Update patches from https://github.com/KittyPatch/kitty to work on current kitty

Note that we loose unicode char matching for --type=word because of
https://github.com/dlclark/regexp2/issues/65 and of course user regexps
cant use \p{N} escapes any more. Hopefully regexp2 will add support for
these soon-ish. IMO lookaround is more important than \p.

Fixes #6265

-
-|kitty| has its defaults chosen to be suitable for a standalone distributable.
-If you are packaging it a few of these might need to be changed.
-
-update-checking
-   |kitty| has its own update check mechanism, if you would like to turn
-   it off for your package, use::
-
-       ./setup.py linux-package --update-check-interval=0
-
-shell-integration
-   |kitty| by default injects its :ref:`shell_integration` code into the user's
-   shell using environment variables or (for bash only) modifying
-   the user's :file:`~/.bashrc` file.
-   For a package, it might make more sense to distribute the shell
-   integration scripts into the system-wide shell vendor locations. The
-   shell integration files are found in the :file:`shell-integration`
-   directory. Copy them to the system wide shell vendor locations for each
-   shell, and use::

-       ./setup.py linux-package --shell-integration=enabled\ no-rc

+- unicode_input kitten: Fix a regression in 0.28.0 that caused the order of recent and favorites entries to not be respected (:iss:`6214`)
+
+- unicode_input kitten: Fix a regression in 0.28.0 that caused editing of favorites to sometimes hang
+
+- clipboard kitten: Fix a bug causing the last MIME type available on the clipboard not being recognized when pasting
+
+- Fix regression in 0.28.0 causing color fringing when rendering in transparent windows on light backgrounds (:iss:`6209`)
+
+- show_key kitten: In kitty mode show the actual bytes sent by the terminal rather than a re-encoding of the parsed key event
+
+- hints kitten: Fix a regression in 0.28.0 that broke using sub-groups in regexp captures (:iss:`6228`)
+
+- hints kitten: Fix a regression in 0.28.0 that broke using lookahead/lookbehind in regexp captures (:iss:`6265`)
+
+- diff kitten: Fix a regression in 0.28.0 that broke using relative paths as arguments to the kitten (:iss:`6325`)
+
+- Fix re-using the image id of an animated image for a still image causing a crash (:iss:`6244`)
+

+  of script files via MIME type association from programs that unconditionally "open" attachments/downloaded files
+
+- edit-in-kitty: Fix running edit-in-kitty with elevated privileges to edit a restricted file not working (:disc:`6245`)
+

