variable and html tag

[Mohammad]

I have a macro as bellow. It uses a helper macro to split input into several words using space as delimiter

• Macro
  

\define _split-fadeIn-class()

<$list filter="$(cls)$ +[splitbefore[ ]]" variable="fcls">

mr-fadeIn-<<fcls>>

</$list>

\end

\define colorful(param1)

<$vars cls="$param1$">

<span class=<<_split-fadeIn-class>> >

 This is test

</span>

</$vars>

\end

• I call it like below
  

<<colorful "redcls bluecls">>

It seems this line does not work correctly:

<span class=<<_split-fadeIn-class>> >

• Any idea?
  

Cheers

At first glance you are not closing <<__ with __>>

Thete may me more, but start there.

It looks like you're trying to concatenate with this:

mr-fadeIn-<<fcls>>




But that probably won't work (I know, it looks like it works when you call _split-fadeIn-class, but that's an illusion) You probably either need to call another macro to concatenate
mr-fadeIn- and <<fcls>> or you need to use wikify to put them together.

Hello Mark,

 The real usage is the macro colorful is called with a list of classes like red and bold.

It then calls a helper macro to split the cls parameter "red bold" and makes mr-fadeIn-red and mr-fadeIn-bold.

to create  .

I donot have problem with concatenation. I think the span tag does not work here as the macro does not work correctly!

When you do this:

mr-fadeIn-<<fcls>>




You're trying to concatenate "mr-fadeIn" with <<fcls>> . In my experience, this kind of concatenation never works. You always need something like mr-fadeIn-$fcls$ or
mr-fadeIn-$(fcls)$ (via a separate macro) or you need to pass it to a wikify widget (<$wikify text="mr-fadeIn<<fcls>>" .../>




Good luck

Hi Tony,

 I did not get what you mean!

Mark,

 Take a look at below solution

\define m1(p)

<$set name=cls filter="$p$ +[splitbefore[ ]] +[addprefix[mr-fadeIn-]]">

<span class=<<cls>> > This is a test </span>

</$set>

\end

<style>

.mr-fadeIn-red{color:red;}

.mr-fadeIn-yellow{background-color:yellow;}

</style>

<<m1 "red yellow">>

This works! What is your opinion?

This is another version!

\define fin() $(cls)$ mr-contents

\define m1(p)

<$set name=cls filter="$p$ +[splitbefore[ ]] +[addprefix[mr-fadeIn-]]">

<span class=<<fin>> > This is a test </span>

</$set>

\end

<style>

.mr-fadeIn-red{color:red;}

.mr-fadeIn-yellow{background-color:#dadada;}

.mr-contents{border:1px solid blue;padding:5px;}

</style>

<<m1 "red yellow">>

Best

In these two recent examples, you are not concatenating anything. So everything works. In your first post, your macro was attempting to concatenate.

Try rewriting colorful like this:

\define colorful(param1)
<$vars cls="$param1$">

<$wikify text=<<_split-fade-In-class>> name=joinme>
<span class=<<joinme>> >
 This is test
</span>
</$wikify>
</$vars>
\end

In my test, when I inspect "This is a test", it now shows classes "mr-fadeIn-redcls mr-fadeIn-bluecls".

Good luck!
