@knighttower/js-power-helper-functions v1.0.4

Note:

For better maintenance, this library has been placed along with JsUtilities (https://github.com/knighttower/JsUtility) to create an easier entry point for many resources that will collaborate together --> only the docs will remain here for now.

Installation

npm i @knighttower/js-utility-functions

yarn add @knighttower/js-utility-functions

getDirectivesFromString

Note: All the above with the exception of the Id/class will be converted into actual objects

Function Signature

function getDirectivesFromString(settings: String|Array|Object): Object|void|null;

Converts strings formats into objects.

• Function: getDirectivesFromString(settings)
• Parameters: {String|Array|Object} settings
• Returns: {Object|void|null}

Handles the following patterns to get an object from string attributes:

• Matches the JSON objects as string: {'directive':{key:value}} OR {key:value}
• Matches the Array as string: value, value OR 'value','value'
• Matches a multi-array string like [value,value],value]
• Matches object-style strings: directive.tablet(...values) OR directiveexpression
• Matches string ID or class: literals Id(#) or class (.). Note that in Vue it needs to be in quotes attr="'#theId'"
• Matches simple directive function style: directive(#idOr.Class)

Examples

getDirectivesFromString('directive.tablet(...values)'); // {directive: {tablet: 'values'}}
getDirectivesFromString('[[value,value]],value]'); // {directive: 'values', directive2: 'values'}
getDirectivesFromString('directive.tablet|mobile(...values)'); // {directive: {tablet: 'values', mobile: 'values'}}
getDirectivesFromString('directive.tablet(...values)'); // {directive: {tablet: 'values'}}

findAndReplaceInArray

Function Signature

function findAndReplaceInArray(arr: Array, find: String, value: Array|Object|String): Null|Array;

Recursively will loop in array to find the desired target.

• Function: findAndReplaceInArray(arr, find, value)
• Parameters: {Array} arr, {String} find, {Array|Object|String} value
• Returns: {Null|Array}

Examples

/**
 * Recursively will loop in array to find the desired target
 * @function findAndReplaceInArray
 * @param {Array} arr
 * @param {String} find The target (needle)
 * @param {Array|Object|String} value Replacer
 * @return {Null|Array}
 * @example findAndReplaceInArray([1,2,3,4,5], 3, 'three') // [1,2,'three',4,5]
 */

getMatchInBetween

Function Signature

function getMatchInBetween(str: String, p1: String|Regex, p2: String|Regex, all: Boolean): String|Array|Null;

Find a match in between two delimeters, either string or regex given, returns clean matches.

• Function: getMatchInBetween(str, p1, p2, all)
• Parameters: {String} str, {String|Regex} p1, {String|Regex} p2, {Boolean} all
• Returns: {String|Array|Null}

Examples

/**
 * find a match in between two delimeters, either string or regex given, returns clean matches
 * @function getMatchBlock
 * @param {String} str
 * @param {String|Regex} p1
 * @param {String|Regex} p2
 * @param {Boolean} all If it should return all matches or single one (default)
 * @return {String|Array|Null}
 * @example getMatchInBetween('hello world', 'h', 'd') // 'ello worl'
 * @example getMatchInBetween('hello <world/>', '<', '/>', true) // ['world']
 * @example getMatchInBetween('hello <world/>', '<', '/>') // 'world'
 */

getMatchBlock

getMatchBlock(str, p1, p2, all = false)

/**
 * Find math by delimeters returns raw matches
 * @function getMatchBlock
 * @param {String} str
 * @param {String|Regex} p1
 * @param {String|Regex} p2
 * @param {Boolean} all If it should return all matches or single one (default)
 * @return {String|Array|Void}
 * @example getMatchBlock('is a hello world today', 'h', 'd') // 'hello world'
 * @example getMatchBlock('is a hello world today', 'h', 'd', true) // ['hello world']
 * @example getMatchBlock('is a <hello world/> today', '<', '/>') // '<hello world/>'
 */

cleanStr

Clean a string from delimeters or just trimmed if no delimeters given

Function Signature

function cleanStr(str: String, p1: String|Regex, p2: String|Regex): String;

Examples

/**
 * Clean a string from delimeters or just trimmed if no delimeters given
 * @funtion cleanStr
 * @param {String} str - String to use
 * @param {String|Regex} p1 - Delimeter 1
 * @param {String|Regex} p2 - Delimeter 2
 * @return {String}
 * @example cleanStr('hello world', 'h', 'd') // 'ello worl'
 * @example cleanStr('  hello world  ') // 'hello world'
 * @example cleanStr('hello world', 'hello') // 'world'
 * @example cleanStr('Hello World. Sunshine is here!', '\..*!') // Hello World
 * @example cleanStr('Hello World. Sunshine is here!', /Hello/g) // ' World. Sunshine is here!'
 * @example cleanStr('Hello World. Sunshine is here!', /Hello/g, /Sunshine/g) // ' World.  is here!'
 */

setExpString

Scapes a string to create a regex or returns the regex if it already is an expression

setExpString(exp)

/**
 * Scapes a string to create a regex or returns the regex if it already is an expression
 * @function setExpString
 * @param {String|Regex} exp
 * @return {String|Regex}
 * @example setExpString('hello') // '\h\e\l\l\o'
 * @example setExpString(/hello/) // /hello/
 * @example setExpString([hello]) // \\[hello\\/ then use like new new RegExp(setExpString(StringOrRegex))
 */

setLookUpExp

Regex builder to get a match in between two delimeters

setLookUpExp(p1, p2)

/**
 * Regex builder to get a match in between two delimeters
 * @function setLookUpExp
 * @param {String|Regex} p1 - Delimeter 1
 * @param {String|Regex} p2 - Delimeter 2
 * @return {String} - Regex
 * @example setLookUpExp('h', 'd') // 'h((.|\n)*?)d'
 * @usage:
 * const pattern = setLookUpExp(".", "!");
const regex = new RegExp(pattern, 'g');
const text = "Hello World. Sunshine is here! Have fun!";
const matches = text.match(regex);
console.log(matches);  // Output: [". Sunshine is here!"]
 */

removeQuotes

Function Signature

function removeQuotes(str: String): String;
