fields

Function

  fields — return the flattened path names of a record

Synopsis

fields(r: record) -> [[string]]

Description

The fields function returns an array of string arrays of all the field names in record r. A field’s path name is representing by an array of strings since the dot separator is an unreliable indicator of field boundaries as . itself can appear in a field name.

error("missing") is returned if r is not a record.

Examples

Extract the fields of a nested record:

yield fields(this)

{a:1,b:2,c:{d:3,e:4}}

Easily convert to dotted names if you prefer:

over fields(this) |> yield join(this,".")

{a:1,b:2,c:{d:3,e:4}}

A record is expected:

yield {f:fields(this)}

true
