Hi,
Right now when rendering and passing in a scalar/object variable or a single
list, it is necessary to wrap things into an array to give twig a variable name:
$this->templating->render($template, array('article' => $article));
$this->templating->render($template, array('article_list' => $articles));
imho it would be nicer if one could just write:
$this->templating->render($template, $article);
$this->templating->render($template, $articles);
In order to be able to do this twig could simply always define an implicit
variable, f.e. "params", that points to all the parameters passed, whatever
they were.
Now obviously for a numerically indexed list this would not work as we cannot
define variables with numbers as names. However the solution is to simply not
define any variables in that case aside from the "params".
$article = new Article();
$this->templating->render($template, $article);
would allow for
{{ params.title }}
array(new Article(), new Article());
$this->templating->render($template, $articles);
would allow for
{{ params[0].title }}
array('foo' => new Article(), 'bar' => new Article());
$this->templating->render($template, $articles);
would allow for
{{ params[0].title }}
{{ foo.title }}
{{ bar.title }}
This would essentially be fully BC, except that this new variable would be
defined, but which if passed as a key would likely be overwritten.
$this->templating->render($template, array('params' => 'foo'));
would result in outputting 'foo'
{{ params }}
So in practice the only BC break would be
$this->templating->render($template, array('bar' => 'foo'));
{% if params is defined %}
Also note that the name "params" is just a proposal. Maybe it should rather be
"twig.params" and "$php_params", which would further reduce the chances of a BC
break.
