1956054e6f Move default key assignments to gui layer, add more metadata
Create a list of command definitions to hold the default key
assignments.

That list has more metadata, such as a brief and longer human
readable description of the purpose, and allows for (in the
future) reasoning about the context where the command is valid,
as well as providing more information when rendering in the

b908e2dd8c mux: fix update issue
The heart of the issue here was due to the window-reuse logic that
tries to reuse a GUI window that is no longer associated with a mux
window.

Each GUI window subscribes to the mux for mux events, but it filters
according to is understanding of the mux_window_id that it is associated
with.

The GUI frontend maintains an mapping of GUI and mux window so that it
knows when to reuse a GUI window and when to close it.

When connecting to a remote mux, wezterm spawns a temporary connection
progress window.  Once connected, workspace reconiliation is triggered
and decides that this window can be used for something else.

As part of workspace reconciliation, this mapping can be adjusted and
the frontend will notify a GUI window that its mux window has changed.

However, that updated mux window was not visible to the mux notification
subscription so the effect was that a variety of notifications were
effectively ignored, including updates from a remote mux when the output
was changed.

To make matters worse, the workspace reconciliation could "double-tap"
window creation and create excess windows only to later realize they
weren't needed and close them out again.

This commit addresses both of these concerns.

d8cfdae27b avoid ping-ponging focus updates with multiple windows
The bug here was that each paint call in a window would update
the focus state of its panes to reflect the one that had focus.

However, it didn't account for the actual window focus; it would
just assume that it was focused.

The result was that the perceived focus would alternate between each of
the windows in the wezterm process, and if you were running an
application that had enabled focus tracking, those events could cause a
repaint and drive up the CPU utilization.

This commit addresses that by gating the focus update to only occur
when we have the focus, and for extra safety, avoid generating focus
events at the terminal layer if the new state matches the current state.

a7cdd46720 logging: use our own custom logger
I wanted to use the Target::Pipe feature of env_logger so that we could
log to a log file as well as stderr, but it just doesn't work
(https://github.com/env-logger-rs/env_logger/issues/208).

Since we were already composing over the top of the logger in order
to capture data for our ringlog, this commit embraces that and makes
our logger responsible for both stderr and log file printing.

Thankfully, we can use the filter parsing code from env_logger to
avoid having to get too crazy with this.

Logs are stored in the runtime directory and look something like:

/run/user/1000/wezterm/wezterm-gui-log-596324.txt

Logs are collected on all platforms.

There isn't currently a thing to clean up logs.

526cc26b1e allow disabling aa for custom block glyphs
This is definitely in the band-aid category, but two issues have
mentioned the AA in custom block glyphs recently.

This commit adds an `anti_alias_custom_block_glyphs` option that can be
set to false to prevent the custom block glyphs from enabling AA.

I think a better long term fix would be some kind of hinting to avoid
the degenerate AA case, but when I made an enquiry about this class of
issue in tiny skia in the past, the author didn't want to diverge from
skia-compatible behavior, so I think we'd need to find (or build!) an
alternative rasterizer for these path instructions.

54d503de9d keys: add ActivateKeyTable assignment
`ActivateKeyTable` pushes a new named key table entry onto the stack.

It has some parameters:

* name - required; the name of a entry in `key_tables` that should be
  activated.
* timeout_milliseconds - how long the entry should remain active.
  When this duration elapses, the entry will pop itself from the
  stack. If omitted, the entry will not pop itself due to time.
* one_shot - if true (or omitted; true is default), the entry will pop
  itself after one use.  If false the entry will not pop itself after use.
  But note that if timeout_milliseconds is set then it may pop itself
  due to time.
* replace_current - if true, will pop the current stack entry before
  activating the current entry. Most useful when combined with some
  other one_shot=false activation.

`PopKeyTable` explicitly pops the top of the key table stack.
Most useful with `one_shot=false` activations.

