Before this patch, the grid content was *always* centered when the
window was maximized or fullscreened, regardless of how the user had
configured padding.
Now, the behavior is controlled by the 'pad' option. Before this
patch, the syntax was
pad MxN [center]
Now it is
pad MxN [center|center-when-fullscreen|center-when-maximized-and-fullscreen]
The default is "pad 0x0 center-when-maximized-and-fullscreen", to
match current behavior.
Closes#2111
Before this, we only applied custom selection colors, if *both* the
selection bg and fg had been set.
Since the options are already split up into two separate options, and
since it makes sense to at least be able to keep the foreground colors
unchanged (i.e. only setting the selection background), let's allow
only having one of the selection colors set.
Closes#1846
This adds supports for 16-bit surfaces, using the new
PIXMAN_a16b16g16r16 buffer format. This maps to
WL_SHM_FORMAT_ABGR16161616 (little-endian).
Use the new 16-bit surfaces by default, when
gamma-correct-blending=yes.
In copy-regex/show-urls-copy mode, if the last input character was
uppercase, copy the selection to the clipboard _and_ paste it. This is
useful for taking a file path from a command output:(log, git, test
failure, etc.) and using it in another command.
This is inspired by the behavior of copy mode in wezterm:
https://wezterm.org/quickselect.html
I could have made it check every character in the hint, but it seemed
fine to assume that if the last character was uppercase, the user
wanted this behavior.
Closes#1975.
When set to 'auto', use 10-bit surfaces if gamma-correct blending is
enabled, and 8-bit surfaces otherwise.
Note that we may still fallback to 8-bit surfaces (without disabling
gamma-correct blending) if the compositor does not support 10-bit
surfaces.
Closes#2082
This option selects which color theme to use by default. I.e. at
startup, and after a reset.
This is useful with combined theme files, where a single file defines
e.g. both a dark and light version of the theme.
* Recognize 'CSI ? 996 n', and respond with
- 'CSI ? 997 ; 1 n' if the primary theme is active
- 'CSI ? 997 ; 2 n' if the alternative theme is actice
* Implement private mode 2031, where changing the color
theme (currently only possible via key bindings) causes the terminal
to send the same CSI sequences as above.
In this context, foot's primary theme is considered dark, and the
alternative theme light (since the default theme is dark).
Closes#2025
* color-theme-switch-1: select the primary color theme
* color-theme-switch-2: select the alternative color theme
* color-theme-toggle: toggle between the primary and alternative color themes
This section defines an alternative color theme. The keys are the same
as in the 'colors' section, as are the default values.
Values are *not* inherited from 'colors'. That is, if you set a value
in 'colors', but not in 'colors2', it is *not* inherited by 'colors2'.
The old one is in some cases too liberal. The new one is stricter in
two ways:
1. The protocol list is now explicit, rather than matching anything://
2. Allowed characters are now limited to the "safe character set", the
"reserved character set", and some from the "unsafe character set"
Furthermore, some of the characters are restricted in how/when they
are allowed:
1. Periods, commas, question marks etc are allowed inside an URL, but
not at the end.
2. [ ], ( ), " " and ' ' are allowed but only when balanced. This
allows us to match e.g. [http://foo.bar/foo[bar]] correctly.
Closes#2016
Update tweak.scaling-filter to recognize the new scaling filters added
in fcft-3.3.0.
Since fcft_set_scaling_filter() is deprecated in 3.3.0, don't use it
anymore, and set the scaling filter via fcft_font_options instead.
This implements gamma-correct blending, which mainly affects font
rendering.
The implementation requires compile-time availability of the new
color-management protocol (available in wayland-protocols >= 1.41),
and run-time support for the same in the compositor (specifically, the
EXT_LINEAR TF function and sRGB primaries).
How it works: all colors are decoded from sRGB to linear (using a
lookup table, generated in the exact same way pixman generates it's
internal conversion tables) before being used by pixman. The resulting
image buffer is thus in decoded/linear format. We use the
color-management protocol to inform the compositor of this, by tagging
the wayland surfaces with the 'ext_linear' image attribute.
Sixes: all colors are sRGB internally, and decoded to linear before
being used in any sixels. Thus, the image buffers will contain linear
colors. This is important, since otherwise there would be a
decode/encode penalty every time a sixel is blended to the grid.
Emojis: we require fcft >= 3.2, which adds support for sRGB decoding
color glyphs. Meaning, the emoji pixman surfaces can be blended
directly to the grid, just like sixels.
Gamma-correct blending is enabled by default *when the compositor
supports it*. There's a new option to explicitly enable/disable it:
gamma-correct-blending=no|yes. If set to 'yes', and the compositor
does not implement the required color-management features, warning
logs are emitted.
There's a loss of precision when storing linear pixels in 8-bit
channels. For this reason, this patch also adds supports for 10-bit
surfaces. For now, this is disabled by default since such surfaces
only have 2 bits for alpha. It can be enabled with
tweak.surface-bit-depth=10-bit.
Perhaps, in the future, we can enable it by default if:
* gamma-correct blending is enabled
* the user has not enabled a transparent background
When auto-matching URLs (or custom regular expressions), use the
first *subexpression* as URL, rather than the while regex match.
This allows us to write custom regular expressions with prefix/suffix
strings that should not be included in the presented match.
From the release notes:
system bell - allowing e.g. terminal emulators to hand off system
bell alerts to the compositor for among other things accessibility
purposes
The new protocol is used when the new config option
bell.system=yes (and the compositor implements the protocol,
obviously).
The system bell is rung independent of whether the foot window has
keyboard focus or not (thus relying on compositor configuration to
determine whether anything should be done or not in response to the
bell).
The new option is enabled by default.
* The toplevel icon is now set to the app-id, unless "overridden" by
OSC-1 or OSC-0.
* Implemented OSC-1
* OSC-0 extended to also set the icon
* Implemented CSI 20 t - report window icon
* Implemented CSI 21 t - report window title
* Implemented CSI 22 ; 1 t - push window icon
* Implemented CS 23 ; 1 t - pop window icon
* Extended CSI 22/23 ; 0 t to also push/pop the icon
* Verify app-id set by OSC-176 is valid UTF-8
* Verify icon set by OSC-0/1 is valid UTF-8
