Powerlevel9k is a theme for ZSH which uses [Powerline
Fonts](https://github.com/powerline/fonts). It can be used with vanilla ZSH or
ZSH frameworks such as [Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh),
[Prezto](https://github.com/sorin-ionescu/prezto),
[Antigen](https://github.com/zsh-users/antigen), and [many
others](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions).

Get more out of your terminal. Be a badass. Impress everyone in 'Screenshot Your
Desktop' threads. Use powerlevel9k.

You can check out some other users' configurations in our wiki: [Show Off Your
Config](https://github.com/bhilburn/powerlevel9k/wiki/Show-Off-Your-Config).

There are a number of Powerline ZSH themes available, now. The developers of
this theme focus on four primary goals:

1. Give users a great out-of-the-box configuration with no additional
   configuration required.
2. Make customization easy for users who do want to tweak their prompt.
3. Provide useful segments that you can enable to make your prompt even more
   effective and helpful. We have prompt segments for everything from unit test
   coverage to your AWS instance.
4. Optimize the code for execution speed as much as possible. A snappy terminal
   is a happy terminal.

Powerlevel9k can be used to create both very useful and beautiful terminal environments:

### Installation
There are two installation steps to go from a vanilla terminal to a PL9k
terminal. Once you are done, you can optionally customize your prompt.

[Installation Instructions](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions)

1. [Install the Powerlevel9k Theme](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions#step-1-install-powerlevel9k)
2. [Install Powerline Fonts](https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions#step-2-install-a-powerline-font)

No configuration is necessary post-installation if you like the default
settings, but there are plenty of segment customization options available if you
are interested.

### Prompt Customization

Be sure to check out the wiki page on the additional prompt customization
options, including color and icon settings: [Stylizing Your Prompt](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt)

#### Customizing Prompt Segments
Customizing your prompt is easy! Select the segments you want to have displayed,
and then assign them to either the left or right prompt by adding the following
variables to your `~/.zshrc`.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_LEFT_PROMPT_ELEMENTS`|`(context dir rbenv vcs)`|Segment list for left prompt|
|`POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS`|`(status root_indicator background_jobs history time)`|Segment list for right prompt|


The table above shows the default values, so if you wanted to set these
variables manually, you would put the following in
your `~/.zshrc`:
```zsh
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status root_indicator background_jobs history time)
```

---------------------------------------------------------------------------------


##### anaconda

This segment shows your active anaconda environment. It relies on either the
`CONDA_ENV_PATH` or the `CONDA_PREFIX` (depending on the `conda` version)
environment variable to be set which happens when you properly `source
activate` an environment.

Special configuration variables:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_ANACONDA_LEFT_DELIMITER`|"("|The left delimiter just before the environment name.|
|`POWERLEVEL9K_ANACONDA_RIGHT_DELIMITER`|")"|The right delimiter just after the environment name.|

Additionally the following segment specific parameters can be used to customize
it: `POWERLEVEL9K_PYTHON_ICON`, `POWERLEVEL9K_ANACONDA_BACKGROUND`, and
`POWERLEVEL9K_ANACONDA_FOREGROUND`.

##### aws

If you would like to display the [current AWS
profile](http://docs.aws.amazon.com/cli/latest/userguide/installing.html), add
the `aws` segment to one of the prompts, and define `AWS_DEFAULT_PROFILE` in
your `~/.zshrc`:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`AWS_DEFAULT_PROFILE`|None|Your AWS profile name|

##### background_jobs

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_BACKGROUND_JOBS_VERBOSE`|`true`|If there is more than one background job, this segment will show the number of jobs. Set this to `false` to turn this feature off.|
`POWERLEVEL9K_BACKGROUND_JOBS_VERBOSE_ALWAYS`|`false`|Always show the jobs count (even if it's zero).|

##### battery

The default settings for this segment will display your current battery status (fails gracefully on
systems without a battery). It is supported on both OSX and Linux (note that it requires `acpi` on Linux).

