This adds the option to specify the color of the visual bell using the
`visual_bell.color` configuration setting.
This is done by rendering a big quad over the entire screen, which also
opens up options to draw other arbitrary rectangles on the screen in the
future.
This resolves issues with copy-pasting tabs by including them in the
pasted string.
Selection of tabs is still inconsistent with what might be expected
based on other terminal emulators, however the behavior hasn't
regressed.
This fixes https://github.com/jwilm/alacritty/issues/219.
Certain programs like `htop` have problems with the number
of color pairs which are specified by the Alacritty terminfo
file.
By reducing the maximum number of color pairs to the value
which is specified by xterm-256color, these issues are
resolved.
This fixes#1862.
Instead of rendering zero-width characters as full characters, they are
now properly rendered without advancing the cursor.
Because of performance limitations, this implementation only supports up
to 5 zero-width characters per cell. However, as a result of this
limitation there should not be any performance impact.
This fixes#1317, fixes#696 and closes#1318.
Since running `clear` inside of tmux doesn't actually clear any part of
the screen, but just resets the scrolling region, the warning and error
notices can't be removed without quitting tmux or Alacritty.
As a solution, a new action `ClearLogNotice` has been added which has
been bound to Ctrl+L by default. As a result, Ctrl+L can be used inside
of tmux to remove the messages, even though tmux doesn't clear the
screen.
This fixes#1811.
To make sure that all error and information reporting to the user is
unified, all instances of `print!`, `eprint!`, `println!` and
`eprintln!` have been removed and replaced by logging.
When `RUST_LOG` is not specified, the default Alacritty logger now also
prints to both the stderr and a log file. The log file is only created
when a message is written to it and its name is printed to stdout the
first time it is used.
Whenever a warning or an error has been written to the log file/stderr,
a message is now displayed in Alacritty which points to the log file
where the full error is documented.
The message is cleared whenever the screen is cleared using either the
`clear` command or the `Ctrl+L` key binding.
To make sure that log files created by root don't prevent normal users
from interacting with them, the Alacritty log file is `/tmp/Alacritty-$PID.log`.
Since it's still possible that the log file can't be created, the UI
error/warning message now informs the user if the message was only
written to stderr. The reason why it couldn't be created is then printed
to stderr.
To make sure the deletion of the log file at runtime doesn't create any
issues, the file is re-created if a write is attempted without the file
being present.
To help with debugging Alacritty issues, a timestamp and the error
level are printed in all log messages.
All log messages now follow this format:
[YYYY-MM-DD HH:MM] [LEVEL] Message
Since it's not unusual to spawn a lot of different terminal emulators
without restarting, Alacritty can create a ton of different log files.
To combat this problem, logfiles are removed by default after
Alacritty has been closed. If the user wants to persist the log of a
single session, the `--persistent_logging` option can be used. For
persisting all log files, the `persistent_logging` option can be set in
the configuration file
This adds the `window.dynamic_padding` option which allows disabling the
dynamic spread of additional padding around the grid's content.
Based on the feedback I've gotten so far and the fact that most other
terminal emulators do not seem to center the content inside themselves,
I've changed the default configuration option to disable centering of the grid.
This fixes#1778.
Since the version 0.2.2 had some significant breakage which affects a
large number of users, this 0.2.3 release aims at providing a stable
release which works for everyone without any major regressions.
The extra window padding was calculated in the renderer which lead to
problems with the paddings calculated in the `src/display.rs` and
`src/term/mod.rs`.
As a solution, every instance of `config.padding().x/y` has been removed
from the renderer (`src/renderer/mod.rs`), instead the padding is always
passed through from the `src/display.rs`.
The initial calculations during display creation and after resize then
are scaled appropriately and then the extra padding is calculated. As a
result every other location can just make use of the correctly
calculated `size_info.padding_x` and `size_info.padding_y`.
The documentation has been changed to clearly state that the padding is
scaled by DPI now.
This fixes#1773.
Currently alacritty always puts the grid at the top-left position of the
window. The only distance to the top-left window border is set by the
padding in the config.
However the grid always has a fixed size, and if a cell doesn't
completely fit the screen anymore, the padding at the bottom right
window corner can be significantly bigger than the padding at the top
left.
To fix this whenever there is more space left and there would usually be
a bigger padding at the bottom right, the space is now split up and
added to the padding.
This should always center the grid inside the window and make sure all
borders have the same padding from the text area.
This screenshot shows how it has been until now:
Here is how it looks now:
This fixes#1065.
The environment variables specified in the configuration file are now
all set before the window is created. As a result, this makes it
possible to add the `WINIT_HIDPI_FACTOR` env variable directly to the
Alacritty configuration.
