##: Fonts {{{
#
#: kitty has very powerful font management. You can configure
#: individual font faces and even specify special fonts for particular
#: characters.

font_family      VictorMono Nerd Font
#font_family      Victor Mono
#bold_font        Source Code Pro Bold
#italic_font      Source Code Pro Italic
#bold_italic_font Source Code Pro Bold Italic

#: You can specify different fonts for the bold/italic/bold-italic
#: variants. By default they are derived automatically, by the OSes
#: font system. Setting them manually is useful for font families that
#: have many weight variants like Book, Medium, Thick, etc. For
#: example::

#:     font_family      Operator Mono Book
#:     bold_font        Operator Mono Medium
#:     italic_font      Operator Mono Book Italic
#:     bold_italic_font Operator Mono Medium Italic

font_size 16.0

#: Font size (in pts)

# adjust_line_height  0
# adjust_column_width 0

#: Change the size of each character cell kitty renders. You can use
#: either numbers, which are interpreted as pixels or percentages
#: (number followed by %), which are interpreted as percentages of the
#: unmodified values. You can use negative pixels or percentages less
#: than 100% to reduce sizes (but this might cause rendering
#: artifacts).

#symbol_map U+E0A0-U+E0A2,U+E0B0-U+E0B3,U+E0C0-U+E0C8,U+E0CC-U+E0CF,U+E0D0-U+E0D2,U+E0D4,U+F000-U+F2E0 DroidSansM Nerd Font Mono

#: Map the specified unicode codepoints to a particular font. Useful
#: if you need special rendering for some symbols, such as for
#: Powerline. Avoids the need for patched fonts. Each unicode code
#: point is specified in the form U+<code point in hexadecimal>. You
#: can specify multiple code points, separated by commas and ranges
#: separated by hyphens. symbol_map itself can be specified multiple
#: times. Syntax is::

#:     symbol_map codepoints Font Family Name

# box_drawing_scale 0.001, 1, 1.5, 2

#: Change the sizes of the lines used for the box drawing unicode
#: characters These values are in pts. They will be scaled by the
#: monitor DPI to arrive at a pixel value. There must be four values
#: corresponding to thin, normal, thick, and very thick lines.

#: }}}

#: Cursor customization {{{

# cursor #cccccc

#: Default cursor color

# cursor_text_color #111111

#: Choose the color of text under the cursor. If you want it rendered
#: with the background color of the cell underneath instead, use the
#: special keyword: background

# cursor_shape block

#: The cursor shape can be one of (block, beam, underline)

# cursor_blink_interval      0.5
# cursor_stop_blinking_after 15.0

#: The interval (in seconds) at which to blink the cursor. Set to zero
#: to disable blinking. Note that numbers smaller than repaint_delay
#: will be limited to repaint_delay. Stop blinking cursor after the
#: specified number of seconds of keyboard inactivity. Set to zero to
#: never stop blinking.

#: }}}

#: Scrollback {{{

scrollback_lines 10000

#: Separate scrollback history size, used only for browsing the scrollback buffer (in MB). This separate buffer is not available for interactive scrolling but will be piped to the pager program when viewing scrollback buffer in a separate window. The current implementation stores the data in UTF-8, so approximatively 10000 lines per megabyte at 100 chars per line, for pure ASCII text, unformatted text. A value of zero or less disables this feature. The maximum allowed size is 4GB.
scrollback_pager_history_size 20

#: Number of lines of history to keep in memory for scrolling back.
#: Memory is allocated on demand.

# scrollback_pager less --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER

#: Program with which to view scrollback in a new window. The
#: scrollback buffer is passed as STDIN to this program. If you change
#: it, make sure the program you use can handle ANSI escape sequences
#: for colors and text formatting. INPUT_LINE_NUMBER in the command
#: line above will be replaced by an integer representing which line
#: should be at the top of the screen.

# wheel_scroll_multiplier 5.0

#: Modify the amount scrolled by the mouse wheel. Note this is only
#: used for low precision scrolling devices, not for high precision
#: scrolling on platforms such as macOS and Wayland. Use negative
#: numbers to change scroll direction.

