This module provides a library of standard functions for templates using |
154
|
|
|
|
|
|
|
Text::TemplateLite. |

|
158
|
|
|
|
|
|
|
The functions in this section can be called from Perl code. The other |
159
|
|
|
|
|
|
|
sections describe functions that can be added to and called from |
160
|
|
|
|
|
|
|
L template engines. |

|
|
|
|
|
|
|
This registers the specified functions or function-group tags with the |
165
|
|
|
|
|
|
|
specified template engine. It returns the template engine. |
166
|
|
|
|
|
|
|
|
167
|
|
|
|
|
|
|
The template engine must respond to the method |
168
|
|
|
|
|
|
|
L<"register($name, $definition)">, where C<$definition> is a coderef |
169
|
|
|
|
|
|
|
expecting three parameters: the name of the function as called from |
170
|
|
|
|
|
|
|
the template, an arrayref of parameter code sequences, and an object |
171
|
|
|
|
|
|
|
instance compatible with L. |

This function allows you to retrieve variable values from the most recent |

external template call. |

Parameters are interpreted as as many pairs as possible. The first |
917
|
|
|
|
|
|
|
parameter in each pair is a variable name in the current template; the |
918
|
|
|
|
|
|
|
second is a variable name in the external template whose value will be |
919
|

assigned to the variable in the current template. |
920
|
|

If there are an odd number of parameters, the value of the external |
922
|

|
|
variable named last will be the return value of the function call. Otherwise, |
923

no value is returned. |
