## powerlevel9k Theme for ZSH
|
|
|
|
Powerlevel9k is a theme for ZSH which uses [Powerline
|
|
Fonts](https://github.com/Lokaltog/powerline-fonts), thus giving you the most
|
|
epic terminal styling in the universe.
|
|
|
|
Look like a bad-ass. Impress everyone in 'Screenshot Your Desktop' threads. Use powerlevel9k.
|
|
|
|
Powerlevel9k can be used with vanilla ZSH,
|
|
[Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh), or
|
|
[Prezto](https://github.com/sorin-ionescu/prezto), and can also be installed
|
|
using [antigen](https://github.com/zsh-users/antigen).
|
|
|
|
|
|
In addition to looking amazing, this theme actually provides a lot of useful
|
|
information in configurable prompt segments. Here is an example of what it looks
|
|
like with a normal installation and default settings:

### Features
|
|
|
|
* Supports `git` and `mercurial` repo information through ZSH's `VCS_INFO`:
|
|
* branch / tag name
|
|
* current action status (rebasing, merging, etc.,)
|
|
* being behind / ahead of your remote by some number of commits
|
|
* number of stashes (git only)
|
|
* conditionally shows remote tracking branch if the name differs from local
|
|
* current active bookmark (mercurial only)
|
|
* various working tree statuses (e.g., unstaged, staged, etc.,)
|
|
* Shows return-code of the last command if it is an error code
|
|
* Indicates background jobs with a gear icon
|
|
* Can conditionally display the `user@host` string when needed (e.g., SSH)
|
|
* Provides segment for command history (so you can `$ !<num>` to re-run)
|
|
* Plenty of additional segments to choose from (e.g., AWS, ruby)
|
|
* Can be used as a single or double-lined prompt (see screenshots below)
|
|
* Several built-in color configurations to choose from
|
|
|
|
**If you would like an OMZ theme that provides some of the same features but
|
|
doesn't require Powerline fonts, check out the sister font,
|
|

### Installation
|
|
There are two steps to start using this theme:
|
|
|
|
1. Install the Powerlevel9k theme.
|
|
2. Install Powerline-patched fonts.
|
|
3. [Optional] Configuration
|
|
|
|
To get the most out of Powerlevel9k, you need to install both the theme as well
|
|
as Powerline-patched fonts, if you don't have them installed already. If you
|
|
cannot install Powerline-patched fonts for some reason, follow the instructions
|
|
below for a `compatible` install.
|
|
|
|
No configuration is necessary post-installation if you like the default
|
|
settings, but there is plenty of segment configuration available if you are
|
|
interested.
|
|
|
|
#### Step 1: Install Powerlevel9k
|
|
There are four ways to install and use the Powerlevel9k theme: vanilla ZSH,
|
|
Oh-My-Zsh, Prezto, and antigen. Do one of the following:
|
|
|
|
##### Option 1: Install for Vanilla ZSH
|
|
|
|
If you use just a vanilla ZSH install, simply clone this repository and
|
|
reference it in your `~/.zshrc`:
|
|
|
|
$ git clone https://github.com/bhilburn/powerlevel9k.git
|
|
$ echo 'source powerlevel9k/powerlevel9k.zsh-theme' >> ~/.zshrc
|
|
|
|
##### Option 2: Install for Oh-My-ZSH
|
|
|
|
To install this theme for
|
|
[Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh), clone this repository
|
|
into your OMZ `custom/themes` directory.
|
|
|
|
$ cd ~/.oh-my-zsh/custom
|
|
$ git clone https://github.com/bhilburn/powerlevel9k.git themes/powerlevel9k
|
|
|
|
You then need to select this theme in your `~/.zshrc`:
|
|
|
|
ZSH_THEME="powerlevel9k/powerlevel9k"
|
|
|
|
##### Option 3: Install for Prezto
|
|
|
|
To install this theme for use in Prezto, clone this repository into your
|
|
[Prezto](https://github.com/sorin-ionescu/prezto) `prompt/external` directory.
