Zsh themes are custom configurations for the Zsh shell, enhancing user experience by altering aesthetics and functionality. They’re part of Oh-My-Zsh, a community-driven framework managing Zsh configuration.
Creating a custom theme involves creating a new file in the ‘themes’ directory under Oh-My-Zsh’s installation path. The filename should be your desired theme name with ‘.zsh-theme’ extension.
Inside this file, you define how your prompt looks using variables like $PS1 (primary prompt string) and $RPS1 (right-hand side prompt). You can also customize colors using ANSI color codes or Zsh’s ‘%F{color}’ syntax. For example, ‘%F{red}Hello World%f’ would print ‘Hello World’ in red.
You can add Git status information to your prompt using vcs_info, a built-in function that provides version control system info. To use it, enable it in .zshrc file (‘zstyle ‘:vcs_info:*’ enable git’) and call it in your theme file (‘$(vcs_info_msg_0_)’).
After saving your theme file, set it as your current theme by changing the value of ZSH_THEME variable in .zshrc file to your theme name.
