Can't match string with leading dot

[vwkd]

(Thanks for reporting an issue to micromatch! If you haven't already read the contributor guidelines, Please do that now, then proceed to fill out the details below.)

It seems that a leading dot prevents a glob from matching. For example, ./my/*/file.js should match ./my/relative/file.js but it doesn't.

Please describe the minimum necessary steps to reproduce this issue:

import micromatch from "micromatch";

const glob = `./my/*/file.js`
const isMatch = micromatch.matcher(glob);
console.log(isMatch(./my/relative/file.js`);
// logs false

What is happening that shouldn't be?

Glob doesn't match string.

What should be happening instead?

Glob should match string. It works with minimatch and also globster.xyz.

Try passing a custom format function on the options, as follows:

const micromatch = require('micromatch');

const format = input => input.replace(/^\.\//, '');

console.log(micromatch.isMatch('./my/relative/file.js', 'my/*/file.js', { format })); //=> true
console.log(micromatch.isMatch('./my/relative/file.js', './my/*/file.js', { format })); //=> true
console.log(micromatch.isMatch('./my/relative/file.js', '**/my/*/file.js', { format })); //=> true

The issue of leading dot slashes has been discussed a few times on this and related repositories. Since ./ is contrived and is only really used in require() and import statements, it's not a pattern that is typically found in real file system paths. The most reliable way to handle such patterns is to use path.normalize() or otherwise ensure that your file paths are normalized before using any matcher. Or you can use micromatch's format option. We decided on this approach because it seemed to be the lesser of all other evils.

Please let me know if this helps.

Thanks for the reply. Feel free to close this if this indeed works as intended. Though it would be helpful to mention this in the README so other people won't have to run into debugging this issue.

const match = micromatch(['/a/file/path/.hiddenFile.ejs.txt', '*.ejs.*', {matchBase: true}]

This is awful DX