+Copying all data types to the clipboard
+==============================================
+
+There already exists an escape code to allow terminal programs to
+read/write plain text data from the system clipboard, *OSC 52*.
+kitty introduces a more advanced protocol that supports:
+
+* Copy arbitrary data including images, rich text documents, etc.
+* Allow terminals to ask the user for permission to access the clipboard and
+  report permission denied
+
+The escape code is *OSC 5522*, an extension of *OSC 52*. The basic format
+of the escape code is::
+
+    <OSC>5522;metadata;payload<ST>
+
+Here, *metadata* is a colon separated list of key-value pairs and payload is
+base64 encoded data. :code:`OSC` is :code:`<ESC>[`.
+:code:`ST` is the string terminator, :code:`<ESC>\\`.
+
+Reading data from the system clipboard
+----------------------------------------
+
+To read data from the system clipboard, the escape code is::
+
+    <OSC>5522;type=read;<base 64 encoded space separated list of mime types to read><ST>
+
+For example, to read plain text and PNG data, the payload would be::
+
+    text/plain image/png
+
+encoded as base64. To read from the primary selection instead of the
+clipboard, add the key ``loc=primary`` to the metadata section.
+
+To get the list of MIME types available on the clipboard the payload must be
+just a period (``.``), encoded as base64.
+
+The terminal emulator will reply with a sequence of escape codes of the form::
+
+    <OSC>5522;type=read:status=OK<ST>
+    <OSC>5522;type=read:status=DATA:mime=<base 64 encoded mime type>;<base64 encoded data><ST>
+    <OSC>5522;type=read:status=DATA:mime=<base 64 encoded mime type>;<base64 encoded data><ST>
+    .
+    .
+    .
+    <OSC>5522;type=read:status=DONE<ST>
+
+Here, the ``status=DATA`` packets deliver the data (as base64 encoded bytes)
+associated with each MIME type. The terminal emulator should chunk up the data
+for an individual type. A recommended size for each chunk is 4096 bytes. All
+the chunks for a given type must be transmitted sequentially and only once they
+are done the chunks for the next type, if any, should be sent. The end of data
+is indicated by a ``status=DONE`` packet.
+
+If an error occurs, instead of the opening ``status=OK`` packet the terminal
+must send a ``status=ERRORCODE`` packet. The error code must be one of:
+
+``status=ENOSYS``
+    Sent if the requested clipboard type is not available. For example, primary
+    selection is not available on all systems and ``loc=primary`` was used.
+
+``status=EPERM``
+    Sent if permission to read from the clipboard was denied by the system or
+    the user.
+
+``status=EBUSY``
+    Sent if there is some temporary problem, such as multiple clients in a
+    multiplexer trying to access the clipboard simultaneously.
+
+Terminals should ask the user for permission before allowing a read request.
+However, if a read request only wishes to list the available data types on the
+clipboard, it should be allowed without a permission prompt. This is so that
+the user is not presented with a double permission prompt for reading the
+available MIME types and then reading the actual data.
+
+
+Writing data to the system clipboard
+----------------------------------------
+
+To write data to the system clipboard, the terminal programs sends the
+following sequence of packets::
+
+    <OSC>5522;type=write<ST>
+    <OSC>5522;type=wdata:mime=<base64 encoded mime type>;<base 64 encoded chunk of data for this type><ST>
+    <OSC>5522;type=wdata:mime=<base64 encoded mime type>;<base 64 encoded chunk of data for this type><ST>
+    .
+    .
+    .
+    <OSC>5522;type=wdata<ST>
+
+The final packet with no mime and no data indicates end of transmission. The
+data for every MIME type should be split into chunks of no more than 4096
+bytes. All the chunks for a given MIME type must be sent sequentially, before
+sending chunks for the next MIME type. After the transmission is complete, the
+terminal replies with a single packet indicating success::
+
+    <OSC>5522;type=write:status=DONE<ST>
+
+If an error occurs the terminal can, at any time, send an error packet of the
+form::
+
+    <OSC>5522;type=write:status=ERRORCODE<ST>
+
+Here ``ERRORCODE`` must be one of:
+
+``status=EIO``
+    An I/O error occurred while processing the data
+``status=EINVAL``
+    One of the packets was invalid, usually because of invalid base64 encoding.
+``status=ENOSYS``
+    The client asked to write to the primary selection with (``loc=primary``) and that is not
+    available on the system
+``status=EPERM``
+    Sent if permission to write to the clipboard was denied by the system or
+    the user.
+``status=EBUSY``
+    Sent if there is some temporary problem, such as multiple clients in a
+    multiplexer trying to access the clipboard simultaneously.
+
+Once an error occurs, the terminal must ignore all further OSC 5522 write related packets until it
+sees the start of a new write with a ``type=write`` packet.
+
+The client can send to the primary selection instead of the clipboard by adding
+``loc=primary`` to the initial ``type=write`` packet.
+
+Finally, clients have the ability to *alias* MIME types when sending data to
+the clipboard. To do that, the client must send a ``type=walias`` packet of the
+form::
+
+    <OSC>5522;type=walias;mime=<base64 encoded target MIME type>;<base64 encoded, space separated list of aliases><ST>
+
+The effect of an alias is that the system clipboard will make available all the
+aliased MIME types, with the same data as was transmitted for the target MIME
+type. This saves bandwidth, allowing the client to only transmit one copy of
+the data, but create multiple references to it in the system clipboard. Alias
+packets can be sent anytime after the initial write packet and before the end
+of data packet.
+
+
+Support for terminal multiplexers
+------------------------------------
+
+Since this protocol involves two way communication between the terminal
+emulator and the client program, multiplexers need a way to know which window
+to send responses from the terminal to. In order to make this possible, the
+metadata portion of this escape code includes an optional ``id`` field. If
+present the terminal emulator must send it back unchanged with every response.
+Valid ids must include only characters from the set: ``[a-zA-Z0-9-_+.]``. Any
+other characters must be stripped out from the id by the terminal emulator
+before retransmitting it.
+
+Note that when using a terminal multiplexer it is possible for two different
+programs to tread on each others clipboard requests. This is fundamentally
+unavoidable since the system clipboard is a single global shared resource.
+However, there is an additional complication where responses form this protocol
+could get lost if, for instance, multiple write requests are received
+simultaneously. It is up to well designed multiplexers to ensure that only a
+single request is in flight at a time. The multiplexer can abort requests by
+sending back the ``EBUSY`` error code indicating some other window is trying
+to access the clipboard.

