Parse and Evaluate Liquid Expressions Independently of Templates

[kutchar]

I’m interested in using this crate to parse and evaluate Liquid expressions independently of a full Template. Specifically, I’d like to evaluate expressions like "order.price > 100" or "order.price > 100 and order.items_count > 2" and get a boolean result, given an order object.

I wasn’t able to figure out how to achieve this from the existing code or documentation—does the crate support this use case?

Not directly at this time. You could fake it by putting the expression inside of a template but that could allow for "template injections".

Thank you for the quick response! Just out of curiosity, how difficult do you think it would be to:

1. Either add the feature to this crate
2. Or extend the current crate to support this via a separate crate

Shouldn't be too bad to adjust liquid_core::parser to allow parsing of it. Unsure whether anything built on top should live in liquid or not.

Thanks!
