[tw] Re: [TW5] Presenting ifAisB Macro: Compare Strings if-then-else Style

[Thomas Elmiger]

Hi Josiah & all,

Here’s a little quiz for you: http://tid.li/tw5/hacks.html#Distances%20Quiz 

I just played a bit with a short quiz macro that uses ifAisB and a buttoun 
to set tags …

Have fun!
Thomas

[tw] Re: My attempt at an editable table

[Ste Wilson]

Another thing I'll have to have a look at soon... Too many great toys to tinker 
with.. 

At the risk of putting a spanner in the works I mostly access my tiddlywikkis 
in my mobile and I don't seem to be able to scroll/ see any of the table off 
screen.

Could it play nice with the Mathcell plugin? 

Stephen.

There was an update from Mark S. in January that covers pretty much the exact 
issue you encountered:

http://tiddlywiki.com/#Concatenating%20text%20and%20variables%20using%20macro%20substitution

Of course, finding such information in the documentation remains hard.

Thanks, Eric.

That's what I needed. And I feel a good less like a moron for not figuring 
that out on my own. 

Jeremy might want to consider expanding the explanation to clarify the 
various syntax at work here.

Within the macro syntax, $(varname)$ expands values that are defined in 
variables **outside the macro definition** (i.e., using <$set> or <$vars>) 
and $varname$ expands values that are **passed as arguments** to the macro 
call.  To reference a variable that has been **defined within the current 
scope** (i.e., the "fieldName" variable defined by the <$list> widget) you 
need to use the <> syntax.

However, because you are passing <> as a parameter to another 
macro, you can't just use <> because the <<...>> syntax doesn't 
"nest". Thus, the following macro syntax does NOT work:
   <>>>

Fortunately, there is an alternative *widget* syntax for making a macro 
call, that does allow you to use the <<...>> syntax to specify parameters:
<$macrocall $name="FieldThing" name=<> />

That should do it.
Let me know how it goes.

[tw] Re: My attempt at an editable table

['Stephen Kimmel' via TiddlyWiki]

Let me pose my question more directly. I assume the answer is obvious to 
the more experienced hands. 

The following code is not working correctly and I don't understand why. I 
would like the macro FieldChoice to return a select widget with a list of 
captions taken from the dictionary tiddler FieldsData. 
I get the Select that works but all the captions match the one for the 
default entry in FieldThing. The problem appears to be passing the 
parameter fieldName from FieldChoice to FieldThing. The code below is just 
one of my many failed attempts.

\define FieldChoice(name:"title")
<$select field="field1" default='title'>
none
<$set name="currentTiddler" value="FieldsData">
<$list filter="[all[current]indexes[]]" variable="fieldName">
>><>




\end

\define FieldThing(name:"current_address")
{{FieldsData##$name$}}
\end

<>

Can someone tell me what I've done wrong and how to do this correctly?

We received a letter from Mrs April Mackenzie of Moscow, Scotland 

 
with a question for people with more experience.

She have successfully tested porridge for taste, firmness and climpt using 
a TiddlyWiki... 



But she had to do the testing inside a flour pancake wrap that she is 
concerned may be distorting the results.

So far she has not found a way to test Naked Porridge through a TiddlyWiki 
and would appreciate any feedback others have.

Hi,

I am confused by the description of the new filter operator suffix has:
*field* as it seems that the examples filter the opposite of what is stated 
in the documentation.
http://tiddlywiki.com/#has%20Operator

To me, the examples make sense, the documentation does not. It would be 
very logical, if the parts marked yellow could be removed/added in the docs:

output 
*suffix field*
» those input tiddlers in which field F does *not* exist 
! output  

*suffix field*
» those input tiddlers in which field F *does not* exists
Am I missing something?

This is just a detail – many thanks for the great new version anyway!!!

Cheers, 
Thomas

Hi Thomas

Great, great, great :-)
Well done!!

With the new 5.1.14 editions new features - dnd etc. - your macro could 
help start a veritable lavine of games for TiddlyWiki!!
Card games, dnd questions to answers with instant feedback etc., etc   

Maybe we should announce a "create games & quizzes challenge" to speed up 
things?

Yes, absolutely, you’d be very welcome. Your project should precipitate an 
excellent discussion.

To stress this is not a developer-focussed meeting. GitHub works pretty well 
for TiddlyWiki developers to collaborate with each other. The things that I 
think worked well at the last meetup included:

* Discussing TiddlyWiki’s nature/purpose/direction/goals etc.
* Show and tell, where people demonstrated how they use TiddlyWiki in their 
everyday life
* Developers demonstrating the capabilities of stuff they’ve built
* Developers collaborating with non-developers to build/adapt stuff (we worked 
on TWederation last time)

I’d be very interested to hear more about the Dyslexia project.

Best wishes
