map(ArrayToApply, functionToApply)

ArrayToApply

Type: String

# returns: [3, 12, 27]

reject(List, functionToApply)

# returns: 'Intelisis'

documents().updateSection(JSON) (process only)

JSON

Type: JSON

Updates one or more columns in an array type section, with an equal number of values.

This function is asynchronous, so it needs to be called with the exec/into functions.

options = {
    step: 'general.Task 2',
    section : 'section1',
    columns : ['input2'],
    values:['valor raul']
}

exec g4.documents().updateSection options, into err, result
return callback err, result
# returns: 1 or Error

catalogs().publishAndAffect(JSON) (process only)

JSON

Type: Object

Publish a new catalog item, both in NoSQL and in Kernel

This function is asynchronous, so it needs to be called with the exec/into functions.

options = {
    step: 'general.Alta Personal',
    catalogName : 'Personal',
    api: 'catalogs',
    protocol: 'http'
}

exec g4.catalogs().publishAndAffect options, into err, result
return callback err, result

This functions requires an outgoing (al Kernel) mapping:

Currency

priceNet(options)

options

Type: Object

Calculates a net price, passing an object with the following keys:

• Discount Number for discount in line (percent or direct cost)
• DiscountInPercent Boolean which indicates if the line discount is in Number or % format
• GlobalDiscount Number for 2nd discount
• Tax1 Number for tax (e.g. IVA)
• Tax2 Number for tax 2 (e.g. IEPS)

Example:

options = {
    Price: @Precio
    WithTaxes: g4.contains(Extra.ConImpuestos, 'si')
    Discount: @Descuento
    DiscountInPercent: g4.contains(Extra.DescuentoEnPorcentaje, 'si')
    GlobalDiscount: Extra.DescuentoGlobal
    Tax1: @IVA
    Tax2: @IEPS
}

result g4.priceNet(options)

Depends on:

• contains

dailyWage(wage)

wage

Type: Number

Calculates daily wage.

• wage indicates quantity of wage per month to calculate

Example:

# Example in coffee
wage = 3000
dailyWage = g4.dailyWage wage

console.log dailyWage # 100

Date

dateAdd(datePart, number, date)

datePart

Type: String

number

Type: Number

date

Type: Number

Modify the original date by adding time.

• datePart time measurement
• number indicates number to adding
• date indicates date to modify in format iso date eg: 2016-01-01T12:00:00.000Z

Example:

# Example in coffee
date = '2016-01-01T12:00:00.000Z'
number    = 4
datePart  = 'h'

date = g4.dateAdd datePart, number, date
console.log date # 2016-01-01T16:00:00.000Z

There are all the time measurements to use:

If you want to add multiple different keys at the same time, you can pass them in as an object literal.

# Example in coffee
date = '2016-01-01T12:00:00.000Z'

date = g4.dateAdd { days:1, hours: 4 }, date
console.log date # 2016-01-02T16:00:00.000Z

dateDiff(datePart, endDate, startDate)

datePart

Type: String

endDate

Type: String

startDate

Type: String

Gets the difference between two dates.

• datePart time measurement
• endDate indicates first date to compare
• startDate indicates second date to compare

Example:

# Example in coffee
datePart  = 'y'
startDate = '1991-02-24T03:45:56.334Z'
endDate   = '2016-03-08T18:45:56.334Z'

difference = g4.dateDiff datePart, endDate, startDate
console.log difference # 25