#: }}}

#: Mouse {{{

# url_color #0087BD
# url_style curly

#: The color and style for highlighting URLs on mouse-over. url_style
#: can be one of: none, single, double, curly

# open_url_modifiers kitty_mod

#: The modifier keys to press when clicking with the mouse on URLs to
#: open the URL

# open_url_with default

#: The program with which to open URLs that are clicked on. The
#: special value default means to use the operating system's default
#: URL handler.

copy_on_select yes

#: Copy to clipboard on select. With this enabled, simply selecting
#: text with the mouse will cause the text to be copied to clipboard.
#: Useful on platforms such as macOS/Wayland that do not have the
#: concept of primary selections. Note that this is a security risk,
#: as all programs, including websites open in your browser can read
#: the contents of the clipboard.

# rectangle_select_modifiers ctrl+alt

#: The modifiers to use rectangular selection (i.e. to select text in
#: a rectangular block with the mouse)

# select_by_word_characters :@-./_~?&=%+#

#: Characters considered part of a word when double clicking. In
#: addition to these characters any character that is marked as an
#: alpha-numeric character in the unicode database will be matched.

# click_interval 0.5

#: The interval between successive clicks to detect double/triple
#: clicks (in seconds)

# mouse_hide_wait 3.0

#: Hide mouse cursor after the specified number of seconds of the
#: mouse not being used. Set to zero to disable mouse cursor hiding.

# focus_follows_mouse no

#: Set the active window to the window under the mouse when moving the
#: mouse around

#: }}}

#: Performance tuning {{{

# repaint_delay 10

#: Delay (in milliseconds) between screen updates. Decreasing it,
#: increases frames-per-second (FPS) at the cost of more CPU usage.
#: The default value yields ~100 FPS which is more than sufficient for
#: most uses. Note that to actually achieve 100 FPS you have to either
#: set sync_to_monitor to no or use a monitor with a high refresh
#: rate.

# input_delay 3

#: Delay (in milliseconds) before input from the program running in
#: the terminal is processed. Note that decreasing it will increase
#: responsiveness, but also increase CPU usage and might cause flicker
#: in full screen programs that redraw the entire screen on each loop,
#: because kitty is so fast that partial screen updates will be drawn.

# sync_to_monitor yes

#: Sync screen updates to the refresh rate of the monitor. This
#: prevents tearing (https://en.wikipedia.org/wiki/Screen_tearing)
#: when scrolling. However, it limits the rendering speed to the
#: refresh rate of your monitor. With a very high speed mouse/high
#: keyboard repeat rate, you may notice some slight input latency. If
#: so, set this to no.

#: }}}

#: Terminal bell {{{

enable_audio_bell no

#: Enable/disable the audio bell. Useful in environments that require
#: silence.

visual_bell_duration 0.1

#: Visual bell duration. Flash the screen when a bell occurs for the
#: specified number of seconds. Set to zero to disable.

# window_alert_on_bell yes

#: Request window attention on bell. Makes the dock icon bounce on
#: macOS or the taskbar flash on linux.

bell_on_tab yes

#: Show a bell symbol on the tab if a bell occurs in one of the
#: windows in the tab and the window is not the currently focused
#: window

#: }}}

#: Window layout {{{

# remember_window_size  yes
# initial_window_width  640
# initial_window_height 400

#: If enabled, the window size will be remembered so that new
#: instances of kitty will have the same size as the previous
#: instance. If disabled, the window will initially have size
#: configured by initial_window_width/height, in pixels. You can use a
#: suffix of "c" on the width/height values to have them interpreted
#: as number of cells instead of pixels.

enabled_layouts horizontal,vertical,grid

#: The enabled window layouts. A comma separated list of layout names.
#: The special value * means all layouts. The first listed layout will
#: be used as the startup layout. For a list of available layouts, see
#: the https://sw.kovidgoyal.net/kitty/index.html#layouts.

# window_resize_step_cells 2
# window_resize_step_lines 2

#: The step size (in units of cell width/cell height) to use when
#: resizing windows. The cells value is used for horizontal resizing
#: and the lines value for vertical resizing.

