|
|||
color](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#segment-color-customization)
|
||||
without affecting the icon color.
|
||||
|
||||
The battery segment can also be extended to change the icon automatically depending on the battery level.
|
||||
This will override the default battery icon. In order to do this, you need to define the
|
||||
`POWERLEVEL9k_BATTERY_STAGES` variable.
|
||||
|
||||
| Variable | Default Value | Description |
|
||||
| `POWERLEVEL9K_BATTERY_STAGES`|Unset|A string or array to indicate the stages.|
|
||||
|
||||
If you want to use a string, you can declare the variable as follows:
|
||||
```zsh
|
||||
POWERLEVEL9K_BATTERY_STAGES="▁▂▃▄▅▆▇█"
|
||||
```
|
||||
|
||||
If you require extra spacing after the icon, you will have to set it as an array,
|
||||
since spaces in the string will be used as one of the stages and you will get a
|
||||
missing icon. To do this, declare the variable as follows:
|
||||
```zsh
|
||||
POWERLEVEL9K_BATTERY_STAGES=($'\u2581 ' $'\u2582 ' $'\u2583 ' $'\u2584 ' $'\u2585 ' $'\u2586 ' $'\u2587 ' $'\u2588 ')
|
||||
```
|
||||
|
||||
You can also use a multiple character "icon" if you want a longer battery icon. To do
|
||||
this, declare the variable as follows:
|
||||
```zsh
|
||||
POWERLEVEL9K_BATTERY_STAGES=(
|
||||
$'▏ ▏' $'▎ ▏' $'▍ ▏' $'▌ ▏' $'▋ ▏' $'▊ ▏' $'▉ ▏' $'█ ▏'
|
||||
$'█▏ ▏' $'█▎ ▏' $'█▍ ▏' $'█▌ ▏' $'█▋ ▏' $'█▊ ▏' $'█▉ ▏' $'██ ▏'
|
||||
$'██ ▏' $'██▎ ▏' $'██▍ ▏' $'██▌ ▏' $'██▋ ▏' $'██▊ ▏' $'██▉ ▏' $'███ ▏'
|
||||
$'███ ▏' $'███▎ ▏' $'███▍ ▏' $'███▌ ▏' $'███▋ ▏' $'███▊ ▏' $'███▉ ▏' $'████ ▏'
|
||||
$'████ ▏' $'████▎▏' $'████▍▏' $'████▌▏' $'████▋▏' $'████▊▏' $'████▉▏' $'█████▏' )
|
||||
```
|
||||
|
||||
It is now also possible to change the background of the segment automatically depending on
|
||||
the battery level. This will override the following variables: `POWERLEVEL9K_BATTERY_CHARGING`,
|
||||
`POWERLEVEL9K_BATTERY_CHARGED`, `POWERLEVEL9K_BATTERY_DISCONNECTED`, and `POWERLEVEL9K_BATTERY_LOW_COLOR`.
|
||||
In order to do this, we define a color array (from low to high) as follows:
|
||||
```zsh
|
||||
POWERLEVEL9K_BATTERY_LEVEL_BACKGROUND=(196 202 208 214 220 226 190 154 118 82 46)
|
||||
```
|
||||
|
||||
|Brightness|Possible Array|
|
||||
|Bright Colors|(196 202 208 214 220 226 190 154 118 82 46)|
|
||||
|Normal Colors|(124 130 136 142 148 112 76 40 34 28 22)|
|
||||
|Subdued Colors|( 88 94 100 106 70 34 28 22)|
|
||||
|
||||
Please note the following:
|
||||
* an array declarations start with `(` and end with `)`.
|
||||
* both the icon and background changing levels are automatically calculated, so they can be any length.
