WindowState is a bitfield that can represent maximized, full screen
and hidden window states.
WindowState is passed along with resize events, improving on the
prior basic is_full_screen boolean by representing the other states.
Notably, WindowState::MAXIMIZED is used to represent a state where
the window's size is constrained by some window environment function;
it could be due to the window being maximized in either or both the
vertical or horizontal directions, or by the window being in a tiled
state on any edge.
When the window is MAXIMIZED, wezterm will behave as though
`adjust_window_size_when_changing_font_size = false` because it knows
that it cannot adjust the window size in that state.
This potentially helps with #695, depending on whether the window
manager propagates this state information to wezterm. Gnome/mutter
does a good job at this with both X11 and Wayland, but I couldn't get
sway to report these states and I don't know of any other tiling wm
that I can easily install and use on fedora, so there's a question
mark around that.
This commit causes a window-config-reloaded event to trigger
when the appearance (dark/light mode) is changed on macos.
It also arranges to propagate the window level config to newly
spawned panes and tabs, created both via the gui and via the
CLI/mux interface.

I added this originally thinking that it would make it easier to resolve
https://github.com/wez/wezterm/issues/695 and to integrate wgpu support,
but it's the cause of https://github.com/wez/wezterm/issues/922 so let's
take it out and more directly connect the window events to those in the
terminal.
This commit likely breaks mac and windows; pushing it so that I can
check it out and verify on those systems.
Removes the callbacks type and replaces event dispatch with
an async capable channel.
This makes it a bit simpler to model some of the window internals,
and to prepare for a wgpu enabled future.
This changes have been tested only on linux so far.
This is to support <https://github.com/wez/wezterm/issues/291>.
The window resized event happens asynchronously wrt. processing
a window resize, triggering at the end of the normal window
resize handling.
This commit introduces the notion of whether we are in full screen
mode or not in the underlying event callback, which is useful to
gate the desired feature, which is: when in full screen mode,
increase the padding for the window to center its content.
While poking around at this, I noticed that we weren't passing
the per-window config down to the code that computes the quad
locations for the window.
This commit also changes the font size increase/decrease behavior
so that in full screen mode it doesn't try to resize the window.
```lua
local wezterm = require 'wezterm';
wezterm.on("window-resized", function(window, pane)
local window_dims = window:get_dimensions();
local pane_dims = pane:get_dimensions();
local overrides = window:get_config_overrides() or {}
if not window_dims.is_full_screen then
if not overrides.window_padding then
-- not changing anything
return;
end
overrides.window_padding = nil;
else
-- Use only the middle 33%
local third = math.floor(window_dims.pixel_width / 3)
local new_padding = {
left = third,
right = third,
top = 0,
bottom = 0
};
if overrides.window_padding and new_padding.left == overrides.window_padding.left then
-- padding is same, avoid triggering further changes
return
end
overrides.window_padding = new_padding
end
window:set_config_overrides(overrides)
end);
return {
}
```
The opengl based render first clears the window to the background
color and then renders the cells over the top.
on macOS I noticed a weird lighter strip to the bottom and right of
the window and ran it down to the initial clear: our colors are SRGB
rather than plain RGB and the discrepancy from rendering SRGB as RGB
results in the color being made a brighter shade. This was less
noticeable for black backgrounds.
The future won't ever complete if you don't connect the waker
from the context!
Prove this out by making the windowops functions async and
verifying them in the async example
