I'm porting Smarty 2 templates to be compatible with Smarty 3 (latest rev).

I just got this error:
Code:
Code: 0
Error: Syntax Error in template "/var/...l/index.html" on line 214 " <li><a href="/newsletter/">{$NewsletterSubscription }</a></li>" - Unexpected " }", expected one of: "}" , " "
File: /var/.../sysplugins/internal.templatecompilerbase.php
Line: 264

It fails on the space after $NewsletterSubscription. It's nicer not to have spaces at the end of the if-statement, but should it be a Syntax Error?

There more. In Smarty 2 this worked:
Code:
{if ! $smarty.foreach.languages.last} - {/if}


Smarty 3 throws this:
Code:
Code: 0
Error: Syntax Error in template "/var/.../index.html" on line 317 " {if ! $smarty.foreach.languages.last} - {/if}" - Unexpected " ", expected one of: INTEGER , "+" , "-" , "(" , "[" , "$" , "identifier" , "(!,NOT)" , """ , "'" , "boolean" , "null" , "#"
File: /var/.../sysplugins/internal.templatecompilerbase.php
Line: 264


I fixed it by removing the whitespace between the exclamation mark and the variable (which gives prettier code).

Please note that in Samrty3 you can control with with spaces if the standard delimiters ({ and }) used for a Smarty tag or if they are part of javascript.

{something} is a Smarty tag
{ something } is not interpreted by Smarty, for example in Javascript code

The later allows the use of { and } in Javascript without the need to put {literal} tags around it.

There are some other cases where Smarty 3 currenty does not like withespaces where Smarty 2 did. It is an open task to make the lexer/parser of Smarty 3 more tolerant for whitspaces.
