This offers a few additional hotkeys that can be used in combination
with scrollback. None of these are used by default yet.
This implements the following bindings:
- ScrollPageUp: Scroll exactly one screen height up
- ScrollPageDown: Scroll exactly one screen height down
- ScrollToTop: Scroll as far up as possible
- ScrollToBottom: Scroll as far down as possible
This fixes #1151.

When selecting to the top and starting in the first cell, alacritty
would crash. These cases have been fixed and now selection should be
completely working.

When scrolling down with a selection on screen the first line was not
properly selected. This has been fixed by making sure the selection
always starts in the first cell when it is only partially visible.

When the user selected multiple lines, dragging the selection downwards,
and then leaves the cursor to the left side of the first cell, the first
cell was still incorrectly selected. This has been fixed.
The selection also did not update if the mouse was outside of the
window, now all movement events are accpeted even when the mouse is
outside of the window. This allows updating the selection when the user
is dragging the cursor too far.
Mouse movement and click events outside of the window are not
propagated, these are only used for updating the selection.

There were a few issues with selection in scrollback that were mainly
off-by-one errors. This aims at fixing these issues.
This also fixes a bug that currently exists in master where the last
cell is not selected when the mouse leaves the window to the right.

Because there was some overlap with branch #1095, these two PRs have
been added together and the config has been restructured to make use of
a `scrolling` section.
The default faux scrolling amount has also been changed to `3` because
this simplifies the code and falls in line with what most other terminal
emulators do.
There should be no additional test failures due to this.

It is now possible to configure the amount of lines the viewport should
scroll when using the normal scrolling mode.

There was an issue where alacritty tries to convert the lines in a
selection to the on-screen lines even when the selection is not on the
screen. This results in a crash.
To prevent this from happening the selection now is not shown if it is
off the screen.
There currently still is a bug that when the selection is at the top of
the screen but still half visible, it will not show the top line as
selected but start in the second line.
This bug should be resolved with
https://github.com/jwilm/alacritty/pull/1171.
This fixes #1148.

To make it possible to access the native scrollback buffer in the
alternate screen without having to disable faux scrolling, faux
scrolling is now disabled when the `shift` key is held down.
This should allow alacritty to have the best of both worlds, a native
scrollback buffer in the alternate screen buffer and faux scrolling.

When implementing fallback to the default value with an u32 you will get
0 as the default value.
However the default scrollback value is 10_000. A custom deserializer
has been implemented which automatically falls back to the correct
default value.

Selections now *mostly* work. They move as the buffer scrolls, copying
works as it should, and it looks like the different selection modes
behave properly as well.
The new Selection implementation uses buffer coordinates instead of
screen coordinates. This leads to doing a transform from mouse input to
update the selection, and back to screen coordinates when displaying the
selection. Scrolling the selection is fast because the grid is already
operating in buffer coordinates.
There are several bugs to address:
* A _partially_ visible selection will lead to a crash since the drawing
routine converts selection coordinates to screen coordinates. The
solution will be to clip the coordinates at draw time.
* A selection scrolling off the buffer in either direction leads to
indexing out-of-bounds. The solution again is to clip, but this needs
to be done within Selection::rotate by passing a max limit. It may
also need a return type to indicate that the selection is no longer
visible and should be discarded.
* A selection scrolling out of a logical scrolling region is not
clipped. A temporary and robust workaround is to simply discard the
selection in the case of scrolling in a region.

Supporting selections with scrollback has two major components:
1. Grid needs access to Selection so that it may update the scroll
position as the terminal text changes.
2. Selection needs to be implemented in terms of buffer offsets -- NOT
lines -- and be updated when Storage is rotated.
This commit implements the first part.

Things that do not work
- Limiting how far back in the buffer it's possible to scroll
- Selections (need to transform to buffer offsets)

This intends to optimize the case where the top of the scrolling region
is the top of the screen. In theory, scrolling in this case can be
optimized to shifting the start/end of the visible region, and then
rearranging any lines that were not supposed to be scrolled (at the
bottom of the region). However, this didn't produce quite the speedup I
expected.

In addition to a marginal performance improvement, this simplifies some
logic in the Term implementation since now the Grid fully handles row
recycling.
|
| | | |
| | |
| | |
| | |
| | | |
The type selection::Region was defined identially to std::ops::Range.
Using something other than range just served to confuse.

This is part of some cleanup for the grid module as a whole.

VecDeque offers improved performance beyond a plain Vec for common
scrolling situations (full screen scroll). Additionally, VecDeque is
necessary for performant scrollback since recycling old rows for a Vec
would be expensive (push/pop front would shift entire vec).

Since `cargo-deb` has been updated on crates.io it is now
possible to just install it from crates.io and build Alacritty's
deb without having to rely on github.

There have been a number of issues an PRs opened since
the cargo-deb installation does not work with the latest
version from crates.io.
To help out users until the crates.io version is updated,
the installation instructions have been temporarily
changed to install `cargo-deb` through github.

The (e)print macro will panic when there is no output available to
write to, however in our scenario where we only log user errors to
stderr, the better choice would be to ignore when writing to stdout or
stderr is not possible.
This changes the (e)print macro to make use of `write` and ignore
any potential errors.
Since (e)println rely on (e)print, this also solves potential failuers
when calling (e)println.
With this change implemented, all of logging, (e)println and (e)print
should never fail even if the stdout/stderr is not available.

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).

Add optional color for the dim foreground (`\e[2m;`)
Defaults to 2/3 of the foreground color. (same as other colors).
If a bright color is dimmed, it's displayed as the normal color. The
exception for this is when the bright foreground is dimmed when no
bright foreground color is set. In that case it's treated as a normal
foreground color and dimmed to DimForeground.
To minimize the surprise for the user, the bright and dim colors have
been completely removed from the default configuration file.
Some documentation has also been added to make it clear to users what
these options can be used for.
This fixes #1448.
