- Fixed all Rust compilation errors after mass rename

### Phase 3: LiteLLM Integration
- Integrated LiteLLM for multi-provider LLM support (Anthropic, OpenAI, Azure, Google AI, AWS Bedrock, etc.)
- Implemented OpenAI-compatible Chat Completions API support
- Added model family detection and provider-specific handling
- Updated authentication to support LiteLLM API keys
- Renamed environment variables: OPENAI_BASE_URL → LLMX_BASE_URL
- Added LLMX_API_KEY for unified authentication
- Enhanced error handling for Chat Completions API responses
- Implemented fallback mechanisms between Responses API and Chat Completions API

### Phase 4: TypeScript/Node.js Components
- Renamed npm package: @codex/codex-cli → @valknar/llmx
- Updated TypeScript SDK to use new LLMX APIs and endpoints
- Fixed all TypeScript compilation and linting errors
- Updated SDK tests to support both API backends
- Enhanced mock server to handle multiple API formats
- Updated build scripts for cross-platform packaging

### Phase 5: Configuration & Documentation
- Updated all configuration files to use LLMX naming
- Rewrote README and documentation for LLMX branding
- Updated config paths: ~/.codex/ → ~/.llmx/

- Updated all user-facing strings and help text
- Created release plan and migration documentation

### Phase 6: Testing & Validation
- Fixed all Rust tests for new naming scheme
- Updated snapshot tests in TUI (36 frame files)
- Fixed authentication storage tests
- Updated Chat Completions payload and SSE tests
- Fixed SDK tests for new API endpoints
- Ensured compatibility with Claude Sonnet 4.5 model
- Fixed test environment variables (LLMX_API_KEY, LLMX_BASE_URL)

### Phase 7: Build & Release Pipeline
- Updated GitHub Actions workflows for LLMX binary names
- Fixed rust-release.yml to reference llmx-rs/ instead of codex-rs/
- Updated CI/CD pipelines for new package names
- Made Apple code signing optional in release workflow
- Enhanced npm packaging resilience for partial platform builds
- Added Windows sandbox support to workspace
- Updated dotslash configuration for new binary names

### Phase 8: Final Polish
- Renamed all assets (.github images, labels, templates)
- Updated VSCode and DevContainer configurations
- Fixed all clippy warnings and formatting issues
- Applied cargo fmt and prettier formatting across codebase
- Updated issue templates and pull request templates
- Fixed all remaining UI text references

## Technical Details

**Breaking Changes:**
- Binary name changed from `codex` to `llmx`
- Config directory changed from `~/.codex/` to `~/.llmx/`
- Environment variables renamed (CODEX_* → LLMX_*)
- npm package renamed to `@valknar/llmx`

**New Features:**
- Support for 100+ LLM providers via LiteLLM
- Unified authentication with LLMX_API_KEY
- Enhanced model provider detection and handling
- Improved error handling and fallback mechanisms

**Files Changed:**
- 578 files modified across Rust, TypeScript, and documentation
- 30+ Rust crates renamed and updated
- Complete rebrand of UI, CLI, and documentation
- All tests updated and passing

**Dependencies:**
- Updated Cargo.lock with new package names
- Updated npm dependencies in llmx-cli
- Enhanced OpenAPI models for LLMX backend

This release establishes LLMX as a standalone project with comprehensive LiteLLM
integration, maintaining full backward compatibility with existing functionality
while opening support for a wide ecosystem of LLM providers.

