TrickB PkgGoDev

TrickB is a simple golang library that allows users to set an extra unset state for Boolean alike types.

Implementation

TrickB implements the standard logical operators supported by boolean types.

  • And
  • Or
  • Nand
  • Not
  • Nor
  • Xor

It supports 3 states on a variable False, True and UnSet. UnSet denotes that a bool like variable has been initiated but not set. Please keep in mind that the default state for TrickB custom type is UnSet to set it, you need to do a TrickB.True/False of the variable.

Utilities

As of now as support for two utility functions.

  • Out Gives out the string representation of the Boolean state(including unset).
  • IsSet Just provides a boolean indicator to if the specific flag is set or unset. Note that this does not tell user if flag is set to True/False.
  • TrickBFromString This one takes a string and returns a trickBoolean equivalent type(True, False, Unset). This can be coupled with Out or other logic gates.

Usage

To get package locally

go get github.com/mainak90/trickB

Import in code

import "github.com/mainak90/trickB"

Examples

examples/...

Live example

a := tb.UnSet
b := tb.False
out := a.And(b).Out()
fmt.Println(out)

Chain different strings as boolean equivalent types against logic gates and get result

fmt.Println(tb.TrickBFromString("true").And(tb.TrickBFromString("unset")).Out())
