Teach Alacritty to stop setting the window as urgent upon a bell by
emulating xterm's 'bellIsUrgent' resource and relevant CSI. When this
resource is enabled (with 'CSI ? 1042 h'), a bell event causes the
window to be marked as urgent. When the resource is disabled (with 'CSI
? 1042 l'), the window is not marked urgent in the event of a bell.
There are two wrinkles worth noting here:
- The 'TermMode::URGENCY_HINTS' does _not_ affect the terminal's
configured bell command, since we only want to control whether or
not the window is marked as urgent, not anything else.
- In xterm, the 'bellIsUrgent' resource is _disabled_ by default.
Since bouncing the dock icon has been the default in Alacritty on
macOS thus far, do not make an effort to change that in this patch.
This allows users to emit "\e[?1042l" and disable bouncing the dock
icon.
Fixes#2950.
Checking for target os in build.rs doesn't work, since build.rs
is running for host, so checking should be done in src. Thus moving
'compile_error!' check from build.rs to main.rs.
When formatting text for display in the message bar, Alacritty was using
the byte length of the text instead of the glyph count. This lead to
unnecessary blank space at the end of lines due to overestimation of
their length.
There also were no extra spaces inserted after fullwidth characters,
leading to Alacritty giving them only a single cell of space. In line
with the rest of Alacritty's rendering, a wide char spacer whitespace is
now inserted in the message bar after glyphs which should occupy two
cells.
Fixes#4250.

This changes the minimum terminal dimensions from 2 lines and 2 columns,
to 1 line and 2 columns.
This also reworks the `SizeInfo` to store the number of columns and
lines and consistently has only the terminal lines/columns stored,
instead of including the message bar and search in some places of the
Alacritty renderer/input.
These new changes also make it easy to properly start the selection
scrolling as soon as the mouse is over the message bar, instead of
waiting until it is beyond it.
Fixes#4207.

When doing selection expansion we were checking for wide char flags
on a cells from the bottom of the terminal instead of in a current
viewport when scrolled up in history, which was leading to expanding
more than needed if we had wide chars on the same viewport cell,
but in the bottom of the terminal.
Fixes#4257.
Since we only applied the CLI arguments as overrides to the
configuration file after the file was loaded, all CLI arguments that are
stored on the config would be dropped without a configuration file in
place.
This also makes sure that all configuration file config overrides are
still loaded if the configuration file could not be loaded for any
reason, since there's no reason why we'd just drop everything in that
case.
This updates the lockfile to the new format introduced in Rust 1.41.0.
Since the lockfile has been completely regenerated, all depedencies were
updated.
Since the `Term` implements the `Dimensions` trait itself, we shouldn't
call `term.grid()` to call methods from the `Dimensions` trait.
This removes all instances of this that I could find in the code at the
moment.
This uses the facilities added in
3c3e6870de to allow overriding individual
configuration file options dynamically from the CLI using the
--options/-o parameter.
Fixes#1258.
This adds the ability for users to have multiple configuration files
which all inherit from each other.
The order of imports is chronological, branching out to the deepest
children first and overriding every field with that of the configuration
files that are loaded at a later point in time.
Live config reload watches the directories of all configuration files,
allowing edits in any of them to update Alacritty immediately. While the
imports are live reloaded, a new configuration file watcher will only be
spawned once Alacritty is restarted.
Since this might cause loops which would be very difficult to detect, a
maximum depth is set to limit the recursion possible with nested
configuration files.
Fixes#779.
This resolves an issue with selection scrolling which would cause the
selection to wrap to the top of the screen once the cursor enters the
padding below the message bar.
Fixes#4120.
This commit completes the effort to use config colors for
message bar content by picking red/yellow from user's
colors.normal.{red,yellow} for error/warning messages
instead of fixed colors.
It also removes alacritty_terminal::term::color::RED and
alacritty_terminal::term::color::YELLOW from the alacritty_terminal API,
bumping its version to 0.11.0-dev.
Fixes#4116.
This adds support for double underlines using the colon separated escape
sequence `CSI 4 : 2 m`.
Alacritty will now also always fallback to the normal underline in case
any of the other underlines like the undercurl are specified. The escape
sequence `CSI 4 : 0 m` can now be used to clear all underlines.
Some terminals support `CSI 21 m` for double underline, but since
Alacritty already uses that as cancel bold which is a little more
consistent, that behavior has not changed. So the colon separated
variant must be used.
This resolves an issue where Alacritty would crash when a wrapline flag
was present in the last column of the last line.
While it should not be possible to achieve this with normal text flow,
it is possible to rotate the content downwards using the `CSI Ps T`
escape, causing this bug to occur.
This also works around other issues like the vi cursor jumping to the
top of the screen when trying to move beyond the last column using the
`l` key. In debug mode this even lead to a crash due to the overflow.
Fixes#4109.
Since users should be capable of finding packages for their
distributions, this removes all instructions that point users directly
at specific packages.
The third party repositories like COPR have been kept, since those
are more difficult to find.
The structure of the installation instructions has also been reworked to
adjust for this and the post build instructions should be a bit cleaner
now.

The InstanceData type in the rendering subsystem was previously 17 f32s
plus one u8 which occupied a total of 72 bytes per instance. This meant
that for every character or background cell drawn, 72 bytes were sent to
the GPU. In the case of a 400x100 cell grid, a total of 2.9MB would be
sent.
This patch reduces InstanceData's size to 36 bytes, a 50% improvement!
Using the above example for comparison, a worst case of 1.44MB would be
transferred.
The motivation for this patch comes from macOS. Once the terminal grid
would reach a certain size, performance experienced a sharp and dramatic
drop (render times would go from ~3ms to ~16ms). I don't want to
speculate too much on the underlying issue, but suffice it to say that
this patch alleviates the problem in my testing.
While the performance impact was most significant on macOS, with
rendering times cut by more than 50% in some cases, this also results in
a measurable performance difference on other systems with high density
grids.

This resolves an issue where negative window positions set in the
configuration file would not place the Alacritty window in the correct
location.
Fixes#4061.
