Planned Features for IDE Integration Parity

+ +

To match the full feature set of GUI IDE integrations (VSCode, JetBrains, etc.), the following features are planned:

+ +
    +
  • File Reference Shortcut: Keyboard mapping to insert @File#L1-99 style references into Claude prompts.
    • +
  • **External /ide Command Support:** Ability to attach an external Claude Code CLI session to a running Neovim MCP server, similar to the /ide command in GUI IDEs.
    • +
  • User-Friendly Config UI: A terminal-based UI for configuring plugin options, making setup more accessible for all users.
    • +
+ +

These features are tracked in the ROADMAP.md and will ensure full parity with Anthropic's official IDE integrations.

+ +

+

Requirements

+ +
    +
  • Neovim 0.7.0 or later
    • +
  • Claude Code CLI installed
    • +
  • The plugin automatically detects Claude Code in the following order: + +
    +1. Custom path specified in config.cli_path (if provided)
+2. Local installation at ~/.claude/local/claude (preferred)
+3. Falls back to claude in PATH
+
    +
    • +
  • plenary.nvim (dependency for git operations)
    • +
+ +

See CHANGELOG.md for version history and updates.

+ +

+

+ +

Using lazy.nvim

+ + +
+return {
+  "greggh/claude-code.nvim",
+  dependencies = {
+    "nvim-lua/plenary.nvim", -- Required for git operations
+  },
+  config = function()
+    require("claude-code").setup()
+  end
+}
+
+ + +

Using packer.nvim

+ + +
+use {
+  'greggh/claude-code.nvim',
+  requires = {
+    'nvim-lua/plenary.nvim', -- Required for git operations
+  },
+  config = function()
+    require('claude-code').setup()
+  end
+}
+
+ + +

Using vim-plug

+ + +
+Plug 'nvim-lua/plenary.nvim'
+Plug 'greggh/claude-code.nvim'
+" After installing, add this to your init.vim:
+" lua require('claude-code').setup()
+
+ + +

+

MCP Server

+ +

The plugin includes a pure Lua implementation of an MCP (Model Context Protocol) server that allows Claude Code to directly interact with your Neovim instance.

+ +

Quick Start

+ +
    +
  1. Add to Claude Code MCP configuration:
    2. +
+ +

```bash + # Add the MCP server to Claude Code + claude mcp add neovim-server /path/to/claude-code.nvim/bin/claude-code-mcp-server + ```

+ +
    +
  1. Start Neovim and the plugin will automatically set up the MCP server:
    2. +
+ +

```lua + require('claude-code').setup({

+ +
+mcp = {
+  enabled = true,
+  auto_start = false  -- Set to true to auto-start with Neovim
+}
+
+ +

