# blade-formatter

An opinionated blade template formatter for Laravel that respects readability

## Configuring blade-formatter

To configure project wide settings, put `.bladeformatterrc.json` or `.bladeformatterrc` in your repository root, blade-formatter will treat them as settings files.

e.g.

```json
{
  "indentSize": 4,
  "wrapAttributes": "auto",
  "wrapLineLength": 120,
  "endWithNewLine": true,
  "endOfLine": "LF",
  "useTabs": false,
  "sortTailwindcssClasses": true,
  "sortHtmlAttributes": "none",
  "noMultipleEmptyLines": false,
  "noPhpSyntaxCheck": false
}
```

blade-formatter will search up the directory structure until it reaches the root directory.

## Ignore Files

To ignore a specific file, put a `.bladeignore' in the root of your repository and the blade formatter will treat it as an ignored file.

e.g.

```gitignore
resources/views/users/index.blade.php
resources/views/products/*
resources/views/books/**/*
```

## Disabling format in file

To disable formatting in your file, you can use blade comments in the following format:

```blade
{{-- blade-formatter-disable --}}
    {{ $foo }}
    {{ $bar }}
{{-- blade-formatter-enable --}}
```

To disable formatiing on a specific line, you can use comment in the following format:

```blade
{{-- blade-formatter-disable-next-line --}}
    {{ $foo }}
```

To disable formatting for an entire file, put a `{{-- blade-formatter-disable --}}` comment at the beginning of the file:

```blade
{{-- blade-formatter-disable --}}

{{ $foo }}
```

## API

You can also use the blade formatter via API.

```js
const { BladeFormatter } = require('blade-formatter');

const input = `
<html>
  <body>
    <p>foo</p>
  </body>
</html>
`;

const options = {
  indentSize: 4,
  wrapAttributes: "auto",
  wrapLineLength: 120,
  endWithNewLine: true,
  useTabs: false,
  sortTailwindcssClasses: true,
};

new BladeFormatter(options).format(input).then((formatted) => {
  console.log(formatted);
});
```

### ESModule

```js
import BladeFormatter from "blade-formatter";
const { Formatter } = BladeFormatter;

const input = `
<html>
  <body>
    <p>foo</p>
  </body>
</html>
`;

const options = {
    indentSize: 2,
};

new Formatter(options).formatContent(input).then((formatted) => {
    console.log(formatted);
});
```

## Troubleshoot

- If you encounter the following error during installation

```
$ npm install -g blade-formatter
~~
current user ("nobody") does not have permission to access the dev dir
~~
```

Try setting the global user as root

```
$ npm -g config set user root
```

## TODO

- [x] custom directives
- [x] `@for` directive support
- [x] ignore formatting in blade comment
- [x] automatically add new line after directive

## Development

```bash
$ yarn install
$ yarn run watch # watch changes
```

You can use local docker image for development.
It might help if the host OS is not an amd64 architecture.

```bash
$ make build
$ make run example.php
```


## Testing

```bash
$ yarn install
$ yarn run test
```

You can use local docker image for testing.
It might help if the host OS is not an amd64 architecture.

```bash
$ make build
$ make test
$ make debug # attach
```
