CCometixLine: High-Performance Claude Code Statusline Tool

CCometixLine: A High-Performance Claude Code Statusline Tool in Rust

Overview

CCometixLine is a lean, high-performance statusline utility written in Rust, designed to enhance Claude Code workflows with seamless Git integration, usage tracking, and a robust interactive configuration experience. It blends essential status information—model names, repository state, and contextual data—into a compact, readable statusline, while remaining friendly to developers who value speed, reliability, and customization. The project ships with an interactive TUI (Text User Interface) configuration, multiple theme presets, and a suite of Claude Code enhancement utilities that help users tailor their coding environment without sacrificing performance.

To illustrate its practical use, the project ships with a screenshot highlighting a typical statusline. The image demonstrates how the statusline presents the model in use, the current working directory, Git branch status, and the context window information at a glance. This visual reference underscores the tool’s core promise: a clean, informative, high-contrast display that stays out of the way while you code.

• Theme system: A collection of built-in presets to suit different aesthetics and readability preferences.
• Segment customization: Fine-grained control over what appears in the statusline and how it’s presented.
• Configuration management: Init, check, and edit flows for quick and reliable setup.

Claude Code Enhancement

• Context warning disabler: Eliminate or suppress annoying “Context low” messages that can disrupt focus.
• Verbose mode enabler: Enable more detailed outputs for debugging or in-depth analysis.
• Robust patcher: A resilient patching mechanism that can adapt to Claude Code version updates.
• Automatic backups: Safe edits with straightforward recovery options.
• Safe modification: Changes are designed to be reversible, reducing risk during configuration.

Installation: Quick Start

The recommended path to getting started is a quick install via npm, which works across platforms. After installation, you’ll have a global command ready to integrate with Claude Code.

Quick Install (Recommended)

• Install globally:
• npm: npm install -g @cometix/ccline
• yarn: yarn global add @cometix/ccline
• pnpm: pnpm add -g @cometix/ccline

Faster downloads via a mirror

• npm mirror: npm install -g @cometix/ccline --registry https://registry.npmmirror.com

Post-installation: what you’ll get

• A globally accessible ccline command
• Steps to integrate with Claude Code
• A configuration panel accessible with ccline -c for theme selection

Claude Code Configuration: Integrating with Your Editor

To enable statusline integration in Claude Code, add a small snippet to your settings.json. The cross-platform recommended configuration is straightforward and works on all major environments.

Cross-Platform (Recommended)

{ "statusLine": { "type": "command", "command": "~/.claude/ccline/ccline", "padding": 0 } }

Note for Windows users

• Starting from Claude Code v2.1.47+, Unix-style path parsing is supported. The tilde (~) expands to your home directory automatically, so the path ~./claude/ccline/ccline is reliable. Do not use %USERPROFILE% in the path, as it no longer works reliably in v2.1.47+.
• If you prefer, you can fallback to an npm-based approach with the command "ccline" (requires npm global installation).

Fallback (npm installation)

{ "statusLine": { "type": "command", "command": "ccline", "padding": 0 } }

Update and Maintenance

Keeping CCometixLine up to date is straightforward. The recommended command to refresh your installation is:

npm update -g @cometix/ccline

Manual Installation: Expanded Options

For those who prefer not to rely on a package manager, or who require offline deployment, there are Linux, macOS, and Windows installation options. The following paths are designed to be robust across environments and distributions.

Linux: Dynamic or Static Binary Option 1 (Dynamic Binary, recommended)

• Create configuration directory and download:
• mkdir -p ~/.claude/ccline
• wget https://github.com/Haleclipse/CCometixLine/releases/latest/download/ccline-linux-x64.tar.gz
• tar -xzf ccline-linux-x64.tar.gz
• cp ccline ~/.claude/ccline/
• chmod +x ~/.claude/ccline/ccline

Option 2 (Static Binary, universal)

• Similar steps with ccline-linux-x64-static.tar.gz

macOS: Intel and Apple Silicon

• Intel: Download and unpack, then copy to ~/.claude/ccline and set executable permissions
• Apple Silicon: Same steps, ensuring the correct arm64 binary is used

Windows

• A PowerShell-based approach creates the destination directory under your user profile and downloads a Windows-specific zip, then expands and places the executable into the appropriate folder.