+The number of cells a Unicode character takes up are controlled by the Unicode
+standard. All characters are rendered in a single cell unless the Unicode
 standard says they should be rendered in two cells. When a symbol does not fit,
 it will either be rescaled to be smaller or truncated (depending on how much
 extra space it needs). This is often different from other terminals which just
 let the character overflow into neighboring cells, which is fine if the
 neighboring cell is empty, but looks terrible if it is not.

 Using a color theme with a background color does not work well in vim?
 -----------------------------------------------------------------------
 
-First make sure you have not changed the TERM environment variable, it should
-be ``xterm-kitty``. vim uses *background color erase* even if the terminfo file
-does not contain the ``bce`` capability. This is a bug in vim. You can work around
-it by adding the following to your vimrc::
+Sadly, vim has very poor out-of-the-box detection for modern terminal features.
+Furthermore, it `recently broke detection even more <https://github.com/vim/vim/issues/11729>`__.
+It kind of, but not really, supports terminfo, except it overrides it with its own hard-coded
+values when it feels like it. Worst of all, it has no ability to detect modern
+features not present in terminfo, at all, even security sensitive ones like
+bracketed paste.
 
+Thankfully, probably as a consequence of this lack of detection, vim allows users to
+configure these low level details. So, to make vim work well with any modern
+terminal, including kitty, add the following to your :file:`~/.vimrc`.

-This happens because the |kitty| terminfo files are not available on the server.
-You can ssh in using the following command which will automatically copy the
-terminfo files to the server::
+These issues all have the same root cause: the kitty terminfo files not being
+available. The most common way this happens is SSHing into a computer that does
+not have the kitty terminfo files. The simplest fix for that is running::
 
     kitty +kitten ssh myserver
 
-This ssh kitten takes all the same command line arguments
-as ssh, you can alias it to ssh in your shell's rc files to avoid having to
-type it each time::
+It will automatically copy over the terminfo files and also magically enable
+:doc:`shell integration </shell-integration>` on the remote machine.
 
-    alias ssh="kitty +kitten ssh"
+This :doc:`ssh kitten <kittens/ssh>` takes all the same command line arguments
+as :program:`ssh`, you can alias it to something small in your shell's rc files
+to avoid having to type it each time::
 
-Remember to also setup :ref:`shell_integration` for completion and other
-niceties.
+    alias s="kitty +kitten ssh"
 
-If for some reason that does not work (typically because the server is using a
-non POSIX compliant shell as ``/bin/sh``), you can try using it with ``python``
-instead::
+If this does not work, see :ref:`manual_terminfo_copy` for alternative ways to
+get the kitty terminfo files onto a remote computer.
 
-    kitty +kitten ssh use-python myserver
+The next most common reason for this is if you are running commands as root
+using :program:`sudo` or :program:`su`. These programs often filter the
+:envvar:`TERMINFO` environment variable which is what points to the kitty
+terminfo files.
 
-If that also fails, perhaps because python is not installed on the remote
-server, use the following one-liner instead (it
-is slower as it needs to ssh into the server twice, but will work with most
-servers)::
+First, make sure the :envvar:`TERM` is set to ``xterm-kitty`` in the sudo
+environment. By default, it should be automatically copied over.
 
-    infocmp -a xterm-kitty | ssh myserver tic -x -o \~/.terminfo /dev/stdin
+If you are using a well maintained Linux distribution, it will have a
+``kitty-terminfo`` package that you can simply install to make the kitty
+terminfo files available system-wide. Then the problem will no longer occur.
 
-If you are behind a proxy (like Balabit) that prevents this, you must redirect the
-1st command to a file, copy that to the server and run ``tic`` manually.  If you
-connect to a server, embedded or Android system that doesn't have ``tic``, copy over
-your local file terminfo to the other system as :file:`~/.terminfo/x/xterm-kitty`.
-
-Really, the correct solution for this is to convince the OpenSSH maintainers to
-have ssh do this automatically, if possible, when connecting to a server, so that
-all terminals work transparently.
-
-If the server is running FreeBSD, or another system that relies on termcap
-rather than terminfo, you will need to convert the terminfo file on your local
-machine by running (on local machine with |kitty|)::
-
-    infocmp -C xterm-kitty
-
-The output of this command is the termcap description, which should be appended
-to :file:`/usr/share/misc/termcap` on the remote server. Then run the following
-command to apply your change (on the server)::
-
-    cap_mkdb /usr/share/misc/termcap
-
-
-Keys such as arrow keys, backspace, delete, home/end, etc. do not work when using su or sudo?
--------------------------------------------------------------------------------------------------
-
-Make sure the TERM environment variable, is ``xterm-kitty``.  And either the
-TERMINFO environment variable points to a directory containing :file:`x/xterm-kitty`
-or that file is under :file:`~/.terminfo/x/`.
-
-Note that ``sudo`` might remove TERMINFO.  Then setting it at the shell prompt can
-be too late, because command line editing may not be reinitialized.  In that case
-you can either ask ``sudo`` to set it or if that is not supported, insert an ``env``
-command before starting the shell, or, if not possible, after sudo start another
-Shell providing the right terminfo path::
-
-    sudo … TERMINFO=$HOME/.terminfo bash -i
-    sudo … env TERMINFO=$HOME/.terminfo bash -i
-    TERMINFO=/home/ORIGINALUSER/.terminfo exec bash -i
-
-You can configure sudo to preserve TERMINFO by running ``sudo
-visudo`` and adding the following line::
+Alternately, you can configure :program:`sudo` to preserve :envvar:`TERMINFO`
+by running ``sudo visudo`` and adding the following line::
 
