[Openinteract-dev] TT [PERL] blocks and recursion

[Kutter M. <mar...@si...>]

Hi * !

Recently I had the need to both use [% PERL %] blocks in TT templates and
allow templates to [% INCLUDE %] themselves, i.e. allow TT recursion.

The attached patch makes the use of [% PERL %] blocks configurable by the
directive (patch against OpenInteract2-1.99_04).

[content_generator TT]
eval_perl = 1|0

in the server.ini configuration file. The default is not to allow the
evaluation of [% PERL %] blocks in TT templates (OI2 currently does not
allow Perl blocks).

Recursion can be configured via the 

[content_generator TT]
recursion = 1|0

directive. The default is not to allow recursion (OI2 currently does not
allow recursion).

Making recursion and PERL blocks configurable grealy increases OI2
functionality (especially recursion - some stuff like trees is quite
difficult to display without).

As the default values represent the current OI2 behaviour, the change should
be non-intrusive for existing applications.
