NAME

footclient - start new terminals in a foot server

SYNOPSIS

footclient [OPTIONS]
footclient [OPTIONS] <command> [COMMAND OPTIONS]

All trailing (non-option) arguments are treated as a command, and its arguments, to execute (instead of the default shell).

DESCRIPTION

footclient is used together with foot(1) in --server mode.

Running it without arguments will open a new terminal window (hosted in the foot server), with your default shell. The exit code will be that of the terminal. I.e footclient does not exit until the terminal has terminated.

OPTIONS

-t,--term=TERM

Value to set the environment variable TERM to (see TERMINFO and ENVIRONMENT). Default: xterm-256color.

-T,--title=TITLE

Initial window title. Default: foot.

-a,--app-id=ID

Value to set the app-id property on the Wayland window to. Default: foot.

-w,--window-size-pixels=WIDTHxHEIGHT

Set initial window width and height, in pixels. Default: 700x500.

-W,--window-size-chars=WIDTHxHEIGHT

Set initial window width and height, in characters. Default: not set.

-m,--maximized

Start in maximized mode. If both --maximized and --fullscreen are specified, the last one takes precedence.

-F,--fullscreen

Start in fullscreen mode. If both --maximized and --fullscreen are specified, the last one takes precedence.

-L,--login-shell

Start a login shell, by prepending a '-' to argv[0].

-D,--working-directory=DIR

Initial working directory for the client application. Default: CWD of footclient.

-s,--server-socket=PATH

Connect to PATH instead of $XDG_RUNTIME_DIR/foot-$WAYLAND_DISPLAY.sock.

-H,--hold

Remain open after child process exits.

-N,--no-wait

Detach the client process from the running terminal, exiting immediately.

-o,--override=[SECTION.]KEY=VALUE

Override an option set in the configuration file. If SECTION is not given, defaults to main.

-d,--log-level={info,warning,error,none}

Log level, used both for log output on stderr as well as syslog. Default: info.

-l,--log-colorize=[{never,always,auto}]

Enables or disables colorization of log output on stderr.

-v,--version

Show the version number and quit

-e

Ignored; for compatibility with xterm -e. See foot(1) for more details.

EXIT STATUS

Footlient will exit with code 220 if there is a failure in footclient itself (for example, the server socket does not exist).

If -N,--no-wait is used, footclient exits with code 0 as soon as the foot server has been instructed to open a new window.

If not, footclient may also exit with code 230. This indicates a failure in the foot server.

In all other cases the exit code is that of the client application (i.e. the shell).

TERMINFO

Client applications use the terminfo identifier specified by the environment variable TERM (set by foot) to determine terminal capabilities.

Foot has two terminfo definitions: foot and foot-direct, with foot being the default.

The difference between the two is in the number of colors they describe; foot describes 256 colors and foot-direct 16.7 million colors (24-bit truecolor).

Note that using the foot terminfo does not limit the number of usable colors to 256; applications can still use 24-bit RGB colors. In fact, most applications work best with foot (including 24-bit colors)). Using *-direct terminfo entries has been known to crash some ncurses applications even.

There are however applications that need a *-direct terminfo entry for 24-bit support. Emacs is one such example.

While using either foot or foot-direct is strongly recommended, it is possible to use e.g. xterm-256color as well. This can be useful when remoting to a system where foot's terminfo entries cannot easily be installed.

Note that terminfo entries can be installed in the user's home directory. I.e. if you do not have root access, or if there is no distro package for foot's terminfo entries, you can install foot's terminfo entries manually, by copying foot and foot-direct to ~/.terminfo/f/.

ENVIRONMENT

The following environment variables are used by footclient:

XDG_RUNTIME_DIR

Used to construct the default PATH for the --server-socket option, when no explicit argument is given (see above).

WAYLAND_DISPLAY

Used to construct the default PATH for the --server-socket option, when no explicit argument is given (see above).

The following environment variables are set in the child process:

TERM

terminfo/termcap identifier. This is used by client applications to determine which capabilities a terminal supports. The value is set according to either the --term command-line option or the term config option in foot.ini(5).

COLORTERM

This variable is set to truecolor, to indicate to client applications that 24-bit RGB colors are supported.
