bool-expr-generator

Installation

NPM

npm install --save bool-expr-generator

Usage

import BoolExpr from 'bool-expr-generator';
const boolGenerator = new BoolExpr();
const expr = boolGenerator.generate(); // 'true && false'
// You may pass an option object to the constructor
const boolGenerator = new BoolExpr({
	complexity: 3,
	operators: ["||", "&&", "^"],
	operatorsDisplayed: {"^": "XOR", "&&": "AND", "||": "OR"},
	logicalValues: [true, false, 0, 1],
	invertedValue: true,
});
const expr = boolGenerator.generate(); // 'false XOR 1 OR true'
// If cou customised the operatorsDisplayed option you can use the convert method to convert the expression into an evaluable one
console.log(boolGenerator.convert(expr)); // 'false ^ 1 || true'
// Update options:
boolGenerator.options({complexity: 4});
console.log(boolGenerator.generate()); // true XOR 1 AND !0 OR !0
// You can also use a nested expression with or without its own options
const boolGenerator = new BoolExpr({
	logicalValues: [true, false, BoolExpr.nestedExpr({complexity: 2, logicalValues: [0, 1]})], // Note that it is advised to specify the logicalValues
});
const expr = boolGenerator.generate(); // 'false && (0 || 1)'
