It's been replaced with an opaque termwiz error type instead.
This is a bit of a more conservative approach than that in (refs: #407)
and has less of an impact on the surrounding code, which appeals to
me from a maintenance perspective.

wezterm sets a more restrictive umask (`0o077`) by default so that any files
that it creates (eg: unix domain socket, log files) are more secure
by default.
However, some environments rely on the more general default of (`0o022`)
without checking that it is set.
This matters because programs spawned by wezterm inherit its more
restricted umask.
I hadn't noticed this because I've had `umask 022` in my shell RC files
since sometime in the 1990's.
This commit adds some plumbing to the pty layer to specify an optional
umask for the child process, and some more to our umask saver helper
so that any thread can determine the saved umask without needing a
reference to the saver itself, which may be in a different crate.
The logic in the config crate has been adjusted to connect the saved
value to the default command builder arguments.
The net result of this is that running `wezterm -n start bash -- --norc`
and typing `umask` in the resultant window now prints `0022`.

This allows us to support the kitty style underline sequence,
or the : separated form of the true color escape sequences.

When running the GUI, we generate a unix domain socket path for
the current process and start up a mux server for that path.
This allows `wezterm cli list` and `wezterm cli split-pane` to
work implicitly inside the GUI session.
When started in this way, the mux server is not persistent;
when the GUI process is terminated, all of its windows, tabs
and panes are terminated.

* Allow injecting some initial output to new panes
* Have the update checker set this new-pane-banner to a short
upsell to let the user know there is an update.
* Refactor toast notifications into their own crate
* Have the update checker call a new stub function that triggers
a toast notification with an URL... but it does nothing because
the rust ecosystem doesn't support this on macos yet and I'm
writing this code there
Tidies up the plumbing around pixel dimensions so that ImageData

I put this together to play with sticking the wezterm logo in
the close confirmation dialogs. I didn't end up using that though,
but have preserved the commented code for use in future hacking.
80214319ae broke the use of RUST_LOG to
turn up trace logging.
This commit refactors logger initialization into the env-bootstrap crate
so that it is centralized, and adopts the use of `WEZTERM_LOG` to
override the default logging filters, rather than `RUST_LOG`.
My original goal was to update to allsorts 0.5 but the API
changes are significant and not clearly described.
To make that transition easier, the prior commit moved the shaping
logic into our allsorts shaper module, leaving the name parsing
here in parser.rs.
This commit now replaces that logic with ttf_parser, which is
potentially faster (there's more emphasis on optimal code in that
crate than in allsorts) but definitely simpler.
It's not a slam-dunk transition: ttf_parser doesn't know how to
decode MacRoman encoded text, so there's a bit of logic borrowed
from allsorts here to handle that.
I'm gradually improving snapshot testing macro devx in k9 and preparing
to ship v1. Before i do this i'm changing the inline snapshot macro to be
just `snapshot!()` that takes `Debug` trait an an arg and figures out
serialization of it.
This commit adjusts the default color palette to use the same color
cube calculation as xterm; it isn't the ideal color cube calculation
and results in slightly brighter colors.
This commit also memoizes the default palette calculation so that
it isn't recomputed each time a palette is created.

This commit is a bit noisy because it also meant flipping the key map
code from using the termwiz input types to the window input types, which
I thought I'd done some time ago, but clearly didn't.
This commit allows defining key assignments in terms of the underlying
operating system raw codes, if provided by the relevant layer in the
window crate (currently, only X11/Wayland).
The raw codes are inherently OS/Machine/Hardware dependent; they are the
rawest value that we have available and there is no meaningful
understanding that we can perform in code to understand what that key
is.
One useful property of the raw code is that, because it hasn't gone
through any OS level keymapping processing, its value reflects its
physical position on the keyboard, allowing you to map keys by position
rather than by value. That's useful if you use software to implement
eg: DVORAK or COLEMAK but want your muscle memory to kick in for some of
your key bindings.
New config option:
`debug_key_events = true` will cause wezterm to log an "error" to stderr
each time you press a key and show the details in the key event:
```
2020-12-06T21:23:10.313Z ERROR wezterm_gui::gui::termwindow > key_event KeyEvent { key: Char('@'), modifiers: SHIFT | CTRL, raw_key: None, raw_modifiers: SHIFT | CTRL, raw_code: Some(11), repeat_count: 1, key_is_down: true }
```
This is useful if you want to figure out the `raw_code` for a key in your
setup.
In your config, you can use this information to setup new key bindings.
The motivating example for me is that because `raw_key` (the unmodified
equivalent of `key`) is `None`, the built-in `CTRL-SHIFT-1` key
assignment doesn't function for me on Linux, but I can now "fix" this in
my local configuration, taking care to make it linux specific:
```lua
local wezterm = require 'wezterm';
local keys = {}
if wezterm.target_triple == "x86_64-unknown-linux-gnu" then
local tab_no = 0
-- raw codes 10 through 19 correspond to the number key 1-9 positions
-- on my keyboard on my linux system. They may be different on
-- your system!
for i = 10, 20 do
table.insert(keys, {
key="raw:"..tostring(i),
mods="CTRL|SHIFT",
action=wezterm.action{ActivateTab=tab_no},
})
tab_no = tab_no + 1
end
end
return {
keys = keys,
}
```
Notice that the key assignment accepts encoding a raw key code using
a value like `key="raw:11"` to indicate that you want a `raw_code` of
`11` to match your key assignment. The `raw_modifiers` portion of
the `KeyEvent` is used together with the `raw_code` when deciding
the key assignment.