     Defaults env_keep += "TERM TERMINFO"
 
+If none of these are suitable for you, you can run sudo as follows::
+
+    sudo TERMINFO="$TERMINFO" -s -H
+
+This will start a new root shell with the correct :envvar:`TERMINFO` value from your
+current environment copied over.
+
 If you have double width characters in your prompt, you may also need to
 explicitly set a UTF-8 locale, like::
 
     export LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8
 
 
+I cannot use the key combination X in program Y?
+-------------------------------------------------------
+
+First, run::
+
+    kitty +kitten show_key -m kitty
+
+Press the key combination X. If the kitten reports the key press
+that means kitty is correctly sending the key press to terminal programs.
+You need to report the issue to the developer of the terminal program. Most
+likely they have not added support for :doc:`/keyboard-protocol`.

+
+Unicode placeholders
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 0.28.0
+   Support for image display via Unicode placeholders
+
+You can also use a special Unicode character ``U+10EEEE`` as a placeholder for
+an image. This approach is less flexible, but it allows using images inside
+any host application that supports Unicode and foreground colors (tmux, vim, weechat, etc.)
+and has a way to pass escape codes through to the underlying terminal.
+
+The central idea is that we use a single *Private Use* Unicode character as a
+*placeholder* to indicate to the terminal that an image is supposed to be
+displayed at that cell. Since this character is just normal text, Unicode aware
+application will move it around as needed when they redraw their screens,
+thereby automatically moving the displayed image as well, even though they know
+nothing about the graphics protocol. So an image is first created using the
+normal graphics protocol escape codes (albeit in quiet mode (``q=2``) so that there are
+no responses from the terminal that could confuse the host application). Then,
+the actual image is displayed by getting the host application to emit normal
+text consisting of ``U+10EEEE`` and various diacritics (Unicode combining
+characters) and colors.
+
+To use it, first create an image as you would normally with the graphics
+protocol with (``q=2``), but do not create a placement for it, that is, do not
+display it. Then, create a *virtual image placement* by specifying ``U=1`` and
+the desired number of lines and columns::
+
+    <ESC>_Ga=p,U=1,i=<image_id>,c=<columns>,r=<rows><ESC>\
+
+The creation of the placement need not be a separate escape code, it can be
+combined with ``a=T`` to both transmit and create the virtual placement with a
+single code.
+
+The image will eventually be fit to the specified rectangle, its aspect ratio
+preserved. Finally, the image can be actually displayed by using the
+placeholder character, encoding the image ID in its foreground color. The row
+and column values are specified with diacritics listed in
+:download:`rowcolumn-diacritics.txt <../rowcolumn-diacritics.txt>`.  For
+example, here is how you can print a ``2x2`` placeholder for image ID ``42``:
+
+.. code-block:: sh
+
+    printf "\e[38;5;42m\U10EEEE\U0305\U0305\U10EEEE\U0305\U030D\e[39m\n"
+    printf "\e[38;5;42m\U10EEEE\U030D\U0305\U10EEEE\U030D\U030D\e[39m\n"
+
+Here, ``U+305`` is the diacritic corresponding to the number ``0``
+and ``U+30D`` corresponds to ``1``. So these two commands create the following
+``2x2`` placeholder:
+
+========== ==========
+(0, 0)     (1, 0)
+(1, 0)     (1, 1)
+========== ==========
+
+This will cause the image with ID ``42`` to be displayed in a ``2x2`` grid.
+Ideally, you would print out as many cells as the number of rows and columns
