Still a WIP because of unimplemented Linux portion.
Support has been added for font rasterization options. At this time, the
only supported option is antialias. It's a tri-state flag which can be
either ~ for "use default", true to force antialias, and false to force
disable antialias.
The options may be specified both globally and per font section. The per
font sections override global options. An example of a complex config
follows. In the example, the global value requests using default
antialias settings, and the normal face disables antialias.
font:
options:
antialias: ~
normal:
family: monospace
options:
antialias: false
Finally, note that the top level font.options is used for fallback
fonts.

It seems that (as a rule) terminal emulators use the text mouse cursor rather
than the pointer that is used now. This commit changes the cursor to
using winit's built-in configuration function.

Adds a call to action on how to improve Wayland support in Alacritty.

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.

Since landing the patch adding transparency support to Alacritty,
there's been an issue where othewise solid background cells were also
being rendered partially transparent. Now, all filled background cells
are rendered fully opaque.
Some logic was added to support discarding filled backgrounds which had
the same color as the default background. This means that, if the
default background is #000 and a cell has that background, it will never
be rendered opaque. This may not be correct.
Note that many truecolor vim color schemes print spaces for default
colored background cells. Performance can be dramatically improved by
using ctermbg=NONE guibg=NONE to skip rendering those cells.

Also rearranged the default config slightly to move the long key binding
list to the bottom of the file.

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.

Must have been broken when upgrading notify-rs
|
|
This shouldn't have any effect, but at least the default value is now
consistent with the default deserialization value.

* Use correct keyname for decreasing font size in MacOS
* Prefer Command instead of Control to match other TEs

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 }

Should prevent the messed up background colors that appear in some
situations (especially on tiling WMs).

Fixes naming collision issue on Fedora 26.

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.
|
|
To allow FontConfig to work with Bitmap font, we shall pass the size
we are interested in, and account for the size returned in the font
matching process. This is, because we cannot scale those fonts.
FontConfig will return the closest match, and we take its returned
pixel size back when we are rendering the glyphs.
There's an oddity when call set_char_size in TrueType - we need to
behave as if the DPI is 72. It is due to the following macro:
#define FT_REQUEST_HEIGHT( req ) \
( (req)->vertResolution \
? ( (req)->height * (FT_Pos)(req)->vertResolution + 36 ) / 72 \
: (req)->height )
Further work can allow for integer scaling of the largest bitmap
font variant.
Tested with Terminus PCF-type font under Linux.
This addresses issue #582 .

When RUST_LOG environment variable is set, uses env_logger instead of
our custom logger. This is desirable for debugging purposes.
|
|
The FreeType rasterizer now reads settings like antialias, rgba,
lcdfilter, and hintstyle and chooses FreeType settings accordingly. The
result is that Alacritty fonts should look similar to the rest of the
system.
|
|
The hash map of key -> face was previouly cloned every time a glyph was
rasterized. This refactored the rasterization path to be more borrowck
friendly.
Sadly, this implementation is not *that* clean, but once NLLs land, much
of this can be cleaned up.

The fontconfig `FcPattern` type is wrapped as `fc::Pattern` and
`fc::Pattern` ref. All methods for accessing data on the pattern now
return an `Iterator`. This API turns out to be much more ergonomic than
providing an integer index. We also override the default `nth`
implementation of `Iterator` on these accessors to allow random
(incremental only) access.
For instance, accessing `family` attributes from a pattern:
let families = pattern.family();
let second = pattern.nth(1);
Or printing available styles
for style in pattern.style() {
println!("style={}", style);
}
|
|
Each Fc type is split into a separate file. This organization will help
as features are added to the bindings.

Removed freetype2-devel, it isn't necessary given fontconfig-devel depends on freetype2-devel, just as it depends on expat-devel.

This reverts commit e17d38167e174a2cf664e430fe968ec6492e1f08.

This PR fixes a few wayland issues of alacritty (and updates glutin on
the process because it is needed).
Mainly two changes are done:
1. Add a drawing_ready() method on Window: see
https://docs.rs/winit/0.8.2/winit/os/unix/trait.WindowExt.html#tymethod.is_ready
for explanations. Hopefully glutin will be able to handle it itself in
the future, but it currently does not.
2. resize window and OpenGL contextes.
The way wayland forces winit to draw its own decorations and how surface
size is defined by its content means that in practice:
- winit's window.set_inner_size() defines the dimensions of the
borders
- glutins gl_window.resize() defines the dimensions of the content
(and is a noop in other platforms)
It is for now glutin's user responsibility to keep them in sync
otherwise borders are drawn stupidly. This PR changes the resize methods
of alacritty::Window to always update both.
This fixed the borders issues for me, tested on weston.

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.

The previous format of --live-config-reload=VAL had a specific set of
allowed values which may not immediately be obvious. Instead, there are
now two flags which control the behavior:
--live-config-reload
--no-live-config-reload
If a user tries to specify both, the option parsing will fail with this
message:
error: The argument '--no-live-config-reload' cannot be used with
'--live-config-reload'
|
|
This will keep the original behavior for users who don't update their
config.
|
|
Provide a command line option as well as a configuration file option.
The command line option takes precedence.