|
|
|
|
$ cd ~.zprezto/modules/prompt/external
|
|
$ git clone https://github.com/bhilburn/powerlevel9k.git
|
|
$ ln -s powerlevel9k/powerlevel9k.zsh-theme ../functions/prompt_powerlevel9k_setup
|
|
|
|
You then need to select this theme in your `~/.zpreztorc`:
|
|
|
|
zstyle ':prezto:module:prompt' theme 'powerlevel9k'
|
|
|
|
##### Option 4: Install for antigen
|
|
|
|
If you prefer [antigen](https://github.com/zsh-users/antigen), just add this
|
|
theme to the antigen config in your `~/.zshrc`:
|
|
|
|
$ echo 'antigen theme bhilburn/powerlevel9k powerlevel9k' >> ~/.zshrc
|
|
$ echo 'antigen apply' >> ~/.zshrc
|
|
|
|
Note that you should define any customizations before calling `antigen theme`
|
|
(i.e. setting the `POWERLEVEL9K_*` variables) in your `.zshrc`.
|
|
|
|
#### Step 2: Install Powerline Fonts
|
|
Technically, you don't *have* to install Powerline fonts. If you are using
|
|
a font that has some of the basic glyphs we need, you can use the theme in
|
|
`compatible` mode - see the third option, below.
|
|
|
|
To get the most out of theme, though, you'll want Powerline-patched fonts. There
|
|
are two varieties of these: 'Powerline Fonts' and 'Awesome Powerline
|
|
Fonts'. The latter includes additional glyphs that aren't required for a normal
|
|
install.
|
|
|
|
Do one of the following:
|
|
|
|
##### Option 1: Install Powerline Fonts
|
|
|
|
You can find the [installation instructions for Powerline Fonts here]
|
|
(https://powerline.readthedocs.org/en/latest/installation/linux.html#fonts-installation).
|
|
You can also find the raw font files [in this Github
|
|
repository](https://github.com/powerline/fonts) if you want to manually install
|
|
them for your OS.
|
|
|
|
After you have installed Powerline fonts, make the default font in your terminal
|
|
emulator the Powerline font you want to use.
|
|
|
|
This is the default mode for `Powerlevel9k`, and no further configuration is
|
|
necessary.
|
|
|
|
**N.B.:** If Powerlevel9k is not working properly, it is almost always the case
|
|
that the fonts were not properly installed, or you have not configured your
|
|
terminal to use a Powerline-patched font!
|
|
|
|
##### Option 2: Install Awesome Powerline Fonts
|
|
|
|
Alternatively, you can install [Awesome Powerline
|
|
Fonts](https://github.com/gabrielelana/awesome-terminal-fonts), which provide
|
|
a number of additional glyphs.
|
|
|
|
You then need to indicate that you wish to use the additional glyphs by defining
|
|
the following in your `~/.zshrc`:
|
|
|
|
POWERLEVEL9K_MODE='awesome-patched'
|
|
|
|
If you choose to make use of this, your prompt will look something like this:
|
|
|
|
|
|
|
|
Note that if you prefer flat segment transitions, you can use the following with
|
|
`Awesome Powerline Fonts` installed:
|
|
|
|
POWERLEVEL9K_MODE='flat'
|
|
|
|
Which looks like this:
|
|
|
|
|
|
|
|
##### Option 3: Compatible Mode
|
|
|
|
This option is best if you prefer not to install additional fonts. This option
|
|
will work out-of-the-box if your your terminal font supports the segment
|
|
separator characters `\uE0B0` (left segment separator) and `\uE0B2` (right
|
|
segment separator).
|
|
|
|
All you need to do to in this case is install the `Powerlevel9k` theme itself,
|
|
as explained above, and then define the following in your `~/.zshrc`:
|
|
|
|
POWERLEVEL9K_MODE='compatible'
|
|
|
|
Note that depending on your terminal font, this may still not render
|
|
appropriately. This configuration should be used as a back-up.
|
|
|
|
### Segment Customization
|
|
|
|
Customizing your prompt is easy! Select the segments you want to have displayed,
|
|
and then assign them to either the left or right prompt. The segments that are
|
|
currently available are:
|
|
|
|
* **aws** - The current AWS profile, if active (more info below)
|
|
* **context** - Your username and host (more info below)
|
|
* **dir** - Your current working directory.
|
|
* **history** - The command number for the current line.
|
|
* **node_version** - Show the version number of the installed Node.js.
|
|
* **rbenv** - Ruby environment information (if one is active).