+specified when creating the virtual placement, but in case of a mismatch only
+part of the image will be displayed.
+
+By using only the foreground color for image ID you are limited to either 8-bit IDs in 256 color
+mode or 24-bit IDs in true color mode. Since IDs are in a global namespace
+there can easily be collisions. If you need more bits for the image
+ID, you can specify the most significant byte via a third diacritic. For
+example, this is the placeholder for the image ID ``33554474 = 42 + (2 << 24)``:
+
+.. code-block:: sh
+
+    printf "\e[38;5;42m\U10EEEE\U0305\U0305\U030E\U10EEEE\U0305\U030D\U030E\n"
+    printf "\e[38;5;42m\U10EEEE\U030D\U0305\U030E\U10EEEE\U030D\U030D\U030E\n"
+
+Here, ``U+30E`` is the diacritic corresponding to the number ``2``.
+
+You can also specify a placement ID using the underline color (if it's omitted
+or zero, the terminal may choose any virtual placement of the given image). The
+background color is interpreted as the background color, visible if the image is
+transparent. Other text attributes are reserved for future use.
+
+Row, column and most significant byte diacritics may also be omitted, in which
+case the placeholder cell will inherit the missing values from the placeholder
+cell to the left, following the algorithm:
+
+- If no diacritics are present, and the previous placeholder cell has the same
+  foreground and underline colors, then the row of the current cell will be the
+  row of the cell to the left, the column will be the column of the cell to the
+  left plus one, and the most significant image ID byte will be the most
+  significant image ID byte of the cell to the left.
+- If only the row diacritic is present, and the previous placeholder cell has
+  the same row and the same foreground and underline colors, then the column of
+  the current cell will be the column of the cell to the left plus one, and the
+  most significant image ID byte will be the most significant image ID byte of
+  the cell to the left.
+- If only the row and column diacritics are present, and the previous
+  placeholder cell has the same row, the same foreground and underline colors,
+  and its column is one less than the current column, then the most significant
+  image ID byte of the current cell will be the most significant image ID byte
+  of the cell to the left.
+
+These rules are applied left-to-right, which allows specifying only row
+diacritics of the first column, i.e. here is a 2 rows by 3 columns placeholder:
+
+.. code-block:: sh
+
+    printf "\e[38;5;42m\U10EEEE\U0305\U10EEEE\U10EEEE\n"
+    printf "\e[38;5;42m\U10EEEE\U030D\U10EEEE\U10EEEE\n"
+
+This will not work for horizontal scrolling and overlapping images since the two
+given rules will fail to guess the missing information. In such cases, the
+terminal may apply other heuristics (but it doesn't have to).
+
+It is important to distinguish between virtual image placements and real images
+displayed on top of Unicode placeholders. Virtual placements are invisible and only play
+the role of prototypes for real images. Virtual placements can be deleted by a
+deletion command only when the `d` key is equal to ``i``, ``I``, ``n`` or ``N``.
+The key values ``a``, ``c``, ``p``, ``q``, ``x``, ``y``, ``z`` and their capital
+variants never affect virtual placements because they do not have a physical
+location on the screen.
+
+Real images displayed on top of Unicode placeholders are not considered
+placements from the protocol perspective. They cannot be manipulated using
+graphics commands, instead they should be moved, deleted, or modified by
+manipulating the underlying Unicode placeholder as normal text.

