Misc configuration

# How many lines of scrollback you want to retain per tab
scrollback_lines = 3500

# Enable the scrollbar.  This is currently disabled by default.
# It will occupy the right window padding space.
# If right padding is set to 0 then it will be increased
# to a single cell width
enable_scroll_bar = true

# If no `prog` is specified on the command line, use this
# instead of running the user's shell.
# The value is the argument array, with the 0th element being
# the executable to run.  The path will be searched to locate
# this if needed.
# For example, to have `wezterm` always run `top` by default,
# you'd use this:
default_prog = ["top"]

# What to set the TERM variable to
term = "xterm-256color"

# Constrains the rate at which output from a child command is
# processed and applied to the terminal model.
# This acts as a brake in the case of a command spewing a
# ton of output and allows for the UI to remain responsive
# so that you can hit CTRL-C to interrupt it if desired.
# The default value is 200,000 bytes/s.
ratelimit_output_bytes_per_second = 200_000

# Constrains the rate at which the multiplexer server will
# unilaterally push data to the client.
# This helps to avoid saturating the link between the client
# and server.
# Each time the screen is updated as a result of the child
# command outputting data (rather than in response to input
# from the client), the server considers whether to push
# the result to the client.
# That decision is throttled by this configuration value
# which has a default value of 10/s
ratelimit_mux_output_pushes_per_second = 10

# Constrain how often the mux server scans the terminal
# model to compute a diff to send to the mux client.
# The default value is 100/s
ratelimit_mux_output_scans_per_second = 100

# If false, do not try to use a Wayland protocol connection
# when starting the gui frontend, and instead use X11.
# This option is only considered on X11/Wayland systems and
# has no effect on macOS or Windows.
# The default is true.
enable_wayland = true


# Specifies how often a blinking cursor transitions between visible
# and invisible, expressed in milliseconds.
# Setting this to 0 disables blinking.
# Note that this value is approximate due to the way that the system
# event loop schedulers manage timers; non-zero values will be at
# least the interval specified with some degree of slop.
# It is recommended to avoid blinking cursors when on battery power,
# as it is relatively costly to keep re-rendering for the blink!
cursor_blink_rate = 800

# Specifies the default cursor style.  various escape sequences
# can override the default style in different situations (eg:
# an editor can change it depending on the mode), but this value
# controls how the cursor appears when it is reset to default.
# The default is `SteadyBlock`.
# Acceptable values are `SteadyBlock`, `BlinkingBlock`,
# `SteadyUnderline`, `BlinkingUnderline`, `SteadyBar`,
# and `BlinkingBar`.
default_cursor_style = "SteadyBlock"
