=head1 NAME
Dist::Zilla::Role::TextTemplate - something that renders a Text::Template template string
=head1 VERSION
version 6.033
=head1 DESCRIPTION
Plugins implementing TextTemplate may call their own C<L</fill_in_string>>
method to render templates using L<Text::Template|Text::Template>.
=head1 PERL VERSION
This module should work on any version of perl still receiving updates from
the Perl 5 Porters. This means it should work on any version of perl
released in the last two to three years. (That is, if the most recently
released version is v5.40, then this module should work on both v5.40 and
v5.38.)
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased. The version may be increased
for any reason, and there is no promise that patches will be accepted to
lower the minimum required perl.
=head1 ATTRIBUTES
=head2 delim
This attribute (which can't easily be set!) is a two-element array reference
returning the Text::Template delimiters to use. It defaults to C<{{> and
C<}}>.
=head1 METHODS
=head2 fill_in_string
my $rendered = $plugin->fill_in_string($template, \%stash, \%arg);
This uses Text::Template to fill in the given template using the variables
given in the C<%stash>. The stash becomes the HASH argument to Text::Template,
so scalars must be scalar references rather than plain scalars.
C<%arg> is dereferenced and passed in as extra arguments to Text::Template's
C<new> routine.
