back out the portion of the cap height scaling that applied when
we knew the cap height of the primary font but not a fallback font.
That logic allowed some overly wide powerline fonts to be sized
correctly (a bit smaller), but also meant that a number of emoji

It now outputs something that you could conceivably put into
your config file, although the intent is to show the canonical
way to reference the individual fonts that were found, rather
than to specify a fully baked list to paste into a config.
eg:
```
; ./target/debug/wezterm ls-fonts
Primary font:
wezterm.font_with_fallback({
-- /home/wez/.fonts/OperatorMonoSSmLig-Medium.otf, FontDirs
{family="Operator Mono SSm Lig", weight="DemiLight"},
-- /home/wez/.fonts/OperatorMonoSSmLig-Medium.otf, FontConfig
{family="Operator Mono SSm Lig", weight="DemiLight"},
-- /home/wez/.fonts/MaterialDesignIconsDesktop.ttf, FontDirs
"Material Design Icons Desktop",
-- /home/wez/.fonts/terminus-bold.otb, FontDirs
{family="Terminus", weight="Bold"},
-- /home/wez/.fonts/JetBrainsMono-Regular.ttf, FontDirs

-- /home/wez/.fonts/NotoColorEmoji.ttf, FontDirs

})
```
we now compute the ratio of the cap height (the height of a capital
letter) vs. the em-square (which relates to our chosen point size) to
understand what proportion of the font point-size that a given font
occupies when rendered.
When rendering glyphs from secondary fonts we can use the cap height
ratios of both to scale the secondary font such that its effective
cap height matches that of the primary font.
In plainer-english: if you mix say bold, italic and regular text
style in the same line, and you have different font families for
those fonts, then they will now appear to be the same height where
previously they may have varied more noticeably.
For emoji and symbol fonts there may not be a cap-height metric
encoded in the font. We can however, improve our scaling: prior
to this commit we'd use the ratio of the cell metrics of the two
fonts to scale the icon/emoji glyph, but this could cause the glyph
to be slightly oversized as seen in https://github.com/wez/wezterm/issues/624
If we know the cap-height of the primary font then we can additionaly
apply that factor to scale the emoji to better fit the cell.
While looking at this, I noticed that the aspect ratio calculation
for when to apply to the allow_square_glyphs_to_overflow_width option
had width and height flipped :-(

This commit allows the x11 window implementation to detect changes
in the DPI that occur after a window is created.
These can occur when changing desktop resolution or when changing
the accessibility option for "Large Text" in gnome.
In order to avoid continually polling for the value on every resize,
we look for the `_GTK_EDGE_CONSTRAINTS` atom in our property change
notifications. This seems to be sent at least as often as the
dpi/scaling changes.
It's also worth noting that some dpi changes don't generate resize
events, so we can't just read the dpi value on every resize, because
we'd miss some of those changes.
Part of this commit changes the font scaling logic: previously
we'd keep a notion of "dpi scale" to apply. That dates from an
earlier time in wezterm where we didn't think that we knew an
actual dpi value.
The way that worked was that we'd compare our current guestimate
of the DPI against what we though the baseline OS dpi should be to
produce a scaling factor.
On X11 that dpi value is global and we'd effectively always produce
a revised scaling factor of 1 after we'd set up the initial window.
This commit changes that logic to just pass down the actual DPI value
to the font code. That DPI value already accounts for HiDPI scaling
so this is hopefully a NOP change for the other systems.

This was broken by b441be3ac9
For whatever reason, the breakage was only visible with the Iosveka
font on Windows. I couldn't reproduce it on my other systems, even
though the code technically applies to any system.
The breakage was: the metrics resulted in a difference of about 0.4
pixels being used for the descender with that particular font, resulting
in weird vertical alignment problems.
The offset needs to be computed against the ceil of the cell height,
which removes the fractional offset.

This has been a commonly requested feature in the past week,
and it's a reasonable one. The mux server inherited the
close-when-done behavior from when it used to be an alternate
front-end in the same executable as the gui, but it doesn't
need to be that way any more.
We also need to accomodate that case in the client: if the
newly attached domain doesn't result in any panes being imported,
we need to spawn a new command there in order to keep the client
alive. The pre-existing check for whether the mux was empty had
false positives because the local mux may still reference the
pane from the connection UI, which would finish closing out shortly
after we had decided not to spawn anything, and then the client
would close.

This replicates `last-window` in tmux. To pull this off, I

Rust 1.51 allows addressesing a long-standing TODO which was that we
shouldn't need to build a vendored copy of openssl on most sensible unix
systems.
We do require a vendored copy on macOS and Windows, but due to the way
that Cargo's feature resolver worked, it wasn't possible for this
requirement to be respected.
Rust 1.51 introduces `resolver="2"` which can deal with this feature
resolution!
https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2
The upshot of this is that building wezterm on real unix systems that
are not macos will now link against the system libssl, resulting in both
a shorter compile time and less headaches arising from having a slightly
different openssl used by wezterm than the rest of the system.

