display() function

display() returns the Flux literal representation of any value as a string.

Basic types are converted directly to a string. Bytes types are represented as a string of lowercase hexadecimal characters prefixed with 0x. Composite types (arrays, dictionaries, and records) are represented in a syntax similar to their equivalent Flux literal representation.

Note the following about the resulting string representation:

  • It cannot always be parsed back into the original value.
  • It may span multiple lines.
  • It may change between Flux versions.

display() differs from string() in that display() recursively converts values inside composite types to strings. string() does not operate on composite types.

Display a value as part of a table

Use array.from() and display() to quickly observe any value.

import "array"

    rows: [
            dict: display(v: ["a": 1, "b": 2]),
            record: display(v: {x: 1, y: 2}),
            array: display(v: [5, 6, 7]),

Display a record

x = {a: 1, b: 2, c: 3}

display(v: x)// Returns {a: 1, b: 2, c: 3}

Display an array

x = [1, 2, 3]

display(v: x)// Returns [1, 2, 3]

Display a dictionary

x = ["a": 1, "b": 2, "c": 3]

display(v: x)// Returns [a: 1, b: 2, c: 3]

Display bytes

x = bytes(v: "abc")

display(v: x)// Returns 0x616263

Display a composite value

x = {bytes: bytes(v: "abc"), string: "str", array: [1, 2, 3], dict: ["a": 1, "b": 2, "c": 3]}

display(v: x)// Returns
// {
//    array: [1, 2, 3],
//    bytes: 0x616263,
//    dict: [a: 1, b: 2, c: 3],
//    string: str
// }