|
|
* **rspec_stats** - Show a ratio of test classes vs code classes for RSpec.
|
|
* **status** - The return code of the previous command, and status of background jobs.
|
|
* **symfony2_tests** - Show a ratio of test classes vs code classes for Symfony2.
|
|
* **symfony2_version** - Show the current Symfony2 version, if you are in a Symfony2-Project dir.
|
|
* **time** - System time.
|
|
* **virtualenv** - Your Python [VirtualEnv](https://virtualenv.pypa.io/en/latest/).
|
|
* **vcs** - Information about this `git` or `hg` repository (if you are in one).
|
|
|
|
To specify which segments you want, just add the following variables to your
|
|
`~/.zshrc`. If you don't customize this, the below configuration is the default:
|
|
|
|
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
|
|
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status history time)
|
|
|
|
#### The AWS Profile Segment
|
|
|
|
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>
|
|
|
|
#### The 'context' Segment
|
|
|
|
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
|
|
when it's likely you need it).
|
|
|
|
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>
|
|
|
|
#### The 'dir' segment
|
|
|
|
The `dir` segment shows the current working directory. You can limit the output
|
|
to a certain length:
|
|
|
|
# Limit to the last two folders
|
|
POWERLEVEL9K_SHORTEN_DIR_LENGTH=2
|
|
|
|
#### The 'time' segment
|
|
|
|
By default the time is show in 'H:M:S' format. If you want to change it,
|
|
just set another format in your `~/.zshrc`:
|
|
|
|
# Reversed time format
|
|
POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}'
|
|
|
|
#### Unit Test Ratios
|
|
|
|
The `symfony2_tests` and `rspec_tests` 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.
|
|
|
|
#### The 'vcs' Segment
|
|
|
|
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
|
|
`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,
|
|
set `POWERLEVEL9K_CHANGESET_HASH_LENGTH` to any value you want.
|
|
|
|
# enable the vcs segment in general
|
|
POWERLEVEL9K_SHOW_CHANGESET=true
|
|
# just show the 6 first characters of changeset
|
|
POWERLEVEL9K_CHANGESET_HASH_LENGTH=6
|
|
|
|
You can also disable the branch icon in your prompt by setting
|
|
`POWERLEVEL9K_HIDE_BRANCH_ICON` to `true`:
|
|
|
|
# Hide the branch icon
|
|
POWERLEVEL9K_HIDE_BRANCH_ICON=true
|
|
|
|
##### 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
|
|
|--------------|---------------------|-------------------|--------------------------
|
|
| `↑4` | `↑4` | 4 | Number of commits your repository is ahead of your remote branch
|
|
| `↓5` | `↓5` | 5 | Number of commits your repository is behind of your remote branch
|
|
| `⍟3` | `⍟3` | 3 | Number of stashes, here 3.
|
|
| `●` | `●` |  | There are unstaged changes in your working copy
|
|
| `✚` | `✚` |  | There are staged changes in your working copy
|
|
| `?` | `?` |  | There are files in your working copy, that are unknown to your repository
|
|
| `→` | `→` |  | The name of your branch differs from its tracking branch.
|
|
| `☿` | `☿` |  | A mercurial bookmark is active.
|
|
| `@` |  |  | Branch Icon
|
|
| None | None | 2c3705 | The current commit hash. Here "2c3705"
|
|
| None | None |  | Repository is a git repository
|
|
| None | None |  | Repository is a Mercurial repository
|
|
|
|
### Styling
|
|
|
|
You can configure the look and feel of your prompt easily with some built-in
|
|
options.
|
|
|
|
#### Double-Lined Prompt
|
|
|
|
By default, `powerlevel9k` is a single-lined prompt. If you would like to have
|
|
the segments display on one line, and print the command prompt below it, simply
|
|
define `POWERLEVEL9K_PROMPT_ON_NEWLINE` in your `~/.zshrc`:
|
|
|
|
POWERLEVEL9K_PROMPT_ON_NEWLINE=true
|
|
|
|
Here is what it looks like:
|
|
|
|
|
|
|
|
#### Light Color Theme
|
|
|
|
If you prefer to use "light" colors, simply set `POWERLEVEL9K_COLOR_SCHEME`
|
|
to `light` in your `~/.zshrc`, and you're all set!
