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

[Thomas Elmiger]

Hi all 

A new "hack" is ready for you to try – I hope you will find it useful, e.g. to create quizzes or tests, to automate letters, …

This macro offers a solution for simple if-then-else text generation. It presents some added value compared to the reveal widget: it accepts variables as well as text references and it can show an error message. The ifAisB macro comes with full documentation in the tiddler $:/_telmiger/ifAisB – a link to the documentation can also be found below.

Credits and more examples: This solution was inspired by and developed together with Måns who describes his usage of a former version in this post in the Google group. Many others have contributed with relating posts or inspiring ideas. So thank you, TW community!

A shorthand macro to test if the value of a field priority equals "a" could be defined and used like this:

\define check-a() <$macrocall $name="ifAisB" A={{!!priority}} B="a" then="priority is a" else="priority is not a"/>

<<check-a>>

See documentation here: https://tid.li/tw5/hacks.html#ifAisB%20%E2%80%93%20Compare%20if-then-else%20Style%20in%20Wikitext

As always: Do yourself a favour and save a backup before trying my stuff.

Let me know if it works for you.

All the best,
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?

Cheers Måns Mårtensson

Will definitely have a play with this.
Cheers.

Ciao Måns & Thomas

Semi-seriously ... apps that can play games are very inviting.

Personally I need to see more examples of how the ifAisB Macro works to fully get it.

Best wishes
Josiah

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 button to set tags …

Have fun!
Thomas

Thanks Jan,

Other ways* to do similar things have been around for a while – I just try to make solutions as simple as possible for myself :)

I optimized and enhanced the quiz and added a mini-survey where two out of three options must be chosen. Just to demonstrate the potential and to inspire others …

Hope to see more playful stuff from others!

Cheers,
Thomas
