cd aleppo

Using npm:

$ npm install aleppo

Validation - IS

Boolean validation functions. IS-functions can deal with one argument or multiple arguments as it accepts the spread syntax.

$ npm i aleppo.is

isUn (...inputs)

Checks if undefined returns true, otherwise returns false.

Examples

const { isUn } = require('aleppo')

Function execution - DOO

Executes multiple arguments with multiple functions in one call. Returns the results in required form. It passes each argument to all functions, after it's done with the first argument, it moves to process the second argument, so on so forth.

$ npm i aleppo.doo

doo.iterator(...funcs, ...args)

Returns iterator object of results.

Example : doo.iterator

const { doo } = require('aleppo')
// suppose we have two functions
function  greetings (name) { return `hello ${name}` }
function  bye (name) { return `goodbye ${name}!` }

const result =  doo.iterator([greetings, bye], ['Jimmy', 'Catherine'])
// pass the first argument to the first function.
result.next() // { value: 'hello Jimmy', done: false }

// pass the first argument to the second function.
result.next() // { value: 'goodbye Jimmy!', done: false }

// done with first argument, pass the second one to the first function.
result.next() // { value: 'hello Catherine', done: false }

// pass the second argument to the first function.
result.next() // { value: 'goodbye Catherine!', done: false }

// done will be true when finishing
result.next() // { value: undefined, done: true }

doo.array(...funcs, ...args)

Returns array of results.

Example

// continue working with same functions above
const result =  doo.array([greetings, bye], ['Jimmy', 'Catherine'])
console.log(result);
// will print
[ 'hello Jimmy', 'goodbye Jimmy!', 'hello Catherine', 'goodbye Catherine!' ]

doo.object(...funcs, ...args)

Returns array of objects {func: 'Function name', result: 'result of the function'}

Example

// continue working with same functions above
const result =  doo.object([greetings, bye], ['Jimmy', 'Catherine'])
console.log(result);
// will print
[
  { func: 'greetings', result: 'hello Jimmy' },
  { func: 'bye', result: 'goodbye Jimmy!' },
  { func: 'greetings', result: 'hello Catherine' },
  { func: 'bye', result: 'goodbye Catherine!' }
]

Time and date

A set of functions to deal and manipulate with time and date.

Delay

Calculates delay time according to given option then returns it in milliseconds.

$ npm i aleppo.delay

const { delay } = require('aleppo')

Types of options formats are:

year/years/yrs/y/yy/yyy/yyyy: delay by years.
d/dd/day/days: delay by days.
h//hr/hrs/hour/hours : delay by hours.
w/week/weeks: delay by weeks.
mo/mos/month/months/mth/mths : delay by months.
m/min/mins/minute/minutes: delay by minutes.
s/sec/secs/second/seconds : delay by seconds.
ms/mili/milisec/milisecs/milisecond/miliseconds : delay by milliseconds.

Example

const { delay } = require('aleppo')

delay('1h') //  3600000.
setTimeout(()=>'hello from the other side', delay('10m') + Date.now());
// will print hello form the other side after ten minutes from now.

Date:

Deals with time and date, in readable form. It has nine major helper functions to compute time and date.

$ npm i aleppo.date

date.now(, options)

Returns current date or time format according to required option.

options is String. Here all valid options.
Default value is current local time.
Date format can use one of the following separators.
now throws an error when options is not String or valid.

Example

const { date } = require('aleppo')

// default is local time.
date.now() // 6/17/2017, 3:00:03 PM

date.now('ts')
// return current timestamp 1495989532977.

date.now('hr:day:mo:week') // 18:Sunday:5:21
/*
* hr --> current hour
* hr --> current day
* hr --> current month
* hr --> current week
* : --> separator
*/

date.now('year,day,week,month,second') // 2017:Sunday:21:May:52
// same as above but more complex request and different separator.

date.now('year') // 2017
date.now('yy') // 17
date.now('mon') // 6
date.now('mth') // Jun
date.now('month') // June
date.now('wk') // 23

date.later(Xoptions, ts|fullDate)

Returns later date or time according to required option. Later computes the difference of time accurately, taking into consideration year type and days count in each month.

Xoptions is String. Combined of number of times with valid options. X is 1 by default.
ts If you want to return value in timestamp, pass 'ts'.
fullDate If you want to return full date object, contains { yr, mo, dy, hr, min, sec}
Complex date format is not allowed.
later throws an error when options is missing, not String or invalid.

