Fix templates not being correctly populated when caller location label has a prefix.

Allan Pires, Jason Kim
Use component path for generating RSpec files.

When generating new RSpec files for components, the generator will use the view_component_path value in the config to decide where to put the new spec file. For instance, if the view_component_path option has been changed to app/views/components, the generator will put the spec file in spec/views/components. If the view_component_path doesn't start with app/, then the generator will fall back to spec/components/.

This feature is enabled via the config.view_component.generate.use_component_path_for_rspec_tests option, defaulting to false. The default will change to true in ViewComponent v4.

We're so grateful for all the work of community members to get us to this release. Whether it’s filing bug reports, designing APIs in long-winded discussion threads, or writing code itself, ViewComponent is built by the community, for the community.

<% end %>

This configuration option defaults to false but will be enabled in 3.0 and the old behavior will be removed.

```
class MyComponent < ViewComponent::Base
  renders_one :item
  renders_many :items
end
```
Joel Hawksley

2.64.0

Add warn_on_deprecated_slot_setter flag to opt-in to deprecation warning.

In v2.54.0, the Slots API was updated to require the with_* prefix for setting Slots. The non-with_* setters will be deprecated in a coming version and removed in v3.0.

To enable the coming deprecation warning, add warn_on_deprecated_slot_setter:
```
class DeprecatedSlotsSetterComponent < ViewComponent::Base
  warn_on_deprecated_slot_setter

Joel Hawksley, Blake Williams
Revert change making content evaluation consistent.

Blake Williams
Pin rails main dependency due to incompatibility with Global Output Buffer.

Joel Hawksley

2.61.0

Ensure side-effects in content are consistently evaluated before components are rendered. This change effectively means that content is evaluated for every component render where render? returns true. As a result, code that is passed to a component via a block/content will now always be evaluated, before #call, which can reveal bugs in existing components.

Blake Williams

2.60.0

Add support for render_preview in RSpec tests.

Thomas Hutterer

2.59.0

Expose Capybara DSL methods directly inside tests.

The following Capybara methods are now available directly without having to use the page method:

v1.0.1

Always recompile component templates outside production.

Joel Hawksley, John Hawthorn

This release extracts the ActionView::Component library from the GitHub application.

It will be published on RubyGems under the existing actionview-component gem name, as @chancancode has passed us ownership of the gem.