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_BATTERY_CHARGING`|`"yellow"`|Color to indicate a charging battery.|
|`POWERLEVEL9K_BATTERY_CHARGED`|`"green"`|Color to indicate a charged battery.|
|`POWERLEVEL9K_BATTERY_DISCONNECTED`|`$DEFAULT_COLOR`|Color to indicate absence of battery.|
|`POWERLEVEL9K_BATTERY_LOW_THRESHOLD`|`10`|Threshold to consider battery level critical.|
|`POWERLEVEL9K_BATTERY_LOW_COLOR`|`"red"`|Color to indicate critically low charge level.|
|`POWERLEVEL9K_BATTERY_VERBOSE`|`true`|Display time remaining next to battery level.|

Note that you can [modify the `_FOREGROUND`
color](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#segment-color-customization)
without affecting the icon color.

You can also change the battery 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, which each index indicates a charge level.|

Powerlevel9k will use each index of the string or array as a stage to indicate battery
charge level, progressing from left to right. You can provide any number of
stages. The setting below, for example, provides 8 stages for Powerlevel9k to use.
```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 ')
```

Using the array syntax, you can create stages comprised of multiple characters.
The below setting provides 40 battery stages.
```zsh
POWERLEVEL9K_BATTERY_STAGES=(
   $'▏    ▏' $'▎    ▏' $'▍    ▏' $'▌    ▏' $'▋    ▏' $'▊    ▏' $'▉    ▏' $'█    ▏'
   $'█▏   ▏' $'█▎   ▏' $'█▍   ▏' $'█▌   ▏' $'█▋   ▏' $'█▊   ▏' $'█▉   ▏' $'██   ▏'
   $'██   ▏' $'██▎  ▏' $'██▍  ▏' $'██▌  ▏' $'██▋  ▏' $'██▊  ▏' $'██▉  ▏' $'███  ▏'
   $'███  ▏' $'███▎ ▏' $'███▍ ▏' $'███▌ ▏' $'███▋ ▏' $'███▊ ▏' $'███▉ ▏' $'████ ▏'
   $'████ ▏' $'████▎▏' $'████▍▏' $'████▌▏' $'████▋▏' $'████▊▏' $'████▉▏' $'█████▏' )
```

You can also 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, define a color array, from low to high, as shown below:
```zsh
POWERLEVEL9K_BATTERY_LEVEL_BACKGROUND=(red1 orangered1 darkorange orange1 gold1 yellow1 yellow2 greenyellow chartreuse1 chartreuse2 green1)
```

As with the battery stages, you can use any number of colors and Powerlevel9k
will automatically use all of them appropriately.

Some example settings:
|Brightness|Possible Array|
|Bright Colors|(red1 orangered1 darkorange orange1 gold1 yellow1 yellow2 greenyellow chartreuse1 chartreuse2 green1)|
|Normal Colors|(red3 darkorange3 darkgoldenrod gold3 yellow3 chartreuse2 mediumspringgreen green3 green3 green4 darkgreen)|
|Subdued Colors|(darkred orange4 yellow4 yellow4 chartreuse3 green3 green4 darkgreen)|

##### command_execution_time

Display the time the previous command took to execute if the time is above
`POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD`. The time is formatted to be
"human readable", and so scales the units based on the length of execution time.
If you want more precision, just set the
`POWERLEVEL9K_COMMAND_EXECUTION_TIME_PRECISION` field.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD`|3|Threshold above which to print this segment. Can be set to `0` to always print.|
|`POWERLEVEL9K_COMMAND_EXECUTION_TIME_PRECISION`|2|Number of digits to use in the fractional part of the time value.|

##### custom_command

The `custom_...` segment allows you to turn the output of a custom command into
a prompt segment. As an example, if you wanted to create a custom segment to
display your WiFi signal strength, you might define a custom segment called
`custom_wifi_signal` like this:
```zsh
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="echo signal: \$(nmcli device wifi | grep yes | awk '{print \$8}')"
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_BACKGROUND="blue"
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_FOREGROUND="yellow"
```
If you prefer, you can also define the function in your `.zshrc` rather than
putting it in-line with the variable export, as shown above. Just don't forget
to invoke your function from your segment! Example code that achieves the same
result as the above:
```zsh
zsh_wifi_signal(){
    local signal=$(nmcli device wifi | grep yes | awk '{print $8}')
    local color='%F{yellow}'
    [[ $signal -gt 75 ]] && color='%F{green}'
    [[ $signal -lt 50 ]] && color='%F{red}'
    echo -n "%{$color%}\uf230  $signal%{%f%}" # \uf230 is 
}

POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="zsh_wifi_signal"
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)
```
The command, above, gives you the wireless signal segment shown below:

![signal](http://i.imgur.com/hviMATC.png)

You can define as many custom segments as you wish. If you think you have
a segment that others would find useful, please consider upstreaming it to the
main theme distribution so that everyone can use it!

