This resolves various bugs related to vi-less search. The primary issue
was that when jumping between matches more than 1000 lines apart, the
search would get stuck and not advance between matches properly due to
the 1000 line synchronous search limit.
Some other issues related to the tracking of the search origin have also
been fixed, improving the viewport positioning while interacting with
the search outside of vi mode. This was done by keeping the search
origin outside of the viewport, which allows for search to start right
at the first character. Previously the search was on top of the first
character which lead to it being excluded from search.
Fixes#4626.
This adds a new visual indicator which shows the position in history of
either the display offset during search, or the vi mode cursor.
To make it as unintrusive as possible, the overlay is hidden whenever
the vi mode cursor collides with its position.
Fixes#3984.
This fixes up all of the remaining enums which are used in the
configuration file to make sure they all support fully case insensitive
deserialization.
Fixes#4611.
This reverts 1d00883 since it is not necessary anymore after all search
bindings are now proper key bindings. This fixes a bug which would cause
the first character to be swallowed when using IME after triggering any
key binding which doesn't send any `ReceivedCharacter` event.
Fixes#4588.
Alacritty's description in the readme and manpage has always been a bit
overly aggressive in its marketing. This new updated text should more
accurately describe Alacritty's current state without pointlessly
agitating people.
This commit makes cursors being drawn via rects, thus it's always above
underlines/strikeouts. Also, since the cursor isn't a glyph anymore, it
can't be obscured due to atlas switching while glyphs are rendered.
Fixes#4404.
Fixes#3471.
This patch prevents missing zerowidth glyphs from obscuring the rendered
glyph of a cell.
The missing glyph itself is also consistently loaded and displayed on
all platforms. It is initialized once together with the ascii symbols
and then written to the atlas only once for every cached missing glyph.

Commit 5725f58 introduced a performance regression on macOS due to
excessive calls to the `invalidateShadow` function, however calling this
function only on redraw after a resize was performed does not fix the
underlying problem.
As a solution, window shadows are now disabled completely for all
transparent windows. This makes sure there is no performance impact,
while still solving the problem with text artifacts on resize.
Fixes#4604.
Due to the way macOS draws shadows for transparent windows, resizing
them will lead to text artifacts remaining present after a window has
been resized.
The `invalidateShadow` call is used whenever the opacity isn't `1.0` to
make sure these shadows are cleared before redrawing, so no artifacts
remain when resizing transparent windows.
Fixes#889.
This replaces the existing `Deserialize` derive from serde with a
`ConfigDeserialize` derive. The goal of this new proc macro is to allow
a more error-friendly deserialization for the Alacritty configuration
file without having to manage a lot of boilerplate code inside the
configuration modules.
The first part of the derive macro is for struct deserialization. This
takes structs which have `Default` implemented and will only replace
fields which can be successfully deserialized. Otherwise the `log` crate
is used for printing errors. Since this deserialization takes the
default value from the struct instead of the value, it removes the
necessity for creating new types just to implement `Default` on them for
deserialization.
Additionally, the struct deserialization also checks for `Option` values
and makes sure that explicitly specifying `none` as text literal is
allowed for all options.
The other part of the derive macro is responsible for deserializing
enums. While only enums with Unit variants are supported, it will
automatically implement a deserializer for these enums which accepts any
form of capitalization.
Since this custom derive prevents us from using serde's attributes on
fields, some of the attributes have been reimplemented for
`ConfigDeserialize`. These include `#[config(flatten)]`,
`#[config(skip)]` and `#[config(alias = "alias)]`. The flatten attribute
is currently limited to at most one per struct.
Additionally the `#[config(deprecated = "optional message")]` attribute
allows easily defining uniform deprecation messages for fields on
structs.
Previously the _NET_WM_ICON would use the .ico which was also used for
the Windows icon. This icon used the dimensions 256x256, but the maximum
supported image size is 192x192, so a new image with the dimensions
64x64 has been added.
Since we know the image format anyways, the `image` dependency could
also be easily replaced with `png`, which cuts out a few extra unused
dependencies.
This adds a history to the regex search limited to at most 255 entries.
Whenever a search is either confirmed or cancelled, the last regex is
entered into the history and can be accessed when a new search is
started.
This should help users recover complicated search regexes after
accidentally discarding them, or handle repeated searches with the same
regexes.
Fixes#4095.
This strictens the ESC escape sequence parser to prevent invalid
intermediates from being ignored. Previously the parser would just look
at the first intermediate without validating that the rest of them is
empty.
