+   <https://stackoverflow.com/questions/27474751/how-can-i-codesign-an-app-without-being-in-the-mac-developer-program/27474942>`_.
+
+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
+<https://nixos.org/guides/nix-pills/developing-with-nix-shell.html>`_ 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
+packages. ``nix-shell`` will automatically fetch all required dependencies and
+make them available in the newly spawned shell.
+
+Then proceed with ``make`` or ``make app`` according to the platform specific instructions above.

 |kitty| is a feature full, cross-platform, *fast*, GPU based terminal emulator.
 To update |kitty|, :doc:`follow the instructions <binary>`.
 
+0.19.3 [2020-12-19]
+-------------------
+
+- Happy holidays to all kitty users!
+
+- A new :doc:`broadcast <kittens/broadcast>` kitten to type in all kitty windows
+  simultaneously (:iss:`1569`)
+
+- Add a new mappable `select_tab` action to choose a tab to switch to even
+  when the tab bar is hidden (:iss:`3115`)
+
+- Allow specifying text formatting in :opt:`tab_title_template` (:iss:`3146`)
+
+- Linux: Read :opt:`font_features` from the FontConfig database as well, so
+  that they can be configured in a single, central location (:pull:`3174`)
+
+- Graphics protocol: Add support for giving individual image placements their
+  own ids and for asking the terminal emulator to assign ids for images. Also
+  allow suppressing responses from the terminal to commands.
+  These are backwards compatible protocol extensions. (:iss:`3133`,
+  :iss:`3163`)
+
+- Distribute extra pixels among all eight-blocks rather than adding them
+  all to the last block (:iss:`3097`)
+
+- Fix drawing of a few sextant characters incorrect (:pull:`3105`)
+

+
+- Preserve lines in the scrollback if a scrolling region is defined that
+  is contiguous with the top of the screen (:iss:`3113`)
+

+
+- Fix one ANSI formatting escape code not being removed from the pager history
+  buffer when piping it as plain text (:iss:`3132`)
+
+- Match the save/restore cursor behavior of other terminals, for the sake of
+  interoperability. This means that doing a DECRC without a prior DECSC is now
+  undefined (:iss:`1264`)
+
+- Fix mapping ``remote_control send-text`` not working (:iss:`3147`)
+
+- Add a ``right`` option for :opt:`tab_switch_strategy` (:pull:`3155`)

+
+- Font independent rendering for braille characters, which ensures they are properly
+  aligned at all font sizes.
+

+  :opt:`window_margin_width` and keeping :opt:`draw_minimal_borders` on
+  (:iss:`3017`)
+
+- Fix a regression in 0.19.0 that broke rendering of one-eight bar unicode
+  characters at very small font sizes (:iss:`3025`)

+- Wayland: Fix a crash under GNOME when using multiple OS windows
+  (:pull:`3066`)
+

+  binaries (:iss:`3063`)
+
+- Allow adding MIME definitions to kitty by placing a ``mime.types`` file in
+  the kitty config directory (:iss:`3056`)
+
+- Dont ignore :option:`--title` when using a session file that defines no

+  :opt:`scrollback_pager_history_size` and it needs to be expanded (:iss:`3011`)
+
+- Fix update available notifications repeating (:pull:`3006`)
+
+
+0.19.0 [2020-10-04]
+-------------------
+
+- Add support for `hyperlinks from terminal programs
+  <https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda>`_.
+  Controlled via :opt:`allow_hyperlinks` (:iss:`68`)
+
+- Add support for easily editing or downloading files over SSH sessions

+- Add a new extensible escape code to allow terminal programs to trigger
+  desktop notifications. See :ref:`desktop_notifications` (:iss:`1474`)

+  if one of the windows has some activity after it was last focused
+  (:iss:`2515`)
+
+- macOS: Switch to using the User Notifications framework for notifications.
+  The current notifications framework has been deprecated in Big Sur. The new
+  framework only allows notifications from signed and notarized applications,
+  so people using kitty from homebrew/source are out of luck. Complain to

+Suppressing responses from the terminal
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are using the graphics protocol from a limited client, such as a shell
+script, it might be useful to avoid having to process responses from the
+terminal. For this, you can use the ``q`` key. Set it to ``1`` to suppress
+``OK`` responses and to ``2`` to suppress failure responses.