# window_border_width 1.0

#: The width (in pts) of window borders. Will be rounded to the
#: nearest number of pixels based on screen resolution. Note that
#: borders are displayed only when more than one window is visible.
#: They are meant to separate multiple windows.

# draw_minimal_borders yes

#: Draw only the minimum borders needed. This means that only the
#: minimum needed borders for inactive windows are drawn. That is only
#: the borders that separate the inactive window from a neighbor. Note
#: that setting a non-zero window margin overrides this and causes all
#: borders to be drawn.

# window_margin_width 0.0

#: The window margin (in pts) (blank area outside the border)

# single_window_margin_width -1000.0

#: The window margin (in pts) to use when only a single window is
#: visible. Negative values will cause the value of
#: window_margin_width to be used instead.

# window_padding_width 0.0

#: The window padding (in pts) (blank area between the text and the
#: window border)

# active_border_color #00ff00

#: The color for the border of the active window

# inactive_border_color #cccccc

#: The color for the border of inactive windows

# bell_border_color #ff5a00

#: The color for the border of inactive windows in which a bell has
#: occurred

# inactive_text_alpha 1.0

#: Fade the text in inactive windows by the specified amount (a number
#: between zero and one, with zero being fully faded).

#: }}}

#: Tab bar {{{

# tab_bar_edge bottom

#: Which edge to show the tab bar on, top or bottom

# tab_bar_margin_width 0.0

#: The margin to the left and right of the tab bar (in pts)

tab_bar_style separator

#: The tab bar style, can be one of: fade or separator. In the fade
#: style, each tab's edges fade into the background color, in the
#: separator style, tabs are separated by a configurable separator.

# tab_fade 0.25 0.5 0.75 1

#: Control how each tab fades into the background when using fade for
#: the tab_bar_style. Each number is an alpha (between zero and one)
#: that controls how much the corresponding cell fades into the
#: background, with zero being no fade and one being full fade. You
#: can change the number of cells used by adding/removing entries to
#: this list.

# tab_separator " ┇"

#: The separator between tabs in the tab bar when using separator as
#: the tab_bar_style.

active_tab_foreground   #eee8d5
active_tab_background   #586e75
active_tab_font_style   normal
inactive_tab_foreground #586e75
inactive_tab_background #eee8d5
inactive_tab_font_style normal

#: Tab bar colors and styles

#: }}}

#: Color scheme {{{

include ~/.dotfiles/kitty-solarized-light.conf

#: }}}

#: Advanced {{{

# shell .

#: The shell program to execute. The default value of . means to use
#: whatever shell is set as the default shell for the current user.
#: Note that on macOS if you change this, you might need to add
#: --login to ensure that the shell starts in interactive mode and
#: reads its startup rc files.

# editor .

#: The console editor to use when editing the kitty config file or
#: similar tasks. A value of . means to use the environment variable
#: EDITOR. Note that this environment variable has to be set not just
#: in your shell startup scripts but system-wide, otherwise kitty will
#: not see it.

# close_on_child_death no

#: Close the window when the child process (shell) exits. If no (the
#: default), the terminal will remain open when the child exits as
#: long as there are still processes outputting to the terminal (for
#: example disowned or backgrounded processes). If yes, the window
#: will close as soon as the child process exits. Note that setting it
#: to yes means that any background processes still using the terminal
#: can fail silently because their stdout/stderr/stdin no longer work.

allow_remote_control yes

#: Allow other programs to control kitty. If you turn this on other
#: programs can control all aspects of kitty, including sending text
#: to kitty windows, opening new windows, closing windows, reading the
#: content of windows, etc. Note that this even works over ssh
#: connections.

# env

#: Specify environment variables to set in all child processes. Note
#: that environment variables are expanded recursively, so if you
#: use::

#:     env MYVAR1=a
#:     env MYVAR2=${MYVAR}/${HOME}/b

#: The value of MYVAR2 will be a/<path to home directory>/b.

