Shopify liquid template debugging

Question

I am trying to debug a Shopify theme.

I am a ruby dev, so understand the code.

But seems, if my liquid tags are in error than Shopify just ignores it/goes back to the previous version in production.

Any ideas how I can debug a live production theme's liquid template?

Something that may help you or others coming to this question is using Shopify's themekit for offline development. This will catch syntax errors on upload, for example:

    10:25:19 [development] Received Update event on templates/product.liquid
    10:25:19 [development]Asset Perform Update to templates/product.liquid at host yourshop.myshopify.com
    Status: 422 Unprocessable Entity
    Errors: Liquid syntax error (line 7): Unknown tag 'not_a_tag'

There is a good, though slightly outdated now, tutorial here . To note, when he mentions downloading the shopify_theme gem, that is now not maintained and you should use themekit instead.
