#: Fonts {{{

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

    # font_family      monospace
    # font_family      Courier
    # font_family      DejaVu
    # font_family      Droid Sans
    # font_family      Fira Code
    # font_family      FreeMono
    font_family      Nimbus
    # font_family      Source Code Pro
    bold_font        auto
    italic_font      auto
    bold_italic_font auto

    font_size 9.3
    map alt+shift+equal change_font_size all +0.3
    map alt+shift+minus change_font_size all -0.3
    map alt+shift+backspace change_font_size all 0

    adjust_line_height  3
    adjust_column_width 0
    # adjust_column_width -3

#: 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 PowerlineSymbols

#: 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

    disable_ligatures never

#: Choose how you want to handle multi-character ligatures. The
#: default is to always render them.  You can tell kitty to not render
#: them when the cursor is over them by using cursor to make editing
#: easier, or have kitty never render them at all by using always, if
#: you don't like them. The ligature strategy can be set per-window
#: either using the kitty remote control facility or by defining
#: shortcuts for it in kitty.conf, for example::

#:     map alt+1 disable_ligatures_in active always
#:     map alt+2 disable_ligatures_in all never
#:     map alt+3 disable_ligatures_in tab cursor

    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
    # cursor #00ffee
    cursor #ff0000

#: Default cursor color

    # cursor_text_color #333333
    # cursor_text_color #888888
    cursor_text_color background

#: 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
    cursor_shape beam
    # cursor_shape underline

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

    cursor_blink_interval 0.2

#: The interval (in seconds) at which to blink the cursor. Set to zero
#: to disable blinking. Negative values mean use system default. Note
#: that numbers smaller than repaint_delay will be limited to
#: repaint_delay.

    cursor_stop_blinking_after 1

#: Stop blinking cursor after the specified number of seconds of
#: keyboard inactivity.  Set to zero to never stop blinking.

#: }}}

#: Scrollback {{{

    scrollback_lines 200000

#: Number of lines of history to keep in memory for scrolling back.
#: Memory is allocated on demand. Negative numbers are (effectively)
#: infinite scrollback. Note that using very large scrollback is not
#: recommended as it can slow down resizing of the terminal and also
#: use large amounts of RAM.

    # scrollback_pager less -N +?  --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
    # scrollback_pager less  +?  --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
    # scrollback_pager less -N +?─ +N --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
    scrollback_pager less -N +?- +N --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.

    scrollback_pager_history_size 0

#: 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 one character in 4 bytes, so approximatively
#: 2500 lines per megabyte at 100 chars per line. A value of zero or
#: less disables this feature. The maximum allowed size is 4GB.

    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.

    touch_scroll_multiplier 1.0

#: Modify the amount scrolled by a touchpad. Note this is only used
#: for high precision scrolling devices on platforms such as macOS and
#: Wayland. Use negative numbers to change scroll direction.

#: }}}

#: Mouse {{{

    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.
#: Set to a negative value to hide the mouse cursor immediately when
#: typing text. Disabled by default on macOS as getting it to work
#: robustly with the ever-changing sea of bugs that is Cocoa is too
#: much effort.

    url_color #ff1122
    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 or a private buffer on select. With this set to
#: clipboard, simply selecting text with the mouse will cause the text
#: to be copied to clipboard. Useful on platforms such as macOS that
#: do not have the concept of primary selections. You can instead
#: specify a name such as a1 to copy to a private kitty buffer
#: instead. Map a shortcut with the paste_from_buffer action to paste
#: from this private buffer. For example::

#:     map cmd+shift+v paste_from_buffer a1

#: Note that copying to the clipboard is a security risk, as all
#: programs, including websites open in your browser can read the
#: contents of the system clipboard.

    strip_trailing_spaces smart

#: Remove spaces at the end of lines when copying to clipboard. A
#: value of smart will do it when using normal selections, but not
#: rectangle selections. always will always do it.

    rectangle_select_modifiers ctrl+alt

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

    terminal_select_modifiers shift

#: The modifiers to override mouse selection even when a terminal
#: application has grabbed the mouse

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

mark1_foreground red
mark1_background yellow

mark2_foreground black
mark2_background red

mark3_foreground black
mark3_background green

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

    click_interval -1.0

#: The interval between successive clicks to detect double/triple
#: clicks (in seconds). Negative numbers will use the system default
#: instead, if available, or fallback to 0.5.

    focus_follows_mouse yes

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

    pointer_shape_when_grabbed arrow

#: The shape of the mouse pointer when the program running in the
#: terminal grabs the mouse.

#: }}}

#: 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. Also, to minimize latency when there is pending input to be
#: processed, repaint_delay is ignored.

    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 0.0

#: 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

    command_on_bell none

#: Program to run when a bell occurs.

#: }}}

#: 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 *

#: The enabled window layouts. A comma separated list of layout names.
#: The special value all 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)

    placement_strategy center

#: When the window size is not an exact multiple of the cell size, the
#: cell area of the terminal window will have some extra padding on
#: the sides. You can control how that padding is distributed with
#: this option. Using a value of center means the cell area will be
#: placed centrally. A value of top-left means the padding will be on
#: only the bottom and right edges.

    active_border_color #00ff00

#: The color for the border of the active window. Set this to none to
#: not draw borders around 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).

    hide_window_decorations no

#: Hide the window decorations (title-bar and window borders). Whether
#: this works and exactly what effect it has depends on the window
#: manager/operating system.

    resize_debounce_time 0.1

#: The time (in seconds) to wait before redrawing the screen when a
#: resize event is received. On platforms such as macOS, where the
#: operating system sends events corresponding to the start and end of
#: a resize, this number is ignored.

    resize_draw_strategy static

#: Choose how kitty draws a window while a resize is in progress. A
#: value of static means draw the current window contents, mostly
#: unchanged. A value of scale means draw the current window contents
#: scaled. A value of blank means draw a blank window. A value of size
#: means show the window size in cells.

