Fixes #20587, reported by @noeljackson. This prevents the TUI wrapping code from panicking when `textwrap` returns a borrowed slice that does not point into the original source text. The fix follows the direction proposed by @misrtjakub in the issue comment: validate the borrowed slice pointer range first, and fall back to the existing owned-line mapper when the slice is external. - Guards borrowed wrapped slices before converting pointer offsets into byte ranges. - Reuses the existing owned-line range recovery path for external borrowed slices. - Adds coverage for rejecting borrowed slices outside the source text. End-user testing steps: - Start Codex in TUI mode under a PTY wrapper that can inject stdin after startup. - Inject `\x1b[200~test message\x1b[201~\r` after the TUI is ready. - Confirm Codex does not panic and the pasted text is handled normally. Local validation: - `cargo test -p codex-tui wrapping::tests::` - `cargo test -p codex-tui -- --skip status::tests::status_permissions_full_disk_managed_with_network_is_danger_full_access --skip status::tests::status_permissions_full_disk_managed_without_network_is_external_sandbox`
npm i -g @openai/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.
