This bridge allows Text::Decorator to make use of Template Toolkit's |
26
|
|
|
|
|
|
|
standard filters. |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
First you need to specify which representations this filter applies to; |
29
|
|
|
|
|
|
|
"all" will convert all representations. Next you give the name of the TT |
30
|
|
|
|
|
|
|
filter, and following that, any arguments to pass to the filter. |
