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.
• 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

PURE_CMD_MAX_EXEC_TIME

The max execution time of a process before its run time is shown when it exits. Defaults to 5 seconds.

PURE_GIT_PULL

Set PURE_GIT_PULL=0 to prevent Pure from checking whether the current Git remote has been updated.

PURE_GIT_UNTRACKED_DIRTY

Set PURE_GIT_UNTRACKED_DIRTY=0 to not include untracked files in dirtiness check. Only really useful on extremely huge repos like the WebKit repo.

PURE_GIT_DELAY_DIRTY_CHECK

Time in seconds to delay git dirty checking for large repositories (git status takes > 5 seconds). The check is performed asynchronously, this is to save CPU. Defaults to 1800 seconds.

PURE_PROMPT_SYMBOL

Defines the prompt symbol. The default value is ❯.

PURE_GIT_DOWN_ARROW

Defines the git down arrow symbol. The default value is ⇣.

PURE_GIT_UP_ARROW

Defines the git up arrow symbol. The default value is ⇡.

Example

# .zshrc

autoload -U promptinit; promptinit

# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10

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.

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

prezto

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

Add prompt pure to your ~/.zpreztorc.

zim

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

Set zprompt_theme='pure' in ~/.zimrc.

antigen

Update your .zshrc file with the following two lines (order matters). Do not use the antigen theme function.

antigen bundle mafredri/zsh-async
antigen bundle sindresorhus/pure

antibody

Update your .zshrc file with the following two lines (order matters):

antibody bundle mafredri/zsh-async
antibody bundle sindresorhus/pure

zplug

Update your .zshrc file with the following two lines:

zplug mafredri/zsh-async, from:github
zplug sindresorhus/pure, use:pure.zsh, from:github, as:theme

FAQ

I am stuck in a shell loop in my terminal that asks me to authenticate. What should I do?

This is a known issue. Using git pull when you get the username prompt should help you to break the loop by giving you a real prompt for this. This has been fixed in git 2.3

I am seeing the error zpty: can't open pseudo terminal: bad file descriptor.

This is a known issue. zsh/zpty requires either legacy bsd ptys or access to /dev/ptmx. Here are some known solutions.

Gentoo

$ sudo sh -c "echo 'SANDBOX_WRITE=\"/dev/ptmx\"' > /etc/sandbox.d/10zsh"
$ sudo emerge -1 zsh

FreeBSD 10.1

On a default setup, running the command kldload pty should do the trick. If you have a custom kernel, you might need to add device pty to the configuration file (example).