# startup_session none

#: Path to a session file to use for all kitty instances. Can be
#: overridden by using the kitty --session command line option for
#: individual instances. See
#: https://sw.kovidgoyal.net/kitty/index.html#sessions in the kitty
#: documentation for details. Note that relative paths are interpreted
#: with respect to the kitty config directory. Environment variables
#: in the path are expanded.

# clipboard_control write-clipboard write-primary

#: Allow programs running in kitty to read and write from the
#: clipboard. You can control exactly which actions are allowed. The
#: set of possible actions is: write-clipboard read-clipboard write-
#: primary read-primary The default is to allow writing to the
#: clipboard and primary selection. Note that enabling the read
#: functionality is a security risk as it means that any program, even
#: one running on a remote server via SSH can read your clipboard.

# term xterm-kitty

#: The value of the TERM environment variable to set. Changing this
#: can break many terminal programs, only change it if you know what
#: you are doing, not because you read some advice on Stack Overflow
#: to change it.

#: }}}

#: OS specific tweaks {{{

# macos_titlebar_color system

#: Change the color of the kitty window's titlebar on macOS. A value
#: of system means to use the default system color, a value of
#: background means to use the background color of the currently
#: active window and finally you can use an arbitrary color, such as
#: #12af59 or red. WARNING: This option works by using a hack, as
#: there is no proper Cocoa API for it. It sets the background color
#: of the entire window and makes the titlebar transparent. As such it
#: is incompatible with background_opacity. If you want to use both,
#: you are probably better off just hiding the titlebar with
#: macos_hide_titlebar.

macos_hide_titlebar yes

#: Hide the kitty window's title bar on macOS.

# x11_hide_window_decorations no

#: Hide the window decorations (title bar and window borders) on X11
#: and Wayland. Whether this works and exactly what effect it has
#: depends on the window manager, as it is the job of the window
#: manager/compositor to draw window decorations.

# macos_option_as_alt yes

#: Use the option key as an alt key. With this set to no, kitty will
#: use the macOS native Option+Key = unicode character behavior. This
#: will break any Alt+key keyboard shortcuts in your terminal
#: programs, but you can use the macOS unicode input technique.

# macos_hide_from_tasks no

#: Hide the kitty window from running tasks (Option+Tab) on macOS.

# macos_quit_when_last_window_closed no

#: Have kitty quit when all the top-level windows are closed. By
#: default, kitty will stay running, even with no open windows, as is
#: the expected behavior on macOS.

# macos_window_resizable yes

#: Disable this if you want kitty top-level (OS) windows to not be
#: resizable on macOS.

#: }}}

#: Keyboard shortcuts {{{

#: For a list of key names, see: GLFW keys
#: <http://www.glfw.org/docs/latest/group__keys.html>. The name to use
#: is the part after the GLFW_KEY_ prefix. For a list of modifier
#: names, see: GLFW mods
#: <http://www.glfw.org/docs/latest/group__mods.html>

#: On Linux you can also use XKB key names to bind keys that are not
#: supported by GLFW. See XKB keys
#: <https://github.com/xkbcommon/libxkbcommon/blob/master/xkbcommon/xkbcommon-
#: keysyms.h> for a list of key names. The name to use is the part
#: after the XKB_KEY_ prefix. Note that you should only use an XKB key
#: name for keys that are not present in the list of GLFW keys.

#: You can use the special action no_op to unmap a keyboard shortcut
#: that is assigned in the default configuration.

#: You can combine multiple actions to be triggered by a single
#: shortcut, using the syntax below::

#:     map key combine <separator> action1 <separator> action2 <separator> action3 ...

#: For example::

#:     map kitty_mod+e combine : new_window : next_layout

#: this will create a new window and switch to the next available
#: layout

#: You can use multi-key shortcuts using the syntax shown below::

#:     map key1>key2>key3 action

#: For example::

#:     map ctrl+f>2 set_font_size 20

# kitty_mod ctrl+shift

#: The value of kitty_mod is used as the modifier for all default
#: shortcuts, you can change it in your kitty.conf to change the
#: modifiers for all the default shortcuts.

# clear_all_shortcuts no

#: You can have kitty remove all shortcut definition seen up to this
#: point. Useful, for instance, to remove the default shortcuts.

