Using npm:
$ npm install aleppo
Boolean validation functions. IS-functions can deal with one argument or multiple arguments as it accepts the spread syntax.
$ npm i aleppo.is
Checks if undefined returns true, otherwise returns false.
Examples
const { isUn } = require('aleppo')
isUn(undefined, a, b, c, d, e) // true

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
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 }
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!' ]
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'])

[
{ func: 'greetings', result: 'hello Jimmy' },
{ func: 'bye', result: 'goodbye Jimmy!' },
{ func: 'greetings', result: 'hello Catherine' },
{ func: 'bye', result: 'goodbye Catherine!' }
]
A set of functions to deal and manipulate with time and date.
Calculates delay time according to given option then returns it in milliseconds.
$ npm i aleppo.delay
const { delay } = require('aleppo')

: 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.
Deals with time and date, in readable form. It has nine major helper functions to compute time and date.
$ npm i aleppo.date
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
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
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')

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 }
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(2000) // true
// default is the current year 2017.
date.isLeap() // false
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

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
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
andyear
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

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 asfrom
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
andto
accepts timestamp as numbers. - One date argument is considered as
to
. - Date format can use one of the following separators.
countBtw
