NAME

Text::Template::Preprocess - Expand template text with embedded Perl

VERSION

This file documents Text::Template::Preprocess version 1.40

SYNOPSIS

use Text::Template::Preprocess;

my $t = Text::Template::Preprocess->new(...);  # identical to Text::Template

# Fill in template, but preprocess each code fragment with pp().
my $result = $t->fill_in(..., PREPROCESSOR => \&pp);

my $old_pp = $t->preprocessor(\&new_pp);

DESCRIPTION

Text::Template::Preprocess provides a new PREPROCESSOR option to fill_in. If the PREPROCESSOR option is supplied, it must be a reference to a preprocessor subroutine. When filling out a template, Text::Template::Preprocessor will use this subroutine to preprocess the program fragment prior to evaluating the code.

The preprocessor subroutine will be called repeatedly, once for each program fragment. The program fragment will be in $_. The subroutine should modify the contents of $_ and return. Text::Template::Preprocess will then execute contents of $_ and insert the result into the appropriate part of the template.

Text::Template::Preprocess objects also support a utility method, preprocessor(), which sets a new preprocessor for the object. This preprocessor is used for all subsequent calls to fill_in except where overridden by an explicit PREPROCESSOR option. preprocessor() returns the previous default preprocessor function, or undefined if there wasn't one. When invoked with no arguments, preprocessor() returns the object's current default preprocessor function without changing it.

In all other respects, Text::Template::Preprocess is identical to Text::Template.
