Module rurtle::readline [−] [src]

Core readline functionality

This module is just a wrapper for a small FFI interface to the C readline library.

This module is tailored to the needs of the Rurtle CLI and not intended as a general readline-rust wrapper.

Windows support

Note that readline is not available on Windows. readline will still work with less awesomeness though, and add_history is just a stub.

This module will automatically select the right readline version for the target os.

add_history	Add the given line to the readline history so the user can navigate back to it.
readline	Display the given prompt and return the input line. If readline encounters an EOF, `None` is returned.
