[tw] Re: TW5 - Simple macro question: If fieldvalue is empty, true or false then render ...
Hi
For anyone who has followed this thread - or just found it and wants to see
how the solution ended up looking like - here's a glimpse at the code:
\define if(value:"_false_",test,true,else,error)
<$vars value="""$value$""" test="""$test$""">
<$set name="result" filter="[!prefix[_false_]]" value="compare"
emptyValue="if-error">
<$macrocall $name=<> value=<> test=<> true="""$true$"""
else="""$else$""" error="""$error$""" />
\end
\define compare(value,test,true,else,error)
<$vars value="""$value$""" test="""$test$""" true="""$true$"""
else="""$else$""">
<$set name="result" filter="[prefix]" value=<>
emptyValue=<>>
<>
\end
\define if-error(value,test,true,else,error:"undefined")
//$error$//
\end
\define male() <$macrocall $name="if" value={{!!gender}} test="he" true="male"
else="female" error="choose gender"/>
\define g() <$macrocall $name="if" value={{!!gender}} test="he" true="he"
else="she"/>
\define G() <$macrocall $name="if" value={{!!gender}} test="he" true="He"
else="She"/>
\define g2() <$macrocall $name="if" value={{!!gender}} test="he" true="him"
else="her"/>
\define G2() <$macrocall $name="if" value={{!!gender}} test="he" true="Him"
else="Her"/>
\define g'() <$macrocall $name="if" value={{!!gender}} test="he" true="his"

\define G'() <$macrocall $name="if" value={{!!gender}} test="he" true="His"

Hi Måns
We are getting closer. Here’s some brain-candy for you:
What your gray cells missed was the fact that every variant would need a
check-macro. Bit that was too complicated anyway.
Now I have generalized the check so it takes a second parameter called
"nextmacro" to define the following macro. The check itself was therefore
renamed to "gendercheck".
This worked for me.
Wish you a relaxing weekend!

Hi Thomas
I'm afraid some kind of "neuronic" overloading is what is happening to my
brain :-)
I tried this to get closer to what I want. I'm afraid it doesn't work this
way:
\define He-She-check(gendervalue:"_false_")

\end
\define he-she(gendervalue)

Part 2: Assigning other values by calling a macro via a variable.
Code:
---
\define He-She-check(gendervalue:"_false_")
<$vars value="""$gendervalue$""">
<$set name="result" filter="[!prefix[_false_]]" value="He-She"
emptyValue="no-value">

\define He-She(gendervalue)

\define no-value(gendervalue)
gender is not defined
\end
<$checkbox field="gender" checked="he" unchecked="she"> male
output: <$macrocall $name="He-She-check" gendervalue={{!!gender}}/>
---
In the check-macro we test, if the value is not empty in the same way as
before.
According to the test result we assign the name of the next macro we want to
call.
If we have a value, we go to the He-She macro and check, if the value is "he".
Then we generate a maching output "He" or "She".
O.k. for your brain?
All the best!

Try this:

<$set name="result" filter="[!prefix[_false_]]" value=<>
emptyValue="it">

Hi again Måns,
Now this time we are going to solve thad riddle!
Try this and I try to explain gor your brain ;–)
---
\define he-she-it(gendervalue:"_false_")
<$vars value="""$gendervalue$""">
<$set name="result" filter="[!prefix[_false_]]" value=<>
emptyValue="it">
result: <>
\end
<$checkbox field="gender" checked="he" unchecked="she"> male
output: <$macrocall $name="he-she-it" gendervalue={{!!gender}}/>
---
It all starts with the macrocall instead of the shorter <>
syntax. Frankly, I don’t know why.
If the input for the macro is empty, we assign the value "_false_" (maybe this
works only with the macrocall syntax).
We assign the input value to a variable so we can use it in the filter later.
The result is the output of a filter: if the input value does not (!) equal
"false" we assign the input value. Else the filter returns empty and we assign
"it". (You can of course change that to "gender unknown" if you like.)
Finally we generate the output starting with "result: …"
Hope that helps. More to come …
Cheers,
Thomas

Hi Thomas Thank you very much for answering :-) If I do it like this: \define he-she-it(gendervalue:"_false_") <$vars value="""$gendervalue$"""> <$set name="result" filter="[!prefix[_false_]]" value=<> emptyValue="it" > <> \end <$checkbox field="gender" checked="he" unchecked="she"><> Nothing is shown when the field is either empty or doesn't exist. It shows "he" when "he" is the value and "she" if "she" is the value. It doesn't seem to do anything except rendering the fieldvalue when I use it like this.. Actually I don't need the neutral state - just: he, she, He, She, his, her. His Her computed from the state value (true or false) of a field (gender) (If the field does not exist a default value like: "gender not known" would suffice. For convience I want to use short macros like <>, <>, <> and <> to render different results.. To me it seems like it should/would be some very simple (understandable) macro I should be able to string together with a few conditional "if's" here and there and wikitext... However I've been trying to do this in a TW for some years now - and I always have to give up because it gets to complicated for my (brain) usage :-) It always ends up with shooting sparrows with cannons eg: using Library tiddlers and what not ...
