## Why `chatwidget.rs` is still carrying too many unrelated responsibilities in one file. After #21866 consolidated some of the state it tracks, this starts the next phase by moving coherent state/helper clusters out of the main module without changing behavior. This PR is intentionally mechanical: it only moves existing functions, structs, and helpers into focused modules so the boundaries are easier to review before the less mechanical refactors that should follow. ## What Changed - Moved user-message, composer, queue, pending steer, and merge/remap helpers into `codex-rs/tui/src/chatwidget/user_messages.rs`. - Added `codex-rs/tui/src/chatwidget/exec_state.rs` for unified exec bookkeeping helpers. - Added `codex-rs/tui/src/chatwidget/rate_limits.rs` for rate-limit warning, prompt, and error classification state. - Moved plugin list fetch and install auth-flow state into `codex-rs/tui/src/chatwidget/plugins.rs`. - Made a couple of test-only `VecDeque` imports explicit now that those tests no longer inherit the parent module import. ## Verification - `cargo test -p codex-tui` was run ## Follow-On Refactor Phases This PR is phase 1: mechanical helper and state moves. Planned follow-up PRs: - Phase 2: extract input and submission flow, including queued user messages, shell prompt submission, pending steer restoration, and thread input snapshot/restore behavior. - Phase 3: extract protocol, replay, streaming, and tool lifecycle handling, while preserving active-cell grouping, transcript invalidation, interrupt deferral, and final-message separator behavior. - Phase 4: extract settings, popups, and status surfaces, including model/reasoning/collaboration/personality popups, permission prompts, rate-limit UI, and connectors helpers. - 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.