# ✅ FIXED: LiteLLM Integration with LLMX
## The Root Cause
The `prompt_cache_key: Extra inputs are not permitted` error was caused by a **hardcoded default provider**.
**File**: `llmx-rs/core/src/config/mod.rs:983`
**Problem**: Default provider was set to `"openai"` which uses the Responses API
**Fix**: Changed default to `"litellm"` which uses the Chat Completions API
## The Error Chain
1. No provider specified → defaults to "openai"
2. OpenAI provider → uses `wire_api: WireApi::Responses`
3. Responses API → sends `prompt_cache_key` field in requests
4. LiteLLM Chat Completions API → rejects `prompt_cache_key` → 400 error
## The Solution
Changed one line in `llmx-rs/core/src/config/mod.rs`:
```rust
// BEFORE:
.unwrap_or_else(|| "openai".to_string());
// AFTER:
.unwrap_or_else(|| "litellm".to_string());
```
## Current Status ✅
- **Binary Built**: `llmx-rs/target/release/llmx` (44MB, built at 16:36)
- **Default Provider**: LiteLLM (uses Chat Completions API)
- **Default Model**: `anthropic/claude-sonnet-4-20250514`
- **Commit**: `e3507a7f`
## How to Use Now
### Option 1: Use Environment Variables (Recommended)
```bash
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
export LITELLM_API_KEY="your-api-key"
# Just run - no config needed!
./llmx-rs/target/release/llmx "hello world"
```
### Option 2: Use Config File
Config at `~/.llmx/config.toml` (already created):
```toml
model_provider = "litellm" # Optional - this is now the default!
model = "anthropic/claude-sonnet-4-20250514"
```
### Option 3: Override via CLI
```bash
./llmx-rs/target/release/llmx -m "openai/gpt-4" "hello"
```
## What This Fixes
✅ No more `prompt_cache_key` errors
✅ Correct API endpoint (`/v1/chat/completions`)
✅ Works with LiteLLM proxy out of the box
✅ No manual provider configuration needed
✅ Config file is now optional (defaults work)
## Commits in This Session
1. **831e6fa6** - Complete comprehensive Llmx → LLMX branding (78 files, 242 changes)
2. **424090f2** - Add LiteLLM setup documentation
3. **e3507a7f** - Fix default provider from 'openai' to 'litellm' ⭐
## Testing
Try this now:
```bash
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
export LITELLM_API_KEY="your-key"
./llmx-rs/target/release/llmx "say hello"
```
Should work without any 400 errors!

# LLMX CLI (Rust Implementation)
We provide LLMX CLI as a standalone, native executable to ensure a zero-dependency install.
## Installing LLMX
Today, the easiest way to install LLMX is via `npm`:
```shell
npm i -g @llmx/llmx
llmx
```
You can also install via Homebrew (`brew install --cask llmx`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/valknar/llmx/releases).
## Documentation quickstart
- First run with LLMX? Follow the walkthrough in [`docs/getting-started.md`](../docs/getting-started.md) for prompts, keyboard shortcuts, and session management.
- Already shipping with LLMX and want deeper control? Jump to [`docs/advanced.md`](../docs/advanced.md) and the configuration reference at [`docs/config.md`](../docs/config.md).
## What's new in the Rust CLI
The Rust implementation is now the maintained LLMX CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
### Config
LLMX supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`docs/config.md`](../docs/config.md) for details.
### Model Context Protocol Support
#### MCP client
LLMX CLI functions as an MCP client that allows the LLMX CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#mcp_servers) for details.
#### MCP server (experimental)
LLMX can be launched as an MCP _server_ by running `llmx mcp-server`. This allows _other_ MCP clients to use LLMX as a tool for another agent.
Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
```shell
npx @modelcontextprotocol/inspector llmx mcp-server
```
Use `llmx mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `llmx mcp-server` to run the MCP server directly.
### Notifications
You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](../docs/config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS.
### `llmx exec` to run LLMX programmatically/non-interactively
To run LLMX non-interactively, run `llmx exec PROMPT` (you can also pass the prompt via `stdin`) and LLMX will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
### Experimenting with the LLMX Sandbox
To test to see what happens when a command is run under the sandbox provided by LLMX, we provide the following subcommands in LLMX CLI:
```
# macOS
llmx sandbox macos [--full-auto] [--log-denials] [COMMAND]...
# Linux
llmx sandbox linux [--full-auto] [COMMAND]...
# Windows
llmx sandbox windows [--full-auto] [COMMAND]...
# Legacy aliases
llmx debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
llmx debug landlock [--full-auto] [COMMAND]...
```
### Selecting a sandbox policy via `--sandbox`
The Rust CLI exposes a dedicated `--sandbox` (`-s`) flag that lets you pick the sandbox policy **without** having to reach for the generic `-c/--config` option:
```shell
# Run LLMX with the default, read-only sandbox
llmx --sandbox read-only
# Allow the agent to write within the current workspace while still blocking network access
llmx --sandbox workspace-write
# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
llmx --sandbox danger-full-access
```
The same setting can be persisted in `~/.llmx/config.toml` via the top-level `sandbox_mode = "MODE"` key, e.g. `sandbox_mode = "workspace-write"`.
## Code Organization
This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:
- [`core/`](./core) contains the business logic for LLMX. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use LLMX.
- [`exec/`](./exec) "headless" CLI for use in automation.
- [`tui/`](./tui) CLI that launches a fullscreen TUI built with [Ratatui](https://ratatui.rs/).
- [`cli/`](./cli) CLI multitool that provides the aforementioned CLIs via subcommands.

