Applies padding to a space/container.

Takes a space with x, y, width, height and applies padding on all sides, returning the adjusted inner space.

Parameters

• space - Map with :x, :y, :width, :height keys
• padding - Map with :top, :right, :bottom, :left keys

Returns

Map with adjusted dimensions accounting for padding.

Examples

iex> space = %{x: 10, y: 10, width: 100, height: 50}
iex> padding = %{top: 5, right: 10, bottom: 5, left: 10}
iex> LayoutUtils.apply_padding(space, padding)
%{x: 20, y: 15, width: 80, height: 40}

Calculates available space after subtracting used space.

Parameters

• total - Total available space
• used - Already used space

Returns

Remaining available space (minimum 0).

@spec center_text(String.t(), non_neg_integer()) :: String.t()

Centers text within a given width by prepending spaces.

Clamps a value between minimum and maximum bounds.

Parameters

• value - Value to clamp
• min - Minimum allowed value
• max - Maximum allowed value

Returns

Clamped value within the specified bounds.

Parses padding value into a normalized map.

Supports various padding formats:

• Single number: applies to all sides
• Two numbers: vertical, horizontal
• Four numbers: top, right, bottom, left

Parameters

• padding - Number, tuple, or string representation

Returns

Map with :top, :right, :bottom, :left keys.

Examples

iex> LayoutUtils.parse_padding(10)
%{top: 10, right: 10, bottom: 10, left: 10}

iex> LayoutUtils.parse_padding({5, 10})
%{top: 5, right: 10, bottom: 5, left: 10}

iex> LayoutUtils.parse_padding({1, 2, 3, 4})
%{top: 1, right: 2, bottom: 3, left: 4}
