gradient-temp

A temperature indicator for i3blocks and polybar, colored according to heat.

Installation

Requirements

• awk (POSIX compatible)
• bc
• i3blocks or polybar

Optional

• fonts-font-awesome

Command-line options

Usage: ./gradient-temp [<options>] <command> [<args>]

Display a temperature indicator using lm_sensors for i3blocks or polybar.

Commands:
  query <sensor>            query sensor
  help                      display help

Options:
  -b <type>     set bar type: i3blocks (default) or polybar
  -H            display temperatures in fahrenheit
  -G            disable color gradient
  -c <temp>     override critical temperature
  -m <temp>     override maximum temperature
  -f <font>     set font for text and symbols
  -t <color>    set color when gradient is disabled
  -S <#color>   set gradient start color (hex triplet)
  -E <#color>   set gradient end color (hex triplet)
  -C <symbol>   set celsius symbol
  -F <symbol>   set fahrenheit symbol
  -T <feature>  set temperature subfeature (default: temp1)
  -h            display this help and exit

Guide

Copy the blocklet configuration in the given i3blocks.conf into your i3blocks configuration file, the recommended config is:

[gradient-temp]
label=🌡
markup=pango
command=$SCRIPT_DIR/gradient-temp
interval=10
instance=__REPLACE_ME__

#FONT=FontAwesome
#GRADIENT=true
#FAHRENHEIT=false
#COLOR_TEMP=white
#COLOR_GRADIENT_START=#0000FF
#COLOR_GRADIENT_END=#FF0000
#SYMBOL_C=℃
#SYMBOL_F=℉
#OVERRIDE_CRIT_TEMP=90
#OVERRIDE_MAX_TEMP=100

Set the instance variable to the sensor to monitor, see sensors -u.

Polybar Configuration

For polybar, add the following to your polybar config file:

[module/temperature]
type = custom/script
exec = /path/to/gradient-temp query __REPLACE_ME__
interval = 10
format-prefix = "🌡 "
format-prefix-foreground = ${colors.foreground-alt}

# Optional: Set bar type to polybar
# BAR_TYPE=polybar

# Optional configuration variables:
# GRADIENT=true
# FAHRENHEIT=false
# COLOR_TEMP=white
# COLOR_GRADIENT_START=#0000FF
# COLOR_GRADIENT_END=#FF0000
# SYMBOL_C=°C  (HTML entities like ℃ are automatically converted for polybar)
# SYMBOL_F=°F  (HTML entities like ℉ are automatically converted for polybar)
# OVERRIDE_CRIT_TEMP=90
# OVERRIDE_MAX_TEMP=100

Or use environment variables in your polybar config:

[module/temperature]
type = custom/script
exec = BAR_TYPE=polybar /path/to/gradient-temp query __REPLACE_ME__
interval = 10

Replace __REPLACE_ME__ with the sensor to monitor (see sensors -u).

Customization

The following can be set in your i3blocks.conf in newer versions if i3blocks, in older versions (<= 1.4-4) you can customize using the program options. The following are configurable:

Variable	Type	Option	Description
BAR_TYPE	string	-b <type>	Bar type: i3blocks (default) or polybar
FONT	string	-f <font>	Font for text and symbols (i3blocks only)
SENSOR	string	-s <sensor>	The sensor to read
GRADIENT	boolean	-G	Whether or not to use the color gradient
FAHRENHEIT	boolean	-H	Whether or not to use fahrenheit
COLOR_TEMP	string	-t <color>	Color of text when not using the color gradient
COLOR_GRADIENT_START	string	-S <#color>	Start color for gradient; Must be a hex triplet prefixed with #
COLOR_GRADIENT_END	string	-E <#color>	End color for gradient; Must be a hex triplet prefixed with #
SYMBOL_C	string	-C <symbol>	Symbol for celsius
SYMBOL_F	string	-F <symbol>	Symbol for fahrenheit
OVERRIDE_CRIT_TEMP	float	-c <temp>	Override critical temperature
OVERRIDE_MAX_TEMP	float	-m <temp>	Override maximum temperature
