fmt

The fmt library contains helper functions for formatting strings.

//fmt.pretty(v <: value) <: string

Returns a pretty (i.e. with newlines and indents) string representation of the given value.

Usage:

$ arrai eval "//fmt.pretty({'a': (b: [1,2])})"{  'a': (    b: [1, 2],  ),}

info

The rendering of output strings differs between arrai eval and the interactive shell. As such, the result of //fmt.pretty in the interactive shell will not appear very pretty:

@> //fmt.pretty({'a': (b: [1,2])})"{\n  'a': (\n    b: [1, 2],\n  ),\n}"
