=head1 NAME
-SQL::Translator::Producer::TTSchema -
+SQL::Translator::Producer::TTSchema -
Produces output using the Template Toolkit from a SQL schema
=head1 SYNOPSIS
filename => 'foo_schema.sql',
to => 'TTSchema',
producer_args => {
- ttfile => 'foo_template.tt',
+ ttfile => 'foo_template.tt', # Template file to use
+
+ # Extra template variables
+ tt_vars => {
+ author => "Mr Foo",
+ },
+
+ # Template config options
+ tt_conf => {
+ INCLUDE_PATH => '/foo/templates',
+ },
},
);
print $translator->translate;
Produces schema output using a given Template Tookit template.
-It needs one additional producer_arg of C<ttfile> which is the file
-name of the template to use. This template will be passed a single
-argument called C<schema>, which is the
-C<SQL::Translator::Producer::Schema> object, which you can then use to
-walk the schema via the methods documented in that module.
+It needs one additional producer arg of C<ttfile> which is the file
+name of the template to use. This template will be passed a variable
+called C<schema>, which is the C<SQL::Translator::Producer::Schema> object
+created by the parser. You can then use it to walk the schema via the
+methods documented in that module.
Here's a brief example of what the template could look like:
See F<t/data/template/basic.tt> for a more complete example.
-You can also set any of the options used to initiallize the Template object by
-adding them to your producer_args. See Template Toolkit docs for details of
+The template will also get the set of extra variables given as a
+hashref via the C<tt_vars> producer arg. (Note that the old style of
+passing this config in the C<ttargs> producer arg has been
+deprecated).
+
+You can set any of the options used to initialize the Template object by
+adding a C<tt_conf> producer arg. See Template Toolkit docs for details of
the options.
+(Note that the old style of passing this config directly in the C<ttargs> producer args
+has been deprecated).
