### installation
```shell
$ cargo install pista
```

cargo is rust's package manager. if you dont have cargo installed, head over to
http://rustup.rs and follow the instructions.  
make sure to add `$HOME/.cargo/bin` to your `$PATH`!


 - bash users, set your `PS1`:  
```shell
PS1="$(pista)"    # regular variant
PS1="$(pista -m)" # minimal variant
```

 - zsh users, add this to your `.zshrc`:  
```shell
autoinit -Uz add-zsh-hook
_pista_prompt() {
	PROMPT=$("pista -z")   # `pista -zm` for the miminal variant
}
add-zsh-hook precmd _pista_prompt
```


`pista` handles prompt modifications when you enter virtual environments.
make sure to disable `virtualenv`'s changes.
```shell
export VIRTUAL_ENV_DISABLE_PROMPT=1
```

thats it! read on if you aren't happy with the defaults.

### configuration
