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
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:
#0 0x7f7e95cbfa89 in __interceptor_malloc /build/gcc/src/gcc/libsanitizer/asan/asan_malloc_linux.cpp:69
#1 0x7f7e95bd1fe5 (/usr/lib/libfontconfig.so.1+0x20fe5)
Indirect leak of 96 byte(s) in 3 object(s) allocated from:
#0 0x7f7e95cbf411 in __interceptor_calloc /build/gcc/src/gcc/libsanitizer/asan/asan_malloc_linux.cpp:77
#1 0x7f7e95bd63fd (/usr/lib/libfontconfig.so.1+0x253fd)
Indirect leak of 19 byte(s) in 2 object(s) allocated from:
#0 0x7f7e95c72faa in __interceptor_strdup /build/gcc/src/gcc/libsanitizer/asan/asan_interceptors.cpp:439
#1 0x7f7e95bd1898 in FcValueSave (/usr/lib/libfontconfig.so.1+0x20898)
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.
Fixes#1136
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)'
conf_color = &term->conf->csd.color.close;

/usr/local/include/libepoll-shim/epoll-shim/detail/common.h:8:15:
note: expanded from macro 'close': #define close epoll_shim_close
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