##### context

The `context` segment (user@host string) is conditional. By default, it will
only print if you are not your 'normal' user (including if you are root), or if
you are SSH'd to a remote host.

To use this feature, make sure the `context` segment is enabled in your prompt
elements (it is by default), and define a `DEFAULT_USER` in your `~/.zshrc`.

You can customize the `context` segment. For example, you can make it to print the
full hostname by setting

```
POWERLEVEL9K_CONTEXT_TEMPLATE="%n@`hostname -f`"
```

You can set the `POWERLEVEL9K_CONTEXT_HOST_DEPTH` variable to change how the
hostname is displayed. See [ZSH Manual](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information)
for details. The default is set to %m which will show the hostname up to the first ‘.’
You can set it to %{N}m where N is an integer to show that many segments of system
hostname. Setting N to a negative integer will show that many segments from the
end of the hostname.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`DEFAULT_USER`|None|Username to consider a "default context" (you can also set `$USER`).|
|`POWERLEVEL9K_ALWAYS_SHOW_CONTEXT`|false|Always show this segment, including $USER and hostname.|
|`POWERLEVEL9K_ALWAYS_SHOW_USER`|false|Always show the username, but conditionalize the hostname.|
|`POWERLEVEL9K_CONTEXT_TEMPLATE`|%n@%m|Default context prompt (username@machine). Refer to the [ZSH Documentation](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html) for all possible expansions, including deeper host depths.|

##### date

The `date` segment shows the current system date.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_DATE_FORMAT`|`%D{%d.%m.%y}`|[ZSH time format](http://zsh.sourceforge.net/Doc/Release Prompt-Expansion.html) to use in this segment.|

##### dir

The `dir` segment shows the current working directory. When using the "Awesome
Powerline" fonts, there are additional glyphs, as well:

| `Compatible` | `Powerline` | `Awesome Powerline` | Situation
|------------|-----------|-------------------|----------------------------
| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12183451/40ec4016-b58f-11e5-9b9e-74e2b2f0b8b3.png) | At the root of your home folder |
| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12369315/8a5d762c-bbf5-11e5-8a20-ca1179f48d6c.png) | Within a subfolder of your home directory |
| None       | None      | ![](https://cloud.githubusercontent.com/assets/1544760/12183452/40f79286-b58f-11e5-9b8c-ed1343a07b08.png) | Outside of your home folder |

To turn off these icons you could set these variables to an empty string.
```zsh
POWERLEVEL9K_HOME_ICON=''
POWERLEVEL9K_HOME_SUB_ICON=''
POWERLEVEL9K_FOLDER_ICON=''
```
You can limit the output to a certain length by truncating long paths.
Customizations available are:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_SHORTEN_DIR_LENGTH`|`2`|If your shorten strategy, below, is entire directories, this field determines how many directories to leave at the end. If your shorten strategy is by character count, this field determines how many characters to allow per directory string.|
|`POWERLEVEL9K_SHORTEN_STRATEGY`|None|How the directory strings should be truncated. See the table below for more informations.|
|`POWERLEVEL9K_SHORTEN_DELIMITER`|`..`|Delimiter to use in truncated strings. This can be any string you choose, including an empty string if you wish to have no delimiter.|