+
+The ssh kitten can be configured using the :file:`~/.config/kitty/ssh.conf` file
+where you can specify environment variables to set on the remote host and files
+to copy from the local to the remote host. Let's see a quick example:
+
+.. code-block:: conf
+
+   # Copy the files and directories needed to setup some common tools
+   copy .zshrc .vimrc .vim
+   # Setup some environment variables
+   env SOME_VAR=x
+   # COPIED_VAR will have the same value on the remote host as it does locally
+   env COPIED_VAR=_kitty_copy_env_var_
+
+   # Create some per hostname settings
+   hostname someserver-*
+   copy env-files
+   env SOMETHING=else
+
+   hostname someuser@somehost
+   copy --dest=foo/bar some-file
+   copy --glob some/files.*
+
+
+See below for full details on the syntax and options of :file:`ssh.conf`.
+Additionally, you can pass config options on the command line:
+
+.. code-block:: sh
+
+   kitty +kitten ssh --kitten interpreter=python servername
+
+The :code:`--kitten` argument can be specified multiple times, with directives
+from :file:`ssh.conf`. These are merged with :file:`ssh.conf` as if they were
+appended to the end of that file. They apply only to the host being SSHed to by
+this invocation, so any :opt:`hostname <kitten-ssh.hostname>` directives are
+ignored.
+
+.. warning::
+
+   Due to limitations in the design of SSH, any typing you do before the
+   shell prompt appears may be lost. So ideally don't start typing till you see
+   the shell prompt. 😇
+
+
+.. _real_world_ssh_kitten_config:
+
+A real world example
+----------------------
+
+Suppose you often SSH into a production server, and you would like to setup
+your shell and editor there using your custom settings. However, other people
+could SSH in as well and you don't want to clobber their settings. Here is how
+this could be achieved using the ssh kitten with :program:`zsh` and
+:program:`vim` as the shell and editor, respectively:
+
+.. code-block:: conf
+
+   # Have these settings apply to servers in my organization
+   hostname myserver-*
+
+   # Setup zsh to read its files from my-conf/zsh
+   env ZDOTDIR $HOME/my-conf/zsh
+   copy --dest my-conf/zsh/.zshrc .zshrc
+   copy --dest my-conf/zsh/.zshenv .zshenv
+   # If you use other zsh init files add them in a similar manner
+
+   # Setup vim to read its config from my-conf/vim
+   env VIMINIT $HOME/my-conf/vim/vimrc
+   env VIMRUNTIME $HOME/my-conf/vim
+   copy --dest my-conf/vim .vim
+   copy --dest my-conf/vim/vimrc .vimrc
+
+
+How it works
+----------------
+
+The ssh kitten works by having SSH transmit and execute a POSIX sh (or
+:opt:`optionally <kitten-ssh.interpreter>` Python) bootstrap script on the
+remote host using an :opt:`interpreter <kitten-ssh.interpreter>`. This script
+reads setup data over the TTY device, which kitty sends as a Base64 encoded
+compressed tarball. The script extracts it and places the :opt:`files <kitten-ssh.copy>`
+and sets the :opt:`environment variables <kitten-ssh.env>` before finally
+launching the :opt:`login shell <kitten-ssh.login_shell>` with :opt:`shell
+integration <kitten-ssh.shell_integration>` enabled. The data is requested by
+the kitten over the TTY with a random one time password. kitty reads the request
+and if the password matches a password pre-stored in shared memory on the
+localhost by the kitten, the transmission is allowed. If your local
+`OpenSSH <https://www.openssh.com/>`__ version is >= 8.4 then the data is
+transmitted instantly without any roundtrip delay.
+
+.. note::
+
+   When connecting to BSD hosts, it is possible the bootstrap script will fail
+   or run slowly, because the default shells are crippled in various ways.
+   Your best bet is to install Python on the remote, make sure the login shell
+   is something POSIX sh compliant, and use :code:`python` as the
+   :opt:`interpreter <kitten-ssh.interpreter>` in :file:`ssh.conf`.
+
+
+.. note::
+
+   This may or may not work when using terminal multiplexers, depending on
+   whether they passthrough the escape codes and if the values of the
+   environment variables :envvar:`KITTY_PID` and :envvar:`KITTY_WINDOW_ID` are
+   correct in the current session (they can be wrong when connecting to a tmux
+   session running in a different window) and the ssh kitten is run in the
+   currently active multiplexer window.

+
+
+.. _manual_terminfo_copy:
+
+Copying terminfo files manually
+-------------------------------------
+
+Sometimes, the ssh kitten can fail, or maybe you dont like to use it. In such
+cases, the terminfo files can be copied over manually to a server with the
+following one liner::
+
+    infocmp -a xterm-kitty | ssh myserver tic -x -o \~/.terminfo /dev/stdin
+
+If you are behind a proxy (like Balabit) that prevents this, or you are SSHing
+into macOS where the :program:`tic` does not support reading from :file:`STDIN`,
+you must redirect the first command to a file, copy that to the server and run :program:`tic`
+manually. If you connect to a server, embedded, or Android system that doesn't
+have :program:`tic`, copy over your local file terminfo to the other system as
+:file:`~/.terminfo/x/xterm-kitty`.
+
+If the server is running a relatively modern Linux distribution and you have
+root access to it, you could simply install the ``kitty-terminfo`` package on
+the server to make the terminfo files available.
+
+Really, the correct solution for this is to convince the OpenSSH maintainers to
+have :program:`ssh` do this automatically, if possible, when connecting to a
+server, so that all terminals work transparently.
+
+If the server is running FreeBSD, or another system that relies on termcap
+rather than terminfo, you will need to convert the terminfo file on your local
+machine by running (on local machine with |kitty|)::
+
+    infocmp -CrT0 xterm-kitty
+
+The output of this command is the termcap description, which should be appended
+to :file:`/usr/share/misc/termcap` on the remote server. Then run the following
+command to apply your change (on the server)::
+
+    cap_mkdb /usr/share/misc/termcap

