Add Support for Directory Name Validation

[884js]

Hello,

I really like this library!

I have a feature request:

Could you make it possible to include directory names as part of the validation process?

In Next.js’s App Router, directory names directly correspond to the routing paths. In such cases, I’d like to prevent developers from using directory names that don’t comply with specific rules.

For example:
• app/review_guideline/page.tsx → Invalid
• app/review-guideline/page.tsx → Valid

Would it be possible to add this functionality?

Thank you!

@Uki884 Hi! I'm really excited about the feature request 👀

Creating rules that include folder names is a great idea!

I'll take some time to think about the specifications. If you're interested, feel free to submit a PR 👍

memo: My Idea.

Add to validate-filename/directory-naming-rules.

{
  "rules": {
    "validate-filename/directory-naming-rules": [
      "error",
      {
        rules: [
          {
            case: 'pascal', 
            target: "app",
            excludes: ['_components'], 
          }
        ] 
      }
    ],
}

or add to existing rules

{
  "rules": {
    "validate-filename/naming-rules": [
      "error",
      {
        rules: [
          {
            case: 'pascal', // camel or pascal or snake or kebab or flat
            target: "**/components/**", // target "components" folder
            excludes: ['hooks'], // "hooks" folder is excluded.
          }
          {
            case: 'camel',
            target: "**/hooks/**", // target "hooks" folder
            patterns: '^use', // file names begin with "use".
          },
          {
            case: 'camel',
            target: "app", // target "app" folder,
            isTargetDirectory: true, // Target to a directory,
            excludes: ['_components'], 
          }. 
        ] 
      }
    ],
}

Yeah! Will be nice to have a way to match specific folder. In my case i have and app folder at the root and the another app folder inside the src (this is because I'm using FSD architecture in Nextjs) I have set this rule but it matches both app folder and I want only to match the one from the root

"validate-filename/naming-rules": [
      "error",
      {
        "rules": [
          {
            "case": "kebab", 
            "target": "**/app/**",
            "excludes": ["src", "app"],
            "patterns": "^(page|layout|loading|error|not-found|route|template).ts$"
          }
       ]
     }
]
