JS Beautify hack to works with blade directives (laravel)

beautify-html.js

function style_html(html_source, options, js_beautify, css_beautify) {
  html_source = html_source.replace(/\@([^\n\s]*)/ig, "<blade $1/>");
 
  ...
  
  sweet_code = sweet_code.replace(/<blade ([^\n]*)\/>/ig, "@$1");
  sweet_code = sweet_code.replace(/\(\ \'/ig, "('");
  
  ...

  return sweet_code;

}

Does not work with @if-statements or @foreach.

// Before
@section('content')
    @if($page == 1)
        {!! $page !!}
    @endif
@endsection

// After
@section('content')
@if($page == 1) {!! $page !!}
@endif
@endsection

ugh this is very frustrating.. several blade extensions in vscode but not one properly handles formatting inside blade files.. and this solution here while great and thanks for sharing is much too complicated

here's to hoping someone takes this solution and makes it into an easy-to-install extension

I made some improvement from codes above, this is not perfect but makes blade formatter cleaner

function Beautifier(html_source, options, js_beautify, css_beautify) {
    //Wrapper function to invoke all the necessary constructors and deal with the output.
    html_source = html_source || '';
    
    // BEGIN
    html_source = html_source.replace(/\{\{((?:(?!\}\}).)+)\}\}/g, function (m, c) {
        if (c) {
            c = c.replace(/(^[ \t]*|[ \t]*$)/g, '');
            c = c.replace(/'/g, ''');
            c = c.replace(/"/g, '"');
            c = encodeURIComponent(c);
        }
        return "{{" + c + "}}";
    });
    html_source = html_source.replace(/^[ \t]*@([a-z]+)([^\n]*)$/gim, function (m, d, c) {
        if (c) {
            c = c.replace(/'/g, ''');
            c = c.replace(/"/g, '"');
            c = "|" + encodeURIComponent(c);
        }
        switch (d) {
            case 'break':
            case 'continue':
            case 'empty':
            case 'else':
            case 'elseif':
            case 'extends':
            case 'case':
            case 'csrf':
            case 'include':
            case 'json':
            case 'method':
            case 'parent':
            case 'stack':
            case 'yield':
                return "<blade " + d + c + "/>";
                break;
            default:
                if (d.startsWith('end')) {
                    return "</blade " + d + c + ">";
                } else {
                    return "<blade " + d + c + ">";
                }
                break;
        }
    });
    // END

    ...

    var sweet_code = multi_parser.output.join('').replace(/[\r\n\t ]+$/, '');
                    
    // BEGIN
    sweet_code = sweet_code.replace(/^([ \t]*)<\/?blade ([a-z]+)\|?([^>\/]+)?\/?>$/gim, function (m, s, d, c) {
        if (c) {
            c = decodeURIComponent(c);
            c = c.replace(/&#39;/g, "'");
            c = c.replace(/&#34;/g, '"');
            c = c.replace(/^[ \t]*/g, '');
        } else {
            c = "";
        }
        if (!s) {
            s = "";
        }
        return s + "@" + d + c;
    });
    sweet_code = sweet_code.replace(/\{\{((?:(?!\}\}).)+)\}\}/g, function (m, c) {
        if (c) {
            c = decodeURIComponent(c);
            c = c.replace(/&#39;/g, "'");
            c = c.replace(/&#34;/g, '"');
            c = c.replace(/(^[ \t]*|[ \t]*$)/g, ' ');
        }
        return "{{" + c + "}}";
    });
    // END

    ...

    return sweet_code;
}

hope this will help

happy coding!

@fzldn, thanks for the snippet, works great. This part of the regex [^\n] needs to be changed to [^\r\n] to remove CR 0x0D character on Windows.

I added some other minor changes and created this gist based on your code.

I also make the gist for js-beautify hack for HookyQR.beautify version 1.4.2 here the gist