`ClearKeyTableStack` clears the key table stack. Most useful with
`one_shot=false` activations.

```
local wezterm = require 'wezterm';

wezterm.on("update-right-status", function(window, pane)
  local name = window:active_key_table()
  if name then
    name = "TABLE: " .. name
  end
  window:set_right_status(name or "")
end);

return {
  debug_key_events = true,
  keys = {
    -- Activate the "woot" table as a one-shot with
    -- a 2 second timeout, after which it will restore
    -- the default table.

        }
      }
    },

    -- Activate the "woot" table.
    -- The table will remain active until explicitly popped
    -- by the `PopKeyTable` action. See the Escape binding below!

      }

14323a08d1 fonts: adjust descender for scaled fallback fonts
The gist of the issue is that when setting eg: scale=1.2 to draw
a larger CJK glyph, it is drawn at the same descender level, which
makes it more likely to leave the top of the cell.

This commit adjusts the y position by the difference between the
original and the scaled descender so that is less likely to cause
problems.

bd02d33bf5 tab bar: constrain to constant height
The tab bar height could vary by a couple of pixels depending on the

A bit of a PITA, this commit:

* Introduces a DeferredKeyCode type that defers resolving a concrete

* Adds key_map_preference config which can be Mapped or Physical
* Key map building resolves the keycode using key_map_preference
* Default key assignments have been re-phrased in order to produce
  DeferredKeyCodes
* User-specified keys without `mapped:` or `phys:` prefixes will
  resolve according to key_map_preference

210999b915 clipboard: restructure how we capture OSC 52
Previously, we'd create a clipboard handler associated with a GUI window
and take care to pass that down to the underlying Pane whenever we
spawned a new pane.

For the mux server, instead of being associated with a GUI window, the
clipboard was a special RemoteClipboard that would send a PDU through
to the client that spawned the window.

The bug here was that when that client went away, the clipboard for
that window was broken.

If the mux server was the built-in mux in a gui process this could
leave a tab without working OSC 52 clipboard support.

This commit restructures things so that the Mux is responsible for
assigning a clipboard handler that rephrases the clipboard event
as a MuxNotification.

Both the GUI frontend and the mux server dispatcher already listen
for mux notifications and translate those events into appropriate
operations on the system clipboard or Pdus to send to the client(s).

808d7df8d4 gui: fixup tab bar height issue
In https://github.com/wez/wezterm/pull/1779#issuecomment-1082058134 we
discuss a weird case where the tab bar height is computed as 0 and then
gets stuck at 0.

What's happening is that the initial `TabBarState::default()` value has
no items yet, and `build_fancy_tab` generates an area that occupies 0
pixels.  This computed element is cached, and then the height from that
is cached.

When `invalidate_fancy_tab` is called, it didn't invalidate the cached
height and the resultant metrics were wonky.

One possible fix for this was to also invalidate the cached height,
but since that height is already stored in the built fancy tab,
we can remove that derived-cached value in favor of just passing
down the value.

d0a7fc9fd3 gui: take a run at rendering double-width/height lines
This is using the existing attributes on the lines and rendering
the lines with doubled dimensions.

Selection on double width lines is a bit wonky because we don't
know how to translate the column position correctly.

8cb74c62d2 allow setting selection colors with alpha values
This commit allows the following configuration:

