### Example of Canonicalization

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Shows how Tailwind CSS classes are transformed. Unknown classes are preserved and sorted to the front.

```diff
- mr-4 custom-btn flex ml-[1rem] flex
+ custom-btn mx-4 flex
```

--------------------------------

### Configure Custom Tailwind CLI Binary and Input

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Specify the path to the `tailwindcss` executable, its working directory, and the CSS entrypoint if not using the default `:tailwind` hex package setup.

```elixir
# .formatter.exs
[
  plugins: [Phoenix.LiveView.HTMLFormatter],
  attribute_formatters: %{class: CanonicalTailwind},
  canonical_tailwind: [
    binary: "node_modules/.bin/tailwindcss",
    input: "css/app.css",
    cd: Path.expand("assets", __DIR__)
  ],
  # ...
]
```

--------------------------------

### Configure `mix format` with Attribute Formatters

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Integrate CanonicalTailwind into your `.formatter.exs` file by adding it to `attribute_formatters` alongside the HEEx formatter.

```elixir
# .formatter.exs
[
  plugins: [Phoenix.LiveView.HTMLFormatter],
  attribute_formatters: %{class: CanonicalTailwind},
  # ...
]
```

--------------------------------

### Configure Pool Size for Parallelization

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Adjust the number of `tailwindcss` CLI processes to parallelize `mix format`. The default is 6. Consider reducing for smaller projects or increasing for larger ones.

```elixir
# .formatter.exs
[
  plugins: [Phoenix.LiveView.HTMLFormatter],
  attribute_formatters: %{class: CanonicalTailwind},
  canonical_tailwind: [pool_size: 3],
]
```

--------------------------------

### Configure Timeout for CLI Initialization

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Increase the timeout for `tailwindcss` CLI initialization if it exceeds the default 30 seconds, especially on slower CI machines or with larger projects. Value is in milliseconds.

```elixir
# .formatter.exs
[
  plugins: [Phoenix.LiveView.HTMLFormatter],
  attribute_formatters: %{class: CanonicalTailwind},
  canonical_tailwind: [timeout: 60_000],
]
```

--------------------------------

### Specify Tailwind Profile in `.formatter.exs`

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

If your project uses multiple Tailwind CSS profiles, explicitly define which profile CanonicalTailwind should use.

```elixir
# .formatter.exs
[
  plugins: [Phoenix.LiveView.HTMLFormatter],
  attribute_formatters: %{class: CanonicalTailwind},
  canonical_tailwind: [profile: :app],
  # ...
]
```

--------------------------------

### Add CanonicalTailwind to Dependencies

Source: https://github.com/aptinio/canonical_tailwind/blob/main/README.md

Include CanonicalTailwind in your project's development and test dependencies in `mix.exs`.

```elixir
defp deps do
  [
    {:canonical_tailwind, "~> 0.1.0", only: [:dev, :test], runtime: false}
  ]
end
```
