Discussion:
[tw5] Appending text to a tiddler
(too old to reply)

I'm trying to build a button to append text to a tiddler. Thing is, I want
the name of the tiddler to by dynamic. Stephan has the example I'm building
on here: http://skeeve.tiddlyspot.com/ . That code is:

\define appendButton(now, add)
<$button set="Target" setTo="$now$$add$">append</$button>
\end

<$edit-text tiddler="$:/temp/Append"/>
<$macrocall $name="appendButton" now={{Target}} add={{$:/temp/Append}}/>

---
{{Target}}

That appends a tiddler called Target.

My attempt is almost there. I'm able to dynamically set the the tiddler I
want to send the text to and that bit is working but it isn't appending.
I'm trying to figure out how to dynamically set the now={{Target}} bit.

My non working attempt is here.
\define appendButton(target, now, add)
<$button set=$target$ setTo="$now$$add$<br>">append</$button>
\end

<$wikify name="thisproj" text={{!!project}}>
<$wikify name="projnotes" text='<<thisproj>> Notes'>

{{||$:/timer}}

<$edit-text tiddler="$:/temp/Append"/>
<$macrocall $name="appendButton" target="<<projnotes>>" now=<<projnotes>>
add={{$:/temp/Append}}/>

Any ideas appreciated.

Thanks,
Scott

Decided to switch things up and got closer to my goal.
Made a macro:
\define updtTID(param:"", btn-caption:"Add a Note", color:"#8058A5")
<$button style="color:$color$; fill:$color$; margin-bottom:3px;">
{{$:/core/images/new-button}} $btn-caption$


<$wikify name="master" text="{{$param$}}{{$:/temp/Append}}">
<$action-setfield $tiddler="$param$" text=<<master>>/>
<$action-setfield $tiddler="$:/temp/Append" text=""/>
</$wikify>
</$button>
\end

Then calling this macro:
<$wikify name="thisproj" text={{!!project}}>
<$wikify name="projnotes" text='<<thisproj>> Notes'>


<$edit-text tiddler="$:/temp/Append"/>


<<updtTID param:$(projnotes)$>>

Now the only thing missing is a way to add a <br> to the end each time the
text is appended.

Hello Scott!
This is not a very good solution, but works for you!

Change the line

<$wikify name="master" text="{{$param$}}{{$:/temp/Append}}">



with


<$wikify name="master" text="{{$param$}}&#10;&#10;{{$:/temp/Append}}">

Scott,
The problem with your solution is: Some wikitext formatting in your main
tiddler or $:/temp/Append
will not work and every time you use updtTID macro those formatting will
be removed or wikified. For example try to append

This is a ''Text''.

Or

```
y=sx
```

This is another Test. `y` is a variable.



And if for example your main tiddler contains


This text has been transcluded from`test`:{{test}}

After appending, you will not have {{test}} but its wikified value has been
inserted!

Mohammad,
Thanks for the tip on using the code for <br>. It works great.

You make a good point about wikifying the text I am passing. It may not be
a big problem for the simple case I have for this current project but it
does make sense to consider changing my solution.
