Does not match for negative ignore

[zaverden]

I have following structure:

data
├── section
│   └── file1.json
└── section_2
    └── file2.json

When I run

glob.sync('**', { ignore: ['!data/section/**'] }

I expect to get [ 'data/section/file1.json' ] but got an empty array.

In a real-world scenario (for similar files structure) I receive a set of project-root globs, but I need to get files from specific section only (without modifying globs). That's why I need for negative pattern in ignore

Pattern negation isn't supported, in the main pattern or in the ignore option. Why not just glob for the thing you're un-negating?

Why not just glob for the thing you're un-negating?

Here's a concrete examples of why glob negation is helpful in the configuration of cSpell: I want to spell-check my english localization strings, but not localized strings in any other language:

    "src/locales/**",
    "!src/locales/en.yaml",

@justingrant Ok, so use an ignore option, and a pattern.

glob('src/locales/**', { ignore: 'src/locales/en.yaml' })

The challenge (at least in this use case) is when the list is already negated, like in a .gitignore file or (like in this case) a JSON config file that can't call glob directly. Here's the ugly hack I ended up with. Not sure if there's a better way to do it.

  "ignorePaths": [
    "src/locales/[^e]*.*",
    "src/locales/es.yaml",
  ],
