what is coralline fr?

Coralline is a status bar for Claude Code, the AI coding assistant that runs in a terminal. It adds a line of information at the bottom of your terminal showing things like your current folder, git branch status, which AI model is active, how much of the context window has been used, session cost in USD, rate-limit gauges, and the current time. The design is inspired by Powerlevel10k, a popular style of terminal prompt used with the Zsh shell. The installation works by pasting a short prompt into Claude Code and letting the AI handle setup. Claude will ask you to pick a color theme from six options, choose which information segments you want displayed, and decide between a single-line or two-line layout. It then writes the configuration files and verifies the result. You can also install it manually by cloning the repository and editing a settings file. The status line refreshes every second. To keep it fast, the script uses a single call to a tool called jq to read all the data at once, and a single git command to get branch name, dirty state, and sync status together. This avoids the slowdown that comes from running many small shell commands in sequence. The script works with the default bash version on macOS and on Linux. You can control which segments appear and in what order through a plain text configuration file. The layout can be fixed across multiple lines or set to auto mode, where it wraps to extra rows when the terminal window gets narrow and fits on one line when there is enough space. Gauges shift from green to yellow to red as they fill, with the color thresholds adjustable. There is also a lean style that drops the colored background shapes in favor of flat colored text, similar to the lean variant of Powerlevel10k. Six themes ship with the project: claude-coral, catppuccin-mocha, nord, gruvbox-dark, tokyo-night, and mono. A theme is a single config file with color assignments, so creating a custom one is straightforward. The project requires jq and a Nerd Font, though a setting disables the font-specific symbols if you do not have one.
