function::ansi_cursor_move - Linux

Overview

function::ansi_cursor_move is a specialized tool used for precise cursor positioning within a terminal window. It enables the control of the cursor’s horizontal and vertical coordinates, allowing for dynamic and interactive text-based user interfaces.

Syntax

function::ansi_cursor_move(x, y)

Parameters

• x: The horizontal coordinate (column) to move the cursor to.
• y: The vertical coordinate (row) to move the cursor to.

Options/Flags

This command has no configuration options or flags.

Examples

Move the Cursor to a Specific Position

To move the cursor to the center of the screen, use:

function::ansi_cursor_move(10, 10)

Increment the Cursor Position

To move the cursor down by 2 rows and right by 3 columns, use:

function::ansi_cursor_move(x + 3, y + 2)

Common Issues

• Out-of-Bounds Positioning: Attempting to move the cursor outside the terminal window’s boundaries will result in undefined behavior.
• Invalid Coordinates: Specifying non-numeric values for x or y may cause errors.

• User Input: Used to obtain the cursor position from user input for navigation or editing.
• Formatting: Combined with ANSI escape sequences to render tables, charts, or other structured text.
