## Why `chatwidget.rs` is still carrying too many unrelated responsibilities in one file. #22269 started a five-phase cleanup to move coherent behavior domains into focused modules while keeping `chatwidget.rs` as the composition layer. #22407 completed phase 2 by extracting input and submission flow, #22433 completed phase 3 by extracting protocol, replay, streaming, and tool lifecycle handling, and #22518 completed phase 4 by extracting settings, popups, and status surfaces. This PR is phase 5. It cleans up the remaining constructor and orchestration code now that the larger behavior domains have moved out, leaving `chatwidget.rs` much closer to the composition layer the cleanup was aiming for. This is once again a mechanical movement of existing functions. No functional changes. ## What Changed - Added focused modules for widget construction and initial wiring, session configuration flow, key/composer interaction routing, review popup orchestration, desktop notification coalescing, and render composition. - Moved the remaining constructor, session setup, interaction, notification, review picker, and rendering helpers out of `codex-rs/tui/src/chatwidget.rs`. - Preserved the existing startup/session behavior, keyboard handling, review picker flow, notification priority behavior, and render composition while shrinking the central widget module substantially. - Left `codex-rs/tui/src/chatwidget.rs` as the registration and composition surface for the extracted behavior modules. ## Cleanup Phases The five-phase cleanup plan from #22269 is: 1. Phase 1: mechanical helper and state moves. Completed in #22269. 2. Phase 2: extract input and submission flow, including queued user messages, shell prompt submission, pending steer restoration, and thread input snapshot/restore behavior. Completed in #22407. 3. Phase 3: extract protocol, replay, streaming, and tool lifecycle handling, while preserving active-cell grouping, transcript invalidation, interrupt deferral, and final-message separator behavior. Completed in #22433. 4. Phase 4: extract settings, popups, and status surfaces, including model/reasoning/collaboration/personality popups, permission prompts, rate-limit UI, and connectors helpers. Completed in #22518. 5. Phase 5: clean up the remaining constructor and orchestration code once the larger behavior domains have moved out, leaving `chatwidget.rs` as the composition layer. This PR. ## Verification - `cargo check -p codex-tui` - `cargo test -p codex-tui chatwidget::tests::popups_and_settings` - `cargo test -p codex-tui chatwidget::tests::plan_mode` - `cargo test -p codex-tui chatwidget::tests::review_mode` - `cargo test -p codex-tui chatwidget::tests::status_and_layout` `cargo test -p codex-tui` also compiles and begins running, but aborts in the unchanged app-side test `app::tests::discard_side_thread_keeps_local_state_when_server_close_fails` with the same reproducible stack overflow noted in phase 4.
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.
