Here's a macro that provides a work-around interface:
\define input(fieldname)
<$vars
temp="$:/temp/$(currentTiddler)$/$fieldname$"
default={{{ [<currentTiddler>get[$fieldname$]] }}}
placeholder="enter a value for $fieldname$">
<$keyboard key="enter" actions="""
<$action-setfield $tiddler=<<currentTiddler>> $field="$fieldname$"
$value={{{ [<temp>get[text]] }}} />
<$action-deletetiddler $filter="[<temp>]" />
""">
<$edit-text tag="input" tiddler=<<temp>> default=<<default>> placeholder=<<
placeholder>>/>
</$keyboard>
<$button tooltip="delete field"> {{$:/core/images/delete-button}}
<$action-deletefield $tiddler=<<currentTiddler>> $field="$fieldname$"/>
<$action-deletetiddler $filter="[<temp>]" />
</$button>
<$button tooltip="cancel input"> {{$:/core/images/cancel-button}}
<$action-deletetiddler $filter="[<temp>]" />
</$button>
<$button tooltip="save input"> {{$:/core/images/done-button}}
<$action-setfield $tiddler=<<currentTiddler>> $field="$fieldname$" $value
={{{ [<temp>get[text]] }}} />
<$action-deletetiddler $filter="[<temp>]" />
</$button>
</$vars>
\end
How to use it:
* copy the above code into a tiddler (e.g.,
"$:/TiddlyTools/Macros/getinput")
* tag that tiddler with "$:/tags/Macro"
* in any other tiddler, write:
<<input "foo">>
How it works:
* the $edit-text default value is the current value in "SomeField" of
"SomeTiddler"
* the $edit-text input goes into a temporary tiddler named
$:/temp/SomeTiddler/SomeField
* the "delete" button removes "SomeField" from "SomeTiddler"
* the "cancel" button discards the temporary tiddler (automatically
reverting the input contents to showing the default value)
* the "ok" button copies the temporary tiddler content to "SomeField" in
"SomeTiddler"
* the "enter" key is a shortcut for pressing "ok"
I'm also working on an enhanced version where the buttons appear as a
"popup"
only when the $edit-text control gets the input focus, but I'm still
debugging that
version (there's a strange interaction between the focus and the popup that
I
haven't yet figured out).
enjoy,
