## powerlevel9k Theme for ZSH
2015-02-02 01:33:32 +02:00
2015-06-29 02:57:28 +02:00
Powerlevel9k is a theme for ZSH which uses [Powerline
2015-08-06 00:37:06 +02:00
Fonts](https://github.com/powerline/fonts). It can be used with vanilla
2015-07-19 21:40:59 +02:00
ZSH, [Oh-My-Zsh ](https://github.com/robbyrussell/oh-my-zsh ), or
2015-06-29 02:57:28 +02:00
[Prezto ](https://github.com/sorin-ionescu/prezto ), and can also be installed
using [antigen ](https://github.com/zsh-users/antigen ).

There are a number of Powerline ZSH themes available, now. The developers of
2015-07-27 19:45:41 +02:00
this theme focus on four primary goals:
2015-07-19 21:42:00 +02:00
2015-07-19 21:40:59 +02:00
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.
2015-07-27 19:45:41 +02:00
4. Optimize the code for execution speed as much as possible. A snappy terminal
is a happy terminal.

#### 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` . If you don't customize this, the below
configuration is the default:

2015-10-12 23:17:47 +02:00
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status history time)

2015-10-12 23:17:47 +02:00
##### aws
2015-03-30 03:45:49 +02:00
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` :
export AWS_DEFAULT_PROFILE=< profile_name >
2015-10-18 19:55:37 +02:00
##### battery
2015-10-19 01:30:16 +02:00
This segment will display your current battery status (fails gracefully
on systems without a battery). It can be customized in your .zshrc
2015-10-18 19:55:37 +02:00
with the environment variables detailed below with their default values.
POWERLEVEL9K_BATTERY_CHARGING="yellow"
POWERLEVEL9K_BATTERY_CHARGED="green"
POWERLEVEL9K_BATTERY_DISCONNECTED=$DEFAULT_COLOR
POWERLEVEL9K_BATTERY_LOW_THRESHOLD=10
POWERLEVEL9K_BATTERY_LOW_COLOR="red"
In addition to the above it supports standard _FOREGROUND value without affecting the icon color
2015-10-19 04:48:45 +02:00
Supports both OS X and Linux(time remaining requires the acpi program on Linux)
2015-10-18 19:55:37 +02:00
2015-10-12 23:17:47 +02:00
##### context
2015-03-29 20:08:01 +02:00
The `context` segment (user@host string) is conditional. This lets you enable it, but only display
it if you are not your normal user or on a remote host (basically, only print it
2015-03-30 05:01:15 +02:00
when it's likely you need it).
2015-03-29 20:08:01 +02:00
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` :
export DEFAULT_USER=< your username >
2015-10-12 23:17:47 +02:00
##### dir
2015-06-07 01:11:06 +02:00
The `dir` segment shows the current working directory. You can limit the output
to a certain length:
2015-06-07 01:48:02 +02:00
# Limit to the last two folders
POWERLEVEL9K_SHORTEN_DIR_LENGTH=2
2015-06-07 01:11:06 +02:00
2015-07-25 01:34:11 +02:00
To change the way how the current working directory is truncated, just set:
2015-08-05 00:21:09 +02:00
# truncate the middle part
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_middle"
2015-07-25 01:34:11 +02:00
# truncate from right, leaving the first X characters untouched
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
2015-08-05 00:21:09 +02:00
# default behaviour is to truncate whole directories
2015-07-25 01:34:11 +02:00
In each case you have to specify the length you want to shorten the directory
2015-10-17 20:32:59 +02:00
to. So in some cases `POWERLEVEL9K_SHORTEN_DIR_LENGTH` means characters, in
2015-07-25 01:34:11 +02:00
others whole directories.
2015-10-12 23:17:47 +02:00
##### ip
2015-08-29 17:03:44 +02:00
This segment shows you your current internal IP address. It tries to examine
all currently used network interfaces and prints the first address it finds.
