Search terms module: e. This example:. On Win32 platforms a filename may by prefixed by a drive letter and colon. For example:. A number of standard plugins are defined e. The recommended convention is to specify these plugin names in lower case. The Template Toolkit first looks for an exact case-sensitive match and then tries the lower case conversion of the name specified.
The USE directive is used to create plugin objects and does so by calling the plugin method on the current Template::Context object. The context then calls the load class method which should return the class name default and general case or a prototype object against which the new method can be called to instantiate individual plugin objects. This allows regular Perl modules i. They must provide a new class method for instantiating objects but it will not receive a reference to the context as the first argument.
Plugin modules should provide a load class method or inherit the default one from the Template::Plugin base class which is called the first time the plugin is loaded. Regular Perl modules need not. In all other respects, regular Perl objects and Template Toolkit plugins are identical. If a particular Perl module does not conform to the common, but not unilateral, new constructor convention then a simple plugin wrapper can be written to interface to it.
These are added to the standard filters which are available by default. Filters specified via this option will mask any standard filters of the same name. The corresponding value should contain a reference to an array containing a subroutine reference and a flag which indicates if the filter is static 0 or dynamic 1. A filter may also be specified as a solitary subroutine reference and is assumed to be static. The method accepts a filter name, a reference to a filter subroutine and an optional flag to indicate if the filter is dynamic.
Static filters are those where a single subroutine reference is used for all invocations of a particular filter. Filters that don't accept any configuration parameters e. The subroutine reference is simply returned when that particular filter is requested. The subroutine is called to filter the output of a template block which is passed as the only argument. The subroutine should return the modified text.
Filters that can accept parameters e. In this case, the subroutine is taken to be a filter 'factory' that is called to create a unique filter subroutine each time one is requested.
A reference to the current Template::Context object is passed as the first parameter, followed by any additional parameters specified. The subroutine should return another subroutine reference usually a closure which implements the filter. Each provider can return a compiled template, an error, or decline to service the request in which case the responsibility is passed to the next provider.
If none of the providers can service the request then a 'not found' error is returned. The Template::Context plugin method queries each provider in turn in a "Chain of Responsibility" as per the template and filter methods. By default, a single Template::Plugins object is created using the current configuration hash. Configuration items destined for the Template::Plugins constructor may be added to the Template constructor. The Template::Context filter method queries each provider in turn in a "Chain of Responsibility" as per the template and plugin methods.
By default, any errors are reported as such, with the request for the particular resource template , plugin , filter being denied and an exception raised. This allows a subsequent provider to take responsibility for providing the resource, rather than failing the request outright. A reference to a Template::Service object, or sub-class thereof, to which the Template module should delegate.
If unspecified, a Template::Service object is automatically created using the current configuration hash. A reference to a Template::Context object which is used to define a specific environment in which template are processed.
A Template::Context object is passed as the only parameter to the Perl subroutines that represent "compiled" template documents. Template subroutines make callbacks into the context object to access Template Toolkit functionality, for example, to INCLUDE or PROCESS another template include and process methods, respectively , to USE a plugin plugin or instantiate a filter filter or to access the stash stash which manages variable definitions via the get and set methods.
A reference to a Template::Stash object or sub-class which will take responsibility for managing template variables. The Template::Parser module implements a parser object for compiling templates into Perl code which can then be executed. A default object of this class is created automatically and then used by the Template::Provider whenever a template is loaded and requires compilation.
This allows a modified or entirely new template language to be constructed and used by the Template Toolkit. Source templates are compiled to Perl code by the Template::Parser using the Template::Grammar by default to define the language structure and semantics. Compiled templates are thus inherently "compatible" with each other and there is nothing to prevent any number of different template languages being compiled and used within the same Template Toolkit processing environment other than the usual time and memory constraints.
These files are provided, along with a small script to rebuild the grammar, in the parser sub-directory of the distribution. You don't have to know or worry about these unless you want to hack on the template language or define your own variant. There is a README file in the same directory which provides some small guidance but it is assumed that you know what you're doing if you venture herein.
If you grok LALR parsers, then you should find it comfortably familiar. It's very nice. Click to hide the menu and go all widescreen! Contents Top Close Open. The output generated is rather long so we'll show it split across two lines:. Without the uri filter the output would look like this also split across two lines. In this rather contrived example we've manage to generate both a broken URL the repeated?
So don't do that. Always use the uri filter to encode your URL parameters. However, you should not use the uri filter to encode an entire URL. Instead you should use the url note spelling filter for this purpose. Please note that this behaviour was changed in version 2. Prior to that, the uri filter did not encode the reserved characters, making it technically incorrect according to the RFC specification since superceded by RFC and RFC So we fixed it in 2.
As of version 2. The ability to use the RFC character set was added in 2. The url filter is a less aggressive version of the uri filter. Indents the text block by a fixed pad string or width. The ' pad ' argument can be specified as a string, or as a numerical value to indicate a pad width spaces. Defaults to 4 spaces if unspecified. Truncates the text block to the length specified, or a default length of