```
wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }'
```

which sets the selection_bg to fully transparent, and selection_bg to
50% transparent gray.

When selection_fg is fully transparent we'll use the normal fg color.

When selection_bg is partially (or fully!) transparent, it will be
alpha blended over the current cell background color.

To support this, the config file will now accept rgba colors specified
as 4 whitespace delimited numeric values. If a value ends with `%` it
is interpreted as a number in the range 0-100.  Otherwise, it is
interpreted as a number in the range 0-255.  The 4 values are
red, green, blue, alpha.

At this time, only the selection_fg and selection_bg settings accept
alpha values.

bd47979292 revise ligature render / cursor intersection
This puts to final rest #478, wherein ligatured glyphs that span
cells would render portions of the glyph with the wrong fg color,
where wrong was usually the bg color and cause the glyph to turn
invisible when cursoring through the ligature.

The approach used here is to divide the glyph into 7 discrete strips
where each strip either intersects with the cursor, the selection, or
neither. That allows us to render each strip with the appropriate
foreground color.

This change simplifies some of the logic and allows some other code
to be removed, so that feels good!

As is tradition with these renderer changes, there's a good chance that
I overlooked something in testing and that the metrics or alignment
might be slightly off for some font/text combo.  Let's see how this
goes!

1e32ccbd2f shaping: fix an issue where we'd lose combining marks like U+20d7
For a sequence like `e U+20d7` the intent is to render the `e` with
a vector arrow over the top.

This is typically implemented by fonts as an `e` followed by the
vector glyph (or vice versa), where either one of those may have
a zero advance so that the two elements are combined.

There were two problems here:

* During shaping we'd see the zero advance and assume that the entry
  was useless and skip it
* During rendering, if we didn't think it had any cell width, we'd
  not render it

Cursoring through that particular sequence can hide the vector
mark if the cursor is set to the default block cursor due to annoyances
in how the block cursor is rendered (it changes the fg color to match
the bg, but for elements outside where we think the cursor is, this
makes those elements invisible).

9de0e1ac90 shaping: improve glyph cell width math
This is a more robust approach; we make a separate pass to figure
out information about the (harfbuzz) cluster for a sequence of glyphs,
and then map that sequence back to the original cell sequence, and
from there compute the total cell width for the run, then distribute
the glyphs across the run.

This should yield more sane results for bidi.

Fixup the x-position math; it was still wonky despite the
efforts in 5f2c905db8 and

5f2c905db8 shaping: feed presentation width from the terminal through to glyph info
This allows unicode_version to be respected again when rendering.

The updated emoji-presentation.sh script now highlights this slightly
better by putting `.` characters after the emoji; unicode version 14
emoji presentation will show the `.` in the 3rd column, while earlier
versions will show it in the 2nd column for glyphs that are sensitive
to the version.

cf518c9186 fun with sticky bits and RUNTIME_DIR
This commit does two related things, from opposite ends of the spectrum:

* Sets the sticky bit on pid files and unix sockets to avoid tmpwatch
  deleting them in cleanup scenarios
* Falls back to looking at the changed time if the filesystem doesn't
  support reporting creation time when wezterm does its own liveness
  and cleanup checks for unix domain sockets in the runtime dir
* Allow any wezterm instance to perform that cleanup

98f35bbf24 bidi: tag Line with bidi mode
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.

0324ff66f0 wezterm: add experimental_bidi config option and very basic bidi
This commit is larger than it appears to due fanout from threading
through bidi parameters.  The main changes are:

* When clustering cells, add an additional phase to resolve embedding
  levels and further sub-divide a cluster based on the resolved bidi
  runs; this is where we get the direction for a run and this needs
  to be passed through to the shaper.
* When doing bidi, the forced cluster boundary hack that we use to
  de-ligature when cursoring through text needs to be disabled,
  otherwise the cursor appears to push/rotate the text in that
  cluster when moving through it! We'll need to find a different
  way to handle shading the cursor that eliminates the original
  cursor/ligature/black issue.
* In the shaper, the logic for coalescing unresolved runs for font
  fallback assumed LTR and needed to be adjusted to cluster RTL.
  That meant also computing a little index of codepoint lengths.
* Added `experimental_bidi` boolean option that defaults to false.
  When enabled, it activates the bidi processing phase in clustering
  with a strong hint that the paragraph is LTR.

This implementation is incomplete and/or wrong for a number of cases:

* The config option should probably allow specifying the paragraph
  direction hint to use by default.
* https://terminal-wg.pages.freedesktop.org/bidi/recommendation/paragraphs.html
  recommends that bidi be applied to logical lines, not physical
  lines (or really: ranges within physical lines) that we're doing
  at the moment
* The paragraph direction hint should be overridden by cell attributes
  and other escapes; see 85a6b178cf

and probably others.

However, as of this commit, if you `experimental_bidi=true` then

```
echo This is RTL -> عربي فارسی bidi
```

(that text was sourced from:
https://github.com/microsoft/terminal/issues/538#issuecomment-677017322)

then wezterm will display the text in the same order as the text
renders in Chrome for that github comment.

This isn't ideal, but it is better than previously: we would
close the window and before the Drop impl had updated the
list of known windows, we'd try to re-assign that window
to another mux window in a different workspace, but it would

The optional spawn parameter can be used to launch a specific

will be used.

The gui only supports a single active workspace. Switching workspaces
will repurpose existing gui windows and re-assign them to windows
in the new workspace, adjusting their size to fit those windows,
spawning new windows or closing unused windows as required.

The gui now exits when there are no panes in the active workspace,
rather than no panes at all.

The mux now has a notion of which client is actively doing things.

58d969e77c gui: Avoid 450ms delay on startup(!)
In the case that the published symlink is stale, our default
client connection logic was to retry connecting with backoff
to give a newly spawned server a chance to startup.

In the context of a newly launched gui process checking to see
if an existing gui process can serve the same request, we don't
need to give it any grace: it will either answer immediately
or be deemed not useful.

This commit limits us to a single connection attempt in the case
where we're not automatically starting the server, which in turn
constrains the overhead to something in the order of microseconds
rather than nearly 0.5 seconds.

While we're in here, I noticed that if we thought we had a socket
to try and that failed, we'd always try to publish a new symlink.
However, if we failed due to mismatched version info, we shouldn't
publish over the top of the already running instance.

1fd53d4a5d mux: propagate User Vars across to the client
user vars were stubbed out.  This commit adds storage for them
in the mux client and adds a new notification that publishes each
var as it is changed.  That differential stream is applied to the
storage in the mux client when it is received.

