Any \f(CW\*(C`Template::Context\*(C'\fR options may be passed to the Template \&\fBnew()\fR constructor method and will be forwarded to the \&\f(CW\*(C`Template::Context\*(C'\fR constructor. .PP .Vb 1 \& use Template; \& \& my $template = Template\->new({ \& TRIM => 1, \& EVAL_PERL => 1, \& BLOCKS => { \& header => \*(AqThis is the header\*(Aq, \& footer => \*(AqThis is the footer\*(Aq, \& }, \& }); .Ve .PP Similarly, the \f(CW\*(C`Template::Context\*(C'\fR constructor will forward all configuration parameters onto other default objects (e.g. Template::Provider, Template::Plugins, Template::Filters, etc.) that it may need to instantiate. .PP .Vb 4 \& $context = Template::Context\->new({ \& INCLUDE_PATH => \*(Aq/home/abw/templates\*(Aq, # provider option \& TAG_STYLE => \*(Aqhtml\*(Aq, # parser option \& }); .Ve .PP A \f(CW\*(C`Template::Context\*(C'\fR object (or subclass) can be explicitly instantiated and passed to the Template \fBnew()\fR constructor method as the \&\f(CW\*(C`CONTEXT\*(C'\fR configuration item. .PP .Vb 2 \& use Template; \& use Template::Context; \& \& my $context = Template::Context\->new({ TRIM => 1 }); \& my $template = Template\->new({ CONTEXT => $context }); .Ve .PP The Template module uses the Template::Config \&\fBcontext()\fR factory method to create a default context object when required. The \f(CW$Template::Config::CONTEXT\fR package variable may be set to specify an alternate context module.

A reference to a list of constructor arguments may be passed as the second parameter.

The default \s-1LOAD_FILTERS\s0 provider is a Template::Filters object. .PP Additional arguments may be passed by list reference along with an optional alias under which the filter will be cached for subsequent use. The filter is cached under its own \f(CW$name\fR if \f(CW$alias\fR is undefined. Subsequent calls to \&\f(CW\*(C`filter($name)\*(C'\fR will return the cached entry, if defined.

In the latter case, the error string is promoted to a Template::Exception object of '\f(CW\*(C`undef\*(C'\fR' type. This method also accepts a reference to the current output buffer which is passed to the Template::Exception constructor, or is appended to the output buffer stored in an existing Template::Exception object, if unique (i.e. not the same reference). By this process, the correct state of the output buffer can be reconstructed for simple or nested throws. .ie n .SS "define_block($name, $block)" .el .SS "define_block($name, \f(CW$block\fP)" .IX Subsection "define_block($name, $block)" Adds a new block definition to the internal \s-1BLOCKS\s0 cache. The first argument should contain the name of the block and the second a reference to a Template::Document object or template sub-routine, or template text which is automatically compiled into a template sub-routine. .PP Returns a true value (the sub-routine or Template::Document reference) on success or undef on failure. The relevant error message can be retrieved by calling the \fBerror()\fR method. .ie n .SS "define_filter($name, \e&filter, $is_dynamic)" .el .SS "define_filter($name, \e&filter, \f(CW$is_dynamic\fP)" .IX Subsection "define_filter($name, &filter, $is_dynamic)" Adds a new filter definition by calling the \&\fBstore()\fR method on each of the \s-1LOAD_FILTERS\s0 providers until accepted (in the usual case, this is accepted straight away by the one and only Template::Filters provider). The first argument should contain the name of the filter and the second a reference to a filter subroutine. The optional third argument can be set to any true value to indicate that the subroutine is a dynamic filter factory. .PP Returns a true value or throws a '\f(CW\*(C`filter\*(C'\fR' exception on error. .ie n .SS "define_vmethod($type, $name, $code)" .el .SS "define_vmethod($type, \f(CW$name\fP, \f(CW$code\fP)" .IX Subsection "define_vmethod($type, $name, $code)" This method is a wrapper around the Template::Stash \&\fBdefine_vmethod()\fR method.