+Scripting the opening of files with kitty on macOS
+-------------------------------------------------------

+On macOS you can use :guilabel:`Open With` in Finder or drag and drop files and
+URLs onto the kitty dock icon to open them with kitty. The default actions are:
+
+* Open text files in your editor and images using the icat kitten.
+* Run shell scripts in a shell
+* Open SSH urls using the ssh command
+
+These actions can also be executed from the command line by running::
+
+    kitty +open file_or_url another_url ...
+
+    # macOS only
+    open -a kitty.app file_or_url another_url ...
+
+Since macOS lacks an official interface to set default URL scheme handlers,
+kitty has a command you can use for it. The first argument for is the URL
+scheme, and the second optional argument is the bundle id of the app, which
+defaults to kitty, if not specified. For example:
+
+.. code-block:: sh
+
+    # Set kitty as the handler for ssh:// URLs
+    kitty +runpy 'from kitty.fast_data_types import cocoa_set_url_handler; import sys; cocoa_set_url_handler(*sys.argv[1:]); print("OK")' ssh

+

+
+Encrypted communication
+--------------------------
+
+.. versionadded:: 0.26.0
+
+When using the :opt:`remote_control_password` option communication to the
+terminal is encrypted to keep the password secure. A public key is used from
+the :envvar:`KITTY_PUBLIC_KEY` environment variable. Currently, only one
+encryption protocol is supported. The protocol number is present in
+:envvar:`KITTY_PUBLIC_KEY` as ``1``. The key data in this environment variable
+is :rfc:`Base-85 <1924>` encoded.  The algorithm used is `Elliptic Curve Diffie
+Helman <https://en.wikipedia.org/wiki/Elliptic-curve_Diffie–Hellman>`__ with
+the `X25519 curve <https://en.wikipedia.org/wiki/Curve25519>`__. A time based
+nonce is used to minimise replay attacks. The original JSON command has the
+fields: ``password`` and ``timestamp`` added. The timestamp is the number of
+nanoseconds since the epoch, excluding leap seconds. Commands with a timestamp
+more than 5 minutes from the current time are rejected. The command is then
+encrypted using AES-256-GCM in authenticated encryption mode, with a symmetric
+key that is derived from the ECDH key-pair by running the shared secret through
+SHA-256 hashing, once.  An IV of at least 96 bits of CSPRNG data is used. The
+tag for authenticated encryption **must** be at least 128 bits long.  The tag
+**must** authenticate only the value of the ``encrypted`` field. A new command
+is created and transmitted that contains the fields:
+
+.. code-block:: json
+
+    {
+        "version": "<kitty version>",
+        "iv": "base85 encoded IV",
+        "tag": "base85 encoded AEAD tag",
+        "pubkey": "base85 encoded ECDH public key of sender",
+        "encrypted": "The original command encrypted and base85 encoded"
+    }
+
+Async and streaming requests
+---------------------------------
+
+Some remote control commands require asynchronous communication, that is, the
+response from the terminal can happen after an arbitrary amount of time. For
+example, the :code:`select-window` command requires the user to select a window
+before a response can be sent. Such command must set the field :code:`async`
+in the JSON block above to a random string that serves as a unique id. The
+client can cancel an async request in flight by adding the :code:`cancel_async`
+field to the JSON block. A async response remains in flight until the terminal
+sends a response to the request. Note that cancellation requests dont need to
+be encrypted as users must not be prompted for these and the worst a malicious
+cancellation request can do is prevent another sync request from getting a
+response.
+
+Similar to async requests are *streaming* requests. In these the client has to
+send a large amount of data to the terminal and so the request is split into
+chunks. In every chunk the JSON block must contain the field ``stream`` set to
+``true`` and ``stream_id`` set to a random long string, that should be the same for
+all chunks in a request. End of data is indicated by sending a chunk with no data.