#: Clipboard {{{

# map kitty_mod+c  copy_to_clipboard
map ctrl+y  paste_from_clipboard
# map kitty_mod+s  paste_from_selection
# map shift+insert paste_from_selection
# map kitty_mod+o  pass_selection_to_program

#: You can also pass the contents of the current selection to any
#: program using pass_selection_to_program. By default, the system's
#: open program is used, but you can specify your own, for example::

#:     map kitty_mod+o pass_selection_to_program firefox

#: You can pass the current selection to a terminal program running in
#: a new kitty window, by using the @selection placeholder::

#:     map kitty_mod+y new_window less @selection

# map kitty_mod+home      scroll_home
# map kitty_mod+end       scroll_end
# map kitty_mod+h         show_scrollback

#: You can send the contents of the current screen + history buffer as
#: stdin to an arbitrary program using the placeholders @text (which
#: is the plain text) and @ansi (which includes text styling escape
#: codes). For only the current screen, use @screen or @ansi_screen.
#: For example, the following command opens the scrollback buffer in
#: less in a new window::

map ctrl+a>h new_window @ansi less +G -R

#: Window management {{{

map kitty_mod+enter new_window

#: You can open a new window running an arbitrary program, for
#: example::

#:     map kitty_mod+y      new_window mutt

#: You can open a new window with the current working directory set to
#: the working directory of the current window using::

#:     map ctrl+alt+enter    new_window_with_cwd

#: You can open a new window that is allowed to control kitty via the
#: kitty remote control facility by prefixing the command line with @.
#: Any programs running in that window will be allowed to control
#: kitty. For example::

#:     map ctrl+enter new_window @ some_program

map kitty_mod+s new_tab @text /home/sven/.dotfiles/bin/term-copyout

# map kitty_mod+e kitten hints

#: Open a currently visible URL using the keyboard. The program used
#: to open the URL is specified in open_url_with.

# map kitty_mod+p>f kitten hints --type path --program -

#: Select a path/filename and insert it into the terminal. Useful, for
#: instance to run git commands on a filename output from a previous
#: git command.

# map kitty_mod+p>shift+f kitten hints --type path

#: Select a path/filename and open it with the default open program.

# map kitty_mod+p>l kitten hints --type line --program -

# map kitty_mod+u      kitten unicode_input
# map kitty_mod+f2     edit_config_file
# map kitty_mod+escape kitty_shell window

#: Open the kitty shell in a new window/tab/overlay/os_window to
#: control kitty using commands.

# map kitty_mod+a>m    set_background_opacity +0.1
# map kitty_mod+a>l    set_background_opacity -0.1
# map kitty_mod+a>1    set_background_opacity 1
# map kitty_mod+a>d    set_background_opacity default
# map kitty_mod+delete clear_terminal reset active

#: You can create shortcuts to clear/reset the terminal. For example::

#:     map kitty_mod+f9 clear_terminal reset active
#:     map kitty_mod+f10 clear_terminal clear active
#:     map kitty_mod+f11 clear_terminal scrollback active

#: You can tell kitty to send arbitrary (UTF-8) encoded text to the
#: client program when pressing specified shortcut keys. For example::

#:     map ctrl+alt+a send_text all Special text

#: This will send "Special text" when you press the ctrl+alt+a key
#: combination.  The text to be sent is a python string literal so you
#: can use escapes like \x1b to send control codes or \u21fb to send
#: unicode characters (or you can just input the unicode characters
#: directly as UTF-8 text). The first argument to send_text is the
#: keyboard modes in which to activate the shortcut. The possible
#: values are normal or application or kitty or a comma separated
#: combination of them.  The special keyword all means all modes. The
#: modes normal and application refer to the DECCKM cursor key mode
#: for terminals, and kitty refers to the special kitty extended
#: keyboard protocol.

#: Another example, that outputs a word and then moves the cursor to
#: the start of the line (same as pressing the Home key)::

#:     map ctrl+alt+a send_text normal Word\x1b[H
#:     map ctrl+alt+a send_text application Word\x1bOH