}) + ```

+ +
    +
  1. Use Claude Code with full Neovim integration:
    2. +
+ +

```bash + claude "refactor this function to use async/await" + # Claude can now see your current buffer, edit it directly, and run Vim commands + ```

  • <leader>cC - Toggle Claude Code with --continue flag
    • +
  • <leader>cV - Toggle Claude Code with --verbose flag
    • +
+ +

Additionally, when in the Claude Code terminal:

+ +
    +
  • <C-h> - Move to the window on the left
    • +
  • <C-j> - Move to the window below
    • +
  • <C-k> - Move to the window above
    • +
  • <C-l> - Move to the window on the right
    • +
  • <C-f> - Scroll full-page down
    • +
  • <C-b> - Scroll full-page up
    • +
+ +

Note: After scrolling with <C-f> or <C-b>, you'll need to press the i key to re-enter insert mode so you can continue typing to Claude Code.

+ +

When Claude Code modifies files that are open in Neovim, they'll be automatically reloaded.

+ +

+

How it Works

+ +

This plugin provides two complementary ways to interact with Claude Code:

+ +

Terminal Interface

+ +
    +
  1. Creates a terminal buffer running the Claude Code CLI
    2. +
  2. Sets up autocommands to detect file changes on disk
    3. +
  3. Automatically reloads files when they're modified by Claude Code
    4. +
  4. Provides convenient keymaps and commands for toggling the terminal
    5. +
  5. Automatically detects git repositories and sets working directory to the git root
    6. +
+ +

Context-Aware Integration

+ +
    +
  1. Analyzes your codebase to discover related files through imports/requires
    2. +
  2. Tracks recently accessed files within your project
    3. +
  3. Provides multiple context modes (file, selection, workspace)
    4. +
  4. Automatically passes relevant context to Claude Code CLI
    5. +
  5. Supports multiple programming languages (Lua, JavaScript, TypeScript, Python, Go)
    6. +
+ +

MCP Server

+ +
    +
  1. Runs a pure Lua MCP server exposing Neovim functionality
    2. +
  2. Provides tools for Claude Code to directly edit buffers and run commands
    3. +
  3. Exposes enhanced resources including related files and workspace context
    4. +
  4. Enables programmatic access to your development environment
    5. +

File Reference Shortcut ✨

+ +
    +
  • Quickly insert a file reference in the form @File#L1-99 into the Claude prompt input.
    • +
  • How to use:
    • +
  • Press <leader>cf in normal mode to insert the current file and line (e.g., @myfile.lua#L10).
    • +
  • In visual mode, <leader>cf inserts the current file and selected line range (e.g., @myfile.lua#L5-7).
    • +
  • Where it works:
    • +
  • Inserts into the Claude prompt input buffer (or falls back to the command line if not available).
    • +
  • Why:
    • +
  • Useful for referencing code locations in your Claude conversations, just like in VSCode/JetBrains integrations.
    • +
+ +

Examples:

+ +
    +
  • Normal mode, cursor on line 10: @myfile.lua#L10
    • +
  • Visual mode, lines 5-7 selected: @myfile.lua#L5-7

According to the official specification¹, MCP uses JSON-RPC 2.0 over WebSocket or HTTP transport layers. + +### Core protocol components + +#### 1. transport layer + +MCP supports two transport mechanisms²: + +- **WebSocket**: For persistent, bidirectional communication +- **HTTP/HTTP2**: For request-response patterns + +For our MCP server, stdio is the standard transport (following MCP conventions): + +```lua +-- Example server configuration +{ + transport = "stdio", -- Standard for MCP servers + name = "claude-code-nvim", + version = "1.0.0", + capabilities = { + tools = true, + resources = true, + prompts = false + } +} + +```text + +#### 2. message format + +All MCP messages follow JSON-RPC 2.0 specification³: + +- Request messages include `method`, `params`, and unique `id` +- Response messages include `result` or `error` with matching `id` +- Notification messages have no `id` field + +#### 3. authentication + +MCP uses OAuth 2.1 for authentication⁴: + +- Initial handshake with client credentials +- Token refresh mechanism for long-lived sessions +- Capability negotiation during authentication + +### Reference implementations + +Several VSCode extensions demonstrate MCP integration patterns: + +- **juehang/vscode-mcp-server**⁵: Exposes editing primitives via MCP +- **acomagu/vscode-as-mcp-server**⁶: Full VSCode API exposure +-

+```text +STOPPED → STARTING → INITIALIZING → READY → SERVING + ↑ ↓ ↓ ↓ ↓ + └──────────┴────────────┴──────────┴────────┘ + (error/restart) + +```text + +### 2. message router + +Routes messages between Neovim components and MCP server: + +**Components:** + +- **Inbound Queue**: Processes server messages asynchronously +- **Outbound Queue**: Batches and sends client messages +- **Handler Registry**: Maps message types to Lua callbacks +- **Priority System**: Ensures time-sensitive messages (cursor updates) process first + +### 3. session management + +Maintains per-repository Claude instances as specified in CLAUDE.md⁸: + +**Features:** + +- Git repository detection for instance isolation +- Session persistence across Neovim restarts +- Context preservation when switching buffers