| Strategy Name | Description |
|---------------|-------------|
|Default|Truncate whole directories from left. How many is defined by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`|
|`truncate_middle`|Truncates the middle part of a folder. E.g. you are in a folder named `~/MySuperProjects/AwesomeFiles/BoringOffice`, then it will truncated to `~/MyS..cts/Awe..les/BoringOffice`, if `POWERLEVEL9K_SHORTEN_DIR_LENGTH=3` is also set (controls the amount of characters to be left).|
|`truncate_from_right`|Just leaves the beginning of a folder name untouched. E.g. your folders will be truncated like so: "/ro../Pr../office". How many characters will be untouched is controlled by `POWERLEVEL9K_SHORTEN_DIR_LENGTH`.|
|`truncate_with_package_name`|Search for a `package.json` or `composer.json` and prints the `name` field to abbreviate the directory path. The precedence and/or files could be set by `POWERLEVEL9K_DIR_PACKAGE_FILES=(package.json composer.json)`. If you have [jq](https://stedolan.github.io/jq/) installed, it will dramatically improve the speed of this strategy.|
|`truncate_with_folder_marker`|Search for a file that is specified by `POWERLEVEL9K_SHORTEN_FOLDER_MARKER` and truncate everything before that (if found, otherwise stop on $HOME and ROOT).|
|`truncate_to_unique`|Parse all parent path components and truncate them to the shortest unique length. If you copy & paste the result to a shell, after hitting `TAB` it should expand to the original path unambiguously.|

For example, if you wanted the truncation behavior of the `fish` shell, which
truncates `/usr/share/plasma` to `/u/s/plasma`, you would use the following:
```zsh
POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
POWERLEVEL9K_SHORTEN_DELIMITER=""
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
```
In each case you have to specify the length you want to shorten the directory
to. So in some cases `POWERLEVEL9K_SHORTEN_DIR_LENGTH` means characters, in
others whole directories.

The `truncate_with_package_name` strategy gives your directory path relative to the root of your project.  For example, if you have a project inside `$HOME/projects/my-project` with a `package.json` that looks like:

```json
{
  "name": "my-cool-project"
}
```

The path shown would be `my-cool-project`.  If you navigate to `$HOME/projects/my-project/src`, then the path shown would be `my-cool-project/src`.  Please note that this currently looks for `.git` directory to determine the root of the project.

If you want to customize the directory separator, you could set:
```zsh
# Double quotes are important here!
POWERLEVEL9K_DIR_PATH_SEPARATOR="%F{red} $(print_icon 'LEFT_SUBSEGMENT_SEPARATOR') %F{black}"
```
To omit the first character (usually a slash that gets replaced if you set `POWERLEVEL9K_DIR_PATH_SEPARATOR`),
you could set `POWERLEVEL9K_DIR_OMIT_FIRST_CHARACTER=true`.

You can also customize the leading tilde character when you are in `$HOME` using:
```zsh
# Double quotes are important here!
POWERLEVEL9K_HOME_FOLDER_ABBREVIATION="%F{red} $(print_icon 'HOME_ICON') %F{black}"
```
You can also configure the `dir` segment to show when you are in a directory without write permissions, using the variable below.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_DIR_SHOW_WRITABLE`|`false`|If set to `true` and you are in a directory that you do not have write permissions for, this segment will display a lock icon and enter the `NOT_WRITABLE` state (which can be customized per [our usual process](https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt#segment-color-customization)). Note that this functionality is also available in a separate segment, `dir_writable`.|

If you want to customize the last directory of the path, you can now set `POWERLEVEL9K_DIR_PATH_HIGHLIGHT_FOREGROUND` to a custom color and/or `POWERLEVEL9K_DIR_PATH_HIGHLIGHT_BOLD=true` to display that part in bold.

You can also color the separator separately by setting the color using `POWERLEVEL9K_DIR_PATH_SEPARATOR_FOREGROUND`.

##### disk_usage

The `disk_usage` segment will show the usage level of the partition that your current working directory resides in. It can be configured with the following variables.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|POWERLEVEL9K_DISK_USAGE_ONLY_WARNING|false|Hide the segment except when usage levels have hit warning or critical levels.|
|POWERLEVEL9K_DISK_USAGE_WARNING_LEVEL|90|The usage level that triggers a warning state.|
|POWERLEVEL9K_DISK_USAGE_CRITICAL_LEVEL|95|The usage level that triggers a critical state.|

##### host

The `host` segment will print the hostname.

