Smarty

[foxyprom]

I've started using it Smarty Version -> 3.1.34-dev-7

I have following problem, Custom Left, Right delimiter (in comment).

$smarty->auto_literal = false;
$smarty->left_delimiter = "{%";
$smarty->right_delimiter= "%}";

Comment {* comment *} || without Custom delimiter

Comment {%* comment *%} || with Custom delimiter (It only works that way)

there is any setting for this;

example
$smarty->left_comment = "{*";
$smarty->right_comment = "*}";
Or something similar

No, Smarty delimiters are core of template parsing, everything else based on them.
I.e., Smarty comment is asterisks within delimiters.
Before you change them, please read something about them and why you DON'T need to change them, in most cases.
