def breakAfterFirst(substr: { substr = Regex }, s: String): (String, String)
SourceFind the first instance of Regex substr in string s, return a pair of the
prefix of string s up to and including sub and the rest of string s after sub.
def breakBeforeLast(substr: { substr = Regex }, s: String): (String, String)
SourceFind the last instance of substr in string s, return a pair of the
initial string including substr and suffix from substr.
def breakOnFirst(substr: { substr = Regex }, s: String): (String, String)
SourceFind the first instance of Regex substr in string s, return a pair of the
prefix of string s up to sub and the rest of string s including sub.
def breakOnLast(substr: { substr = Regex }, s: String): (String, String)
SourceFind the last instance of substr in string s, return a pair of the
initial string including substr and suffix from substr.
def countSubmatches(substr: { substr = Regex }, s: String): Int32
SourceCount the occurrences of substr in string s.
def countSubmatchesWithBounds(substr: { substr = Regex }, start: { start = Int32 }, end: { end = Int32 }, s: String): Int32
SourceCount the occurrences of substr in string s within the bounds (start, end).
Returns 0 if the bounds are invalid.
def endsWith(suffix: { suffix = Regex }, s: String): Bool
SourceReturns true if the string input ends the regular expression Regex suffix.
This will be slower than startsWith because there is no primitive Java function
to call, instead the matches of patt are iterated until the last one is found.
def flags(rgx: Regex): Set[Flag]
SourceReturn the flags used to build the Regex rgx.
def getFirst(substr: { substr = Regex }, s: String): Option[String]

If the Regex substr is not present in s return None.

SourceReturn the content of the first occurence of substr in s from the left within
the bounds (start, end).
If the Regex substr is not present in s or the bounds are invalid return None.
def getFirstWithOffset(substr: { substr = Regex }, offset: { offset = Int32 }, s: String): Option[String]
SourceThis is getFirst with a start offset.
If the Regex substr is not present in s return None.
def getLast(substr: { substr = Regex }, s: String): Option[String]
SourceReturn the content of the last occurence of substr in s from the left.
If the Regex substr is not present in s return None.
def getLastWithBounds(substr: { substr = Regex }, start: { start = Int32 }, end: { end = Int32 }, s: String): Option[String]
SourceReturn the content of the last occurence of substr in s from the left within
the bounds (start, end).
If the Regex substr is not present in s or the bounds are invalid return None.
def getLastWithOffset(substr: { substr = Regex }, offset: { offset = Int32 }, s: String): Option[String]
SourceThis is getLast with a start offset.
If the Regex substr is not present in s return None.
def getPrefix(substr: { substr = Regex }, s: String): Option[String]
SourceReturns Some(prefix) of string s if its prefix matches substr.
def getSuffix(substr: { substr = Regex }, s: String): Option[String]
SourceReturns Some(suffix) of string s if its suffix matches substr.
def indexOfFirst(substr: { substr = Regex }, s: String): Option[Int32]
SourceReturn the index of the first occurence of substr in s from the left.
If the Regex substr is not present in s return None.
def indexOfFirstWithBounds(substr: { substr = Regex }, start: { start = Int32 }, end: { end = Int32 }, s: String): Option[Int32]
SourceReturn the index of the first occurence of substr in s from the left within
the bounds (start, end).
If the Regex substr is not present in s or the bounds are invalid return None.
def indexOfFirstWithOffset(substr: { substr = Regex }, offset: { offset = Int32 }, s: String): Option[Int32]
SourceThis is indexOfFirst with a start offset.
If the Regex substr is not present in s return None.
def indexOfLast(substr: { substr = Regex }, s: String): Option[Int32]
SourceReturn the index of the last occurence of substr in s starting from the left.
If the Regex substr is not present in s return None.
def indexOfLastWithBounds(substr: { substr = Regex }, start: { start = Int32 }, end: { end = Int32 }, s: String): Option[Int32]
SourceReturn the index of the last occurence of substr in s from the left within
the bounds (start, end).
If the Regex substr is not present in s or the bounds are invalid return None.
def indexOfLastWithOffset(substr: { substr = Regex }, offset: { offset = Int32 }, s: String): Option[Int32]
SourceThis is indexOfLast with a start offset.
If the Regex substr is not present in s return None.
def indices(substr: { substr = Regex }, s: String): List[Int32]
SourceReturns the positions of the all the occurrences of substr in s.
If substr regexp matches the empty string, positions where an empty match
has been recognized will be returned.
def indicesWithBounds(substr: { substr = Regex }, start: { start = Int32 }, end: { end = Int32 }, s: String): List[Int32]
SourceReturns the positions of the all the occurrences of substr in s
within the bounds (start, end).
If substr regexp matches the empty string, positions where an empty match
has been recognized will be returned.
Returns Nil if there are no matches or the bounds are invalid.
def isMatch(rgx: Regex, s: String): Bool
SourceReturns true if the entire string s is matched by the Regex rgx.
def isMatchWithBounds(rgx: Regex, start: { start = Int32 }, end: { end = Int32 }, s: String): Bool
SourceReturns true if the entire string s is matched by the Regex rgx.
Returns false if the entire string does not match or the bounds are invalid.
def isSubmatch(rgx: Regex, s: String): Bool
SourceReturns true if the string input is matched by the Regex rgx
at any position within the string s.
def isSubmatchWithBounds(rgx: Regex, start: { start = Int32 }, end: { end = Int32 }, s: String): Bool
SourceReturns true if the string input is matched by the Regex rgx
at any position within the string s that is within the bounds (start, end).
Returns false if there is no match or the bounds are invalid.

SourceReturns string s with the first match of the regular expression from replaced by the string to.
def split(regex: { regex = Regex }, s: String): List[String]
SourceSplits the string s around matches of the Regex regex.
def startsWith(prefix: { prefix = Regex }, s: String): Bool