# LLMX Release Plan
## Current Status
- Branch: `feature/rebrand-to-llmx`
- 4 commits ready:
1. 831e6fa6 - Comprehensive Llmx → LLMX branding (78 files)
2. 424090f2 - LiteLLM setup documentation
3. e3507a7f - Fix default provider to litellm ⭐
4. a88a2f76 - Summary documentation
- Binary: Built and tested ✅
- LiteLLM integration: Working ✅
## Recommended Strategy
### Step 1: Backup Original Main Branch
```bash
# Create a backup tag/branch of original Llmx code
git checkout main
git tag original-llmx-backup
git push origin original-llmx-backup
# Or create a branch
git branch original-llmx-main
git push origin original-llmx-main
```
### Step 2: Merge to Main
```bash
git checkout main
git merge feature/rebrand-to-llmx
git push origin main
```
### Step 3: Create Release Tag
```bash
git tag -a v0.1.0 -m "Initial LLMX release with LiteLLM integration
- Complete rebrand from Llmx to LLMX
- LiteLLM provider support (Chat Completions API)
- Default model: anthropic/claude-sonnet-4-20250514
- Built-in support for multiple LLM providers via LiteLLM
"
git push origin v0.1.0
```
### Step 4: Build for NPM Release
The project has npm packaging scripts in `llmx-cli/scripts/`:
- `build_npm_package.py` - Builds the npm package
- `install_native_deps.py` - Installs native binaries
```bash
# Build the npm package
cd llmx-cli
python3 scripts/build_npm_package.py
# Test locally
npm pack
# Publish to npm (requires npm login)
npm login
npm publish --access public
```
### Step 5: Update Package Metadata
Before publishing, update:
1. **package.json** version:
```json
{
"name": "@llmx/llmx",
"version": "0.1.0",
"description": "LLMX - AI coding assistant with LiteLLM integration"
}
```
2. **README.md** - Update installation instructions:
```bash
npm install -g @llmx/llmx
```
## Alternative: Separate Repository
If you want to keep original Llmx intact:
1. **Fork to new repo**: `valknar/llmx` (separate from `valknar/llmx`)
2. Push all changes there
3. Publish from the new repo
## NPM Publishing Checklist
- [ ] npm account ready (@valknar or @llmx org)
- [ ] Package name available (`@llmx/llmx` or `llmx`)
- [ ] Version set in package.json (suggest: 0.1.0)
- [ ] Binary built and tested
- [ ] README updated with new name
- [ ] LICENSE file included
- [ ] .npmignore configured
## Versioning Strategy
Suggest semantic versioning:
- **v0.1.0** - Initial LLMX release (current work)
- **v0.2.0** - Additional features
- **v1.0.0** - Stable release after testing
## Post-Release
1. Create GitHub release with changelog
2. Update documentation
3. Announce on relevant channels
4. Monitor for issues
## Files That Need Version Updates
Before release, update version in:
- `llmx-cli/package.json`
- `llmx-cli/Cargo.toml`
- `llmx-rs/cli/Cargo.toml`
- Root `Cargo.toml` workspace

# oai-llmx-ansi-escape
Small helper functions that wrap functionality from
<https://crates.io/crates/ansi-to-tui>:
```rust
pub fn ansi_escape_line(s: &str) -> Line<'static>
pub fn ansi_escape<'a>(s: &'a str) -> Text<'a>
```
Advantages:
- `ansi_to_tui::IntoText` is not in scope for the entire TUI crate
- we `panic!()` and log if `IntoText` returns an `Err` and log it so that
the caller does not have to deal with it

