## 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. This PR is phase 3. It keeps moving high-churn event handling out of the central widget by extracting protocol, replay, streaming, and tool lifecycle handling without changing the visible behavior those flows already provide. This is once again just a mechanical movement of existing functions. No functional changes. ## What Changed - Added focused modules for protocol request dispatch, replay rendering, assistant/plan/reasoning streaming, turn runtime bookkeeping, hook lifecycle handling, command lifecycle handling, tool lifecycle rendering, and interactive tool request prompts. - Kept active-cell grouping, transcript invalidation, interrupt deferral, and final-message separator behavior in the same flows, just moved into smaller files. - Added module header comments to the new files so the ownership boundaries are explicit. - Left `codex-rs/tui/src/chatwidget.rs` as the registration and orchestration surface for these extracted behaviors. ## 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. This PR. 4. Phase 4: extract settings, popups, and status surfaces, including model/reasoning/collaboration/personality popups, permission prompts, rate-limit UI, and connectors helpers. 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.
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.