You can set the `POWERLEVEL9K_HOST_TEMPLATE` variable to change how the hostname
is displayed. See (ZSH Manual)[http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information]
for details. The default is set to `%m` which will show the hostname up to the
first `.`. You can set it to `%{N}m` where N is an integer to show that many
segments of system hostname. Setting `N` to a negative integer will show that many
segments from the end of the hostname.

```
POWERLEVEL9K_HOST_TEMPLATE="%2m"
```

By default, LOCAL hosts will show the host icon and remote hosts will show the SSH icon. You can override them by setting
```
POWERLEVEL9K_HOST_ICON="\uF109 "
POWERLEVEL9K_SSH_ICON="\uF489 "
```


##### ip

This segment tries to examine all currently used network interfaces and prints
the first address it finds.  In the case that this is not the right NIC, you can
specify the correct network interface by setting:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_IP_INTERFACE`|None|The NIC for which you wish to display the IP address. Example: `eth0`.|

##### vpn_ip

This segment tries to extract the VPN related IP addresses from nmcli, based on the NIC type:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_VPN_IP_INTERFACE`|`tun`|The VPN interface.|

##### public_ip

This segment will display your public IP address. There are several methods of obtaining this
information and by default it will try all of them starting with the most efficient. You can
also specify which method you would like it to use. The methods available are dig using opendns,
curl, or wget. The host used for wget and curl is http://ident.me by default but can be set to
another host if you prefer.

If you activate a VPN, the icon for this segment will change to the defined VPN icon.

The public_ip segment will attempt to update your public IP address every 5 minutes by default(also
configurable by the user). If you lose connection your cached IP address will be displayed until
your timeout expires at which point every time your prompt is generated a new attempt will be made.
Until an IP is successfully pulled the value of $POWERLEVEL9K_PUBLIC_IP_NONE will be displayed for
this segment. If this value is empty(the default)and $POWERLEVEL9K_PUBLIC_IP_FILE is empty the
segment will not be displayed.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_PUBLIC_IP_FILE`|'/tmp/p8k_public_ip'|This is the file your public IP is cached in.|
|`POWERLEVEL9K_PUBLIC_IP_HOST`|'http://ident.me'|This is the default host to get your public IP.|
|`POWERLEVEL9K_PUBLIC_IP_TIMEOUT`|300|The amount of time in seconds between refreshing your cached IP.|
|`POWERLEVEL9K_PUBLIC_IP_METHODS`|(dig curl wget)| These methods in that order are used to refresh your IP.|
|`POWERLEVEL9K_PUBLIC_IP_NONE`|None|The string displayed when an IP was not obtained|

##### load

Displays one of your load averages with appropriate state coloring. The thresholds are:
- `0.7 * NUM_CORES <`: critical
- `0.5 * NUM_CORES <`: warning
- `less`: normal

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_LOAD_WHICH`|5|Which average to show. Possible values: 1, 5 or 15|

##### newline

Puts a newline in your prompt so you can continue using segments on the next
line. This allows you to use segments on both lines, unlike
`POWERLEVEL9K_PROMPT_ON_NEWLINE`, which simply separates segments from the
prompt itself.

This only works on the left side.  On the right side it does nothing.

##### rbenv

This segment shows the version of Ruby being used when using `rbenv` to change your current Ruby stack.

It figures out the version being used by taking the output of the `rbenv version-name` command.

* If `rbenv` is not in $PATH, nothing will be shown.
* By default, if the current local Ruby version is the same as the global Ruby version, nothing will be shown. See the configuration variable, below, to modify this behavior.

Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_RBENV_ALWAYS`|'false'|Always show the `rbenv` segment, even if the local version matches the global.|

##### rspec_stats

See [Unit Test Ratios](#unit-test-ratios), below.

##### status

This segment shows the return code of the last command.

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_STATUS_CROSS`|`false`|Set to true if you wish not to show the error code when the last command returned an error and optionally hide this segment when the last command completed successfully by setting `POWERLEVEL9K_STATUS_OK` to false.|
|`POWERLEVEL9K_STATUS_OK`|`true`|Set to true if you wish to show this segment when the last command completed successfully, false to hide it.|
|`POWERLEVEL9K_STATUS_SHOW_PIPESTATUS`|`true`|Set to true if you wish to show the exit status for all piped commands.|
|`POWERLEVEL9K_STATUS_HIDE_SIGNAME`|`false`|Set to true return the raw exit code (`1-255`).  When set to false, values over 128 are shown as `SIGNAME(-n)` (e.g. `KILL(-9)`)|

##### ram

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_RAM_ELEMENTS`|Both|Specify `ram_free` or `swap_used` to only show one or the other rather than both.|

##### symfony2_tests

See [Unit Test Ratios](#unit-test-ratios), below.

