ByteReplaceWriter returns an io.Writer that wraps w, where all occurrences of the old byte are replaced with the new string on Write calls.

FlushRuneChunk is a helper that repeatedly calls d.FlushRune until EOF, calling fn for every rune that is decoded.

NewUTF8WrapWriter returns a new WrapWriter filter that implements io.Writer, and decodes and encodes runes in UTF-8.

NewWrapWriter returns a new WrapWriter with the given target width in runes, producing output on the underlying writer w.

PrefixLineWriter returns a WriteFlusher that wraps w.

PrefixWriter returns an io.Writer that wraps w, where the prefix is written out immediately before the first non-empty Write call.

TerminalSize returns the dimensions of the terminal, if it's available from the OS, otherwise returns an error.
