Subject: [PATCH] Fix warning when using yield in templates on ruby 2.7
|
|
|
|
Take the class of the scope, and pass it through the
|
|
compilation methods. Call class_eval on the scope's
|
|
class so that constant lookup works, and switch the
|
|
singleton class opening to instance_exec.
|
|
|
|
This radically simplifies the compiled template method
|
|
code, and I would guess it speeds it up significantly
|
|
as well. However, this approach can cause a memory
|
|
leak if you are creating anonymous classes at runtime
|
|
and then passing instances of those classes as the scope
|
|
of the render.
