CodeContinue - AI Code Completion for Sublime Text

An LLM-powered Sublime Text plugin that provides intelligent inline code completion suggestions, in-place code editing, and code chat using OpenAI-compatible or Anthropic APIs. Check out the CodeContinue blog post here.

Features

• Fast inline code completion: Powered by your choice of local or cloud LLM.
• Inline Edit & Refactor: Select code >> right-click >> CodeContinue: Edit Selection to rewrite code using natural language instructions.
• Chat about code: Select code >> right-click >> CodeContinue: Chat about Selection to discuss code in an interactive split-view chat.
• Automatic Endpoint & Model Discovery: Paste your server address (e.g. http://localhost:1234 or https://api.openai.com); CodeContinue automatically normalizes the URL and detects available models from /v1/models.
• Flexible Keyboard Shortcuts: Enter to suggest, Tab to accept (⚠️ Note: Keybindings are customizable and enabled via settings).
• Multi-Provider Support: Works out-of-the-box with OpenAI, Anthropic, LM Studio, Ollama, vLLM, and local OpenAI-compatible servers.
• Context-aware: Uses surrounding code context to produce accurate suggestions.

Installation

Option 1: Install via Package Control (Recommended)

1. Open the command palette via Ctrl + Shift + P (or Cmd + Shift + P on macOS).
2. Type Package Control: Install Package and press Enter.
3. Search for CodeContinue and press Enter to install.
4. Configure CodeContinue:
   • The setup wizard appears automatically on first run (or run Ctrl+Shift+P >> CodeContinue: Configure).
   • Enter your endpoint URL (e.g. http://localhost:1234 for LM Studio or https://api.openai.com).
   • Select your model from the auto-detected list or enter it manually.

Enable Key Bindings

Keybindings are not enabled by default to prevent conflicts with existing packages.

To enable keybindings: 1. Open the command palette (Ctrl + Shift + P). 2. Type Preferences: CodeContinue Key Bindings and press Enter. 3. Add your preferred keybinding to the User keymap (e.g. Tab, Right Arrow, or Ctrl+Enter):

[
    { "keys": ["tab"], "command": "code_continue_accept" }
]

Option 2: Manual Install (For Developers)

1. Python CLI Installer

python tools/install.py

Interactive command-line installer with auto-detection, connectivity pre-flight check, and dynamic model discovery.

1. GUI Installer

python tools/install_gui.py

Cross-platform Tkinter graphical installer with automatic model detection and customizable configuration.

Configuration

Settings are saved automatically in Packages/User/CodeContinue.sublime-settings. Reconfigure anytime via Ctrl+Shift+P >> CodeContinue: Configure.

• endpoint: Your API endpoint URL - Required

  • LM Studio: http://localhost:1234
  • Ollama: http://localhost:11434
  • OpenAI: https://api.openai.com (or https://api.openai.com/v1/chat/completions)
  • Anthropic: https://api.anthropic.com (or https://api.anthropic.com/v1/messages)

• model: The model name for completions - Required

  • Examples: qwen2.5-coder-3b-instruct, gpt-4o, claude-3-5-sonnet-20241022

• api_key: Authentication key (optional)

  • Required for cloud providers (e.g. sk-... for OpenAI, sk-ant-... for Anthropic).
  • Leave blank for local endpoints that do not require auth.

• max_context_lines: Number of surrounding code lines sent to the model (default: 30).

• timeout_ms: Request timeout in milliseconds (default: 30000).

• trigger_language: Array of language scopes to enable completion for (e.g. ["python", "cpp", "javascript", "typescript", "go", "rust"]).

• system_prompt: Custom system prompt for inline completions.

  • Leave blank ("") to use the built-in default expert prompt.
  • Set a custom prompt to tune smaller models or suppress docstrings/comments.

• debug: Enable debug logging (default: false).

  • Set to true to view detailed request/response logs in View >> Show Console.

Requirements

• Sublime Text 4
• Python 3.8+ (bundled with Sublime Text 4)
• Access to a local LLM runner (LM Studio, Ollama, vLLM) or a cloud API (OpenAI, Anthropic, etc.)

Troubleshooting

Setup wizard not appearing

• Restart Sublime Text: File >> Exit, then reopen.
• Manually run: Preferences >> Package Settings >> CodeContinue >> Settings or Ctrl+Shift+P >> CodeContinue: Configure.

Suggestions not appearing

• Check that the current file's syntax matches an entry in trigger_language.
• Verify your API endpoint is accessible.
• Enable debug logging ("debug": true) and check View >> Show Console.
• Make sure keybindings are configured in Preferences: CodeContinue Key Bindings.

Timeout errors

• Increase timeout_ms in settings (e.g. 45000 for larger local models).
• Check that your local LLM server is running and responding.

Authentication or connection errors

• Verify your API key is correct.
• For local servers (LM Studio / Ollama), ensure the local server is started and listening on the configured port.
