The intent is that when set, it changes defaults to something
more suitable for distributions.
I've also added a readme for distro maintainers.

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This allows moving past a number of outdated deps, but importantly,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.
Avoid using serde for mapping between Lua and Rust for the `Config`
struct.
This improves the build speed of the config crate by 2x; it goes down
from 30 seconds to 9 seconds on my 5950x.
Go directly to the underlying env_logger crate, as pretty_env_logger
hasn't been updated in some time, and I'd like to be able to redirect
the log output to a file more directly, and that feature is in a newer
version of the env logger than pretty_env_logger was pulling in.
This helper extracts the concrete set of hosts and their configurations
from the ssh config, and arranges to reload the wezterm config if they
are changed.
This is useful when constructing ssh domain configs.

This commit allows the following configuration:
```
wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }'
```
which sets the selection_bg to fully transparent, and selection_bg to
50% transparent gray.
When selection_fg is fully transparent we'll use the normal fg color.
When selection_bg is partially (or fully!) transparent, it will be
alpha blended over the current cell background color.
To support this, the config file will now accept rgba colors specified
as 4 whitespace delimited numeric values. If a value ends with `%` it
is interpreted as a number in the range 0-100. Otherwise, it is
interpreted as a number in the range 0-255. The 4 values are
red, green, blue, alpha.
At this time, only the selection_fg and selection_bg settings accept
alpha values.

This commit refines bidi property handling:
* experimental_bidi has been split into two new configuration settings;
`bidi_enabled` (which controls whether the terminal performs implicit
bidi processing) and `bidi_direction` which specifies the base
direction and whether auto detection is enabled.
* The `Line` type can now store those bidi properties (they are actually
split across 3 bits representing enabled, auto-detection and
direction)
* The terminal now has a concept of active bidi properties and default
bidi properties
* The default properties are pulled from the wezterm configuration
* active bidi properties are potentially set via escape sequences,
BDSM (which sets bidi_enabled) and SCP (which sets bidi_direction).
We don't support the 2501 temporary dec private mode suggested by
the BIDI recommendation doc at this time.
* When creating new `Line`'s or clearing from the start of a `Line`, the
effective bidi properties are computed (from the active props,
falling back to default propr) and applied to the `Line`.
* When rendering the line, we now look at its bidi properties instead
of just the global config.
The default bidi properties are `bidi_enabled: false` and
`bidi_direction: LeftToRight` which corresponds to the typical
bidi-unaware mode of most terminals.
It is possible to live reload the config to change the effective
defaults, but note that they apply, by design, to new lines being
processed through the terminal. That means existing output is
left unaffected by a config reload, but subsequently printed lines
will respect it. Pressing CTRL-L or otherwise contriving to have
the running application refresh its display should cause the
refreshed display to update and apply the new bidi mode.

`ScrollByPage` can accept non-integer values in the configuration.
This allows fractional page scrolling, such as by half a page.
The default remains the same, at 1 page.
Add `get_foreground_process_name` to both Pane and the lua wrapper.
Add `foreground_process_name` and `current_working_dir` fields to
`PaneInformation`. In order for those to be dynamically fetched,
switch the lua conversion for `PaneInformation` to be a UserData
with field access methods. It's a little more verbose but allows
us to lazily compute these two new fields.

This commit expands quick select mode so that you can trigger it
with distinct sets of patterns (eg: urls on one key assignment,
hashes on a different key assignment), different alphabets,
and lastly, the option to perform a different action from
the default copy action.
You can pair this with `action_callback` to run lua code to
do something with the selected text.
This commit also adds `wezterm.open_with`, a helper function
for opening documents/URLs.

CI got broken by the termwiz release. This commit teaches the
various `git describe --tags` calls to filter to the wezterm
tags which all start with the year. We're match `20*` which should
be good for the next 79 years.
I've removed the vergen dependency as there was no way to teach it
to do the equivalent matching, and it wasn't a terrible burden
to just inline the git describe call anyway.
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.

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
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.

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`.
refs: #416
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 builds on the new lua event handler plumbing added
in ccea650a93 to co-opt
the default URI opening action:
```lua
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)
```
This doesn't allow exactly the sketched out option from
issue #223 to be implemented, but may be close enough
to be useful.

* `wezterm.on("event-name", func)`
* `wezterm.emit("event-name", "arg1", "arg2")`
`on` allows registering multiple functions.
`emit` will call each of the registered functions in turn, passing
a copy of the arguments. If a handler returns false, no additional
handlers are called and `emit` will return false. Otherwise,
once all the handlers have been called, `emit` will return true.
`emit` is capable of being called by async code.
These functions are available to the config layer, but nothing in
wezterm uses them at this time.

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.