This fixes https://github.com/jwilm/alacritty/issues/1768.
Some changes include:
• Use the with_hardware_acceleration function on the ContextBuilder to not require the discrete GPU
• Remove the LMenu and RMenu virtual key codes (winit 0.16.0 removed these because Windows now generates LAlt and RAlt instead
• Replace set_cursor_state with hide_cursor (winit 0.16.0 removed the set_cursor_state function)
• Replace GlWindow::hidpi_factor with GlWindow::get_hidpi_factor and change to expecting an f64
• Use the glutin/winit dpi size and position types where possible
Glutin's dpi change event has been implemented. All size events now
return logical sizes. As a result of that, the logical sizes are translated
in the `display::handle_rezize` method so DPI scaling works correctly.
When the DPI is changed, the glyph cache is updated to make use of the
correct font size again.
Moving a window to a different screen which is a different DPI caused a
racing condition where the logical size of the event was sent to the
`handle_resize` method in `src/display.rs`, however if there was a DPI
change event before `handle_resize` is able to process this message, it
would incorrectly use the new DPI to scale the resize event.
To solve this issue instead of sending the logical size to the
`handle_resize` method and then converting it to a physical size in
there, the `LogicalSize` of the resize event is transformed into a
`PhysicalSize` as soon as it's received. This fixes potential racing
conditions since all events are processed in order.
The padding has been changed so it's also scaled by DPR.
The `scale_with_dpi` config option has been removed. If it's not present
a warning will be emitted.
The `winit` dependency on Windows has been removed. All interactions
with winit in Alacritty are handled through glutin.
This release introduces some config to automatically build deploy a
binaries on the github release page using travis. The build only happens
when a commit is tagged and it uses the stable version of rust.
The main travis sections (install/script/before_deploy) have been
moved out of the .travis.yml to make it easier to read, maintain and
extend the different steps of the CI process.
Since checking for the Rust version in CI is enough to know if clippy
should be used or not, the environment variable `CLIPPY` has also been
removed, which further allowed simplifying the CI process.
Besides the executables, some auxillary files are now also published as
part of a release when they have changed since the last tagged Alacritty
release. This should make it clear for returning users when a new
version of a specific auxillary file is required.
Instead of using the 14.04 image which travis provides by default, an
18.04 docker image is used to build the output binaries for Linux.
This affects both the .deb and the .tar.gz binary.
The advantage of this is that while binaries compiled on 14.04, do not
work on 18.04, it does work the other way around. The generated .tar.gz
binary has been tested on 18.04, Debian, Fedora and Archlinux and all
systems were able to run it without any warnings or errors.
Properly update an active selection while scrolling the main scrollback buffer.
This does not affect the alternate screen buffer, since no scrollback buffer is
available.
It is now possible to paste in mouse mode again by making use of the
`shift` key while pressing the mouse button reserved for PasteSelection.
All mouse bindings are now also matching the modifiers in a relaxed way,
so extra modifiers are ignored.
There are a couple of cursor-related options in the Alacritty config
file now, however they aren't grouped together in any way.
To resolve this a new `cursor` field has been added where all cursor
configuration options (besides colors) have been moved.
The `custom_cursor_colors` option has also been removed, since it's not
necessary anymore. Simply making the `colors.cursor.*` fields optional,
allows overriding the cursor colors whenever one of them is present.
Like that the user doesn't have to think about a relation between two
separate configuration options.
This PR initially put the `hide_cursor_when_typing` variable under
`cursor.hide_when_typing`. However this field is completely unrelated to
the cursor, but instead relates to the mouse cursor.
Since the word `cursor` is already used for the active cell in the grid
of a terminal emulator, all occurences of the word `cursor` when talking
about the mouse have been replaced with the word `mouse`.
The configuration option has also been moved to
`mouse.hide_when_typing`, to make it clear what this option is changing.
This fixes#1080.
This adds the option to automatically launch URLs with a specified
program when clicking on them.
The config option `mouse.url_launcher` has been added to specify which
program should be used to open the URL. The URL is always passed as the
last parameter to the specified command.
It is not always desired for URLs to open automatically when clicking on
them. To resolve this a new `modifiers` field has been introduced to the
config, which allows specifying which keyboard modifiers need to be held
down to launch URLs in the specified launcher.
Some tests have been added to make sure that the edge-cases of the URL
parsing are protected against future regressions. To make testing easier
the parsing method has been moved into the `SemanticSearch` trait. The
name of the trait has also been changed to just `Search` and it has been
moved to `src/term/mod.rs` to fit the additional functionality.
This fixes#113.
Whenever the viewport is scrolled, the selection is rotated to make sure
that it moves with the viewport. However this did not correctly handle
the underflow that happens when the selection goes below 0.
