impure-prompt v1.1.0

impure

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.
• 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 impure-prompt

That's it. Skip to Getting started.

Manually

1. Either…

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

2. Symlink impure.zsh to somewhere in $fpath with the name prompt_impure_setup.

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

Example

$ ln -s "$PWD/impure.zsh" /usr/local/share/zsh/site-functions/prompt_impure_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 "$PWD/impure.zsh" "$HOME/.zfunctions/prompt_impure_setup"
$ ln -s "$PWD/async.zsh" "$HOME/.zfunctions/async"

Getting started

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

# .zshrc
autoload -U promptinit; promptinit
prompt impure

Options

IMPURE_CMD_MAX_EXEC_TIME

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

IMPURE_GIT_PULL

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

IMPURE_GIT_UNTRACKED_DIRTY

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

IMPURE_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.

IMPURE_PROMPT_SYMBOL

Defines the prompt symbol. The default value is ❯.

IMPURE_GIT_BRANCH_SYMBOL

Defines the git branch symbol. The default value is . (probably not visible correctly if the font in use doesn't support this unicode char <U+E0A0>)

IMPURE_GIT_DOWN_ARROW

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

IMPURE_GIT_UP_ARROW

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

Tips

In the screenshot you see impure running in Hyper with the an-old-hype theme, hyperborder (which gives it that amazing full gradient brackground) and Fira Code font.

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. Symlink (or copy) impure.zsh to ~/.oh-my-zsh/custom/impure.zsh-theme.
2. Symlink (or copy) async.zsh to ~/.oh-my-zsh/custom/async.zsh.
3. Set ZSH_THEME="impure" in your .zshrc file.

Or skip the oh-my-zsh integration above and simply:

1. Set ZSH_THEME="" in your .zshrc to disable oh-my-zsh themes.
2. Follow the impure Install instructions.
