## Summary `ChatWidget` has been carrying several independent domains in one large state bag: transcript bookkeeping, turn lifecycle, queued input, status surfaces, connectors, review mode, and protocol dispatch. That makes otherwise-local changes hard to reason about because unrelated fields and side effects live beside each other in `chatwidget.rs`. This is the first cleanup PR in a larger decomposition effort. It does not try to make `chatwidget.rs` small in one sweep; instead, it establishes focused state boundaries that later handler, popup, rendering, and effect-synchronization extractions can build on. This PR keeps `ChatWidget` as the composition layer while moving focused state into smaller `codex-tui` modules. The widget still owns effects that touch the bottom pane, app events, command submission, redraw scheduling, and terminal-title updates. ## Changes - Add focused state modules under `codex-rs/tui/src/chatwidget/` for input queues, turn lifecycle, transcript bookkeeping, status state, connectors, review mode, and app-server protocol dispatch. - Update `ChatWidget` to hold grouped state structs and route input/lifecycle/status operations through those focused helpers. - Move app-server notification dispatch into `chatwidget/protocol.rs` while leaving feature handlers and side effects on `ChatWidget`. - Replace the large manual `ChatWidget` test literal with the normal constructor plus narrow test overrides, so future state moves do not require every field to be restated in test setup. - Update existing tests to access the new grouped state or narrower helpers without changing snapshot behavior. ## Longer-term direction Follow-up PRs can continue shrinking `chatwidget.rs` by moving behavior, not just state, into focused modules: - Extract input/submission flow, turn/stream handling, and tool-cell lifecycles into domain modules that call the new state reducers. - Move popup/settings builders and rendering helpers out of the main widget file so `ChatWidget` stays focused on composition. - Reduce direct `BottomPane` mutation by applying domain-specific sync outputs at clearer boundaries.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
