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`.
The env logger has been broken for over a year and is not used by anyone
as far as I know. This removes this option entirely in favor of
Alacritty's built-in logger level selection flags.
This resolves an issue where trying to write a fullwidth character in
the last column would crash Alacritty, if linewrapping was disabled.
Instead of assuming that the linewrap put after the linewrapping spacer
was successful, the character writing is now skipped completely when
trying to put a wide character in the last column.
Instead of blocking on vsync, Alacritty now requests a notification from
wayland about when the next frame should be rendered. this helps with
input latency, since it gives alacritty more time to process events
before a redraw. it also prevents alacritty from drawing unless the
compositor tells it to do so.
Fixes#2851.
On X11 `swap_buffers` does not block for vsync. However the next OpenGl command
will block to synchronize (this is `glClear` in Alacritty), which causes a
permanent one frame delay.
Calling `glFinish` after swapping buffers forces Alacritty to finish the buffer
swap before returning control to the event loop.
Fixes#3061.
This fixes a regression introduced in 4cc6421, which ignored the main
grid's cursor when increasing the number of lines available, causing
incorrect cursor position after restoring to the primary screen.
Additionally another similar bug has been fixed where the grid was not
scrolled correctly when shrinking while in the alternate screen.
When the grid is resized multiple lines at once, there was also an issue
with Alacritty either pulling all lines from history or none at all,
instead of mixing both approaches and pulling just what is required.
This lead to incorrect cursor positions when the resize could partially
make use of history.
Fixes#3499.
This implements a basic mode for navigating inside of Alacritty's
history with keyboard bindings. They're bound by default to vi's motion
shortcuts but are fully customizable. Since this relies on key bindings
only single key bindings are currently supported (so no `ge`, or
repetition).
Other than navigating the history and moving the viewport, this mode
should enable making use of all available selection modes to copy
content to the clipboard and launch URLs below the cursor.
This also changes the rendering of the block cursor at the side of
selections, since previously it could be inverted to be completely
invisible. Since that would have caused some troubles with this keyboard
selection mode, the block cursor now is no longer inverted when it is at
the edges of a selection.
Fixes#262.
This enables live config reload for the window title. This includes
updating the title after it has been pushed and popped from the title
stack.
The dynamic title option also isn't disabled automatically anymore when
the title is set in the config. If the title is set from CLI, the
behavior is unchanged and dynamic title changes are still disabled.
If the dynamic title is disabled in the config, the title is still
updated when the config title is changed. Dynamic title now only
prevents changes to the UI's title.
This resolves an issue with the selection clamping, where no selection
would be rendered at all when the start was above the viewport while the
end was below it.
This completely removes the tabspaces option from the Alacritty
configuration, due to frequent misuse of it. Based on some research,
none of the terminal emulators support setting the value for tabspaces
or read the terminfo to determine init_tabs value at startup. The tested
terminal emulators were URxvt, XTerm, and Termite.
This resolves an issue with tabs not breaking across line boundaries,
instead the characters would just all get written to the last column and
thus be lost.
It also tweaks the behavior of what happens when the terminal resizes
with the default tabspaces changed, using something like the `tabs`
program. Previously all tabstops would be reset to the default on
resize, which is what URxvt does. Now the tabspaces are kept and the new
columns are filled with the default tabstops, which emulates Termite.
Previously we were rounding pattern's `pixelsize` before `fc_sort`, however we were using not rounded one in `get_glyph`, so bitmap fonts could look a bit smaller when used in a mix with scalable fonts.
The block selection will now only insert extra newline characters after
each line if the last line isn't already included. This resolves an
issue with duplicate newlines, since newlines are automatically appended
when the last column is part of a selection.
Fixes#3304.
