How to change Alien prompt colors to custom values?

Set environment variables like ALIEN_PROMPT_FG with color codes in .zshrc, or create a custom theme file and specify its path with ALIEN_CUSTOM_THEME_PATH, as shown in the configuration examples.

Alien vs Powerlevel10k for Zsh prompts?

Alien focuses on modular, asynchronous sections with extensive customization, while Powerlevel10k emphasizes speed and pre-configured styles. Choose Alien for deep tailoring, but expect more setup work compared to Powerlevel10k's out-of-the-box experience.

Does Alien work with oh-my-zsh plugin manager?

Yes, Alien supports oh-my-zsh via manual theme overriding, as mentioned in the installation section. Add it to your themes directory and set ZSH_THEME to 'alien' in .zshrc.

How to enable Nerd Font icons in Alien prompt?

Set export ALIEN_USE_NERD_FONT=1 in .zshrc, but ensure Nerd Fonts are installed and configured in your terminal. Note that custom symbol definitions can override this setting.

Can Alien show Python and Node.js versions simultaneously?

Yes, configure ALIEN_VERSIONS_PROMPT with tokens like PYTHON_S and NODE_S to display runtime versions in the prompt, supporting multiple languages as listed in the versions section.

Why is my Alien prompt slow or not updating async?

Ensure sections like vcs_status are marked with :async in ALIEN_SECTIONS_LEFT, and check for font or plugin conflicts. Async rendering depends on zsh-async library, so verify it's loaded correctly.
