When a dead key is composing, we gave no information about what was
composing. Contrast with Windows and macOS where we show the first
key in the composition as part of that state.
This commit makes an attempt to populate equivalent information.
It's a bit more complex with the xkeyboard stuff as there can be
multiple combining sequences and there's no guarantee that we can
show a meaningful label.
We try our best for the common case of a single dead key, and have
a probably reasonable fall back for other cases where we don't
other get that information.
This allows removing DeadKeyStatus::Holding.
They have their own versions of these options, and logically it doesn't
make sense to use the default_prog from the `local` domain with a wsl
domain.
refs: #1242
This returns the default set of domains that would be populated
in the wsl_domains config. This is useful if you want to override
eg: the default_prog for specific domain(s), or want to otherwise
add additional variations on the default list.
When set, changes the default domain to the domain with the specified
name, which potentially affects the default program.
eg: default_domain = "WSL:Ubuntu-18.04" will cause the initial tab
to be spawned via WSL.
The idea is that we want to be able to spawn into wsl with the
convenience of a local domain, but without the awkwardness of
it having a different filesystem namespace.
It would also be great to be able to spawn a new tab or pane
in the same domain and pick up the cwd of the existing one.
The WslDomain allows the user to explicitly list WslDomains
and control eg: default shell, username and so on, but wezterm
will pre-fill a default list of domains based on the `wsl -l`
output that we were already using in the launcher menu.
The existing LocalDomain has been augmented to understand that
it may need to fixup a command invocation and that gives it
the opportunity to rewrite the command so that we can launch
it via `wsl.exe` and pass down the cwd and so on.
This same technique might be extensible to eg: docker instances
in the future.
This commit:
* Introduces `wsl_domains` config and its default list of wsl
distributions
* Creates LocalDomain instances from that list
* The launcher menu allows spawning a new tab via one of those domains
lalt-` is technically a dead key combo, so we entered dead key
processing, then realized that
`send_composed_key_when_left_alt_is_pressed == false` and that
we should ignore the dead-key-ness of the combo, but returned
a composed result, which had the modifiers discarded.
The correct way to handle this is to signal that it wasn't
dead after all and to allow the main flow to build the KeyEvent
as normal.
The client machinery would try to spawn an async attempt at
detaching the unixdomain from the mux on shutdown, but since
we're in the middle of tearing down the scoped executor,
we could sometimes panic.
The client we have in this situation isn't actually associated
with a domain, so we don't need to detach in that situation.
Formalize that by making it an Option, and address the
fanout.
Using the new publish/discovery stuff from the past couple of commits,
if we can find a matching socket path for a running gui, and the
configuration is likely a match, then use the mux protocol to talk
to the already running gui and ask it to spawn the equivalent program
into the same process.

We need 100% of the info for it to work correctly, so this commit:
* Exposes the keyboard encoding mode via the Pane trait
* Adds the scan code to the RawKeyEvent
* Has the GUI perform the encoding if the keyboard is set that way
* Removes the basic encoder from termwiz in favor of the gui level one
The net result is that we bypass the Pane::key_up/Pane::key_down methods
in almost all cases when the encoding mode is set to win32-input-mode.
There is now a config option: allow_win32_input_mode that can be
used to prevent using this mode.
refs: #1509
When spawned with no WEZTERM_UNIX_SOCKET environment set,
we now prefer to resolve the gui instance, falling back to
the mux if it doesn't look like the gui is running.
`wezterm cli --prefer-mux` will use the original behavior of
trying to resolve the path from the unix domain in the config.
This commit causes the terminal to emit win32-input-mode encoded key up
and down events for a limited subset of keys When win32-input-mode is
enabled.
We limit them to keys where we know the VK key code equivalent,
and where those keys are either not representable (eg: modifier
only key events), or may generate ambiguous output (eg: CTRL-SPACE
in different keyboard layouts).
However, in my experiments, modifier only key presses confuse powershell
and cause it to emit `@`, so I've disabled that in the code for now.

Nothing generates them right now, and the mux client has no
way to represent them on the wire.
I'm considering constraining them to just win32 for now.
refs: https://github.com/wez/wezterm/issues/1509
This is a baby step that formalizes the different encoding schemes into
an enum, and hooks up the decset sequence for win32-input-mode.
It doesn't change any of the actual encoding at this time.

It was showing the whole text for the cluster for each shaped
glyph.
Fix it up to map back to the corresponding cell range and
extract the text from the line.
Include the x_advance metric in the output while we're in
there.