# llmx-app-server
`llmx app-server` is the interface LLMX uses to power rich interfaces such as the [LLMX VS Code extension](https://marketplace.visualstudio.com/items?itemName=openai.chatgpt). The message schema is currently unstable, but those who wish to build experimental UIs on top of LLMX may find it valuable.
## Protocol
Similar to [MCP](https://modelcontextprotocol.io/), `llmx app-server` supports bidirectional communication, streaming JSONL over stdio. The protocol is JSON-RPC 2.0, though the `"jsonrpc":"2.0"` header is omitted.
## Message Schema
Currently, you can dump a TypeScript version of the schema using `llmx app-server generate-ts`, or a JSON Schema bundle via `llmx app-server generate-json-schema`. Each output is specific to the version of LLMX you used to run the command, so the generated artifacts are guaranteed to match that version.
```
llmx app-server generate-ts --out DIR
llmx app-server generate-json-schema --out DIR
```
## Initialization
Clients must send a single `initialize` request before invoking any other method, then acknowledge with an `initialized` notification. The server returns the user agent string it will present to upstream services; subsequent requests issued before initialization receive a `"Not initialized"` error, and repeated `initialize` calls receive an `"Already initialized"` error.
Example:
```json
{ "method": "initialize", "id": 0, "params": {
"clientInfo": { "name": "llmx-vscode", "title": "LLMX VS Code Extension", "version": "0.1.0" }
} }
{ "id": 0, "result": { "userAgent": "llmx-app-server/0.1.0 llmx-vscode/0.1.0" } }
{ "method": "initialized" }
```
## Core primitives
We have 3 top level primitives:
- Thread - a conversation between the LLMX agent and a user. Each thread contains multiple turns.
- Turn - one turn of the conversation, typically starting with a user message and finishing with an agent message. Each turn contains multiple items.
- Item - represents user inputs and agent outputs as part of the turn, persisted and used as the context for future conversations.
## Thread & turn endpoints
The JSON-RPC API exposes dedicated methods for managing LLMX conversations. Threads store long-lived conversation metadata, and turns store the per-message exchange (input → LLMX output, including streamed items). Use the thread APIs to create, list, or archive sessions, then drive the conversation with turn APIs and notifications.
### Quick reference
- `thread/start` — create a new thread; emits `thread/started` and auto-subscribes you to turn/item events for that thread.
- `thread/resume` — reopen an existing thread by id so subsequent `turn/start` calls append to it.
- `thread/list` — page through stored rollouts; supports cursor-based pagination and optional `modelProviders` filtering.
- `thread/archive` — move a threads rollout file into the archived directory; returns `{}` on success.
- `turn/start` — add user input to a thread and begin LLMX generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.
- `turn/interrupt` — request cancellation of an in-flight turn by `(thread_id, turn_id)`; success is an empty `{}` response and the turn finishes with `status: "interrupted"`.
### 1) Start or resume a thread
Start a fresh thread when you need a new LLMX conversation.
```json
{ "method": "thread/start", "id": 10, "params": {
// Optionally set config settings. If not specified, will use the user's
// current config settings.
"model": "gpt-5-llmx",
"cwd": "/Users/me/project",
"approvalPolicy": "never",
"sandbox": "workspaceWrite",
} }
{ "id": 10, "result": {
"thread": {
"id": "thr_123",
"preview": "",
"modelProvider": "openai",
"createdAt": 1730910000
}
} }
{ "method": "thread/started", "params": { "thread": { } } }
```
To continue a stored session, call `thread/resume` with the `thread.id` you previously recorded. The response shape matches `thread/start`, and no additional notifications are emitted:
```json
{ "method": "thread/resume", "id": 11, "params": { "threadId": "thr_123" } }
{ "id": 11, "result": { "thread": { "id": "thr_123", } } }
```
### 2) List threads (pagination & filters)
`thread/list` lets you render a history UI. Pass any combination of:
- `cursor` — opaque string from a prior response; omit for the first page.
- `limit` — server defaults to a reasonable page size if unset.
- `modelProviders` — restrict results to specific providers; unset, null, or an empty array will include all providers.
Example:
```json
{ "method": "thread/list", "id": 20, "params": {
"cursor": null,
"limit": 25,
} }
{ "id": 20, "result": {
"data": [
{ "id": "thr_a", "preview": "Create a TUI", "modelProvider": "openai", "createdAt": 1730831111 },
{ "id": "thr_b", "preview": "Fix tests", "modelProvider": "openai", "createdAt": 1730750000 }
],
"nextCursor": "opaque-token-or-null"
} }
```
When `nextCursor` is `null`, youve reached the final page.
### 3) Archive a thread
Use `thread/archive` to move the persisted rollout (stored as a JSONL file on disk) into the archived sessions directory.
```json
{ "method": "thread/archive", "id": 21, "params": { "threadId": "thr_b" } }
{ "id": 21, "result": {} }
```
An archived thread will not appear in future calls to `thread/list`.
