This commit refines bidi property handling: * experimental_bidi has been split into two new configuration settings; `bidi_enabled` (which controls whether the terminal performs implicit bidi processing) and `bidi_direction` which specifies the base direction and whether auto detection is enabled. * The `Line` type can now store those bidi properties (they are actually split across 3 bits representing enabled, auto-detection and direction) * The terminal now has a concept of active bidi properties and default bidi properties * The default properties are pulled from the wezterm configuration * active bidi properties are potentially set via escape sequences, BDSM (which sets bidi_enabled) and SCP (which sets bidi_direction). We don't support the 2501 temporary dec private mode suggested by the BIDI recommendation doc at this time. * When creating new `Line`'s or clearing from the start of a `Line`, the effective bidi properties are computed (from the active props, falling back to default propr) and applied to the `Line`. * When rendering the line, we now look at its bidi properties instead of just the global config. The default bidi properties are `bidi_enabled: false` and `bidi_direction: LeftToRight` which corresponds to the typical bidi-unaware mode of most terminals. It is possible to live reload the config to change the effective defaults, but note that they apply, by design, to new lines being processed through the terminal. That means existing output is left unaffected by a config reload, but subsequently printed lines will respect it. Pressing CTRL-L or otherwise contriving to have the running application refresh its display should cause the refreshed display to update and apply the new bidi mode. refs: #784 |

wezterm-term
This crate provides the core of the virtual terminal emulator implementation used by wezterm. The home for this crate is in the wezterm repo and development is tracked at https://github.com/wez/wezterm/.
It is full featured, providing terminal escape sequence parsing, keyboard and mouse input encoding, a model for the screen cells including scrollback, sixel and iTerm2 image support, OSC 8 Hyperlinks and a wide range of terminal cell attributes.
This crate does not provide any kind of gui, nor does it directly
manage a PTY; you provide a std::io::Write implementation that
could connect to a PTY, and supply bytes to the model via the
advance_bytes method.
The entrypoint to the crate is the Terminal struct.