This resolves that problem for the selection by moving the internal line
representation to an isize, thus correctly keeping track of the
selection start/end points even when they have a negative index. Once
the selection is converted to a span, the lines are clamped to the
visible region.
This fixes#1640 and fixes#1643.
This change should allow the usage of scancodes in the configuration
file.
When a VirtualKeyCode for glutin is not present, this should now allow
the user to use the scancodes instead. If the user specifiecs a key with
its scancode even though the key has a VirtualKeyCode, it should still
work.
The behavior of directly specifying a VirtualKeyCode should be unchanged
by this.
This fixes#1265.
Initial support for Windows is implemented using the winpty translation
layer. Clipboard support for Windows is provided through the `clipboard`
crate, and font rasterization is provided by RustType.
The tty.rs file has been split into OS-specific files to separate
standard pty handling from the winpty implementation.
Several binary components are fetched via build script on windows
including libclang and winpty. These could be integrated more directly
in the future either by building those dependencies as part of the
Alacritty build process or by leveraging git lfs to store the artifacts.
Fixes#28.
The terminal lock is now dropped before rendering by storing
all grid cells before clearing the screen.
This frees the terminal to do other things since the lock is now
free, which lead to a performance benefit with high throughput
applications.
When rendering selections with both start and end outside of the visible
area, Alacritty would assume that both start and end are either above or
below the viewport and not render the selection at all.
To fix this the `buffer_line_to_visible` method now returns a
`ViewportPosition` instead of an `Option<Line>`, this allows giving more
feedback about where outside of the visible region the line is using the
`ViewportPosition::Above` and `ViewportPosition::Below` variants.
Using these newly introduced variants, a selection spanning the whole
screen is now rendered if the selection should go from above the visible
area to below it.
This fixes#1557.
Since the mouse start position has been the first movement event after
the mouse button was held down, there have been some issues with the
start point lagging behind the cursor because movement events were not
reported from the initial position but there was a gap until movement
starts reporting.
To fix this whenever the mouse button is pressed, the position and cell
side is stored on the `Mouse` struct. Because of this it does not matter
anymore if the movement events are all reported and we can just start a
selection using the stored position/side whenever there currently is no
selection present.
This fixes#1366
When selecting multiple lines in Alacritty, there was an issue with
empty lines not being copied. This behavior has been chanaged so empty
lines should be correctly copied now.
When copying content which ends with an empty line, Alacritty would copy
an additional empty line.
This has been resolved by only adding empty lines when the empty line
was not in the last selected line.
This replaces the current definitions, which depend on the system's
'xterm-256color' terminfo definition with the `alacritty` and
`alacritty-direct` definitions.
The new definitions are completely standalone.
The default `TERM` value has been changed to be dynamically
set based on the definitions installed on the system. Alacritty will
try to use the `alacritty` definition first and fall back to
`xterm-256color` if the `alacritty` definition is not present.
Previously Alacritty has initialized all lines in the buffer as soon as
it is started. This had the effect that terminals which aren't making
use of the scrollback buffer yet, would still consume large amounts of
memory, potentially even freezing the system at startup.
To resolve this problem, the grid is now dynamically resized in chunks
of `1000` rows. The initial size is just the visible area itself, then
every time lines are written to the terminal emulator, the grid storage
is grown when required.
With the worst-case scenario of having 100_000 lines scrollback
configured, this change improves startup performance at the cost of
scrolling performance.
On my machine the startup changes from ~0.3 to ~0.2 seconds.
The scrolling performance with large throughput is not affected, however
it is slowed down when the number of lines scrolled are close to the
100_000 configured as scrollback. The most taxing benchmark I've found
for this was running `yes | dd count=500 > 500.txt` (note the relatively
small file size). This will cause a slowdown on the first run from 0.05s
to 0.15s. While this is significant, it lines up with the time saved at
startup.
This fixes#1236.
A new configuration option `save_to_clipboard` has been added
to the `selection` section of the configuration. This allows writing
every selection to the primary system clipboard when it is set
to `true`.
On linux the selection is still written to the selection clipboard,
independent of the value of the `save_to_clipboard` setting.
This adds a config option which allows setting terminal colors above the
0..16 range.
Live config reload already works for this, so it is possible to change
these colors the same way it works with the normal colors.
If a color below 16 is specified, the configuration will throw an error,
so the normal colors can't be overridden. This is just to prevent
possible complications with the settings that already exist.
The mesa workaround has lead to some issues with
rendering on Wayland.
To resolve this problem, the mesa workaround has been
restructured in a way which still allows clearing the screen
before rendering without killing performance with the mesa
driver. The performance is identical to the master brach
and there have been no recorded regressions.
