Pure

Pretty, minimal and fast ZSH prompt

Overview

Most prompts are cluttered, ugly and slow. I wanted something visually pleasing that stayed out of my way.

Why?

• Comes with the perfect prompt character. Author went through the whole Unicode range to find it.
• Shows git branch and whether it's dirty (with a *).
• Indicates when you have unpushed/unpulled git commits with up/down arrows. (Check is done asynchronously!)
• Prompt character turns red if the last command didn't exit with 0.
• Command execution time will be displayed if it exceeds the set threshold.
• Username and host only displayed when in an SSH session.
• Shows the current path in the title and the current folder & command when a process is running.
• Support VI-mode indication by reverse prompt symbol (Zsh 5.3+).
• Makes an excellent starting point for your own custom prompt.

Install

Can be installed with npm or manually. Requires Git 2.0.0+ and ZSH 5.2+. Older versions of ZSH are known to work, but they are not recommended.

npm

$ npm install --global pure-prompt

That's it. Skip to Getting started.

Manually

1. Either…

• Clone this repo
• add it as a submodule, or
• just download pure.zsh and async.zsh

2. Symlink pure.zsh to somewhere in $fpath with the name prompt_pure_setup.

3. Symlink async.zsh in $fpath with the name async.

Example

$ ln -s "$PWD/pure.zsh" /usr/local/share/zsh/site-functions/prompt_pure_setup
$ ln -s "$PWD/async.zsh" /usr/local/share/zsh/site-functions/async

Run echo $fpath to see possible locations.

For a user-specific installation (which would not require escalated privileges), simply add a directory to $fpath for that user:

# .zshenv or .zshrc
fpath=("$HOME/.zfunctions" $fpath)

Then install the theme there:

$ ln -s "$PWD/pure.zsh" "$HOME/.zfunctions/prompt_pure_setup"
$ ln -s "$PWD/async.zsh" "$HOME/.zfunctions/async"

Getting started

Initialize the prompt system (if not so already) and choose pure:

# .zshrc
autoload -U promptinit; promptinit
prompt pure

Options

Option	Description	Default value
PURE_CMD_MAX_EXEC_TIME	The max execution time of a process before its run time is shown when it exits.	5 seconds
PURE_GIT_PULL=0	Prevents Pure from checking whether the current Git remote has been updated.
PURE_GIT_UNTRACKED_DIRTY=0	Do not include untracked files in dirtiness check. Mostly useful on large repos (like WebKit).
PURE_GIT_DELAY_DIRTY_CHECK	Time in seconds to delay git dirty checking when git status takes > 5 seconds.	1800 seconds
PURE_PROMPT_SYMBOL	Defines the prompt symbol.	❯
PURE_PROMPT_VICMD_SYMBOL	Defines the prompt symbol used when the vicmd keymap is active (VI-mode).	❮
PURE_GIT_DOWN_ARROW	Defines the git down arrow symbol.	⇣
PURE_GIT_UP_ARROW	Defines the git up arrow symbol.	⇡

Colors

As explained in ZSH's manual, color values can be:

• A decimal integer corresponding to the color index of your terminal. If your $TERM is xterm-256color, see this chart.
• The name of one of the following nine colors: black, red, green, yellow, blue, magenta, cyan, white, and default (the terminal’s default foreground)
• # followed by an RGB triplet in hexadecimal format, for example #424242. Only if your terminal supports 24-bit colors (true color) or when the zsh/nearcolor module is loaded.

Colors can be changed by using zstyle with a pattern of the form :prompt:pure:$color_name and style color. The color names, their default, and what part they affect are:

• execution_time (yellow) - The execution time of the last command when exceeding PURE_CMD_MAX_EXEC_TIME.
• git:arrow (cyan) - For PURE_GIT_UP_ARROW and PURE_GIT_DOWN_ARROW.
• git:branch (242) - The name of the current branch when in a Git repository.
• git:branch:cached (red) - The name of the current branch when the data isn't fresh.
• host (242) - The hostname when on a remote machine.
• path (blue) - The current path, for example, PWD.
• prompt:error (red) - The PURE_PROMPT_SYMBOL when the previous command has failed.
• prompt:success (magenta) - The PURE_PROMPT_SYMBOL when the previous command has succeded.
• user (242) - The username when on remote machine.
• user:root (default) - The username when the user is root.
• virtualenv (242) - The name of the Python virtualenv when in use.

The following diagram shows where each color is applied on the prompt:

path
|          git:branch
|          |       git:arrow
|          |       |        host
|          |       |        |
~/dev/pure master* ⇡ zaphod@heartofgold  42s
venv ❯               |                   |
|    |               |                   execution_time
|    |               user
|    prompt
virtualenv

RGB colors

There are two ways to use RGB colors with the hexadecimal format. The correct way is to use a terminal that support 24-bit colors and enable this feature as explained in the terminal's documentation.

If you can't use such terminal, the module zsh/nearcolor can be useful. It will map any hexadecimal color to the nearest color in the 88 or 256 color palettes of your termial, but without using the first 16 colors, since their values can be modified by the user. Keep in mind that when using this module you won't be able to display true RGB colors. It only allows you to specify colors in a more convenient way. The following is an example on how to use this module:

# .zshrc
zmodload zsh/nearcolor
zstyle :prompt:pure:path color '#FF0000'

Example

# .zshrc

autoload -U promptinit; promptinit

# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10

# change the path color
zstyle :prompt:pure:path color white

# change the color for both `prompt:success` and `prompt:error`
zstyle ':prompt:pure:prompt:*' color cyan

prompt pure

Tips

In the screenshot you see Pure running in Hyper with the hyper-snazzy theme and Menlo font.

The Tomorrow Night Eighties theme with the Droid Sans Mono font (15pt) is also a nice combination.
Just make sure you have anti-aliasing enabled in your terminal.

To have commands colorized as seen in the screenshot, install zsh-syntax-highlighting.

Integration

oh-my-zsh

1. Set ZSH_THEME="" in your .zshrc to disable oh-my-zsh themes.
2. Follow the Pure Install instructions.
3. Do not enable the following (incompatible) plugins: vi-mode, virtualenv.

NOTE: oh-my-zsh overrides the prompt so Pure must be activated after source $ZSH/oh-my-zsh.sh.

Pure is bundled with Prezto. No need to install it.

Add prompt pure to your ~/.zpreztorc.

zim
