This class implements a glob pattern matcher similar to the one found in bash, but with some key differences.

Namely, that * matches all characters and does not exclude path separators.

• ? matches a single character.
• * matches zero or more characters.
• [] matches one character in the bracket. Character ranges, e.g., [a-z], and negative sets via [^ab] or [!ab] are also supported.
• {,...} matches one of the globs in the list. Nested brace expansions are not supported. If MaxSubPatterns is empty then brace expansions are not supported and characters {,} are treated as literals.
• \ escapes the next character so it is treated as a literal.

Some known edge cases are:

• The literal ] is allowed as the first character in a character class, i.e., []] is valid and matches the literal ].
• The empty character class, i.e., [], is invalid.
• Empty or singleton brace expansions, e.g., {}, {a}, are invalid.
• The literals } and , that are not inside a brace expansion are taken as literals, e.g., ,} is valid but { is not.

Examples:

• *[/\\]foo.{c,cpp} will match (unix or windows) paths to files named foo.c or foo.cpp.
• _Z{N,NK,}S[tabsoid]* will match mangled C++ standard library functions.
