The previous behavior was to always treat ctrl-alt as altgr on Windows,
this has been done to better support altgr through a VNC session,
but this is very unintuitive when you don't need this behavior.

I'm calling it a temporary defeat on the shaping changes;
this commit effectively reverts the series of changes made
to support slicing up ligatures like `->` when the cursor
moves through them.
They've introduced so many issues and I've spent hours
that haven't resulted in a complete solution, so I've
disabled those changes by putting them behind a boolean
option.
I'll revisit them after I've cut the next release.

Queries the system battery information and returns an array of
battery information.
Each element is a lua table with the following entries:
* state_of_charge: expressed as percents
* vendor: the battery manufacturer
* model: the battery model
* serial: the battery serial number
* time_to_full: how long until the battery is full
* time_to_empty: how long until the battery is empty
* state: "Charging", "Discharging", "Empty", "Full", "Unknown"
I haven't run this on a system with a battery yet, so I'm holding
off from showing an example until I've got a work one.

As explained in the docs included in this commit, ideally this
wouldn't be needed, but due to a long-standing hinting bug in
freetype <https://gitlab.freedesktop.org/freetype/freetype/-/issues/761>
it seems most expedient to just render our own block glyphs,
so that's what this does!

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.

In the earlier times wezterm supported different font rasterizers,
and the configuration was a bit vague and generic to accomodate
differences in how the rasterizers worked.
Since then, we've standardized on freetype.
One of the things that's been bothering me for a while is that
we have some fiddly logic to transform from the config to the freetype
flags.
This commit does away with the transformation and simply exposes
the two sets of freetype options.
The main thing that I expect people to play with is
`freetype_load_target` which can have one of the following values:
```
pub enum FreeTypeLoadTarget {
/// This corresponds to the default hinting algorithm, optimized
for standard gray-level rendering.
Normal,
/// A lighter hinting algorithm for non-monochrome modes. Many
generated glyphs are more fuzzy but better resemble its original
shape. A bit like rendering on Mac OS X. This target implies
FT_LOAD_FORCE_AUTOHINT.
Light,
/// Strong hinting algorithm that should only be used for
monochrome output. The result is probably unpleasant if the glyph
is rendered in non-monochrome modes.
Mono,
/// A variant of Normal optimized for horizontally decimated LCD displays.
HorizontalLcd,
/// A variant of Normal optimized for vertically decimated LCD displays.
VerticalLcd,
}
```
I expect most people will want to set this to one of `Normal`, `Light`
or `HorizontalLcd`. `HorizontalLcd` is what `font_antialias=Subpixel`
used to select.

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.

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`.

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.

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.
61c52af491 accidentally broke key
assignments that included ALT on macOS (and perhaps others?) because
LEFT_ALT or RIGHT_ALT were also now being passed through to the
keymap lookup, preventing a direct match.
This defaults to None, taking the default from the freetype library.
You can select an integer value to tell the library to use an
alternative version.
Versions that are available in the build used by wezterm are 35, 38 and
40.
See https://freetype.org/freetype2/docs/subpixel-hinting.html for
more information.
The default is 1.0. `line_height` is used to scale the effective
cell height, increasing the amount of space between font baselines.

This helps keep the config object a bit smaller and the trace logging
output less verbose.
We now memoize the effective palette in the config, which should shave
off a little bit of time in the renderer.
in ab342d9c46 I started to rearrange how
the output processing thread works. It wasn't quite right, so this
commit tidies things up.
The main change here is that there is now back-pressure from the output
parser on the reader; if it is taking a while to parse the output then
we don't buffer up so much input.
This makes operations like `find /` followed immediately by `CTRL-C`
more responsive.
With this change, I don't feel that the
`ratelimit_output_bytes_per_second` option is needed any more, so it
has been removed.
To avoid confusing behavior, normalize the configured keys
in the same way that we normalize key presses.
In other words, this:
```lua
{
key = "y",
mods = "CTRL|SHIFT",
action = "Copy",
}
```
is treated as if you wrote:
```lua
{
key = "Y",
mods = "CTRL",
action = "Copy",
}
```

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.

Adds an option to control how wide glyphs (more specifically: square
aspect glyphs) are scaled to conform to their specified width.
The three options are `Never`, `Always`, and `WhenFollowedBySpace`.
When a glyph is loaded, if it is approximately square, this option is
consulted. If overflow is permitted then the glyph will be scaled
to fit only the height of the cell, rather than ensuring that it fits
in both the height and width of the cell.

