You have several options to accept or reject these changes: - -### Accepting Changes - -- **`:w` (save)** - Accept the changes and apply them to your file -- **`aa`** - Accept the changes using the dedicated keymap (configured in LazyVim spec) - -You can edit the proposed changes in the right-hand diff buffer before accepting them. This allows you to modify Claude's suggestions or make additional tweaks before applying the final version to your file. - -Both methods signal Claude Code to apply the changes to your file, after which the plugin automatically reloads the affected buffers to show the updated content. +When Claude proposes changes, the plugin opens a native Neovim diff view: -### Rejecting Changes +- **Accept**: `:w` (save) or `aa` +- **Reject**: `:q` or `ad` -- **`:q` or `:close`** - Close the diff view to reject the changes -- **`ad`** - Reject changes using the dedicated keymap (configured in LazyVim spec) -- **`:bdelete` or `:bwipeout`** - Delete the diff buffer to reject changes - -When you reject changes, the diff view closes and the original file remains unchanged. - -### Accepting/Rejecting from Claude Code Terminal - -You can also navigate to the Claude Code terminal window and accept or reject diffs directly from within Claude's interface. This provides an alternative way to manage diffs without using the Neovim-specific keymaps. - -### Customizing Diff Keymaps - -The diff keymaps are configured in the LazyVim spec and can be customized by modifying the `keys` table: - -```lua -{ - "coder/claudecode.nvim", - config = true, - keys = { - -- ... other keymaps ... - - -- Customize diff keymaps to avoid conflicts (e.g., with debugger) - { "ya", "ClaudeCodeDiffAccept", desc = "Accept diff" }, - { "yn", "ClaudeCodeDiffDeny", desc = "Deny diff" }, - - -- Or disable them entirely by omitting them from the keys table - }, -} -``` - -The commands `ClaudeCodeDiffAccept` and `ClaudeCodeDiffDeny` work only in diff buffers created by the plugin and will show a warning if used elsewhere. - -### How It Works - -The plugin uses a signal-based approach where accepting or rejecting a diff sends a message to Claude Code rather than directly modifying files. This ensures consistency and allows Claude Code to handle the actual file operations while the plugin manages the user interface and buffer reloading. - -#### Examples - -```vim -" Add entire files -:ClaudeCodeAdd src/components/Header.tsx -:ClaudeCodeAdd ~/.config/nvim/init.lua - -" Add entire directories (line numbers ignored) -:ClaudeCodeAdd tests/ -:ClaudeCodeAdd ../other-project/ - -" Add specific line ranges -:ClaudeCodeAdd src/main.lua 50 100 " Lines 50 through 100 -:ClaudeCodeAdd config.lua 25 " Only line 25 -:ClaudeCodeAdd utils.py 1 50 " First 50 lines -:ClaudeCodeAdd README.md 10 20 " Just lines 10-20 - -" Path expansion works with line ranges -:ClaudeCodeAdd ~/project/src/app.js 100 200 -:ClaudeCodeAdd ./relative/path.lua 30 -``` +You can edit Claude's suggestions before accepting them. ## How It Works This plugin creates a WebSocket server that Claude Code CLI connects to, implementing the same protocol as the official VS Code extension.

- -### Configuration Options Explained - -#### Server Options - -- **`port_range`**: Port range for the WebSocket server that Claude connects to -- **`auto_start`**: Whether to automatically start the integration when Neovim starts -- **`terminal_cmd`**: Override the default "claude" command (useful for custom Claude installations) -- **`log_level`**: Controls verbosity of plugin logs - -#### Selection Tracking - -- **`track_selection`**: Enables real-time selection updates sent to Claude -- **`visual_demotion_delay_ms`**: Time to wait before switching from visual selection to cursor position tracking - -#### Connection Management - -- **`connection_wait_delay`**: Prevents overwhelming Claude with rapid @ mentions after connection -- **`connection_timeout`**: How long to wait for Claude to connect before giving up -- **`queue_timeout`**: How long to keep queued @ mentions before discarding them - -#### Terminal Configuration - -- **`split_side`**: Which side to open the terminal split (`"left"` or `"right"`) -- **`split_width_percentage`**: Terminal width as a fraction of screen width (0.1 = 10%, 0.5 = 50%) -- **`provider`**: Terminal implementation to use: - - `"auto"`: Try snacks.nvim, fallback to native - - `"snacks"`: Force snacks.nvim (requires folke/snacks.nvim) - - `"native"`: Use built-in Neovim terminal -- **`show_native_term_exit_tip`**: Show help text for exiting native terminal -- **`auto_close`**: Automatically close terminal when commands finish - -#### Diff Options - -- **`auto_close_on_accept`**: Close diff view after accepting changes with `:w` or `aa` -- **`show_diff_stats`**: Display diff statistics (lines added/removed) -- **`vertical_split`**: Use vertical split layout for diffs -- **`open_in_current_tab`**: Open diffs in current tab instead of creating new tabs -

