Crate textmode

textmode is a library for terminal interaction built on top of a real terminal parsing library. It allows you to do arbitrary drawing operations on an in-memory screen, and then update the visible terminal output to reflect the in-memory screen via an optimized diff algorithm when you are finished. Being built on a real terminal parsing library means that while normal curses-like operations are available:

use textmode::Textmode;
let mut tm = textmode::Output::new().await?;
tm.clear();
tm.move_to(5, 5);
tm.set_fgcolor(textmode::color::RED);
tm.write_str("foo");
tm.refresh().await?;

you can also write data containing arbitrary terminal escape codes to the output and they will also do the right thing:

tm.write(b"\x1b[34m\x1b[3;9Hbar\x1b[m");
tm.refresh().await?;

This module is split into two main parts: Output and Input. See the documentation for those types for more details. Additionally, the blocking module provides an equivalent interface with blocking calls instead of async.
