## Main
### 0.9.0-rc.0
## [0.12.0](https://github.com/mhanberg/temple/compare/v0.11.0...v0.12.0) (2023-06-13)
### ⚠ BREAKING CHANGES
* configure runtime attributes function ([#202](https://github.com/mhanberg/temple/issues/202))
### Features
* configure runtime attributes function ([#202](https://github.com/mhanberg/temple/issues/202)) ([dc57221](https://github.com/mhanberg/temple/commit/dc57221bc99e165530134559097b27b1dfe95dbe))
### Bug Fixes
* **docs:** typos ([7a50587](https://github.com/mhanberg/temple/commit/7a505875af6a1cee1536e516528f5be914df1f3f))
## v0.11.0
### Breaking Changes
- Rendering slots is now done by passing the assign with the slot name to the `slot` keyword instead of name as an atom. If this slot has multiple definitions, you can loop through them and render each one individually, or render them all at once. Please see the migration guide for more information.
- The `:default` slot has been renamed to `:inner_block`. This is to be easily compatible with HEEx/Surface. Please see the migration guide for more information.
- Capturing the data being passed into a slot is now defined using the `:let!` attribute. Please see the migration guide for more information.
### Enhancements
- Temple components are now compatible with HEEx/Surface components! Some small tweaks to the component implementation has made this possible. Please see the guides for more information.
- Multiple instances of the same slot name can now be declared and then rendered inside the component (similar to HEEx and Surface).
- You can now pass arbitrary data to slots, and it does not need to be a map or a keyword list. I don't think this is a breaking change, but please submit an issue if you notice it is.
- Slot attributes. You can now pass data into a slot from the definition site and use it at the call site (inside the component).
- Dynamic attributes/assigns. You can now pass dynamic attributes to the `:rest!` attribute in a tag, component, or slot.
### Fixes
- Attributes with runtime values that evaluate to true or false will be rendered correctly as boolean attributes.
### 0.10.0
### Enhancements
- mix temple.convert task to convert HTML into Temple syntax.
- Temple now works with SVG elements.

## Passing Data Through Slots
## Passing data to and through Slots
Sometimes it is necessary to pass data from a component definition back to the call site.
Sometimes it is necessary to pass data _into_ a slot (hereby known as *slot attributes*) from the call site and _from_ a component definition (hereby known as *slot arguments*) back to the call site. Dynamic slot attributes can be passed using the `:rest!` attribute in the same way you can with tag attributes.
Let's look at what a `table` component could look like.
Let's look at what a `table` component could look like. Here we observe we access an attribute in the slot in the header with `col.label`.
This example is taken from the HEEx documentation to demonstrate how you can build the same thing with Temple.
Note: Slot attributes can only be accessed on an individual slot, so if you define a single slot definition, you still need to loop through it to access it, as they are stored as a list.

# Converting HTML
If you want to use something like [TailwindUI](https://tailwindui.com) with Temple, you're going to have to convert a ton of vanilla HTML into Temple syntax.
Luckily, Temple provides a mix task for converting an HTML file into Temple syntax and writes it to stdout.
## Usage
First, we would want to create a temporary HTML file with the HTML we'd like to convert.
> #### Hint {: .tip}
>
> The following examples use the `pbpaste` and `pbcopy` utilities found on macOS. These are used to send your clipboard contents into stdout and put stdout into your clipboard.
```shell
$ pbpaste > temp.html
```
Then, we can convert that file and copy the output into our clipboard.
```shell
$ mix temple.convert temp.html | pbcopy
```
Now, you are free to paste the new temple syntax into your project!