+
+
+Fine grained permissions for remote control
+----------------------------------------------
+
+.. versionadded:: 0.26.0
+
+The :opt:`allow_remote_control` option discussed so far is a blunt
+instrument, granting the ability to any program running on your computer
+or even on remote computers via SSH the ability to use remote control.
+
+You can instead define remote control passwords that can be used to grant
+different levels of control to different places. You can even write your
+own script to decide which remote control requests are allowed. This is
+done using the :opt:`remote_control_password` option in :file:`kitty.conf`.
+Set :opt:`allow_remote_control` to :code:`password` to use this feature.
+Let's see some examples:
+
+.. code-block:: conf
+
+   remote_control_password "control colors" get-colors set-colors
+
+Now, using this password, you can, in scripts run the command::
+
+    kitty @ --password="control colors" set-colors background=red
+
+Any script with access to the password can now change colors in kitty using
+remote control, but only that and nothing else. You can even supply the
+password via the :envvar:`KITTY_RC_PASSWORD` environment variable, or the
+file :file:`~/.config/kitty/rc-password` to avoid having to type it repeatedly.
+See :option:`kitty @ --password-file` and :option:`kitty @ --password-env`.
+
+The :opt:`remote_control_password` can be specified multiple times to create
+different passwords with different capabilities. Run the following to get a
+list of all action names::
+
+    kitty @ --help
+
+You can even use glob patterns to match action names, for example:
+
+.. code-block:: conf
+
+   remote_control_password "control colors" *-colors
+
+If no action names are specified, all actions are allowed.
+
+If ``kitty @`` is run with a password that is not present in
+:file:`kitty.conf`, then kitty will interactively prompt the user to allow or
+disallow the remote control request. The user can choose to allow or disallow
+either just that request or all requests using that password. The user's
+decision is remembered for the duration of that kitty instance.
+
+.. note::
+   For password based authentication to work over SSH, you must pass the
+   :envvar:`KITTY_PUBLIC_KEY` environment variable to the remote host. The
+   :doc:`ssh kitten <kittens/ssh>` does this for you automatically. When
+   using a password, :ref:`rc_crypto` is used to ensure the password
+   is kept secure. This does mean that using password based authentication
+   is slower as the entire command is encrypted before transmission. This
+   can be noticeable when using a command like ``kitty @ set-background-image``
+   which transmits large amounts of image data. Also, the clock on the remote
+   system must match (within a few minutes) the clock on the local system.
+   kitty uses a time based nonce to minimise the potential for replay attacks.
+
+.. _rc_custom_auth:
+
+Customizing authorization with your own program
+____________________________________________________________
+
+If the ability to control access by action names is not fine grained enough,
+you can define your own Python script to examine every remote control command
+and allow/disallow it. To do so create a file in the kitty configuration
+directory, :file:`~/.config/kitty/my_rc_auth.py` and add the following
+to :file:`kitty.conf`:
+
+.. code-block:: conf
+
+    remote_control_password "testing custom auth" my_rc_auth.py
+
+:file:`my_rc_auth.py` should define a :code:`is_cmd_allowed` function
+as shown below:
+
+.. code-block:: py
+
+    def is_cmd_allowed(pcmd, window, from_socket, extra_data):
+        cmd_name = pcmd['cmd']  # the name of the command
+        cmd_payload = pcmd['payload']  # the arguments to the command
+        # examine the cmd_name and cmd_payload and return True to allow
+        # the command or False to disallow it. Return None to have no
+        # effect on the command.
+
+        # The command payload will vary from command to command, see
+        # the rc protocol docs for details. Below is an example of
+        # restricting the launch command to allow only running the
+        # default shell.
+
+        if cmd_name != 'launch':
+            return None
+        if cmd_payload.get('args') or cmd_payload.get('env') or cmd_payload.get('copy_cmdline') or cmd_payload.get('copy_env'):

+environments created by the :link:`Python venv module
+<https://docs.python.org/3/library/venv.html>` or :link:`Conda
+<https://conda.io/>`. In addition, setting the
+env var :envvar:`KITTY_CLONE_SOURCE_CODE` to some shell code will cause that
+code to be run in the cloned window with :code:`eval`. Similarly, setting
+:envvar:`KITTY_CLONE_SOURCE_PATH` to the path of a file will cause that file to
+be sourced in the cloned window. This can be controlled by
+:opt:`clone_source_strategies`.
+
+:command:`clone-in-kitty` works by asking the shell to serialize its internal
+state (mainly CWD and env vars) and this state is transmitted to kitty and
+restored by the shell integration scripts in the cloned window.

+   edit-in-kitty +75 myfile.txt
+
+The :command:`edit-in-kitty` command allows you to seamlessly edit files
+in your default :opt:`editor` in new kitty windows. This works even over
+SSH (if you use the :doc:`ssh kitten <kittens/ssh>`), allowing you
+to easily edit remote files in your local editor with all its bells and
+whistles.
+
+The :command:`edit-in-kitty` command takes almost all the same arguments as the
+:doc:`launch <launch>` command, so you can open a new tab instead or a new OS
+window, etc. Not all arguments are supported, see the discussion in the
+:ref:`clone_shell` section above.
+
+In order to avoid remote code execution, kitty will only execute the configured
+editor and pass the file path to edit to it.
