export

The export keyword exposes an element, introduced inside a module, outside the module. This keyword operates with the keyword import as its counterpart.

export scalar value

A scalar value can be exported:

// Module named '/sample/my-module'
export const myHello = "Hello"

Then, it can be imported:

import "/sample/my-module" as M with
  myHello
 
show scalar "" with myHello

export user-defined function

A user-defined function can be exported:

// Module named '/sample/my-module'
export def pure plusOne(x: number) with
  return x + 1

Then, it can be imported:

import "/sample/my-module" as M with
  plusOne
 
show scalar "" with plusOne(2) // 3

export inline enums

An enum can be exported:

// Module named 'sample/my-module'
export table enum E = "A", "B"

Then, it can be imported:

import "/sample/my-module" as M with
  E
 
a = enum<<E>>("A")
show scalar "" with text(a)

export table comprehension

A table comprehension can be exported:

// Module named '/sample/my-module'
export table T = with
  [| as A, as B  |]
  [| 1,    true  |]
  [| 2,    false |]
  [| 4,    true  |]

Then, it can be imported:

import "/sample/my-module" as M with
  T
 
show table "" a1b3 with T.A, T.B

export path schema

A path schema can be exported:

// Module named '/sample/my-module'
export schema '/sample/products.csv' with
  Product : text
  Color : text
  Price : number

When a module is imported, all the path schemas that it exports are automatically imported as well.

import "/sample/my-module" as M

read '/sample/products.csv' as Products

show table "My Products" a1b3 with
  Products.Product
  Products.Color
  Products.Price

export named schema

A named schema can be exported:

// Module named '/sample/my-module'
export schema Products with
  Product : text
  Color : text
  Price : number

Then, it can be imported:

import "/sample/my-module" as M
 
read "/sample/products.csv" as Products with
  schema M.Products
 
show table "My Products" a1b3 with
  Products.Product
  Products.Color
  Products.Price
