Description

Hello, Is this possible?

E.g.

(selmer/add-tag! :getter
                 (fn [args context-map]
                   (let [field (first args)]
                     (str (if (= (:javaType field) "boolean") "is" "get") (:name field)))))

... or using a filter instead of the tag. And in the template:

{% for field in model.fields %}
    {% getter field %}
{% endfor %}

Research direction
Investigate the Selmer documentation and source code (likely in src/selmer/tags.clj or similar) to determine if custom tags receive the template context as a parameter. Check existing tests and examples to see if passing variables is supported. If not, implement a feature to pass the template context to custom tag functions.
