|
* \brief Line editing support with history
|
|
*
|
|
* This file implements a kernel for line editing through a terminal, with history of the typed lines.
|
|
* Basic feature of this module:
|
|
*
|
|
* \li Abstracted from I/O. The user must provide hooks for getc and putc functions.
|
|
* \li Basic support for ANSI escape sequences for input of special codes.
|
|
* \li Support for command name completion (through a hook).
