Consola

Introducción

The console is used to display text output from a VEX V5 C++ project.

• In VEXcode V5, console output appears in the Monitor window.

• In VS Code, console output appears in the Terminal.

When a new project begins running, the cursor starts at row 1 of the console.

Functions

The following functions can be used to print text in the console:

• printf – Print text to the console.

printf

Prints text on the screen using the current cursor position.

Available Functions

void printf(const char *value);

Parameters

Parameter	Type	Description
value	const char*	The string (in quotations) or integers to print to the console.

Return Values

Notes

• Text will not be sent to the console until a new line is started.

// Print a message to the console
printf("Hello, robot!");
// Print a new line to the console
printf("\n");

Control Sequences

The console supports ANSI control sequences for formatting and screen control.

• Clear console — Clears all text from the console.

• Change the Font Color — Changes the text color.

Clear console

By printing \033[2J, everything inside the console will be cleared.

Examples

// Print to the console, then clear it after
// 2 seconds
printf("VEXcode");
wait(2, seconds);
printf("\033[2J\n");

Change the Font Color

You can change what color the font will be when printing to the console by using the following sequences:

• \033[30m — Black

• \033[31m — Red

• \033[32m — Green

• \033[33m — Yellow

• \033[34m — Blue

• \033[35m — Purple

• \033[36m — Cyan

• \033[37m — White

• \033[91m — Orange

• \033[97m — Transparent

Notes

• All color codes need to follow an escape sequence \033 in order to function.

Examples

// Print VEXcode in Red to the console
printf("\033[31mVEXcode");

// Set the console text color to Red before printing
printf("\033[31m");
printf("VEXcode");