Build from Source

If you prefer to build locally from source: git clone https://github.com/Haleclipse/CCometixLine.git cd CCometixLine cargo build --release

Post-build steps

• Copy the released binary to ~/.claude/ccline and mark it executable
• Windows users can copy the produced binaries into the corresponding user profile subdirectory

Usage: Day-to-day Operations

The tool’s usage is designed to be intuitive, with theme overrides and Claude Code enhancements available through command-line switches.

Theme Override

• Temporarily switch themes for specific tasks or demonstrations:
• ccline --theme cometix
• ccline --theme minimal
• ccline --theme gruvbox
• ccline --theme nord
• ccline --theme powerline-dark
• You can also point to theme files from ~/.claude/ccline/themes/ for custom configurations:
• ccline --theme my-custom-theme

Claude Code Enhancement: Patch and Context Handling

• Disable context warnings and enable verbose mode:
• ccline --patch /path/to/claude-code/cli.js
• Example: ccline --patch ~/.local/share/fnm/node-versions/v24.4.1/installation/lib/node_modules/@anthropic-ai/claude-code/cli.js

Default Segments and Their Meaning

The statusline is composed of several segments. By default, you’ll see:

• Directory
• Git Branch Status
• Model
• Context Window

Git Status Indicators

• Branch name is displayed with a Nerd Font icon
• Status symbols:
• ✓ Clean
• ● Dirty
• ⚠ Conflicts
• Remote tracking indicators:
• ↑n Ahead
• ↓n Behind

Model Display

• The statusline shows simplified Claude model names. For example:
• claude-3-5-sonnet → Sonnet 3.5
• claude-4-sonnet → Sonnet 4

Context Window Display

• Provides token usage estimates with context limit tracking, helping you gauge how much of the transcript is currently in context.

Configuration and Customization

CCometixLine supports full TOML-based configuration alongside a powerful interactive editor. Several elements are configurable, from the basic enable/disable toggles to the granularity of separators and icons.

Configuration File and Interactive Editing

• Configuration file: ~/.claude/ccline/config.toml
• Interactive TUI: ccline --config for real-time editing with live preview
• Theme files: ~/.claude/ccline/themes/*.toml for custom themes
• Automatic initialization: ccline --init creates a default configuration

Available Segments

All segments are configurable to suit your needs:

• Enable/disable toggles
• Custom separators and icons
• Color customization
• Format options

Model Configuration (models.toml)

Location: ~/.claude/ccline/models.toml (auto-created on first run) This file defines how model IDs appear in the statusline and their context window limits. Claude models (Sonnet, Opus, Haiku) are automatically recognized with version extraction. You only need this file if you want overrides or to add third-party models.

Example: basic model entries and context modifiers

# Model entries: simple substring matching on the model ID
[[models]]
pattern = "glm-4.5"
display_name = "GLM-4.5"
context_limit = 128000

[[models]]
pattern = "kimi-k2"
display_name = "Kimi K2"
context_limit = 128000

# Context modifiers: matched independently and composable with model entries
# Overrides context_limit and appends display_suffix to the display name
# e.g., model "Opus 4" + modifier " 1M" = "Opus 4 1M"
[[context_modifiers]]
pattern = "\[1m\]"
display_suffix = " 1M"
context_limit = 1000000

Requirements: What You Need to Run It Well

• Git: Version 1.5+ (Git 2.22+ recommended for better branch detection)
• Terminal: Must support Nerd Fonts for proper icon display
• Install a Nerd Font (examples include FiraCode Nerd Font, JetBrains Mono Nerd Font)
• Configure your terminal to use the Nerd Font
• Claude Code: Required for statusline integration