If an escape like `\e(#0` is used now, it will no longer be accepted as
`\e(0` since the intermediate `#` is also present.
Since BSD does not support inotify polling in the `notify` crate and
instead relies on manual filesystem polling, this would cause a high CPU
usage at 100 polls a second.
A separate polling rate of once per second is now used for platforms
which do not support filesystem polling, allowing users to still make
use of live config reload on BSD.
Fixes#3871.
Since the current behavior would just load the default configuration
file whenever the configuration file couldn't be loaded, the path was
not set to any value. As a result however, the live config reload
feature would not work with a broken yaml (one which cannot be
deserialized, not one with warnings).
If a configuration file has been specified, but the deserialization
still failed, the path is now preserved on the default configuration
file to make it possible to live reload a fix for the issue.
Fixes#4561.
Previously Alacritty would not report cursor escapes to the application
when a mouse button was held down and the mouse was moved. This prevents
applications like tmux from updating their selection.
Similarly to how windowing libraries keep reporting mouse events when
the left mouse button is held down over the window, the escape sequences
are now clamped to within the grid and reported to applications.
Fixes#4566.
Since live-shader-reload is generally unused and unmaintained, and could
only be used for debugging purposes, since it refers relative paths,
this feature was removed for the sake of simplicity.
Currently Alacritty requires a separate `draw` call to OpenGL whenever a
new rectangle is rendered to the screen. With many rectangles visible,
this has a significant impact on rendering performance.
Instead of using separate draw calls, the new `RectRenderer` will build
a batch of rectangles for rendering. This makes sure that multiple
rectangles can be grouped together for single draw calls allowing a
reduced impact on rendering time.
Since this change is OpenGL 2 friendly, it should not make it more
complicated to transition away from the 3.3+ requirements like an
alternative instancing based implementation might have.
This resolves an issue with Alacritty's scrolling region performance
when there's a number of fixed lines at the top of the screen. This
affects commonly used applications like tmux or vim.
Instead of using separate logic for when the scrolling region starts at
the top of the screen without any fixed lines, the code should now try
to figure out the target position of these fixed lines ahead of time,
swap them into place and still perform the optimized implementation to
move the grid.
This comes with the small trade-off that since lines are swapped before
rotating the screen without clearing or removing any lines during the
rotation process, that the places the fixed lines have been swapped with
will appear out of order when using scrolling regions in the primary
screen buffer. Since the use of scrolling regions primarily affects the
alternate screen and most terminals don't keep any history at all, this
should however not cause any problems.
It seems like the list of colors might have changed a bit, leading to
indexed colors not being transformed into their dim colors correctly.
To prevent this from happening in the future, the dimming for colors in
the range '0..=7' is now performed by offsetting them from the
'NamedColor::DimBlack'. Since this is the first dimmed color, this
should always work as long as all dimmed colors are added in the correct
order.
This removes some of Alacritty's CLI flags since the same functionality
is provided by the '--option' flag now.
The removed flags are:
* '--persistent-logging'
* '--live-config-reload'
* '--no-live-config-reload'
* '--dimensions'
* '--position'
Fixes#4246.
The previous version would search for the last tag by matching the
beginning of the tag name. By explicitly searching for the trailing `"`
with grep, an exact tag match is now enforced.
Since releases like v1.2.3 always match the beginning of their RCs
(v1.2.3-rc4), this makes sure that the assets aren't pushed to the
previous release.
This adds support for blinking the terminal cursor. This can be
controlled either using the configuration file, or using escape
sequences.
The supported control sequences for changing the blinking state are
`CSI Ps SP q` and private mode 12.
This allows the configuration file imports to start with '~/' and
resolve relative to the user's home directory.
There is no support for '~user/' or '$HOME/' or any other shell
expansion. However since paths relative to the home directory should be
sufficient for everything, this provides a very simple solution without
any significant drawbacks.
Fixes#4157.
This patch makes sure that the message for the creation of a log file is
always the first entry, before any other log file messages.
Since we initialize our log file dynamically, the message is printed as
soon as something is written to it. By making sure that we always write
to a file first and then try stdout, we can ensure that the log file is
always initialized before ever writing log messages to stdout.
Since the vi mode is unrelated to the terminal emulation itself, it
should not be reset during a `reset` to prevent unnecessary confusion.
This also prevents the search from switching from vi mode to vi-less
search without any indication to the user.
By reducing the number of CI jobs for GitHub actions, it should be
possible to get a faster overview over the status of all CI jobs. While
this does increase the total build time of GitHub Actions by reducing
parallelization, it should still finish within the SourceHut CI times.
