The cli.hpp header provides a convenience include / wrapper around daniele77/cli <https://github.com/daniele77/cli>_. It also exposes cli's include folder, so including "cli.hpp" is completely equivalent to including <cli/cli.h> - but you can additionally include other files from <cli/>. It also provides a few conveniences:

1. a espp::Cli class which inherits from cli::CliSession and has a near-identical implementation as cli's CliFileSesson, with the exception that it explicitly reads character by character instead of line by line and prints out the characters as they are being input, and
2. a static espp::Cli::configure_stdin_stdout() function which sets up the esp UART to enable blocking std::cin read, which is needed for std::cin to work (and therefore - currently - for cli to work). This function is automatically called by the espp::Cli constructor, but it can also be called manually without needing to create a espp::Cli object if you wish to simply use the std::cin and related functions.
3. a espp::LineInput class which provides support for an interactive input system which can optionally have history with navigation. It allows for getting the user input as an arbitrary input string while enabling some keyboard movement and editing commands. The espp::Cli uses the espp::LineInput class internally to handle the input aspects of the Cli, but the espp::LineInput class can be re-used anywhere you want to get one or more lines of user input in a reusable way. Note that if you use it in another class / outside the espp::Cli class, you will need to call the espp::Cli::configure_stdin_stdout() as mentioned above.

The Cli and associated LineInput classes support:

• ctrl+a (move to beginning of line)
• ctrl+e (move to end of line)
• ctrl+n (move up a line / previous input history)
• ctrl+p (move down a line / next input history)
• ctrl+k (delete from the cursor to the end of the line)
• ctrl+b (move the cursor back one character)
• ctrl+f (move the cursor forward one character)
• ctrl+l (clear the screen)

Please see the documentation for the cli submodule <https://github.com/daniele77/cli>_ if you have any questions about usage beyond the examples provided here.

The example shows how to use the Cli component to setup and run a command line interface (CLI) on the ESP.
