Method to create a named Matcher, based on the given function f of form T => MatchResult[R]. Unusually, this method's identifier has a capital first letter. This is done to mimic the Parser method in the parser-combinators. It has the advantage of looking somewhat like a constructor of a Matcher.

TODO: rename Matcher as UnnamedMatcher and this as Matcher.

If f is a partial function, it may result in a MatchError. In such a case, this is simply treated as a Miss. However, if f throws some other non-fatal exception, then that will result in an Error.

def valve[Q, T](p: (Q, T) => Boolean): Matcher[(Q, T), T]

Matcher whose success depends on the application of a function f to the input, then the application of a predicate to a control value and the result of f.

lazy val decimalNumber: Parser[String]

A parser that matches a decimal number. The parser matches numbers with optional leading digits, a decimal point, and optional trailing digits.

A parser that matches a decimal number. The parser matches numbers with optional leading digits, a decimal point, and optional trailing digits.

Examples of matched patterns include:

  • Whole numbers: "123"
  • Floating-point numbers with leading digits: "123.456"
  • Floating-point numbers without leading digits: ".456"
  • Floating-point numbers with trailing decimal point: "123."

lazy val floatingPointNumber: Parser[String]

A parser for matching floating-point numbers in string format. This parser identifies numbers with optional signs, decimal points, optional scientific notation (e/E with an optional sign), and optional floating-point type suffixes (f/F/d/D).

A parser for matching floating-point numbers in string format. This parser identifies numbers with optional signs, decimal points, optional scientific notation (e/E with an optional sign), and optional floating-point type suffixes (f/F/d/D).

The recognized pattern includes:

  • Optional leading negative sign (-).
  • Digits before and/or after a decimal point.
  • Scientific notation with an optional positive or negative sign.
  • Optional floating-point suffix (f, F, d, D).

The parsing is performed using a provided regular expression pattern.
