Update text field using the checkbox widget

[kebi]

Hello everyone,

I have a tiddler where I display all the tiddlers that contain the word "TODO " in their text field with a checkbox button.

When I click the checkbox button the text field of the corresponding tiddler should change and include the "~~" symbols as prefix and suffix.

I have accomplished this with the following code:

\define line-through()

<$action-setfield text="~~$(text-field)$~~"/>

\end

<$list filter="[regexp:text[^TODO ]]">

<$set name="text-field" value={{!!text}}>

<$checkbox checkactions=<<line-through>> >

{{!!text}}

</$checkbox>

</$set>

</$list>

But I have problems with removing the "~~" prefix and suffix when unchecking the checkbox.

Does anybody know what's the best way to do this?

Kebi,

Why don't use style at display time? Why do you add them to text field?

I believe you should separate these two content from style.

By the way the removesuffix/removeprefixx filter operators shall do what you want

Hi @kebi,

for the uncheckactions you could use something like:

\define uncheckactions()

<$set name="splitregexp" value="[\^~~][~~$]">
<$action-setfield text={{{ [[$(text-field)$]splitregexp<splitregexp>] }}}/>
</$set>

\end

No, that doesn't work, sorry for my premature proposal

With the current prerelease you could do:

<$set name="splitregexp" value="[\^~~][~~$]">

<$action-setfield text={{{ [[$(text-field)$]search-replace:g:regexp<splitregexp>,[]] }}}/>
</$set>

This could work:

\define line-through()
    <$action-setfield text="~~$(text-field)$~~"/>
\end

\define uncheckactions()
<$set name="splitregexp" value="[\^~~][~~$]">

<$set name="splittext" value={{{ [[$(text-field)$]search-replace:g:regexp<splitregexp>,[]] }}}>
<$action-setfield text=<<splittext>>/>
</$set>
</$set>
\end

<$list filter="[regexp:text[^TODO |^~~TODO ]]">

    <$set name="text-field" value={{!!text}}>

        <$checkbox field="text" checked={{{ [<currentTiddler>get[text]prefix[~~]] }}} unchecked={{{ [<currentTiddler>get[text]!prefix[~~]] }}}  checkactions=<<line-through>> uncheckactions=<<uncheckactions>>>
            {{!!text}}
        </$checkbox>
    </$set>
</$list>

Thank you @Mohammad, I forgot to say that I need to change the value of the tiddler and not only its appearance.

Thank you @BurningTreeC, your solutions works within the current prerelease!