### 4) Start a turn (send user input)
Turns attach user input (text or images) to a thread and trigger LLMX generation. The `input` field is a list of discriminated unions:
- `{"type":"text","text":"Explain this diff"}`
- `{"type":"image","url":"https://…png"}`
- `{"type":"localImage","path":"/tmp/screenshot.png"}`
You can optionally specify config overrides on the new turn. If specified, these settings become the default for subsequent turns on the same thread.
```json
{ "method": "turn/start", "id": 30, "params": {
"threadId": "thr_123",
"input": [ { "type": "text", "text": "Run tests" } ],
// Below are optional config overrides
"cwd": "/Users/me/project",
"approvalPolicy": "unlessTrusted",
"sandboxPolicy": {
"mode": "workspaceWrite",
"writableRoots": ["/Users/me/project"],
"networkAccess": true
},
"model": "gpt-5-llmx",
"effort": "medium",
"summary": "concise"
} }
{ "id": 30, "result": { "turn": {
"id": "turn_456",
"status": "inProgress",
"items": [],
"error": null
} } }
```
### 5) Interrupt an active turn
You can cancel a running Turn with `turn/interrupt`.
```json
{ "method": "turn/interrupt", "id": 31, "params": {
"threadId": "thr_123",
"turnId": "turn_456"
} }
{ "id": 31, "result": {} }
```
The server requests cancellations for running subprocesses, then emits a `turn/completed` event with `status: "interrupted"`. Rely on the `turn/completed` to know when LLMX-side cleanup is done.
## Auth endpoints
The JSON-RPC auth/account surface exposes request/response methods plus server-initiated notifications (no `id`). Use these to determine auth state, start or cancel logins, logout, and inspect ChatGPT rate limits.
### Quick reference
- `account/read` — fetch current account info; optionally refresh tokens.
- `account/login/start` — begin login (`apiKey` or `chatgpt`).
- `account/login/completed` (notify) — emitted when a login attempt finishes (success or error).
- `account/login/cancel` — cancel a pending ChatGPT login by `loginId`.
- `account/logout` — sign out; triggers `account/updated`.
- `account/updated` (notify) — emitted whenever auth mode changes (`authMode`: `apikey`, `chatgpt`, or `null`).
- `account/rateLimits/read` — fetch ChatGPT rate limits; updates arrive via `account/rateLimits/updated` (notify).
### 1) Check auth state
Request:
```json
{ "method": "account/read", "id": 1, "params": { "refreshToken": false } }
```
Response examples:
```json
{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": false } } // No OpenAI auth needed (e.g., OSS/local models)
{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": true } } // OpenAI auth required (typical for OpenAI-hosted models)
{ "id": 1, "result": { "account": { "type": "apiKey" }, "requiresOpenaiAuth": true } }
{ "id": 1, "result": { "account": { "type": "chatgpt", "email": "user@example.com", "planType": "pro" }, "requiresOpenaiAuth": true } }
```
Field notes:
- `refreshToken` (bool): set `true` to force a token refresh.
- `requiresOpenaiAuth` reflects the active provider; when `false`, LLMX can run without OpenAI credentials.
### 2) Log in with an API key
1. Send:
```json
{ "method": "account/login/start", "id": 2, "params": { "type": "apiKey", "apiKey": "sk-…" } }
```
2. Expect:
```json
{ "id": 2, "result": { "type": "apiKey" } }
```
3. Notifications:
```json
{ "method": "account/login/completed", "params": { "loginId": null, "success": true, "error": null } }
{ "method": "account/updated", "params": { "authMode": "apikey" } }
```
### 3) Log in with ChatGPT (browser flow)
1. Start:
```json
{ "method": "account/login/start", "id": 3, "params": { "type": "chatgpt" } }
{ "id": 3, "result": { "type": "chatgpt", "loginId": "<uuid>", "authUrl": "https://chatgpt.com/…&redirect_uri=http%3A%2F%2Flocalhost%3A<port>%2Fauth%2Fcallback" } }
```
2. Open `authUrl` in a browser; the app-server hosts the local callback.
3. Wait for notifications:
```json
{ "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": true, "error": null } }
{ "method": "account/updated", "params": { "authMode": "chatgpt" } }
```
### 4) Cancel a ChatGPT login
```json
{ "method": "account/login/cancel", "id": 4, "params": { "loginId": "<uuid>" } }
{ "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": false, "error": "…" } }
```
### 5) Logout
```json
{ "method": "account/logout", "id": 5 }
{ "id": 5, "result": {} }
{ "method": "account/updated", "params": { "authMode": null } }
```
### 6) Rate limits (ChatGPT)
```json
{ "method": "account/rateLimits/read", "id": 6 }
{ "id": 6, "result": { "rateLimits": { "primary": { "usedPercent": 25, "windowDurationMins": 15, "resetsAt": 1730947200 }, "secondary": null } } }
{ "method": "account/rateLimits/updated", "params": { "rateLimits": { … } } }
```
Field notes:
- `usedPercent` is current usage within the OpenAI quota window.
- `windowDurationMins` is the quota window length.
- `resetsAt` is a Unix timestamp (seconds) for the next reset.
### Dev notes
- `llmx app-server generate-ts --out <dir>` emits v2 types under `v2/`.
- `llmx app-server generate-json-schema --out <dir>` outputs `llmx_app_server_protocol.schemas.json`.
- See [“Authentication and authorization” in the config docs](../../docs/config.md#authentication-and-authorization) for configuration knobs.

