-abc -hlm"/>
Remove Items
</$button>
<$button>
<$action-listops $field="myfield" $filter="[[]]"/>
Clear 'myfield'
</$button>

<$list filter="[list[!!myfield]]">

</$list>

In this example we shall append and remove items from a list in an ordinary field (myfield) of this tiddler (the default) and sort the resultant list. We shall then remove some of the appended items and sort the resulting list in reverse order.

<$button>
<$action-listops $field="myfield" $subfilter="-efg ijk xyz [[this is a title]] +[sort[]]"/>
Mangle List
</$button>
<$button>
<$action-listops $field="myfield" $subfilter="-xyz -[[this is a title]] +[!sort[]]"/>
Unmangle List
</$button>

<$list filter="[list[!!myfield]]">

</$list>

In this example we shall append a few tags to the 'tags' field of this tiddler (the default.) We shall then remove some of the appended tags.

<$button>
<$action-listops $tags="+[append{Days of the Week!!short}] $:/tag1 $:/tag2 $:/tag3"/>
Populate 'tags'
</$button>
<$button>
<$action-listops $tags="+[!remove:2{!!tags}]"/>
Remove Last Two Tags
</$button>
<$button>
<$action-listops $tags="+[!prefix[$:/]]"/>
Remove System Tags
</$button>
<$button>
<$action-listops $tags="-Mon -Tue"/>
Remove Mon and Tue
</$button>
<$button>
<$action-listops $tags="+[prefix[$:/]] ActionWidgets Widgets"/>
Remove User Tags
</$button>
<$button>
<$action-listops $tags="+[[]] ActionWidgets Widgets"/>
Clear Tags
</$button>

<$list filter="[list[!!tags]]">

</$list>

Introduction

The action-navigate widget is an action widget that sends a tm-navigate message back up the widget tree. ActionWidgets are used within triggering widgets such as the ButtonWidget.

Content and Attributes

The action-navigate widget is invisible. Any content within it is ignored.

Scroll handling

The optional $scroll attribute can be set to "yes" to force scrolling to occur to bring the target tiddler into view. If set to "no" then scrolling does not occur. If the $scroll attribute is omitted then scrolling occurs unless either:

• the control key is pressed
• the action was initiated with the middle mouse button (if available)

Note that if navigating to multiple tiddlers at once you should use the same $scroll setting for all of them.

Examples

Here is an example of button that navigates to two different tiddlers at once:

<$button>
<$action-navigate $to="ButtonWidget"/>
<$action-navigate $to="ActionWidgets"/>
Click me!
</$button>
