Fix incorrect usage of the `flags` when drawing the preedit resulting
in setting the `flags`, but not actually reading the value back.
The logic to skip things was also used incorrectly, because the renderer
does that already based on the `WIDE_CHAR` flag on the cell.

There's no need to force alacritty's user configuration on
other users of the crate, thus provide the options actually used
by alacritty_terminal itself.

After evaluation of the ahash with the data alacritty uses it was
discovered that it's 1.5-2x times faster when getting the already
hashed values, which is the primary cases for alacritty's renderer.
Given that ahash is generally faster, all the HashSet and HashMap's
inside the alacritty were changed to use it as a hasher function.

While we skip the spacers for the wide characters in the grid due to
them having a proper flags, the draw_string method was generating the
cells with incorrect flags leading to wide chars being cut off.

This should help trouble shooting the renderer being created and
different renderer options to determine when something like dual-source

The glutin 0.30.0 update decouples glutin from winit which
provides us with basis for a multithreaded renderer. This
also improves robustness of our configuration picking,
context creation, and surface handling.
As an example we're now able to start on systems without a vsync,
we don't try to build lots of contexts to check if some config works,
and so on.
That also brings us possibility to handle context losses, but that's
a future work.
Fixes #1268.

Similar to the underline line rendered when the cursor is over an hyperlink, for
graphics we now render a border around the graphic.

When text is added to a cell with a reference to a graphic, an operation is sent
to the OpenGL thread to replace a subregion of the cell with a transparent area.
If the OpenGL driver supports the GL_ARB_clear_texture extension, the region is
updated with glClearTexSubImage. If the extension is not available, the
texture is updated with glTexSubImage2D.

The merge requires multiple changes in order to be compatible with the last
version of Alacritty:
- Textures are now always deleted on Drop.
This is required because Alacritty now supports multiple windows in the same
process, so we can't assume that all resources are freed when a single window
is closed. This is the same approach used for the atlas textures.
- The graphics feature is only compatible with OpenGL 3.3.
Alacritty now supports GLES 2.2, but in order to provide a proper support for
it we need a different approach, specific for that version.
- Cell dimensions in pixels are re-added to the alacritty_terminal crate.

`OSC 8 ; params ; URI ST`. The configuration option responsible for

GLES2 has GL_EXT_blend_func_extended extension that enables
dual-source blending, so essentially we can reuse fragment shader
from GLSL3 renderer and do 1 rendering pass instead of 3 for the
text.

The `SizeInfo` is a SizeInfo used for rendering, which contains
information about padding, and such, however all the terminal need is
number of visible lines and columns.

This commit adds support for colored underline and refines the dynamic
extra storage. The extra storage now is using `Arc` making cloning it way
faster compared to `Box` approach which scales really well when it comes
to cloning in `Term::write_at_cursor`, since cloning `Arc` is constant
time.
Fixes #4142.

Currently Alacritty only works on hardware which supports OpenGL 3.3 or
more, which can become problematic with older devices. This patch adds a
new GLES2 renderer, since it is much more widely supported, especially
on weaker hardware like phones or a Raspberry Pi.
While the GLES2 renderer is slower than the OpenGL 3.3+ version, it is
still significantly faster than software rendering. However because of
this performance difference it is only used when necessary and there
should be no difference for machines supporting OpenGL 3.3+.
The two renderers are largely independent and separated in the
`renderer/text/glsl3` and `renderer/text/gles2` modules. Separate
shaders are also required for text rendering. The rectangle rendering
for underlines and the visual bell works identically for both versions,
but does have some version-specific shader code.
Fixes #128.

This commit finishes the effort from a64553b to avoid reloading font
twice during startup, since the original issue is with getting font
metrics without building the glyph cache.
|
| | |
| |
| |
| |
| |
| |
| | |
Instead of creating a `Rasterizer` to guess the window dimensions,
dropping it and then creating a new one for the glyph cache, reuse the
same `Rasterizer`.
This prevents the font from being loaded twice during startup.

This commit adds hand rolled drawing of unicode box drawing[1] and
block elements[2] from ranges U+2500 up to U+259f. While using system
font for such characters will look better most of the time, the
characters tend to overlap or not align, so providing builtin font is
the lesser evil here.

Alacritty's `msg create-window` subcommand would previously inherit all
the CLI parameters from the original executable. However not only could
this lead to unexpected behavior, it also prevents multi-window users
from making use of parameters like `-e`, `--working-directory`, or
`--hold`.
This is solved by adding a JSON-based message format to the IPC socket
messages which instructs the Alacritty server on which CLI parameters
should be used to create the new window.

Previously Alacritty would always initialize only a single terminal
emulator window feeding into the winit event loop, however some
platforms like macOS expect all windows to be spawned by the same
process and this "daemon-mode" can also come with the advantage of
increased memory efficiency.
The event loop has been restructured to handle all window-specific
events only by the event processing context with the associated window
id. This makes it possible to add new terminal windows at any time using
the WindowContext::new function call.
Some preliminary tests have shown that for empty terminals, this reduces
the cost of additional terminal emulators from ~100M to ~6M. However at
this point the robustness of the daemon against issues with individual
terminals has not been refined, making the reliability of this system
questionable.
New windows can be created either by using the new `CreateNewWindow`
action, or with the `alacritty msg create-window` subcommand. The
subcommand sends a message to an IPC socket which Alacritty listens on,
its location can be found in the `ALACRITTY_SOCKET` environment
variable.
Fixes #607.

In this change I went through all current rustfmt configuration options
and expanded our existing configuration with overrides whenever deemed
appropriate.
The `normalize_doc_attributes` option is still unstable, but seems to
work without any issues. Even when passing macros like `include_str!`
that is recognized properly and not normalized. So while this wasn't an
issue anywhere in the code, it should make sure it never will be.
When it comes to imports there are two new major additions. The
`imports_granularity` and `group_imports` options. Both mostly just
incorporate unwritten rules that have existed in Alacritty for a long
time. Unfortunately since `alacritty_terminal` imports in `alacritty`
are supposed to be separate blocks, the `group_imports` option cannot be
used.

In some cases it could be desired to apply 'background_opacity'
to all background colors instead of just 'colors.primary.background',
thus adding an 'colors.opaque_background_colors' option to control that.
Fixes #741.
