### installation



 - Step 0: install rust

```shell

$ curl https://sh.rustup.rs -sSf | sh

Rust is installed now. Great!



# check if you have the latest version. 

# pista works with rustc >= 1.34

$ rustc --version

rustc 1.36.0 (a53f9df32 2019-07-03)



# update rust if required

$ rustup update

```



 - Step 1a (install from crates.io): install `pista` with `cargo` (rust's package manager):

```shell

# if you want to install from source, skip over to 1b

$ cargo install pista



$ ~/.cargo/bin/pista -V

Pista 0.1.2

# yay!

```

 - Step 1b (install from source): if you *do not* want install from crates.io, you can install from source:

```shell

# install from source

$ git clone https://github.com/nerdypepper/pista --recurse-submodules

$ cargo install --path ./pista --force



$ ~/.cargo/bin/pista -V

Pista 0.1.2

# yay!

```



 - Step 2a (bash): bash users, set your `PS1`:  

```shell

PS1='$(pista)'    # regular variant

PS1='$(pista -m)' # minimal variant

```



 - Step 2b (zsh): zsh users, add this to your `.zshrc`:  

```shell

autoload -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



this is the default configuration. drop this in your `.bashrc` (or `.zshrc`) to get started.

remember to `source ~/.bashrc` (or `source ~/.zshrc`) to observe the changes!



```

# prompt string to display, for regular users

export PROMPT_CHAR="$"

export PROMPT_CHAR_COLOR="green"



# prompt string to display, for the root user

export PROMPT_CHAR_ROOT="#"

export PROMPT_CHAR_ROOT_COLOR="red"



# if SHORTEN_CWD is set to 1, `/home/nerdypepper/code` is shortened to

# `/h/n/code`

export SHORTEN_CWD=1

export CWD_COLOR="white"



# if EXPAND_TILDE is set to 0, `/home/nerdypepper` is shortened to `~`

export EXPAND_TILDE=0



# if HIDE_HOME_CWD is set to 1, path is hidden when in $HOME

export HIDE_HOME_CWD=1



# there are three possible states for a git repo

# - unstaged (working tree has been modified) 

# - staged (staging area has been modified)

# - clean (all staged changes have committed)



# symbol to represent clean repo state

export GIT_CLEAN="·"

export GIT_CLEAN_COLOR="green"



# symbol to represent unstaged repo state

export GIT_WT_MODIFIED="×"

export GIT_WT_MODIFIED_COLOR="red"



# symbol to represent staged repo state

export GIT_INDEX_MODIFIED="±"

export GIT_INDEX_MODIFIED_COLOR="yellow"



# if HEAD ref peels to branch

export BRANCH_COLOR="green"



# if HEAD ref peels to a commit (detached state)

export COMMIT_COLOR="green"