Bundle the *Last Resort High-Efficiency* font from

version 13.001 (Oct 22 2020).
This provides a more useful fallback glyph than we'd otherwise
produce if there is no matching glyph in any of the fonts.
Its license is OFL-1.1 which is compatible with the other
bundled fonts.
There are a number of cases where font-loader might panic on windows,
and the optional font-loader dep causes problems with `cargo vendor`
in #337, so this is a step to removing that dep.
This commit makes direct GDI calls to enumerate monospace truetype
fonts from the system and then applies our normal matching on the
result.
This makes it possible to configure wezterm to eg: triple click
on command input (or output) to select the entire input or output
without messing around trying to find the bounds.
The docs have an example of how to configure this; it requires
setting up shell integration to define the appropriate semantic
zones.
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 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 revises the opacity configuration to make it more
consistently applied.
* `window_background_opacity` controls the overall window capacity,
whether a background image is present or not.
* When a background image is present, or if the window is transparent,
then text whose background color is the default background is
changed to have a fully transparent background.
* `text_background_opacity` controls the alpha channel value for
text whose background color is NOT the default background.
It defaults to 1.0 (fully opaque), but can be set to be
transparent by setting it to a number between 0.0 and 1.0.
* The inactive pane hue, saturation, brightness multipliers
have been factored out into their own struct which changes
that set of options to:
```lua
return {
inactive_pane_hsb = {
hue = 1.0,
saturation = 1.0,
brightness = 1.0,
},
}
```
* `window_background_image_hsb` is a new option that can apply
a hue, saturation, brightness transformation to a background
image. This is primarily useful to make a background image
darker:
```lua
return {
window_background_image = "/some/pic.png",
window_background_image_hsb = {
brightness = 0.3,
},
}
```