+.. versionadded:: 0.19.3
+   The ability to suppress responses (see :doc:`kittens/query_terminal` to query kitty version)
+
+
+Requesting image ids from the terminal
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are writing a program that is going to share the screen with other
+programs and you still want to use image ids, it is not possible to know
+what image ids are free to use. In this case, instead of using the ``i``
+key to specify and image id use the ``I`` key to specify and image number
+instead. These numbers are not unique.
+When creating a new image, even if an existing image has the same number a new
+one is created. And the terminal will reply with the id of the newly created
+image. For example, when creating an image with ``I=13``, the terminal will
+send the response::
+
+    <ESC>_Gi=99,I=13;OK<ESC>\
+
+Here, the value of ``i`` is the id for the newly created image and the value of
+``I`` is the same as was sent in the creation command.
+
+All future commands that refer to images using the image number, such as
+creating placements or deleting images, will act on only the newest image with
+that number. This allows the client program to send a bunch of commands dealing
+with an image by image number without waiting for a response from the terminal
+with the image id. Once such a response is received, the client program should
+use the ``i`` key with the image id for all future communication.
+
+.. note:: Specifying both ``i`` and ``I`` keys in any command is an error. The
+   terminal must reply with an EINVAL error message, unless silenced.

+Hyperlinked grep
+=================
+
+This kitten allows you to search your files using `ripgrep
+<https://www.google.com/search?q=ripgrep>`_ and open the results
+directly in your favorite editor in the terminal, at the line containing
+the search result, simply by clicking on the result you want.
+
+To set it up, first create :file:`~/.config/kitty/open-actions.conf` with the
+following contents:
+
+.. code:: conf
+
+    # Open any file with a fragment in vim, fragments are generated
+    # by the hyperlink_grep kitten and nothing else so far.
+    protocol file
+    fragment_matches [0-9]+

+
+    # Open text files without fragments in the editor
+    protocol file
+    mime text/*
+    action launch --type=overlay ${EDITOR} ${FILE_PATH}
+
+
+Now, run a search with::
+
+    kitty +kitten hyperlinked_grep something
+
+Hold down the :kbd:`ctrl+shift` keys and click on any of the
+result lines, to open the file in vim at the matching line. If
+you use some editor other than vim, you should adjust the
+:file:`open-actions.conf` file accordingly.
+
+Finally, add an alias to your shell's rc files to invoke the kitten as ``hg``::
+
+    alias hg='kitty +kitten hyperlinked_grep'
+
+
+You can now run searches with::
+
+    hg some-search-term
+
+If you want to enable completion, for the kitten, you can delegate completion
+to rg. For that, instead of using an alias create a simple wrapper script named
+:file:`hg` somewhere in your ``PATH``:
+
+.. code-block:: sh
+
+    #!/bin/sh
+    exec kitty +kitten hyperlinked_grep "$@"
+
+Then, for example, for ZSH, add the following to :file:`.zshrc`::

+    compdef _rg hg
+
+To learn more about kitty's powerful framework for customizing URL click

+for the ``Window`` object are: ``as_text(as_ans=False, add_history=False,

+The Splits Layout
+--------------------
+
+This is the most flexible layout. You can create any arrangement of windows
+by splitting exiting windows repeatedly. To best use this layout you should
+define a few extra keybindings in :file:`kitty.conf`::
+
+    map F5 launch --location=hsplit
+    map F6 launch --location=vsplit
+    map F7 layout_action rotate
+
+    map shift+up move_window up
+    map shift+left move_window left
+    map shift+right move_window right
+    map shift+down move_window down
+
+    map ctrl+left neighboring_window left
+    map ctrl+right neighboring_window right
+    map ctrl+up neighboring_window up
+    map ctrl+down neighboring_window down
+
+Now you can create horizontal and vertical splits by using :kbd:`F5` and
+:kbd:`F6`. You can move them around using :kbd:`shift+arrow keys`
+and you can move focus to neighboring windows using :kbd:`ctrl+arrow keys`.
+You can switch an existing split from horizontal to vertical and vice versa
+using :kbd:`F7`. Finally, windows can be resized using :ref:`window_resizing`.
+
+This layout takes one option, ``split_axis`` that controls whether new windows
+are placed into vertical or horizontal splits, by default::

