installation

  • Step 0: install rust
$ 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):
# 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:
# 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:
PS1='$(pista)'    # regular variant
PS1='$(pista -m)' # minimal variant
  • Step 2b (zsh): zsh users, add this to your .zshrc:
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.

export VIRTUAL_ENV_DISABLE_PROMPT=1

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