extensions option doesn't work for multiple extension.

[hata6502]

What version of textlint are you using?

v11.3.1

What file type (Markdown, plain text, etc.) are you using?
Laravel Blade (.blade.php)

What did you do? Please include the actual source code causing the issue.
I tried to check Laravel Blade as html.
So I set .textlintrc.json to the following.

{
  "filters": {
    "comments": true
  },
  "plugins": {
    "html": {
      "extensions": [
        ".blade.php"
      ]
    }
  },
  "rules": {
    "preset-japanese": true,
    "preset-jtf-style": {
      "3.1.1.全角文字と半角文字の間": false
    },
    "prh": {
      "rulePaths": [
        "node_modules/prh/prh-rules/media/WEB+DB_PRESS.yml"
      ]
    }
  }
}

But textlint doesn't detect .blade.php files as html.

What did you expect to happen?
I think textlint doesn't support multiple extension (i.e. .blade.php, .tar.gz, etc).
When .textlintrc.json was set to the following,

    "html": {
      "extensions": [
        ".php"
      ]
    }

textlint detected .blade.php as html correctly.

What actually happened? Please include the actual, raw output from textlint.

Here is debug log.

I have no idea for multiple extensions.
We need to research that other program like ESLint, Editor(VSCode, Atom) support it.

📝 Note: textlint just use path.extname(path) and it return .php from file.foo.php.

[MartinBonner]

I think the solution is likely to be the equivalent of the following python

    for suffix in suffix_list:
        if path.endswith(suffix)
            return True
    return False

rather than the current

    return path.extname(path) in suffix_list

(Apologies for the python code, but I can only read js rather than writing it, and I think the idea is clear.)

[azu]

I think that endswith approach is reasonable.

textlint/packages/@textlint/kernel/src/descriptor/TextlintPluginDescriptors.ts

Lines 42 to 46 in d4c5075

	findPluginDescriptorWithExt(ext: string) {
	return this.descriptors.find((descriptor) => {
	return descriptor.availableExtensions.includes(ext);
	});
	}

→

 findPluginDescriptorWithExt(ext: string) { 
     return this.descriptors.find((descriptor) => { 
         // availableExtensions are defined by each plugins
         // ext is current process file extension
         // e.g. 
         // If availableExtensions: [".php"]
         // ext: ".php" → match
         // ext: ".blade.php" → match
         // ext: ".php.txt" →  does not match
         return descriptor.availableExtensions.some(availableExtension => ext.endsWith(availableExtension)); 
     }); 
 }
