Generally, I use the {( )} format to supply parameters to a function, like:
[(somefunc param1={(otherfunc)})]
Because the var funcs {( )} are processed early, they can be plugged
into other functions.
I use the <( )> either in an if clause or cases where I want the
function processed late, as in a search fmt.
[if ! admin]<(forward other.page)>[if]
If I used either of the other formats, they would be forwarded before
the if statement was ever checked.
or
[(search group=test* fmt="<(somefunc {+p})>")]
The first function returns a long string of somefunc lines, which are
then processed later by the markup engine.
These are the main rules. For most functions I just use the standard
[( )]. For fuction parameters, use the var func format. For functions
inside an if statement or that need special late processing, use <(
)>.
Hope this helps.
If some cares to copy this to a tutorial or doc page somewhere it
would be helpful, even if the instructions are skimpy, they are better
than nothing.
Cheers,
Dan