There's something fishy with colorspaces and blending.
This commit removes the `window::Color` type and replaces
it and the confusing array of color types exposed by the
`palette` crate with a pair of much simpler types:
`LinearRgb` - a tuple of f32 linear color components
`SrgbaPixel` - the u32 sRGBA pixel representation
This doesn't change anything about rendering, it just
makes it a bit simpler and makes the SrgbaPixel -> LinearRgb
conversion happen slightly earlier which shaves off some
ad-hoc conversions.

Switches from using a dynamic vertex buffer to an immutable
vertex buffer. This feels counter-intuitive to me; the purpose
of dynamic is to sustain frequent updates, but mapping the buffer
needs to synchronize with the GPU, and if we are rapidly invalidating
the window that can stall painting by tens of milliseconds.
Switching to an immutable buffer avoids the stall and makes
quad mapping more consistently < 10ms, but its still not
ideal.

I'm not convinced that this is 100% good, but @fanzeyi reported
some latency when using tmux to mirror two sessions. The session
that was accepting interactive input responded quickly, but the
mirroring session was laggy.
This change connects the mux pane output event to window invalidation,
which should cause repaints to happen more often.
I couldn't reproduce the scenario above on my M1 mac, but that may
just be because M1 has dark magicks.
A casualty of b8dcfba9a4 was that
the decoded gif would get reset each time the texture filled up.
Take care to move that cached into the newly minted glyphcache.
Continuing along the same lines as the prior commit, the goal
of this commit is to remove the buffer transformation that was
part of uploading the texture to the GPU provided surface.
In order to do so:
* The sense of our local textures needs to change from bgra32 to rgba32.
bgra32 was a hangover from earlier versions of our window crate that
allowed direct-to-fb writes in software mode. We had to pick bgra32
for that for the broadest OS compatibility. I believe that that
constraint has been totally removed, although there is a chance that
this will flip the colors on macos.
* There was an additional linear-to-srgb conversion inlined in that
buffer transformation. I have no idea where that is needed because
the source data is carefully constructed as SRGB. I don't yet know
how to signal that, but for now I've moved that gamma correction
into the shader when we sample the texture.
With this change, timg playback now has vtparse as the hottest
region of code.
refs: #537
Two issues highlighted by profiling:
* Clearing the texture takes a non-trivial percentage of the profile.
The docs suggest that it is better to create a new texture than
to update large portions of a texture, so add some plumbing so
that we can do that in the first texture-full case.
* Next on the list is the code that translates from linear BGRA to
SRGBA. This is present for reasons that I believe are now legacy,
but for the moment: those two primitives now have faster and
easier implementations, so simplify to those.
This improves the timg video playback performance by ~10% for me.
refs: #537
I've been meaning to do this for a while; this commit moves
the escape sequence parsing into the thread that reads the
pty output which achieves two goals:
* Large escape sequences (eg: image protocols) that span multiple
4k buffers can be processed without ping-ponging between the
reader thread and the main gui thread
* That parsing can happen in the reader thread, keeping the gui
thread more responsive.
These changes free up the CPU during intensive operations such
as timg video playback.
This is a slight layering violation, in that this processing
really belongs to local pane (or any pane that embeds Terminal),
rather than generically at the Mux layer, but it's not any
worse a violation than `advance_bytes` already was.

While adding gif support I let this become unbounded.
This commit resolves that by categorizing images as either
single frame or animations.
Single frame images are decoded and held entirely in the texture
atlas, so occupy no additional space beyond the image file contents
and their sprite region in the texture atlas.
Animations are decoded into a set of frame bitmaps. There can be
up to 16 animations (each with their full set of frames) cached.
The individual frames may also exist within the texture atlas
if space permits.
refs: #534
https://i.giphy.com/media/3owvKqP4VSydZE4pvq/200w.gif cannot
be decoded as an animated gif due to this error: `No end code in lzw stream`
Ensure that we don't completely fail to process the render phase
as a result.
Previously, invalidation for animation was driven by the cursor
blink rate, which meant that animated gifs/pngs could not play
faster than 5fps (default blink interval is 200ms).
This commit calculates the next invalidation time based on the
closes next frame time of all animated cells in the viewport.
This is first draft; the animation rate is currently tied
to the cursor_blink_rate setting, so if the gif has frames that
are intended to display more frequently than that, they will
animate more slowly.
Animation is only carried out while the window has focus.
Animation increases the load on the GPU and thus uses more power.
It's kinda fun to stick one of these animated pixel gifs in the background:

During a live resize, we could queue up a lot of `window-resized`
events, which is undesirable.
This commit introduces a simple but effective mechanism to manage this;
a given event can have at most one executing and one pending copy.
So if we get a burst of resize events (eg: during a live window resize)
that might have previously queued hundreds of discrete events, we now
get a more manageable situation with 1 executing and 1 queued.
With this change, a given event can only have 1 executing instance at a
time (with the exception that the open-uri event doesn't go through this
mechanism).

