Kitty is a low-latency, full-featured, modern, terminal emulator, written in C and Python, that offloads rendering to the GPU. Kitty is designed for speed, functionality, and extensibility, aiming for the ideal balance of useful functionality against bloat. By default, a little performance is traded-off against usability, though this can be adjusted.
USE flags for x11-terms/kitty Fast, feature-rich, GPU-based terminal
emerge --ask x11-terms/kitty
Kitty will generally be launched from an on screen menu or keyboard shortcut in a user's graphical environment.
Kitty may be launched from a shell under X11.
Usage: kitty [options] [program-to-run ...] Run the kitty terminal emulator. You can also specify the program to run inside kitty as normal arguments following the options. For example: kitty sh -c "echo hello, world. Press ENTER to quit; read" For comprehensive documentation for kitty, please see: https://sw.kovidgoyal.net/kitty/ Options: --class=CLS Set the class part of the WM_CLASS window property. On Wayland, it sets the app id. Default: kitty --name=NAME Set the name part of the WM_CLASS property (defaults to using the value from --class) --title, -T=TITLE Set the window title. This will override any title set by the program running inside kitty. So only use this if you are running a program that does not set titles. If combined with --session the title will be used for all windows created by the session, that do not set their own titles. --config, -c=CONFIG Specify a path to the configuration file(s) to use. All configuration files are merged onto the builtin kitty.conf, overriding the builtin values. This option can be specified multiple times to read multiple configuration files in sequence, which are merged. Use the special value NONE to not load a config file. If this option is not specified, config files are searched for in the order: $XDG_CONFIG_HOME/kitty/kitty.conf, ~/.config/kitty/kitty.conf, $XDG_CONFIG_DIRS/kitty/kitty.conf. The first one that exists is used as the config file. If the environment variable KITTY_CONFIG_DIRECTORY is specified, that directory is always used and the above searching does not happen. If /etc/xdg/kitty/kitty.conf exists it is merged before (i.e. with lower priority) than any user config files. It can be used to specify system-wide defaults for all users. --override, -o=OVERRIDE Override individual configuration options, can be specified multiple times. Syntax: name=value. For example: -o font_size=20 --directory, -d=DIRECTORY Change to the specified directory when launching Default: . --detach Detach from the controlling terminal, if any --session=SESSION Path to a file containing the startup session (tabs, windows, layout, programs). Use - to read from STDIN. See the README file for details and an example. --watcher, -w=WATCHER Path to a python file. Appropriately named functions in this file will be called for various events, such as when the window is resized, focused or closed. See the section on watchers in the launch command documentation https://sw.kovidgoyal.net/kitty/launch.html. Relative paths are resolved relative to the kitty config directory. Note that this watcher will be added only to all initially created windows, not new windows created after startup. --hold Remain open after child process exits. Note that this only affects the first window. You can quit by either using the close window shortcut or Ctrl+d. --single-instance, -1 If specified only a single instance of kitty will run. New invocations will instead create a new top-level window in the existing kitty instance. This allows kitty to share a single sprite cache on the GPU and also reduces startup time. You can also have separate groups of kitty instances by using the --instance-group option --instance-group=INSTANCE_GROUP Used in combination with the --single-instance option. All kitty invocations with the same --instance-group will result in new windows being created in the first kitty instance within that group --wait-for-single-instance-window-close Normally, when using --single-instance, kitty will open a new window in an existing instance and quit immediately. With this option, it will not quit till the newly opened window is closed. Note that if no previous instance is found, then kitty will wait anyway, regardless of this option. --listen-on=LISTEN_ON Tell kitty to listen on the specified address for control messages. For example, --listen-on=unix:/tmp/mykitty or --listen-on=tcp:localhost:12345. On Linux systems, you can also use abstract UNIX sockets, not associated with a file, like this: --listen-on=unix:@mykitty. Environment variables in the setting are expanded and relative paths are resolved with respect to the temporary directory. To control kitty, you can send it commands with kitty @ using the --to option to specify this address. This option will be ignored, unless you set allow_remote_control to yes in kitty.conf. Note that if you run kitty @ within a kitty window, there is no need to specify the --to option as it is read automatically from the environment. For UNIX sockets, this can also be specified in kitty.conf. --start-as=START_AS Control how the initial kitty window is created. Default: normal Choices: normal, minimized, maximized, fullscreen Debugging options: --version, -v The current kitty version --dump-commands Output commands received from child process to stdout --replay-commands=REPLAY_COMMANDS Replay previously dumped commands. Specify the path to a dump file previously created by --dump-commands. You can open a new kitty window to replay the commands with:: kitty sh -c "kitty --replay-commands /path/to/dump/file; read" --dump-bytes=DUMP_BYTES Path to file in which to store the raw bytes received from the child process --debug-gl, --debug-rendering Debug rendering commands. This will cause all OpenGL calls to check for errors instead of ignoring them. Also prints out miscellaneous debug information. Useful when debugging rendering problems --debug-keyboard This option will cause kitty to print out key events as they are received --debug-font-fallback Print out information about the selection of fallback fonts for characters not present in the main font. --debug-config Print out information about the system and kitty configuration. kitty 0.19.3 created by Kovid Goyal
