This allows the user to configure the value by which a surface
buffer's stride must be an even multiple of.
This can be used to ensure the stride meets the GPU driver's
requirements for direct import.
Defaults to 256. Set to 0 to disable.

This makes the "uppercase hint character inserts selected text"
behavior added in #1975 configurable, as it can have unexpected
behavior for some users.
It defaults to "on", preserving the new behavior of `foot`, after
Fixes#2159.
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.
* 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.
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.
The back-reference to 'tokenize.c' in the parent directory causes PGO
build failures, where gcc can't find the PGO data. Likely due to
path/naming issues caused by meson's generated build directories.
This option controls how we render the cursor when the terminal window
is unfocused.
Possible values are:
* hollow: the default, and how we rendered the cursor before this
patch.
* unchanged: render the cursor exactly the same way as when the window
is focused.
* none: do not render any cursor at all
Closes#1582
That is, allow custom modifiers (i.e. other than ctrl/shift/alt etc)
in key bindings.
This is done by no longer validating/translating modifier names to
booleans for a pre-configured set of modifiers (ctrl, shift, alt,
super).
Instead, we keep the modifier *names* in a list, in the key binding
struct.
When a keymap is loaded, and we "convert" the key binding, _then_ we
do modifier translation. For invalid modifier names, we print an
error, and then ignore it. I.e. we no longer fail to load a config due
to invalid modifier names.
We also need to update how we determine the set of significant
modifiers. Any modifier not in this list will be ignored when matching
key bindings.
Before this patch, we hardcoded this to shift/alt/ctrl/super. Now, to
handle custom modifiers as well, we simply treat *all* modifiers
defined by the current layout as significant.
Typically, the only unwanted modifiers are "locked" modifiers. We are
already filtering these out.
Reject color values that aren't in either RGB, or ARGB format. That
is, color values that aren't hexadecimal numbers with either 6 or 8
digits.
Also, if a color value is allowed to have an alpha component, and the
user left it out, default to 0xff (opaque) rather than 0x00 (fully
transparent).
Closes#1526
By how much to increase the luminance when brightening bold
fonts. This was previously hard-coded to a factor of 1.3, which is now
the default value of the new config option.
Closes#1434
When enabled, double-clicking the CSD titlebar will (un)maximize the
window.
Defaults to ‘yes’ (since this is the old hard-coded behavior).
Closes#1293
We now default to scaling fonts using the scaling factor, not monitor
DPI.
The ‘auto’ value for dpi-aware has been removed.
Documentation (man pages and README) have been updated to reflect the
new default.
This patch generalizes the utmp support, to not only support
libutempter, but also ulog (and in the future, even more interfaces).
* Rename config option main.utempter to main.utmp-helper
* Add meson option -Dutmp-backend=none|libutempter|ulog|auto
* Rename meson option -Ddefault-utempter-path to -Dutmp-default-helper-path
* utmp is no longer detected at compile time, but at runtime instead.
Meson will configure the following pre-processor macros, based on the
selected utmp backend:
* UTMP_ADD - argument to pass to utmp helper when adding a record (starting foot)
* UTMP_DEL - argument to pass to utmp helper when removing a record (exiting foot)
* UTMP_DEL_HAVE_ARGUMENT - if defined, UTMP_DEL expects an extra argument ($WAYLAND_DISPLAY)
* UTMP_DEFAULT_HELPER_PATH - path to the default utmp helper binary
The documentation has been updated to mention which arguments are
passed to the helper binary.

Some of the config options we’re testing result in calls to FontConfig
APIs. Without calling FcIni()+FcFini(), we leak memory:
Direct leak of 768 byte(s) in 3 object(s) allocated from:

This patch adds a new config option, font-size-adjustment.
It lets you configure how much the font size should be
incremented/decremented when zooming in or out (ctrl-+, ctrl+-).
Values can be specified in points, pixels or percent.
Closes#1188
This patch adds support for creating utmp records using the ‘utempter’
helper binary from the ‘libutempter’ package.
* New config option ‘main.utempter’
* New meson command line option, -Ddefault-utempter-path. Defaults to
auto-detecting the path.
The default value of the new ‘main.utempter’ config option depends on
the meson command line option ‘-Ddefault-utempter-path’.
If ‘main.utempter’ is *not* set to ‘none’, foot will try to execute
the utempter helper binary to create utmp records when a new terminal
is instantiated. The record is removed when the terminal instance is
destroyed.
This adds an "underline-thickness" setting to the "main" section,
similar to the existing "underline-offset" setting. This setting is used
to specify a custom height for regular (= non-cursor) underlines.

This fixes a compilation error on FreeBSD:
../../foot/render.c:2055:45: error: no member named 'epoll_shim_close' in 'struct config::(anonymous at ../../foot/config.h:254:9)'

Fcft no longer uses wchar_t, but plain uint32_t to represent
codepoints.
Since we do a fair amount of string operations in foot, it still makes
sense to use something that actually _is_ a string (or character),
rather than an array of uint32_t.
For this reason, we switch out all wchar_t usage in foot to
char32_t. We also verify, at compile-time, that char32_t used
UTF-32 (which is what fcft expects).
Unfortunately, there are no string functions for char32_t. To avoid
having to re-implement all wcs*() functions, we add a small wrapper
layer of c32*() functions.
These wrapper functions take char32_t arguments, but then simply call
the corresponding wcs*() function.
For this to work, wcs*() must _also_ be UTF-32 compatible. We can
check for the presence of the __STDC_ISO_10646__ macro. If set,
wchar_t is at least 4 bytes and its internal representation is UTF-32.
FreeBSD does *not* define this macro, because its internal wchar_t
representation depends on the current locale. It _does_ use UTF-32
_if_ the current locale is UTF-8.
Since foot enforces UTF-8, we simply need to check if __FreeBSD__ is
defined.
Other fcft API changes:
* fcft_glyph_rasterize() -> fcft_codepoint_rasterize()
* font.space_advance has been removed
* ‘tags’ have been removed from fcft_grapheme_rasterize()
* ‘fcft_log_init()’ removed
* ‘fcft_init()’ and ‘fcft_fini()’ must be explicitly called
