increment a value in iteration in java stringtemplate

Question

I have my array as below in java string template:

$colors:{ color |
<p>$color.name$
}$

Output is :

Green
Black

The output is want is:

1. Green
2. Black

How do I achieve this? How to get the incremented counter in antlr.stringtemplate ?

Answer 1

I think this is more an HTML issue.

<ol>$colors:{ color |
<li>$color.name$</li>
}$
</ol>

The output:

<ol>
<li>Green</li>
<li>Black</li>
</ol>

As viewed:

1. Green
2. Black

In general numbering (i. ii. iii. iv. ea) and such can be done with CSS styles, or even JavaScript in HTML.

Answer 2

You can use built-in attribute $i$ to start enumeration from one, or $i0$ - from zero.

$colors:{ color |
<p>$i$.&nbsp;$color.name$
}$

Please, also see another example usage in ST3 GIT repo.
