- The <Hyper> key now sends <C-M-S-Insert> to make keybinding
easier.
- the <Ctrl> key with a multibyte character now prepends
<C-M-S-Insert>
- <Shift-Space> now returns the "\x1b[32;2u"
- <Shift-Alt> now sends ""\x1b\x1b[32;2u""

Traditionally only ASCII characters can be sent with the ALT key. This
is an arbitrary restriction than I have relaxed. This means now ALT+ñ
will produce '^[ñ' on the terminal as expected.
I have also added support for the Windows key to send the escapesequence
'\x1b@\x1b\' so a mapping can be created in Vim for something like
'<M-@><M-\>t' for Windows+t.
In addition, it's worth noting that Glutin does not differentiate
between the windows key and the hyper key, so if one is relatively
perverse like me and has a hyper key, it can be used to sent logo keys
to the terminal without X intercepting it.

This PR combines a couple of optimizations to drastically reduce the
time it takes to gather everything necessary for rendering Alacritty's
terminal grid.
To help with the iteration over the grid, the `DisplayIter` which made
heavy use of dynamic dispatch has been replaced with a simple addition
to the `GridIterator` which also had the benefit of making the code a
little easier to understand.
The hints/search check for each cell was always performing an array
lookup before figuring out that the cell is not part of a hint or
search. Since the general case is that the cell is neither part of hints
or search, they've been wrapped in an `Option` to make verifying their
activity a simple `is_some()` check.
For some reason the compiler was also struggling with the `cursor`
method of the `RenderableContent`. Since the iterator is explicitly
drained, the performance took a hit of multiple milliseconds for a
single branch. Our implementation does never reach the case where
draining the iterator would be necessary, so this sanity check has just
been replaced with a `debug_assert`.
Overall this has managed to reduce the time it takes to collect all
renderable content from ~7-8ms in my large grid test to just ~3-4ms.

This resolves an issue where an excessive clipboard update frequency
would cause the Wayland display server to ignore necessary selection
updates.
Instead of copying the selection to the clipboard during the selection
process, it is now only copied once the mouse button is released.

The patch 9cb5562 has introduced a regression which would abort if a
mouse report's line was bigger than zero, which is the exact opposite of
when a mouse report is required.

This resolves an issue with Alacritty crashing after a resize, due to
the last cached mouse point being out of bounds.
Instead of caching the mouse point, it is now computed on demand to make
sure it can never be invalid.

This adds some built-in actions for handling hint selections without
having to spawn external applications.
The new actions are `Copy`, `Select` and `Paste`.

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 adds support for hints, which allow opening parts of the visual
buffer with external programs if they match a certain regex.
This is done using a visual overlay triggered on a specified key
binding, which then instructs the user which keys they need to press to
pass the text to the application.
In the future it should be possible to supply some built-in actions for
Copy/Pasting the action and using this to launch text when clicking on
it with the mouse. But the current implementation should already be
useful as-is.
Fixes #2792.
Fixes #2536.

This refactors a large chunk of the alacritty_terminal API to expose all
data necessary for rendering uniformly through the `renderable_content`
call. This also no longer transforms the cells for rendering by a GUI
but instead just reports the content from a terminal emulation
perspective. The transformation into renderable cells is now done inside
the alacritty crate.
Since the terminal itself only ever needs to know about modified color
RGB values, the configuration for colors was moved to the alacritty UI
code.

This reverts 1d00883 since it is not necessary anymore after all search
bindings are now proper key bindings. This fixes a bug which would cause
the first character to be swallowed when using IME after triggering any
key binding which doesn't send any `ReceivedCharacter` event.

This commit makes cursors being drawn via rects, thus it's always above
underlines/strikeouts. Also, since the cursor isn't a glyph anymore, it
can't be obscured due to atlas switching while glyphs are rendered.

