User-facing symptom: On terminals that deliver pastes as rapid KeyCode::Char/Enter streams (notably Windows), paste-burst transient state can leak into the next input. Users can see Enter insert a newline when they meant to submit, or see characters appear late / handled through the wrong path. System problem: PasteBurst is time-based. Clearing only the classification window (e.g. via clear_window_after_non_char()) can erase last_plain_char_time without emitting buffered text. If a buffer is still non-empty after that, flush_if_due() no longer has a timeout clock to flush against, so the buffer can get "stuck" until another plain char arrives. This was surfaced while adding deterministic regression tests for paste-burst behavior. Fix: when disabling burst detection, defuse any in-flight burst state: flush held/buffered text through handle_paste() (so it follows normal paste integration), then clear timing and Enter suppression. Document the rationale inline and update docs/tui-chat-composer.md so "disable_paste_burst" matches the actual behavior.
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 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.
