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.
|
|
Use a `map_or` instead of a `map().unwrap_or()` chain.
|
|
This commit adds support for hyperlink escape sequence
`OSC 8 ; params ; URI ST`. The configuration option responsible for
those is `hints.enabled.hyperlinks`.
Fixes #922.

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.

Previously Alacritty was using two different ways to reference lines in
the terminal. Either a `usize`, or a `Line(usize)`. These indexing
systems both served different purposes, but made it difficult to reason
about logic involving these systems because of its inconsistency.
To resolve this issue, a single new `Line(i32)` type has been
introduced. All existing references to lines and points now rely on
this definition of a line.
The indexing starts at the top of the terminal region with the line 0,
which matches the line 1 used by escape sequences. Each line in the
history becomes increasingly negative and the bottommost line is equal
to the number of visible lines minus one.
Having a system which goes into the negatives allows following the
escape sequence's indexing system closely, while at the same time making
it trivial to implement `Ord` for points.
The Alacritty UI crate is the only place which has a different indexing
system, since rendering and input puts the zero line at the top of the
viewport, rather than the top of the terminal region.
All instances which refer to a number of lines/columns instead of just a
single Line/Column have also been changed to use a `usize` instead. This
way a Line/Column will always refer to a specific place in the grid and
no confusion is created by having a count of lines as a possible index
into the grid storage.

This fixes up all of the remaining enums which are used in the
configuration file to make sure they all support fully case insensitive
deserialization.
Fixes #4611.

The zerowidth characters were conventionally stored in a [char; 5].
This creates problems both by limiting the maximum number of zerowidth
characters and by increasing the cell size beyond what is necessary even
when no zerowidth characters are used.
Instead of storing zerowidth characters as a slice, a new CellExtra
struct is introduced which can store arbitrary optional cell data that
is rarely required. Since this is stored behind an optional pointer
(Option<Box<CellExtra>>), the initialization and dropping in the case
of no extra data are extremely cheap and the size penalty to cells
without this extra data is limited to 8 instead of 20 bytes.
The most noticible difference with this PR should be a reduction in
memory size of up to at least 30% (1.06G -> 733M, 100k scrollback, 72
lines, 280 columns). Since the zerowidth characters are now stored
dynamically, the limit of 5 per cell is also no longer present.

This bug was caused by trying to grow the terminal while the cursor line
was wrapped but entirely empty. Resizing the terminal now accounts for
the position of the deleted line and moves the cursor up only when the
line deleted was above it.
The deletion of the line was caused by the shell redrawing itself
whenever the cursor is moved.
Fixes #3583.

Keeping the license as part of every file bloats up the files
unnecessarily and introduces an additional overhead to the creation of
new modules.
Since cargo already provides excellent dependency management, most of
the code-reuse of Alacritty should occur through Rust's dependency
management instead of copying it source.
If code is copied partially, copying the license from the main license
file should be just as easy as copying from the top of the file and
making some adjustments based on where it is used is likely necessary
anyways.

This commit aims to clear up the separation between Term and Grid to
make way for implementing search.
The `cursor` and `cursor_save` have been moved to the grid, since
they're always bound to their specific grid and this makes updating
easier.
Since the selection is independent of the active grid, it has been moved
to the `Term`.

This fixes a bug where a row would always get reset completely if its
background does not equal the default terminal background. This leads to
big performance bottlenecks when running commands like `echo "\e[41m" &&
yes`.
Instead of resetting the entire row whenever the template cell is not
empty, the template cell is now compared to the last cell in the row.
The last cell will always be equal to the previous template cell when
`row.occ < row.inner.len()` and if `occ` is equal to the row's length,
the entire row is always reset anyways.
Fixes #2989.

Previously Alacritty would delete lines when clearing the screen, leading to a
loss of data in the scrollback buffer. Instead of deleting these lines, they
are now rotated outside of the visible region.
This also fixes some issues with Alacritty only resetting lines partially when
the background color of the template cell changed.
Fixes #2199.

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.
Fixes #2796.
Fixes #2694.
Fixes #2643.
Fixes #2625.
Fixes #2618.
Fixes #2601.

Fixes #2334.
Fixes #2254.
Fixes #2217.
Fixes #1789.
Fixes #1750.
Fixes #1125.

Since ref tests were only stored whenever winit requested the window
close, they would not get stored properly when the terminal was closed
through Alacritty using `exit`, Ctrl+D or similar.
This moves the ref test code to the and of the main entry point, which
will always be executed regardless of how the terminal was shutdown.
Fixes #2613.

This resolves an issue with rows only resetting partially, based on
their `occ` state. However this state is not always accurate, so more
than just the occupied elements need to be cleared.
Fixes #2340.
|
|
The crate containing the entry point is called alacritty, and the crate
containing everything else is called alacritty_terminal.
