API

ansiAlign(text, [opts])

Align the given text per the line with the greatest string-width, returning a new string (or array).

Arguments

• text: required, string or array

  The text to align. If a string is given, it will be split using either the opts.split value or '\n' by default. If an array is given, a different array of modified strings will be returned.

• opts: optional, object

  Options to change behavior, see below.

Options

• opts.align: string, default 'center'

  The alignment mode. Use 'center' for center-alignment, 'right' for right-alignment, or 'left' for left-alignment. Note that the given text is assumed to be left-aligned already, so specifying align: 'left' just returns the text as is (no-op).

• opts.split: string or RegExp, default '\n'

  The separator to use when splitting the text. Only used if text is given as a string.

• opts.pad: string, default ' '

  The value used to left-pad (prepend to) lines of lesser width. Will be repeated as necessary to adjust alignment to the line with the greatest width.

ansiAlign.center(text)

ansiAlign.right(text)

Alias for ansiAlign(text, { align: 'right' }).

ansiAlign.left(text)

Alias for ansiAlign(text, { align: 'left' }), which is a no-op.
