Wez Furlong 1ab438c1e2 improve emoji width calculation
I noticed while scrolling `emoji-test.txt` that some of the combined
emoji sequences rendered very poorly.  This was due to the unicode
width being reported as up to 4 in some cases.

Digging into it, I discovered that the unicode width crate uses a
standard calculation that doesn't take emoji combination sequences
into account (see https://github.com/unicode-rs/unicode-width/issues/4).

This commit takes a dep on the xi-unicode crate as a lightweight way
to gain access to emoji tables and test whether a given grapheme is
part of a combining sequence of emoji.

Terminal Wizardry

This is a rust crate that provides a number of support functions for applications interested in either displaying data to a terminal or in building a terminal emulator.

It is currently in active development and subject to fairly wild sweeping changes.

Included functionality:

  • Surface models a terminal display and its component Cells
  • Terminal attributes are aware of modern features such as True Color, Hyperlinks and will also support sixel and iterm style terminal graphics display.
  • Surfaces include a log of Changes and an API for consuming and applying deltas. This is a powerful building block for synchronizing screen instances.
  • Escape sequence parser decodes inscrutable escape sequences and gives them semantic meaning, making the code that uses them clearer. The decoded escapes can be re-encoded, allowing applications to start with the semantic meaning and emit the appropriate escape sequence without embedding obscure binary bytes.
  • Capabilities allows probing for terminal capabilities that may not be included in the system terminfo database, and overriding them in an embedding application.
  • Terminal trait provides an abstraction over unix style ttys and Windows style console APIs. Changes from Surface can be rendered to Terminals. Terminals allow decoding mouse and keyboard inputs in both blocking or non-blocking mode.
  • Widget trait allows composition of UI elements at a higher level.
  • LineEditor implements shell-like line editing functionality.

Windows

Testing via Wine:

sudo apt install gcc-mingw-w64-x86-64
rustup target add x86_64-pc-windows-gnu
cargo build --target=x86_64-pc-windows-gnu  --example hello

Then, from an X session of some kind:

wineconsole cmd.exe

and from there you can launch the generated .exe files; they are found under target/x86_64-pc-windows-gnu/debug