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

This commit expands on the prior commits to introduce the concept
of per-window configuration overrides.
Each TermWindow maintains json compatible object value holding
a map of config key -> config value overrides.
When the window notices that the config has changed, the config
file is loaded, the CLI overrides (if any) are applied, and then
finally the per-window overrides, before attempting to coerce
the resultant lua value into a Config object.
This mechanism has some important constraints:
* Only data can be assigned to the overrides. Closures or special
lua userdata object handles are not permitted. This is because
the lifetime of those objects is tied to the lua context in which
they were parsed, which doesn't really exist in the context of
the window.
* Only simple keys are supported for the per-window overrides.
That means that trying to override a very specific field of
a deeply structured value (eg: something like `font_rules[1].italic = false`
isn't able to be expressed in this scheme. Instead, you would
need to assign the entire `font_rules` key. I don't anticipate
this being a common desire at this time; if more advance manipulations
are required, then I have some thoughts on an event where arbitrary
lua modifications can be applied.
The implementation details are fairly straight-forward, but in testing
the two examplary use cases I noticed that some hangovers from
supporting overrides for a couple of font related options meant that the
window-specific config wasn't being honored. I've removed the code that
handled those overrides in favor of the newer more general CLI option
override support, and threaded the config through to the font code.
closes: #469closes: #329
`wezterm`, `wezterm-gui` and `wezterm-mux-server` now all support
a new `--config name=value` CLI option that can be specified
multiple times to supply config overrides.
Since there isn't a simple, direct way to update arbitrary fields
of a struct in Rust (there's no runtime reflection), we do this
work in lua.
The config file returns a config table. Before that is mapped
to the Rust Config type, we have a new phase that takes each
of the `--config` values and applies it to the config table.
For example, you can think of configuration as working like this
if wezterm is started as `wezterm --config foo="bar"`:
```lua
config = load_config_file();
config.foo = "bar";
return config;
```
The `--config name=value` option is split into `name` and `value`
parts. The name part is literally concatenated with `config` in
the generated lua code, so the name MUST be valid in that context.
The `value` portion is literally inserted verbatim as the rvalue in the
assignment. Not quoting or other processing is done, which means
that you can (and must!) use the same form that you would use in
the config file for the RHS. Strings must be quoted. This allows
you to use more complicated expressions on the right hand side,
such as:
```
wezterm --config 'font=wezterm.font("Fira Code")'
```
The overrides stick for the lifetime of the process; even if
you change the config file and reload, then the value specified
by the override will take precedence.

This is defined as a trait method on Pane (default: false), and has the
obvious transitive equivalent methods in Tab and Window (eg: if all
contained items are `can_close_without_prompting`, then that container
is also `can_close_without_prompting`).
The intent is to avoid bothering the user to confirm closing a window
when the content is not stateful and doesn't warrant it.
For example: the window that is displayed in the event of a
configuration error really shouldn't prompt to the user to confirm
closing it.
All termwiztermtab panes are `can_close_without_prompting==true`
to effect this policy.
In the future, we could teach LocalPane to lookup the session leader
process against a list of "uninteresting" or "stateless" processes
and return an appropriate result (as suggested in

Refine the colorization logic to make it more of a blending operation.
Previously, we were relying on opengl to carry out blending between

This commit is inspired by this post:
https://www.puredevsoftware.com/blog/2019/01/22/sub-pixel-gamma-correct-font-rendering/

This appears to reduce the dark fringes/edges that we were seeing

https://learnopengl.com/Advanced-Lighting/Gamma-Correction suggests
some good practices:
* Only enable SRGB output on the final draw call, so that all prior
stages can operate on linear values and avoid converting to/from
linear multiple times.
* The SRGBA textures automatically linearize when sampled, but:
* The RGB data must be SRGB (non-linear)
* The A channel is assumed to be linear!
This commit nudges us closer to that by:
* Converting the freetype coverage map from its linear value to
non-linear when rasterizing.
* Splitting the shader files into one per stage (background, lines,
glyphs) and only setting outputs_srgb for the glyph stage

We weren't didn't treat the "No existing hyperlink, No new hyperlink"
case as no change in hyperlink, and were invalidating the window on
every mouse except for those over text with a hyperlink.
* Add cli option --config-file
* Update cli arg doc & make it conflict with skipping config
* When the config is given explicitly (either using --config-file or via WEZTERM_CONFIG_FILE), failing to load this file will use the default config.
* Otherwise the config file is searched one by one in a few directories.
This commit implements the deprecated NSUserNotification bits needed
to be able to handle clicking on a notification and open our choice
of URL.
Ideally we'd use the newer UserNotifications framework, but that
requires code signing.
Dead key processing respects the
`send_composed_key_when_left_alt_is_pressed` and
`send_composed_key_when_right_alt_is_pressed` options.
See doc changes included in this commit for more info.

