I'm aware of the change in whitespace around delimiters in order to allow easier compatibility with JavaScript. However, in our case we used identical left and right delimiters (`) instead of the default '{' and '}'. This had always worked fine in Smarty 2, but upgrading to Smarty 3 generates an error.

The error is on the next line after an include:

Yes, the left and right delimiters must be different.
There is no way around it as Smarty3 does allow nested Smarty tags.
Also you should not use for same reasion backticks as delimiter as they have special meaning inside double quoted strings .

It's also a surprise to me that it did work in Smarty2.

oh, those are nasty delimiters, the "`" is a special character for Smarty inside quotes. Making both delimiters the same character may also be causing problems, but Uwe may respond with a better explanation.

For a quick fix, you could make a prefilter that converts your "`" delimiters to { and } just before compile time, so you don't have to change all your templates. FWIW, I would advise to change the delims and fix the templates with a search/replace.

Fair enough. Might be good to mention in the docs that the delimiters must be different. Indeed identical delimiters mean that the templates cannot be updated with a simple search and replace, so a warning to all you out there who are tempted by the relative simplicity of identical delimiters, a la quotes or Perl regular expressions
