Fixes #153.
|
|
This takes the latest glutin master to port Alacritty to the EventLoop
2.0 rework.
This changes a big part of the event loop handling by pushing the event
loop in a separate thread from the renderer and running both in
parallel.

This commit makes alacritty use Menlo as a fallback font on macOS if the config specified font family isn't found.
|
|
This fixes a recent regression in
cfc20d4f34dca535654cc32df18e785296af4cc5 which broke cursor colors when
specified in the `colors.cursor` field in the config.
It also removes a lot of unneeded code from the font crate related to
the cursor rendering.
This fixes #2338.
|
|
By setting the minimum Rust version and enforcing it with CI, Alacritty
should hopefully make it possible for maintainers to package the
application even on distributions which are not rolling release.
The 1.31.0 target has been chosen here because it's the first version of
the Rust 2018 release. Bumping this version in the future should be
considered to be a breaking change and should only be done with caution
and in consideration of the supported Rust versions of the major
distributions available.
This fixes #2277.
|
|
This reverts the removal of the call to libc::daemon and instead adds an
annotation to ignore the deprecation warnings on macos.
This will not be an issue in the future since macOS is only discouraging
the use of `daemon`, but I'm not aware of any intention to actually
remove it.
This fixes #2211.

|
|
|
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".
|

Since bitmap fonts do not provide their own underline metrics, the
self-calculated metrics which have been used for rusttype are now also
used for bitmap fonts with freetype.
The rusttype and bitmap fallback metrics have incorrectly offset the
underline by the underline height. Since the position is already defined
as the center point, that is not necessary.
All rounding and clamping has also been removed from the font library,
so that the raw values are reported now. The clamping and rounding is
now done in the line renderer.
|
|
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.

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 core-* dependencies have been updated and every breaking
change has been resolved.
These are the main changes which required adaption:
- font_path() returns a PathBuf now
- get_descriptors() returns an Option<CFArray>
- get_advances_for_glyphs and get_glyphs_for_characters are now unsafe.
All packages which did not have breaking updates have also been updated.

This fixes some existing clippy issues and runs the `font` tests through travis.
Testing of copypasta crate was omitted due to problens when running on headless travis-ci environment (x11 clipboard would fail).
|
|
|
|
Using clippy as a library has been deprecated, instead the `cargo
clippy` command should be used instead. To comply with this change
clippy has been removed from the `Cargo.toml` and is now installed with
cargo when building in CI.
This has also lead to a few new clippy issues to show up, this includes
everything in the `font` subdirectory. This has been fixed and `font`
should now be covered by clippy CI too.
This also upgrades all dependencies, as a result this fixes #1341 and
this fixes #1344.

fixes #1086

This cleans up a bunch of code.
|
|
The ascent calculation on darwin was more complicated than it needed to
be. By running a `.ceil()` instead of adding one, checking if it's 0,
substracting if it is, and then flooring it, a few instructions could be
shaved off.
|
|
|
|
As requested a few comments have been added to the darwin code. There
also was an off by one error in the ascent calculation which has been
corrected.
The beam cursor width has also been tweaked to be slightly slimmer in
general.
All code added in this PR has also been run through the default rustfmt
to make sure the formatting is okay.
|
|
The macos target now also supports the custom beam and underline
cursors. The only thing left for this is now is testing and making sure
it works with tiny fonts.
|
|
|
|
|
|
The cascade list is now generated from Menlo for all fonts. This doesn't
feel correct to me, but it seems to give the expected behavior on macOS.
One of the problems cited was that certain glyphs like ❯ would not be
rendered with default cascade lists for some fonts.
|
|
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.
|
|
|
|
Previously, the fallback symbol font copied the style of the font from
the config. However, the only available style for the fallback symbol
font is Normal slant, Normal weight.

Descent was being reported as a positive value instead of negative. This
caused the background and text alignment to be off dramatically.
Resolves #545
|
|
We previously had a hard-coded value for aligning glyphs within cells.
The font descent is now used, and the offset should be correct by
default.
|
|
The changes to metric consumption rendered the size argument
unnecessary, remove it.

Makes thin stroke rendering for darwin configurable by a new toplevel
key under `font:` in the config file. Defaults to false, has no impact
on non macos.
|
|
This work started because we wanted to be able to simply say "monospace"
on Linux and have it give us some sort of font. The config format for
fonts changed to accomodate this new paradigm. As a result, italic and
bold can have different families from the normal (roman) face.
The fontconfig based font resolution probably works a lot better than
the CoreText version at this point. With CoreText, we simply iterate
over fonts and check it they match the requested properties. What's
worse is that the CoreText version requires a valid family. With
fontconfig, it will just provide the closest matching thing and use it
(unless a specific style is requested).
|
|
This allows consumers of the font crate to handle errors instead of the
library panicking.

Ref tests use a recording of the terminal protocol and a serialization
of the grid state to check that the parsing and action handling systems
produce the correct result. Ref tests may be recorded by running
alacritty with `--ref-test` and closing the terminal by using the window
"X" button. At that point, the recording is fully written to disk, and a
serialization of important state is recorded. Those files should be
moved to an appropriate folder in the `tests/ref/` tree, and the
`ref_test!` macro invocation should be updated accordingly.
A couple of changes were necessary to make this work:
* Ref tests shouldn't create a pty; the pty was refactored out of the
`Term` type.
* Repeatable lines/cols were needed; on startup, the terminal is resized
* by default to 80x24 though that may be changed by passing
`--dimensions w h`.
* Calculating window size based on desired rows/columns and font metrics
required making load_font callable multiple times.
* Refactor types into library crate so they may be imported in an
integration test.
* A whole bunch of types needed symmetric serialization and
deserialization. Mostly this was just adding derives, but the custom
deserialization of Rgb had to change to a deserialize_with function.
This initially adds one ref test as a sanity check, and more will be
added in subsequent commits. This initial ref tests just starts the
terminal and runs `ll`.

This patch adds support for rendering italic fonts and bold fonts.
The `font` crate has a couple of new paradigms to support this: font
keys and glyph keys. `FontKey` is a lightweight (4 byte) identifier for
a font loaded out of the rasterizer. This replaces `FontDesc` for
rasterizing glyphs from a loaded font. `FontDesc` had the problem that
it contained two strings, and the glyph cache needs to store a copy of
the font key for every loaded glyph. `GlyphKey` is now passed to the
glyph rasterization method instead of a simple `char`. `GlyphKey`
contains information including font, size, and the character.
The rasterizer APIs do not define what happens when loading the same
font from a `FontDesc` more than once. It is assumed that the
application will track the resulting `FontKey` instead of asking the
font to be loaded multiple times.
|
|
This enables narrower rendering of glyphs and it tends to look a bit
better. iTerm2 and Terminal both do this.
|
|
|
|
|
|
This adds a bunch of APIs to CGContext (and supporting types) that
aren't actually necessary to turn on subpixel rendering. The key for
subpixel rendering were the options passed to bitmap_context_create().
Specifically, kCGImageAlphaPremultipliedFirst | kCGBitmapByteOrder32Host
are necessary to enable it.
