operator

Documentation

Overview

Package operator implements logical, arithmetic, bitwise and comparison operators as functions (like the Python operator module). Includes unary, binary, and n-ary functions with overflow checked variants.

This is the frozen version of the package previously at `tawesoft.co.uk/go/operator`. See migration instructions.

The package in this directory is released to the public domain (5 July 2022) or, alternatively, is available under the LICENSE.txt at the root of the golib project.

Example

// This example demonstrates using operators in lookup tables for a
// command-line calculator program.
package main

import (
	"bufio"
	"fmt"
	"os"
	"strconv"
	"strings"

	"github.com/tawesoft/golib/v2/legacy/operator"
)

var operations = map[string]checkedOperation{
	"+": operator.Float64Checked.Binary.Add,
	"-": operator.Float64Checked.Binary.Sub,
	"*": operator.Float64Checked.Binary.Mul,
	"/": operator.Float64Checked.Binary.Div,
}

func getNumber(prompt string) float64 {
	for {
		fmt.Print(prompt)
		var text, _ = reader.ReadString('\n')
		var result, err = strconv.ParseFloat(strings.TrimSpace(text), 64)
		if err != nil {
			fmt.Printf("Sorry, try again. (%v)\n", err)
			continue
		}
		return result
	}
}

func getOperation(prompt string) checkedOperation {
	for {
		fmt.Print(prompt)
		var text, _ = reader.ReadString('\n')
		var operator, ok = operations[strings.TrimSpace(text)]
		if !ok {
			fmt.Println("Sorry, try again.")
			continue
		}
		return operator
	}
}

func main() {
	var firstNumber = getNumber("Enter a number (then press enter): ")
	var operation = getOperation("Enter +, -, * or / (then press enter) for add, subtract, multiply, or divide: ")
	var secondNumber = getNumber("Enter another number (then press enter): ")
	var result, err = operation(firstNumber, secondNumber)