commands +- Git status and recent commits + +### 4. semantic context + +Higher-level code understanding: + +**Elements:** + +- Symbol definitions and references (via LSP) +- Call hierarchies and type relationships +- Test coverage information +- Documentation strings and comments + +## Editor operations api + +### 1. text manipulation + +Claude can perform various text operations: + +**Primitive Operations:** + +- `insert(position, text)`: Add text at position +- `delete(range)`: Remove text in range +- `replace(range, text)`: Replace text in range + +**Complex Operations:** + +- Multi-cursor edits with transaction support +- Snippet expansion with placeholders +- Format-preserving transformations + +### 2. diff preview system + +Shows proposed changes before application: + +**Implementation Requirements:** + +- Virtual buffer for diff display +- Syntax highlighting for added/removed lines +- Hunk-level accept/reject controls +- Integration with native diff mode + +### 3. refactoring operations + +Support for project-wide code transformations: + +**Capabilities:** + +- Rename symbol across files (LSP rename) +- Extract function/variable/component +- Move definitions between files +- Safe delete with reference checking + +### 4. file system operations + +Controlled file manipulation: + +**Allowed Operations:** + +- Create files with template support +- Delete files with safety checks +- Rename/move with reference updates +- Directory structure modifications + +**Restrictions:** + +- Require explicit user confirmation +- Sandbox to project directory +- Prevent system file modifications + +## Security & sandboxing + +### 1. permission model + +Fine-grained control over Claude's capabilities: + +**Permission Levels:** + +- **Read-only**: View files and context +- **Suggest**: Propose changes via diff +- **Edit**: Modify current buffer only +- **Full**: All operations with confirmation + +### 2. operation validation + +All Claude operations undergo validation: + +**Checks:** + +- Path traversal prevention +- File size limits for operations +- Rate limiting for expensive operations +- Syntax validation before application + +### 3. audit trail + +Comprehensive logging of all operations: + +**Logged Information:** + +- Timestamp and operation type +- Before/after content hashes +- User confirmation status +- Revert information for undo + +## Technical requirements + +### 1. Lua libraries + +Required dependencies for implementation: + +**Core Libraries:** + +- **lua-cjson**: JSON encoding/decoding⁹ +- **luv**: Async I/O and WebSocket support¹⁰ +- **lpeg**: Parser for protocol messages¹¹ + +**Optional Libraries:** + +- **lua-resty-websocket**: Alternative WebSocket client¹² +- **luaossl**: TLS support for secure connections¹³ + +### 2.

summarizes the comprehensive enhancements made to the claude-code.nvim plugin, focusing on adding context-aware features that mirror Claude Code's built-in IDE integrations while maintaining the powerful MCP (Model Context Protocol) server capabilities. + +## Background + +The original plugin provided: + +- Basic terminal interface to Claude Code command-line tool +- Traditional MCP server for programmatic control +- Simple buffer management and file refresh + +**The Challenge:** Users wanted the same seamless context experience as Claude Code's built-in VS Code/Cursor integrations, where current file, selection, and project context are automatically included in conversations. + +## Implementation summary + +### 1. context analysis module (`lua/claude-code/context.lua`) + +Created a comprehensive context analysis system supporting multiple programming languages: + +#### Language support + +- **Lua**: `require()`, `dofile()`, `loadfile()` patterns +- **JavaScript/TypeScript**: `import`/`require` with relative path resolution +- **Python**: `import`/`from` with module path conversion +- **Go**: `import` statements with relative path handling + +#### Key functions + +- `get_related_files(filepath, max_depth)` - Discovers files through import/require analysis +- `get_recent_files(limit)` - Retrieves recently accessed project files +- `get_workspace_symbols()` - LSP workspace symbol discovery +- `get_enhanced_context()` - Comprehensive context aggregation + +#### Smart features + +- **Dependency depth control** (default: 2 levels) +- **Project-aware filtering** (only includes current project files) +- **Module-to-path conversion** for each language's conventions +- **Relative vs absolute import handling** + +### 2. enhanced terminal interface (`lua/claude-code/terminal.lua`) + +Extended the terminal interface with context-aware toggle functionality: + +#### New function: `toggle_with_context(context_type)` + +**Context Types:** + +- `"file"` - Current file with cursor position (`claude --file "path#line"`) +- `"selection"` - Visual selection as temporary markdown file +- `"workspace"` - Enhanced context with related files, recent files, and current file content +- `"auto"` - Smart detection (selection if in visual mode, otherwise file) + +#### Workspace context features + +- **Context summary file** with current file info, cursor position, file type +- **Related files section** with dependency depth and import counts +- **Recent files list** (top 5 most recent) +- **Complete current file content** in proper markdown code blocks +- **Automatic cleanup** of temporary files after 10 seconds + +### 3. enhanced mcp resources (`lua/claude-code/mcp/resources.lua`) + +Added four new MCP resources for advanced context access: + +#### **`neovim://related-files`** + +```json +{ + "current_file": "lua/claude-code/init.lua", + "related_files": [ + { + "path": "lua/claude-code/config.lua", + "depth": 1, + "language": "lua", + "import_count": 3 + } + ] +} + +```text + +#### **`neovim://recent-files`** + +```json +{ + "project_root": "/path/to/project", + "recent_files": [ + { + "path": "/path/to/file.lua", + "relative_path": "lua/file.lua", + "last_used": 1 + } + ] +} + +```text + +#### **`neovim://workspace-context`** + +Complete enhanced context including current file, related files, recent files, and workspace symbols. + +#### **`neovim://search-results`** + +```json +{ + "search_pattern": "function", + "quickfix_list": [...], + "readable_quickfix": [ + { + "filename": "lua/init.lua", + "lnum": 42, + "text": "function M.setup()", + "type": "I" + } + ] +} + +```text + +### 4. enhanced mcp tools (`lua/claude-code/mcp/tools.lua`) + +Added three new MCP tools for intelligent workspace analysis: + +#### **`analyze_related`** + +- Analyzes files related through imports/requires +- Configurable dependency depth +- Lists imports and dependency relationships +- Returns markdown formatted analysis + +#### **`find_symbols`** + +- LSP workspace symbol search +- Query filtering support +- Returns symbol locations and metadata +- Supports symbol type and container information + +#### **`search_files`** + +- File pattern searching across project +- Optional content inclusion +- Returns file paths with preview content +- Limited results for performance + +### 5. enhanced commands (`lua/claude-code/commands.lua`) + +Added new user commands for context-aware interactions: + +```vim +:ClaudeCodeWithFile " Current file + cursor position +:ClaudeCodeWithSelection " Visual selection +:ClaudeCodeWithContext " Smart auto-detection +:ClaudeCodeWithWorkspace " Enhanced workspace context + +```text + +### 6. test infrastructure consolidation + +Reorganized and enhanced the testing structure: + +#### **directory consolidation:** + +- Moved files from `test/` to organized `tests/` subdirectories +- Created `tests/legacy/` for VimL-based tests +- Created `tests/interactive/` for manual testing utilities +- Updated all references in Makefile, scripts, and CI + +#### **updated references:** + +- Makefile test commands now use `tests/legacy/` +- MCP test script updated for new paths +- CI workflow enhanced with better directory verification +- README updated with new test structure documentation + +### 7. documentation updates + +Comprehensive documentation updates across multiple files: + +#### **readme.md enhancements:** + +- Added context-aware commands section +- Enhanced features list with new capabilities +- Updated MCP server description with new resources +- Added emoji indicators for new features + +#### **roadmap.md updates:** + +- Marked context helper features as completed ✅ +- Added context-aware integration goals +- Updated completion status for workspace context features + +## Technical details + +### **import/require pattern matching** + +The context analysis uses sophisticated regex patterns for each language: + +```lua +-- Lua example +"require%s*%(?['\"]([^'\"]+)['\"]%)?", + +-- JavaScript/TypeScript example +"import%s+.-from%s+['\"]([^'\"]+)['\"]", + +-- Python example +"from%s+([%w%.]+)%s+import", + +```text + +### **path resolution logic** + +Smart path resolution handles different import styles: + +- **Relative imports:** `./module` → `current_dir/module.ext` +- **Absolute imports:** `module.name` → `project_root/module/name.ext` +- **Module conventions:** `module.name` → both `module/name.ext` and `module/name/index.ext` + +### **context file generation** + +Workspace context generates comprehensive markdown files: + +```markdown + +# Workspace context + +**Current File:** lua/claude-code/init.lua +**Cursor Position:** Line 42 +**File Type:** lua + +## Related files (through imports/requires) + +- **lua/claude-code/config.lua** (depth: 1, language: lua, imports: 3) + +## Recent files + +- lua/claude-code/terminal.lua + +## Current file content +