This commit changes mouse-based selection and middle click to use the
PrimarySelection.
CTRL-SHIFT-{C,V} use Clipboard.
{SHIFT,CTRL}-Insert use PrimarySelection.
`CompleteSelection` and `CompleteSelectionOrOpenLinkAtMouseCursor` now
require a parameter to specify the destination clipboard.
Removed the `default_clipboard_XXX` options added in
8dad34fa61 in favor of just explicitly
assigning the key/mouse bindings.
closes: #417
* Adds `CopyTo` and `PasteFrom` assignments that specify the
destination/source.
* Adds `default_clipboard_copy_destination` and `default_paste_source`
config options that specify the default destination/source for
existing `Copy` and `Paste` operations (for @bew)
* Deprecating `PastePrimarySelection` in favor of `PasteFrom`.
* Added `CTRL-Insert` -> `Copy` (for @Babar)
Aside from the new key assignment, these changes shouldn't change
the default behavior, but do make it easier to consider changing
that in a later commit.
They should allow for example:
* Set `default_clipboard_copy_destination = "PrimarySelection"` to
prevent populating the clipboard by default when using the mouse.
* Overriding the CTRL-Insert, CTRL-SHIFT-C to explicitly populate
the clipboard
* Set `default_paste_source = "PrimarySelection"` for middle click
to paste the selection.
* Overriding SHIFT-Insert, CTRL-SHIFT-V to explicitly paste from
the clipboard.

* Add ClearBuffer action
Clears all lines, both visible and those scrolled off the top of the viewport, making the prompt line the new first line and resetting the scrollbar thumb to the full height of the window.
This is the behavior that Hyper / xterm has for clearing the terminal.
* Combine ClearBuffer into ClearScrollback as enum with associated erase mode
Makes it easier to manage the different options of clearing the terminal.
The default is true, which means that adjusting the font size will
cause the window to resize to preserve the number of rows/cols in
the terminal.
When set to false, the window size is preserved and the number of
terminal rows/cols is adjusted instead.

This appears to have been broken since the introduction of mouse
assignments :-/
This commit adds Pane::is_alt_screen_active so that the gui layer
can tell whether the alt screen is active, and allow passing down
the event.

Since we no longer have our fallback Software renderer (only mesa),
remove what has become an empty variant and hoist the GL state up
into RenderState, holding Option<RenderState> in the window.
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.

```
printf "\x1b[4m\x1b[58;2;255;0;0mred underline\x1b[0m"
```
prints "red underline" in the foreground color, with an
underline that is bright red `rgb(255, 0, 0)`.

These aren't currently rendered, but the parser and model now support
recognizing expanded underline sequences:
```
CSI 24 m -> No underline
CSI 4 m -> Single underline
CSI 21 m -> Double underline
CSI 60 m -> Curly underline
CSI 61 m -> Dotted underline
CSI 62 m -> Dashed underline
CSI 58 ; 2 ; R ; G ; B m -> set underline color to specified true color RGB
CSI 58 ; 5 ; I m -> set underline color to palette index I (0-255)
CSI 59 -> restore underline color to default
```
The Curly, Dotted and Dashed CSI codes are a wezterm assignment in the
SGR space. This is by no means official; I just picked some numbers
that were not used based on the xterm ctrl sequences.
The color assignment codes 58 and 59 are prior art from Kitty.

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.

This adopts a similar technique to that used to pass the wezterm
config to the term crate, but this time it is for passing it to
the window crate.
The use_ime option has been ported over to this new mechanism.
Hooks up toggling fullscreen mode on macos, with plumbing for
other systems.
I prefer not to use the "modern fullscreen" mode because I find
the transition animations in macOS are horrendously slow.
I'll make an option to allow selecting whether that is used or not
in a follow-on diff.

The new banner is less intrusive; it doesn't steal focus
and for users that have multiple wezterm processes, doesn't show
one per process.
So let's turn off the updater window. I'm considering moving the
"smart" upgrade links into a helper subcommand, but that's for
another diff.
This commit keeps the content from the last release check in a local
file and reads from that file on startup to set a two-line release
info banner in each new pane.
* 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
can be rendered via the termwiztermtab bits.
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.
