[TW5] looping through an array in a macro

[Bob Flandard]

Hello,

Is it possible to define an array and pass it as an argument to a user defined macro and then loop through each element of the array within the macro?

Thanks, Bob

Of course, something like that:

\define myMacro(filter)
<$list filter="""$filter$""">
{{!!title}}
</$list>
\end

<<myMacro "[[HelloThere]] [[Macros]] [[ListWidget]]">>

Or, if you need to define your array in another way, with the same macro definition:

<$set name="myArray" filter="[[HelloThere]] [[SetWidget]]">
<$macrocall $name="myMacro" filter=<<myArray>>/>
</$set>

<$list filter="""$filter$""">

I don't think the triple quotes are necessary, i.e enough with single quotes, or?

Hello Evolena,

Thank you for your code suggestion but it's a bit too abstract for my tiny brain. I was thinking of something of the form:

\define myMacro(arg1 arg2)
for i in arg1:
 make a string that does something useful and insert $arg1[i]$ and $arg2[i]$ values
\end

myArray1=[string1, string2, string3]
myArray2=[number1, number2, number3]

<<myMacro 'myArray1' 'myArray2'>>


I could call a macro multiple times with different arguments, but I was hoping to simplify it and do it in a single call passing arrays.

Thanks, Bob

The built-in tools don't work that way. You would probably need to write a widget or a javascript macro if you really want to do something step-wise.

But it if you explain what exactly it is you want to accomplish, there are a lot of clever people in this forum who have thought up all sorts of ways to accomplish complex tasks with the existing toolset.