+
+Resizing windows
+------------------
+
+You can resize windows inside layouts. Press :sc:`start_resizing_window` (also
+:kbd:`⌘+r` on macOS) to enter resizing mode and follow the on-screen
+instructions.  In a given window layout only some operations may be possible
+for a particular window. For example, in the Tall layout you can make the first
+window wider/narrower, but not taller/shorter. Note that what you are resizing
+is actually not a window, but a row/column in the layout, all windows in that
+row/column will be resized.
+
+You can also define shortcuts in :file:`kitty.conf` to make the active window
+wider, narrower, taller, or shorter by mapping to the ``resize_window``
+action, for example::
+
+   map ctrl+left resize_window narrower
+   map ctrl+right resize_window wider
+   map ctrl+up resize_window taller
+   map ctrl+down resize_window shorter 3
+
+The ``resize_window`` action has a second, optional argument to control
+the resizing increment (a positive integer that defaults to 1).
+
+
+Some layouts take options to control their behavior. For example, the ``fat``
+and ``tall`` layouts accept the ``bias`` and ``full_size`` options to control
+how the available space is split up.
+To specify the option, in :opt:`kitty.conf <enabled_layouts>` use::
+
+    enabled_layouts tall:bias=70;full_size=2
+
+This will have ``2`` instead of a single tall window, that occupy ``70%``
+instead of ``50%`` of available width. ``bias`` can be any number between 10
+and 90.
+
+Writing a new layout only requires about two hundred lines of code, so if there
+is some layout you want, take a look at one of the existing layouts in the
+`layout <https://github.com/kovidgoyal/kitty/tree/master/kitty/layout>`_

+Customizing the actions taken when clicking on links
+======================================================
+
+|kitty| has support for `terminal hyperlinks <https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda>`_. These
+are generated by many terminal programs, such as ``ls``, ``gcc``, ``systemd``,
+``mdcat``, etc. You can customize exactly what happens when clicking on these hyperlinks
+in |kitty|.
+
+You can tell kitty to take arbitrarily many, complex actions
+when a link is clicked. Let us illustrate with some examples, first. Create
+the file :file:`~/.config/kitty/open-actions.conf` with the following:
+
+.. code:: conf
+
+    # Open any image in the full kitty window by clicking on it
+    protocol file
+    mime image/*
+    action launch --type=overlay kitty +kitten icat --hold ${FILE_PATH}
+
+Now, run ``ls --hyperlink=auto`` in kitty and click on the filename of an
+image, holding down :kbd:`ctrl+shift`. It will be opened over the current
+window. Press any key to close it.
+
+Each entry in :file:`open-actions.conf` consists of one or more
+:ref:`matching_criteria`, such as ``protocol`` and ``mime`` and one or more
+``action`` entries. In the example above kitty uses the :doc:`launch <launch>`
+action which can be used to run external programs. Entries are separated by
+blank lines.
+
+Actions are very powerful, anything that you can map to a key combination in
+`kitty.conf` can be used as an action. You can specify more than one action per
+entry if you like, for example:
+
+
+.. code:: conf
+
+    # Tail a log file (*.log) in a new OS Window and reduce its font size
+    protocol file
+    ext log
+    action launch --title ${FILE} --type=os-window tail -f ${FILE_PATH}
+    action change_font_size current -2
+
+
+In the action specification you can expand environment variables, as shown in
+the examples above. In addition to regular environment variables, there are
+some special variables, documented below:
+
+``URL``
+    The full URL being opened
+
+``FILE_PATH``
+    The path portion of the URL (unquoted)
+
+``FILE``
+    The file portion of the path of the URL (unquoted)
+
+``FRAGMENT``
+    The fragment (unquoted), if any of the URL or the empty string.
+
+.. _matching_criteria:
+
+Matching criteria
+------------------
+
+An entry in :file:`open-actions.conf` must have one or more matching criteria.
+URLs that match all criteria for an entry will trigger that entries' actions.
+Processing stops at the first matching entry, so put more specific matching
+criteria at the start of the list. Entries in the file are separated by blank
+lines. The various available criteria are:
+
+``protocol``
+    A comma separated list of protocols, for example: ``http, https``. If
+    absent, there is no constraint on protocol
+
+``url``
+    A regular expression that must match against the entire (unquoted) URL
+
+``fragment_matches``
+    A regular expression that must match against the fragment (part after #) in
+    the URL
+
+``mime``
+    A comma separated list of MIME types, for example: ``text/*, image/*,
+    application/pdf``. You can add MIME types to kitty by creating the
+    :file:`mime.types` in the kitty configuration directory. Useful if your
+    system MIME database does not have definitions you need. This file is
+    in the standard format of one definition per line, like: ``text/plain rst
+    md``.
+
+``ext``
+    A comma separated list of file extensions, for example: ``jpeg, tar.gz``
+
+``file``
+    A shell glob pattern that must match the filename, for example:
+    ``image-??.png``