In the case that this is not the right IP address you can specify the correct
network interface by setting:
POWERLEVEL9K_IP_INTERFACE="eth0"
2015-10-12 23:26:04 +02:00
##### rspec_stats
2015-10-12 23:17:47 +02:00
See [Unit Test Ratios ](#unit-test-ratios ), below.
##### status
This segment shows the return code of the last command, and the presence of any
background jobs. By default, this segment will always print, but you can
customize it to only print if there is an error or a forked job by setting the
following variable in your `~/.zshrc` .
POWERLEVEL9K_STATUS_VERBOSE=false
2015-10-20 00:37:17 +02:00
##### ram
By default this segment shows you free RAM and used Swap. If you want to show
only one value, you can specify `POWERLEVEL9K_RAM_ELEMENTS` and set it to either
`ram_free` or `swap_used` . Full example:
# Show only used swap:
POWERLEVEL9K_RAM_ELEMENTS=(swap_used)
2015-10-12 23:17:47 +02:00
##### symphony2_tests
See [Unit Test Ratios ](#unit-test-ratios ), below.
##### time
2015-04-03 16:49:54 +02:00
2015-09-19 20:38:55 +02:00
By default the time is show in 'H:M:S' format. If you want to change it,
2015-07-26 23:43:16 +02:00
just set another format in your `~/.zshrc` . As an example, this is a reversed
time format:
2015-04-03 16:49:54 +02:00
2015-07-26 23:43:16 +02:00
# 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:
# Output time, date, and a symbol from the "Awesome Powerline Font" set
2015-07-25 11:27:18 +02:00
POWERLEVEL9K_TIME_FORMAT="%D{%H:%M:%S \uE868 %d.%m.%y}"
2015-04-03 16:49:54 +02:00
2015-10-12 23:17:47 +02:00
##### vcs
2015-03-30 04:54:58 +02:00
By default, the `vcs` segment will provide quite a bit of information. If you
would also like for it to display the current hash / changeset, simply define
2015-03-31 00:57:15 +02:00
`POWERLEVEL9K_SHOW_CHANGESET` in your `~/.zshrc` . If activated, it will show
the first 12 characters of the changeset id. To change the amount of characters,
2015-07-08 00:44:52 +02:00
set `POWERLEVEL9K_CHANGESET_HASH_LENGTH` to any value you want.
2015-03-30 04:54:58 +02:00
2015-03-31 00:57:15 +02:00
# enable the vcs segment in general
2015-03-30 04:54:58 +02:00
POWERLEVEL9K_SHOW_CHANGESET=true
2015-03-31 00:57:15 +02:00
# just show the 6 first characters of changeset
POWERLEVEL9K_CHANGESET_HASH_LENGTH=6
2015-03-30 04:54:58 +02:00
2015-07-10 00:43:10 +02:00
You can also disable the branch icon in your prompt by setting
`POWERLEVEL9K_HIDE_BRANCH_ICON` to `true` :
2015-04-02 01:25:32 +02:00
2015-07-10 00:43:10 +02:00
# Hide the branch icon
POWERLEVEL9K_HIDE_BRANCH_ICON=true
2015-03-30 04:54:58 +02:00
2015-10-12 23:17:47 +02:00
**vcs Symbols**
2015-04-02 01:25:32 +02:00
2015-06-04 04:59:16 +02:00
The `vcs` segment uses various symbols to tell you the state of your repository.
2015-06-06 02:17:35 +02:00
These symbols depend on your installed font and selected `POWERLEVEL9K_MODE`
from the [Installation ](#Installation ) section above.

2015-10-12 23:17:47 +02:00
##### vi_mode
2015-10-18 05:29:07 +02:00
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 ).
2015-10-12 23:17:47 +02:00
2015-10-18 05:29:07 +02:00
If you want to display a string other than "NORMAL" or "INSERT" in `command` and
`insert-mode` , you can do so by setting the following variables in your
`~/.zshrc` :
2015-10-12 23:17:47 +02:00
2015-10-18 05:29:07 +02:00
POWERLEVEL9K_VI_INSERT_MODE_STRING="INSERT"
POWERLEVEL9K_VI_COMMAND_MODE_STRING="NORMAL"
2015-10-16 20:16:31 +02:00
2015-10-12 23:17:47 +02:00
#### Unit Test Ratios
2015-10-12 23:26:04 +02:00
The `symfony2_tests` and `rspec_stats` segments both show a ratio of "real"
2015-10-12 23:17:47 +02:00
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.
