Macro with variable number of attributes (parameter)

[Mohammad]

The TW macro can accept the optional parameter! An optional parameter is the one you can send its value on macro call or you can ignore and macro will use some default value!

My question is can we have a macro with variable number of parameters (attributes)

See below macro

\define mypic(caption:"no caption", img)

<figure>

[img[$img$]]

<figcaption style="text-align:center;font-weight:700;">$caption$</figcaption>

</figure>

\end

I want to call mypic as below

<<mypic caption img>>

and

<<mypic caption img1 img2 img3>>

What do you think?

I know JS has this capability, see below

You could pass a list in quotes, like:

\define stuff(myvar mylist)
I saw $myvar$. Then <br/>
<$list filter="[enlist[$mylist$]]">
<$view field="title"/><br/>
</$list>
\end

Marks Idea of passing a list is a great one, and more elegant than this suggestion

However if there is a theoretical maximum you can just define it with img1 img2... img10 and include the logic to process only the ones provided (have a value).