Example

const { date } = require('aleppo')

/*
* Today is  Sunday, June 18, 2017
*/

date.later('10days') // Wednesday
date.later('10d') // 3
date.later('10dd') // Wed

date.later('2wk') // 26
date.later('2wk', 'ts') // 1499015984347
date.later('2wk', 'fullDate') // { yr: 2017, mo: 7, dy: 2, hr: 19, min: 20, sec: 0 }

date.later('12mo') // 6
date.later('12mth') // Jun
date.later('12month') // June

date.ago(Xoptions, ts|fullDate)

Returns any required format for time or date happened ago from now. ago computes the difference of time accurately, taking into consideration year type and days count in each month.

Xoptions is String. Combined of number of times with valid options. X is 1 by default.
ts If you want to return value in timestamp, pass 'ts'.
fullDate If you want to return full date object, contains { yr, mo, dy, hr, min, sec}
Complex date format is not allowed.
ago throws an error when options is missing, not String or invalid.

Example

const { date } = require('aleppo')

/*
* let's try time here since we tried date above.
* Today, time is 7: 30 PM
*/

date.ago('hour') // 18
date.ago('hr24') // 18
date.ago('hr12') // 6: 30 pm
date.ago('2hr12') // 5:30 pm
date.ago('2hr12', 'ts') // 1497803572706

date.readTs(timestamp)

Returns readable timestamp object. Contains yr, mo, dy, hr, min, sec.

timestamp can be Number or String.
readTs throws an error when timestamp is missing or invalid.

Example

const { date } = require('aleppo')

date.readTs(1503247105430)
// returns
{ yr: 2017, mo: 5, dy: 23, hr: 19, min: 15, sec: 45 }

date.isLeap(, year)

Returns Boolean. True if the year is leap. False for otherwise.

Default value is current year.
isLeap throws an error when year is not valid number or valid value.

Example

const { date } = require('aleppo')

date.isLeap(2019) // false
date.isLeap(2000) // true

// default is the current year 2017.
date.isLeap() // false

date.isCommon(, year)

Returns Boolean. True if the year is common. False for otherwise.

Default value is current year.
isCommon throws an error when year is not valid number or valid value.

Example

const { date } = require('aleppo')

date.isCommon(2028) // false
date.isCommon(2018) // true

// default is the current year 2017.
date.isCommon() // true

date.yearType(, year)

Returns String of year type common or leap.

year is Number
Default value is current year.
yearType throws an error when year is not valid number or valid value.

Example

const { date } = require('aleppo')
const date = getters.date

date.yearType(2000) // leap

date.yearType(1999) // common

date.yearType(2028) // leap

// default is the current year 2017.
date.yearType() // common

date.daysCountInMonth(, monthNum)

Returns number of days in required month. Taking into consideration whether the year is common, or leap to return the right number of days for February.

monthNum and year are Numbers
Default value for monthNum is current month number, year is current year.
daysCountInMonth throws an error if:
- Month number is not correct.
- One of the input date is not valid number.

Example

const { date } = require('aleppo')

// February in common year
date.daysCountInMonth(2, 2018) // 28

// February in leap year
date.daysCountInMonth(2, 2016) // 29

// regular month number
date.daysCountInMonth(1, 2017) // 31

// default, returns the current month(June) days for the current year(2017).
date.daysCountInMonth() // 30

date.countBtw(type, [, from|timestamp] [, to|timestamp ])

date.countBtw(type)
date.countBtw(type, to)
date.countBtw(type, from, to, i)

Computes the difference between two dates and returns objects of results.

type is type of request, all/year/month/week/day. All relevant options are valid.
from String or Number.
- Default value is 1/1/currentYear.
- String for date format request should be "dd/mm/yyyy".
- Number will be explained according to request type.
- If your request type is year number will be converted to 1/1/year.
- month to 1/month/currentYear. day to day/1/currentYear.
to String or Number. Same as from with major difference. to converts number to current date instead of beginning of the year.
- Default value is currentDay/currentMonth/currentYear.
- If your request type is year number will be converted to: currentDay/currentMonth/year.
- months to currentDay/month/currentYear. day to day/currentMonth/currentYear.
i A flag constiable, false by default. If you want to include the last day in the result, pass 'i' to include it.
returns object of request type and remainder of calculations if there is any.
Note:
Both from and to accepts timestamp as numbers.
One date argument is considered as to.
Date format can use one of the following separators.
countBtw throws an error if:
- No type is provided.
- One of the input date is not valid.
- Type of request is not valid or missing.

Example