+
+Desktop notifications
+---------------------------------
+
+|kitty| implements an extensible escape code (OSC 99) to show desktop
+notifications. It is easy to use from shell scripts and fully extensible to
+show title and body.  Clicking on the notification can optionally focus the
+window it came from, and/or send an escape code back to the application running
+in that window.
+
+The design of the escape code is partially based on the discussion in
+the defunct
+`terminal-wg <https://gitlab.freedesktop.org/terminal-wg/specifications/-/issues/13>`_
+
+The escape code has the form::
+
+    <OSC> 99 ; metadata ; payload <terminator>
+
+Here ``<OSC>`` is :code:`<ESC>]` and ``<terminator>`` is
+:code:`<ESC><backslash>`.  The metadata is a section of colon separated
+:code:`key=value` pairs. Every key must be a single character from the set
+:code:`a-zA-Z` and every value must be a word consisting of characters from
+the set :code:`a-zA-Z0-9-_/\+.,(){}[]*&^%$#@!`~`. The payload must be
+interpreted based on the metadata section. The two semi-colons *must* always be
+present even when no metadata is present.
+
+Before going into details, lets see how one can display a simple, single line
+notification from a shell script::
+
+    printf '\x1b]99;;Hello world\x1b\\'
+
+To show a message with a title and a body::
+
+    printf '\x1b]99;i=1:d=0;Hello world\x1b\\'
+    printf '\x1b]99;i=1:d=1:p=body;This is cool\x1b\\'
+
+The most important key in the metadata is the ``p`` key, it controls how the
+payload is interpreted. A value of ``title`` means the payload is setting the
+title for the notification. A value of ``body`` means it is setting the body,
+and so on, see the table below for full details.
+
+The design of the escape code is fundamentally chunked, this is because
+different terminal emulators have different limits on how large a single escape
+code can be. Chunking is accomplished by the ``i`` and ``d`` keys. The ``i``
+key is the *notification id* which can be any string containing the characters
+``[a-zA-Z0-9_-+.]``. The ``d`` key stands for *done* and
+can only take the values ``0`` and ``1``. A value of ``0`` means the
+notification is not yet done and the terminal emulator should hold off
+displaying it. A value of ``1`` means the notification is done, and should be
+displayed. You can specify the title or body multiple times and the terminal
+emulator will concatenate them, thereby allowing arbitrarily long text
+(terminal emulators are free to impose a sensible limit to avoid
+Denial-of-Service attacks).
+
+Both the ``title`` and ``body`` payloads must be either UTF-8 encoded plain
+text with no embedded escape codes, or UTF-8 text that is base64 encoded, in
+which case there must be an ``e=1`` key in the metadata to indicate the payload
+is base64 encoded.
+
+When the user clicks the notification, a couple of things can happen, the
+terminal emulator can focus the window from which the notification came, and/or
+it can send back an escape code to the application indicating the notification
+was activated. This is controlled by the ``a`` key which takes a comma
+separated set of values, ``report`` and ``focus``. The value ``focus`` means
+focus the window from which the notification was issued and is the default.
+``report`` means send an escape code back to the application. The format of the
+returned escape code is::
+
+    <OSC> 99 ; i=identifier ; <terminator>
+
+The value of ``identifier`` comes from the ``i`` key in the escape code sent by
+the application. If the application sends no identifier, then the terminal
+*must* use ``i=0``. Actions can be preceded by a negative sign to turn them
+off, so for example if you do not want any action, turn off the default
+``focus`` action with::
+
+    a=-focus
+
+Complete specification of all the metadata keys is in the table below. If a
+terminal emulator encounters a key in the metadata it does not understand,
+the key *must* be ignored, to allow for future extensibility of this escape
+code. Similarly if values for known keys are unknown, the terminal emulator
+*should* either ignore the entire escape code or perform a best guess effort
+to display it based on what it does understand.
+
+.. note::
+   It is possible to extend this escape code to allow specifying an icon for
+   the notification, however, given that some platforms, such as macOS, dont
+   allow displaying custom icons on a notification, at all, it was decided to
+   leave it out of the spec for the time being.
+
+   Similarly, features such as scheduled notifications could be added in future
+   revisions.