|
|
|
|
POWERLEVEL9K_COLOR_SCHEME='light'
|
|
|
|
The 'light' color scheme works well for ['Solarized
|
|
Light'](https://github.com/altercation/solarized) users. Check it out:
|
|
|
|
|
|
|
|
#### Segment Color Customization
|
|
|
|
For each segment in your prompt, you can specify a foreground and background
|
|
color by setting them in your `~/.zshrc`. Use the segment names from the above
|
|
section `Segment Customization`. For example, to change the appearance of the
|
|
`time` segment, you would use:
|
|
|
|
POWERLEVEL9K_TIME_FOREGROUND='red'
|
|
POWERLEVEL9K_TIME_BACKGROUND='blue'
|
|
|
|
Note that you can also use a colorcode value. Example:
|
|
|
|
POWERLEVEL9K_VCS_FOREGROUND='021' # Dark blue
|
|
|
|
For a full list of supported colors, run the `spectrum_ls` program in your
|
|
terminal.
|
|
|
|
#### Special Segment Colors
|
|
|
|
Some segments have additional color options if you want to customize the look of
|
|
your prompt even further. These Segments are `context`, `vcs`, `rspec_stats`,
|
|
`symfony2_tests`:
|
|
|
|
# Customizing `context` colors for root and non-root users
|
|
POWERLEVEL9K_CONTEXT_DEFAULT_BACKGROUND="green"
|
|
POWERLEVEL9K_CONTEXT_DEFAULT_FOREGROUND="cyan"
|
|
POWERLEVEL9K_CONTEXT_ROOT_BACKGROUND="red"
|
|
POWERLEVEL9K_CONTEXT_ROOT_FOREGROUND="blue"
|
|
|
|
# Advanced `vcs` color customization
|
|
POWERLEVEL9K_VCS_FOREGROUND='blue'
|
|
POWERLEVEL9K_VCS_DARK_FOREGROUND='black'
|
|
POWERLEVEL9K_VCS_BACKGROUND='green'
|
|
# If VCS changes are detected:
|
|
POWERLEVEL9K_VCS_MODIFIED_FOREGROUND='red'
|
|
POWERLEVEL9K_VCS_MODIFIED_BACKGROUND='cyan'
|
|
|
|
# rspec_stats for good test coverage
|
|
POWERLEVEL9K_RSPEC_STATS_GOOD_FOREGROUND='blue'
|
|
POWERLEVEL9K_RSPEC_STATS_GOOD_BACKGROUND='green'
|
|
# rspec_stats for average test coverage
|
|
POWERLEVEL9K_RSPEC_STATS_AVG_FOREGROUND='black'
|
|
POWERLEVEL9K_RSPEC_STATS_AVG_BACKGROUND='cyan'
|
|
# rspec_stats for poor test coverage
|
|
POWERLEVEL9K_RSPEC_STATS_BAD_FOREGROUND='red'
|
|
POWERLEVEL9K_RSPEC_STATS_BAD_BACKGROUND='white'
|
|
|
|
# symfony2_tests for good test coverage
|
|
POWERLEVEL9K_SYMFONY2_TESTS_GOOD_FOREGROUND='blue'
|
|
POWERLEVEL9K_SYMFONY2_TESTS_GOOD_BACKGROUND='green'
|
|
# symfony2_tests for average test coverage
|
|
POWERLEVEL9K_SYMFONY2_TESTS_AVG_FOREGROUND='black'
|
|
POWERLEVEL9K_SYMFONY2_TESTS_AVG_BACKGROUND='cyan'
|
|
# symfony2_tests for poor test coverage
|
|
POWERLEVEL9K_SYMFONY2_TESTS_BAD_FOREGROUND='red'
|
|
POWERLEVEL9K_SYMFONY2_TESTS_BAD_BACKGROUND='white'
|
|
|
|
### Troubleshooting
|
|
|
|
Here are some fixes to some common problems.
|
|
|
|
#### Gaps Between Segments
|
|
|
|
You can see this issue in the screenshot, below:
|
|
|
|
|
|
|
|
Thankfully, this is easy to fix. This happens if you have successfully installed
|
|
Powerline fonts, but did not make a Powerline font the default font in your
|
|
terminal emulator (e.g., 'terminator', 'gnome-terminal', 'konsole', etc.,).
|
|
