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.
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.
* 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'.
Move main.alpha-mode to colors.alpha-mode.
Fix (inverted) cursor handling, by always using the bg color without
alpha.
Do a minor optimization, where we don't even lock at colors.alpha-mode
if there's no transparency configured.
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
Zero-initialize the 'launch' spawn template before calling
value_to_spawn_template(). This is needed since
value_to_spawn_template() tries to free the old value before assigning
the new one.
Closes#1951
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.
Users can now define their own regex patterns, and use them via key
bindings:
[regex:foo]
regex=foo(bar)?
launch=path-to-script-or-application {match}
[key-bindings]
regex-launch=[foo] Control+Shift+q
regex-copy=[foo] Control+Mod1+Shift+q
That is, add a section called 'regex:', followed by an
identifier. Define a regex and a launcher command line.
Add a key-binding, regex-launch and/or regex-copy (similar to
show-urls-launch and show-urls-copy), and connect them to the regex
with the "[regex-name]" syntax (similar to how the pipe-* bindings
work).
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.
A compositor will not send a frame callback for our main window if it
is fully occluded (for example, by a fully opaque overlay...). This
causes the overlay to stuck.
For regular buffers, it _should_ be enough to *not* hint the
compositor it's opaque. But at least some compositor special cases
single-pixel buffers, and actually look at their pixel value.
Thus, we have two options: implement frame callback handling for the
overlay sub-surface, or ensure we don't use a fully opaque
surface. Since no overlays are fully opaque by default, and the flash
surface is the only one that can be configured to be
opaque (colors.flash-alpha), and since adding frame callback handling
adds a lot of boilerplate code... let's go with the simpler solution
of
This implements part of the new 's' (sound) parameter; the 'silent'
value. When s=silent, we set the ${muted} template argument to
"true". It is intended to set the 'suppress-sound' hint:
notify-send --hint BOOLEAN:suppress-sound:${muted}
This avoids the need for an unused third argument for most xstrjoin()
calls and replaces the cases where it's needed with a more flexible
function. Code generation is the same in both cases, when there are 2
string params and a compile-time known delimiter.
This commit also converts 4 uses of xasprintf() to use xstrjoin*().

* Don't store a list of unfinished notifications. Use a single one. If
the notification ID of the 'current' notification doesn't match the
previous, unfinished one, the 'current' notification replaces the
previous one, instead of updating it.
* Update xstrjoin() to take an optional delimiter (for example ','),
and use that when joining categories and 'alive IDs'.
* Rename ${action-arg} to ${action-argument}
* Update handling of the 'n' parameter (symbolic icon name); the spec
allows it to be used multiple times, and the terminal is supposed to
pick the first one it can resolve. Foot can't resolve icons at all,
neither can 'notify-send' or 'fyi' (which is what foot typically
executes to display a notification); it's the notification daemon that
resolves icons.
The spec _could_ be interpreted to mean the terminal should lookup
.desktop files, and use the value of the 'Icon' key from the first
matching .desktop files. But foot doesn't read .desktop files, and I
don't intend to implement XDG directory scanning and parsing of
.desktop files just to figure out which icon to use.
Instead, use a simple heuristics; use the *shortest* symbolic
names. The idea is pretty simple: plain icon names are typically
shorter than .desktop file IDs.
First, icons have been finalized in the specification. There were only
three things we needed to adjust:
* symbolic names are base64 encoded
* there are a couple of OSC-99 defined symbolic names that need to be
translated to the corresponding XDG icon name.
* allow in-band icons without a cache ID (that is, allow applications
to use p=icon without having to cache the icon first).
Second, add support for the following new additions to the protocol:
* 'f': custom app-name, overrides the terminal's app-id
* 't': categories
* 'p=alive': lets applications poll for currently active notifications
* 'id' is now 'unset' by default, rather than "0"
* 'w': expire time (i.e. notification timeout)
* "buttons": aka actions. This lets applications add additional (to
the terminal defined "default" action) actions. The 'activated' event
has been updated to report which button/action was used to activate
the notification.
To support button/actions, desktop-notifications.command had to be
reworked a bit.