## `apply_patch`
Use the `apply_patch` shell command to edit files.
Your patch language is a strippeddown, fileoriented diff format designed to be easy to parse and safe to apply. You can think of it as a highlevel envelope:
*** Begin Patch
[ one or more file sections ]
*** End Patch
Within that envelope, you get a sequence of file operations.
You MUST include a header to specify the action you are taking.
Each operation starts with one of three headers:
*** Add File: <path> - create a new file. Every following line is a + line (the initial contents).
*** Delete File: <path> - remove an existing file. Nothing follows.
*** Update File: <path> - patch an existing file in place (optionally with a rename).
May be immediately followed by *** Move to: <new path> if you want to rename the file.
Then one or more “hunks”, each introduced by @@ (optionally followed by a hunk header).
Within a hunk each line starts with:
For instructions on [context_before] and [context_after]:
- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first changes [context_after] lines in the second changes [context_before] lines.
- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:
@@ class BaseClass
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
- If a code block is repeated so many times in a class or function such that even a single `@@` statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:
@@ class BaseClass
@@ def method():
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
The full grammar definition is below:
Patch := Begin { FileOp } End
Begin := "*** Begin Patch" NEWLINE
End := "*** End Patch" NEWLINE
FileOp := AddFile | DeleteFile | UpdateFile
AddFile := "*** Add File: " path NEWLINE { "+" line NEWLINE }
DeleteFile := "*** Delete File: " path NEWLINE
UpdateFile := "*** Update File: " path NEWLINE [ MoveTo ] { Hunk }
MoveTo := "*** Move to: " newPath NEWLINE
Hunk := "@@" [ header ] NEWLINE { HunkLine } [ "*** End of File" NEWLINE ]
HunkLine := (" " | "-" | "+") text NEWLINE
A full patch can combine several operations:
*** Begin Patch
*** Add File: hello.txt
+Hello world
*** Update File: src/app.py
*** Move to: src/main.py
@@ def greet():
-print("Hi")
+print("Hello, world!")
*** Delete File: obsolete.txt
*** End Patch
It is important to remember:
- You must include a header with your intended action (Add/Delete/Update)
- You must prefix new lines with `+` even when creating a new file
- File references can only be relative, NEVER ABSOLUTE.
You can invoke apply_patch like:
```
shell {"command":["apply_patch","*** Begin Patch\n*** Add File: hello.txt\n+Hello, world!\n*** End Patch\n"]}
```

//! This module is responsible for parsing & validating a patch into a list of "hunks".

//! The official Lark grammar for the apply-patch format is:
//!
//! start: begin_patch hunk+ end_patch
//! begin_patch: "*** Begin Patch" LF
//! end_patch: "*** End Patch" LF?
//!
//! hunk: add_hunk | delete_hunk | update_hunk
//! add_hunk: "*** Add File: " filename LF add_line+
//! delete_hunk: "*** Delete File: " filename LF
//! update_hunk: "*** Update File: " filename LF change_move? change?
//! filename: /(.+)/
//! add_line: "+" /(.+)/ LF -> line
//!
//! change_move: "*** Move to: " filename LF
//! change: (change_context | change_line)+ eof_line?
//! change_context: ("@@" | "@@ " /(.+)/) LF
//! change_line: ("+" | "-" | " ") /(.+)/ LF
//! eof_line: "*** End of File" LF
//!
//! The parser below is a little more lenient than the explicit spec and allows for
//! leading/trailing whitespace around patch markers.