This tidies up the font-dir and built-in font management a little
bit and paves the way for codepoint -> font resolution for fonts
discovered in font-dirs.
This commit uses a bit of DirectWrite to discover which font(s)
can be used to render a set of codepoints.
While hooking this up, I found that the method we were using
to extract the font data didn't handle TTC data so this commit
improves some parser diagnostics and handling for that.

98f289f511 causes more metrics retrieval
than in earlier versions; each unchached glyph render would trigger
a metrics recompute for the relevant font.
Add a simple cache for this.

This is one of those massive time sinks that I almost regret...
As part of recent changes to dust-off the allsorts shaper, I noticed
that the harfbuzz shaper wasn't shaping as well as the allsorts one.
This commit:
* Adds emoji-test.txt, a text file you can `cat` to see how well
the emoji are shaped and rendered.
* Fixes (or at least, improves) the column width calculation for
combining sequences such as "deaf man" which was previously calculated
at 3 cells in width when it should have just been 2 cells wide, which
resulted in a weird "prismatic" effect during rendering where the
glyph would be rendered with an extra RHS portion of the glyph across
3 cells.
* Improved/simplified the clustering logic used to compute fallbacks.
Previously we could end up with some wonky/disjoint sequence of
undefined glyphs which wouldn't be successfully resolved from a
fallback font. We now make a better effort to consolidate runs of
undefined glyphs for fallback.
* For sequences such as "woman with veil: dark skin tone" that occupy a
single cell, the shaper may return 3 clusters with 3 glyphs in the
case that the font doesn't fully support this grapheme. At render
time we'd just take the last glyph from that sequence and render it,
resulting in eg: a female symbol in this particular case. It is
generally a bit more useful to show the first glyph in the sequence
(eg: person with veil) rather than the gender or skin tone, so the
renderer now checks for this kind of overlapping sequence and renders
only the first glyph from the sequence.
The current master of allsorts supports color fonts in both bitmap and
svg varieties. I'm interested to see if I can teach wezterm to render
the svg based variety in a subsequent diff.
First though, it's times to dust off our allsorts shaper logic.
This commit updates to point to the current master of allsorts at the
time of writing; there's a little bit of API fanout that makes it a bit
easier to manage font fallback.
The fallback logic has been improved so that we can now successfully
fall back to the emoji font.
The shaping logic has been improved so that we turn on the options that
enable ZWJ for combining sequences of emoji, such as "man health
worker".
Running with the allsorts shaper enabled produces generally superior
emoji/ligature substitution results compared to harfbuzz with Noto Color
Emoji; the "man health worker" and the flags (eg: `flag: England`) from
the subdivsion-flag section don't get substituted at all with harfbuzz,
but do produce appropriate glyphs with allsorts.

This causes `tmux -CC attach` to enter control mode and patch
into the terminal, printing out parsed event messages.

This command formats an OSC 7 escape sequence to inform the terminal
of the working directory.
It has two optional arguments:
* The hostname - if unspecified the hostname of the system will be used
* The working directory - if unspecified the working directory of the
process will be used
This command formats the hostname and working directory into a `file://`
URL and emits an OSC 7 escape sequence.
The intent of this is to make it a bit easier to produce shell
integration scripts for various shell environments without trying
to implement URL encoding in eg: bash.
Adds some supporting methods for computing the `SemanticZone`s
in the display and a key assignment that allows scrolling the
viewport to jump to the next/prev Prompt zone.
This commit introduces a small, bounded, LRU cache for recently
decoded images.
This allows the same image ID to be used in the cache that the
same image bits are repeatedly sent to the terminal.
This is advantageous because it reduces the amount of texture
space required by the gui layer.
This wasn't used by anything and the version was getting pretty stale.
Upgrading is awkward because newer versions pull in an incompatible
freetype library version.
This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.

This commit uses the guillotine algorithm to assign rectangles,
which is superior to the dumb algorithm previously in use.
In addition, in the first pass of painting, if we get a texture
space error, we clear the atlas and try again without increasing
it size, which should serve as the ultimate defrag.
Subsequent passes will cause the texture to grow if needed.
