Install paths

When using the provided Makefile to install i3blocks-modules, it will do so into the following locations:

What	Install location
i3blocks-modules config file	`~/.config/i3blocks-modules/conf`
i3blocks-modules modules	`~/.local/share/i3blocks-modules/`

Format string

When defining a module in the configuration file, you can either go with default settings or specify a custom format string (-f '...') which can contain text, unicode icons or dynamic placeholder variables. This allows for full customization of each module.

Additionally to a fixed format string, you can also define as many conditional format strings as required for your ouput. Conditional format strings are based on the values of placeholders returned by each module. So when the date module for example returns any date between Saturday and Sunday, you could simply make it display Weekend. Or when the iface module returns that nothing is connected, you could simply hide all output completely. Another useful example would be the battery module which could display different icons depending on wether it is currently charging or discharging.

Placeholders

Placeholders are dynamic variables (the names in curly braces) that can be placed anywhere in your fixed or conditional format string for each of your defined modules to make the look&feel of each module according to your needs. Each module comes with their own set of placeholders giving you various ways for customization. (See Available modules for placeholders).

Additionally to specific placeholder, each module also has color placeholders in case you want to create your own colorized markup output (see -np):

{color}
{color_def}
{color_good}
{color_warn}
{color_crit}
{color_info}

To sum it up briefly, placeholders have three use-cases:

Placeholders can be used in the format argument to format your output.
(e.g.: -f 'Signal: {percent}%')
Placeholders can be checked and according to their value the output will differ
(e.g.: -fe '{status}' '=' 'up' '{iface} {ip} ({ssid} {signal}%)')
Placeholders can be used to determine the status and thus affect the final output color.
(e.g.: -tc '{percent}' '<' 50 or -tc '{date}' '=' '^(Sat|Sun)*')

Threshold and stati

Depending on the status of a module (self-evaluated or custom threshold comparison), the output text will be shown in different colors. There are different ways to determine the final status:

Self evaluation: Some modules are able to evaluate their status independently. E.g.: iface will have a good status if it is up and has an IP assigned or it will have a critical status if it is down or absent.
Argument thresholds: You can specify custom command line arguments with which you can compare the value of placeholders (less than, greater then or a regex comparison). This can be done for good, info, warning and critical states.
Status precedence: Even though the module is in good state it can still show up in a critical state. This is evaluated by the precedence. Precedence is evaluated in the following order (later ones always override previous ones):

good
info
warning
critical

Status colors

Every module can set its own set of colors for available stati

Default
Good status
Info status
Warning status
Critical status

Stati can be set via the following module arguments:

-cd <code>   Default color (hexadecimal color code)
             Default value is: #666666
-cg <code>   Good color (hexadecimal color code)
             Default value is: #88b090
-cw <code>   Warning color (hexadecimal color code)
             Default value is: #ccdc90
-cc <code>   Critical color (hexadecimal color code)
             Default value is: #e89393
-ci <code>   Info color (hexadecimal color code)
             Default value is: #fce94f

Instead of setting the color on each module separately, you can also use the i3blocks-modules configuration file to set it globally in ~/.config/i3blocks-modules/config.

💡 Examples

The following examples show command line calls of the modules (each module is simply a bash script that you can execute on the command line) as well as their corresponding configuration settings. In order to get the desired output on the command line, you will need to set the BLOCK_INSTANCE variable to a meaningful value. This variable corresponds to the instance setting of each module in the configuration file.

Set format string

Use placeholders to specify how the module should output the provided information:

command line:

# Note: set BLOCK_INSTANCE to your wifi interface
$ BLOCK_INSTANCE=wlp3s0 ~/.local/share/i3blocks-modules/wifi -f 'WIFI: {ip} {ssid} ({signal}%)'

~/.config/i3blocks/config:

# Note: Set instance to your wifi interface
# Note: interval specifies how often the module should be updated (in seconds)
#       So in this example, it will be updated every 2 seconds.
[wifi]
command=~/.local/share/i3blocks-modules/wifi -f 'WIFI: {ip} {ssid} ({signal}%)'
instance=wlp3s0
interval=2

Set conditional format string

Imagine you want the output to be dynamic in case the module reports a different state and/or the placeholders will not have any values. In the above case, if your wifi interface is not connected or not present, the module would output something like this: WIFI: (%).

So in order to still give a meaningful output for this case, you will need to set a conditional format.

The following example will output your wifi information if it is available, but if the {status} does not equal up, the it changes the format to WIFI: down

command line:

# Note: set BLOCK_INSTANCE to your wifi interface
$ BLOCK_INSTANCE=wlp3s0 ~/.local/share/i3blocks-modules/wifi \
  -f 'WIFI: {ip} {ssid} ({signal}%)' \
  -fe '{status}' '!=' 'up' 'WIFI: down'

~/.config/i3blocks/config:

# Note: Set instance to your wifi interface
# Note: interval specifies how often the module should be updated (in seconds)
#       So in this example, it will be updated every 2 seconds.
[wifi]
command=~/.local/share/i3blocks-modules/wifi -f 'WIFI: {ip} {ssid} ({signal}%)' -fe '{status}' '!=' 'up' 'WIFI: down'
instance=wlp3s0
interval=2

In the above example you will have different outputs based on whether the Wifi interface is up or not up.

Set thresholds

Thresholds allow you to colorize your output depending on the module state (default, good, warning, critical or info). You will need to tell each module (based on your specified conditions) when it reaches a certain state. The normal behaviour of each module is to run in default state.

1. Colorize date with 'good status' during weekends:

command line:

$ ~/.local/share/i3blocks-modules/date -f " {time}" -t "%a, %d.%m.%Y" -tg '{time}' '=' '^(Sat|Sun).*'

~/.config/i3blocks/config:

[date]
command=~/.local/share/i3blocks-modules/date -f " {time}" -t "%a, %d.%m.%Y" -tg '{time}' '=' '^(Sat|Sun).*'
interval=60

2. Colorize time with warning state after 23 o'clock and between 0 and 3 with critical state:

command line:

$ ~/.local/share/i3blocks-modules/date -f " {time}" -t "%H:%M" -tw '{time}' '=' '^23.*' -tc '{time}' '=' '^0(0|1|2|3).*'

~/.config/i3blocks/config:

[time]
command=~/.local/share/i3blocks-modules/date -f " {time}" -t "%H:%M" -tw '{time}' '=' '^23.*' -tc '{time}' '=' '^0(0|1|2|3).*'
interval=1

🔧 Configuration file

i3blocks configuration

Configuration is done as you would normally do it with i3blocks. The only customization would be to setting the command accordingly. The configuration file is available in ~/.config/i3blocks/config.
