Ignore patterns starting with ! causes 0 results

[Jason3S]

See: https://codesandbox.io/p/devbox/xr7rqj

import { glob } from "tinyglobby";
import fg from "fast-glob";

async function run() {
  console.log("Run");

  const ignore = ["node_modules", "docs/build/**", "!docs/build/README.md"];

  const resultFG = await fg.glob("**", { ignore });
  const resultTiny = await glob("**", { ignore });

  console.log("%o", { resultFG, resultTiny });
}

run();

Results:

{
  resultFG: [
    'README.md',
    'index.js',
    'package-lock.json',
    'package.json',
    'yarn.lock',
    'docs/README.md',
    'docs/docs-file.txt',
    [length]: 7
  ],
  resultTiny: [ [length]: 0 ]
}

Expected:
Results to be similar to fast-glob.
Note: fast-glob incorrectly removes docs/build/README.md

i see, will fix. thank you

i couldn't make it properly work, but it should be consistent with fast-glob now, making this issue solved. can you try it by using the following preview build in your package.json?

  "tinyglobby": "https://pkg.pr.new/tinyglobby@b43ffdf",

Thank you very much.

😢 Ignoring negated patterns is not great. I believe globby supports these. Because this package is named tinyglobby folks might be coming from globby and this difference should definitely be documented.

It means that if any ignore pattern has a ! then the entire ignore option must be set to an empty [] and processed afterwards with something like the ignore package.

[SuperchupuDev]

can you show a case where globby produces different results? i thought it didn't support it

Thanks for the quick reply @SuperchupuDev! In digging into this. I looked at the sandbox provided by @Jason3S which does contain a globby compare and it too misses it. I believe the code base I'm on does in fact do the workaround with the ignore() package 🙃. No documentation needed then 🙈
