fix(path): Remove non node symbols (#18630)

/** Convert a glob string to a regular expression.
|
||||
*
|
||||
* Tries to match bash glob expansion as closely as possible.
|
||||
*
|
||||
* Basic glob syntax:
|
||||
* - `*` - Matches everything without leaving the path segment.
|
||||
* - `?` - Matches any single character.
|
||||
* - `{foo,bar}` - Matches `foo` or `bar`.
|
||||
* - `[abcd]` - Matches `a`, `b`, `c` or `d`.
|
||||
* - `[a-d]` - Matches `a`, `b`, `c` or `d`.
|
||||
* - `[!abcd]` - Matches any single character besides `a`, `b`, `c` or `d`.
|
||||
* - `[[:<class>:]]` - Matches any character belonging to `<class>`.
|
||||
* - `[[:alnum:]]` - Matches any digit or letter.
|
||||
* - `[[:digit:]abc]` - Matches any digit, `a`, `b` or `c`.
|
||||
* - See https://facelessuser.github.io/wcmatch/glob/#posix-character-classes
|
||||
* for a complete list of supported character classes.
|
||||
* - `\` - Escapes the next character for an `os` other than `"windows"`.
|
||||
* - \` - Escapes the next character for `os` set to `"windows"`.
|
||||
* - `/` - Path separator.
|
||||
* - `\` - Additional path separator only for `os` set to `"windows"`.
|
||||
*
|
||||
* Extended syntax:
|
||||
* - Requires `{ extended: true }`.
|
||||
* - `?(foo|bar)` - Matches 0 or 1 instance of `{foo,bar}`.
|
||||
* - `@(foo|bar)` - Matches 1 instance of `{foo,bar}`. They behave the same.
|
||||
* - `*(foo|bar)` - Matches _n_ instances of `{foo,bar}`.
|
||||
* - `+(foo|bar)` - Matches _n > 0_ instances of `{foo,bar}`.
|
||||
* - `!(foo|bar)` - Matches anything other than `{foo,bar}`.
|
||||
* - See https://www.linuxjournal.com/content/bash-extended-globbing.
|
||||
*
|
||||
* Globstar syntax:
|
||||
* - Requires `{ globstar: true }`.
|
||||
* - `**` - Matches any number of any path segments.
|
||||
* - Must comprise its entire path segment in the provided glob.
|
||||
* - See https://www.linuxjournal.com/content/globstar-new-bash-globbing-option.
|
||||
*
|
||||
* Note the following properties:
|
||||
* - The generated `RegExp` is anchored at both start and end.
|
||||
* - Repeating and trailing separators are tolerated. Trailing separators in the
|
||||
* provided glob have no meaning and are discarded.
|
||||
* - Absolute globs will only match absolute paths, etc.
|
||||
* - Empty globs will match nothing.
|
||||
* - Any special glob syntax must be contained to one path segment. For example,
|
||||
* `?(foo|bar/baz)` is invalid. The separator will take precedence and the
|
||||
* first segment ends with an unclosed group.
|
||||
* - If a path segment ends with unclosed groups or a dangling escape prefix, a
|
||||
* parse error has occurred. Every character for that segment is taken
|
||||
* literally in this event.
|
||||
*
|
||||
* Limitations:
|
||||
* - A negative group like `!(foo|bar)` will wrongly be converted to a negative
|
||||
* look-ahead followed by a wildcard. This means that `!(foo).js` will wrongly
|
||||
* fail to match `foobar.js`, even though `foobar` is not `foo`. Effectively,
|
||||
* `!(foo|bar)` is treated like `!(@(foo|bar)*)`. This will work correctly if
|
||||
* the group occurs not nested at the end of the segment. */