There's now a new config option:
desktop-notifications.command-action-arg. It has two template
arguments ${action-name} and ${action-label}.
command-action-arg gets expanded for *each* action.
${action-name} and ${action-label} has been replaced by ${action-arg}
in command. This is a somewhat special template, in that it gets
replaced by *all* instances of the expanded actions.
Add a new config option, desktop-notifications.close, defining what to
execute to close a notification. It has a single template parameter,
${id}, that is expanded to the external notification ID foot may have
picked up from the notification helper.
notify-send does not support closing notifications, and it appears
impossible to pass an *unsigned* integer as argument to gdbus. Hence
no default value for the new 'close' option.
Example:
printf '\e]99;i=123;this is a notification\e\\'
printf '\e]99;i=123:p=close;\e\\'
Split it up into two, ${action-name} and ${action-label}.
Dunstify, for example, has a different syntax compared to notify-send:
notify-send: default=foobar
dunstify: default,foobar
Only do it when the notification was activated.
Here, activated means the 'click to activate' notification action was
triggered.
How do we tie everything together?
First, we add a new template parameter, ${action}. It's intended to be
used with e.g. notify-send's --action option.
When the action is triggered, notify-send prints its name on stdout,
on a separate line. Look for this in stdout. Only if we've seen it do
we focus/report the notification.
This patch adds support for window focusing, and sending events back
to the client application when a notification is closed.
* Refactor notification related configuration options:
- add desktop-notifications sub-section
- deprecate 'notify' in favor of 'desktop-notifications.command'
- deprecate 'notify-focus-inhibit' in favor of
'desktop-notifications.inhibit-when-focused'
* Refactor: rename 'struct kitty_notification' to 'struct
notification'
* Pass a 'struct notification' to notify_notify(), instead of many
arguments.
* notify_notify() now registers a reaper callback. When the notifier
process has terminated, the notification is considered closed, and we
either try to focus (activate) the window, or send an event to the
client application, depending on the notification setting.
* For the window activation, we need an XDG activation token. For now,
assume *everything* written on stdout is part of the token.
* Refactor: remove much of the warnings from OSC-99; we don't
typically log anything when an OSC/CSI has invalid values.
* Add icon support to OSC-99. This isn't part of the upstream
spec. Foot's implementation:
- uses the 'I' parameter
- the value is expected to be a symbolic icon name
- a quick check for absolute paths is done, and such icon requests
are ignored.
* Added ${icon} to the 'desktop-notifications.command' template. Uses
the icon specified in the notification, or ${app-id} if not set.
This adds limited support for OSC-99, kitty desktop notifications[^1]. We
support everything defined by the "protocol", except:
* 'a': action to perform on notification activation. Since we don't
trigger the notification ourselves (over D-Bus), we don't know a)
which ID the notification got, or b) when it is clicked.
* ... and that's it. Everything else is supported
To be explicit, we *do* support:
* Chunked notifications (d=0|1), allowing the application to append
data to a notification in chunks, before it's finally displayed.
* Plain UTF-8, or base64-encoded UTF-8 payload (e=0|1).
* Notification identifier (i=xyz).
* Payload type (p=title|body).
* When to honor the notification (o=always|unfocused|invisible), with
the following quirks:
- we don't know when the window is invisible, thus it's treated as
'unfocused'.
- the foot option 'notify-focus-inhibit' overrides 'always'
* Urgency (u=0|1|2)

BTN_BACK and BTN_FORWARD are separate buttons. The scroll wheel don't
have any button mappings in libinput/wayland, so make up our own
defines.
This allows us to map them in mouse bindings.
Also expose BTN_WHEEL_{LEFT,RIGHT}. These were already defined, and
used, internally, to handle wheel tilt events. With this, they can
also be used in mouse bindings.
Finally, fix encoding used for BTN_{BACK,FORWARD} when sending mouse
button events to the client application. Before this, they were mapped
to buttons 4/5. But, button 4/5 are for the scroll wheel, and as
mentioned above, BTN_{BACK,FORWARD} are not the same as scroll wheel
"buttons".
