Summary of changes:
* Make xvsnprintf() static
* restrict-qualify pointer arguments (as done by the libc equivalents)
* Make comments and spec references more thorough
* Remove pointless `n <= INT_MAX` assertion (see comment)
* Use FATAL_ERROR() instead of xassert() (since the assertion is inside
a shared util function but the caller is responsible for ensuring the
condition holds true)
* Change some callers to use size_t instead of int for the return value
(negative returns are impossible and all subsequent uses are size_t)
The updated comments and code were taken (and adapted) from:

That is, skip the reverse DNS naming scheme suggested by the .desktop
specification, and directly match our app-ids ("foot", and
"footclient").
This simplifies .desktop -> window instance mapping, allowing DEs to
match the filenames directly, without having to look at the
StartupWMClass key in the .desktop files.
These are the original names of the .desktop files. There were
renamed (to use the reverse DNS syntax) to please the flathub people,
who *required* this scheme to accept the foot package.
But, since:
* We don't package foot ourselves
* We don't go out of our way to support non-distro packaging schemes
* Flathub still hasn't merged the foot PR (it's now 2 years old)
* There are no know issues in any known DE that prevents a non-reverse
DNS .desktop filename from working
* There are plenty of other applications that doesn't use reverse DNS
names (a very clear majority, in my case)
Let's just revert back to the simpler naming scheme.
Closes#1607
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.
At compile time, build a lookup table from the Unicode data file
'emoji-variation-sequences.txt'.
At run-time, when we detect a VS-15/16 sequence, do a lookup in this
table, and enforce the variation selector iff the sequence is valid.
Closes#1742
The unicode-mode, and flash overlays are single color buffers. This
means we can use the single-pixel buffer protocol.
It's undefined whether the compositor will release the buffer or not;
to make things easier, simply destroy the buffer as soon as we've
committed it.
Note that since compositors don't necessarily release single-pixel
buffers, we can't plug them into our own buffer interface. This means
we can't use buffer pointers to check if we can re-use the previous
buffer (i.e. we can skip comitting a new buffer), or if we have to
create a new one.
It's _almost_ enough to just check if the last overlay style is the
same as the current one. Except that that doesn't take window resizes
into account...
This defines the base name of the generated terminfo files. It
defaults to the value of -Ddefault-terminfo (i.e. 'foot')
Example:
meson -Ddefault-terminfo=foot-bananas -Dterminfo-base-name=foot-apples
The generated terminfo files will be
* terminfo/f/foot-apples
* terminfo/f/foot-apples-direct
The default value of $TERM will be 'foot-bananas'
- wayland-instance template target was a mistake.
Systemd does not support simultaneous same user session, so stop
trying to go against that.
- Only start systemd units in Wayland environments.
This patch assumes a git snapshot of wayland-protocols are
installed.
We need to bump the version number as soon as the next version of
wayland-protocols have been released.
This implements support for the new cursor-shape-v1 protocol. When
available, we use it, instead of client-side cursor surfaces, to
select the xcursor shape.
Note that we still need to keep client side pointers, for:
* backward compatibility
* to be able to "hide" the cursor
Closes#1379
This patch generalizes the utmp support, to not only support
libutempter, but also ulog (and in the future, even more interfaces).
* Rename config option main.utempter to main.utmp-helper
* Add meson option -Dutmp-backend=none|libutempter|ulog|auto
* Rename meson option -Ddefault-utempter-path to -Dutmp-default-helper-path
* utmp is no longer detected at compile time, but at runtime instead.
Meson will configure the following pre-processor macros, based on the
selected utmp backend:
* UTMP_ADD - argument to pass to utmp helper when adding a record (starting foot)
* UTMP_DEL - argument to pass to utmp helper when removing a record (exiting foot)
* UTMP_DEL_HAVE_ARGUMENT - if defined, UTMP_DEL expects an extra argument ($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.
Closes#1314
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.
