Building kitty from source¶
kitty is designed to run from source, for easy hackability. Make sure the following dependencies are installed first.
python >= 3.5
harfbuzz >= 1.5.0
freetype (not needed on macOS)
fontconfig (not needed on macOS)
libcanberra (not needed on macOS)
ImageMagick (optional, needed to use the
kitty icattool to display images in the terminal)
pygments (optional, need for syntax highlighting in
kitty +kitten diff)
gcc or clang
For building on Linux in addition to the above dependencies you might also need to install the
libpython3-dev, if they are not already installed by your distro.
Install and run from source¶
git clone https://github.com/kovidgoyal/kitty && cd kitty
Now build the native code parts of kitty with the following command:
You can run kitty, as:
If that works, you can create a symlink to the launcher in
some other directory on your PATH so that you can run kitty using
Building kitty.app on macOS from source¶
kitty.app unlike the released one does not include its own copy of
python and the other dependencies. So if you ever un-install/upgrade those dependencies
you might have to rebuild the app.
kitty.dmg includes all dependencies, unlike the
kitty.app built above and is built automatically by using the
kitty branch of build-calibre however, that is designed to
run on Linux and is not for the faint of heart.
Apple disallows certain functionality, such as notifications for unsigned applications. If you need this functionality, you can try signing the built kitty.app with a self signed certificate, see for example, here.
Build and run from source with Nix¶
On NixOS or any other Linux or macOS system with the Nix package manager
installed, execute nix-shell to create
the correct environment to build kitty or use
nix-shell --pure instead to
eliminate most of the influence of the outside system, e.g. globally installed
nix-shell will automatically fetch all required dependencies and
make them available in the newly spawned shell.
Then proceed with
make app according to the platform specific instructions above.
Note for Linux/macOS packagers¶
While kitty does use python, it is not a traditional python package, so please do not install it in site-packages. Instead run:
python3 setup.py linux-package
This will install kitty into the directory
linux-package. You can run kitty
linux-package/bin/kitty. All the files needed to run kitty will be in
linux-package/lib/kitty. The terminfo file will be installed into
linux-package/share/terminfo. Simply copy these files into
/usr to install
kitty. In other words,
linux-package is the staging area into which kitty is
installed. You can choose a different staging area, by passing the
You should probably split kitty into two packages,
installs the terminfo file and
kitty that installs the main program.
This allows users to install the terminfo file on servers into which they ssh,
without needing to install all of kitty.
You need a couple of extra dependencies to build linux-package.
tic to compile terminfo files, usually found in the
development package of
ncurses. Also, if you are building from
a git checkout instead of the released source code tarball, you will
sphinx-build from the Sphinx documentation generator.
This applies to creating packages for kitty for macOS package managers such as brew or MacPorts as well.
kitty has its own update check mechanism, if you would like to turn
it off for your package, use
python3 setup.py linux-package --update-check-interval=0
