Wez Furlong 121c090f22 wezterm: implement leader key binding support
This commit introduces a new `leader` configuration setting
that acts as a modal modifier key.

If leader is specified then pressing that key combination
will enable a virtual LEADER modifier.

While LEADER is active, only defined key assignments that include
LEADER in the `mods` mask will be recognized.  Other keypresses
will be swallowed and NOT passed through to the terminal.

LEADER stays active until a keypress is registered (whether it
matches a key binding or not), or until it has been active for
the duration specified by `timeout_milliseconds`, at which point
it will automatically cancel itself.

Here's an example configuration using LEADER:

```lua
local wezterm = require 'wezterm';

return {
  -- timeout_milliseconds defaults to 1000 and can be omitted
  leader = { key="a", mods="CTRL", timeout_milliseconds=1000 },
  keys = {
    {key="|", mods="LEADER|SHIFT", action=wezterm.action{SplitHorizontal={domain="CurrentPaneDomain"}}},
    -- Send "CTRL-A" to the terminal when pressing CTRL-A, CTRL-A
    {key="a", mods="LEADER|CTRL", action=wezterm.action{SendString="\x01"}},
  }
}
```

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 Support

Termwiz understands how to work with both the legacy console APIs and the new PTY and virtual terminal features available in Windows 10, allowing for true color terminal applications on Windows 10.
