Raxol.Terminal.ScreenBuffer.Core (Raxol Terminal v2.8.0)

Core functionality for screen buffer creation, initialization, and basic queries. Consolidates: Initializer, Common, Helpers, and basic state management.

Summary

Types

t()

Functions

clear(buffer)

Clears the entire buffer.

get_cell(buffer, x, y)

Gets a cell at the specified coordinates.

get_char(buffer, x, y)

Gets the character at the specified coordinates.

get_dimensions(map)

Gets the buffer dimensions.

get_height(map)

Gets the buffer height.

get_line(buffer, y)

Gets a line of cells.

get_width(map)

Gets the buffer width.

new(width, height, scrollback_limit \\ 1000)

Creates a new screen buffer with the specified dimensions, clamped to the terminal size ceiling (Raxol.Core.Utils.Validation.clamp_terminal_size/2).

resize(buffer, new_width, new_height)

Resizes the buffer to new dimensions, clamped to the terminal size ceiling.

to_cell_grid(buffer)

Converts buffer to legacy cell grid format for backward compatibility.

within_bounds?(map, x, y)

Checks if coordinates are within buffer bounds.
