Std.Show

View source →

The Show protocol: convert values to their human-readable String form.

This is the counterpart of Elixir's String.Chars / Inspect split: show/1 produces a representation suitable for debugging and log output. Strings are wrapped in quotes, atoms are prefixed with :; callers that want raw text should use Std.String.from_* instead.

Examples

use Std.Show

show(42)                                # => "42"
show("hi")                              # => "\"hi\""
show(:ok)                               # => ":ok"
show_line(true)                         # => "true\n"

Protocols

  • proto Show(T)

    Convert a value of any Show-able type to its string representation.

Functions

  • # fn __group__() -> Atom

    Group tag consumed by Cure.Stdlib.Preload.

  • # fn show(x: Int) -> String

    Render an integer as decimal digits.

  • # fn show(x: Float) -> String

    Render a float as a decimal string.

  • # fn show(x: String) -> String

    Render a string with surrounding quotes; does not escape.

  • # fn show(x: Bool) -> String

    Render a boolean as the literal words true or false.

  • # fn show(x: Atom) -> String

    Render an atom as ":" <> name.

  • # fn show_line(x: T) -> String

    Same as show/1 but append a trailing newline. Useful for logging.
