# Changelog

## main

## 3.13.0

* Add ruby head and YJIT to CI.

    *Reegan Viljoen*

* Fixed a bug where inline templates where unable to remove trailing whitespace without throwing an error.

    *Reegan Viljoen*

* Fixed CI for Rails main.

    *Reegan Viljoen*

* Add `from:` option to `use_helpers` to allow for more flexible helper inclusion from modules.

    *Reegan Viljoen*

* Fixed ruby head matcher issue.

    *Reegan Viljoen*

## 3.12.1

* Ensure content is rendered correctly for forwarded slots.

    *Cameron Dutro*

## 3.12.0

* Remove offline links from resources.

    *Paulo Henrique Meneses*

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

  On the upstream version of Ruby, method owners are now included in backtraces as prefixes. This caused the call stack filtering to not work as intended and thus `source_location` to be incorrect for child ViewComponents, consequently not populating templates correctly.

    *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.

    *William Mathewson*

## 3.11.0

### v3.0.0

1,000+ days and 100+ releases later, the 200+ contributors to ViewComponent are proud to ship v3.0.0!

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. We couldn’t be more proud of what we’re building together :heart:

This release makes the following breaking changes, many of which have long been deprecated:

* BREAKING: Remove deprecated slots setter methods. Use `with_SLOT_NAME` instead.

    *Joel Hawksley*

For example:

```diff
<%= render BlogComponent.new do |component| %>
-  <% component.header do %>
+  <% component.with_header do %>
    <%= link_to "My blog", root_path %>
  <% end %>
<% end %>
```

* BREAKING: Remove deprecated SlotsV1 in favor of current SlotsV2.

    *Joel Hawksley*

* BREAKING: Remove deprecated `content_areas` feature. Use Slots instead.

    *Joel Hawksley*

* BREAKING: Remove deprecated support for loading ViewComponent engine manually. Make sure `require "view_component/engine"` is removed from `Gemfile`.

    *Joel Hawksley*

* BREAKING: Remove deprecated `generate_*` methods. Use `generate.*` instead.

    *Joel Hawksley*

* BREAKING: Rename private TestHelpers#controller, #build_controller, #request, and #preview_class to avoid conflicts. Note: While these methods were undocumented and marked as private, they were accessible in tests. As such, we're considering this to be a breaking change.

    *Joel Hawksley*

* Add `config.view_component.use_consistent_rendering_lifecycle` to 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's passed to a component via a block/content will now always be evaluated, before `#call`, which can reveal bugs in existing components. This configuration option defaults to `false` but will be enabled in 3.0 and the old behavior will be removed.

* Add link to [ViewComponentAttributes](https://github.com/amba-Health/view_component_attributes) in Resources section of docs.

    *Romaric Pascal*

* `render_preview` test helper is available by default. It is no longer necessary to include `ViewComponent::RenderPreviewHelper`.

    *Simon Fish*

## 2.65.0

* Raise `ArgumentError` when conflicting Slots are defined.

    Before this change it was possible to define Slots with conflicting names, for example:

    ```ruby
    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](https://viewcomponent.org/CHANGELOG.html#2540), 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`:

    ```ruby
    class DeprecatedSlotsSetterComponent < ViewComponent::Base
      warn_on_deprecated_slot_setter
    end
    ```

    *Joel Hawksley*

* Add [`m`](https://rubygems.org/gems/m) to development environment.

    *Joel Hawksley*

    *Matheus Poli Camilo*

* Fix issue causing helper methods to not be available in nested components when the render monkey patch is disabled and `render_component` is used.

    *Daniel Scheffknecht*

## 2.62.0

* Remove the experimental global output buffer feature.
* Restore functionality that used to attempt to compile templates on each call to `#render_in`.
* Un-pin `rails` `main` dependency.

    *Cameron Dutro*

* Add blank space between "in" and "ViewComponent" in a deprecation warning.

    *Vikram Dighe*

* Add HappyCo to list of companies using ViewComponent.

    *Josh Clayton*

* Add predicate method support to polymorphic slots.

    *Graham Rogers*

## 2.61.1

* Revert `Expose Capybara DSL methods directly inside tests.` This change unintentionally broke other Capybara methods and thus introduced a regression. We aren't confident that we can fail forward so we have decided to revert this change.

    *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*

* Add support for `render_preview` in RSpec tests.

    *Thomas Hutterer*