```lua
local wezterm = require 'wezterm'

wezterm.on("update-right-status", function(window, pane)
  local woot = pane:get_user_vars().woot
  window:set_right_status(tostring(woot))
end);

return {
  unix_domains = {
    {name="unix"},
  },
}
```

then running:

* `wezterm connect unix`
* in that session: `printf "\033]1337;SetUserVar=%s=%s\007" woot `echo -n nice | base64``

causes `nice` to show in the status area.

0e9924e585 new: WslDomain, a variant on the local domain
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

4524abcdba gui: revise win32-input-mode flow
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.

b05cb1241e force clusters to break around cursor boundary
When rendering the IME composing text, I noticed that for the Korean
input sequence: shift+'ㅅ' followed by 'ㅏ' we'd render the 'ㅆ' (the
shifted first character) in black and the composing 'ㅏ' in white
against the cursor color, and that was very difficult to read,
especially at the default font size.

To resolve this, this commit:

* Forces clustering to break around the cursor boundary, so that
  we treat the cursor position as its own separately styled cluster
* Adjusts cursor/bg rendering so that we always consider the start of
  the cluster for the colors of that run.  We are guaranteed that a
  ligatured sequence will fit in the background area anyway.

This has the effect of "breaking" programming ligatures such as '->'
when cursoring through them, and decomposing them into their individual
'-' and '>' glyphs, which is a reasonable price to pay for being able
to see things better on screen.

71dae34b75 macos: improve IME handling
For Korean text input, pressing SHIFT and then typing in certain
keys begins a composition sequence.  Our logic for when to route
via the IME got so distracted by ALT that it didn't consider SHIFT
and didn't send this sequence to the IME, so we'd fail to compose
those sequences.

While poking at this, I realized that we should treat this composition
similarly to dead keys, in that we can signal the term window to
highlight the cursor color and report that status.

There's some further work to do: the composing text should be rendered
by us.  So far our IME integration assumes that the IME itself will
render over the top of our window, but for this particular input
it doesn't do that.

5f26746286 window/gui: remove raw/phys fallback fields from KeyEvent
Since we now have RawKeyEvent and a sane way to indicate handling,
we don't need these any more, and it simplifies key dispatch to
remove them.

0224f65fed gui: avoid glitchy live resize
Pass down whether we are in a live resize to the gui layer, so that
we don't incorrectly assume that the scale has changed, and fight
with the window manager.

Built this on my mac: will need to fixup for windows and linux.

028026049d add window:dead_key_is_active window:leader_is_active
This commit adds a couple of helper methods that provide insight into
the state of the keyboard layer.

The intent is for users to add status information about the keyboard
state.

This commit also ensures that we schedule an update when the leader
key duration expires, and ensures that we close out the leader state
for an invalid key press.

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

wezterm.on("update-right-status", function(window, pane)
  local leader = ""
  if window:leader_is_active() then
    leader = "LEADER"
  end
  local dead = ""
  if window:dead_key_active() then
    dead = "DEAD"
  end
  window:set_right_status(leader .. " " .. dead)
end);

return {
  leader = { key="a", mods="CTRL" },
  colors = {
    dead_key_cursor = "orange",
  },
}

or leader key processing.

d5726ba91a window: add RawKeyEvent concept
on macos only (for now), we generate a RawKeyEvent prior to
dead key or IME composition and route it to the window to give it
a chance to handle the event.

RawKeyEvent handling is scoped only to key assignments, not generating
input for the terminal.

A raw key event can be marked as handled to prevent moving on to
performing composition and generating cooked key input.

69e8d9144c gui: allow matching keys with a physical position
```lua
local wezterm = require 'wezterm'

return {
  debug_key_events = true,
  keys = {
    {key="phys:Q", action=wezterm.action{SendString="woot"}},
  },
}
```

The above will send "woot" to the pane whenever the key in same
physical position as Q on an ANSI standard US keyboard is pressed.

7e8e215dc7 gui: remove adjust from vertex
This comes from a time where our quads were always locked to grid
positions.  We don't need it any more: we can simply add the adjustments
to the quad positions that we set.

Removing it makes the vertex a bit smaller and reduces the amount
of GPU accessible memory we need to use.

1e7d552844 fonts: replace font_ptr with a font id
I'm running down a weird thing where the main font renders weirdly
when the title font is 12 pt vs the main font 10 pt.

I thought there might have been a cache invalidation issue and
realized that we could have an A-B-A style issue with the font_ptr
stuff, so I replaced it with an incrementing id.

That didn't fix the thing I was looking at, but does feel a bit
nicer overall.

00a393b3d1 gui: bundle and use Roboto for title font on Linux + Windows
The default we use on macOS looks decent.  Roboto is a similar
looking font that we can use for the other platforms.
I may make it the same on all three once I've had a chance
to compare it on a mac.