VS Code extension specs (#57) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: implement complete MCP tools compliance with VS Code extension specs Complete implementation of MCP (Model Context Protocol) tool compliance by: - Adding 2 missing tools from VS Code extension - Converting all tool outputs to MCP-compliant format - Exposing internal tools via MCP while preserving existing functionality - Comprehensive test suite updates with robust JSON handling - Updated documentation to reflect 100% VS Code compatibility - **getLatestSelection**: Get most recent text selection (different from getCurrentSelection) - **closeAllDiffTabs**: Close all diff-related tabs/windows with VS Code-compatible output format All tools now return MCP-compliant format: `{content: [{type: "text", text: "JSON-stringified-data"}]}` - **checkDocumentDirty**: Added schema for MCP exposure, success/failure JSON responses - **saveDocument**: Added schema for MCP exposure, detailed success information - **getWorkspaceFolders**: Added schema for MCP exposure, VS Code-compatible structure - **getOpenEditors**: Restructured from `{editors: [...]}` to `{tabs: [...]}` with all VS Code fields - **getCurrentSelection**: Enhanced with proper fallback behavior and MCP format - **openFile**: Added missing parameters (preview, selectToEndOfLine, makeFrontmost, text selection) - **closeTab**: Updated format while keeping internal-only (per Claude Code requirement) - **Text Selection in openFile**: Full implementation of startText/endText pattern matching - **Conditional Output**: openFile returns simple vs detailed responses based on makeFrontmost - **Language Detection**: getOpenEditors includes proper languageId field mapping - **Error Handling**: Comprehensive JSON-RPC error responses throughout - **Robust JSON encoder/decoder**: Custom implementation supporting nested objects and special keys - **Comprehensive test coverage**: All new tools with unit tests - **Updated test expectations**: All existing tests adapted to MCP format - **Format validation**: Tests verify exact VS Code extension compatibility - **CLAUDE.md**: Complete rewrite of MCP tools section with 100% compliance status - **Development Guidelines**: Added MCP tool development patterns and troubleshooting - **Quality Standards**: Updated to reflect 320+ tests with 100% success rate - **Protocol Compliance**: New section documenting VS Code extension feature parity - **Backward compatibility**: No breaking changes to existing API - **VS Code alignment**: Output formats match official VS Code extension exactly - **Internal tools preserved**: close_tab remains internal as required by Claude Code architecture - ✅ 320 tests passing (0 failures, 0 errors) - ✅ All linting checks passing (0 warnings, 0 errors) - ✅ Full MCP protocol compliance - ✅ VS Code extension feature parity achieved Change-Id: Ic1bd33aadb7fa45d64d4aba208acf37b2c9779cb Signed-off-by: Thomas Kosiewski * fix: address PR review comments for MCP tools compliance - Fix closeAllDiffTabs potential duplicate window closing by using set-based approach instead of array - Add comprehensive test coverage for openFile parameters (makeFrontmost, preview mode, line/text selection) - Update CLAUDE.md documentation to mention endLine parameter for openFile tool - Enhance JSON encoder/decoder in test suite with proper escape sequence handling - Add missing vim API mocks for complex openFile functionality testing All 325 tests now pass with complete coverage of new MCP tool features. Change-Id: I15bceb2bb44552205ea63c5ef1cb83722f7b5893 Signed-off-by: Thomas Kosiewski * fix: correct off-by-one indexing error in openFile text pattern search Address Copilot review comment: when searching for endText pattern, line_idx is already the correct 1-based index for the lines array, so accessing lines[line_idx + 1] was incorrect. Changed to lines[line_idx] to access the current line directly.

In Lua 5.4, coroutine.running() returns (thread, is_main) where is_main indicates if running in main thread vs coroutine. Changes: - Update diff.lua: Fix open_diff_blocking coroutine check - Update tools/open_diff.lua: Fix handler coroutine validation - Update tests: Add proper mocking and expected error messages * feat: add mini.files support to claudecode.nvim Add mini.files integration following the same pattern as netrw support. - Add _get_mini_files_selection() function to integrations.lua - Support both visual selection and single file under cursor - Add comprehensive test suite with 12 test cases - Handle error cases and edge conditions gracefully * feat: add multi-file visual selection support to mini.files integration This update introduces support for visual mode multi-file selection in mini.files integration.

