const static Regex defVal

Default value is Regex("").

virtual override Bool equals(Obj? obj)

Equality is based on pattern string and flags.

Str flags()

Return flags string

static new fromStr(Str pattern, Str flags := "")

Compile a regular expression pattern string. Flags is a string of ASCII chars. In JavaScript the flags are passed directly to RegExp. In Java the flags are matched against known constants or ignored. The following cross-platform flags are supported:

• i: case insensitive
• m: multi-line support for start/end matching
• s: dot all to allow "." to match newlines

static Regex glob(Str pattern)

Make a Regex which will match a glob pattern:

• "?": match one unknown char (maps to "." in regex)
• "*": match zero or more unknown char (maps to ".*" in regex)
• any other character is matched exactly

virtual override Int hash()

Return toStr.hash.

RegexMatcher matcher(Str s)

Return a RegexMatcher instance to use for matching operations against the specified string.

Bool matches(Str s)

Convenience for matcher(s).matches.

static Regex quote(Str str)

Make a Regex that matches the given string exactly. All non-alpha numeric characters are escaped.

Str[] split(Str s, Int limit := 0)

Split the specified string around matches of this pattern. The limit parameter specifies how many times to apply the pattern:

• If limit is greater than zero, the pattern is applied at most limit-1 times and any remaining input will be returned as the list's last item.
• If limit is less than zero, then the pattern is matched as many times as possible.
• If limit is zero, then the pattern is matched as many times as possible, but trailing empty strings are discarded.

virtual override Str toStr()

Return the regular expression pattern string.
