Pretty, minimal and fast ZSH prompt (based on pure)
npm install impure-prompt> Pretty, minimal and fast ZSH prompt

Most prompts are cluttered, ugly and slow. I wanted something visually pleasing that stayed out of my way.
- 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.
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.
``console`
$ npm install --global impure-prompt
That's it. Skip to Getting started.
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
`console`
$ 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/asyncecho $fpath
Run to see possible locations.
For a user-specific installation (which would not require escalated privileges), simply add a directory to $fpath for that user:
`sh`.zshenv or .zshrc
fpath=( "$HOME/.zfunctions" $fpath )
Then install the theme there:
`console`
$ ln -s "$PWD/impure.zsh" "$HOME/.zfunctions/prompt_impure_setup"
$ ln -s "$PWD/async.zsh" "$HOME/.zfunctions/async"
Initialize the prompt system (if not so already) and choose impure:
`sh`.zshrc
autoload -U promptinit; promptinit
prompt impure
The max execution time of a process before its run time is shown when it exits. Defaults to 5 seconds.
Set IMPURE_GIT_PULL=0 to prevent impure from checking whether the current Git remote has been updated.
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.
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.
Defines the prompt symbol. The default value is ❯.
Defines the git branch symbol. The default value is . (probably not visible correctly if the font in use doesn't support this unicode char )
Defines the git down arrow symbol. The default value is ⇣.
Defines the git up arrow symbol. The default value is ⇡.
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.
1. Symlink (or copy) impure.zsh to ~/.oh-my-zsh/custom/impure.zsh-theme.async.zsh
2. Symlink (or copy) to ~/.oh-my-zsh/custom/async.zsh.ZSH_THEME="impure"
3. Set 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.