# Migrating from 0.10 to 0.11
Most of the changes in this release are related to tweaking Temple's component model to align with HEEx & Surface.
## Rendering Slots
Slots are now available as assigns in the component and are rendered as such.
### Before
```elixir
def my_component(assign) do
temple do
span do
slot :a_slot
end
end
end
```
### After
```elixir
def my_component(assign) do
temple do
span do
slot @a_slot
end
end
end
```
## :default slot has been renamed to :inner_block
The main body of a component has been renamed from `:default` to `:inner_block`.
Note: The "after" example also includes the necessary change specified above.
### Before
```elixir
def my_component(assign) do
temple do
span do
slot :default
end
end
end
```
### After
```elixir
def my_component(assign) do
temple do
span do
slot @inner_block
end
end
end
```
## Passing data into slots
The syntax for capturing data being passed from the call site of a slot to the definition of a slot (or put another way, from the definition of a component to the call site of the component) has changed.
You now capture it as the value of the `:let!` attribute on the slot definition.
### Before
```elixir
def my_component(assign) do
temple do
c &my_component/1 do
slot :a_slot, %{some: value} do
"I'm using some #{value}"
end
end
end
end
```
### After
```elixir
def my_component(assign) do
temple do
c &my_component/1 do
slot :a_slot, let!: %{some: value} do
"I'm using some #{value}"
end
end
end
end

# Migrating from 0.8 to 0.9
TODO: explain it
First off, Temple now requires Elixir 1.13 or higher. This is because of some changes that were brought to the Elixir parser.
## Whitespace Control
To control whitespace in an element, Temple will now control this based on whether the `do` was used in the keyword list syntax or the do/end syntax.
In 0.8, you would do:
```elixir
span do
"hello!"
end
# <span>
# hello!
# </span>
# The ! version of the element would render it as "tight"
span! do
"hello!"
end
# <span>hello!</span>
```
In 0.9, you would do:
```elixir
span do
"hello!"
end
# <span>
# hello!
# </span>
span do: "hello!"
# <span>hello!</span>
```
## Components
Components are no longer module based. To render a component, you can pass a function reference to the `c` keyword. You also no longer need to define a component in a module, using the `Temple.Component` module and its `render` macro.
In 0.8, you would define a component like:
```elixir
defmodule MyAppWeb.Component.Card do
import Temple.Component
render do
div class: "border p-4 rounded" do
slot :default
end
end
end
```
And you would use the component like:
```elixir
div do
c MyAppWeb.Component.Card do
"Welcome to my app!"
end
end
```
In 0.9, you would define a component like:
```elixir
defmodule MyAppWeb.Components do
import Temple
def card(assigns) do
temple do
div class: "border p-4 rounded" do
slot :default
end
end
end
end
```
And you would use the component like:
```elixir
div do
c &MyAppWeb.Components.card/1 do
"Welcome to my app!"
end
end
```
We can observe here that in 0.9 the component is just any 1-arity function, so you can define them anywhere and you can have more than 1 in a single module.
### defcomp
Now that components are just functions, you no longer need this special macro to define a component in the middle of the module.
This can simply be converted to a function.
## Phoenix
All Phoenix related items have moved to the [temple_phoenix](https://github.com/mhanberg/temple_phoenix) package. Please see that library docs for more details.

## Attributes
Attributes are declared as a keyword list.
Temple leverages `Phoenix.HTML.attributes_escape/1` internally, so you can refer to it's documentation for all of the details.
- Keys with underscores are converted to the kebab syntax.
- Values can be Elixir expressions.
- Values that are compile time `true` will be emitted as a boolean attribute. `disabled` and `checked` are examples of boolean attributes.
- Values that are compile time `false` will not be emitted into the document at all.
- The class attribute has a special "object syntax" that allows you to specify classes as a keyword list, only emitting classes that evaluate to true into the final class.
### Dynamic Attributes
Let's look at an example.
To render dynamic attributes into a tag, you can pass them with the reserved attribute `:rest!`.
```elixir
assigns = %{highlight?: false, user_name: "Mitch"}
assigns = %{
data: [data_foo: "hi"]
}
temple do
div id: "hero" do
h2 class: "font-bold", do: "Profile"
section data_controller: "hero" do
p class: ["border": @highlight?] do
"Name: #{@user_name}"
end
video autoplay: true, src: "https://example.com/rick-rolled.mp4"
end
div id: "foo", rest!: @data do
"Hello, world!"
end
end
```
...will emit markup that looks like...
will render to
```html
<div id="hero">
<h2 class="font-bold">Profile</h2>
<section data-controller="hero">
<p class="">
Name: Mitch
</p>
</section>
<video autoplay src="https://example.com/rick-rolled.mp4"></video>
<div id="foo" data-foo="hi">
Hello, world!
</div>
```
## Elixir Expressions
### They Just Work
Any Elixir expression can be used anywhere inside of a Temple template. Here are a few examples.

defmodule Temple.Component do
@moduledoc """
Use this module to create your own component implementation.
This is only required if you are not using a component implementation from another framework,
like Phoenix LiveView.
At it's core, a component implmentation includes the following functions
- `component/2`
- `inner_block/2`
- `render_slot/2`
These functions are used by the template compiler, so you won't be calling them directly.
## Usage
Invoke the `__using__/1` macro to create your own module, and then import that module where you
need to define define or use components (usually everywhere).
We'll use an example that is similar to what Temple uses in its own test suite..
```elixir
defmodule MyAppWeb.Component do
use Temple.Component
defmacro __using__(_) do
quote do
import Temple
import unquote(__MODULE__)
end
end
end
```
Then you can `use` your module when you want to define or use a component.
```elixir
defmodule MyAppWeb.Components do
use MyAppWeb.Component
def basic_component(_assigns) do
temple do
div do
"I am a basic component"
end
end
end
end
```
"""
