/**
|
|
* This file is a small equivalent to the GNU readline library, but it
|
|
* was originally designed for small systems, like Atmel AVR
|
|
* microcontrollers (8 bits). Indeed, we don't use any malloc that is
|
|
* sometimes not implemented (or just not recommended) on such
|
|
* systems.
|
|
*
|
|
* Obviously, it does not support as many things as the GNU readline,
|
|
* but at least it supports some interesting features like a kill
|
|
* buffer and a command history.
|
|
*
|
|
* It also have a feature that does not have the GNU readline (as far
|
|
* as I know): we can have several instances of it running at the same
|
|
* time, even on a monothread program, since it works with callbacks.
|
|
*
|
|
* The lib is designed for a client-side or a server-side use:
|
|
* - server-side: the server receives all data from a socket, including
|
|
* control chars, like arrows, tabulations, ... The client is
|
|
* very simple, it can be a telnet or a minicom through a serial line.
|
|
* - client-side: the client receives its data through its stdin for
|
|
* instance.
