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 $TERM will be 'foot-bananas'
This patch generalizes the utmp support, to not only support
libutempter, but also ulog (and in the future, even more interfaces).
* Rename config option main.utempter to main.utmp-helper
* Add meson option -Dutmp-backend=none|libutempter|ulog|auto
* Rename meson option -Ddefault-utempter-path to -Dutmp-default-helper-path
* utmp is no longer detected at compile time, but at runtime instead.
Meson will configure the following pre-processor macros, based on the
selected utmp backend:
* UTMP_ADD - argument to pass to utmp helper when adding a record (starting foot)
* UTMP_DEL - argument to pass to utmp helper when removing a record (exiting foot)
* UTMP_DEL_HAVE_ARGUMENT - if defined, UTMP_DEL expects an extra argument ($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
We execute xtgettcap in the parent terminal. Thus we don’t know if it
implements XTGETTCAP, and thus it’s not guaranteed to exit - it may
hang indefinitely waiting for a reply.
Fix by not actually quering anything.
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 allows package maintainers to override the location to which our
systemd service files are installed.
It’s value is an *absolute* path, and *not* relative ${prefix}.
The default is ${systemduserunitdir}.
- foot.ini.5: mention location of example config file
- foot.1: replace outdated (or incomplete) information about the
location of the config file with references to foot.ini.5
- foot.1 and foot.ini.5: conform to scdoc specification, thus surround each
header with (at least) one blank line. additionally consistently use exactly
one line before/after each header (was sometimes two before)
- foot.1: some parts of the keybindings had their own section, move into
KEYBOARD SHORTCUTS section
- foot.1: move EXIT STATUS section to the end where it is commonly found
- foot.1: copy information about config file handling from the beginning of
foot.ini.5 into the CONFIGURATION section of foot.1
- INSTALL.md: foot.ini is no longer included in the documentation
- meson.build: do not bundle foot.ini with documentation anymore, see also

Grapheme shaping is now enabled by default in foot. However, when
generating the profiling data in PGO builds, this results in skewed
optimizations.
The end result is worse benchmark results regardless of whether
grapheme-shaping is enabled or not (when running the benchmarks).
That locale may not exist. Instead, require the user/build script to
explicitly set an UTF-8 locale.
Document this in INSTALL.md, and in the bundled PKGBUILD.
The meson command line option -Dcustom-terminfo-install-location has
been changed in the following ways:
* If unset, $datadir/terminfo is used, and TERMINFO is *not* exported
* If set, that value (relative to $prefix) is used, and TERMINFO *is*
exported.
* The special value ‘no’ is removed.
-Ddefault-terminfo now also changes the terminfo names generated when
-Dterminfo=enabled.
Furthermore, the documentation for the TERMINFO environment variable
has been removed from the foot.1 and footclient.1 man pages (but as
mentioned above, foot *will* still set it if
-Dcustom-terminfo-install-location has been used).
INSTALL.md has been updated to now recommend using ncurses’ terminfo
definitions, if available. But also to document the other
alternatives; installing the terminfo definitions in a custom
location, or installing them with a diferent name. It also describes
the general problem, and the disadvantages of each alternative (but
without going into too much depth).
This seems to be slightly better supported than TERMINFO_DIRS. It also
simplifies our code, since it’s no longer an issue of whether to
append or not - we just set TERMINFO, and ignore whatever it was set
to before.
Also closes#687
As of 2021-07-31, ncurses ships its own version of foot’s terminfo.
Since:
* It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb
capabilities.
* It doesn’t set hs,fsl,dsl (statusbar).
* We want to be able to update our termminfo without waiting for an
ncurses release.
* Foot should be installable and usable on Linux systems that doesn’t
have the latest ncurses.
we still want to ship our own version. We can however not install it
to the default terminfo location (e.g. /usr/share/terminfo), since it
will collide with the ncurses provided files.
Our options are to either rename our terminfo to something else, or to
keep the name, but install our terminfo files somewhere else.
The first option would be the easy one. However, I think it makes
sense to use the same name. For example, a user that SSH’s into a
remote system that does *not* have our own version installed,
but *does* have the ncurses one, will gracefully fall back to that
one, which is better than manually having to set
e.g. TERM=xterm-256color.
Now, if we want to use the same name, we need to install it somewhere
else. But where? And how do we ensure our version is preferred over
the ncurses one?
I opted to $datadir/foot/terminfo (e.g. /usr/share/foot/terminfo) by
default. It makes it namespaced to foot (i.e. we’re not introducing a
new “standard” terminfo location), thus guaranteeing it wont collide
with ncurses.
To enable applications to find it, we export TERMINFO_DIRS. This is a
list of *additional* directories to search for terminfo files. If it’s
already defined, we *append* to it.
The nice thing with this is, if there’s no terminfo in that
location (e.g. when you SSH into a remote), the default terminfo
location is *also* searched. But only *after* having searched through
TERMINFO_DIRS.
In short: our version is preferred, but the ncurses one (or an older
version of our terminfo package!) will be used if ours cannot be
found.
To enable packagers full control over the new behavior, the existing
meson command line options have been modified, and a new option added:
-Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo
files.
-Dcustom-terminfo-install-location=<path>: *where* the terminfo files
are expected to be found.
This *needs* to be set *even* if -Dterminfo=disabled. For example, if
the packaging script builds and packages the terminfo files separate
from the regular foot build. The path is *relative to $prefix*, and
defaults to $datadir/foot/terminfo.
This is the value that will be appended to TERMINFO_DIRS. Note that
you can set it to ‘no’, in which case foot will *not* set/modify
TERMINFO_DIRS. Only do this if you don’t intend to package foot’s
terminfo files at all (i.e. you plan on using the ncurses ones only).
-Ddefault-terminfo=foot. Allows overriding the default TERM
value. This should only be changed if the target platform doesn’t
support terminfo files.
Closes#671
And flesh out the description of the ‘terminfo’ option, and how it
relates to the new ‘terminfo-install-location’.
Also add instructions on how to manually generate the terminfo files.
While skimming this doc, I noticed that "-Dterminfo" wasn't rendering
properly as it was lacking its closing backquote.
While at it, tweak the Arch wiki link, as it redirects to replace
/index.php with /title.
While we don’t (yet) have any unit tests for foot, users can build
foot with e.g. fcft and/or tllist as sub-projects. *They* have tests,
and when doing PGO builds, those test binaries *must* be executed, or
we get link failures in the final build.
LLVM/Clang 11.x throws errors for _files_ without any profiling data:
error: ../../async.c: Function control flow change detected (hash mismatch) async_write Hash = 72057641800614222 [-Werror,-Wbackend-plugin]
This caused multiple issues with the current PGO instructions:
* The `pgo` binary failed to link with `meson configure -Db_pgo=use`
when doing a full PGO build (since it isn't used in this case);
* `footclient` fails to link for the same reason.
* `foot` fails to link for the same reason in **partial** PGO builds.
The solution is to make sure all binaries that are built in the final
phase (`-Db_pgo=use`) have been executed in the _generate_ phase.
Doing this also means we can drop `-Wno-missing-profile` and friends.
Also add `--sixel` to the `generate-alt-random-writes` command line in
the description for a full PGO build.
Closes#418
* use toe for terminfo, thanks Craig.
* adds optional dependency on bash-completion for positional arguments
