If you have a template like this

Code:

<pre>
line 1: {if 1}foo{/if}
line 2: {strip}bar{/strip}
line 3: {math equation="987 * x" x=1}
line 4: {include file="foo.tpl"}
line 5: bongo
</pre>

and another template, foo.tpl, that is completely empty, you get the following output:

Code:

line 1: fooline 2: bar
line 3: 987
line 4: line 5: bongo

It appears that Smarty sometimes but now always "swallows" the newline after }, if } is the last character on the line. If you add an additional space or some other character to the end of the line in the template shown above, the "line x" labels do appear on seperate lines.

I don't know whether "newline swallowing" is intentional like in PHP (I assume it isn't), but it seems weird that not all tags behave the same in this respect.

the idea behing smarty's newline swallowing is: it should work so, that the output looks as expected. Smile

as a rule of thumb: tags that don't have output swallow a following newline but tags that have output keep it.

for example:
start
{foreach from=$list item=a}<-- this newline would be swallowed
{$a}<-- this newline would be kept
{/foreach}<-- this newline would be kept
end

so you get
start
a1
a2
a3
a4
end

that's the theory. i agree that in practice it looks just weird and incosistent.
