Re: Why I can't use escape character in a string ?

\27 is working, thanks :)

(I thought it was octal code ... but it wasn't).

Anyway, hexa notation not working for me.

Bye

Hello,

Can someone explain to me why I can't use escape character in a string ?

I'm trying to send control code to the terminal but ESC is never transmited.

I tried

    f:write('\033[?17;0;0c')

and

    f:write('\x1b[?17;0;0c')

but none worked :(

I finally found

    f:write(string.char(0x1b) .. '[?17;0;0c')

which is working but I don't get why I can't escape ... ESC ?

Thanks

Laurent

The first escape will encode an exclamation mark, ASCII code 33.
The second should work; although the code is to reset the terminal's state and normally not used with parameters.
You may have looked for "\27[17;0;0m".
