安装

• 步骤 0：安装 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

• 步骤 1a（从crates.io安装）：使用 cargo（Rust的包管理器）安装 pista

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

$ ~/.cargo/bin/pista -V
Pista 0.1.2
# yay!

• 步骤 1b（从源代码安装）：如果您不想从crates.io安装，可以从源代码安装

# 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!

• 步骤 2a（bash）：bash用户，设置您的 PS1

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

• 步骤 2b（zsh）：zsh用户，将其添加到您的 .zshrc

autoload -Uz add-zsh-hook
_pista_prompt() {
	PROMPT="$(pista -z)"   # `pista -zm` for the miminal variant
}
add-zsh-hook precmd _pista_prompt

pista 处理虚拟环境中的提示符修改。请确保禁用 virtualenv 的更改。

export VIRTUAL_ENV_DISABLE_PROMPT=1

就这样！如果您对默认设置不满意，请继续阅读。

配置

这是默认配置。将其放入您的 .bashrc（或 .zshrc）以开始。请记住，为了观察更改，请执行 source ~/.bashrc（或 source ~/.zshrc）！

# 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

# 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"
