According to the changelog there's now support for basic math inside the functions. I saw the examples in the manual and tried to do the following:
spacer should be: {$pcatcount * 3}

where $pcatcount is 3.

I get the following error:
Fatal error: Smarty: [in header.tpl line 259]: syntax error: invalid attribute name: '*' (Smarty_Compiler.class.php, line 1412) in /home/sagi/smarty/Smarty-2.6.0-RC1/libs/Smarty_Compiler.class.php on line 2040

Do I need to enable the math support anywhere?

The problem is the spaces--as far as the parser is concerned, any whitespace ends the expression. Thus, your issue can be solved simply with

[sagi]

I understand.

Funny because the example at: http://smarty.php.net/manual/en/language.math.php actually uses whitespace.

[boots]

So it does! To be honest, I'm not sure if this is the expected behviour or not--I only know that in practice, those whitespaces don't work. Which is sort of inline with other features such as modifiers which also don't permit whitespace.

On the other hand, if this was a vote, I would vote for whitespace support both in maths and modifiers. I don't think it would be overly hard to do (I did a trivial patch for 2.5.0 that introduced whitespace into modifiers awhile back) though it would undoubtedly be yet another thing to slow the parser down. I doubt it would have much affect but I remember that people were sensitive to my suggestion for whitespace in modifiers.

At any rate, either the functionality for math should change or the manual should be updated.

whitespaces work in {math} but not in simple math. they are two totally different things.

[sagi]

I know. But the example for *simple math* uses whitespace.

[messju]

aah, i see. i fixed this in cvs. the fixed examples will become online with 2.6.0-RC2.

[sagi]

how can i do something like:
rowspan: {$products|@count*2-1}

i get a fatal error when doing that, i also tried {`$products|@count`*2-1}

[boots]

AFAIK, you will have to do an intermediate assignment of the count value:

[sagi]

Or maybe I should just keep using the math function for that?

I saw that right now it runs those regex/evals everytime i use the math function so it probably makes it very slow. I also saw the alternative in one of the forums here, are there any plans to make the alternative the default in future releases? if not, can i safely replace the original math with it?

[boots]

IIR, the new builtin math in 2.6+ (as opposed to the plugin math) runs those regex's only at compile time, much like the plugin compile time math function in the plugin forum that you mention. My recollection is that the compile time math function will not end up as part of the distribution, but it should still work if you need it.

I was trying to use a simple counter inside a section statement, but when I try to perform math on the index variable I am getting string cat'ing.

Basic configuration info:
Smarty V 2.5.0
Alternate delimiters '{{' and '}}'

Example of what I am trying to do:

[boots]

Simple math is not supported in 2.5.0. Instead of using {assign}, use the {math} plugin instead.

Thanks Boots,

I decided to rethink the data that I was passing to the smarty template after reading in the manual about the {math} action. Words like "slow" are bad. heh.

Thanks again.

you don't need a counter in your example above.
use {$smarty.section.i.index},
