selmer.template-parser
(source) Where we preprocess the inheritance and mixin components of the templates.
These are presumed to be static and we only aggregate them on the first
template render. The compile-time tag parsing routines happen on a flat string
composed from the result of `extends` inheritance and `include` mixins.
