wj-prompt 1.0.0b1

Installs a WaterJuice shell prompt into your bash or zsh run-command file

wj-prompt

A WaterJuice project.

A small CLI that installs a WaterJuice shell prompt into your bash or zsh run-command file. The prompt shows the host name and working directory in cyan, followed by a green $ for normal users (or a red # for root):

myhost:~/code/wj-prompt $

The prompt line is written inside a clearly marked block, so re-running updates it in place and uninstall removes it cleanly without disturbing the rest of your rc file.

Usage

# Install (or update) the prompt for your current shell
uvx wj-prompt

# Preview the change without writing anything
uvx wj-prompt --dry-run

# Target a specific shell or rc file
uvx wj-prompt --shell bash
uvx wj-prompt --rc-file ~/.bashrc

# Remove the prompt again
uvx wj-prompt uninstall

After installing, restart your shell or source the rc file to apply the change to the current session.

What gets installed

zsh (~/.zshrc):

PROMPT='%F{cyan}%m%f:%F{cyan}%~%f %(!.%F{red}#%f.%F{green}$%f) '

bash (~/.bashrc):

PS1='\[\e[36m\]\h\[\e[0m\]:\[\e[36m\]\w\[\e[0m\] \[\e[$((EUID?32:31))m\]\$\[\e[0m\] '

Each is wrapped in a managed block:

# >>> wj-prompt >>>
# Managed by wj-prompt. Re-run `wj-prompt` to update; `wj-prompt uninstall` to remove.
...
# <<< wj-prompt <<<
