abstract class BaseMillParser extends BaseNumberParser

Parser for a Mill. The input to this parser is a string of tokens, each separated by any amount of white space. The input is then converted to an IndexedSeq of Strings which is then reversed and rendered as a single String. The purpose of this strange little dance is to reverse the order of the tokens without reversing the tokens themselves.

class ExpressionParser extends JavaTokenParsers, String => Try[Expression]

ExpressionParser is a parsing utility designed for processing and interpreting arithmetic expressions. It extends JavaTokenParsers to leverage combinator-based parsing functionality.

ExpressionParser is a parsing utility designed for processing and interpreting arithmetic expressions. It extends JavaTokenParsers to leverage combinator-based parsing functionality.

CONSIDER I'm not sure that the Expression structure is that helpful in creating expressions such as BiFunction, etc. Probably we should put the operator first (or maybe last).

The parser supports parsing arithmetic expressions involving addition, subtraction, multiplication, and division, as well as handling nested expressions using parentheses. It is capable of transforming input strings into structured representations of expressions using a robust parsing approach. The class provides detailed breakdowns of expressions into components like terms, factors, numeric values, and additional constructs.

This class also supports error handling, ensuring any invalid input is captured and reported as a Failure within a Try.

Additionally, this class offers utility methods for combining and transforming parse results, and encapsulates complex parsing rules for modular expression parsing.

object NumberParser extends BaseNumberParser

Object for parsing numerical values, extending the functionality of the BaseNumberParser class. Provides methods for parsing, interpreting, and representing numbers, potentially with fuzziness, exponents, and other modifications.

Object for parsing numerical values, extending the functionality of the BaseNumberParser class. Provides methods for parsing, interpreting, and representing numbers, potentially with fuzziness, exponents, and other modifications.

This object specializes in defining the parsing rules for various numeric representations, including:

  • Simple numbers or rational numbers.
  • Numbers with fuzziness or uncertainty.
  • Factors representing constants, symbols, or mathematical concepts.

The parsing logic accounts for optional components such as fractional parts and exponents, and encapsulates results within domain-specific types, such as Number, NumberWithFuzziness, and ValuableNumber.
