## Summary - prefer tmux's native clipboard integration for `/copy` when running inside tmux - fall back to OSC 52 when tmux clipboard copy is unavailable - add coverage for tmux-preferred, fallback, and combined-failure paths ## Why Inside tmux, `/copy` previously relied on DCS-wrapped OSC 52 when `TMUX` was set. That only reaches the outer terminal when tmux passthrough is enabled, so Codex could report success even though the system clipboard never changed. ## User impact `/copy` now works inside tmux even when `allow-passthrough` is off, as long as tmux clipboard integration is available. If tmux cannot handle the copy, Codex still keeps the existing OSC 52 fallback path. ## Validation - `cargo test -p codex-tui` - `just fmt` - `just fix -p codex-tui` - `just argument-comment-lint` - manually verified `/copy` inside tmux with `allow-passthrough off` Fixes #19926
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.
