Fixes #2098.

This prevents cell_width or cell_height being zero.
Fixes #1693

The warning and error messages now don't overwrite other terminal
content anymore but instead resize the terminal to make sure that text
can always be read.
Instead of just showing that there is a new error and pointing to the log,
errors will now be displayed fully in multiple lines of text, assuming that
there is enough space left in the terminal.
Explicit mouse click handling has also been added to the message bar,
which made it possible to add a simple `close` button in the form of
`[X]`.
Alacritty's log file location is now stored in the `$ALACRITTY_LOG`
environment variable which the shell inherits automatically.
Previously there were some issues with the log file only being deleted
when certain methods for closing Alacritty were used (like typing
`exit`). This has been reworked and now Ctrl+D, exit and signals should
all work properly.
Before the config is reloaded, all current messages are now dropped.
This should help with multiple terminals all getting clogged up at the
same time when the config is broken.
When one message is removed, all other duplicate messages are
automatically removed too.

Since the IME was positioned using physical coordinates,
the location would be incorrect with monitors using a DPR
other than 1.0.
This has been resolved by converting the physical position
to a logical position using the methods built into winit.
Fixes #2056.
|
|
The general style for errors, warnings and info messages is to start
with a capitalized letter and end without a period. The main exception
is when dealing with nouns that are clearer with special case handling,
e.g. "macOS failed to work" or "ioctl is borked".
|
|
This makes use of the new rectangle rendering methods used to display
the colored visual bell to add proper underline and strikeout support to
Alacritty.
|
|
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 a lot of NLL issues, however full NLL will be necessary to
handle a couple of remaining issues.

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

There were some minor rounding issues in the padding codepath without
dynamic padding. These have been fixed, which should resolve issues with
blurry fonts on monitors with a fractional DPR.
This fixes https://github.com/jwilm/alacritty/issues/1806.
|
|
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.
|
|
The logic during the initial spawning of the window was a bit twisted
up. This has been resolved and it should all work properly now, even
without a resize event at startup.
This fixes #1781.
|
|
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.

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.
|
|
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.
|
|
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.
|
|
There were some unneeded codeblocks and TODO/XXX comments in the code
that have been removed. All issues marked with TODO/XXX have either been
already resolved or tracking issues exist.

Supporting selections with scrollback has two major components:
1. Grid needs access to Selection so that it may update the scroll
position as the terminal text changes.
2. Selection needs to be implemented in terms of buffer offsets -- NOT
lines -- and be updated when Storage is rotated.
This commit implements the first part.
|
|
Note that `WM_CLASS` is now set to `"alacritty", "Alacritty"`
instead of the previous value of `"Alacritty", "Alacritty"`. This
seems to be more standard.
This also contains some revised recommendations for installing the
`.desktop` file.
|
|
|
|
Prevent the cell dimensions from going below 1, this bug resulted in
allocation of large amounts of memory in the scrollback PR but is also
present on master.
Currently the approach is to just `panic!`, however an `eprintln!` and
`exit` could be an alternative too. I don't think it's realistic to
check this at startup and it should have no performance impact since the
failing method is only called once at startup.
To make it a bit more clear what kind of values are accepted, the
datatypes of offsets and paddings have also been changed so that these
don't accept floats anymore and padding can never be negative.
This should allow us to be a bit more strict with the config to make
sure that errors are printed when invalid values are specified (like
negative padding).
This fixes #1167.

Unwrapping inside the config file parsing can lead to some issues that
prevent us from falling back to a default configuration file.
One instance of that issue was mentioned in #1135.
Now all instances of `unwrap()` have been removed and replaced with
proper error handling. This will make the config more robust and
prevents live reload from silently breaking while alacritty is running.
This also fixes a few currently existing clippy issues.
Clippy added an additonal lint which complains about `MyStruct { field:
field }`.
These issues have been fixed, except for some false-positives and issues
in external macros which will probably be fixed with future updates (rust-lang-nursery/bitflags#149)
|
|
This commit adds clippy as a required step of the build process. To make
this possible, all existing clippy issues have been resolved.
|
|
This replaces the `font_size_modifier` stored on the `Term` struct with a `font_size` field.
With this change it is not necessary anymore to calculate the new font size from a delta but the current font size is always stored directly on the `Term` struct.
As a result of this it is now possible to increase the font size by more than 127 steps at runtime. It also limits the minimum font size to 1, so issues with the `font_size_modifier` dropping far below font size 1 are resolved with this change.
This fixes #955.

Some terminals have functionality around changing the type of mouse
cursor dynamically (arrow and text) based on which mode(s) the VTE is
in. For example, gnome-terminal changes the cursor from text (default)
to an arrow when opening programs that track mouse events (e.g. vim,
emacs, tmux, htop, etc.). The programs all allow using the mouse
interactively under some circumstances (like executing `set mouse=a` in
vim).
The programs that use an interactive mouse set the terminal mode to
different values. Though they're not entirely the same terminal mode
across programs, an emulator like vte (the library gnome-terminal
implements), changes the mouse cursor if the mouse mode is one of the
following:
- 1000: Mouse Click Tracking
- 1001: Mouse Highlight Tracking
- 1002: Mouse Cell Motion Tracking
- 1003: Mouse All Motion Tracking
- 1004: Mouse Focus Tracking
See https://github.com/GNOME/vte/blob/6acfa59dfcceef65c1f7e3570db37ab245f049c4/src/vteseq.cc#L708
for more information.
This commit adds functionality that changes the winit/glutin
`MouseCursor` when a mouse-listening mode of 1000-1004 is set. It
behaves similarly to when the window title changes.

Move/rename borderless into window_config as decorations

Until winit gives us more capabilities in regard to window decorations
this implements a simple switch that renders the window without any
title bar or border

Sets the urgent WM flag when bell is emitted on X11 systems.
Additionally, the flag is cleared on focus because not all WMs clear it
automatically.

Parts of neighboring glyphs in the atlas were being rendered
incorrectly. The issue is resolved by aligning cells to the pixel grid.
This behavior was achieved previously by first applying integer
truncation before casting to a float.
Fixes #844.
|
|
The source of the leak was loading up multiple copies of the FT_face
even when not necessary. Fonts are now appropriately cached for
FreeType when going through the `Rasterize::load_font` API.
Additionally, textures in the glyph cache are now reused.
The result of this is that resizing to already loaded fonts is free
from a memory consumption perspective.
|
|
Adds support for font resizing at run-time. Three new actions are
introduced:
* IncreaseFontSize - Increases current font size by 1.0
* DecreaseFontSize - Decreases current font size by 1.0
* ResetFontSize - Resets font size to that specified in the
configuration.
The stock config files have example configuration for each which should
match gnome-terminal. For convenience, the config entries are:
- { key: Key0, mods: Control, action: ResetFontSize }
- { key: Equals, mods: Control, action: IncreaseFontSize }
- { key: Subtract, mods: Control, action: DecreaseFontSize }
|
|
Rather than use DPI from config, use device-pixel-ratio from winit. This
is computed using the display DPI anyhow, so it should have the same
effect.
|
|
Because there are so many clippy warnings in the current codebase,
this commit removes '#![cfg_attr(feature = "clippy", deny(clippy))]',
to make it easier to fix warnings incrementally.

* Update to latest Glutin/winit
This *finally* gets us off the fork of Glutin we've been on for so long
and will unblock a number of other items. Functionality should be the
same as before.
The update forced our hand on a compiler update. It's no longer
feasible to pin on an old version. From now on, we require latest
stable.