Upcoming changes to the GUI mean that it will be double
the work to keep maintaining this, and it is already lagging
behind on pane support.
With the Mesa llvmpipe fallback we should be in a pretty
good state to not need another non-GL implementation.
I thought it would be cute to add an option to add a background image to
the window.
While playing around with the parameters, I accidentally implemented
window transparency on X11/Wayland, provided that you have a compositing
window manager. I don't know of the transparency also works on macOS or
Windows as of yet; will try that out once I push this commit.
This commit introduces three new configuration options explained below.
In the future I'd like to allow specifying equivalent settings in a
color scheme, and then that would allow setting per-pane background
images.
```lua
return {
--[[
Specifies the path to a background image attachment file.
The file can be any image format that the rust `image`
crate is able to identify and load.
A window background image is rendered into the background
of the window before any other content.
The image will be scaled to fit the window.
If the path is not absolute, then it will taken as being
relative to the directory containing wezterm.lua.
]]
window_background_image = "/some/file",
--[[ Specifies the alpha value to use when rendering the background
of the window. The background is taken either from the
window_background_image, or if there is none, the background
color of the cell in the current position.
The default is 1.0 which is 100% opaque. Setting it to a number
between 0.0 and 1.0 will allow for the screen behind the window
to "shine through" to varying degrees.
This only works on systems with a compositing window manager.
Setting opacity to a value other than 1.0 can impact render
performance.
]]
window_background_opacity = 1.0,
--[[
Specifies the alpha value to use when applying the default
background color in a cell. This is useful to apply a kind
of "tint" to the background image if either window_background_image
or window_background_opacity are in used.
It can be a number between 0.0 and 1.0.
The default is 0.0
Larger numbers increase the amount of the color scheme's
background color that is applied over the background image.
This can be useful to increase effective contrast for text
that is rendered over the top.
]]
window_background_tint = 0.0,
}

This is similar in spirit to the work in 4d71a7913a
but for Windows.
This commit adds ANGLE binaries built from
07ea804e62
to the repo. The build and packaging will copy those into the same
directory as wezterm.exe so that they can be resolved at runtime.
By default, `prefer_egl = true`, which will cause the window
crate to first try to load an EGL implementation. If that fails,
or if `prefer_egl = false`, then the window crate will perform
the usual WGL initialization.
The practical effect of this change is that Direct3D11 is used for the
underlying render, which avoids problematic OpenGL drivers and means
that the process can survive graphics drivers being updated.
It may also increase the chances that the GPU will really be used
in an RDP session rather than the pessimised use of the software
renderer.
The one downside that I've noticed is that the resize behavior feels a
little janky in comparison to WGL (frames can render with mismatched
surface/window sizes which makes the window contents feel like they're
zooming/rippling slightly as the window is live resized). I think this
is specific to the ANGLE D3D implementation as EGL on other platforms
feels more solid.
I'm a little on the fence about making this the default; I think
it makes sense to prefer something that won't quit unexpectedly
while a software update is in progress, so that's a strong plus
in favor of EGL as the default, but I'm not sure how much the
resize wobble is going to set people off.
If you prefer WGL and are fine with the risk of a drive update
killing wezterm, then you can set this in your config:
```lua
return {
prefer_egl = false,
}
```

This changes the ALT/dead key behavior a little bit more,
and in a way that is likely more useful to terminal users.
The default behavior is that system dead key processing is enabled.
For example, with DEU keyboard layout activated:
* `^` `<SPACE>` results in a single `^`
* `^` `e` result in those two characters combining into an e with a
diacritic.
If the config sets `use_dead_keys = false` then the behavior changes;
wezterm probes the active keymap to determine which keys are marked
as dead keys and computes their single character expansion. When
the dead key is pressed then that expansion is substituted instead.
So `^` is simply `^`.
In order to pull this off, the window layer needs to selectively
call `TranslateMessage` for the system dead key expansion case
instead of unconditionally in the global message loop.
As a result of *that*, it means that we don't perform the default ALT
key translation for every key press any more. I looked to see how old
friend putty handles this and found that it only allows default system
processing for ALT-space and ALT-F4. I was resistent to selectively
processing system shortcuts because the full set are effectively
unknowable to an application and I didn't want to try to replicate
a wide selection of varying keypresses. I'm fine to only allow
these two, so this commit does that, and reverts the portion of
the prior commit that prevented passing general ALT key combinations
through.

This commit adds very basic first passes at representing the Pane
and GuiWindow types in lua script.
The `open-uri` event from 9397f2a2db
has been redefined to receive `(window, pane, uri)` parameters
instead of its prior very basic `uri` parameter.
A new key assignment `wezterm.action{EmitEvent="event-name"}` is
now available that allows a key binding assignment to emit an arbitrary
event, which in turn allows for triggering an arbitrary lua callback
in response to a key or mouse click.
`EmitEvent` passes the `(window, pane)` from the triggering window and
pane as parameters.
Here's a brief example:
```lua
local wezterm = require 'wezterm';
wezterm.on("my-thingy", function(window, pane)
local dims = pane:get_dimensions();
wezterm.log_error("did my thingy with window " .. window:window_id() ..
" pane " .. pane:pane_id() .. " " .. dims.cols .. "x" .. dims.viewport_rows);
window:perform_action("IncreaseFontSize", pane);
end)
return {
keys = {
{key="E", mods="CTRL", action=wezterm.action{EmitEvent="my-thingy"}},
}
}
```

This builds on the new lua event handler plumbing added
in ccea650a93 to co-opt
the default URI opening action:

wezterm.on("open-uri", function(uri)
if uri:find("jira") then
wezterm.log_error("do something with jira")
wezterm.run_child_process({
"wezterm",
"start",
"--",
"jira",
"view",
extract_task_from_uri(uri)
})
-- prevent the default action from opening in a browser
return false
else
-- log but allow the uri to be opened in the browser
wezterm.log_error("clicken " .. uri)
end
end)

`emit` is capable of being called by async code.
These functions are available to the config layer, but nothing in

Windows, so unconditionally try to remove the socket before binding,
otherwise the bind will falsely fail, claiming that another process
is already bound.
The docs for mux will need to be updated to show how to revise them
for the new mux server invocation:
```lua
unix_domains = {
{
name = "wsl",
serve_command = {"wsl", "wezterm-mux-server", "--daemonize"}
},
}
```
kindof a lot going on in this commit, unintentionally:
* Need the lua context set to be moved into the config crate
otherwise configs cannot be parsed by the server and we end
up with the default configs
* Make the server use smol for async io
* Drop the use of the daemonize crate, which I had forked anyway.
Just inline our own tighter daemonize module
* Improve daemon spawning synchronization, however, it still needs
work for windows to avoid blocking forever where we don't do
daemonizing.
