When `parse_first_as_vec` is parsing an OSC sequence (e.g.
`SetHyperlink`) that is terminated by the escaped form of ST (`ESC \`),
ensure that the ST sequence is included in the returned vector.
This is achieved by ensuring the VTParser has returned to the "ground"
state: i.e. the stored state after the `ESC` is processed is not enough
for `parse_first_as_vec` to terminate. We must also parse the `\` to
ensure that we return a complete span to the caller.

This doesn't really change any behavior, but adjusts the types
such that CSIs that set colors have the potential to track the
alpha channel and that can make it through to the GUI/render layer.
When adding sparse ranges the cartesian product of range combinations
was explored to find intersections, which is pretty awful if there
are 1 million entries to be inserted.
This commit employs binary search to reduce the complexity, at
the expense of requiring that the internal range array is sorted.
Adds the option to use an alternative clusted line storage for
the cells component of the line.
This structure is not optimal for mutation, but is better structured
for:
* matching/extracting textual content
* using less memory than the prior simple vector
For some contrast: the line "hello" occupies 5 Cells in the cell based
storage; that 5 discrete Cells each with their own tiny string
and a copy of their attributes.
The clustered version of the line stores one copy of the cell
attributes, the string "hello" and some small (almost constant size)
overhead for some metadata. For simple lines of ascii text, the
clustered version is smaller as there are fewer copies of the cell
attributes. Over the span of a large scrollback and typical terminal
display composition, this saving is anticipated to be significant.
The clustered version is also cheaper to search as it doesn't require
building a copy of the search text for each line (provided the line is
already in clustered form).
This commit introduces the capability: none of the internals request the
new form yet, and there are likely a few call sites that need to be
tweaked to avoid coersion from clustered to vector form.
Various color schemes have been duplicated as they have been added to
different scheme collections. They don't always have identical names
(eg: some remove spaces) and sometimes they have very different names
(eg: _bash vs. nightfox, or Miu vs. Blazer).
We already detected duplicates from different collections but previously
we would omit those dupes.
This commit allows us to track those duplicates by recording their
aliases.
When we write out our data, we only include "interesting" alias names;
those where the name isn't trivially identical.
Some scheme collections (eg: iterm2 color schemes) have duplicates
(eg: zenbones and zenbones_light are identical) and we have previously
shipped with both of those names, so we special case to emit dupes
for which we have prior version information in order to avoid
breaking backwards compatibility for our users.
In the doc generation we can generate links to the aliases if we
included them, but also note about the other names and how we don't
include them. That is so that someone searching the docs for say
"_bash" can discover that it is actually a duplicate of "nightfox" and
use nightfox instead.
Adjust importer to read directly from the source .itermcolors
files in the upstream repo. Extract some author information
from the comments in those files.
All data is now fetched (and cached!) via relatively minimal
http requests rather than requiring a git repo locally.
Also search for .yml files in base16 repos; found another
couple of schemes this way.
The toml files under assets/colors are no longer read by
anything in the repo. I plan to remove them, but since the
docs reference them as examples, I will first ensure that
there are docs and tooling that explains how to write and
share your own scheme files.
wezterm.color.parse() returns a color object that can be assigned in the
wezterm color config, and that can be used to adjust hue, saturation and
lightness, as well as calculate harmonizing colors (complements, triads,
squares) from the RGB/HSL color wheel.
This commit expands the toml file definition to include
metadata for the origin url, author and name.
A new sync utility fills out that metadata when it pulls from the iterm2
color schemes repo.
The utility also pulls down the scheme data json maintained by
the Gogh project: https://gogh-co.github.io/Gogh/ and converts
it to wezterm's format.
About 50% of Gogh overlaps with iterm2; we take the iterm2 versions
of those schemes by default because the iterm2 data has more info
about things like cursor and selection colors.
The sync utility is responsible for compiling the de-duplicated
set of scheme data into a form that is used by wezterm and its
docs.
Currently implemented on X11 only, this function returns information
about the geometry of the screen(s).
This is taken from the same source of information we use for the
`--position` CLI argument to `wezterm start`.

Using the newly exposed-to-lua mux apis, you may now run some lua code
at GUI startup and/or mux startup, just prior to any default windows
being created.
If you happen to spawn any panes as a result of this, wezterm will
skip creating the default program.
```lua
local wezterm = require 'wezterm'
local mux = wezterm.mux
-- This produces a window split horizontally into three equal parts
wezterm.on("gui-startup", function()
wezterm.log_info("doing gui startup")
local tab, pane, window = mux.spawn_window{}
mux.split_pane(pane, {size=0.3})
mux.split_pane(pane, {size=0.5})
end)
wezterm.on("mux-startup", function()
wezterm.log_info("doing mux startup")
local tab, pane, window = mux.spawn_window{}
mux.split_pane(pane, {size=0.5, direction="Top"})
end)
return {
unix_domains = {
{name="unix"}
},
}
```

The intent is to expose Mux related functions to lua, so `wezterm.mux`
will be that module table.
In order to test this out in the debug overlay, I realized that the
overlay was running functions in a different thread and didn't have
access to the mux, so this commit also tweaks the debug overlay repl to
execute the input in the main thread.
The result is that it is now possible to do
`wezterm.mux.active_workspace()` in the debug overlay to print the
active workspace name.
More functions will follow.

Main thing to note here is that the open crate has deprecated
open::that_in_background, but made open::that non-blocking.
I think this is OK, but I'm a little cagey about what will
happen with this on Windows. We may need to spawn our own
thread for this if things go awry.
This allows moving past a number of outdated deps, but importantly,
allows updating miow to a version that has the correct memory layout
for SocketAddr, and satisfies a dependabot alert.
This appeases some dependabot warnings regarding the use of
an old version of parking_lot that has some unsoundness issues.
ratelimit_meter is frozen and is succeeded by governor which has
a mostly similar API.
