export type Settingsint     barfloat   pricestring  phrase...

Example of library function to print out label.

export printLabel(Settings setup) =>if setup.variablevar label lab = nalabel.delete(lab)lab := label.new(setup.bar, setup.price, setup.phrase, color = setup.bg)elselabel.new(setup.bar, setup.price, setup.phrase, color = setup.bg)

Usage of types

Settings setup = Settings.new(bar_index[0], priceInput, phraseInput, colorInput, variableInput)

Alternative way to write types

Settings setup = Settings.new(   bar      = bar_index[0],   price    = priceInput,   phrase   = phraseInput,   variable = variableInput)

Usage of types into custom function / library function.
