Exception on missing key about bbmustache HOT 5 CLOSED

Thanks a lot!

from bbmustache.

It can be implemented.
However, the behaviour is against the specification of mustache (mustache is specified as complementing with empty string if key does not exist).

So, I'm not positive about that it will included in bbmustache.

Do you need it for debugging purposes?
For example, I think that worth considering that it will print logs when compile option enabled.

The manual says:

By default a variable "miss" returns an empty string. This can usually be configured in your Mustache library. The Ruby version of Mustache supports raising an exception in this situation, for instance.

I think it is a useful feature. We're building a dynamic set of keys from options, so it would be another manual step to double check all keys used in templates before rendering. It could also be a source of bugs in case the template is changed and someone adds a key but forgets to add a check for it.

Ok, let's implement the same function as raise_on_context_miss of mustache for ruby.
Wait for a few days.

specifications

• It does NOT throw exceptions at parse.
• If raise_on_context_miss enabled, it throw exceptions on missing keys of all tags (e.g. #, >, ^, &)
• However, it does NOT throw exceptions on skipped keys. (e.g. {{#parent}}{{child}}{{/parent}}, parent is false and child is not exist)

This feature was added in v1.5.0.
