Glob Patterns

A glob pattern is a string used for pattern matching against the names in a filesystem directory such that a name is expanded into a list of names matching that pattern.

The following rules are used by Orbit for any string interpreted as a glob-style pattern:

• ? matches any single character.
• * matches any (possibly empty) sequence of characters.
• ** matches the current directory and arbitrary subdirectories. To match files in arbitrary subdiretories, use **/*.
  This sequence must form a single path component, so both **a and b** are invalid and will result in an error. A sequence of more than two consecutive * characters is also invalid.
• [...] matches any character inside the brackets. Character sequences can also specify ranges of characters, as ordered by Unicode, so e.g. [0-9] specifies any character between 0 and 9 inclusive. An unclosed bracket is invalid.
• [!...] is the negation of [...], i.e. it matches any characters not in the brackets.
• The metacharacters ?, *, [, ] can be matched by using brackets (e.g. [?]). When a ] occurs immediately following [ or [! then it is interpreted as being part of, rather then ending, the character set, so ] and NOT ] can be matched by []] and [!]] respectively. The - character can be specified inside a character sequence pattern by placing it at the start or the end, e.g. [abc-].
• Path-component separator characters (/) must be matched by a literal /, rather than by * or ? or [...].
• Patterns are case-sensitive (only considering upper/lower case relationships between ASCII characters).
• Paths that contain components that start with a . will not require that . appears literally in the pattern; *, ?, **, or [...] will match.

These rules originate from the glob crate.
