Aborting Processing

[Dave Glick]

Hi,

I have two questions about aborting processing/rendering in the
engine. The first is that I'm wondering if it's possible at all. Since
I'll be allowing users to edit templates, I'd like a way to time them
out if they do something like trigger an infinite loop.

The second question I have (which might be answered by the first) is
if there's a way to abort processing from within a tag. I'd like to
provide some switches or "early exit" opportunities for template
authors (something like "this doesn't apply, so don't use this
template"). That would allow the template to serve a dual purpose as
both a template and, when appropriate, like a controller.

If aborting isn't available right now, I'd be happy to take a look and
submit a pull request. Any hints on where the most appropriate place
to put such functionality would be?

Thanks!

Hi Dave,

There's nothing in DotLiquid for this at the moment. That said, couldn't you use the TPL? Something like:

var task = Task.Factory.StartNew(() =>
{

	var template = Template.Parse("{{ user.name }}");

	return template.Render(...);
});

// Use a fixed amount of time, and just give up if we go over that.
task.Wait(1000);

(By the way, thanks for your pull request! I hope to look at it soon.)
