NAME

tt - Preprocess Perl code with Template Toolkit and Module::Compile.

SYNOPSIS

        use tt ( subs => [qw/foo bar gorch/] );

        [% FOREACH subname IN subs %]
        sub [% subname %] {
                warn "Hi, i'm [% subname %]";
        }
        [% END %]

        no tt;

DESCRIPTION

This module uses Module::Compile to help you generate Perl code without using BEGIN/eval tricks and reducing readability, but without having to repeat yourself either.

CONFIGURATION

To configure Template either subclass this module and override default_tt_config, or pass parameters in the use tt line.

Note that due to the way Module::Compile works you must put all the variables on one use line.

For example:

        use tt INCLUDE_PATH => "/foo";

The default configuration values are:

                INTERPOLATE        => 0,
                EVAL_PERL          => 1,
                INCLUDE_PATH       => [ @INC ],
                LOAD_PERL          => 1,
                DEBUG              => "undef",

This provides a default that is slightly more suitable for templating code than normal TT defaults. DEBUG_UNDEF ensures that no undef variables are interpolated, INTERPOLATE being off ensures that perl variables aren't treated as TT variables by accident, and the other options allow for a more permissive use of features.

VARIABLES

Like configuration parameters, you may pass variables on the use tt line.

Variables and configuration options are destingushed - anything that is all upper case in the use line is considered configuration.

A probably better way to declare variables is simply in the template itself:

        [% foo = "bar" %]

CAVEATS

Due to Module::Compile's semantics the use line is actually fudged and string-evaled by this module, so it might break and you can't refer to lexicals.

TODO

Add all sorts of useful variables about the package that the template is processing, the file and line numbers, etc.

Currently Module::Compile doesn't provide enough facilities for this.