The change: - Creates a dedicated `lua/claudecode/types.lua` file containing all public API types - Removes inline type definitions from config.lua, init.lua, and logger.lua - Updates type references across the codebase to use the new centralized types - Improves type naming consistency with the `ClaudeCode` prefix (e.g., `ClaudeCodeConfig` instead of `ClaudeCode.Config`) - Enhances type documentation with more detailed descriptions This change makes the type system more maintainable and provides a single source of truth for the plugin's API types. --- lua/claudecode/config.lua | 33 +------- lua/claudecode/init.lua | 33 +------- lua/claudecode/logger.lua | 4 +- lua/claudecode/terminal.lua | 36 ++------- lua/claudecode/terminal/native.lua | 12 +-- lua/claudecode/terminal/snacks.lua | 6 +- lua/claudecode/types.lua | 117 +++++++++++++++++++++++++++++ 7 files changed, 140 insertions(+), 101 deletions(-) create mode 100644 lua/claudecode/types.lua diff --git a/lua/claudecode/config.lua b/lua/claudecode/config.lua index 5295f0d..d643c80 100644 --- a/lua/claudecode/config.lua +++ b/lua/claudecode/config.lua @@ -6,36 +6,7 @@ local M = {} --- Types (authoritative for configuration shape): ----@class ClaudeCode.DiffOptions ----@field auto_close_on_accept boolean ----@field show_diff_stats boolean ----@field vertical_split boolean ----@field open_in_current_tab boolean ----@field keep_terminal_focus boolean - ----@class ClaudeCode.ModelOption ----@field name string ----@field value string - ----@alias ClaudeCode.LogLevel "trace"|"debug"|"info"|"warn"|"error" - ----@class ClaudeCode.Config ----@field port_range {min: integer, max: integer} ----@field auto_start boolean ----@field terminal_cmd string|nil ----@field env table ----@field log_level ClaudeCode.LogLevel ----@field track_selection boolean ----@field visual_demotion_delay_ms number ----@field connection_wait_delay number ----@field connection_timeout number ----@field queue_timeout number ----@field diff_opts ClaudeCode.DiffOptions ----@field models ClaudeCode.ModelOption[] ----@field disable_broadcast_debouncing?

`keep_empty` (default): Leaves the empty buffer in place - `close_window`: Closes the placeholder split window Previously, when rejecting a new file diff, the plugin would always try to delete the original buffer. This could cause issues when the buffer was reused from an existing empty buffer, leading to potential crashes when attempting to reopen a diff. The PR includes: - New configuration option in `config.lua` with validation - Type definition in `types.lua` - Logic in `diff.lua` to track whether the original buffer was created by the plugin - Only delete the original buffer on reject if it was created by the plugin - Unit test to verify the fix works correctly This change improves stability when working with new files and gives users more control over the UI behavior. --- lua/claudecode/config.lua | 8 ++ lua/claudecode/diff.lua | 21 +++- lua/claudecode/types.lua | 4 + .../unit/new_file_reject_then_reopen_spec.lua | 97

When enabled, the terminal will be focused after sending code to Claude. When disabled (the default), the terminal will only be made visible but not focused. This provides more control over the workflow when interacting with Claude: - Default behavior (false): Terminal becomes visible but doesn't steal focus - Optional behavior (true): Terminal becomes visible and focused after sending The PR includes: - Configuration option in the main config structure - Type definition updates - Implementation in the send_at_mention function - Documentation in

The plugin honors `CLAUDE_CONFIG_DIR` for lock files. +- Local CLI paths (e.g., `opts.terminal_cmd`) should be configured in user config, not hardcoded in repo files. diff --git a/lua/claudecode/config.lua b/lua/claudecode/config.lua index ceed582..b464f8f 100644 --- a/lua/claudecode/config.lua +++ b/lua/claudecode/config.lua @@ -89,7 +89,10 @@ function M.validate(config) assert(is_valid_log_level, "log_level must be one of: " .. table.concat(valid_log_levels, ", ")) assert(type(config.track_selection) == "boolean", "track_selection must be a boolean") - assert(type(config.focus_after_send) == "boolean", "focus_after_send must be a boolean") + -- Allow absence in direct validate() calls; apply() supplies default + if config.focus_after_send ~= nil then + assert(type(config.focus_after_send) == "boolean", "focus_after_send must be a boolean") + end assert( type(config.visual_demotion_delay_ms) == "number" and config.visual_demotion_delay_ms >= 0, @@ -131,7 +134,9 @@ function M.validate(config) if config.diff_opts.on_new_file_reject ~= nil then assert( type(config.diff_opts.on_new_file_reject) == "string" - and (config.diff_opts.on_new_file_reject == "keep_empty" or config.diff_opts.on_new_file_reject == "close_window"), + and ( + config.diff_opts.on_new_file_reject == "keep_empty" or config.diff_opts.on_new_file_reject == "close_window" + ), "diff_opts.on_new_file_reject must be 'keep_empty' or 'close_window'" ) end diff --git a/lua/claudecode/diff.lua b/lua/claudecode/diff.lua index 68ddf9d..2355ecf 100644 --- a/lua/claudecode/diff.lua +++ b/lua/claudecode/diff.lua @@ -814,11 +814,20 @@ function M._resolve_diff_as_rejected(tab_name) diff_data.status = "rejected" diff_data.result_content = result - -- Do not perform UI cleanup here; wait for explicit close_tab tool call. -- Resume the coroutine with the result (for deferred response system) if diff_data.resolution_callback then diff_data.resolution_callback(result) end + + -- For new-file diffs in the current tab, when configured to keep the empty placeholder, + -- we eagerly clean up the diff UI and state.