This replaces the existing `Deserialize` derive from serde with a
`ConfigDeserialize` derive. The goal of this new proc macro is to allow
a more error-friendly deserialization for the Alacritty configuration
file without having to manage a lot of boilerplate code inside the
configuration modules.
The first part of the derive macro is for struct deserialization. This
takes structs which have `Default` implemented and will only replace
fields which can be successfully deserialized. Otherwise the `log` crate
is used for printing errors. Since this deserialization takes the
default value from the struct instead of the value, it removes the
necessity for creating new types just to implement `Default` on them for
deserialization.
Additionally, the struct deserialization also checks for `Option` values
and makes sure that explicitly specifying `none` as text literal is
allowed for all options.
The other part of the derive macro is responsible for deserializing
enums. While only enums with Unit variants are supported, it will
automatically implement a deserializer for these enums which accepts any
form of capitalization.
Since this custom derive prevents us from using serde's attributes on
fields, some of the attributes have been reimplemented for
`ConfigDeserialize`. These include `#[config(flatten)]`,
`#[config(skip)]` and `#[config(alias = "alias)]`. The flatten attribute
is currently limited to at most one per struct.
Additionally the `#[config(deprecated = "optional message")]` attribute
allows easily defining uniform deprecation messages for fields on
structs.

This adds a history to the regex search limited to at most 255 entries.
Whenever a search is either confirmed or cancelled, the last regex is
entered into the history and can be accessed when a new search is
started.
This should help users recover complicated search regexes after
accidentally discarding them, or handle repeated searches with the same
regexes.
Fixes #4095.

Previously Alacritty would not report cursor escapes to the application
when a mouse button was held down and the mouse was moved. This prevents
applications like tmux from updating their selection.
Similarly to how windowing libraries keep reporting mouse events when
the left mouse button is held down over the window, the escape sequences
are now clamped to within the grid and reported to applications.
Fixes #4566.

This adds support for blinking the terminal cursor. This can be
controlled either using the configuration file, or using escape
sequences.
The supported control sequences for changing the blinking state are
`CSI Ps SP q` and private mode 12.

This removes the restriction of not being able to select text while the
search is active, making it a bit less jarring of a UX when the user
tries to interact with the terminal during search.
Since the selection was used during vi-less search to highlight the
focused match, there is now an option for a focused match color, which
uses the inverted normal match color by default. This focused match is
used for both search modes.
Other mouse interactions are now also possible during search, like
opening URLs or clicking inside of mouse mode applications.

This changes the minimum terminal dimensions from 2 lines and 2 columns,
to 1 line and 2 columns.
This also reworks the `SizeInfo` to store the number of columns and
lines and consistently has only the terminal lines/columns stored,
instead of including the message bar and search in some places of the
Alacritty renderer/input.
These new changes also make it easy to properly start the selection
scrolling as soon as the mouse is over the message bar, instead of
waiting until it is beyond it.
Fixes #4207.

Since the `Term` implements the `Dimensions` trait itself, we shouldn't

This implements search without vi mode by using the selection to track
the active search match and advancing it on user input. The keys to go
to the next or previous match are not configurable and are bound to
enter and shift enter based on Firefox's behavior.

Previously the SearchEndNext and SearchEndPrevious match acted exactly
like the SearchNext and SearchPrevious action, however this is not how
vim works. In vim, regardless of direction the `gN` action always jumps
to the next match start to the left of the cursor, while the `gn` action
always jumps to the next search end to the right of the cursor.
While both approaches might seem reasonable at first, vim's approach has
a significant advantage w.r.t. predictability and automation of the
movement. By always knowing which direction the motion goes to, this
allows for mappings that reliably navigate inside the current match
regardless of the global search direction. So deleting until the end of
the match would always be `dgn` for example, regardless in which
direction the user has jumped to it.
Fixes #3953.

This commit removes font dependency from alacritty_terminal,

This adds a new regex search which allows searching the entire
scrollback and jumping between matches using the vi mode.
All visible matches should be highlighted unless their lines are
excessively long. This should help with performance since highlighting
is done during render time.

While the commit 43c0ad6ea9d2467ccf867a310c4f1e30f5b627c6 introduced
right click as a way to expand the active selection, it did not allow
for holding right click to continuously do so.
This commit remedies that problem by allowing live expansion with while
holding the right mouse button.

This adds a new `Scheduler` which allows for staging events to be
processed at a later time.
If there is a selection active and the mouse is above or below the
window, the viewport will now scroll torwards the direction of the
mouse. The amount of lines scrolled depends on the distance of the mouse
to the boundaries used for selection scrolling.
To make it possible to scroll while in fullscreen, the selection
scrolling area includes the padding of the window and is at least 5
pixels high in case there is not enough padding present.

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`.
