Overview

A cell representation for terminal display with character, color, background color, and styling attributes

The Cell class encapsulates the properties of a single character cell in a terminal display, including its visual characteristics such as the displayed character, text color, background color, and styling attributes. It provides methods to compare cells and convert them to their string representation with ANSI escape codes for terminal rendering.

Instance Method Details

#==(other) ⇒ Boolean

The == method compares two Cell objects for equality by their internal array representation

This method checks if the current Cell instance is equal to another Cell instance by comparing their underlying array representations returned by to_a

Parameters:

Returns:

  • (Boolean) —

    true if both cells have identical char, color, on_color, and styles values, false otherwise

def ==(other)
  to_a == other.to_a
end

#to_s ⇒ String

The to_s method converts a Cell object into its string representation with ANSI styling

This method constructs a formatted string that includes the cell’s character along with its color, background color, and text style attributes using ANSI escape sequences. The resulting string is suitable for display in terminal environments that support ANSI colors.

Returns:

  • (String) —

    a formatted string containing the cell’s visual representation with appropriate ANSI styling codes for terminal rendering
