fn pub static new -> Stderr {
  Stderr(sys.stderr)
}

fn pub static new -> Stderr

Returns a new Stderr.

fn pub mut flush -> Result[Nil, Never] {
  Result.Ok(nil)
}

fn pub mut flush -> Result[Nil, Never]

Flushes any pending writes.

Since this type doesn't use any buffering, this method is a no-op.

fn pub mut print(string: String) -> Result[Nil, Error] {
  write_string(string).then(fn (_) { write_string('\n') })
}

fn pub mut print(string: String) -> Result[Nil, Error]

Writes the entirety of string to the underlying stream, followed by writing a Unix newline to the stream.

fn pub terminal? -> Bool {
  sys.terminal?(@fd)
}

fn pub terminal? -> Bool

Returns true if the output stream is connected to a terminal/TTY.

Examples

import std.stdio (Stderr)

Stderr.new.terminal? # => true

fn pub mut write_bytes(bytes: ref ByteArray) -> Result[Nil, Error] {
  write_all_internal(bytes.to_pointer, bytes.size)
}

fn pub mut write_bytes(bytes: ref ByteArray) -> Result[Nil, Error]

Writes the entirety of bytes to the underlying stream.

Types implementing this method must guarantee that upon returning from this method, either all of the data is written and a Ok(Nil) is returned, or an Error(Error) is returned.

fn pub mut write_string(string: String) -> Result[Nil, Error] {
  write_all_internal(string.to_pointer, string.size)
}

fn pub mut write_string(string: String) -> Result[Nil, Error]

Writes the entirety of string to the underlying stream.

See Write.write_bytes for more details.