##### time

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_TIME_FORMAT`|`'H:M:S'`|ZSH time format to use in this segment.|

As an example, if you wanted a reversed time format, you would use this:
```zsh
# Reversed time format
POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}'
```
If you are using an "Awesome Powerline Font", you can add a time symbol to this
segment, as well:
```zsh
# Output time, date, and a symbol from the "Awesome Powerline Font" set
POWERLEVEL9K_TIME_FORMAT="%D{%H:%M:%S \uE868  %d.%m.%y}"
```
##### user

The `user` segment will print the username.

You can also override the icons by setting:

```
POWERLEVEL9K_USER_ICON="\uF415" # 
POWERLEVEL9K_ROOT_ICON="#"
```

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`DEFAULT_USER`|None|Username to consider a "default context".|
|`POWERLEVEL9K_ALWAYS_SHOW_USER`|`false`|Always print this segment.|
|`POWERLEVEL9K_USER_TEMPLATE`|`%n`|Default username prompt. Refer to the [ZSH Documentation](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html) for all possible expansions|

##### vcs

By default, the `vcs` segment will provide quite a bit of information. Further
customization is provided via:

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_HIDE_BRANCH_ICON`|`false`|Set to `true` to hide the branch icon from the segment.|
|`POWERLEVEL9K_SHOW_CHANGESET`|`false`|Set to `true` to display the hash / changeset in the segment.|
|`POWERLEVEL9K_CHANGESET_HASH_LENGTH`|`12`|How many characters of the hash / changeset to display in the segment.|
|`POWERLEVEL9K_VCS_SHOW_SUBMODULE_DIRTY`|`true`|Set to `false` to not reflect submodule status in the top-level repository prompt.|
|`POWERLEVEL9K_VCS_HIDE_TAGS`|`false`|Set to `true` to stop tags being displayed in the segment.|

|`POWERLEVEL9K_VCS_HG_HOOKS`|`(vcs-detect-changes)`|Layout of the segment for Mercurial repositories.|
|`POWERLEVEL9K_VCS_SVN_HOOKS`|`(vcs-detect-changes svn-detect-changes)`|Layout of the segment for SVN repositories.|


##### vcs symbols

The `vcs` segment uses various symbols to tell you the state of your repository.
These symbols depend on your installed font and selected `POWERLEVEL9K_MODE`
from the [Installation](#Installation) section above.

| `Compatible` | `Powerline` | `Awesome Powerline` | Explanation

##### vi_mode

This segment shows ZSH's current input mode. Note that this is only useful if
you are using the [ZSH Line Editor](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html)
(VI mode).  You can enable this either by `.zshrc` configuration or using a plugin, like
[Oh-My-Zsh's vi-mode plugin](https://github.com/robbyrussell/oh-my-zsh/blob/master/plugins/vi-mode/vi-mode.plugin.zsh).

| Variable | Default Value | Description |
|----------|---------------|-------------|
|`POWERLEVEL9K_VI_INSERT_MODE_STRING`|`"INSERT"`|String to display while in 'Insert' mode.|
|`POWERLEVEL9K_VI_COMMAND_MODE_STRING`|`"NORMAL"`|String to display while in 'Command' mode.|

#### Unit Test Ratios

The `symfony2_tests` and `rspec_stats` segments both show a ratio of "real"
classes vs test classes in your source code. This is just a very simple ratio,
and does not show your code coverage or any sophisticated stats. All this does
is count your source files and test files, and calculate the ratio between them.
Just enough to give you a quick overview about the test situation of the project
you are dealing with.

### Disabling / Enabling Powerlevel9k

You can disable P9k and return to a very basic prompt at any time simply by
calling:

```zsh
$ prompt_powerlevel9k_teardown
```

You can then re-enable it by calling:

```zsh
$ prompt_powerlevel9k_setup
```