#: }}}

#: 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 fade

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

    tab_bar_min_tabs 2

#: The minimum number of tabs that must exist before the tab bar is
#: shown

    tab_switch_strategy previous

#: The algorithm to use when switching to a tab when the current tab
#: is closed. The default of previous will switch to the last used
#: tab. A value of left will switch to the tab to the left of the
#: closed tab. A value of last will switch to the right-most tab.

    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.

    tab_title_template {title}

#: A template to render the tab title. The default just renders the
#: title. If you wish to include the tab-index as well, use something
#: like: {index}: {title}. Useful if you have shortcuts mapped for
#: goto_tab N.

    active_tab_foreground   #000
    active_tab_background   #eee
    active_tab_font_style   bold-italic
    inactive_tab_foreground #444
    inactive_tab_background #999
    inactive_tab_font_style normal

#: Tab bar colors and styles

#: }}}

#: Color scheme {{{

    foreground #dddddd
    background #211f20

#: The foreground and background colors

    background_opacity 1.0

#: The opacity of the background. A number between 0 and 1, where 1 is
#: opaque and 0 is fully transparent.  This will only work if
#: supported by the OS (for instance, when using a compositor under
#: X11). Note that it only sets the default background color's
#: opacity. This is so that things like the status bar in vim,
#: powerline prompts, etc. still look good.  But it means that if you
#: use a color theme with a background color in your editor, it will
#: not be rendered as transparent.  Instead you should change the
#: default background color in your kitty config and not use a
#: background color in the editor color scheme. Or use the escape
#: codes to set the terminals default colors in a shell script to
#: launch your editor.  Be aware that using a value less than 1.0 is a
#: (possibly significant) performance hit.  If you want to dynamically
#: change transparency of windows set dynamic_background_opacity to
#: yes (this is off by default as it has a performance cost)

    dynamic_background_opacity no

#: Allow changing of the background_opacity dynamically, using either
#: keyboard shortcuts (increase_background_opacity and
#: decrease_background_opacity) or the remote control facility.

    dim_opacity 0.75

#: How much to dim text that has the DIM/FAINT attribute set. One
#: means no dimming and zero means fully dimmed (i.e. invisible).

    selection_foreground #000000

#: The foreground for text selected with the mouse. A value of none
#: means to leave the color unchanged.

    selection_background #5f676a

#: The background for text selected with the mouse.


#: The 16 terminal colors. There are 8 basic colors, each color has a
#: dull and bright version. You can also set the remaining colors from
#: the 256 color table as color16 to color255.

#: }}}

#: 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 variables
#: VISUAL and EDITOR in that order. 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 socket-only

#: 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. You can chose to either allow any program running
#: within kitty to control it, with yes or only programs that connect
#: to the socket specified with the kitty --listen-on command line
#: option, if you use the value socket-only. The latter is useful if
#: you want to prevent programs running on a remote computer over ssh
#: from controlling kitty.

# 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=${MYVAR1}/${HOME}/b

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

    update_check_interval 0

#: Periodically check if an update to kitty is available. If an update
#: is found a system notification is displayed informing you of the
#: available update. The default is to check every 24 hrs, set to zero
#: to disable.

    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. You can additionally specify no-append to
#: disable kitty's protocol extension for clipboard concatenation. The
#: default is to allow writing to the clipboard and primary selection
#: with concatenation enabled. 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. The TERM variable is used by various programs to get
#: information about the capabilities and behavior of the terminal. If
#: you change it, depending on what programs you run, and how
#: different the terminal you are changing it to is, various things
#: from key-presses, to colors, to various advanced features may not
#: work.

#: }}}

#: OS specific tweaks {{{

    confirm_os_window_close 0
    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
#: hide_window_decorations.

    macos_option_as_alt no

#: 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. You
#: can use the values: left, right, or both to use only the left,
#: right or both Option keys as Alt, instead.

    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.

    macos_thicken_font 0

#: Draw an extra border around the font with the given width, to
#: increase legibility at small font sizes. For example, a value of
#: 0.75 will result in rendering that looks similar to sub-pixel
#: antialiasing at common font sizes.

    macos_traditional_fullscreen no

#: Use the traditional full-screen transition, that is faster, but
#: less pretty.

    macos_show_window_title_in all

#: Show or hide the window title in the macOS window or menu-bar. A
#: value of window will show the title of the currently active window
#: at the top of the macOS window. A value of menubar will show the
#: title of the currently active window in the macOS menu-bar, making
#: use of otherwise wasted space. all will show the title everywhere
#: and none hides the title in the window and the menu-bar.

    macos_custom_beam_cursor no

#: Enable/disable custom mouse cursor for macOS that is easier to see
#: on both light and dark backgrounds. WARNING: this might make your
#: mouse cursor invisible on dual GPU machines.

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

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

#:     # Reset the terminal
#:     map kitty_mod+f9 clear_terminal reset active
#:     # Clear the terminal screen by erasing all contents
#:     map kitty_mod+f10 clear_terminal clear active

#:     map kitty_mod+f11 clear_terminal scrollback active
#:     # Scroll the contents of the screen into the scrollback
#:     map kitty_mod+f12 clear_terminal scroll active

#: If you want to operate on all windows instead of just the current
#: one, use all instead of active.

#: It is also possible to remap Ctrl+L to both scroll the current
#: screen contents into the scrollback buffer and clear the screen,
#: instead of just clearing the screen::

#:     map ctrl+l combine : clear_terminal scroll active : send_text normal,application \x0c


#: 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
