NAME

hinoirisetr — automatic display gamma & temperature adjuster with live config reload and control socket

SYNOPSIS

hinoirisetr [options]

DESCRIPTION

hinoirisetr runs as a daemon that automatically adjusts display gamma and color temperature based on time of day. When launched without arguments:

1. Loads configuration from the default path
2. Applies settings according to local time and config sections
3. Watches for config changes every 5 s
4. Listens on a Unix socket for control commands

Environment variables:

• RUST_LOG - Set log level (e.g., export RUST_LOG=debug)

CONFIGURATION

The config file uses INI-style syntax with sections and key-value pairs. Comments begin with #. Default location:

$XDG_CONFIG_HOME/hinoirisetr.toml
# or ~/.config/hinoirisetr.toml

If not found, the daemon emits a warning and uses built-in defaults. If found, the values sunrise_start, sunrise_end, sunset_start, sunset_end are required.

Global Options

• notification_timeout
  Timeout in milliseconds for desktop notifications.

• gamma_backend
  One of: hyprctl, ddcutil, gammastep, xsct, redshift, none.

• temp_backend
  One of: hyprctl, gammastep, xsct, redshift, none.

Section [gamma]

• day
  Gamma percentage for daytime (0–100).

• night
  Gamma percentage for nighttime (0–100).

Section [temp]

• day
  Color temperature in Kelvin for daytime (1000–20000).

• night
  Color temperature in Kelvin for nighttime (1000–20000).

Section [time]

Interpolation options:

• interpolation_temp
• interpolation_gamma available options: linear, cubic, cubiceaseinout, cosine, exponential

Values in hours (0–23):

• sunset_start
• sunset_end
• sunrise_start
• sunrise_end
