Append a string containing space to a field

[damien Dupont]

Hello everyone,

I recently discovered this fabulous tool (Tiddly wiki) and I'm trying to customize it to my needs.

However I need some help from Tiddly experts.

I would like to store in the field of a tiddler the content of a table row. In my tiddler, I put an edit-text field and a button to add a new word to the field (and then to the row).

To do this, I decided to separate each word composing my row with "!". For example the field "myrow" will contains : "firstelement!secondelement!thirdelement"

To add to this field a new word, I use a filter to insert it. It works but I have a problem with element with space (ex : "fourth element") -> it will be cut where the space is.

Here is the filter I use to rewrite the "myrow" field :

[all[current]get[myrow]split[!]append[fourth element]join[!]]

Do you have an idea how to explain to tiddly wiki to consider "fourth element" as 1 string only ? or do you have another solution ?

I'm not so familiar with the filter syntax, if you have ressources to help me, it could be great also.

Thanks

Hi Damien,

maybe this trick works for you:

[all[current]get[myrow]split[!]append[fourth_element]join[!]split[_]join[ ]]

Thanks for your help but in fact, in my case "fourth element" represents a variable that contains an input of the user (through the edit-text) and that can contains spaces inside.

Hi again,

you don't need a filter for this, see this example-button:

\define get-concatenated-value()
$(myrow)$!$(userInput)$
\end

<$button>
<$set name="myrow" value={{!!myrow}}>
<$set name="userInput" value={{!!input}}>
<$action-setfield $tiddler=<<currentTiddler>> $field="myrow" $value=<<get-concatenated-value>>/>
</$set>
</$set>
OK
</$button>

Yeah, you're right, I didn't think to use a macro XD I will try tomorrow and I will let you know if it fits to my case ;) Thanks

It works perfectly !! Do you have an idea how to avoid writing the first "!" when the field is empty (before the first user entry) ?

Because when the table is made afterward, it creates a blank cell.

I have found by myself, I just have to ignore blank when I use the list to make the table :

<$list filter="[all[current]get[date]split[!]!is[blank]]" variable="val">

Thanks again for your help ;)
